<A = <E corresponding parts of 2 geometric figures are =
60 + 8x = 108 Subtract 60 from both sides
8x = 108 - 60 Combine
8x = 48 Divide by 8
8x/8 = 48/8
x = 6
< C = <G corresponding parts of 2 geometric figures are =
8y - 3x = 62 Use x = 6 from the previous problem
8y - 3*6 = 62 Combine
8y - 18 = 62 Add 18 to both sides
8y = 62 + 18 Combine
8y = 80 Divide by 8
8y/8 = 80/8
y = 10

Answer:
w=4
Step-by-step explanation:
First, we can simplify the equation.
28=14w-7w
28=7w
Then, we can divide by 7 on both sides of the equation.
28/7=7w/7
4=w
Finally, we know that x equals 4.
Answer:
w =4
Step-by-step explanation:
28 = 14w - 7w
Combine like terms
28 = 7w
Divide both sides of the equation by the same term
28/7 = 7w/7
Simplify
w = 4

The scatter plot shows the number of minutes people had to wait for service at a restaurant and the number of staff available at the time.
A line that models the data is given by the equation $$, where $$ represents the wait time, and represents the number of staff available.
The slope of the line is -1.62. What does this mean in this situation?
the time you have to wait per staff number.
Is a slope of 1.62 realistic in this context?
no because it is not a coordinate and there isn't any decimals in the wait time
The $$-intercept is $$. What does this mean in this situation?
it means there's more waiting time
Is a $$-intercept of $$ realistic in this context?
no because when you try to find it it goes off the graph and isnt calculable.
The slope of a linear regression is the rate of change of the line of the best fit
The interpretation of the slope is that the wait time per staff is 1.62 minutesThe slope value is realisticThe linear regression is given as:
y = -1.62x + 18
Where
y represents the wait timex represents the number of staffUsing the above representations, the slope means that the wait time per staff is 1.62 minutes
Also, the slope value is realistic because time can be measured in decimals

Answer:
hi and hello and welcome to the internet
Answer:
AOS: -4
Vertex: (-4,2)
X-intercepts: (-6,0) , (-2,0)
Y-intercept: (0,6)
Step-by-step explanation:
The Parabola opens upwards (as can be seen in the image.) To find the AOS (Axis of Symmetry) first identify the vertex (-4,2) and take the X value of it.
So the AOS is x = -4
Vertex is (-4,2)
The x-intercepts are seen in the graph, (-6,0) and (-2,0)
The y-intercept is where the parabola first touches the Y-axis, which as can be seen is, (0,6).

Step-by-step explanation: You will be focusing on PEMDAS if you know the term. Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction, all in the order shown. Since there is no parenthesis or exponent, we go with multiplication as the first option in this problem. 16 x 3 and 3 x 3. 16 x 3 = 48, and 3 x 3 = 9. Since there is no Division on here, we will go the addition, where you add all the numbers up. 48 + 4 = 52 + 9 = 61

Answer:
[tex]area = \frac{1}{2} (base)(height) \\ area = \frac{1}{2} (35cm)(12cm) \\ area = \frac{1}{2} (420 {cm}^{2} ) \\ area = 210 \: {cm}^{2} [/tex]
The area of the triangle with height 12 cm and base 35 cm is A = 210 cm²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle is AB = 35 cm
The height of the triangle is BC = 12 cm
And , the area of the triangle = ( 1/2 ) x Length x Base
On simplifying , we get
Area of the triangle A = ( 1/2 ) x 12 x 35
Area of the triangle A = ( 6 x 35 )
Area of the triangle A = 210 cm²
Hence , the area of the triangle is 210 cm²

The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks, and it will cost an additional $125 for each ton of sugar
transported.
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this
equation to find the total cost to transport 18 tons of sugar.
Answer:
$ 3750 = truck rental; $125 per ton of sugar transported
C is cost; S is number of tons transported
Equation relating C to S would be a linear equation like y = mx + b
C = 125S + $3750
This equation would be graphed in the first quadrant only
you would start with your y-intercept at (0, 3750)
As x increases by 1, your y increases by 125 yielding these points:
(1, 3875) (2, 4000) (3, 4125) etc.
This shows that for each increase by one ton of sugar, the cost goes up $125

Convert 39/50 to a decimal and a percent.
Answer:
here's your answer hope it helps.
Step-by-step explanation:
1. decimal:
39/50=0.78
2. percentage:
39/50=78%
9/50 to a decimal is 0.78 and a percent is 78%.
To convert fraction into decimal, divide the top of the fraction by the bottom number (39/50) here 39 is the top of the fraction and 50 is bottom of the fraction.
39/50 = 0.78
To convert fraction into percent, divide the top of the fraction by the bottom number then multiple the result by 100 here 39 is the top of the fraction and 50 is bottom of the fraction then multiple the result(0.78) by 100.
39/50 = 0.78 * 100 = 78.
Therefore, 39/50 to a decimal is 0.78 and a percent is 78%.

Section 8.1 Introduction to the Laplace Transforms
Problem 2.
Use the table of Laplace transforms to find the Laplace transforms of the following functions.
[tex](a)cosh \: t \: sin \: t[/tex]
[tex](b) {sin}^{2} t[/tex]
[tex](c) {cos}^{2} 2t[/tex]
[tex](d) {cosh}^{2} t[/tex]

[tex](g)sin(t + \frac{\pi}{4} )[/tex]
[tex](h)cos2t - cos3t[/tex]
[tex](i)sin2t + cos4t[/tex]
I don't know what table you have as reference, but I suspect it includes the following transforms:
[tex]1 \leftrightarrow \dfrac1s[/tex]
[tex]e^{at} \leftrightarrow \dfrac{1}{s-a}[/tex]
[tex]\cos(at) \leftrightarrow \dfrac{s}{s^2+a^2}[/tex]
[tex]\sin(at) \leftrightarrow \dfrac{a}{s^2+a^2}[/tex]
[tex]\cosh(at) \leftrigharrow \dfrac{s}{s^2-a^2}[/tex]
[tex]\sinh(at) \leftrigharrow \dfrac{a}{s^2-a^2}[/tex]
It probably also includes some more general properties, like
[tex]t f(t) \leftrightarrow -F'(s)[/tex]
[tex]e^{at} f(t) \leftrightarrow F(s-a)[/tex]
where F(s) is the Laplace transform of f(t).
Beyond these, you should also know the following identities:
[tex]\cosh(t) = \dfrac{e^t + e^{-t}}2[/tex]
[tex]\cosh^2(t) = \dfrac{1 + \cosh(2t)}2[/tex]
[tex]\cos^2(t) = \dfrac{1 + \cos(2t)}2[/tex]
[tex]\sin^2(t) = \dfrac{1 - \cos(2t)}2[/tex]
[tex]\sin(2t) = 2 \sin(t) \cos(t)[/tex]
[tex]\sin(t \pm T) = \sin(t) \cos(T) \pm \cos(t) \sin(T)[/tex]
Putting everything together, we have
• (a)
[tex]\cosh(t) \sin(t) = \dfrac{e^t + e^{-t}}2 \times \sin(t) = \dfrac12 e^t \sin(t) + \dfrac12 e^{-t} \sin(t)[/tex]
and the Laplace transform is
[tex]\dfrac12 F(s - 1) + \dfrac12 F(s + 1)[/tex]
where F(s) is the transform of sin(t),
[tex]F(s) = \dfrac{1}{s^2 + 1}[/tex]
Then
[tex]\cosh(t) \sin(t) \leftrightarrow \dfrac{\frac1{(s-1)^2+1} + \frac1{(s+1)^2+1}}2 = \boxed{\dfrac{s^2+2}{s^4+4}}[/tex]
• (b)
[tex]\sin^2(t) = \dfrac12 \left(1 - \cos(2t)\right)[/tex]
and the transform is
[tex]F(s) = \dfrac12 \left(\dfrac1s - \dfrac{s}{s^2+4}\right) = \boxed{\dfrac{2}{s^3+4s}}[/tex]
• (c)
[tex]\cos^2(2t) = \dfrac12 \left(1 + \cos(4t)\right)[/tex]
with transform
[tex]F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2+16}\right) = \boxed{\dfrac{s^2+8}{s^3+16s}}[/tex]
• (d)
[tex]\cosh^2(t) = \dfrac12 \left(1 + \cosh(2t)\right)[/tex]
with transform
[tex]F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2-4}\right) = \boxed{-\dfrac2{s^3-4s}}[/tex]
• (e)
[tex]t\sinh(2t) \leftrightarrow -F'(s)[/tex]
where F(s) is the Laplace transform of sinh(2t),
[tex]F(s) = \dfrac{2}{s^2 - 4} \implies -F'(s) = \boxed{\dfrac{4s}{(s^2-4)^2}}[/tex]
• (f)
[tex]\sin(t) \cos(t) = \dfrac12 \left(2\sin(t) \cos(t)\right) = \dfrac12 \sin(2t)[/tex]
with transform
[tex]F(s) = \dfrac12 \times \dfrac{2}{s^2+4} = \boxed{\dfrac1{s^2+4}}[/tex]
• (g)
[tex]\sin\left(t+\dfrac\pi4\right) = \sin(t) \cos\left(\dfrac\pi4\right) + \cos(t) \sin\left(\dfrac\pi4\right) = \dfrac1{\sqrt2} \left(\sin(t) + \cos(t)\right)[/tex]
with transform
[tex]F(s) = \dfrac1{\sqrt2} \left(\dfrac1{s^2+1} + \dfrac{s}{s^2+1}\right) = \boxed{\dfrac{s+1}{\sqrt2 (s^2+1)}}[/tex]
The last two are trivial and follow directly from the properties listed above.
• (h)
[tex]\cos(2t) - \cos(3t) \leftrightarrow \dfrac{s}{s^2+4} - \dfrac{s}{s^2+9} = \boxed{\dfrac{5s}{s^4 + 13s^2 + 36}}[/tex]
• (i)
[tex]\sin(2t) + \cos(4t) \leftrightarrow \dfrac2{s^2+4} + \dfrac{s}{s^2+16} = \boxed{\dfrac{s^3+2s^2+4s+32}{s^4+20s^2+64}}[/tex]

a theme park had 1099 vistiors in three day.
there were twicw as many vistiors on saturday.
than on friday.there were 234 more vistiors on sunday than on saturday.
how many visitors
Answer:
Number of visitors on Friday = 173
Number of visitors on Saturday = 346
Number of visitors on Sunday = 580
Step-by-step explanation:
Total number of visitors over 3 days = 1099
Let x = number of visitors on Friday
If there were twice as many visitors on Saturday than on Friday, then
⇒ number of visitors on Saturday = 2x
If there were 234 more visitors on Sunday than on Saturday, then
⇒ number of visitors on Sunday = 2x + 234
Create an expression for the total number of visitors and solve for x:
⇒ x + 2x + 2x + 234 = 1099
⇒ 5x + 234 = 1099
⇒ 5x = 865
⇒ x = 173
Substitute found value of x into the expressions for each day:
⇒ Number of visitors on Friday = 173
⇒ Number of visitors on Saturday = 2 x 173 = 346
⇒ Number of visitors on Sunday = (2 x 173) + 234 = 580

square root 2x/ square root x - 2 = 2
Answer:
[tex]x= 4[/tex]
Step-by-step explanation:
[tex]\frac{\sqrt{2x}}{\sqrt{x-2}\:}=2[/tex] [ bring √(x - 2) to the opposite side ]
[tex]\sqrt{2x} = 2\sqrt{x-2}[/tex]
[tex](\sqrt{2x} )^{2} = (2\sqrt{x-2})^2[/tex] [ square both sides ]
[tex]2x = 4(x-2)[/tex]
[tex]2x=4x-8[/tex]
[tex]2x - 4x = -8[/tex]
[tex]-2x = -8[/tex]
[tex]x= 4[/tex]
Answer:
x=4
Step-by-step explanation:
[tex]\dfrac{\sqrt{2x} }{\sqrt{x-2}}=2[/tex]
Multiply both sides by [tex]\sqrt{x-2}[/tex] :
[tex]\implies \sqrt{2x}=2\sqrt{x-2}[/tex]
Square both sides:
[tex]\implies 2x=4(x-2)\\\\\implies 2x=4x-8[/tex]
Add 8 to both sides:
[tex]\implies 2x+8=4x[/tex]
Subtract [tex]2x[/tex] from both sides:
[tex]\implies 8=2x[/tex]
Divide both sides by 4:
[tex]\implies x=4[/tex]
Put the following equation of a line into slope-intercept form, simplifying all fractions.
15x-9y= −9
The equation of a line in slope intercept form is given by:
y = mx + c
The equation 15x - 9y = -9 of a line into slope-intercept form after simplifying all fractions is y = (5/3)x + 1
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
y = 2x - 3
y = 3x + 4
We have,
15x - 9y = -9
We will rewrite in the slope-intercept form of y = mx + c.
15x - 9y = -9
Subtract 15x on both sides.
-9y = -9 - 15x
-9y = -15x - 9
Divide both sides by -9.
y = (-15x - 9) / -9
y = (15/9)x + 1
y = (5/3)x + 1
Slope = m = 5/3
y-intercept = 1
This is in the slope-intercept form of y = mx + c.
Thus,
The equation 15x - 9y = -9 of a line into slope-intercept form after simplifying all fractions is
y = (5/3)x + 1

kali runs 10 laps around a track each day. Each lap around the track is 400 meters. How many will it take kali to run a total of 12 kilometers?
Answer:
3 days
Step-by-step explanation:
Kali runs 10 laps around a track each day, and each lap is 400 meters. So, the first step would be:
10 • 400 = 4,000
That means Kali runs 4,000 meters each day.
Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.
The final step is to divide. 12/4 = 3
So, it would take 3 days for him to run a total of 12 kilometers.
