Answer:
20 leaves
Step-by-step explanation:
Step one:
given data
we are told that the amount paid =$30
The mean man deducts $3 for every 2 leaves seen on the lawn.
we are expected to estimate the number of leaves that can amount to a $30 deduction.
Step two:
let the number of leaves be x
so if 2 leaves are worth $3 deductible
the x leave will worth $30 deductible
cross multiply we have
x=30*2/3
x=60/3
x=20 leaves
is y= -7x linear or non linear
Answer:
I think Linear but i am not sure
Step-by-step explanation:
A linear function is a function with standard form y = mx + b, where m is the slope and b is the y-intercept, and whose graph looks like a straight line. There are other functions whose graph is not a straight line. These functions are known as nonlinear functions and they come in many different forms.
determine the slope and the y-intercept
Answer:
B m = 1/2 y-int = -1
Step-by-step explanation:
at x = 0, y=-1 so that is the y-intercept
to find the slope, use the slope formula m=(y2-y1)/(x2-x1)
m=(0--1)/(2-0)
m=1/2

c. Sophia's friend has saved $118 but is not sure how many songs she can afford if she buys the
membership and some songs. Use the expression in part (b) to write an equation that can be used to
determine how many songs Sophia's friend can buy.
okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total

The baker can make 28 cakes
in 7 days. How many cakes can
the baker make in 5 days?
B
Enter your text here
Answer:
20 cakes
Step-by-step explanation:
Given
28 cakes in 7 days
Required
Determine the number of cakes in 5 days
Represent the required with x. The question illustrates proportionality.
First, we need to represent the given and required as a ratio
[tex]28 : 7 = x : 5[/tex]
Convert ratios to fraction
[tex]\frac{28}{7} = \frac{x}{5}[/tex]
[tex]4 = \frac{x}{5}[/tex]
Solve for x
[tex]x = 4 * 5[/tex]
[tex]x = 20[/tex]
A student solved log4(2x – 12) = 3, as shown.
Answer:
x = -6
Step-by-step explanation:
you want to solve the aswer so you wanna solve for whats in the parenthesis so your new equation should look like this:
8x + 48 = 3
you want to subtract 48 from both sides your new equation should look like this:
8x = -45
now you want to get x by itself and your new equation should be:
x = -6

To determine the height of a pine tree, you measure the shadow cast by the tree and find it to be 20 feet long. Then you measure the shadow cast by a 36-inch tall oak sapling and find it to be d= 12 inches long (see figure). Estimate the height of the pine tree.
Answer:
Height of the pine tree = 60 in.
Step-by-step explanation:
Since, triangle formed by the tip of the tree and tip of the shadow of the tree will be similar to each other,
By the property of similarity, corresponding sides of the similar triangles will be proportional.
[tex]\frac{x}{20}=\frac{36}{d}[/tex]
If d = 12 inches,
[tex]\frac{x}{20}=\frac{36}{12}[/tex]
x = [tex]\frac{20\times 36}{12}[/tex]
x = 60 in.
Therefore, height of the pine tree will be 60 in.

While in France, Judy wants to sign up for a bike tour to see the countryside. She likes a tour that is 40 kilometers long, but she isn't sure how far that is. She decides to estimate the distance in miles. If Judy uses the fact that 1 kilometer is about 0.6 miles, what will her estimate be?
Answer:
24 miles
Step-by-step explanation:
In order to calculate Judy's estimation, we would simply have to multiply the actual distance in kilometers of the tour by the number of miles that Judy believes are in a single mile. This would give us Judy's estimation for how long the tour would be in miles.
40 km. * 0.6 miles = 24 miles
Finally, we can see that Judy's estimation would be that the tour is 24 miles long. Using Judy's believed conversion rate.

A city had a population of 2,425 and was growing by 27 residents per year. City B had a population of 1,813 and was growing by 63 residents per year. If this continues, how many years will it take for them to be the same?
Answer:
17 years
Step-by-step explanation:
In order to calculate this, we need to create an equality equation. In this scenario, we have the fixed values which are the total population and the rate of growth, and we also have one variable which is the number of years. We can use these values to create the following equation.
2,425 + 27x = 1,813 + 63x
Now that we have the equation we can solve for x to calculate how many years it will take for them to be the same population.
2,425 + 27x = 1,813 + 63x ... subtract 1,813 and 27x from both sides
612 = 36x ... divide both sides by 36
17 = x
Finally, we can see that both populations will be the same after 17 years.
Which values are two of the possible solutions to the equation? sin(5x-pi)= sqrt2/2, for x is greater than or equal to 0 and less than 2pi
A) pi/20, 3pi/20
B) pi/4, 7pi/20
C) pi/4, 7pi/4
D) 5pi/4, 7pi/4
Answer:
B
Step-by-step explanation:
B
The two of the possible solutions to the equation sin(5x - π) = (√2)/2 are,
⇒ (π/4, 7π/4).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Here, The given equation is;
sin(5x - π) = (√2)/2
Now, We can write 2 as √2 × √2
So, We get;
sin(5x - π) = √2/√2*√2
sin(5x - π) = 1/√2
Taking sin⁻¹ on both side,
sin⁻¹ (sin(5x - π)) = sin⁻¹ (1/√2)
5x - π = sin⁻¹ (1/√2)
Hence, From the trigonometry table we know that sin⁻¹ (1/√2) = π/4
Thus,
5x - π = π/4
5x = π + π/4
5x = 5/4π
Divide by 5 on both side, we get
x = π/4
Now, since x < 2π, then it means it is in the fourth quadrant. Thus;
x = 7π/4
So, the two of the possible solutions to the equation sin(5x - π) = (√2)/2 is (π/4, 7π/4).

What is the center and radius of the circle with the given equation? [tex]x^2+y^2+2x+8y=8[/tex]
Answer:
(- 1, - 4 ) and r = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form from the given equation use the method of completing the square.
Given
x² + y² + 2x + 8y = 8 ( rearrange by collecting x and y terms )
x² + 2x + y² + 8y = 8
To complete the square
add ( half the coefficients of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(4)x + 16 = 8 + 1 + 16
(x + 1)² + (y + 4)² = 25 ← in standard form
with centre (h, k ) = (- 1, - 4 ) and r = [tex]\sqrt{25}[/tex] = 5

A magician charges parties a $30 fee to cover travel and miscellaneous expenses plus $19.99 per hour. Write an equation to represent the relationship between x, the number of hours, and y, the total charge for the magician.
Answer:
y = 19.99x + 30
Step-by-step explanation:
y = 19.99x + 30
The x represents the number of hours, and because it costs 19.99 per hour, the coefficient before the x will be 19.99. The y-intercept is the fee because it doesn't change with the x.
