Answer:
b=112°
Step-by-step explanation:
two complementary angles
b=180°-68°=112°
sum of 2 angles is
x= 35°+25°=60°
Answer:
3. b=112
4. x = 60
Step-by-step explanation:
3.
b is equal to 112 since 68+b will be equal to a supplementary angle; an angle that adds up to 180. 180-68 is equal to 112.
4.
35+25 = 60, therefore x = 60.

The scatter plot shows the time spent watching TV, x, and the time spent doing homework, y, by each of 23 students last week.
Answers
Answer:
[tex](a)\ y = -0.75x + 26[/tex]
[tex](b)\ y = 14.75[/tex]
Step-by-step explanation:
Given
See attachment for scatter plot
Required
Equation of the line of best fit
Pick any two points on the line
[tex](x_1,y_1) = (24,8)[/tex]
[tex](x_2,y_2) = (8,20)[/tex]
Calculate the slope (m)
[tex]m =\frac{y_2 -y_1}{x_2 -x_1}[/tex]
[tex]m =\frac{20-8}{8-24}[/tex]
[tex]m =\frac{12}{-16}[/tex]
[tex]m =-0.75[/tex]
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = -0.75(x - 24) + 8[/tex]
[tex]y = -0.75x + 18 + 8[/tex]
[tex]y = -0.75x + 26[/tex]
Solving (b): y, when [tex]x = 15[/tex]
[tex]y = -0.75x + 26[/tex] becomes
[tex]y = -0.75*15 + 26[/tex]
[tex]y = -11.25 + 26[/tex]
[tex]y = 14.75[/tex]
A fish-tank has a length of 27 centimeters, a width of 21 centimeters and a depth of 16 centimeters. Find the volume of the fish-tank.
Answers
Answer:
To find the volume of the fish tank, we will need to multiply the height, the length, and the width of the fish tank. So, 21 x 27 x 16 = 9072 cm
Answer:
9027 cm^3
Step-by-step explanation:
V= L*W*H
V=27cm*21cm*16cm
V=567*16
V=9072 cm^3
The cm is cubed because you are also multiplying cm*cm*cm So, it would be cm cubed or cm^3

Mirror the speed of 16.8 m/s Olympian ran the 100 m dash in 9.6 seconds how much faster was Sarah the cheetah speed to the nearest 10th of a meter per second
Answers
Answer:
6.4 meters per second
Step-by-step explanation:
Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second. An olympian ran the 100-meter dash in 9.6 seconds. How much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second?
0.9 meters per second
1.6 meters per second
6.4 meters per second
10.4 meters per second
Speed = distance / time
Olympian's speed = 100 / 9.6 = 10.4 meters per second
Sarah's speed = 16.8 meters per second.
Difference in speed = 16.8 - 10.4 = 6.4
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Find the value of x.
Answers
Answer:
Step-by-step explanation:
Vertically opposite angles are equal
8x + 2 = 7x + 11
Subtract 2 from both sides
8x = 7x + 11 - 2
8x = 7x + 9
Subtract 7x from both sides
8x - 7x = 9
x = 9

Problem 7) 25.2 feetProblem 8) Angle = 52 degrees; Distance = 14.3 feetProblem 9) DE = 22, EC = 10, BC = 20=====================================================
Explanation:
The diagrams for problems 7 and 8 are shown below.
------------------------------------
Problem 7
Apply the tangent ratio to find that...
tan(angle) = opposite/adjacent
tan(42) = x/28
28*tan(42) = x
x = 28*tan(42)
x = 25.2113132403396
x = 25.2
Make sure your calculator is in degree mode. One way to check is to type in tan(45) and you should get 1 as a result.
------------------------------------
Problem 8, part 1
To find the angle y, we must use the sine ratio
sin(angle) = opposite/hypotenuse
sin(y) = 18/23
y = arcsin(18/23)
y = 51.5000495907521
y = 52 degrees approximately
------------------------------------
Problem 8, part 2
We can use the pythagorean theorem to find the missing side x
a^2+b^2 = c^2
18^2+x^2 = 23^2
324+x^2 = 529
x^2 = 529-324
x^2 = 205
x = sqrt(205)
x = 14.3178210632763
x = 14.3
Or alternatively, we can apply the tangent ratio on the angle y we found earlier to help find x
tan(angle) = opposite/adjacent
tan(y) = 18/x
tan(51.50004959) = 18/x
x*tan(51.50004959) = 18
x = 18/tan(51.50004959)
x = 14.3178210636621
x = 14.3
------------------------------------
Problem 9
The double tickmarks show that BE = EC = 10. That means BC = BE+EC = 10+10 = 20.
Since we have similar triangles, we can solve for x like so
DE/AC = BE/BC
x/44 = 10/20
20x = 44*10
20x = 440
x = 440/20
x = 22
So DE is 22 units long. Note how this is half as long as the side AC = 44.
After a congruence transformation, how would the perimeter of the triangle be?

You wrote the question wrong...
m is not -16 it is -1/6 (that is a big difference)

3 = -2 + b
b=5

Miss Chambers bought 5 pens for $255, if she made a profit of $3 each per pen how much did she sell a pen for?
Answers
Answer:
$54
Step-by-step explanation:
First, we calculate the amount she paid for each pen.
$255/5 = $51
She paid $51 for each pen.
She made a profit of $3 per pen, so she sold each pen for $51 + $3 = $54
Answer: $54

Your purchase a T-shirt with a label pre-tax price of $17 the local sale price rate is 5% what is your final cost including tax
Answers
Answer: $17.85
Step-by-step explanation:
The tax on the T-shirt is 5% and the price is $17.
To find the after-tax cost, first find the tax amount:
= 5% * 17
= $0.85
Then add this tax amount to the price to find the after-tax amount:
= 17 + 0.85
= $17.85

A mobile set is sold for Rs 6,630 after a discount of 15%. Find the marked price of the mobile set.
Answers
Answer:
MP = RS 7,800
Step-by-step explanation:
Let
Marked price = MP
MP x (100 – 15) / 100 = Rs 6,630
MP × (85)/100 = Rs 6,630
MP = Rs 6,630 ÷ 85/100
MP = 6,630 × 100/85
MP = 663,000/85
MP = 7,800
MP = RS 7,800
