Susan is 5.5 ft tall and casts a shadow that it is 4 ft long on the ground. She is walking through a park and finds the shadow of a sculpture is 16 ft long. How tall is the sculpture?
Answer:
22 ft
Step-by-step explanation:
Height of Susan/Length of shadow = Height of sculpture/Length of Shadow of sculpture
5.5 ft/4 ft = x/16ft
Cross Multiply
4 × x = 5.5 × 16
x = 5.5 × 16/4
x = 22 ft
The height of the sculpture is 22 ft

Answer:
10) 9x - 2° = 5x + 54° (corresponding angles are equal)
9x - 5x = 54 + 2
4x = 56
x = 56/4
x = 14°
10y + 6° = 9x - 2° (linear pair)
10y + 6° = 9(14)° - 2°
10y + 6° = 126° - 2°
10y + 6° = 124°
10y = 124° - 6°
10y = 118
y = 118/10

Carol gets paid $10 per hour to work as a lifeguard this weekend she worked on both Saturday and Sunday she made a total of $80 girl worked for five hours on Saturday for how many hours did she work on Sunday
Answer:
3 hours
Step-by-step explanation:
Given
[tex]Earnings = \$10[/tex] per hour
[tex]Total\ Earnings = \$80[/tex]
Required
Determine the number of hours worked on Sunday
If she works for 5 hours on Saturday, then her Saturday earnings is:
[tex]Saturday\ Earnings= \$10 * 5[/tex]
[tex]Saturday\ Earnings= \$50[/tex]
Her earnings on Sunday is Total Earnings - Saturday Earnings. So, we have:
[tex]Sunday\ Earnings = Total\ Earnings - Saturday\ Earnings[/tex]
[tex]Sunday\ Earnings = \$80 - \$50[/tex]
[tex]Sunday\ Earnings = \$30[/tex]
Number of hours worked is calculated by dividing earnings by earnings per hour.
So:
[tex]Hours = \frac{\$30}{\$10}[/tex]
[tex]Hours = 3[/tex]
Hence, she worked for 3 hour

Which of the following inequalities are correct?
Some of the numbers involved are shown on the number line below.
Answer:
Only C is correct
Step-by-step explanation:
59 is bigger than -59 not smaller so A is incorrect
0 is smaller than 76 not bigger do B is also incorrect
-76 is smaller than -59 according to number line so option C is correct
Answer:
Only C is correct because -59 would be closer to the 0 that the - 76. So therefore -59 is bigger than -76.

Which inequality represents the following situation:
Hats are $16 each and Joe has no more than $80 to spend. How many hats can he purchase?
80x ≥ 16
80x ≤ 16
16x ≥ 80
16x ≤ 80
Answer:
16x <= 80
It's D
16x= 16$ for each hat
80= the most he can spend
In context: Each hat cost 16$ and the most he can spend is 80, nothing more than that.

If a 30 foot ladder is positioned so that the bottom of the ladder is 1/4 of its length away from the wall, what angle does the ladder make with the ground
Answer:
[tex]75.52^\circ[/tex]
Step-by-step explanation:
Given that:
The length of the ladder = 30 ft
Distance between bottom of ladder and wall = [tex]\frac{1}{4}^{th}[/tex] of its length
To find:
Angle made between the ladder and ground = ?
Solution:
This situation can be compared with a right angled [tex]\triangle ABC[/tex] as shown in the attached image in the answer area.
Side AC being the hypotenuse has the ladder along it.
AB is the wall.
BC is the distance between the wall and foot of ladder.
Formula for cosine trigonometric ratio:
[tex]cos\theta = \dfrac{Base}{Hypotenuse}[/tex]
In [tex]\triangle ABC[/tex]:
[tex]cosC=\dfrac{BC}{AC}[/tex]
Putting the values:
[tex]BC=\dfrac{AC}{4}[/tex]
[tex]cosC=\dfrac{\frac{AC}4}{AC}\\\Rightarrow cos C = \dfrac{1}{4}\\\Rightarrow \angle C = cos^{-1}(0.25)\\\Rightarrow \angle C =\bold{75.52^\circ}[/tex]
Nathaniel participated in an 18-mile race. He ran 1 2 mile in 1 6 hour. If he ran the entire race at the same pace, how long, in hours, will it take Nathaniel to finish the race?
Answer:
24 hours
Step-by-step explanation:
set up a ratio:
12 miles = 16 hours
------------- ------------
18 miles = x hours
cross multiply
12m * x = 16h * 18 m
solve for x
x=16h * 18m / 12m = 24 hours

A group of friends were working on a student film. They spent all their budget on costumes and equipment. They spent $396 on costumes, and 45% of the total budget on equipment. What was the total budget for their student film?
Answer:
The total budget for their student film was $720.
Step-by-step explanation:
From the information given, you know that they spent all their budget on costumes and equipment and that they spent 45% of the total budget on equipment. From this, you could inferred that in order to find the percentage they spent on costumes you have to subtract 45% from 100% that would indicate the total amount spent:
100%-45%=55%
According to this, you know that they spent 55% of the total budget on costumes and the statement says that the amount was $396. With this information, you can use a rule of three to find the amount that represents 100%:
396 → 55%
x ← 100%
x=(396*100)/55=720
The answer is that the total budget for their student film was $720.

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)
Answer:
r = 13
Step-by-step explanation:
The first step is to find b from y=mx=b using m=4/3 and (-4,8)
[tex]8=\frac{4}{3}(-4)+b[/tex]
After solving the equation, b will equal -16/3 making the final equation be
[tex]y=\frac{4}{3} x-\frac{16}{3}[/tex]
Using the equation, you can solve for r.
[tex]12=\frac{4}{3} x-\frac{16}{3}[/tex]
This will bring the answer being r = 13
