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
Whoa just a second there.
What is the question ?
Is the question "Find the percent of increase ?"
In that case, the answer is 300% .
Here's why:
The amount of increase is 75.
The amount of increase as a fraction of
the original amount is
75 / 25 = 3.00 .
To change any number to a percent,
move the decimal point 2 places that way ===> .
3.00 = 300% .
______________________________
The question could have been different.
It could have been "What is the amount of the increase ?"
That's 75.
It could have been "How many times larger is 100 than 25 ?"
100 is 4 times as large as 25, and 3 times larger.
It could have been "How many times has 25 been increased ?"
This is a terrible question ... there are a lot of those in schools.
The answer could be "25 was only increased once, by 75."
The answer could be "25 was increased to 4 times its size."
The answer could be "25 was increased by 3 times its size."

i don't know if you still need help, but the answer is x=180-30-30=120 degrees
Answer: If the question is asking for the point of intersection, it’d be (3,1).

Both of the methods below are valid.
Answer: c)[50,60]
Step-by-step explanation:
The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).
We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.
Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.
i.e. about 68% of the heights of students lies between
i.e. about 68% of the heights of students lies between
Here,
i.e. The required interval that contains the middle 68% of the heights. = [50,60]
Hence, the correct answer is c) (50,60)
