Charles decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 10 feet long. Then he holds a 12-inch
ruler perpendicular to the ground and finds that it casts a 4-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 4.8 ft d. 120 ft
Answer:
C. 30 ft.
Step-by-step explanation:
10 = x
12 = 4
Divide by 4
1inch shadow = 3 inches height
1 inch of a shadow is 3 inches
10 feet is 120 inches
120 * 3
360 inches height = 30 ft

1 yard in 6 minutes
Question 1
Part A
Find the unit rate.
The unit rate in feet per second is 1/120 feet/sec.
Given that, 1 yard in 6 minutes.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
We know that 1 yard=3 feet and 1 minute = 60 seconds
Now, 6 minutes = 360
So, unit rate is 3/360
= 1/120 feet/sec
Therefore, the unit rate in feet per second is 1/120 feet/sec.

A number line going from negative 12 to negative 4. A closed circle is at negative 9. Everything to the left of the circle is shaded.
Is his graph correct? Explain why or why not.
Answer:
Sample Response: No, Jude’s graph is incorrect. The inequality symbol is “less than,” so -9 is not included. He should have used an open circle on -9.

2. 2.9e-33 in scientific notation
Step-by-step explanation:
4×10^22

the "e" basically represents 10 raised to some power. that power is the number to the right of it. in this case, that's to the power of 22 and -33, respectively
Ross has a model truck. It has a scale of 1 inch for every 32 inches on a real-sized truck. He wants to build a garage for the model at the same scale.
Given that the garage for a real-sized truck is 12 feet wide, how wide should his model garage be?
Answer in decimal form: 4.5 inches
Answer as a mixed number = 4 & 1/2 inches
========================================================
Explanation:
" It has a scale of 1 inch for every 32 inches on a real-sized truck" means the the scale is 1:32
Put another way, the real life width is 32 times greater than the scale model.
So we can form the equation
y = 32x
where x is the scale model width and y is the actual real life width.
---------
The garage in the real world is 12 feet wide, or 12*12 = 144 inches wide.
Plug y = 144 into the equation and solve for x
y = 32x
32x = y
32x = 144
x = 144/32
x = 4.5
His scale model garage must be 4.5 inches wide
4.5 inches = 4 & 1/2 inches = 4 and a half inches
Answer:
4.5 inches
Step-by-step explanation:
First, convert all measurements to the mase units
12 feet -> 144 in
Now, we will identify what 144 inches would be as a model scale. We will do so by dividing 144/32 since 32inches equals 1 model scale inch.
144/32= 4.5
therefore, the garage will be 4.5 inches as a model scale.

Three out of five people surveyed said that Shrek 2 is better than Shrek 3 and Shrek 4. If a total of 560 people are surveyed, how many would you expect to agree that Shrek 2 is better?
Answer:
Shrek 2 IS better than the other 2 because THE OTHER TWO HAS NO PLOT!!
Answer:
336
Step-by-step explanation:
To find the answer, we will cross multiply.
3 ?
5 560
We will first multiply 3*560.
= 1680
Next, we will divide our previous answer by 5.
1680/5= 336
therefore, you would expect 336/560 people to like Shrek 2 better than 3 and 4.
