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
Answers
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

Amil took $65.00 to go shopping, and he bought 2 pair of jeans for $27.00 each. How much change will he have? Choose the expression that is a correct translation of the problem.
(2 x 27) - 65
65 – (2 x 27)
65 – (2 + 27)
65 – 2 + 27
Answers
Answer:
B) 65 – (2 x 27)
Step-by-step explanation:
65 is you total, 2 is the amount of jeans and 27 is the individual price of the jeans.
Since you want to know how much is left over, you subtract how much you spent which would be, in this case, the jeans.
You bought 2 jeans, each for 27 dollars so you multiply the two to see how much for both jeans.
Subtract that from the total.
Hope this helps! (^-^)
Answer:
65-(2 x27)
Step-by-step explanation:
You already know that Amil has 65$ so that's the first part.
And then it tells you that he bought 2 pairs of jeans and the price.
So if u multiply how many jeans he got times the price that tells you how much it cost. So it cost 54$
Last but not least you subtract 54$(the price) from 65$(how much money he had) to get the amount of change left over.

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?
Answers
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.

1 yard in 6 minutes
Question 1
Part A
Find the unit rate.
Answers
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.

The event coordinator asks you to determine how many students participated in the
track-and-field day. The total number of students in seventh and eighth grade
combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth-graders. If 4/8 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answers
Answer:
374.125 students. Not sure if you're supposed to round up or down considering you can't have a fraction of a person, but I would round down.
Step-by-step explanation:
(5/8) (584) = 365 seventh graders in total
(3/8) (584) = 219 eighth graders in total
(4/8) (365) = 182.5 seventh graders who participated in track-and-field day
(7/8) (219) = 191.625 eighth graders who participated in track-and-field day
182.5 + 191.625 = 374.125 students in total who participated
Answer:
First, I took 5/8 out of 584 for the seventh graders which came out to 365 seventh graders. Then, I did the same thing with 3/8 and it came out to 219 eighth graders. Then I took out 4/5 out of 365 which resulted as 292. Then I did the same thing for 7/8 and the results came out as 191. So in total 483 students participated in track-and-field day.

The expression in simplified form, obtained from the distributive property of multiplication over addition is; 15·m - 30
What is the distributive property?The distributive property of multiplication over addition states that for numbers, a, b, and c, we get;
a·(b + c) = a·b + a·c
The expression, 5·(3·m - 6) can be simplified by applying the distributive property of multiplication as follows;
5·(3·m - 6) = 5 × 3·m + 5 × (-6) = 15·m - 30
The simplified form of the expression is therefore; 15·m - 30
