Answer:

There are 25 students in the class.

Step-by-step explanation:

In order to find the number of students in the class, you can add the number of data points together. Because the name of each person will only be recorded once and only to one data value, that means by adding the total number of data points collected, you can find out the number of students in the sixth-grade class. There are three data points on 3, two data points on 4, five data points on 5, eight data points on 6, two data points on 7, one data point on 8, and four data points on 9, this means the total number of students will be 3 + 2 + 5 + 8 + 2 + 1 + 4 = 25 students, so this will be your answer.

Answer:

Problem: Jamie was driving for 24 miles in the first hour and 36 miles is the second hour. But, she stopped at a gas station 1/4 of the total drive. Find how far the gas station is from her start.

Answer:

24 + 36 = 50

50 * 1/4 = 50/4

50/4 = 12.5

Explanation: The gas station is 12.5 miles from her start to a 50 mile journey. The gas station was 1/4 of the total drive which was 50 miles. 1/4 of 50 is 12.5

You can get this by creating right triangles with the adjacent side as 20 and using the angles given. You can then find the opposite sides using tangents and then simply add them together.

ANSWER ALL (a-d) FOR 30 POINTS - EASY

Part a.

The perimeter formula is: P = 2w + 2L

Your answer for part A is P = 2w + 2L

Part b.

They tell us in part b, that:
w = 6L + 20

Substitute that into what we got for part a.

P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40

Your answer for partb is P = 14L + 40

Part c.

So we take what we got from part b, and solve for L.

P = 14L + 40
14L = P - 40

$L = \boxed{\frac{P-40}{14}}$

That is your answer for part 3 ^

part d.

Plug in w = 32 into what we first got in part b.

w = 6L + 20
32 = 6L + 20
6L = 12

L = 2

Your answer for part d is L = 2
