Answer 2

Answer:

7.5

Step-by-step explanation:

7.5 is the smallest. 7.51 is bigger by 0.01, 7.501 is bigger by 0.001 and 7.5 with a dot on top means that the number 5 repeats itself indefinately after the comma so it is like if we wrote 7.55555555 and the 5 kept going on forever

help lol! the explanation is on the bottom!!

Answers

Answer:

1 =80

2 =100

3 =80

4 =100

6 = 100

7 =80

8 =100

Step-by-step explanation: since 5 and 7 are the same, if u slide the bottom up to the top, 1 and 3 would be the same as 5 and 7

2,4,6,and 8 are 180-80 which equals 100

Answer:

1, 3, 5, 7 = 80°

2, 4, 6, 8 = 100°

Step-by-step explanation:

1, 3, 5, and 7 are congruent to each other

2, 4, 6 and 8 are congruent to each other

1 + 2 + 3 + 4 = 360°

80° + x + 80° + x = 360°

160° + 2x = 360°

2x = 360° - 160°

2x/2 = 200°

x = 100°

If 30% of students failed their last test, and there were 40 students that took the test, how many students failed?

Answers

Answer:

12.

Step-by-step explanation:

30% of 40 is 12. To calculate x% of a number y, we use the following rule: x% of y = (x / 100) × y.

Olivia uses the work below to determine 55% of 720.

Step 1: 55 percent = 50 percent + 10 percent minus one-half (10 percent)
Step 2: 50% of 720 = 720 divided by 2 = 360
10% of 720 = 720 divided by 10 = 72
One-half (10 percent of 720) = One-half (72) = 31
Step 3: 360 + 72 – 31 = 401

Which explains the error in Olivia’s solution?
Step 1: Olivia used percents that are not equivalent to 55%.
Step 2: Olivia incorrectly determined 50% of 720.
Step 2: Olivia incorrectly determined One-half of 10% of 720.
Step 3: Olivia subtracted One-half of 10% when she should have added.

The area of the September is 336cm is all this model rectangles are exactly the same what is the perimeter of rectangle if the length of one rectangle is 12 CM

Answers

Answer:

Perimeter is 80cm

Step-by-step explanation:

A rectangle's area is calculated by multiplying the length by the width. If we are given the area of the rectangle and the length then we would simply need to solve for the width of the rectangle using the area formula we just mentioned...

A = l * w

336[tex]cm^{2}[/tex] = 12cm * w  ... divide both sides by 12cm

28cm = w

Now we can see that the width of this rectangle is 28cm. To find the perimeter we need to add all four sides together, since we know that a rectangle's opposite sides are the same then we add the length and the width twice to calculate the perimeter (P)

P = 12cm + 12cm + 28cm + 28cm

P = 80cm

How do I find the correct slope on a graph?

Answers

Answer:

To find the slope of a line from a graph, first choose 2 points along the line and write down the X and Y coordinates for each. Next, find the rise by taking the difference between the 2 Y coordinates. If the line slopes up as it moves to the right, the rise will be positive. If it slopes down, the rise will be negative.

Step-by-step explanation:

M=rise/run or y2-y1/x2-x1
