Anita does the same number of jumping jacks each day over a period of several days. On the fifth day, she has completed a total of 325 jumping jacks. By the eighth day, she has completed a total of 520. What value equals the slope of the line of the total number of jumping jacks when graphed against the day?

Answers

Answer 1

Answer: 65 is the answer. m = slope = delta y / delta x
delta y = 520 - 325
delta x = 8 - 5

Be well.

Answer: 2.64 x 10^(-10) meters

Explanation

Place the decimal point between the first two nonzero digits. We'll place it between the 2 and the 6.

We now have 2.64

The question is: How can we get back to 0.000 000 000 264 again?

We'll need to move the decimal point 10 spaces to the left to get back to the original value.

Therefore, 0.000 000 000 264 = 2.64 x 10^(-10)

The exponent -10 represents "move the decimal point 10 spaces to the left".

Extra info: There are 9 zeros between the decimal point and the "2" in the number 0.000 000 000 264. Take note of the spacing in the value to group up each set of 3 digits.

A rectangular field is 80 meters wide and 125 meters long.Give the length and width of another rectangular field that has the same perimeter but a smaller area.

Answers

Perimeter of the rectangle is 2*(80+125)=410
The rectangle having the biggest area given the same perimeter is a square. So we need to go "the other way" -- find the rectangle with larger side ratio. 200 m and 5 m is a good example.

The area of the first rectangle: $80 m * 125 m =10000 m^2$
The area of the second rectangle : $200 m * 5 m = 1000 m^2$ (10 times smaller).

What is the length of the altitude of the equilateral triangle below

Answers

Using Sine.

Sine = Opposite / Hypotenuse

sin 60° = a / (6√3) But sin60° = √3/2

√3/2 = a/(6√3)

Cross multiply

2*a = 6√3 * √3

2a = 6 * √(3*3)

2a = 6*3

a = 6*3/2

a = 3*3 = 9

Option E.

Which of the following steps could be used as a shortcut method to multiply 12 by 50?A. Divide 12 by 2, then multiply that result by 50
B. Add 12 and 50, then multiply that result by 10
C. Multiply 12 by 100, then divide that result by 2
D. Multiply 12 by 5 and then multiply that result by 100

Answers

We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200. Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have 12 x 50 = (12 x 100)/2 = 1200/2 = 600 Thus, the answer is C.

The answer is C. Multiply 12 by 100, then divide that result by 2.
