Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7

Answer:

150 $m^2$

Step-by-step explanation:

Each square on a cube is 5 by 5 meters long.

The area of each square is 5 * 5, which is 25 square meters.

There are 6 sides on a square, so multiply 25 by 6, and you will get 150.

Find the slope of the line with x intercept 9 and y intercept of -2

elena-s [515]

Answer:

2/9

Step-by-step explanation:

Find the slope of the line with x intercept 9 and y intercept of -2

Given that the equation of the line is y = mx+b

x intercept occurs when y = 0

The coordinate of x intercept is (9,0)

y intercept occurs at x = 0

The coordinate of y intercept is (0, -2)

Slope m = y2-y1/x2-x1

m = -2-0/0-9

m = -2/-9

m = 2/9

Hence the required slope is 2/9

The waiting time to ride a roller coaster is 20 minutes when 150 people are in line. How long is the waiting time when 240 peopl

laiz [17]

Answer: The waiting time will be 32 minutes when 240 people in line.

Step-by-step explanation:

Let us assume that the waiting time is directly proportional to the number of people in the queue.

Equation of direct proportion between variables x and y : $\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}$

Put $x_1=20,\ y_1=150,\ y_2=150$ to find $x_2$ .

$\dfrac{20}{150}=\dfrac{x_2}{240}\\\\\Rightarrow\ x_2=\dfrac{20}{150}\times240\\\\\Rightarrow\ x_2=32$

Hence, the waiting time will be 32 minutes when 240 people in line.
