Molodets [167]

Answer: I think that it is 32

Step-by-step explanation: I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

If cot(theta)= 4/3, find csc(theta) (Picture provided)

kozerog [31]

Answer:

Step-by-step explanation:

If $\cot \theta=\dfrac{4}{3},$ then we can consider right triangle with adjacent leg 4 un. and opposite leg 3 un.. By the Pythagorean theorem,

$\text{hypotenuse}^2=\text{adjacent leg}^2+\text{opposite leg}^2,\\ \\\text{hypotenuse}^2=4^2+3^2,\\ \\\text{hypotenuse}^2=16+9,\\ \\\text{hypotenuse}^2=25,\\ \\\text{hypotenuse}=5\ un.$

So,

$\csc \theta=\dfrac{\text{hypotenuse}}{\text{opposite leg}}=\dfrac{5}{3}.$

What is the range of 8,9,9,8,8,5,8

NISA [10]

Answer:

The range is 4

Step-by-step explanation:

To find the range, you subtract the lowest number from the highest number.

Example: If the set was: 1, 2, 6, 6, 8, 10

What is the highest number: 10

What is the lowest number: 1

You will do this -> 10 - 1 = 9

Problem: 8, 9, 9, 8, 8, 5, 8

What is the highest number: 9

What is the lowest number: 5
