A businessman is paid $12 per hour and $10 for each sale he makes. He wants to earn more than $250 in an 10-hour work period. Write an inequality that represents the number of sales, x, the businessman must make in an 10-hour period to earn more than $250.

What is the least number of sales he must make to reach his goal?

Multiply hotly rate by hours worked, he want to work 10’hours so 12 x 10 =120

Add that to number of sales x amount earned per sale: 10s

Now you have 120 + 10s

He wants to earn at least 250:

120 + 10s >= 250

Now solve for a

Subtract 120 from both sides:

10s >= 130

Divide both sides by 10:

S >= 13

Minimum sales need to be 13

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
