Every week Kabore gets paid $100 plus 5% of his sales. How much does he need to sell if he wants to make $700 this week?
sveta [45]

Answer:

$12,000

Step-by-step explanation:

Kabore wants to make $700 this week. We can subtract 100 from that amount because his base pay is $100.

700 - 100 = 600

This leaves us with 600. Kabore has to make $600 from his sales. However, he only gets paid 5% of his sales. So, 600 is worth 5% of his sales. This can be represented in an equation, where x represents his sales and 0.05 is 5% in decimal form:

\frac{600}{x} = 0.05

Multiply both sides of the equation by x to isolate it on one side:

600 = 0.05x

Divide both sides by 0.05 to find the value of x:

12000 = x

Kabore needs to sell $12,000 worth of product if he wants to make $700 this week.

Hope this helps :)

Jamal will slice a right circular cylinder into to congruent pieces. Which two-dimensional plane section could result from the s
Debora [2.8K]

Answer:

1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Step-by-step explanation:

Given: Jamal Sliced aright circular cylinder into congruent pieces.

To find: Shape of Two-Dimensional plane section obtained after slicing.

We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.

By doing this we get small pieces of cylinders of equal height and equal radius.

Base and top remains same that is circular in shape.

Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus  -∞ < x < +∞

What is the value of y?
Fiesta28 [93]

Answer:

y = 126.43

Step-by-step explanation:

Essentially what you have is the Cosine(50)

Cos(50) = adjacent / hypotenuse

adjacent = 122

hypotenuse = ?? = y

Solve

Cos(50) = 122/y         Multiply both sides by y

y*cos(50) = 122         Divide by cos(50)

y = 122 / cos(50)       Find the value of cos(50)

y = 122 / 0.96497     Divide

y = 126.43
