The first question:

'is' in mathematics means equal

'of' in mathematics means multiplication

**56% of 25 is 14**.

And the second question:

'is' in mathematics means equal

'of' in mathematics means multiplication

**55% of 20 is 11**.

'is' in mathematics means equal

'of' in mathematics means multiplication

And the second question:

'is' in mathematics means equal

'of' in mathematics means multiplication

You can buy 50 of the cherry candies with all of the 25$ because you do 25 divided by 0.50 and get 50 and then if you would like to check that do 50 x 0.50 and you will still get 25$

The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.

So we know the formula to find the surface area of a sphere (ball) is:

4 x pi x r^2

to find the radius, divide the diameter by 2 to get:

14 / 2 = 7

now we substitute in the values:

4 x pi x 7^2

simplify:

4 x pi x 49

simplify:

12.56 x 49

simplify:

**615.44 inches**

the answer is above in bold

hope it helped :)

QUESTION POSTED AT 22/01/2020 - 02:19 AM

**Answer:**

Option C. 3, -2, -7, -12....

**Step-by-step explanation:**

The sequence is defined recursively using the formula f(n+1) = f(n) - 5

We have to identify the sequence generated by this formula.

B). 1, -5, 25, -125.....

f(n+1) = -5 and f(n) = 1

Therefore - 5 = 1 - 5

⇒ -5 ≠ -4

This sequence is not following the formula.

B). 2, 10, 50, 250.........

f(n+1) = 10 and f(n) = 2

Now we use the formula

10 = 2 - 5

10 ≠ -3

This sequence is not following the formula.

C). 3, -2, -7, -12

f(n+1) = -2 and f(n) = 3

We put this value in the formula

-2 = 3 - 5

-2 = -2

Therefore , the sequence is following the formula.

D). 4, 9, 14, 19........

f(n+1) = 9 and f(n) = 4

9 = 4 - 5

9 ≠ -1

Therefore the formula is not applicable to form this sequence.

Option C. is the answer.

The most cost effective company will be:

25 hours

Painting USA: Fixed Cost: $75; Variable Cost: $25x

Total Cost = 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting: Fixed Cost: $0; Variable Cost: $40x

Total Cost = 40(25) = 1,000

The most cost effective company will be Painting USA whose charges will amount to $700

The cost of painting the house will be the same for both companies if the number of hours required to paint Paul's house is:

Painting USA:

Total Cost: 75 + 25(25) = 75 + 625 = 700

Upscale Home Painting

Total Cost: 40(16.5) = 40 + 660 = 700

We may answer the question above by dividing the expression y² - 10x + 24 with the given factor, y - 4. The division would give an answer of y - 6. Thus,

y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.

y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.

A quadratic equation has the general form of:

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

where h and k represents the vertex, h represent the point in the x axis and k is the point in the y axis. From the choices given, the first step in rewriting the equation is that 6 must be factored from 6x2 + 18x. Which yields to:

**y = 6(x^2 + 3x) + 14**

y=ax² + bx + c
