First, convert the percent into a decimal. To do this, simply more the % sign two places to the left and make it into a decimal point.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.

V=πr^2(h/3)

V≈804.25

Since the height is 12, and radius is 8, take the radius and square it. 8 squared equals 64. Now, take the height (12) and divide that by three. This equals 4.

So Volume = Pi times 64 times 4. The answer should be 804.247. Once rounded, you should get 804.25

**Answer:**

**35,648**

**Step-by-step explanation:**

**Given that**

Points scored for sending three texts = 1515

Total points needed to win the prize = 18001800

**We need to find**

Text needed to be sent to win the prize = x= ?

As per given info

3 texts sent give points = 1515

1 text sent give points = 1515/3

**1 text sent give points = 505**

Now we can use the following formula to calculate the total number of texts that need to be sent to win 18001800

Total Number of texts = Total Points needed to win the prize/ Points scored by sending a text

x= 18001800/505

x = 35,647.12 texts

this can be approximated to **35,648** texts to win the prize

QUESTION POSTED AT 31/03/2020 - 10:40 AM

Get the area of the circle. Use this formula:

Area = * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2

Area = 3.14 * 16

Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is

Area = side^2

Area = 8^2

Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, D) 13.76 square yards is the answer to this question.

QUESTION POSTED AT 30/03/2020 - 01:33 AM

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :
