How can you quickly calculate 20 percent of any bill amount?

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.

Find the volume V of the cone

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

Your cell phone company started a rewards club. For every three texts sent, you get 1515 points. You need 18001800 points for a prize. How many texts do you need to send to get that prize?

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

Over the last 12 month, Petco has lost a total of $1824.00 due to shoplifting. Write and solve an equation that shows how much money Petco lost each month. ( Since they have lost the money, remember that you need to use negative integers to represent the situation correctly.)

Take y=mx+b  
let x=years and 
y=lost money

then divide 1824 by 12 = 152
and since it is a loss make it into -152
and insert it for m as the constant rate of loss per month
your answer should be y=-152x.
if the store has a starting amount of money plug that into b.

Find the area of the shaded portion of the diagram (use 3.14 for p).A)220.16 square yardsB)6.88 square yardsC)55.04 square yardsD)13.76 square yards

Get the area of the circle. Use this formula: 
Area =  \pi * 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.

Help please will mark brainliest answer!!! ASAP!!! What is the final balance for an account starting with $3000 at 2.5% interest compounded annually for 4 years? A = P(1 + r)t

A = P(1+r)^t  where P is the principal (starting) amount, r is the rate of interest, and t is time. Knowing this, plug in your values:

A = 3,000(1+0.025)^4 < this is what your equation should look like. Once you enter this into a calculator, you should get an answer of $3,311.438672. Round, and you'll be finished.

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

Consider the vector v=(-7,8). What is the angle between v=(-7,8) and the positive x-axis? Part 1: Use the formula v1 x v2=|v1||v2|cos theta to find the cosine of the angle between the two vectors (-7,8) and (1,0).

(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

Find the area and peri19.6 ft13 ftA

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 ( :
