pls help meeeee

A customer purchased x gallons of gas for $2.98 each. The customer gives the cashier $20.00 and gets $2.12 in return.

How many gallons of gas did the customer buy?

Answer: each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5, 6, and 7, then the fourth number is 18 because 5 + 6 + 7 = 18 and the fifth number is 31 because 6 + 7 + 18 = 31.

Answer:

9:6

Because he collected 9 coins in total, and 6 from friends, so this would be the right ratio.

Answer:

S(A) = 306 in²

Step-by-step explanation:

The surface area of a rectangular prism can be found using the following equation:

SA(rectangular prism) = 2(wl + hl + hw)

Note:

w = width = 6

h = height = 12

l = length = 4.5

Plug in the corresponding numbers to the corresponding variables:

SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))

SA(rectangular prism) = 2((27) + (54) + (72))

SA(rectangular prism) = 2(27 + 54 + 72)

SA(rectangular prism) = 2(153)

SA(rectangular prism = 306

S(A) = 306 in²

Answer:

4 hours

Step-by-step explanation:

If the train travels at ~80 kilometers per hour, you just divide the total distance (in this case, 320 kilometers) by the speed traveled (80 kilometers). 320/80 = 4 hours.

Answer:

Equal to

Step-by-step explanation:

Hello!

Let's simplify the left side:

Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.

Let's simplfy the right side:

Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.

So the inequality is 9 _ 9

Therefore the sign should be "=" as 9 is equal to 9.

Answer:

Answer:

Your answer is: 3:2

Step-by-step explanation:

You can see this because there are 3 black circles shown, and 2 white circles.

Since it goes from black to white you first do black which is 3, then to white which is 2.

Meaning you answer is:

i have no idea how i got this answer but yeah i just did math

Mixed Number:

[tex]5\frac{1}{2}[/tex] or 5 1/2

Improper fraction:

2x5+1=11

[tex]\frac{11}{2}[/tex] or 11/2

Decimal:

5.5

5.5 because 5 is whole number, and then, 5 tenths because 5 is half of 10.

Percent:

1 whole = 100%

100% x 5 = 500%

500% + 50% (1/2) = 550%

550%

Answer:

We are given an area and three different widths and we need to determine the corresponding length and perimeter.  

The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards.  This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.

The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards.  This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.

The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10.  This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.

Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

Answer:

The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.

We have given that,

There are 26-second graders, 24 third graders, and 30 fourth graders.

What is the expression?

An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.

The amount of kazoos needed is 1 for every student

26 + 24 + 30

Since 8 come in each box, you divide by 8  

To get your answer of (26 + 24 + 30) ÷ 8.

first one:

The surface area of a pyramid can be found using the formula:

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

Since the side lengths of the base are equal, the perimeter of the base is:

Perimeter of Base = 4 x Side Length

Perimeter of Base = 4 x 9 = 36 feet

To find the slant height, we can use the Pythagorean theorem:

Slant Height^2 = Height^2 + (1/2 x Side Length)^2

Slant Height^2 = 12^2 + (1/2 x 9)^2

Slant Height^2 = 144 + 20.25

Slant Height^2 = 164.25

Slant Height = 12.81 feet

The base area can be found using the formula for the area of a square:

Base Area = Side Length^2

Base Area = 9^2 = 81 square feet

Plugging in the values into the formula for surface area:

Surface Area = (1/2) x 36 x 12.81 + 81

Surface Area = 218.16 square feet

So the surface area of the pyramid is 218.16 square feet.

second one:

The surface area of a pyramid can be found using the formula:

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

Since the side lengths of the base are equal, the perimeter of the base is:

Perimeter of Base = 4 x Side Length

Perimeter of Base = 4 x 8 = 32 meters

To find the slant height, we can use the Pythagorean theorem:

Slant Height^2 = Height^2 + (1/2 x (Side Length1 + Side Length2))^2

Slant Height^2 = 3.5^2 + (1/2 x (8 + 4))^2

Slant Height^2 = 12.25 + 36

Slant Height^2 = 48.25

Slant Height = 6.94 meters

The base area can be found using the formula for the area of a square:

Base Area = Side Length^2

Base Area = 8^2 = 64 square meters

Plugging in the values into the formula for surface area:

Surface Area = (1/2) x 32 x 6.94 + 64

Surface Area = 107.52 square meters

So the surface area of the pyramid is 107.52 square meters.

Answer:

59°

Step-by-step explanation:

The total of all the angles in a triangle should amount to 180°. So:

64° + 57° = 121°

180° - 121° = 59°

Answer:

(-5,7)- Quadrant 2

(8 1/2,-4)- Quadrant 4

(0,5)-y axis

Step-by-step explanation:

Step 1:  Determine where the point lies

(-5, 7) has a negative x value which means that it's either in the second or third quadrant.  Now looking at the y value and it being positive we know that we are in the second quadrant.

(8.5, -4) has a positive x value which means that it's either in the first or fourth quadrant.  Now looking at the y value and it being negative we know that we are in the fourth quadrant.

(0, 5) has a x value of 0 which means that our point lies on the y-axis.

Answer:

x = 10

Step-by-step explanation:

Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.

For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.

First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.

68 ÷ 40 = 1.7

Now that we have the scale factor (1.7) we can now find x.

The similer side D'F' = 17 and DF = x.

We are gonna use the scale factor to divide D'F' to find DF.

17 ÷ 1.7 = 10

Therefore x is 10

Answer:

The answer is 4

[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]

Turn the equation into a simpler form

[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]

[tex]s = \sqrt{\frac{64}{5-1} }[/tex]

[tex]s = \sqrt{\frac{64}{4} }[/tex]

[tex]s = \sqrt{16}[/tex]

That said, we know the square root of 16 is 4, so 4 would be your answer.

[tex]s = 4[/tex]
