Answer:

Step-by-step explanation:

We can first solve this by turning this sales tax percentage into a decimal

\(8.6\% = 0.086\%\)

Now that we got that and your first answer of $57.40, we can multiply the two numbers.

\(0.086 \times 57.40 = 4.9364\)

For which pair of points can you use this number line to find the distance?

A number line going from negative 2 to positive 8. Points are at 1 and 7.

C-(–1, –4) and (–4, 7)
D-(–4, –1) and (–4, –7)

Answers

Answer:

b or c wait it is B i am pretty sure

We can use the number line for the pair of points (-4,1) and (-4,7) to find the distance.

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines.

Given that a number line going from negative 2 to positive 8. Points are at 1 and 7.

Remember that the distance between two points (a,b) and (a,c) can be found by calculating the distance between b and c, the second coordinates.

Also, for a pair of points (x,y) and (z,y), we can determine the distance between those two points by calculating the distance between x and z.

Therefore, we need to find pair of point whose form are; (a,b) and (a,c) or (a,b) and (c,b).

In this case of (-4,1) and (-4, 7), and (-4,-1) and (-4,-7).

For the first pair of points, we have the distance between 1 and 7, and, as for the second pair of points, the distance between -1 and -7.

Thus, the answer is (-4,1) and (-4,7).

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

the area of the five squares is 1289.09 square units

the perimeter is 194.6 units

Bruno bought 96 pounds of sugar for his bakery. Every day he used the same amount of sugar to make bakery items. After 10 days, Bruno was left with 15.2 pounds of sugar. On average, how many pounds of sugar did Bruno use each day? (1 point)
a 5.60 pounds b 8.08 pounds c 11.12 pounds d 18.46 pounds

Answers

Answer:

9.6

Step-by-step explanation:

you divide 96 by 10

Answer:

The answer is B

Step-by-step explanation:

The answer is B. Since Bruna used 96 pounds of sugar each day you would have to use the equation 96-x(10 times)=15.2. You would have to plug in each answer to see if it would give you 15.2. I plugged in 5.60 and Bruno was left with too many pounds left over. 11.2 pounds each day would be to low. I then plugged in 8.08 and subtracted by 96 ten times and got the answer 15.2. I hope this helps.

If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?

(step-to-step pls)

Answers

Answer:

Step-by-step explanation:

Step 1 is to find the total number of balls in the pail.

There are 8 balls in total

Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.

Since 4 out of the 8 balls in the pail are green, you can write this as 4/8

The last step is to simplify to get 1/2 which in other terms is 50%.

So the probability of you pulling a green ball is 50%

It’s 50 percent chance of pulling out a green ball.

Terry had 400 inches of ribbon before he cut 20 pieces of ribbon that were each 8 inches long. How many 15-inch pieces can Terry cut from the remaining ribbon?

PLEASE HELP ASAP

A: 14

Answers

Answer:

16 pieces

Step-by-step explanation:

The total length of ribbon cut off from the 20 pieces is 8*20 because each piece is equal to 8. 8*20=160

The amount of ribbon left afterwards is 400-160 which is equal to 240.

We can do 240 divided by 15 to see how many pieces that we can cut. 240/15=16

This is because if you do keep change flip you will have 4/1*4/1 by keeping the four and just changing it into an improper fraction. Changing the division sign into a multiplication sign and then flipping the 1/4 to 4/1. Than your will simplify 4/1*4/1 is 16/1. Than if you simply 16/1 you will get just 16.

This is the same thing but you will make the 1 2/3 into an improper fraction and that is by multiplying the 1 by the denominator (3) and then adding by the numerator. Making you get 5/3 and then using keep change flip you will have 5/3*3/1 making 15/3. Than simplifying into just 5. This is because 15 divided by 3 is equal to three.

Same thing just use keep change flip. Than you have 3/5*5/1 and that is equal to 15/5 making it 3.
