Sumí is making 8 clay pots in art class. 3 are finished. She has 75 minutes left to work and wants to spend an equal amount of time on each remaining pot. Which is the best way to find how many minutes suki should spend on each remaining pot.

Answers

Answer:

Subtract 3 from 8, then divide 75 by 5.

Step-by-step explanation:

First, subtract 3 from 8 since she finished 3 already.

8-3=5

This means that Sumi has 5 more pots to make. Since she has 75 minutes left, and she wants to finish all the pots in the same amount of time, we can divide 75 by 5.

75/5=15

Sumi should finish each pot in 15 minutes.

Select the correct choice.

Answers

Step-by-step explanation:

To find how much 75% we multiply 100 with 75 and divide it with 100

75 × 10 ÷ 100 = 7.5

we need to do same with Noah's money

25 × 30 ÷ 100 = 7.5 Noah is correct, they have same amount.

A circle has a radius of 12.6 cm. What is the exact length of an arc formed by a central angle measuring 100°?

the answer choices are in the picture please help i’ll give brainliest!!

Answers

Answer: Your answer should be 8.5 π

The formula to find the length of an arc is:

m ∘ 360 ∘ 2 π r  

120 /360  2 π ( 12.6 )

120 /360  25.2 π

Simplify  120 /360  to  1 /3  and finish the other simplifying:

1 /3  25.2 π

25.2 /3 π

Since they want the answer expressed by  π ,  8.5π  is the answer.

What two numbers have a sum of -7 and a difference of 14?

Answers

Answer:

The sum of two numbers is 14 and their difference is 10

Step-by-step explanation:

"2 numbers (x and y)

x+y = 14

and x-y + 10

If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20

The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.

Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2

The difference of 12-2=10 and the addition of 12 and 2 equals 14"

hopes this helps

The first number, x, is 3.5. The other number, y, is 10.5.
X+y=-7
X-y=14.
Those are the two equations. If you use the elimination method, and add those two equations together, the resulting equation is 2x=7. That means the first variable is 3.5. So, 3.5-y=-7, so that means y is -10.5. If you plug that in with the other equation then it comes out as true.

Answers

Answer:

The answer is 12.

Step-by-step explanation:

The triangles are similar, meaning that they have the same ratio. To figure out the ratio, you can see that the smaller triangle has a length of 5 for side AB. The corresponding side on the larger triangle, LM, has a length of 10. When you divide 10 by 5, you get 2, meaning that the triangle on the right is 2 times larger than the one on the left.

Now that we know that, we can solve for side AC. To do this, set up an equation for the corresponding sides. Since the larger triangle is 2 times larger, the equation would look like this: 2(x+5) = 3x+3.

That would simplify out to 2x+10 = 3x+3. Subtract 2x from both sides to get the equation 10 = x+3. Finally, subtract 3 from both sides to get 7 = x.

Now you can solve for side AC. Substitute the x in the equation for 7, giving you 7+5. That equals 12, your final answer.

I hope this makes sense! ☺

The answer would be 12
