3.) There are 3 brothers. The first brother is twice as old as the second. The second is twice as old as the third.
If the sum of their ages is 28, how old is each brother?

Answers

Answer 1

Answer:

The first brother is 16, the second brother is 8 and the third brother is 4.

Step-by-step explanation:

Since the sum of all the brothers  is 28, that means the cap of how old the oldest can be is 28. I just stated with numbers less then 28 that were dividable by two which means all the numbers had to be. So 16 for the first, 8 for the second and 4 for the youngest is the right answer I hop.

Answers

Question:

A factory uses 1/8 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/4 of a barrel of raisins. How many batches of granola bars did the factory make yesterday?

Answer:

The factory made 2 batches of granola yesterday.

Step-by-step explanation:

Our ratio from the question is given as:

1/8 barrel of raisins = 1 batch of granola

Hence: 1/4 barrel of raisins = x batches of granola.

Cross Multiply

1/8 × x = 1/4 × 1

x = 1/4 ÷ 1/8

x = 1/4 × 8/1

x = 2 batches of granola

Therefore, the factory made 2 batches of granola yesterday

Answers

Answer:

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

Find the volume of the figure in cubic centimeters.

Answers

Answer:

755.16 cm³

Step-by-step explanation:

We can separate this into two parts -- the bottom rectangular prism and the top triangular prism.

The volume of the bottom part is 12*4*14 = 672 cm³

For the triangular prism, we have an equilateral triangle, with sides 4cm, as well as a length of 12cm. We can find the area of the triangle and multiply it by 12 for our answer. The area of an equilateral triangle is [tex]\frac{\sqrt{3} }{4} 4^{2}[/tex], which is approximately 6.83 -- we can multiply that by 12 to get 83.16 cm³

Add these 2 up to get 755.16 cm³ as our answer

The gardener charged $0.50 per plant and $75 to plant all them

Answers

Answer:  The question is The Gardener charged $0.50 per plant and a flat payment of $75. Which function represents this scenario?

The answer is 0.50x-75

The total cost will be the product of the gardener charged and the number of plants. The total cost is $ 37.5

What is multiplication?

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The gardener charged $ 0.50 per plant and $75 to plant all of them.

Let X be the gardener charged and Y be the number of plants.

The total cost will be the product of the gardener charged and the number of plants. That can be written as

Total cost = X × Y

Total cost = 0.50 × 75

Total cost = $ 37.5

Step-by-step explanation:

5x + 16 = - 3x ( add 3x to both sides )

8x + 16 = 0 ( subtract 16 from both sides )

8x = - 16 ( divide both sides by 8 )
