Answer:

B. 2:1, for every two yellow fish there is one orange fish

Step-by-step explanation:

So you have 6 yellow fish and 3 orange fish.

You can divide both these values by 3 to get:

2 yellow fish: 1 orange fish

Therefore, the simplified version of the ratio is 2:1

In context this means for every 2 yellow fish there is 1 orange fish.

The answer is then B.

I hope this helps!!

aniked [119]

Answer: 600 bushels of 10% alcohol content and 400 bushels of 15% alcohol content.

Step-by-step explanation:

Let we add x quantity of 10% of alcohol content and y quantity of 15% alcohol content for making 12% of alcohol content mixture.

Then according to the question, 10% of x + 15 % of y = 12% of 1000

⇒ 0.1x + 0.15y = 120

⇒ 10x + 15y = 1200

⇒ 2x +3y = 2400 -------- (1)

And, x + y = 1000

⇒ 2x + 2y = 2000 ---------(2)

Equation 1) - equation 2)

We get y = 400

By putting the value of y in equation 1),

⇒2x + 1200 = 2400

⇒ 2x = 1200

⇒ x = 600

Thus, he needs to mix 600 bushel of 10% of alcohol content with 400 bushels of 12% of alcohol content for getting 1000 bushels of 12% of alcohol content.

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6

abruzzese [7]

Answer:

The largest number of pyramids she can make from 20 bars of chocolate is:

A. 180

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

Volume of the bars = 6 in^3 * 20
Volume of the bars = 120 in^3

Now, you must find the volume of each pyramid, using the next formula:

Volume of a pyramid = 1/3 B * h

Where:

B = area of the square base.

h = height of the pyramid.

How these values are given in the problem, we only replace the values in the formula:

Area of a pyramid = 1/3 (1 in^2) * 2 in
Area of a pyramid = 2/3 in^3

Finally, we divide the volume of the bars in the volume of each pyramid:

Total number of pyramids = 120 in^3 / 2/3 in^3
Total number of pyramids = 180

The measure of an angle is 8 times the measure of its complement. tina writes an equation and finds the correct measure of each

pogonyaev

One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)

With all this information, you should have the equation:

n + 8n = 90

To solve, combine like terms to get:

9n = 90

Divide by 9 on both sides to isolate the variable n.

n = 10

Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
