An 8-ounce glass of milk contains
300 milligrams of calcium. How many
milligrams of calcium would a 10-ounce
glass of milk contain?

Answers

Answer:375 milligrams of calcium.

Step-by-step explanation:

300/8 = 37.5

37.5 x 10 = 375 milligrams of calcium.

Answer: 375 mg

Step-by-step explanation:

You would do 300/8, which would give 37.5

So 37.5 mg per ounce

Then you multiply by 10 and boom, you got 375 mg in 10 ounces of milk

Think About the Process Which property of exponents do you use to simplify this​ expression? Simplify the expression. 12^8/12^4

Answers

Answer:

12^4 = 20736

Step-by-step explanation:

The property of exponents used to simplify : 12^8/12^4

The division property :

a^x / a^y = a^(x - y)

Therefore ;

12^8/12^4

12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736

Clare said that 4/3 divided by 5/2 is 10/3 She reasoned: 4/3 x 5 equals 20/3 and 20/3 divided by 2 is 10/3 Explain why Clare's answer and reasoning are incorrect. Find the correct quotient.

Answers

Answer: See explanation

Step-by-step explanation:

4/3 ÷ 5/2

To solve this further, the minus sign changes to multiplication and the inverse of 5/2 is written. This will be:

= 4/3 ÷ 5/2

= 4/3 × 2/5

= 8/15

Claire's reasoning is wrong as she didn't multiply by the inverse of the number.

if you stop at random in front of an animal exhibit,What is the probability that you will be looking at monkeys? I put the table chart below

Answer:

step-by-step explanation:

----------------------------------

| animals | percent of animals |

----------------------------------

|    goats    |          16%           |

----------------------------------

|    camels    |          4%           |

----------------------------------

|    giraffes    |          6%            |

----------------------------------

|   birds    |          27%           |

----------------------------------

|   reptiles    |          14%           |

----------------------------------

|   bears    |          16%           |

----------------------------------

( sorry if the table above isnt 100% right or straight ^ )

first you add up all the percents of how much animals are in this exhibit

16 + 4 + 6 + 6 + 1 + 10 + 27 + 14 + 16

= 100 %

then since we are looking for the probability of stopping in front of the monkeys, we take that 100 we got earlier and get the 10% of monkeys from our table

10/100

but since there isnt a 10/100 on the answers we look for something that equals to 10/100 and 1/10 does since you can just times both the 1 and 10 to equal the 10 and 100 you were looking for

1/10

making 1/10 your answer!

=> for that follow these steps ...

=> 224 X 10 + 7

=> 2247/10

so now to get in decimals ..we divide 2247 by 10..

=> 224.7 ...

so here we  got 224 7/10 in its decimal form ...

Step-by-step explanation:

hope that helps :))

Answer:

0.7 or 244.7

Step-by-step explanation:

I don't know if the question number is 224 and you're trying to write 7/10 as a decimal or if the number you're trying to write as a decimal is 224 7/10.

If the number is 7/10 then the decimal form would be 0.7

If the number is 244 7/10 then the decimal form would be 244.7

Applying the inscribed angle theorems, the true statements regarding the given diagram are: B. m∠BCA = 25° C. m∠BOA = 50°

What is the Inscribed Angle Theorems?

The inscribed angle theorems state that:

Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of intercepted arc = measure of central angle.

∠BCA is an inscribed angle.

m(AB) is the intercepted arc = 50°

∠BOA is the central angle

m∠BCA = 1/2(m(AB) = 1/2(50) = 25°

m∠BOA = m(AB) = 50°

The true statements are:

m∠BCA = 25°

m∠BOA = 50°
