Answer:

39 dimes

Explanation:

From the graph:

• Total number of nickels = 9+4+7=20

,

• Total number of dimes = 7+10+9 = 26

The ratio of total nickels to total dimes = 20:26

If the total number of nickels the students donate is increased to 30, we have:

\frac{\text{Total Nickels}}{\text{Total Dime}}\colon\frac{20}{26}=\frac{30}{x}

We then solve for x:

\begin{gathered} 20x=30\times26 \\ x=\frac{30\times26}{20} \\ x=39 \end{gathered}

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.

Is the length of the hypotenuse of a right triangle with legs that mea-
icang [17]
Answer:
Irrational Number

Step-by-step explanation:
So, since it's a right triangle, you can use Pythagorean Theorem to calculate the measure of the hypotenuse.

Pythagorean Theorem says the hypotenuse squared = the sum of the sides squared.

5² + 6² = 25 + 36 = 61

And the square root of 61 is 7.8102496.... and the decimal continues in no distinguishable pattern. Therefore, the length of the hypotenuse is an irrational number.
