First off, if they’re vertical angles, they have to be congruent. So set the equation up as x=4x-30. Then solve and get the answer of x=10. Therefore your angle measure is 10 degrees

3/4 is 60% of what number?

AnnyKZ [126]

If you want to find the whole, you have to start by dividing 100% by 60%, so you can multiply that quotient by 3/4 to find the whole. 100/60=10/6=5/3. That means 5/3*60%=100%, so 3/4*5/3=whole. 3/4*5/3=15/12, and simplify to get 5/4, or 1 1/4. 3/4 is 60% of 1 and 1/4, or 5/4.

According to the chart below, what percentage of Ralph’s expenses are items other than taxes?

pochemuha

Answer:

65%

Explanation:

Please, see attached the chart corresponding to this question.

The chart is a pie chart that shows the percentage composition of the expenses and uses color to identify each item.

The items corresponding to taxes are:

Federal tax: 29%
State tax: 6%

All the other expenses are not taxes.

Add the two items that are taxes: 29% + 6% = 35%.

Hence, the expenses that are not taxes can be calculated by difference:

100% - 35% = 65%.
