Answer:

<em>height (h) = 15</em>

Step-by-step explanation:

To figure this out, we use the formula <em>2 · </em>\frac{A}{a + b}, where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get <em>2 · </em>\frac{390}{23 + 29}, which equals 15.

1. Give an example of a repeating decimal where two digits repeat. Explain why your number is a rational number.
zzz [600]

1. A repeating decimal is a decimal number that eventually takes on a repeating pattern of digits after its decimal point that will continue forever. For example, 17.(23)=17.23232323232323....


2. A decimal number that has digits that do not go on forever is called terminating decimal. Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0, then you have a terminating decimal. Otherwise, the remainders will begin to repeat after some point, and you have a repeating decimal.


3. Repeating decimal between 0 and 1: 0.(987)=0.987987987987...

Terminating number between 0 and 1: 0.987

0.(987) >0.987.


4. When dividing 1 by 6 you can get 0.1666666666...=0.1(6).

crimeas [40]

Answer:The larger of two numbers is 8 more than 4 times the smaller if the larger number is increased by four times the smaller the result is 40. From this statement, we can calculate the values of the numbers where you get the value of the larger number to be 24 and that of the smaller number to be 4.
