One way in which you could do this problem quickly and accurately would be to mult. both sides by a^3, to elim. the fraction:
a^n = a^9 * a^3 = a^(9+3) = a^12. Thus, n = 12.
Answer:
128 degrees
Step-by-step explanation:
38+90=128
Answer:
36 ft.
Step-by-step explanation:
The given perimeter of triangle EDF is 12, in which the hypotenuse is 5. This means that it is a 3-4-5 triangle, meaning that ED = 3, DF = 4, EF = 5.
It is given that BC (the other triangle's hypotenuse) is 15. This means that the left triangle is to the scale factor of 3 of triangle EDF. Therefore, multiply 3 to all sides measurements, and then add all the sides to get the perimeter.
Hypotenuse: 5 x 3 = 15
Leg 1: 4 x 3 = 12
Leg 2: 3 x 3 = 9
Perimeter: 15 + 12 + 9 = 36
36 ft. is your answer.

Jan used 72 grams of tea leaves to make tea.
Square Root of 8 to the nearest tenth, means to calculate the square root of 8 where the answer should only have one number after the decimal point.
Here are step-by-step instructions for how to get the square root of 8 to the nearest tenth:
Step 1: Calculate
We calculate the square root of 8 to be:
√8 = 2.82842712474619
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
2.82
Step 3: Round
Round 2.82 so you only have one digit after the decimal point to get the answer:
2.8
To check that the answer is correct, use your calculator to confirm that 2.82 is about 8.
