Answer: <u>It's in the photo.</u>
Step-by-step explanation:
<u>1.</u> 7^8 divided by 7^8 would be 1.
<u>2.</u> 2^-2 would be 0.25. 2^-3 would be 0.125. Multiplied together would be 0.03125.
3. 5^-10 is 1.024e-7
. 5^-15 is 4.096e-9. Simplified would be 0.4.
<u>4.</u> 4^2 is 16. 4^-1 is 0.25. Multiplied together would be 4.

Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.
Answer:
70
Step-by-step explanation: The sum of all interior angles in a triangle equal 180 degrees. Your problem already shows an angle of 90 degrees ( right angle) and an angle of 20 degrees.
180-90-20=70
