D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
Step-by-step explanation:
r+(−8)=10
r - 8 = 10
r = 10 + 8
r = 18
(substract 8 from 1 side and add it to the other side )
The answer is A. Both collect weather data.
Answer B is false, Balloons generally deconstruct, Satellites do not as they are meant to orbit way past the stratosphere.
Answer C is false, Only satellites can go past the exosphere.
D. Neither of them have any sort of impact on the weather.
