Answer: 9%
Step-by-step explanation: as all the marks are out of 100 i suppose
so Ali got 58% at eng and 49% at math
so 58-49=9%
and that is how we get the answer

Answer:
The angle that is supplementary to angle ∠ Z2 is 136°
Step-by-step explanation:
Given as :
∠ Z2 = 44
Let The supplementary to ∠ Z2 = ∠x
∵ For Supplementary angle , measure of Two angles = 180°
Or, ∠x + ∠ Z2 = 180°
Or, ∠x + 44° = 180°
Or, ∠x = 180° - 44°
So, ∠x = 136°
Hence The angle that is supplementary to angle ∠ Z2 is 136° Answer
Answer:
It´s -12
Step-by-step explanation:
Its -12 because the two lengths are the same, so the sum must be the same. -12+25 is 13, so we should get 13 on the top as well. 2*-12 is -24. -24+29 is 5. and 5+8=13. 13 = 13.
Answer:
1200 ft²
Step-by-step explanation:
We assume that we want the total surface area, which includes the curving sides and the flat ends.
1. Curving sides: We are actually finding the area of a flat piece of material whose length is C = 2πr and whose width is the height of the cylinder, h. Then this side area is A = 2πrh. Here, that area is
A = 2π(15 ft)(25 ft) = 750π ft²
2. Ends: The end area is A = πr², and there are two ends.
The total area of the ends is A = 2πr², which here is A = 2π(15 ft)², or
A = 450π ft².
Thus, the total exact surface area of this cylinder is
A = 450π ft² + 750π ft² = 1200 ft²
