Answer:
b. 45
Step-by-step explanation:
895 ÷ 19 = 47.1
47.1 rounded is 50, but since there is no 50 option, we'll just round it down to 45.

another way:
round 895 (900) and 19 (20)
divide:
895 ÷ 20 = 45
you'll get 45 either way :)
Answer:
96
Step-by-step explanation:
We will use the order of operations to solve the equation
7×8+1×40
multiplication before addition, so we do this first:
7×8=56
We change the equation to this:
56+1×40
Then we multiply:
1×40=40
We change the equation to this:
56+40
Then we add to solve:
56+40=96
32+48 = 80
Four equivalent expressions are:
40+40 = 80
20+60 = 80
10+70 = 80
30+50 = 80
I would argue that it does due to that if it increased, it's either from a 30% chance that nothing changed or that the teachers did it. Since 100-30=70, there's a 70 percent chance that the teaching effect did work!
360°/60 = 6
25 x 6 = 150°
18 x 6 = 108°
15 x 6 = 90°
2 x 6 = 12°
then draw a pi chart with these angles
