Answer:
25
Step-by-step explanation:
3877 divided by 36 is 107.69. That means each person could get 107 masks (always round down in these problems)
36 time 107 is 3852, and 3877 minus 3852 is 25. This is how many will be left over.
0.064 is 0.4 to the third power
Answer:
44m
Step-by-step explanation:
area of a trapezoid = (a+b)* h/2
since the distance between two parallel sides is 15, that would be your height
plug everything in and you get:
480 = (20 + b) *15/2
b = 44
Step-by-step explanation:
On Monday maggie ran n miles.
On Tuesday, she she ran 90% of the number of miles that she ran on Monday i.e 
.
On Wednesday, she ran 50% of the number of miles that she ran on Tuesday i.e. 
First expression : n+0.9n = 1.9 n
Second expression : n + 0.9 n + 0.45 n = 2.35 n
Hence, this is the required solution.
Answer:
33
Step-by-step explanation:
first you set up the problem, supplementary angles equal 180 degrees so the equation should look like, 4x+x+15=180. then you solve from there by combining like terms and you should get x equal to 33
