Answer:
it has to be a fraction and this is really hard try looking at a video about this on go ogle
Step-by-step explanation:
First make an inequality to solve for x
(x + 45) + [(x + 45) - 30] + [2x + (x + 45)] = 180
x = 15
now plug x back into each equation and solve
first angle = 60°
second angle = 30°
third angle = 90°
Answer:
765
Step-by-step explanation:
Craig picks 4 times 459 apples, or 1836 apples. The total number Lori and Craig picked is ...
total apples = 459 +1836 = 2295
Each of the three equal groups will have 1/3 this number of apples, so will have ...
1/3 × 2295 = 765 . . . apples
There are 765 apples in each group.
V = A*h / 3
A = 5*12 / 2 = 60 / 2 = 30 m²
h = 9 m
________________
V = 30*9 / 3
V = 10*9
V = 90 m³
