Answer:
Katherine: 920
Crystal: 552
Step-by-step explanation:
The total amount earned by each is 1472
The ratio of the earnings is Katherine / Crustal = 5/3
The total number of shares = 5 + 3 = 8
So the proportion for Katherine
5/8 = x / 1472 Cross multiply
8x = 5 * 1472
8x = 7360
x = 7360/8
x = 920
And the proportion for Crystal is
3/8 = x / 1472 Cross multiply
8x = 3 * 1472
8x = 4416
x = 4416 / 8
x = 552
Box:
Length = 6 feet
Width = 5 feet
Hight = 1.2 foot
Volume of the box = LxWxH
Box volume = 6x5x1.2 = 36 cubic feet
The Box holds 36 cubic feet of sand.
While Jodi bought 20 cubic feet of sand
Which means that Jodi is short by:
36 - 20 = 16 cubic feet.
17×19.5=331.5 is the answer if I did it right
Answer:
2a (3-4a)
Step-by-step explanation:
(2a+1)-4a(2a+1)+4a
2a+1-8a²-1+4a
= 2a+4a-8a²
=6a-8a²
= 2a(3-4a)
Elements of N should be like {6,7}
