B) 196 cubic cm or something like that... First you multiply 7x5x14=490... then you divide 490/5 because you're working in fifths and get 98... the white is only two-fifths so you multiply 98 times 2 and get 196
Solution,
-28x^2+35x
take the common,
-7x(4x-5)
The answer is -7x(4x-5)
Here,
If we solve,
-7x(4x-5)
Then, the answer would be:
= -7x*4x+7x*5
= -28x^2+35x
Hope it helps
Good luck on your assignment
7/5 * 5/7y = 7/5 * 6
y = 42/5.
The multiplication property of equality is used.
Answer:
-2 > x < 2
Step-by-step explanation:
Given that:
2x + 6 > 2
Subtracting 6 from both sides:
2x + 6 -6 > 2-6
2x > -4
Dividing by 2 on both sides:
x > -2
For second equation:
5x< 6 + 2x
Subtracting 2x from both sides:
5x - 2x < 6 + 2x -2x
3x < 6
Dividing by 3 on both sides:
x < 2
Result: -2 > x < 2
Answer:
Step-by-step explanation:
<u>Volume of a cylinder:</u>
<u>Container A</u>
- r = 10 ft, h = 11 ft
- V = π*10²*11 = 1100π ft
<u>Container B</u>
- r = 7 ft, h = 19 ft
- V = π*7²*19 = 931π ft²
<u>After pump out the container A has the level of:</u>
<u>Level % in the container A:</u>
- 169π/1100π×100% = 15.4% rounded to the nearest tenth
