Volume = length x width x height or V = lwh as a formula if you will.
Let's substitute what we know into the formula:
100 = 4(5)h multiply the 4(5) on the right side
100 = 20h divide both sides of the equation by 20
5 = h
the height of the rectangular box is 5 feet
Answer:
Step-by-step explanation:
Answer: There is only 2 number between 200 and 300 which can exact divide by 6, 8 and 9
When you're adding fractions with two different denominators, the best thing to do is to find a common denominator;
In this case, 4 and 8 are both multiples of 8, and therefore, you've got to double the first fraction.
Doubling the first fraction gives you 2/8 and 3/8. You've then got to add these together, and this gives you 5/8 (as you only add the numerators)
As you're looking for what is left, you have to do 8/8- 5/8 (once again, only subtracting the numerators)
8/8- 5/8= 3/8
Therefore, 3/8 of the muffins are left.
Hope this helps :)
Answer:
Mr Lee: 26000
Mr.Chong: 52000
Step-by-step explanation:
Mr. Lee=x
Mr.Chong=2x
x+2x=78000
3x=78000, then divide
x=26000
2x=x*2=26000*2=52000
r(x) = –x² + 3x
s(x) = 2x + 1
(s – r)(x) is simply the difference of these functions. Subtract r(x) from s(x):
(s - r)(x) = s(x) - r(x)
(s - r)(x) = 2x + 1 - (-x² + 3x)
(s - r)(x) = 2x + 1 + x² - 3x
(s - r)(x) = x² - x + 1
