Answer:
21
Step-by-step explanation:
84000/4000=84/4=21
X = height of larger cylinder
The ratio of the heights can be cubed to get the ratio of the volumes
(x/5)^3 = 343/125
(x^3)/(5^3) = 343/125
(x^3)/125 = 343/125
x^3 = 343
x = (343)^(1/3)
x = 7
The height of the larger cylinder is 7 feet
295 she spent
y dollars she can spend on other expanses
then 295+x+y=500
implies x+y=205
Answer:
x = - 2√2
x = -2
Step-by-step explanation:
A . 5 + x² = 2 x² +13
5 + x² - 2 x² - 13 = 0
- x² -8 = 0
- x² = 8
x² = -8
x = - √8
x = - 2√2
B . 5 + x³ = 2 x³ + 13
5 + x³- 2 x³ - 13 = 0
- x³ -8 = 0
-x³ = 8
x³ = -8
x = - ∛8
x = -2
Answer:
Question 5: y = - x + 6
Question 6: y = x + 100
Question 7: y = -10x + 45
