Don't cry!! You got this! Just take it one step at a time and list your known values:
h = 5 m
r = 5 m
The volume of a cone is V = (1/3)πr^2h
V = (1/3)(3.14)(5)^2(5) = 130.83 m^3
I believe in you! I hope this helps!
Answer:
12
Step-by-step explanation:
4 quest make 1 gallon so 4*3=12
Answer:
Y-intercept: (0,4)
X-intercept: (8,0)
Step-by-step explanation:
equation of the line:
(4,2) (-2,5)
5-2/-2-4
3/-6
-1/2
m = -1/2
point slope form:
y-2=-1/2(x-4)
simplify:
y-2=-1/2x+2
y=-1/2x+4
Y-intercept: (0,4)
X-intercept: (8,0)
Four times the sum of a number and 15 is at least 120
Let ‘x’ represent the number.
"The sum of a number and 15"
This can be written mathematically as x + 15
Given that 4 times this sum is at least 120,
This means that 4 times the sum is greater than or equal to 120
This can be written mathematically as 4(x + 15) >= 120
Solving for x
4(x + 15) >= 120
4x + 60 >= 120
4x >= 120 – 60
4x >= 60
x >= 60/4
x >= 15
x is greater than or equal to 15

Answer:
x = 3
Step-by-step explanation:
2(4-3x) + 5(2x-3) = 20-5x
8 - 6x + 10x - 15 = 20 - 5x
-6x + 10x + 5x = 20 - 8 + 15
9x = 27
x = 3
