Answer:
The length is 95 m
Step-by-step explanation:
P = 2(l+w) where l is the length and w is the width
342 = 2(l+76)
Divide each side by 2
342/2 = 2/2(l+76)
171= l+76
Subtract 76 from each side
171- 76 = l+76-76
95 = l
Answer:
9 cups of flour
Step-by-step explanation:
Multiply by 3. 8 cups of water multiplied by 3 is 24 cups of water so you do the same to the flour to keep them balanced and ratioed. So 3 cups of flour times 3 is 9 cups of flour. 8:3 is the ratio.
Answer:
c = 43
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin 28 = 20/c
Multiply each side by c
c sin 28 = 20/c *c
c sin 28 = 20
Divide each side by sin 28
c sin 28 /sin 28 = 20/sin 28
c = 42.60108936
To the nearest whole number
c = 43
Answer: V=9651 ft^3
Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.
The radius is the diameter divided by 2, which is 8.
We can put the equation in terms of π by doing π*(8^2*48)=3072π.
Solving this gives us about 9650.972632, which you can round to get 9651.

Answer:
x=0
Step-by-step explanation:
y=-5x -6
10x + 2y = -12
Substitute y into the equation:
10x+2(5x-6)=-12
Use distributive property
10x+10x-12=-12
Add like terms
20x-12=-12
Add 12 to both sides of the equation
20x=0
divide each side by 0
x=0
