We are given with the function
v(p) = 12.3 √(1134 - 3p)
We are asked to find the air pressure when the velocity is 49.3 m/s
Substituting this to v(p)
49.3 = 12.3 √(1134 - 3p)
49.3/12.3 = √(1134 - 3p)
4.01 = √(1134 - 3p)
4.01² = √(1134 - 3p)²
16.07 = 1134 - 3p
3p = 1134 - 16.07
3p = 1117.92
p = 1117.92/3
p = 372.64 millibars
Answer:
28/3 or 9 1/3 pounds
Step-by-step explanation:
Let's set up a proportion using the following setup:
pounds/loaves=pounds/loaves
We know that 7 pounds of flour is needed for 3 loaves. We don't know how many pounds are needed for 4 loaves, therefore we can say x pounds are needed for 4 loaves.
7 pounds/ 3 loaves= x pounds/ 4 loaves
7/3=x/4
We want to find out what x (flour needed for 4 loaves) is. We have to get x by itself.
x is being divided by 4. We need to perform the inverse operation. The opposite of division is multiplication. Therefore, we should multiply both sides of the equation by 4.
4*(7/3)=(x/4)*4
4*7/3=x
9.333333=x
x=9.33 or 28/3 or 9 1/3
It will take 28/3 or 9 1/3 pounds of flour to make 4 loaves of bread.
Answer:
v/lh = w
Step-by-step explanation:
Divide Both Sides by the length and height to isolate width.
Answer:
8 yards
Step-by-step explanation:
first make the fraction improper so 20/9 times 18/5 equals 8
