In order to find the number of hats, multiply all the choices together, disregarding size:
4 * 4 * 7 <-- 4 styles * 4 stitches * 7 yarns
= 16 * 7 = 112
112 different hats can be made.
d = 5,000 mi the distance between the missiles
v1 = 2,000 mph the rate of the first missile
v2 = 1,000 mph the rate of the second missile
t = 1 min = 1/60 hr
Since distance = speed*time the distance 1 minute before the impact is:
v1t + v2t = t(v1 + v2) = (1/60)(2,000 + 1,000) = 50 miles.
18%. Divide how much they drove already by the total number of miles they need to drive, then convert the decimal into a percent. Hope this helps.
Answer:
52 and 156
Step-by-step explanation:
Set up system of equations: x+y=208, 1/3(x)=y
plug in 1/3(x) for y: x+ 1/3(x) = 208 so 4/3(x) = 208
divide by 4/3 on both sides: x=156
plug x into original equation: 156+y=208
subtract 156 from both sides: y=52
Answer:
Not sure if this is correct but maybe it is 34?
