Answer:
3.4 yards cubed
Step-by-step explanation:
Volume is length x width x height
Length 2 4/5, Width 2, Height 3/5 so 2 4/5 x 2 x 3/5
It looks like they want the answer in decimal form, so you can convert the fractions into decimals.
For the length 2 4/5, you divide the 4 by 5 to get a decimal of .8 so now it's 2.8
For the height of 3/5, you divide the 3/5 & get .6
Now it's 2.8 x 2 x .6 = 3.36 yards cubed which could get rounded up to 3.4 yards cubed
Answer:
9.549296
Step-by-step explanation:
30/pi = 9.549296 for diameter
5% sales tax, because the total would be $42 and if you multiply 40 x 0.05 (the equation for tax) you get 2 and that is the amount of tax they charged you
Answer:
<em>Equation: 10t=400</em>
<em>It will take them 40 hours to be 400 miles apart.</em>
Step-by-step explanation:
<u>Constant Speed Motion</u>
If the speed of an object is v, the distance traveled in a time t is:
Ms. Ironperson travels at 50t (not speed, but a distance), and Mr. Thoro travels at 60t. Since the latter travels faster, the distance between them at time t is given by:
To be 400 miles apart, we set the equation:
10t=400
Solving:
t=400/10=40
It will take them 40 hours to be 400 miles apart.
Note: Some assumptions were made in this question:
- The rates are not speeds but distances
- The distances are in miles
