If you use your subtraction right when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like
79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer
hope i helped;)
Answer:
2. 1 / a^2
3, 1
4. - 1
Step-by-step explanation:
Formulas : -
x^y / x^z = x^( y - z )
x^-y = 1 / x^y
x^y / x^y = 1
2.
a^2 / a^4
= a^( 2 - 4 )
= a^-2
= 1 / a^2
3.
m^6 / m^6 = 1
4.
- 8^4 / 8^4
= - 1 x 8^4 / 7^4
= - 1
Answer:
585 miles
Step-by-step explanation:
Basically since he drove 715 miles in 11 hours you would have to divide the 2 numbers then you get 63.
63 is the rate so then you multiply by 9 hours then that's your miles.
585 miles
To find the volume, you would use the formula V=1/3 pi times radius squared times the height. So, you would multiply 1/3 x 3.14 x 5.62^2 x 7.5. This equals approximately 248 cubic inches.
Answer:
32.5%
Step-by-step explanation:
first we will have to calculate how much miles the car traveled, to do that we will multiply the speed by hour long the car was traveling for which is
65*3=195
During those 195 miles the car used 1 gallon for every 30 miles which means it used 6.5 gallons of its tank
195/30=6.5
6.5 gallons is 32.5% of 20 gallons
6.5/20=0.325
0.325 * 100 = 32.5%
