Answer:

INSTRUCTION FOLLOWED: write the sum as a mixed number where the fractional number is less than one.

5/5 out of the 7/5 make ONE whole while 2/5 is left over.

The ONE whole is added to nine to make 10 and the remaining 2/5 is also added to the 10 hence 9 7/5 = 10 2/5

Jess can drive 200 miles on 1/2 tank of gas. How far can he drive with 3/4 of a tank?

attashe74 [19]

Answer:

300 miles

Step-by-step explanation:

Since Jess can drive 200 miles on a 1/2 of a tank of gas that must mean he can drive 100 miles with his gas tank only 1/4 full. Since he needs to know how far he can drive with his gas 3/4 of the way full he would just add 200 miles to 100 miles and get 300 miles.

You figure this out by dividing 200 miles by 2 since it is a half way full and you just need to half the amount of miles to get how many miles it is for a fourth of the way full. You would need to find out how much it is for a fourth of the way full since it only says Jess can drive 200 miles on a 1/2 tank of gas. However we need to find out how far he can drive with 3/4 tank of gas. Which you know that you need to find out how much it is for a fourth of a tank of gas or 1/4 since 1/2 is also equal to 2/4 and 1/4 plus 2/4 is equal to 3/4.

I hope this helps! If you need any more further help with this question let me know.

The height of a small rock falling from the top of a 124-ft-tall building with an initial downward velocity of –30 ft/sec is mod

Contact [7]

Answer:

Option 3.

Step-by-step explanation:

The given function is

$h(t)=-16t^2-30t+124$

where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.

It is a downward parabola.

Equate the function equal to 0, to find the time at which the rock touch the ground.

$-16t^2-30t+124=0$

If $ax^2+bx+c=0$ , the according to the quadratic formula

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

Using quadratic formula, we get

$t=\dfrac{-(-30)\pm \sqrt{(-30)^2-4(124)(-16)}}{2(-16)}$

$t=\dfrac{30+\sqrt{(-30)^2-4(124)(-16)}}{2(-16)},\dfrac{30-\sqrt{(-30)^2-4(124)(-16)}}{2(-16)}$

$t=-3.875, 2$

Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.

Therefore, the correct option is 3.

Foston is between library and West Quan and is 4 inch away from the library on the map how far is Boston from West qual

Andrews [41]

Boston would be 8 inches away on a map from WQ, because the library is in between Boston and WQ, and the library is 4 inches away from Boston, so, logically, it would be about 4 inches away from WQ, too.

Thus, Boston is 8 inches away from WQ.
