Answer:

\frac{-10}{12} ,\frac{-5}{6}

Step-by-step explanation:

Start with:

\frac{-2}{3} × \frac{5}{4}

Multiply your numerators.

(-2)(5)=-10

Now, multiply your denominators.

(3)(4)=12

Let's transfer those numbers into a fraction.

\frac{-10}{12}

You may need to simplify.

Divide by the greatest common factor. In this case, that would be 2.

-10 ÷ 2=-5

12 ÷ 2=6

Put those numbers back into the fraction.

\frac{-5}{6}

If (5^2)p = 5^12, what is the value of p?
mr Goodwill [35]
Divide both sides by 5^2 (which is 25). So p = (5^12)/25. I can't be bothered to plug in into a calculator but be my guest.

german

Answer:

a) 122.5 m ; b) 10 s

Step-by-step explanation:

Just use the given equation and plug in what you know.

d = 4.9t^2

d = 4.9(5^2)

d = 4.9 * 25

d = 122.5 m

b)

d = 4.9t^2

490 = 4.9t^2

100 = t^2

t = 10 s

A tower made of wooden blocks measures​ 114 feet high. Then a block is added that increases the height of the tower by 8 inches.
satela [25.4K]

Answer:

4. 23 in

Step-by-step explanation:

The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.

1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.

Add 8 inches to 15, and you get 23 inches.

<u>The answer is 4. 23 in. </u>
