1 3/4 miles in twenty minutes

1 answer:

8 0

No instructions? I'll assume you want the unit rate.

4 miles in 36 minutes = 4/36 miles in 1 minute, or 1/9 mile in 1 minute.

1 3/4 mile in 20 minutes? Multiply both figures by 3:

7 miles in 60 minutes, or 7 miles in 1 hour, or 7 mph.

One eighth of Tony's books are mystery books. He has 3mystery books. How many books does tony have in all?

Anit [1.1K]

If one book = 1/8, then you can just multiply it by 3, for the three mystery books. 8x3= 24, so tony has 24 books in all.

Which expression is equal to 5^4 x 5^8 ? A: 5^12 B: 5^4 C: 5^2 D: 5^−4

galben [10]

Something to remember is how to multiply terms with same bases, but different exponents:

$a^b \cdot a^c = a^{(b+c)}$

Essentially, we add the exponents.

Using the information above, we can find our answer:

$5^4 \cdot 5^8 = 5^{(4+8)} = \boxed{5^{12}}$

Our answer is $\boxed{5^{12}}$ , or A.

1. Rewrite the expression. Use an exponent, rather than repeated multiplication. (–4)(–4)

-4^2 is the same as -4*-4

-4*-4=16

-4^2= 16

-4^2 is the exponent.

I hope this helps!
