If you run a mile in 12 minutes, how fast are you running in miles per hour?

butalik [34]

1 mile in 12 minutes
x miles in 60 minutes

$\frac{1}{12} = \frac{x}{60}\\\\12x = 60(1)\\\\x = 5$

You are running at 5 miles per hour.

A survey of people regarding their favorite flavor of ice cream shows 60% prefer chocolate ice cream, 30% prefer vanilla, and 10

aleksley [76]

26 people would prefer vanilla out of 86 people

Step-by-step explanation:

The percentage is calculated by multiplying the quantity with rate of percentage

Given

Total people surveyed = 86

We have to calculate the number of people who prefer vanilla

The percentage of people who prefer vanilla = 30%

So,

$No.\ of\ people\ who\ prefer\ vanilla = 30\%\ of\ 86\\= 0.30 * 86\\= 25.8$

Rounding off to the nearest whole number: 26

So,

26 people would prefer vanilla out of 86 people

Simplify 4(2x^3y^4)^4/2(2x^2y^6)^3. Show your work. Please help ASAP!!

vovikov84 [41]

Answer:

The simplified expression to the given expression is $\frac{4x^6}{y^2}$

Therefore $\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}=\frac{4x^6}{y^2}$

Step-by-step explanation:

Given fractional expression is $\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}$

To simplify the given expression as below :

$\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}$

$=\frac{2(2x^3y^4)^4}{(2x^2y^6)^3}$

$=\frac{2[(2)^4(x^3)^4(y^4)^4]}{(2)^3(x^2)^3(y^6)^3}$ ( using the property $(a^m)^n=a^{mn}$ )

$=\frac{2[(2)^4(x^{12})(y^{16})]}{(2)^3(x^6)(y^{18})}$

$=2[(2)^4(x^{12})(y^{16})](2)^{-3}(x^{-6})(y^{-18})$ ( ( using the property $a^m=\frac{1}{a^{-m}}$ )

$=2[2^{4-3}x^{12-6}y^{16-18}]$ ( using the property $a^m.a^n=a^{m+n}$ )

$=2[2^1x^6y^{-2}]$

$=\frac{4x^6}{y^2}$ ( using the property $a^m=\frac{1}{a^{-m}}$ )

Therefore the simplified expression is $\frac{4x^6}{y^2}$

Therefore $\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}=\frac{4x^6}{y^2}$
