Karla's traditional hybrid car gets 35% fewer miles per gallon than Jeenie's solar hybrid car. If Jeenie's car gets 60 miles per

gallon, how many miles per gallon does Karla's car get? Calculate Karla's car mileage in two different ways, using two different scale factors (multipliers).

Answer:

39\ miles/gallon

Step-by-step explanation:

Let

x------> Karla's car mileage

1) First way

we know that

100%-35%=65%=65/100=0.65

so

x=0.65(60 miles/gallon)=39 miles/gallon

2) Second way

by proportion

\frac{60}{100} \frac{(miles/gallon)}{\%} =\frac{x}{65} \frac{(miles/gallon)}{\%}\\ \\x=60*65/100\\ \\x=39\ miles/gallon

What is ∛1728. Then multiplied by ∛14903
NeTakaya

Cube root of 1728 is 12 and on multiplying it by cube root of 14903 we get 295.306.

<u>Solution: </u>

Need to calculate \sqrt[3]{1728} and then multiply the result by \sqrt[3]{14903}

Let us first evaluate \sqrt[3]{1728}

\Rightarrow \sqrt[3]{1728}=\sqrt[3]{12 \times 12 \times 12}=12

As need to multiply 12 by \sqrt[3]{14903}

\Rightarrow 12 \times \sqrt[3]{14903}

On solving \sqrt[3]{14903}, we get

\sqrt[3]{14903}=24.608

\Rightarrow 12 \times \sqrt[3]{14903}=12 \times 24.608=295.306

Hence cube root of 1728 is 12 and on multiplying it by cube root of 14903 we get 295.306.

1. Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and
Andru [333]

Suzette ran for 1.6 hours and biked for 2.4 hours.

Let x = total hours Suzette ran.

Let y = total hours Suzette biked.

The equation to solve the question will be:

x + y = 4 ...... i

6.5x + 14y = 44.75 ....... ii

From i, y = 4 - x

Put the value of y into equation ii

6.5x + 14y = 44.75

6.5x + 14(4 - x) = 44.75

6.5x + 56 - 14x = 44.75

Collect like terms

6.5x - 14x = 44.75 - 56

-7.5x = -11.25

x = 11.25/7.5

x = 1.6 hours

Since x + y = 4

1.6 + y = 4

y = 4 - 1.6

y = 2.4 hours.

Suzette ran for 1.6 hours and biked for 2.4 hours.
