over the weekend, Brady and Jake drove to Key West go scuba diving. Now they're preparing to go home.Brady needs gas for his jee
velikii [3]
His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.

He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal

He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal

With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles

In the Changing Dimensions of 3D Figures
den301095 [7]

Answer:factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is S.A.=2(lw+wb+lb)

Where l=length

w=width

b=breadth

So new length,breadth and width is

l'=3l

w'=3w

b'=3b

S.A.=2(3\times 3lw+3\times 3wb+3\times 3lb)

S.A.=2\times 3^2(lw+wb+lb)

S.A.=3^2\times 2(lw+wb+lb)

So new surface area would change by a factor of 9

Levi wants to order the fractions 1/3, 2/5, and 11/30 in descending order? How can you help him by using a common denominator? E
Georgia [21]

Answer:

The correct order of fractions in descending order will be:

\frac{2}{5}, \frac{11}{30}, \frac{1}{3}

Step-by-step explanation:

Given fraction:

\frac{1}{3}, \frac{2}{5}, \frac{11}{30}

To arrange them in descending order.

Solution:

In order to arrange the fractions in descending order, we will have to find the least common denominators.

To find the least common denominator, we will find the least common multiple of the denominators 3,5, and 30.

Since 30 is a common multiple of all 3 numbers, so it will be the least common denominator.

So, we multiply the numerators and denominators with same numbers in order to make the denominators = 30.

So, we have:

\frac{1}{3}, \frac{2}{5}, \frac{11}{30}

⇒ \frac{1\times 10}{3\times 10}, \frac{2\times 6}{5\times 6}, \frac{11\times 1}{30\times 1}

⇒ \frac{10}{30}, \frac{12}{30}, \frac{11}{30}

Now, we compare the numerators and arrange them accordingly.

\frac{12}{30} > \frac{11}{30} > \frac{10}{30}

So, the correct order of fractions in descending order will be:

\frac{2}{5}, \frac{11}{30}, \frac{1}{3}
