One of Julian's friends also has a rectangular aquarium. The dimensions of his friend's tank are each exactly 1 1/4 times the di

Answer:

468.75 square inches

Step-by-step explanation:

Let the length of Julian's tank be x

Let the width of Julian's tank be y

So, Area of Julian's tank= $Length \times Width =xy$

Since we are given that Julian's tank is approximately 300 square inches

So, $xy=300$ --1

Now we are given that The dimensions of his friend's tank are each exactly $1\frac{1}{4} =\frac{5}{4}$ times the dimensions of Julian's tank.

So,length of his friend's tank = $\frac{5}{4}x$

So,width of his friend's tank = $\frac{5}{4}y$

So, Area of his friend's tank= $\frac{5}{4}x \times \frac{5}{4}y$

= $\frac{25}{16}xy$

= $\frac{25}{16}(300)$ (Using 1)

= $468.75$

Hence the approximate area of the rectangular base of his friend's tank is 468.75 square inches.

So, Option D is correct.

a particular truck in a transportation fleet was driven 194,070 miles last year versus 329,919 miles this year . by what percent

Ann [662]

We take as the 100% the 194070 miles from last year. Then, we apply a rule of three:

$\begin{gathered} 194070\rightarrow100\text{ \%} \\ 329919\rightarrow x\text{ \%} \\ \Rightarrow x=\frac{329919\cdot100}{194070}=\frac{32991900}{194070}=170 \\ x=170\text{ \%} \end{gathered}$

Since 329,919 is the 170% of last year's miles, then the increase was of 70%
