The answer should be D.

The maximum amount she can add is 7 books and no more, so the first two are wrong. It’s also allowed to be exactly seven, which is why it would be a closed circle.

Hope this helps!

The length of a rectangle is 15ft greater than the width. The area is 100 square ft. Find the length and the Width.

gogolik [260]

Step-by-step explanation:

so let's say that the width is x then the length is x+15

and the area of a square is length times width

x(x+15)=100

x^2+15x-100=0

(x+20)(x-5)=0

x=5 or x=-20 but a side length can't be negative so x would equal 5

Length=x+15 with 5 as x

Length=20

Width=5

Hope that helps :)

Find the product and write in lowest term. Give me an integer or simplified fraction. 7/54×27/35

wariber [46]

The product of given expression is $\frac{1}{15} \text{ or } 0.0667$

Solution:

Given that we have to find the product and write it in lowest term

Given expression is:

$\frac{7}{54} \times \frac{27}{35}$

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

$54 = 27 \times 3\\\\35 = 7 \times 5$

Substituting these in above expression, we get

$\rightarrow \frac{7}{27 \times 3} \times \frac{27}{7 \times 5}$

Cancel the common factors in numerator and denominator

$\rightarrow \frac{1}{15}$

In decimal form, we get

$\rightarrow \frac{1}{15} = 0.0667$

Thus the product of given expression is $\frac{1}{15} \text{ or } 0.0667$
