Answer:

She runs about 4.2 miles.

Step-by-step explanation:

6/50 = x/35

6*35 = 50*x

210 = 50x

50x = 210

x = 210/50

x = 4.2

She runs about 4.2 miles.

A prism with a triangular base has a volume of 432 cubic feet. The height of the prism is 8

Rashid [163]

Answer:

9 feet

Step-by-step explanation:

Given:

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of triangular prism = $Area of triangle \times height$

$432 = Area of triangle \times8$

Dividing both side by 8

$54 = Area of triangle$

$54 =$ $\frac{1}{2} \times base \times height$

$54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height$

Multiplying both side by 2

$108 = 12 \times height$

Dividing both side by 12

$9 = height$

Thus, height of the triangular base of the prism is 9

Alan has read 80 percent of a book . He has 16 more pages to finish. How many pages are in the book

Jet001 [13]

Answer:

Step-by-step explanation:

To have 16 more pages means he has 20% more of the book to cover if he has already covered 80%

Let the number of pages in the book be X

20% of X = 16

20/ 100. * X = 16

1/ 5 * X = 16 >>> X = 16 * 5 = 80 pages.
