Suzanna walked two over seven of a mile in two over five of an hour. What is her unit rate in miles per hour?
Kruka [31]

Two sevenths over two fifths = five over seven mile per hour

The unit rate is 5 over 7 miles per hour

<em><u>Solution:</u></em>

Given that, Suzanna walked two over seven of a mile in two over five of an hour

We have to find the unit rate in miles per hour

Unit rate means number of miles covered in 1 hour

From given information,

Two over seven of a mile in two over five of an hour

Which means,

\frac{2}{7} \text{ miles } = \frac{2}{5} \text{ hour }

\text{ So she covered } \frac{2}{7} \text{ miles in } \frac{2}{5} \text{ hour }

To find for number of miles covered in 1 hour, divide the \frac{2}{7} \text{ by } \frac{2}{5}

\text{Unit rate in miles per hour } = \frac{\frac{2}{7}}{\frac{2}{5}}\\\\\text{Unit rate in miles per hour } = \frac{2}{7} \times \frac{5}{2} = \frac{5}{7}

Two sevenths over two fifths = five over seven mile per hour

Thus unit rate is 5 over 7 miles per hour

This is a picture of a square pyramid and the net for the square pyramid.
Lelu [443]
We know that
surface area of the square pyramid=area of the base+4*[area of lateral triangle]

area of the base=b²----> area of square
b=6 ft
area of square=6*6---> 36 ft²

area of lateral triangle=b*h/2
b=6 ft
h=9 ft
area of lateral triangle=6*9/2---> 27 ft²

surface area of the square pyramid=36+4*27----> 144 ft²

the answer is
144 ft²
