Answer:

$= {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

Step-by-step explanation:

$= \frac{ {x}^{ - 9} {y}^{ - 5} {z}^{ - 7} }{ {x}^{2} {y}^{6} {z}^{3} } \\ = {x}^{ - 9 - 2} {y}^{ - 5 - 6} {z}^{ - 7 - 3} \\ = {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

Mia can run at a rate of 360 feet per minute. Approximately how many minutes would she take to run a 500-yard stretch of road an

tankabanditka [31]

Step-by-step explanation:

since we know, she can run 360 ft per minute, and we want to know how many minutes she would need to run 500 yards we need to find out how often 360 ft fit into 500 yards.

so,

500 yards / 360 ft

how can we make this division ?

help is given to us by taking us that 1 yard = 3 ft.

aha !

so, 500 yards = 500×3 ft = 1500 ft

therefore, our task now looks like

1500 ft / 360 ft

and this we understand and can do, right ?

1500 / 360 = 150/36 = 75/18 = 4 3/18 = 4 1/6 minutes

the closest answer option is therefore 4.2, meaning she would take about 4.2 minutes to run 500 yards.

The height of the flag pole is 51 ft.

Solution:

Paul creates the smaller triangle and flag pole creates the larger triangle.

Base of smaller triangle = 10 ft

Height of smaller triangle = 6 ft

Base of the larger triangle = 85 ft

Let the height of the flagpole be h.

$$\Rightarrow \frac{6}{10} =\frac{h}{85}$

Multiply by 85 on both sides.

$$\Rightarrow 85 \times \frac{6}{10} =\frac{h}{85} \times85$

$$\Rightarrow \frac{510}{10} =h$

⇒ 51 = h

The height of the flag pole is 51 ft.
