Answer:

Her average speed was 60 miles per hour.

Step-by-step explanation:

150 divided by 5 is 30.

30 x 2 = 60

Because 2 1/2 contains 5 half hour.

When you get that single half hour you times it by 2 since 1 hour is made up of 2 half hour. Which makes 60 miles per hour.

There are 158 birds on the endangered species list in some year. this is 16 more than twice the number of reptiles on the list.

S_A_V [24]

Let the number of reptiles on endangered list be 'x'

2x + 16=158

2x=158-16

2x=142

x=71

So there are 71 reptiles on the endangered list

55° is equal to 0.9599 radians.

Step-by-step explanation:

Step 1:

If an angle is represented in degrees, it will be of the form x°.

If an angle is represented in radians, it will be of the form $\frac{\pi}{x}$ radians.

To convert degrees to radians, we multiply the degree measure by $\frac{\pi}{180}$ .

For the conversion of degrees to radians,

the degrees in radians = (given value in degrees)( $\frac{\pi}{180}$ ).

Step 2:

To convert 50°,

$55\left(\frac{\pi}{180}\right)=\frac{55\pi}{180}.$

$0.3055 (\pi) =0.9599$ radians.

So 55° is equal to 0.9599 radians.
