Answer:

$\frac{19 \pi}{15}$

Step-by-step explanation:

To convert a given angle from degrees to radians, we multiply by

$\frac{ \pi}{180}$

The given degree measure is 228°

Its radian equivalence is

$\frac{ \pi}{180} \times 228 = \frac{19 \pi}{15}$

Therefore the exact value of 228° is

$\frac{19 \pi}{15} \: radians$

Step 1: Define

Find points from graph.

Point A(0, 8)

Point B(4, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{5-8}{4-0}$
[Fraction] Subtract: $\displaystyle m=\frac{-3}{4}$

Ellen drove 357.9 miles. Her car gets about 21 miles per gallon. Which is the best estimate of how many gallons of gas Ellen use

olga55 [171]

The best thing to do is to divide the amount she has driven (357.9) by the miles (21)
As you're looking for an estimate, you have to round them.
357.9 rounds to 360
21 rounds to 20
Therefore, you've got to divide them
360/20= 18
Therefore, Ellen has driven approximately 18 miles
Hope this helps :)

Amiraneli [1.4K]

Answer:

$4357.25$

Step-by-step explanation:

Given the following question:

$4357.25$
$4357.250$
$0$
$=4357.25$

The following number is already rounded two decimal places which means the answer is "4357.25."

In case you meant one decimal place....

$4357.25$
$5=5$
$=4357.3$

Hope this helps.
