Answer: B
4x^{6} - 2x^{5} + 4x^{3} -x^{2} +4x
Step-by-step explanation:
Answer:
<u><em>You will need to purchase 16 more gallons that cost $2.29 each for your final amount to be $36.64</em></u>
Step-by-step explanation:
You need to find how many miles you can get per gallon to use 160 miles on 5 gallons.
=
. Meaning your unit rate for this would be 32 miles for 1 gallon
You then need to find out how many gallons you will need if you're going to 640 miles and get 32 miles per gallon.
= 20
Meaning you will need 20 gallons.
Now since you already know how many gallon you have which is 4. Then you know how much you need, 20 - 4 = <u>16</u>
Then since they will be $2.29 each, multiply 2.29 by 16 to get <u>$36.64</u>
Meaning you will need to <u><em>16 gallons costing 2.29 each</em></u> and you will spend <u><em>$36.64 dollars on the trip</em></u>
Given:
The given degree measurement is -60 degrees.
To find:
The radian measure of the given degree measure.
Solution:
We know that,
![\text{Radian measure}=\text{Degree measure}\times \dfrac{\pi}{180^\circ}](https://tex.z-dn.net/?f=%5Ctext%7BRadian%20measure%7D%3D%5Ctext%7BDegree%20measure%7D%5Ctimes%20%5Cdfrac%7B%5Cpi%7D%7B180%5E%5Ccirc%7D)
The radian measure of -60 degrees.
![\text{Radian measure}=-60^\circ \times \dfrac{\pi}{180^\circ}](https://tex.z-dn.net/?f=%5Ctext%7BRadian%20measure%7D%3D-60%5E%5Ccirc%20%5Ctimes%20%5Cdfrac%7B%5Cpi%7D%7B180%5E%5Ccirc%7D)
![\text{Radian measure}=-\dfrac{\pi}{3}](https://tex.z-dn.net/?f=%5Ctext%7BRadian%20measure%7D%3D-%5Cdfrac%7B%5Cpi%7D%7B3%7D)
Therefore, the radian measure of the given degree measure is
.
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
Mean is 11.3 and the range is 4. Dont need to add 5 for all. Just do mean for the given options and add 5 at the end. Same with the range 9-5=4. Doesn’t change when you add 5 for all
