Answer:

D is the right one

Step-by-step explanation:

π radian = 180 degree

-> 135 degree = \frac{135}{180} π radian

-> 135 degree = 0.75 * π  radians = 3π/4 radian

A environmental scientist buys 20 gallons of oil eating bacteria to help remediate an area affected by an oil spill. The volume
ahrayia [7]

Answer:

  • 2.6 ft³

Step-by-step explanation:

Let the required volume be x

<u>Use the ratio of gallon/volume to solve:</u>

  • 1/0.13 = 20/x
  • x = 20*0.13
  • x = 2.6 ft³

With 20 gallons the scientist can cover 2.6 ft³ of water volume

Solve. h - 18 1/2 = -7 3/4
barxatty [35]
Make the denominators the same:

h - 18( \frac{2}{2}) ( \frac{1}{2}) =  \frac{2}{4} = -7 \frac{3}{4}

bring the 18 1/2 to the other side: 

h=11 1/4

Given: Q=7m + 3n, R= 11 - 2m, S= n + 5, and T= -m - 3n + 8 <br><br><br> simplify R - [S + T]
Soloha48 [4]
R = 11-2m
S = n+5
T = -m-3n+8
---------------------------
Add up S and T to get...
S+T = (n+5)+(-m-3n+8)
S+T = n+5-m-3n+8
S+T = -m+(n-3n)+(5+8)
S+T = -m+(1n-3n)+(5+8)
S+T = -m+(-2n)+(13)
S+T = -m-2n+13
---------------------------
Subtract that result from R
R - [S + T]
11-2m - [-m-2n+13]
11-2m +m+2n-13
(-2m+m) + (2n) + (11-13)
(-2m+1m) + (2n) + (11-13)
(-1m) + (2n) + (-2)
-m + 2n - 2
---------------------------
---------------------------
The final answer is -m + 2n - 2
