Angle 1 and angle 2 form a linear pair.if m angle =5x+9 and m angle 2=3x+11,find the measures of both angels.
lbvjy [14]

Answer: ∠1 = 109°    ∠2 = 71°

<u>Step-by-step explanation:</u>

If the two angles form a linear pair, then their sum is 180°

  ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

              8x + 20  = 180

              8x          = 160

                x          = 20

∠1 = 5x + 9

    = 5(20) + 9

    = 100   + 9

    = 109

∠2 = 3x + 11

     = 3(20) + 11

     =    60  + 11

     =         71

  <u> CHECK:</u>

∠1   + ∠2 = 180°

109° + 71° = 180°

     180°   = 180°  \checkmark

The rate at which sand is poured into a bag is modeled by the function r given by r(t)=15t−2t2, where r(t) is measured in millil
balu736 [363]

Answer:

35 mililiters

Step-by-step explanation:

Given

r(t) = 15t - 2t^2

Required

Accumulated amount from t = 0 to 2

This implies that, we substitute the values of t from 0 to 2 in the function

r(0) = 15*0 - 2*0^2= 0

r(1) = 15*1 - 2*1^2= 13

r(2) = 15*2 - 2*2^2= 22

The accumulated sand (r) is:

t = r(0) + r(1) + r(2)

r = 0 + 13 + 22

r = 35

A service station checks Mr. Smith's radiator and finds it contains only 40% antifreeze. If the radiator holds 20 quarts and is
storchak [24]

Answer:

8 quarts

Step-by-step explanation:

<u>Step One: Figure out how much 40% is by making an equation:</u>

<em>Since we are looking for a percentage, we use cross multiplication to find X.</em>

\frac{x}{20} = \frac{40}{100}

<u>Step Two: multiply 20 by 40 to start cross multiplying:</u>

<em>20 times 40 is 800, so replace the 40 by 800 in the equation.</em>

\frac{x}{20} = \frac{800}{100}

<u>Step Three: divide 800 by 100, and we will have X:</u>

<em>800/100=8</em>

<em><u>X=8 aka 8 quarts</u></em>

I hope this helps!

pls give thx and brainliest :D
