Answer:
36 gallons
Step-by-step explanation:
y = 4/5x
Let x = 45 minutes
y = 4/5 (45)
y = 36 gallons
At time t = 1 hr... fee is initial ($12)+ ($8) = 20
<span>and so on... the intercept would be initial fee... which is $12 charged at t=0 hr
</span>
8$ per hour is the essentially the slope
<span>12 is the initial charge also known as the y-intercept </span>
<span>y = 8x + 12 </span>
where y is the total charge and x is the number of hours
hope it helps
Answer:
B measures 66°
C measures 66° .Sum of all angels is 180° .
72/3=24
24/12=2(2 meters a person a day)
2*15=30
15 people can build about 30 meters of fence a day.
Answer:
x = 133°
Step-by-step explanation:
Straight-line pair - A pair of angles that lie on a straight line.
<em>*</em><u><em>Property</em><em>*</em></u>
The sum of two angles of a straight-line pair is equal to <u>180°</u>.
The given angles – x and y – form a <u>straight-line pair.</u>
==> x + y = 180
<em>{</em><em>y</em><em> </em><em>=</em><em> </em><em>4</em><em>7</em><em>°</em><em> </em><em>(</em><em>given</em><em> </em><em>in</em><em> </em><em>t</em><em>he</em><em> </em><em>question</em><em>)</em><em>}</em>
<em>Substituting</em><em> </em><em>4</em><em>7</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 47 = 180
<em>Subtracting</em><em> </em><em>4</em><em>7</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> x = 47 - 47 = 180 - 47
==><u> x = 133</u>
