Answer:
y = -240
Step-by-step explanation:
If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion
60/10(-3) = 60/-30 = -2 = k
Now, y/(xz) = -2
y/8(15) = -2
y/120 = -2
y = -240
The length of segment of EF would be 16
Answer:
If Ahmad travel 280 miles the cost of both plans will be the same
Step-by-step explanation:
Let's call x the number of miles traveled by Ahmad.
If we say that C1 is the cost of the first plan and C2 is the cost of the second plan then:
C1 = initial fee + additional cost per mile
C2 = initial fee + additional cost per mile
We want to know for what value of x, cost 1 will be equal to cost 2. Then we equate the equations and solve for x.
5. 180-139=x
6. x=41
The unknown angle is 41°

Determine the area of the shaded part
From the attachment;
<em>Assume that the shaded portion is closed to the right;</em>
<em>Calculate the Area:</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em>
<em>Next;</em>
<em>Calculate the Area of the imaginary triangle (on the right)</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em>
<em>Lastly, calculate the Area of the Shaded Part</em>
<em></em><em></em>
<em></em><em></em>
<em></em><em></em>
<em></em>
<em>Hence,</em>
<em>The area of the shaded part is 72in²</em>
