35x+55(110-x)=4850
Solve for x
X=60 for 35
110-60=50 for 55
Let T = the distance, in miles, a tire lasts
T ~ N(70000,4400<span>²</span>)
P(T

75000)
= P(Z

)
= P(Z

)
≈ P(Z

1.14)
= 1 - P(Z < 1.14)
≈ 1 - 0.8729
= 0.1271
Answer:
45,45,90
Step-by-step explanation:
3x + 3x + 6x= 180
12x=180
x= 180/12= 15
3x=3×15=45
3x=3×15=45
6x=6×15=90
Based on the dimensions of the parking area, we know that the cost of resurfacing will be <u>$3,135.</u>
First find the area of the parking area:
<em>Area of trapezoid = (Base ₁ + Base₂) / 2 x Height </em>
= (90 + 100) / 2 x 30
= 2,850 feet²
The cost of resurfacing is:
<em>= Area x cost per square foot </em>
= 2,850 x 1.10
= $3,135
It will cost $3,135 to resurface the place.
