Answer:
y = 60x + 22
262 miles
Step-by-step explanation:
Given that the car enters the turnpike at 22 miles, his initial starting point, or initial value (b) is 22. You also know the rate at which the car travels is 60 miles per hour, which is the slope (m). Using the slope-intercept formula of a linear function: y = mx + b, you can plug in your initial value and rate:
y = 60x + 22, where y = the total miles and x = the number of hours traveled
After 4 hours:
y = 60(4) + 22 = 240 + 22 = 262 miles
Answer:
The answer is 153.8
Step-by-step explanation:
To find the perimeter you sum all the sides. 5.9+12.3+12.3+10.9+12.3+23.2+18.2+10.9+12.3+35.5= 153.8
Answer:
64√3 ft²
Step-by-step explanation:
The short leg of the triangle has length (8 ft)(cos 60°), or (8 ft)(1/2), or 4 ft.
The long leg (represented by the dashed line) is (8 ft)(sin 60°), or
(8 ft)(√3/2), or 4√3. This is also the width of the horizontal trapezoid.
The area of this horizontal trapezoid is:
(sum of horizontal sides)
A = ------------------------------------- * (width)
2
Here, the area is:
(18 ft + (18 ft - 4 ft)
= ------------------------------------- * (4√3)
2
32 ft
= ----------- * 4√3 = 64√3 ft²

Answer: B = 73
Step-by-step explanation:
Since A = 17 degrees and there's already a right angle (90 degrees)
They add up to 107 degrees meaning the last angle is 73 because
the sum of interior angles add up to 180.
I'm sorry I couldn't find the other ones ( I don't have time )
but I'll give you a hint. You'll need to use Sine, Cosine, or Tangent
