Answer:
Rotations of tire to travel 500 feet: 95.54
Step-by-step explanation:
Circumference = 20 x 3.14 = 62.8 in
500 feet = 500 x 12 inches = 6,000 in
Rotations = 6000 / 62.8 = 95.54 rotations of tire
Answer:
7 feet and 24 feet
Step-by-step explanation:
In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.
Let x feet and y feet be the lengths of triangle's legs.
By the Pythagorean theorem,
The area of the right triangle is half the product of its legs, thus
Solve the system of two equations:
From the second equation:
Substitute it into the first equation:
The length of the leg cannot be negative, so
The answer is 20.5 feet, because when you draw out the triangle and label the angles and given sides and then use the law of sines, you end up with it.
Answer:
Step-by-step explanation:
-5(y-15=3x) = -5y+75=-15x
add 15x to both sides and subtract 75 to both side
-5y+15x=-75
5y-2x=-3
13x=-78
and then both side divide by 13
x=-6
y-15=3(-6)
y-15=-18
Y= (-18) - 15 = -3
y=-3
and the answer will be (-6,-3)
