The owner of a bike shop sells unicycles and bicycles and keeps inventory by counting seats and wheels. one day, she counts 21 seats and 30 wheels. which equation in slope-intercept form shows that x bicycles and y unicycles together have a total of 30 wheels?

a. y = -2x - 30
b. y = -2x + 30
c. y = 2x + 30
d. y = 2x - 30

a

step-by-step explanation:

i dont know the answer but here's a picture of a dog

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
