Find the circumference to see how much of the wheel is touhing the ground

c=2pir
c=2pi1.9
c=2.8pi

2.8pi=distance per 1 rotation
number of rotations per second times 2.8pi=12feet per second
dvide both sides by 2.8pi
number of rorations per second=12/2.8pi
number of roations per second=6/1.4pi
number of roations per second=3/0.7pi
number of roations per second=30/7pi
aprox
number of roations per second=1.364 rotations per second

Ms. Trowbridge will receive a 40% discount off her first cell phone bill. Her monthly cell phone plan charges a flat monthly fee
Sholpan [36]

Answer: $51.00

Step-by-step explanation:

Since $0.20 is charged per minutes , that is , the amount charged for 300 minutes will be :

300 x 0.20 = $60

Her monthly cell phone plan charges a flat monthly fee of $25.00 , that is the total amount charged will be

$60 + $25

= $85

There is a 40% discount , then we have

40% of $85

= $34

So, the amount of her first cell phone bill = $85 - $34

= $51.00

The length if Marshall's rectangular poster is 2 times its width.If the perimeter is 24 inches, what is the area of the poster.
4vir4ik [10]
Length=2x
width=x
Perimeter of a rectangle=2(lenght)+2(width)

The first is to find out the measures of this rectangle, that is to say, you have to find the length and width of these rectangle.

We can suggest this equation:
24=2(2x)+2(x)
4x+2x=24
6x=24
x=24/6
x=4

2x=2(4)=8

The lenght will be 8 in, and the length will be 4 in.

The second; you have to calculate the area of this rectangle.
area of a rectangle= lenght x width

area=(8 in)(4 in)=32 in²

answer: the area of Marshall´s rectangular poster would be 32 in²
