Answer:
$1000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 1000 × 0.03 × 5 = 150
I = $ 150.00
The simple interest accumulated
on a principal of $ 1,000.00
at a rate of 3% per year
for 5 years is $ 150.00.

26 laps
Step-by-step explanation:
Olivia : Alexis = 3 : 4
3x + 4x = 63
7x = 63
x = 9
Alexis = 4 x 9 = 36
Answer:
21.5%
Step-by-step explanation:
The area of the 4 circles together = 4×π×12^2
The area of the square = 48^2
then the probability that the point is in one of the circles =
(4×π×12^2)÷48^2
=0.785398163397
Therefore, the probability that the point is not in a circle =
1 - 0.785398163397 = 0.214601836603
converted into percentage : 21.4601836603
rounded = 21.5%
Answer:
$1679.175 or $1679.18
Step-by-step explanation:
split the carpet into rectangles to make it easier to look at
one rectangle is 2 yards in height and 9 yards in width (5 yards plus 4 yards)
area of a rectangle = (w)(h), so 9 x 2 = 18 yards in area.
second triangle is 4 yards in width, and 3 yards in height.
area of a rectangle = (w)(h), so 4 x 3 = 12 yards in area.
Total area = 30 yards
30(21.95)(2.55) = $1679.175 or $1679.18
Answer:
Each bike with both types of tire.
Half of the tires of each type will be in the front wheel and the other half in the rear wheel.
Step-by-step explanation:
To compare the wear of each type of tire in a matched-pair test, the individuals have to test each of the tires in the same conditions.
This will allow to compare the tires wear in equal conditions. If the tires are assigned randomly to the volunteers, there will be difference in the wear due to difference habits of the bikers.
The only way to implement a matched-pair test with bikes is to use one type of tire in the front wheel and the other type in the rear wheel. Half of the tires of each type will be in the front and half in the rear.
In this way, the distance traveled with each type of tire will be the same.
