Answer:
Percentage Rate=6%
Step-by-step explanation:
Total borrowed=$2,100
Time=3 years
Rate=?
Total amount owed after 3 years= total borrowed + simple interest
$2,478=$2,100 + x
X=$2,478 - $2,100
=$378
The simple interest=$378
Simple interest=P×R×T
Where,
P= principal=$2,100
R=Rate=?
T=Time=3 years
Simple interest=$378
Simple interest=P×R×T/100
$378=$2,100×R×3/100
$378=$6,300R/100
$378=$63R
R=$378/$63
R=6
Therefore,
Rate=6%
The perimeter of the front face of the prism = 88 feet.
The front face of a prism is a two-dimensional figure.
The side lengths are 2x feet, 4x+8, 2x feet, and 4x+8 feet.
Since both the opposite sides of the face are equal, it is a rectangle.
The perimeter is the sum of all the sides of the rectangle.
2x+(4x+8)+2x+(4x+8) = 88 feet
12x +16 =88
12x = 88-16
12x = 72
x = 72/12
x=6 feet
Hello from MrBillDoesMath!
Answer:
7.7 % (approximately)
Discussion:
65 * x% = 65 * (x/100) = 5 => (multiply both sides by 100)
65 *( x/100)* 100 = 5 * 100 =>
65x = 500 =>
x = 500/65 = 7.7 (approx)
