Answer:
25%
Step-by-step explanation:
48+48(the 2 sweaters)= 96
48+48(0.5)=72
72/96=0.75
you pay 75%, so that means its 25% off.
We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.

Answer:
B & D
Step-by-step explanation:
We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
There are two ways to look at it:
For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22=78. If 20% off is the sale, then we pay 80% or 0.80. Multiply that by x an unknown price and we have 0.8x.
We can find the percent off by multiplying the price by the percent conversion. So 20% is 0.20. Then subtract it from the original price to find the leftover that we pay. This is x-0.2x.
Answer:
The expression for the total amount of Jamal earned is $ (14 y + 55)
Step-by-step explanation:
Given as :
The bonus amount earn by Jamal = $ 55
According to question
On Thursday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 9 hours of work , Jamal will earn 9 × y = 9 y dollars
On Friday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 5 hours of work , Jamal will earn 5 × y = 5 y dollars
So, The total earning on both days of his work = 9 y + 5 y = 14 y dollars
Since Jamal also earn bonus of $ 55
So, Total earning of Jamal including bonus = 14 y + $ 55
Hence The expression for the total amount of Jamal earned is $ (14 y + 55) Answer
