Answer:
Step-by-step explanation:
Finding the percentage of the cost that is the tip means finding the percentage of the reduction or fall in price on the initial price.
The initial price of the shirt is $27
There was a reduction in price from $27 to $20. Reduction in price is determined by subtracting the new price from the original price. Therefore
Reduction in price(tip) = 27 - 20 = 7
To determine the percentage of the cost that is the tip, we will divide the tip by the initial cost and multiply by 100. It becomes
7/127 × 100
= 25.93%
Given Situation: What is the percent increase from the 20 students to the 30 students.
Solution:
=> Let’s find how many percent did it increase.
Let’s have 20 as the first total number of the students in the first counts.
=> Then it became 30 students, let’s find out how many students added.
=> 30 – 20 = 10, there are 10 students added
10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.
Answer:
-2/3
Step-by-step explanation:
slope=change in y/change in x
3-1/4-7 = -2/3
Answer:
Find the value of x, if 8,x, x, 50 are in proportion.
If a,b,c and d are in proportion then we have a/b = c/d
Now we need to find the value of x given if 8, x, x, 50 are in proportion.
So we have 8/x = x/50
Or x x x = 8 x 50
Or x^2 = 400
Or x = ±√400
Or x = ± 20
Therefore the value of x will be + 20 or - 20
