Firstly, to calculate a price you need to change the percentage into a decimal. You do this by dividing it by 100.
45 / 100 = 0.45,
The discount price will be 55% of the original price,
55 / 100 = 0.55,
19 * 0.55 = 10.45,
So the discound price will be $10.45
Hope this helps!
Answer:
p=7/2
Step-by-step explanation:
Rember that a p series can be represented by
Here, notice that
This is true for all parts of the series because
So p=7/2
Four times the sum of a number and 15 is at least 120
Let ‘x’ represent the number.
"The sum of a number and 15"
This can be written mathematically as x + 15
Given that 4 times this sum is at least 120,
This means that 4 times the sum is greater than or equal to 120
This can be written mathematically as 4(x + 15) >= 120
Solving for x
4(x + 15) >= 120
4x + 60 >= 120
4x >= 120 – 60
4x >= 60
x >= 60/4
x >= 15
x is greater than or equal to 15

Answer:
Point B will be -7 + 4 i
Step-by-step explanation:
We have given point 
And mid point = -2 + i
We have to find point B
We know that mid point is given by
As the mid point is in between the point A and B
So point B will be -7 + 4i
