Solve If QR = 6x + 1, PR = 14x - 13, and PQ = 5x - 2, find PR
Answer:
P____Q____R
PR= PQ+ QR
(14x-13) = (5x-2)+(6x+1)
14x-13= 11x – 1
14x – 11x = 13–1
3x = 12
x= 12/ 3
x= 4
PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5
If you want (PQ , QR ) this is the solution
PQ =5x-2=5(4)-2=20-2=18
QR =6x+1=6(4)+1=24+1=25

The volume of a sphere is 36-pie-ft-three squared
what is the radius of the sphere use the formula v= 4/3 -pie- r-3 squared
Answer:
3 ft
Step-by-step explanation:
V = 4/3 π r³
36 π = 4/3 π r³
=> eliminate π
36 = 4/3 r³
r³ = 36×¾
r³ = 27
r = ³√27
r = 3
so, the radius of the sphere = 3 ft
Volume=36π
4/3πr³=36π4/3r³=3r³=36(3/4)r³=27r=3ftA class has 28 students. The ratio of girls to boys is 4:3. How many girls are in the class

Share £360 into the ratio 3:2:1
Answer:
£180, £120 and £60.
Step-by-step explanation:
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3*60 = 180
2*60 = 120
1 * 60 = 60.
The distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.
What is a ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
The number of parts = 3 + 2 + 1 = 6.
360 / 6 = 60, so the shares are:
3 x 60 = 180
2 x 60 = 120
1 x 60 = 60.
Hence the distribution of £360 in the ratio of 3:2:1 will be £180, £120 and £60.

Use the formula m =m equals StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction to calculate the slope of the line.
The slope of the line is
.
Answer: 2 is correct
Step-by-step explanation:
The slope of the line passing through the points (-6, -8) and (2, 8) is 2.
Used the formula for the slope of the line passing through the points

Use absolute value notation to represent the distance between x and 8 is no more than 4
| x - 8 | ≤ 8 will be the absolute value notation to represent the distance between x and 8 is no more than 4.
What is absolute value?Absolute values are the value of any digit without considering the sign.
So all negative values will be considered positive for absolute value.
For example, the absolute value of -2 will be 2 and the absolute value of -7 will be 7.
Given that,
Distance between x and 8
Now,
If x < 8 then x - 8 will negative and if x > 8 then it will positive.
So we need to use the mode function.
So,
| x - 8 | is distance between x and 8
Now it is no more than 4 so it is less than and equal to 8.
So,
| x - 8 | ≤ 8
Hence "| x - 8 | ≤ 8 will be the absolute value notation to represent the distance between x and 8 is no more than 4".

A company offering short term loans agrees to lend Nick $1,200. The amount (plus interest) is repayable in one year, and the interest rate is 12% per month. What is the total amount that must be repaid?
Answer:
$2,928 in 1 year
Step-by-step explanation:
Amount lent = $1,200
Monthly interest rate = 12%
Period = 12 months
Interest accrued = Amount lent * Monthly interest rate * Period
Interest accrued = $1,200 * 12% * 12
Interest accrued = $1,200 * 1.44
Interest accrued = $1,728
Amount repaid = Amount lent + Interest accrued
Amount repaid = $1,200 + $1,728
Amount repaid = $2,928
