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.

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

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
(x₁ , y₁) and (x₂, y₂) would be,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Given that,
A coordinate plane with a straight line passing through the points (-6, -8) and (2, 8).
By using the above formula, the slope of the line is,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
[tex]m = \dfrac{(8 - (-8))}{(2 - (- 6))}[/tex]
[tex]m = \dfrac{(8 + 8)}{(2 + 6)}[/tex]
[tex]m = \dfrac{(16)}{(8)}[/tex]
[tex]m = 2[/tex]

Answer:
BRIANLIEST PLZ
N = 18.75
M = 22.5
Step-by-step explanation:
Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.
T = t1 + t2 = 2.5 + 3 = 5.5
r1 =2.5/5.5
r2 = 3/5.5
Nick = r1 * 41.25 = 18.75
Monica = r2 * 41.25 = 22.5
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".

Why can not use this formula to and the measure of an exterior angle in an irregular polygon? Exterior angle - 360º n
I'm assuming you mean the formula [tex]E = \frac{360}{n}[/tex] where E is the exterior angle measure and n is the number of sides.
This formula only works for regular polygons. Regular polygons have two important properties:
All sides are the same length (eg: all sides are 10 inches long)All angles are the same measure (eg: all angles are 60 degrees)The side length number and angle value do not have to line up. We could have an equilateral triangle where each side is 10 inches long and the three angles are 60 degrees each. Any equilateral triangle is always a regular polygon.
For irregular polygons, we have polygons where one of those two items above (or both) are not the case. This means each exterior angle will not be the same. So we'd have to find another way of finding the exterior angle value.

Step-by-step explanation:
3y+4(y−6)=8y−3(y−10)
3y+4(y−6)=8y−3(y−10) - Simplify
3y+(4)(y)+(4)(−6)=8y+(−3)(y)+(−3)(−10)(Distribute) - Simplify
3y+4y+−24=8y+−3y+30 - Simplify
(3y+4y)+(−24)=(8y+−3y)+(30)(Combine Like Terms)
7y+−24=5y+30
7y−24=5y+30
7y−24−5y=5y+30−5y - Subtract 5y from both sides
2y−24=30
2y−24+24=30+24 - Add 24 to both sides
2y=54
2y/2 = 54/2 - Divide both sides by 2
y=27
