Alex and Jill share £100 in the ratio of 1 : 7 work out how much money Alex gets?​

Answers

Answer 1

Answer:

$87.50

Step-by-step explanation:

If they split the money 1:7 this means they divided it into 8 portions. (Because 7+1=8). So do $100/8=12.5.

(You never specified who got 1 portion and who got 7, so I will assume Alex got the 7)

Let's say Jill got the 1 portion, she gets $12.50.

Let's say Alex got the 7 portion, he got $12.50 x 7 = $87.50

Answer 2

The amount Alex got is £12.5.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

Alex and Jill share £100 in a ratio of 1:7.

Total ratio = 8x

So,

Alex = 1x

Amount = 1x/8x x 100 = £12.5

Jill = 7x

Amount = 7x/8x x 100 = £87.5

Thus,

Alex got £12.5.

Answer:

36 degrees

Step-by-step explanation:

Angles on a line equal 180

180-117=63

a=63

Angles in a triangle equal 180

180-(63+81)=36

b=36 degrees

Answer:

a=117(being straight line angle)

a=180-117

a=63ans

a+b+81=180(being the sum of the angle of triangle)

b+63+81=180

b+144=180

b=180-144

Answer:

(6x²+13x+6) ÷ (2x+3) sq in

Step-by-step explanation:

Volume = base × height

6x³+13x²+6x = (2x²+3x)h

Divide both sides by (2x²+3x)

(6x³+13x²+6x) ÷ (2x²+3x) = (2x²+3x)h ÷(2x²+3x)

By Factorization

x(6x²+13x+6) ÷ x(2x+3) = h

h= (6x²+13x+6) ÷ (2x+3)

Therefore the height of the prism is (6x²+13x+6) ÷ (2x+3) sq in

The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's policies the marked price of the retailer should be the same as the dealer's marked price. What SP should the retailer fix for the jacket? What would its final price be if 10% VAT is imposed? What would be the actual gain of retailer?
Ans
2280,2502,240​

Answers

Answer:

2400

2640

360

Step-by-step explanation:

the retailer has to sell it for the same price as the dealer.

so, both mark it for 2400 sale price.

if a customer buys it at the retailer, the retailer makes the 15% discount he got from the dealer as profit.

2400 = 100%

1% = 2400/100 = 24

15% = 24×15 = 360

the retailer makes this profit no matter what other fees or taxes are added.

the final price is then including 10% VAT

2400 = 100%

10% = 24×10 = 240

final price = SP + VAT = 2400 + 240 = 2640

Given:

[tex]m=0.56x-0.25[/tex]

To find:

The sum of m and n.

Solution:

We have,

[tex]m=0.56x-0.25[/tex]

[tex]n=0.20x-0.03[/tex]

The sum of m and n is:

[tex]m+n=(0.56x-0.25)+(0.20x-0.03)[/tex]

Combining the like terms, we get

[tex]m+n=(0.56x+0.20x)+(-0.25-0.03)[/tex]

[tex]m+n=(0.76x)+(-0.28)[/tex]

[tex]m+n=0.76x-0.28[/tex]

Therefore, the sum of m and n is [tex]m+n=0.76x-0.28[/tex].

2s/n-a=L

Step-by-step explanation:

So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L.

in the circl below, AD is diameter and AB is tangent at A. Suppose mADC=228*, find the measures of mCAB and mCAD. Type your numerical answers without units in each blank.

Answers

Given:

AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.

To find:

The [tex]m\angle CAB[/tex] and [tex]m\angle CAD[/tex].

Solution:

AD is diameter of the circle. So, the measure of arc AD is 180 degrees.

[tex]m(arcADC)=m(arcAD)+m(arcDC)[/tex]

[tex]228^\circ=180^\circ+m(arcDC)[/tex]

[tex]228^\circ-180^\circ+=m(arcDC)[/tex]

[tex]48^\circ+=m(arcDC)[/tex]

The measure inscribed angle is half of the corresponding subtended arc.

[tex]m\angle CAD=\dfrac{1}{2}\times m(arcDC)[/tex]

[tex]m\angle CAD=\dfrac{1}{2}\times 48^\circ[/tex]

[tex]m\angle CAD=24^\circ[/tex]

AB is the tangent. So, [tex]m\angle BAD=90^\circ[/tex] because radius is perpendicular on the tangent and the point of tangency.

[tex]m\angle BAD=m\angle CAB+m\angle CAD[/tex]

[tex]90^\circ=m\angle CAB+24^\circ[/tex]

[tex]90^\circ -24^\circ=m\angle CAB[/tex]

[tex]66^\circ=m\angle CAB[/tex]

Therefore, [tex]m\angle CAB=66^\circ[/tex] and [tex]m\angle CAD=24^\circ[/tex].

Find the rate, or percent, for each of the following items. Round your answers to the nearest 0.1%.

Base 72; percentage 12

Percentage 28; base 224

Base 20; percentage 40

Base 44; percentage 99

Percentage 126; base 8400

Answers

Answer:

The percentages are as follows: 1) 16.6%, 2) 12.5%, 3) 200%, 4) 225%, and 5) 1.5%.

Step-by-step explanation:

To find the rate, or percent, for each of the following items, the following calculations must be performed:

1) Base 72; percentage 12 = 12/72 = 0.1666 x 100 = 16.6

2) Percentage 28; base 224 = 28/224 = 0.125 x 100 = 12.5

3) Base 20; percentage 40 = 40/20 = 2 x 100 = 200

4) Base 44; percentage 99 = 99/44 = 2.25 x 100 = 225

5) Percentage 126; base 8400 = 126/8400 = 0.015 x 100 = 1.5

Therefore, the percentages are as follows: 1) 16.6%, 2) 12.5%, 3) 200%, 4) 225%, and 5) 1.5%.
