there is a rectangle abcd.the length of the rectangle is increased by 10%.the width of the rectangle is increased by 5%,what is

lesya [120]

Answer:

Therefore the area of rectangle is increased by 15.5%.

Step-by-step explanation:

Assume the length and width of the rectangle be x and y respectively.

The area of the rectangle is = length×width

=xy.

Now the length of the rectangle is increased by 10%.

Then the length of the rectangle increased = $x\times \frac{10}{100}$ .

New length of the rectangle is $=x+\frac{10x}{100}$

$=\frac{100x+10x}{100}$

$=\frac{110x}{100}$

The width of the rectangle is increased by 5%.

Then the width of the rectangle increased = $y\times \frac{5}{100}$ .

New length of the rectangle is $=y+\frac{5y}{100}$

$=\frac{100y+5y}{100}$

$=\frac{105y}{100}$

New area of the rectangle is = $\frac{110x}{100}\times\frac{105y}{100}$

= 1.155 xy.

The percentage of area increase is

$=\frac{\textrm{New area - Original area}}{\textrm{Original area}}\times 100$

$=\frac{1.155xy-xy}{xy}\times 100$

$=\frac{0.155xy}{xy}\times 100$

=15.5.

Therefore the area of rectangle is increased by 15.5%.

the product of 8 and a number , increased by 52, is equivalent to the product of 12 and the sum of the number and 2 . find the n

Step2247 [10]

8n+52=12(n+2)

distribute

8n+52 = 12n+24

subtract 8n from each side

52=4n +24

subtract 24 from each side

28 = 4n

divide by 4 on each side

7=n

Alex and Ben were given a total of £240 They shared the money in the ratio 5:7

AfilCa [17]

Answer:

Ben received: £140

Step-by-step explanation:

Total amount = £240

Given ratio: 5:7

It means £240 is divided into 12 parts

So 1 part will be equal to: £240/12

1 part = £20

Now given ratio is:

5:7

Multiplying each share with £20

5*(£20) : 7* (£20)

£100: £140

So according to ratio amounts:

Alex received: £100

Ben received: £140

I hope it will help you!
