A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%

The sum of four consecutive integers is 386. What is the fourth integer?
Licemer1 [7]

The 4 consecutive integers are 95, 96, 97 and 98.

The fourth integer is 98.

<u>Step-by-step explanation:</u>

Let us consider the 4 consecutive integers to be 'x' , 'x+1' , 'x + 2' , 'x + 3'  

The sum of the 4 consecutive integers= 386

x + (x+1) + (x+2) + (x+3) = 386

4x + 6 = 386

4x = 380

x = 380/4

x = 95

x+1 = 96

x+2 = 97

x+3= 98

The 4 consecutive integers are 95, 96, 97 and 98.

The fourth integer is 98.

Hii please answer number 8 I’ll give brainliest thanks!
Alex787 [66]
The answer is 3/5 simplified.

Reasoning:
There are 6 solid white and solid black marbles combined.

There are total of 10 marbles.

Of the 10 marbles, you are 6/10 times likely to pull one of the solid black or white marbles.

Simplify 6/10 by dividing it by a number they both share (2) to get the answer of 3/5.

Solve for x. Enter you answer in the box.
Nikitich [7]

Answer:

x = 6

Step-by-step explanation:

AD is a midline segment and divides EB and EC  in the same proportion, that is

\frac{EA}{AB} = \frac{ED}{DC}

Substituting in values gives

\frac{16}{x+2} = \frac{12}{24} = \frac{1}{2} ( cross- multiply )

5x + 2 = 32 ( subtract 2 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6
