A Man buys two mobiles for Rs. 2,000 each. He sells one of
them at 10% profit and other at 5% loss, what percent of
profit or loss is there in the total transaction?

Answers

Answer:

2.6%

Step-by-step explanation:

CP of each phone =2000

total cp = 4000

in 1st case

profit = 10 %

so,sp = cp + 10 % of xp

= 2000 + 10/100 ×2000

= 2200

in 2and case

loss =5%

so sp=cp - 5% of cp

=2000 - 5/100 × 2000

=1900

so total sp = 4100

so profit % = sp - cp/cp ×100%

= 2.5

Britney bought 4 apples, 5 bananas, and 8 oranges at the grocery store. Which is the ratio of apples to bananas written as a decimal? A. 2 B. 0.5 C. 0.4 D. 0.8

Answers

Answer:

D. 0.8

Step-by-step explanation:

The ratio in mathematics indicates how many times one number contains another. To find this ratio you must make division of both nubers. For example the ratio of X to Y is X/Y.

As there are 4 apples to 5 bananas, the ratio of apples to bananas is:

4/5 = 0.8

Right answer is:

D. 0.8

Solve x -8y = 15 for y.
y =?
(Use integers or fractions for any numbers in the expression.)

Answers

Answer:

y = -15/8 + x/8

Step-by-step explanation:

x - 8y = 15

Solve for y.

Subtract x from both sides of the equation - -8y = 15-x

Divide -8 from both sides of the equation - y= -15/8 + x/8

(The negative from the x and 8 cancel out and become positive)

Answer:

y=x-15/8

Step-by-step explanation:

Subtract x from both sides

Divide both sides by −8.

Dividing by −8 undoes the multiplication by −8.

Divide 15−x by −8.

Function P is defined as P (x) = x ^2 . Explain why P (2) + P (3) isn't equal to P (5) .

Answers

Answer:

P(x) = x + 2

Piden: A = P(P(P(P(3))))

P(3); x = 3

P(3) = 3 + 2 = 5

A = P(P(P(P(3))))

A = P(P(P(5)))

P(5); x = 5

P(5) = 5 + 2 = 7

A = P(P(P(5)))

A = P(P(7))

P(7); x = 7

P(7) = 7 + 2 = 9

A = P(P(7))

A = P(9)

P(9); x = 9

P(9) = 9 + 2 = 11

→ A = P(P(P(P(3)))) = 11

1.9 X 0.46
Answer anyone?

Answers

0.874 is the answer to 1.9 x 0.46

1.9 × 0.46 is equals to 0.874

What is a decimal ?

A decimal can be represented by a dot which separates the whole part and the fractional part of a given number.

Multiplying decimals can be simplified if we take out the decimals and just multiply them as whole numbers

∴ 1.9 × 0.46 ⇒ 19 × 46

= 874

Now the two numbers had total 3 digits after the decimal places.

So, in our obtained result we will put the decimal 3 digits before starting from the rightmost digit.

∴ 874 ⇒ 0.874

The given series 1, -1,... is arithmetic progression series whose pattern is a, a +d, a + 2d, a + 3d + a + 4d , ....

What is Arithmetic progression?

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

The arithmetic progression is more often used, for instance in the sum of natural numbers.

1, 2, 3, 4, 5, 6, 7, and 8 are natural numbers.

The difference between any two subsequent terms is now the same: d = 2-1 = 3-2.

Given,

1 , -1 , ...

If we subtract the second term from first

-1 - 1 = -2

So, a common difference between the series will be -2

Now,

Third term = a + 2d = 1 + 2 (-2) = -3

Fourth term = a + 3d = 1 + 3 (-2) = -5

Fifth term = a + 4d = 1 + 4 (-2) = -7

Hence the general rule will be a, a +d, a + 2d, a + 3d + a + 4d , ....

how do you sovle this 5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

Answers

Answer: X=-3

Step 1) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-4)+3*x-9*x-(6-(2*x+5)+8*x)=0

Step 2) ((5 • (x - 4) + 3x) - 9x) - (6x + 1) = 0

Step 3) Pull out like factors : -7x - 21 = -7 • (x + 3)

Step 4) -7 • (x + 3) = 0

Step 5) Solve : -7 = 0 This equation has no solution.

A a non-zero constant never equals zero.

Step 6) Solve : x+3 = 0

Subtract 3 from both sides of the equation :

x = -3
