No(0)Let the cost price of the 20 pens be ₹100.

Cost of each pen=₹100/20=₹5

Selling price of each 25 pens sold=₹100/25=₹4.

%LOSS:

If cost of each pen. = 5=100%

..selling price of each pen. = 4= ?%.

Cross multiply:5? =400

?=80%

So,%loss= 100%-80%=20%

Answer:

0.09 and 0.04

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30

The probability that a person at a show is a "superfan" is 20%=0.20

Two people are selected at random.

The probability that both people have both seen the band perform live before  = The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.30 x 0.30

=0.09

Similarly, the probability that both are  "superfans"   = The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.20 x 0.20

=0.04

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

Answer:

Step-by-step explanation:

Where are the answer choices?

Still, it's possible to help you without your having shared those choices.

The "difference quotient" is defined as:

 f(x + h) - f(x)

--------------------

           h

where h represents an incremental (small) change in x.

Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).

Therefore the difference quotient is:

{3 - log (x + h)} - {3 - log x}

-------------------------------------

                    h

This can be simplified.  In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x

and the difference quotient is

-log ( x + h) + log x

---------------------------

              h

This can be rewritten as

log x - log (x + h)                                x                                  x

--------------------------- , or (1/h)*log ------------ , or  (1/h) log { ----------- }

              h                                       (x + h)                            x + h

Answer:

7^3 + 7^3 units^3

OR

(7^3)2 units^3

Step-by-step explanation:

Volume = length x width x height

In cubes, length = width = height

So, volume = 7 x 7 x 7 = 7^3

2 cubes:

7^3 + 7^3 units^3

OR

(7^3)2 units^3

Answer: 45 divided by 3 equals 15

he has 15 dollars

Step-by-step explanation: 45= 3 times 15

Answer: 45=3a   a=15

Step-by-step explanation:

We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

Answer:

x = 10.2

Step-by-step explanation:

10.2 × 10 = 102...

Answer:

x+10=102

Step-by-step explanation:

the word "increased" signifies addition because of the value getting larger. the word "is" indicates an equal sign. therefore, the equation is x+10=102

Answer:

Step-by-step explanation:

Complementary angles are two angles that add up to be 90 degrees.

We can write an equation and solve for x.

(3x - 4) + (5x + 6) = 90

~Combine like terms

8x + 2 = 90

~Subtract 2 to both sides

8x = 88

~Divide 8 to both sides

x = 11

Angle DEF:

3x − 4

3(11) - 4

33 - 4

29°

Angle FEG:

5x + 6

5(11) + 6

55 + 6

61°

Check:

29 + 61 = 90°

Best of Luck!

Answer:

$1.25 per pound

Step-by-step explanation:

Step 2:

$3.75 ÷ 3         Divide

Answer:

$1.25 : 1

Hope This Helps :)

The required rate for granola in dollars per pound is 1.25.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The total money spent on granola is $3.75.

And, the amount of granola is 3 pounds.

The unit rate for the given case can be found using unitary method as,

Money spent for 3 pounds = $3.75

Then, money spent for 1 pound = 3.75/3 = $1.25

Hence, the rate of granola $1.25 per pound.

Answer:

For each question, just subtract the bigger number from the smaller one :D

Answer:

Yes, it matters which way you subtract values because if you subtract a larger number from a smaller number you will get a negative nummber, but when you subtract the smaller number from the bigger number you get a positive number

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]

Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).

[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]

Distribute:

[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]

Simplify:

[tex]2x-4x=x+24[/tex]

Combine like terms:

[tex]-2x=x+24[/tex]

Subtract [tex]x[/tex] from both sides of the equation:

[tex]-3x=24[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:

[tex]x=-\frac{24}{3}[/tex]

Simplify:

Answer:

32

Step-by-step explanation:

Answer:

32 + 4x ≤ 50

Step-by-step explanation:

Cost of tickets = $32

Cost of soda = $4

Total spent = $50

When we say "no more than", we mean less than or equal to (≤)

He buys 1 tickets and x sodas

32 + 4x ≤ 50

4x ≤ 50 - 32

4x ≤ 18

Divide both sides by 4

x ≤ 18 / 4

x ≤ 4.5

Shawn can buy more than 4 sodas
