Answer:

[tex]4d^{2}[/tex]

Step-by-step explanation:

Divide the numbers like usual:

12/3 = 4

Note that when you divide powers with common base, you are actually subtracting the power:

[tex]\frac{d^{4} }{d^{2} } = d^{4 - 2} = d^{2}[/tex]

Combine the two for your answer:

[tex]4d^{2}[/tex] is your answer.

Answer:

While there is a strong relationship between the two, it would certainly be ridiculous to talk about a tree with a circumference of –3 feet, or a height of 3000 feet. When we identify limitations on the inputs and outputs of a function, we are determining the domain and range of the function.

3/5 / 5/2 = 3/5 * 2/5 = 6/25

Answer:

Selling price= $580

Step-by-step explanation:

eGiving the following information:

Buying price= $400

Mark-up percentage= 45% = 0.45

The manager applies a mark-up equivalent to 45% of the buying price. First, we need to determine how much is 45% of the cost.

Mark-up= buying price* Mark-up percentage

Mark-up= 400*0.45

Mark-up= $180

Now, the selling price:

Selling price= 400 + 180

Selling price= $580

Answer:

The price per volleyball is $3.

Step-by-step explanation:

Divide $18 by 6 for the cost of each volleyball in which your final answer should be $3 per volleyball.

Answer: $15

The original price of the mirror is unknown, so let's call it x.

The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.

We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.

0.2x = 3

Divide both sides by 0.2.

x = 3/0.2

x = 15

The regular price is $15.

Answer:

1,400 students

Step-by-step explanation:

Calculation for how many actually enroll

First step is to calculate the numbers of students that was accepted

Numbers of students accepted=10,000 students*40%

Numbers of students accepted=4,000 students

Now let calculate the numbers of students that was enrolled

Students enrolled=4,000 students*35%

Students enrolled=1,400 students

Therefore the numbers of students that actually enrolled is 1,400 students

f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.

So in this problem, we're putting a 2 into our function which

means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.

So f(2) = 7 or the value of the function at 2 equals 7.

[tex]f(x) = 3x + 4[/tex]

[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]

Therefore the value of f(2) is 10.

f(a) means the value of f(x) is ... at x = a. Same goes to the f(2) = 10. It means the value of f(x) = 10 at x = 2.

[tex]f(2) = 10[/tex]

Answer:

38.22

Step-by-step explanation:

Remark

You take the discount first. Most places apply a sales tax only when money changes hands (or it should be that way).

Discount

45.50 * 20/100 = 9.10

45.50 - 9.10 = 36.4

Sales Tax

46.4 * 5/100 = 1.82

Total Cost

Total Cost after the discount = 36.4 + 1.82 = 38.22

Answer:

34.44 miles

Step-by-step explanation:

Distance covered bty the two trains :

Distance = speed * time

Time = 30 minutes = 0.5hr

Distance of train 1 = 64 * 0.5 = 32 miles

Distance of train 2 = 52 * 0.5 = 26 miles

Included Angle = 72°

Using cosine rule :

a² = b² + c² - 2bcCosA

Let Distance between the trains after 30 minutes = a

a^2 = 32^2 + 26^2 - 2(32)(26) * Cos(72)

a^2 = 1700 - 514.20427

a^2 = 1185.7957

a = sqrt(1185.7957)

a = 34.435

a = 34.44 miles

* Please let me know if this helped you or tell me if one of my answers are wrong .

Answer:

It is wrong

Step-by-step explanation:

y < 18

This is read as y is less than 18. If the students forgot to flip the symbol and mistakenly believe that y > 18.

y > 18

This is read as y is greater than 18.

There is a difference between the numbers greater or less than 18 .

y must have numbers less than 18 and 21 is greater than 18.

Therefore it is wrong.

But to make it true we can multiply minus with the inequality y > 18

-y > -18

This reverses the inequality sign and it becomes

y< 18

The solution which is required.

I honestly dont know. Maybe you could try to multiply the numbers on the chart? I hope this helped:)

Answer:

60x8 480 -5 475 divided by 2 is 237.5

Step-by-step explanation:

Answer: 0.234375

Step-by-step explanation:

Conversion a mixed number 2 2/

3

to a improper fraction: 2 2/3 = 2 2/

3

= 2 · 3 + 2/

3

= 6 + 2/

3

= 8/

3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/

3

= 6/

3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Divide: 5/

8

: 8/

3

= 5/

8

· 3/

8

= 5 · 3/

8 · 8

= 15/

64

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/

3

is 3/

8

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - five eighths divided by eight thirds = fifteen sixty-fourths.

Answer:

[tex]\frac{1}{81}[/tex]

Step-by-step explanation:

Key skills: Exponents + Fractions

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as [tex]\frac{1}{3^{4}}[/tex]

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!

Answer:

Cost price of the cycle = Rs. 1200

Selling price of the cycles = Rs. 1500

SP > CP ⇒ there is a gain.

⇒ Gain = SP - CP = 1500 - 1200 = Rs. 300

∴ Gain Percentage =

CP

Gain

(100)%

=

1200

300

(100)%=25%

∴ The shopkeeper makes a profit of 25%
