Mr. Tan's rectangular swimming pool has an area of (81x2 - 144y2) square feet. What are the dimensions of his pool?

Answers

Answer 1

Answer:

The pool dimensions are thus  (9x - 12y)(9x + 12y)

Step-by-step explanation:

(81x^2 - 144y^2) is the difference of two squares.  Note that you must indicate exponentiation with " ^ ."

Factoring the difference of two squares:  a^2 - b^2 = (a - b)(a + b)

Thus,  (81x^2 - 144y^2)  =

The pool dimensions are thus  (9x - 12y)(9x + 12y)

Answer 2

Area of rectangle is Length times of Breadth. The pool dimensions are  (9x - 12y) and (9x + 12y) when area of rectangular swimming pool is  (81x2 - 144y2)

area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2), we need to find the area of rectangle.

What is area of rectangle?

Area of rectangle= Length*Breadth

The given area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2),

(81x^2 - 144y^2)=Length * Breadth

We know that (a+b)(a-b)=a^2-b^2

So,

The factors of (9x^2-12y^2) is (9x+12y) and (9x-12y)

(9x^2-12y^2)=(9x+12y)(9x-12y)

=Length * Breadth

where length and breadth are two dimensions of rectangle

Therefore (9x+12y) and (9x-12y) are two dimensions of rectangle.

Luis purchased a laptop computer that was marked down by
[tex] \frac{2}{5} [/tex]
of the original price. What fractional part of the original price did Luis pay?​

Answers

Answer:

Luis paid 3/5 of the original price

Step-by-step explanation:

Luis purchased a laptop with a fractional discount of 2/5 of the original price.

When dealing with fractional parts of a whole, the sum of all parts must equal 1. With this in mind, we can say:

Paid price + Discount price = Original price

Or, equivalently:

paid fraction + discount fraction = 1

From the above relation, it follows that:

paid fraction = 1 - discount fraction

[tex]\displaystyle \text{paid fraction }=1-\frac{2}{5}[/tex]

[tex]\displaystyle \text{paid fraction }=\frac{5-2}{5}[/tex]

[tex]\displaystyle \text{paid fraction }=\frac{3}{5}[/tex]

Luis paid 3/5 of the original price

question: Zayn has 5 more than three times the number of stickers that cleo has. Cleo has 25 fewer stickers than zayn. WRITE THE SYSTEMS OF EQUATION TO REPRESENT THIS SITUATION. explain what the solution means

Answers

Answer:

Solutions:

Z = 35

C = 10

Systems of Equations:

Z = 3C + 5

C = Z - 25

Step-by-step explanation:

Z will be for Zayn and C will be for Cleo.

Z = 3C + 5

C = Z - 25

These are the systems of equations. To solve, plug one of the equations into their respected variable.

Z = 3(Z - 25) + 5

Z = 3Z - 20

20 = 2Z

Z = 10

C = 3C + 5 - 25

-2C = -20

C = 10

This proves that these equations are correct. To find the final solution, plug 10 into Z to find Zayn's amount , then plug the amount that was for Zayn into C to find Cleo's amount.

Z = 3(10) + 5

Z = 35

C = 35 - 25

C = 10

What is rectangle?

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape

Given:

Area of rectangular section of her wall =76.5 ft.²

Height of the design = 8.5 feet.

We know that

Area of rectangle=length*breadth

Area = l*h

76.5   =8.5*l

l=76.5/8.5

l= 9 feet.

Therefore, the minimum length of the design Jaunice will paint on the wall is 9 feet.

One factory needs 6 buttons to make 1 witch costume. Fill in the rate table to determine how many witch costumes the factory can make with 18, 42, 66, or 84 buttons

Answers

Answer:

The factory can make 3 witch costume from 18 buttons

The factory can make 7 witch costume from 42 buttons

The factory can make 11 witch costume from 66 buttons

The factory can make 14 witch costume from 84 buttons

Step-by-step explanation:

Let us use the ratio method to complete the table

∵ A factory needs 6 buttons to make 1 witch costume

∵ There are 18 buttons

→ Find how many witch costume can make from them

→ Buttons → costume

→  6           →  1

→  18          →  x

→ By using cross multiplication

∵ x × 6 = 18 × 1

∴ 6x = 18

→ Divide both sides by 6

∴ x = 3

The factory can make 3 witch costume from 18 buttons

Use the same way to find the rest

∵ There are 42 buttons

→ Buttons → costume

→  6           →  1

→  42         →  x

→ By using cross multiplication

∵ x × 6 = 42 × 1

∴ 6x = 42

→ Divide both sides by 6

∴ x = 7

The factory can make 7 witch costume from 42 buttons

∵ There are 66 buttons

→ Buttons → costume

→  6           →  1

→  66         →  x

→ By using cross multiplication

∵ x × 6 = 66 × 1

∴ 6x = 66

→ Divide both sides by 6

∴ x = 11

The factory can make 11 witch costume from 66 buttons

∵ There are 84 buttons

→ Buttons → costume

→  6           →  1

→  84         →  x

→ By using cross multiplication

∵ x × 6 = 84 × 1

∴ 6x = 84

→ Divide both sides by 6

∴ x = 14

The factory can make 14 witch costume from 84 buttons

Sara has 2 paintings in her portfolio and paints 3 more each week. Kevin
has 12 paintings in his portfolio and paints 2 more each week. After how
many weeks will Sara and Kevin have the same number of paintings? *
12 weeks
O 10 weeks
O 16 weeks
O 14 weeks

Answers

Answer:

If Sara has 2 painting already and paints 3 more each week, and Kevin has 12 paintings already and paints 2 more each week, we go down the list of answers and multiply them by the number of paintings painted each week. So first is 12x2=24 24+12=36    then 12x3=36 36+2=38   now we do 10x2=20 20+12=32   10x3=30 30+2=32 so your answer would be 10 weeks

12 1/3 square feet in 1/5 of an hour. How many square feet can she paint in one hour

Answers

Answer:

30 5/6 square feet

Step-by-step explanation:

Answer:

30 5/6 square feet

Step-by-step explanation:

First you need to know how much she can paint in 1/5 hour. So you're going to be dividing mixed numbers. To do that you need to make 12 1/3 a fraction:

12*3=36

36+1=37

12 1/3= 37/3

Divide by 2. With fractions you flip the second and multiply

37/3 ÷ 2/1 = 37/3 *1/2

Multiply top by top bottom by bottom

37*1=37

3*2=6

37/6 is what she can paint in 1/5 hour

Now you need to multiply that by 5 (5/5= 1 which means a full hour)

So we use 5/1 to multiply by 5 in fraction form.

37/6 * 5/1

37*5=185

6*1=6

Now simplify (turn it back into a mixed number)

185/6= 185÷6

12=12+1/2

v+−4(Distribute)

12=(1/2v)+(12+−4)(Combine Like Terms)

12=1/2v+8

Step 2: Flip the equation.

1/2v+8=12

Step 3: Subtract 8 from both sides.

1/2v+8−8=12−8

Step 4: Multiply both sides by 2.

2*(1/2v)=(2)*(4)

v=8

12 = 12 + (v - 8)/2
Subtract 12 from both sides
0 = (v - 8)/2
Multiple both sides by 2
0 = v - 8
Add 8 to both sides
8 = v

= 8 + 3

= 11

Which of the following is the ratio of nickels to the number of all the coins?

Nickels : Total coins = 3 : 11
