pls help 25h²- 16t² factorise it​

Answers

Answer 1

Answer:

(5h-4t)(5h+4t)

Step-by-step explanation:

25h² - 16t²

adding  and subtracting 20ht from it        (√25 and √16 = 5x4 = 20):

25h² + 20ht - 20ht -16t²

factor:

(5h-4t)(5h+4t)

Answer 2

Answer:

(5h - 4t)(5h + 4t)

Step-by-step explanation:

25 h² - 16t² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Then

25h² - 16t²

= (5h)² - (4t)²

= (5h - 4t)(5h + 4t) ← in factored form

System of equations that have the same slope have what kind of lines?

Answers

Answer:

parallel lines

Step-by-step explanation:

with an infinite number of solutions

Answer:

I think you are intended to answer parallel lines

Step-by-step explanation:

There are two answers to this.

1) The lines could be parallel if their y intercepts are different.

2) The lines are different forms of the same line.

For example

parallel:

y = 3x + 5y = 3x - 2

Different forms of the same line.

y = 4x + 22y = 8x +4

The second condition is termed consistent. The second condition is of 2 lines with the same slope and the same y intercept.

The slope of the line that passes through the points (6, w) and (10, 4) is 8. What is the value of w?

Answers

Answer:

My student the slope paserea the Pointe 6w and 10,4 is8

w= -28

To find slope, you would use the equation
y-y1/x-x1

So: 4-w/10-4

We know it must equal 8 so let’s set is equal to 8 and solve :D

4-w/10-6=8

4-w/4=8

4-w=32

-w=28

w=-28

Cooper is going to invest $2,100 and leave it in an account for 14 years. Assuming the interest is compounded monthly, what interest rate, to the nearest tenth of a percent, would be required in order for Cooper to end up with $5,300?

Answers

Answer:

6.6

Step-by-step explanation:

I just did this :)

The interest rate annually will be 6.6% for the given compound interest will be 6.6%.

What is compound interest?

Compound interest is applicable when there will be a change in principal amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.

As per the given,

Principle amount P = $2100

Time period T = 14 years

The annual rate of interest is R

Total investment = $5300

Number of times interest applied per time period n = 12

By compound interest formula,

5300 = 2100[1 + R/(100)]^(12 x 14)

(1 + R/1200)¹⁶⁸ = 5.524

1 + R/1200 = 5.51 x 10⁻³

R = 6.6% annually

Hence "The interest rate annually will be 6.6% for the given compound interest will be 6.6%".

So for this problem all we have to do is plug in the given values into the expression so now we have

5(3) - 2(4)  - -2

5x3=15

-2x4=-8

now we have

15-8-(-2)

15-8=7

remember when you subtract a negative number the two negative signs cancel out and turn into a positive so instead of

7--2 it would be 7+2

7+2=9

so the answer is 9

Melissa buys a Television set whose marked prize was rupees 45000 , her then gets a discount of 15% and pants a sales tax of 12% , how much does he pay for the television set ​

Answers

Answer:

43650 rupees

Step-by-step explanation:

Discount = D

Tax : T

D = 15% of 45000

D = (45000 x 15) ÷ 100

D = 675000 ÷ 100

D = 6750 rupees

The price after the discount :

45000 - 6750 = 38250 rupees

T = 12% of 45000

T = (45000 x 12) ÷ 100

T = 540000 ÷ 100

T = 5400 rupees

Melissa will pay :

 (45000 - 6750) + 5400

= 38250 + 5400

= 43650 rupees

If the area of a rectangle is 64cm squared, how many different perimeters are possible when the dimensions are whole numbers

Answers

Answer:

2 different perimeters, 32 cm and 40 cm

Step-by-step explanation:

Given the area of a rectangle is 64 cm squared.

We know, Area of the rectangle is = length x breath

∴  64 = 8 x 8

Hence the sides can be 8 cm by 8 cm.

So the perimeter of the rectangle is = 8 cm + 8 cm + 8 cm +8 cm

                                                            = 32 cm

Also, Area of the rectangle is = length x breath

∴  64 = 16 x 4

So the perimeter of the rectangle is = 16 cm + 4 cm + 16 cm +4 cm

                                                            = 40 cm

An inspector of school have wishes to distribute 84 balls and 180 bats equally among the number of boys . Find the greatest number recieving the gift in this way

Answers

Answer:

12 boys

Step-by-step explanation:

Given that:

Number of balls to be distributed = 84

Number of bats to be distributed = 180

To obtain the greatest number of boys receiving these items ; obtain the Highest common factor of both numbers ;

84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180

The highest common factor here is 12, hence the greatest number of boys receiving the gifts is 12.

Use midpoint formula to find the coordinates of B:

x = (x1 + x2)/2, y = (y1+ y2)/2

Substitute known values and solve for x and y:

-5 = (-8 + x)/2 ⇒ -10 = -8 + x ⇒ x = -10 + 8 ⇒ x = -2 0 = (5 + y)/2 ⇒ 0 = 5 + y ⇒ y = 0 - 5 ⇒ y = -5
