The sum of the squares of two positive numbers is 73 and the difference of the squares of the numbers is 55. Find the numbers. If there
use the "or" button

Answers

Answer 1
x^2+y^2=73
x^2-y^2=55

x^2=73-y^2

73-y^2-y^2=55
-2y^2= -18 multiply both sides by -1
2y^2=18 divide both sides by 2
y^2=9
y= √9
y=3

x^2=73-9
x^2=64
x= √64
x=8

Check:
64+9=73
64-9=55

Good luck

Answer 2

The two numbers are 3 and 8.

What are squares of a number?

Square numbers are numbers that can be multiplied by themselves.

Given that, The sum of the squares of two positive numbers is 73 and the difference of the squares of the numbers is 55.

Let the numbers be x and y, then,

x²+y² = 73

x²-y² = 55

On solving, we get,

x² = 9

x = 3

Putting x = 3 in first equation, we get

3²+y² = 73

y² = 64

y = 8

Hence, the required numbers are 3 and 8.

To purchase $13,900 worth of lab equipment for her business, Amy made a down payment of $1900 and took out a business
loan for the rest. After 3 years of paying monthly payments of $365.07, she finally paid off the loan.

Answers

Answer:

The total cost was $ 15,042.52, and the interest percentage applied on the loan was 8.22%.

Step-by-step explanation:

Given that to purchase $ 13,900 worth of lab equipment for her business, Amy made a down payment of $ 1900 and took out a business loan for the rest, and after 3 years of paying monthly payments of $ 365.07, she finally paid off the loan to determine the total cost and interest applied on the loan, the following calculation must be made:

(365.07 x 12 x 3) + 1900 = Total cost

4,380.84 x 3 + 1900 = Total cost

13,142.52 + 1900 = Total cost

15,042.52 = Total cost

13900 = 100

15042.52 = X

15042.52 x 100/13900 = X

1,504,252 / 13,900 = X

108.22 = X

Therefore, the total cost was $ 15,042.52, and the interest percentage applied on the loan was 8.22%.

I have 48 candys for 50cents each, how much total will I have after I sell all 48 candies?

Answers

Answer:

the answer is 2400 cents

Step-by-step explanation:

if you have 48 candies and each cost 50 cents so u meltiply 48 with 50. so if u mutiply them u get 2400cents, but if u want them in dollar then 1 dollar is 100 cent so if 1 dollar = 100 cent

                   ?        = 2400 cent

you criss -cross them so when u do 2400 multiplyed by 1 is 2400 and 100 multiplyed by ? is 100?  

so your going to get this

2400 = 100?

so u divide both sides by 100 because u want "?" alone. so when u do 100 will vanish because you divided both sides with 100

so it will look something like this

2400/100 = ?

when u divide 2400 with 100 u get 24.

what does that mean? it mean 2400 cents are 24 dollars

do you get it?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a recipe calls for 2 1/2 cups of flour to make 18 muffins. If someone needs to make 2 1/2 times the recipe.

The amount of flour required will be calculated as:-

2 (1/2) flour ⇒ 18 muffins

2.5 flour ⇒ 18 muffins

2.5 x 2.5 flour ⇒ 2.5 x 18 muffins

6.25 flours ⇒ 45 muffins

Therefore, to make 45 muffins the amount of flour required will be 6.25.

the perimeter of a rectangle is 36cm.If it is length is 10 cm find its breadth​

Answers

Answer:

The perimeter of a rectangle is 36 cm, its breadth is 8 cm

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 36 cm

length (L) = 10 cm

Now,

Perimeter (P) = 2 × (length + breadth)

P = 2 × (l + b)

36 = 2 × (10 + b)

36 = 20 + 2b

2b = 36 - 20

2b = 16

b = 16 ÷ 2

b = 8 cm

Thus, The perimeter of a rectangle is 36 cm, its breadth is 8 cm

-TheUnknownScientist

Question:-

The perimeter of a rectangle is 36 cm. If its length is 10 cm, find its breadth.

Answer:-

Given:-

[tex] \bullet [/tex] Perimeter (P) of a rectangle is 36 cm.

[tex] \bullet [/tex] Length (L) of a rectangle is 10 cm.

To Find:-

Breadth (B) of a rectangle.

Solution:-

We know,

P = 2(L + B)

So,

36 = 2(10 + B)

36 = 20 + 2B

36 - 20 = 2B

16 = 2B

B = 16/2 = 8 cm.

Breadth (B) of a rectangle is 8 cm. [Answer]
