If there are 1000 grams in a kilogram and 454 grams in a pound, how many pounds are there per kilogram?

Answers

Answer 1

Answer:2.2 pounds per kilogram

Step-by-step explanation:

454gram = 1 pound

since; 1000g = 1kg

454g = x

x= 454/1000

x=0.454kg

there is 0.454kg in 1 pound

but the question says how many pound is in 1kg

0.454kg = 1 pound

1 kg = x

cross multiply

0.454x = 1

Divide bothside by 0.454

x = 1/0.454

x = 2.2 pound

Therefore; there are 2.2pounds in 1 kilogram.

Answer 2

There are 2.20 pounds are there per kilogram

Given that,

1 kg = 1000 gm

1 pound = 454 gm

Since we know that,

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Since,

1 pound = 454 gm

Therefore,

⇒ 454 gm = 1 pound

⇒ 1 gm = 1/454 pound

And since,

1 kg = 1000 gm

= 1000x(1/454) pound

= 2.20 pounds

Hence,

1 kg = 2.20 pounds

Veronica is shopping for school clothes. She wants to buy pants and shirts. The cost of her clothes can be found using the expression 30x + 25y where x is the number of pants and y is the number of shirts. She will also have to pay 8% tax. If Veronica buys two pants and eight shirts, what expression could be used to determine the total cost of the bill including 8% tax?

Answers

Hey there.

I'll list the variables so we're clear.

x = 2, y = 8

So far the expression looks like this: (i'll come back to the 8%)

30(2) + 25(8)

60 + 200 = 260

Cool, now we have the price before tax. We can add the sales tax by multiplying $260 by 8% as a decimal.

260 · 0.08 = 20.80

260 + 20.80 + 280.80

The total cost of Veronica's bill is $280.80

Cheers!

Final answer:

To find the total cost of Veronica's school clothes including 8% tax, first calculate the cost before tax with her specific quantities of pants and shirts, and then add the tax. The final expression shows a total cost of $280.8.

Explanation:

Veronica is shopping for school clothes, and the cost of her clothes can be found using the expression 30x + 25y, where x is the number of pants and y is the number of shirts. She will also have to pay 8% tax. If Veronica buys two pants and eight shirts, the expression to determine the total cost of the bill including 8% tax would be:

First, substitute x = 2 (pants) and y = 8 (shirts) into the expression to find the total before tax: 30(2) + 25(8).Calculate the cost before tax: 60 + 200 = 260.Calculate the total with 8% tax: 260 + (0.08 × 260).The final expression to determine the total bill is: 260 + 20.8 = 280.8.

Determine if (-2, 10) is a solution of 5x+3y=20

Answers

plug in the -2 into "x", and plug in 10 into "y", because (x,y)

5(-2) + 3(10) = 20

-10 + 30 = 20

20 = 20

True

(-2,10) is a solution

hope this helps

To determine if (-2,10), all we have to do is plug in the appropriate values for x and y into the equation given to us, 5x + 3y = 20. When we use x = -2 and y = 10, we get 5(-2) + 3(10) = 20. When we simplify down, we get -10 + 30 = 20 => 20 = 20. Therefore, the coordinate point (-2, 10) is a solution of 5x + 3y = 20. Hope this helped and have a great day!

(7 * 800 = 5,600) ; +
___________________________________________
(7 * 1,000 = 7,000) ;
___________________________________________
Now, add the the values together to solve the problem:
___________________________________________
→ 7 * 1,829 = 63 + 140 + 5,600 + 7,000 ;

The rectangular backboard of a basketball court needs to be assembled. Its area is given as 18,900 cm2 and the width as 1.8 m.

What is the backboard’s length in metres?

Answers

Answer:
1.05

Explanation:
The formula for area is:
A = l • w
So to find the length, you would rearrange to make:
l = A ÷ w
1.8 m = 180 cm
So:
l = 18,900 ÷ 180
l = 105 cm
105 cm = 1.05 m

Answer:

1.05 m

Step-by-step explanation:

The area of the rectangular backboard is A = 18900 cm²

And the width is w = 1.8 m = 1.8 ×100 = 180 cm

The area of the rectangle is given by

[tex]A=l\cdot w[/tex]

Substituting the known values

[tex]18900=l\cdot 180\\\\l=\frac{18900}{180}\\\\l=105\text{ cm}[/tex]

Thus, the length of the backboard's is 105 cm = 1.05 m

What is the meaning of factors?

The factor means a number that can be multiplied or divided to produce a given number.

Consider the given polynomial 12x^3-9x^2-4x+3.

We will factorize using a grouping of terms,

Taking 3x^2 common from the first two terms and -1 common from the last two terms, we have,

3x^2(4x-3)-1(4x-3)

Now, again taking (4x-3) common, we have,

(4x-3)(3x^2-1)

Thus, The factors of the given polynomial are (4x-3)(3x^2-1).

https://brainly.com/question/25829061#SPJ3

Final answer:

The factored form of 12x3 - 9x2 - 4x + 3 is (3x2 - 1)(4x - 3).

Explanation:

The expression 12x3 - 9x2 - 4x + 3 can be factored as follows:

First, identify any common factors among the terms. In this case, the greatest common factor (GCF) is 1.

Next, group the terms:

12x3 - 9x2 - 4x + 3 = (12x3 - 9x2) + (-4x + 3)

Factor out the GCF from each group:

12x3 - 9x2 = 3x2(4x - 3)

-4x + 3 = -1(4x - 3)

Combine the factored terms:

(3x2 - 1)(4x - 3)

Therefore, the factored form of 12x3 - 9x2 - 4x + 3 is (3x2 - 1)(4x - 3).
