A square has an area of 64x^2y^4. What is its side lenght and perimeter

Answers

Answer 1

Answer:

For this case we have that by definition, the area of a square is given by: $A = l ^ 2$

Where:

l: It's the side of the square

We have as data that:

$A = 64x ^ 2 * y ^ 4$

So:

$64x ^ 2 * y ^ 4 = l ^ 2$

We cleared l, applying root to both sides:

$l = \pm \sqrt {64x ^ 2 * y ^ 4}$

We choose the positive value of the root:

$l = \sqrt {64x ^ 2 * y ^ 4}\nl = 8xy ^ 2$

So, the side of the square is: $8xy ^ 2$

The perimeter is given by:

$P = 4l\nP = 4 (8xy ^ 2)\nP = 32xy ^ 2$

Answer:

$l = 8xy ^ 2\nP = 32xy ^ 2$

Answer 2

Answer:

Answer:

Side length = 8xy^2

Perimeter = 32xy^2.

Step-by-step explanation:

As it's a square the side length is the square root of the area

= √ (64x^2y^4)

= 8xy^2.

The perimeter is 4 times this.

-2(10r + 4) + 10(7r + 2)

Answers

Answer:

$\large\boxed{-2(10r+4)+10(7r+2)=50r+12}$

Step-by-step explanation:

$-2(10r+4)+10(7r+2)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\n\n=(-2)(10r)+(-2)(4)+(10)(7r)+(10)(2)\n\n=-20r-8+70r+20\qquad\text{combine like terms}\n\n=(-20r+70r)+(-8+20)\n\n=50r+12$

The answer would be 50r+12

-2(10r+4)+10(7r+2)

Remove parentheses

-20r-8+70r+20

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Number of flowers= 48

Number of flowers in each vase = 6

So, number of vase can be made

= 48/6

= 8 vases

Now, if each vase cost $2 then cost 8 vase

= 8 x 2

= $16.

#SPJ2

First, you have to do 48/6. Which should give you 8. Now, since he brought 48 flowers and put 6 in each vase, there'll be 8 cases. So, you take the number of cases and multiply it by $2. Which will give you 16. So therefore, Mr.Garcia made a profit of $16!

You will need to buy________ pounds of pecans.

Give your answer accurate to at least one decimal place.

Answers

Answer:

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.

Step-by-step explanation:

We are given the following information in the question:

Number of pecan pies to be made = 4

Pecan required to make 1 pie = $1(1)/(2) \text{ cups}$

Pecan required to make 4 cups =

$4* 1(1)/(2) = 4* (3)/(2) = 6\text{ cups}$

Now, 1 bag of pecan has a serving size of 1 cup . Hence, we need to buy 6 such bag.

Now, weight of one bag = 99 grams

Weight for 6 cups of pecan = $6* 99 = 594\text{ grams}$

We know that:

1 gram = 0.00220462 Pounds

594 grams of pecans = $594* 0.00220462 =1.30954428 \text{ pounds of Pecan}$

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.

To solve this problem, first determine the information you need to answer. As we need to make 4 pecans of the pies, take the values for the one piece and multiply it with four.

To make 4 pecans pies one will required to by 1.30 pounds of pecan.

Given information:

Number of pecan pies to be made is 4

The pecan needed to make 1 pie is $1.5$ cups.

Now, Pecan required to make 4 cups will be:

$4 * 1.5 = 6$ cups.

As, 1 bag of pecan has a serving size of 1 cup

Hence, we need 6 such bags.

Now, weight of the bag is 99 grams

so,

weight of 6 such bags will be

$=6* 99\n=594 \;\text{gm}$

And we have

$1 \; \text{gm}=0.00220462 \; \text{pound}$

So,

594 grams of pecans = $594* 0.00220462$

$=1.3095 \;\text{pounds}$

Hence, to make 4 pecans pies one will required to by 1.30 pounds of pecan.
