If the area of a square is 64 square centimeters, whats the length of one side?

A. 8cm
B. 32cm
C. 16cm
D. 4cm

Answers

Answer 1
It's A. 8x8 is 64. Therefore, 8cm is correct.
Answer 2
It would be A because a square has four equal sides. To determine if this is right, you would find the square root of 64 which is 8. To check, find the answer to 8 to the power of two or 8 times 8 which is 64.

Find the product of two numbers whose sum is 11 and difference is 3.

Answers

The two numbers are 7 and 4

Let the first number = x

let the second number = y

The sum of the numbers is 11, in algebra form x + y  = 11

The difference of the two numbers is 3, in algebra form, x - y = 3

To obtain the two unknown numbers, we solve the two equations;

from the first equation, x = 11 - y

substitute the value of x into the last equation;

(11 - y) - y = 3

11 - y - y = 3

11 - 2y = 3

2y = 11 - 3

2y = 8

y = 4

The value of x = 11 - 4 = 7

Thus, the two numbers are 7 and 4

Final answer:

To find the product of two numbers with a sum of 11 and a difference of 3, solve the system of equations to find the numbers (7 and 4) and multiply them to get the product, which is 28.

Explanation:

To find the product of two numbers whose sum is 11 and whose difference is 3, we can let the two numbers be x and y, with x being the larger number. Therefore, we have two equations from the given information: x + y = 11 and x - y = 3.

Adding these two equations, we get:

2x = 14x = 7

Using x = 7 in the first equation, we have:

7 + y = 11y = 4

Now that we have both numbers, we can find their product:

Product = x * yProduct = 7 * 4Product = 28

The product of the two numbers is 28.

Answer:

the first box is "two or more 1s"

the second box is "0.13"

Step-by-step explanation: Im a K12 Student

The probability that 2 or more out of 6 packs will have an all-star card is given by the equation P = 0.1333

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that 2 or more out of 6 packs will have an all-star card be P

The probability of finding an all-star card in a game pack is 12.5 %

The student has pointed that 1 represent a pack with an all-star card and 2 through 8 represent a pack without an all-star card

The test results are given in set A = { 561673, 366468, 314255, 361362, 838443, 126285, 257231, 768551, 652585, 468113, 123711, 322764, 487626, 783134, 384664 }

The number of trials that represent that 2 or more out of 6 packs have an all-star are = { 468113 , 123711 }

Therefore , the probability is given as

Probability that 2 or more out of 6 packs will have an all-star card P = 2/15

On simplifying the equation , we get

Probability that 2 or more out of 6 packs will have an all-star card P = 0.133

Hence , the probability is 13.33 %

Sum of there squares will be as follows:

x² + (x + 2)² = 100

Therefore,

x² + x² + 4x + 4 = 100

2x² + 4x + 4 - 100 = 0

2x² + 4x - 96 = 0

x + 2x - 48 = 0

which equation is true?
f(-10)=1
f(2)=-10
f(0)=6
f(1)=-10

Answers

Answer: f(0) = 6.

Explanation:

Ther ordered pairs are: (x,y) or (x, f(x) )

So, (1,0) means that f(1) = 0 which denies the fourth choice.

(-10,2) means that f(-10) = 2 which denies the first choice

(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.

{(1,0), (-10,2), (0,6), (3,17), (-2,-1)} .

We are to select the TRUE equation.

We know that

Answers

A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter. 
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=[tex]123 \frac{pounds}{mile} [/tex]

Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be: [tex] \frac{1mile}{5280ft} [/tex]
- We also know that there are 16 ounces in 1 pound, so our second multiplier will be: [tex] \frac{16ounces}{1pound} [/tex]
- We know that there are 12 inches in 1 foot, so our third multiplier will be: [tex] \frac{1ft}{12in} [/tex]
- We know that there are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: [tex] \frac{1in}{2.54cm} [/tex]

Now we can put all our multipliers together:
[tex]123 \frac{pounds}{mile} * \frac{1mile}{5280ft}*\frac{16ounces}{1pound}* \frac{1ft}{12in}*\frac{1in}{2.54cm}=0.01 \frac{ounces}{cm} [/tex]

We can conclude that the answer is 0.01

to the nearest whole number, how many times larger is the volume of Earth compared to the volume of our moon? use a radius of 1079 miles for the moon and 3,959 miles for the Earth.

Answers

Well, that would be 3,959 divided by 1079, which is 4 (when rounded up to nearest whole number. Original answer 3.6691)

The volume of Earth is about 49 times larger than the volume of the Moon, based on their provided radii.

To the nearest whole number, the volume of Earth is approximately 49 times larger than the volume of the Moon.

Given that the volumes of spheres are proportional to the cubes of their diameters, and using the radii provided (1079 miles for the Moon and 3959 miles for Earth), we can calculate the volume ratio:

Volume of Earth: [tex](3959)^3[/tex]

Volume of Moon: [tex](1079)^3[/tex]

Volume of Earth compared to the Moon,  = [tex](3959^3) / (1079^3)[/tex] ≈ 49.

A can build the room by himself in 10 days, and B can build the room by himself in 15 days.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's call the faster constructor "A" and the slower constructor "B".

We know that B takes 5 more days than A to complete the job.

Let's call the number of days it takes A to build the room "x".

Then the number of days it takes B to build the room is "x+5".

Now,

We also know that if they work together, they can finish the room in 6 days.

Let's call the fraction of the job that A can do in one day "a"

(which means that B can do "a - 1/6" of the job in one day).

We can use the following equation to solve for "a":

1 = (a + a - 1/6) x 6

Simplifying this equation, we get:

1 = (2a - 1/6) x 6

1 = 12a - 1

12a = 2

a = 1/6

So A can do 1/6 of the job in one day.

We can use this information to solve for "x" and "x+5":

1/x + (1/(x+5)) = 1/6

Multiplying both sides by the least common multiple of the denominators (6x (x+5) ), we get:

6 (x+5) + 6x = x (x+5)

Expanding and simplifying, we get:

x² - 7x - 30 = 0

Solving for x using the quadratic formula, we get:

x = 10 or x = -3

Since x has to be a positive number (because it represents the number of days it takes A to build the room), we can ignore the negative solution.

Now,

It takes A 10 days to build the room, and it takes B 15 days to build the room (since B takes 5 more days than A).

Therefore,

A can build the room by himself in 10 days, and B can build the room by himself in 15 days.

harry buys a sofa set that costs$2,000.he pays for it with 12 month installments. how much will he pay each month? if he has to pay5%in interest how much will he pay in all for the sofa set?

Answers

Harry's monthly payment for the sofa set is approximately $175, which includes principal and simple interest. The estimated total payment amount after 12 months is $2100.

Harry buys a sofa set that costs $2000 and chooses to pay for it in 12 monthly installments. First, to find out the monthly payment without interest, we divide the total cost by the number of installments. So, $2000 divided by 12 months equals to $166.67.

However, there is an interest of 5% on the outstanding amount. To calculate the total interest on an installment plan, we typically would need to calculate the interest on the reducing balance each month; however, for simplicity, let's assume it's 5% of 2000 for the year, which is $100 (5/100 * $2000). Divided by 12 months, that's about $8.33 in interest per month, giving a total monthly payment of $175 ($166.67 + $8.33).

This simplistic approach gives us a rough estimate, and the actual amount could be slightly different due to the reducing balance method used by most financing options. Assuming the simple interest calculation, Harry will pay $175 per month, and in all, he will pay an estimated total of $2100 ($175 * 12) for the sofa set.
