1# What is the side length of a square with an area of 1/16 square units?

2# What is the volume of a cube with edge lengths of 2/3 units?

3# What is the edge length of a cube with a volume of 27/64 cubic units?

Answers

Answer 1

Answer:

#1 1/4


#2. 8/27


#3 3/4

Step-by-step explanation:

let the side of the square be y

Area of a square = y x y = y^2

y^2 = 1/16

y = sqrt (1/16)

y = 1/4


volume of a cube = edge length x edge length x edge length

Volume of a cube = 2/3 * 2/3 * 2/3

Volume of a cube = 8/27


volume of a cube = (edge length)^3

Edge length = cube root (volume of a cube)

Edge length = cube root (27/64)

Edge length = 3/4

It would be -2 , hope this is correct
i think it’s 6 because the y intercept is -1 so you go up till the point because it’s where the line is even if that makes sense.

–8z + – 7z + 6+ –3+ – 6z

Answers

Answer:

-21z + 3

Step-by-step explanation:

That's the simplified version

-21z + 3 is your finals answer because if you take all of the like terms and add them together which is -8z+-7z+-6z=-21z and then you combine your other like terms which is 6+-3= 3 and since you can’t combine 21z and 3 that means -21z+3 is your final answer

Answer:

N = 4

Step-by-step explanation:

I dont know how to show this work.

You basically simplify both sides to find N

And after that you isolate the variable...

Answer:

n = 4

Step-by-step explanation:

We need to make the fraction equal 1, so the equation reads 3 = 2 + 1. To make it 1, n has to be 4 because 4 divided by 4 is 1. We can fact check, too. Just do 3 = 2 + 4/4. 4/4 equals 1. Rewrite it as 3 = 2 + 1, which is obviously correct.

Write 2^60 as an exponent with a base of 8

Answers

Answer: 2^60 = 8^20

Step-by-step explanation: 8=2^3

(2^3)^20 Multiply the exponents

2⁶⁰ written as an exponent with a base of 8 is 8²⁰

From the question,

The given expression is 2^60

In order to write this as an exponent with a base of 8,

First, let us write the given exponent properly.

The given exponent can be properly written as 2⁶⁰

Now, to write this as an exponent with a base of 8, we will apply one of the laws of indices

From one of the laws of indices, we have that

xᵃᵇ = (xᵃ)ᵇ

Then,

2⁶⁰ can be expressed as 2³⁽²⁰⁾

That is,

2⁶⁰ = (2³)²⁰

But, 2³ = 8

∴ 2⁶⁰ = (2³)²⁰ = 8²⁰

2⁶⁰ = 8²⁰

Hence,  2⁶⁰ written as an exponent with a base of 8 is 8²⁰

C because i somehow have the question also...

Answer:

230 2/3 ft

Step-by-step explanation:

Perimeter means add all four sides together

60 5/6 + 54 1/3 + 56 1/6 + 59 1/3

First convert these numbers into improper fractions (it makes adding them together easier)

To convert mixed numbers into improper fractions we multiply the whole number by the denominator and add the numerator (whole number × denominator + numerator)

365/6 + 163/3 + 337/6 + 178/3

To add fractions together they must have a common denominator

A common denominator of 3 and 6 is 6 because 3 × 2 = 6 and 6 × 1 = 6. If we multiply the denominator, then we must also multiply the numerator by the same number

(365/6 × 1/1) + (163/3 × 2/2) + (337/6 × 1/1)+ (178/3 × 2/2)

365/6 + 326/6 + 337/6 + 356/6

Add the numerators together

365 + 326 + 337 + 356 = 1,384

Put the new numerator over the same denominator (6)

1384/6

Both the numerator and denominators are even numbers which means they can be simplified by 2

Divide both the numerator and denominator values by 2

1384 ÷ 2 = 692

6 ÷ 2 = 3

692/3

3 is a prime number so it can no longer be simplified

Now we must convert it back to a mixed number

How many times does 3 evenly go into 692?

If you do long division or use a calculator, you'll notice 692 ÷ 3 = 230.6666666667

Disregarding the decimal values, 230 is how many times 3 goes evenly into 692

230 x/3

Now we must find the numerator

Since 3 evenly fits 230 times, multiply 3 and 230

3 × 230 = 690

This is not 692 so find the difference

692 - 690 = 2

This means the numerator value will be 2

230 2/3 is the answer
