How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer:

A. 18.84

B. 28.26

C. 364.24

D. 120

E. 14

F. 21

G. 96

CODE: 1977.98

Step-by-step explanation:

a. C = 2πr

C = 2π(3)

C = 6π

C = 6(3.14)

C = 18.84

b. A = πr²

A = π(3)²

A = 9π

A = 9(3.14)

A = 28.26

c. C = 2π(58)

C = 116π

C = 116(3.14)

C = 364.24

d. 4x + 2x = 180

6x = 180

x = 30

4x = 4(30) = 120

e. 3x - 21 = x + 7

2x = 28

x = 14

f. angle JHK = 3x - 21 = 3(14) - 21 = 21

g. supplementary means 2 numbers add up to 180

180 - 84 = 96

CODE: E(C - D) - F(G - B) - A

14(364.24 - 120) - 21(96 - 28.26) - 18.84

= 14(244.24) - 21(67.74) - 18.84

= 3419.36 - 1422.54 - 18.84

= 1977.98

A recent conference had 650 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?

There were about 167 principals in attendance.
There were about 316 principals in attendance.
There were about 483 principals in attendance.
There were about 1,878 principals in attendance.

Answers

So first you divide 650 by 70 so that you know how many rooms there are. The answer is about 9. Then you multiply 9 by the number of principals, so that you know how many principals there are in total. 52x9= about 483. This means the answer is that there were about 483 principals.

There were about 483 principals in attendance.

The correct option is (3).

What is Arithmetic?

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data:

The total number of people in the recent conference = 650

The total number of people in one exhibit room = 70

Number of teachers in one exhibit room = 18

Number of principals in one exhibit room = 52

To find out the total number of exhibit rooms:

= Total number of people in the conference / total people in one room

= 650 / 70

= 9.28 = 9 {rounding off to the nearest integer}

Number of principals in one exhibit room = 52

Total number of principals in the conference:

= Number of rooms × Principals in one room

= 9 × 52 = 468 which is equal to 483 {approximate answer}

There were about 483 principals in attendance.

Hence, There were about 483 principals in attendance.

b) The correct expression is given as follows: -8.6b + 28.

How to simplify the expression?

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5
