Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Step-by-step explanation:

First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.

Question 17

Using a calculator, you get 6.48074069… for your decimal.

Rounding it to the nearest tenth, your answer would be 6.5

Now, to find the two consecutive whole numbers the square root is between…

However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.

Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!

Question 18

Using a calculator, you get 9.380833151… for your decimal.

This rounds to 9.4

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.

In non-decimal form (simplified radical), your answer can be 2√22.

Question 19

Using a calculator, you get 7.93725393… for your decimal.

This rounds to 7.9

The whole numbers surrounding this decimal are 7 and 8.

You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.

In non-decimal form (simplified radical), your answer can be 3√7.

Question 20

Using a calculator, you get 8.66025403… for your decimal.

This rounds to 8.7

The whole numbers surrounding this decimal are 8 and 9.

You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.

In non-decimal form (simplified radical), your answer can be 5√3.

Question 21

Using a calculator, you get 5.47722557… for your decimal.

This rounds to 5.5

The whole numbers surrounding this decimal are 5 and 6.

You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.

Question 22

Using a calculator, you get 9.84885780… for your decimal.

This rounds to 9.8

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.

Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.

Answer:

952 cubic feet

Step-by-step explanation:

The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.

Step-by-step explanation:

Speed is the rate of motion, or the rate of change of position. It is expressed as distance moved (d) per unit of time(t). Speed is a scalar quantity with dimensions distance/time. Speed is measured in the same physical units of measurement as velocity, but does not contain an element of direction. Speed is thus the magnitude component of velocity. Velocity contains both the magnitude and direction components.

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:

Part A

12.6 - 0.4x = y

Part B

x = 31.5

Step-by-step explanation:

Part B

12.6 ÷ 0.4 = 31.5 hours

y=12.6-0.4x is the required linear equation and it takes 31.5 hours to completely evaporate the water in glass.

Two or more expressions with an Equal sign is called as Equation.

Given that in the beginning of the experiment, the water level is 12.6 cm.

The water level in a glass decreases 0.4 cm each hour

Let x represent time, in hours, elapsed since the beginning of the experiment and let y represent the water level, in centimeters.

We need to find the linear function, using x and y from above, that determines the water level at a given time, in hours, after the experiment begins.

y=12.6-0.4x

We need to find how long will it take to for all of the water to evaporate.

12.6/0.4 = 31.5 hours

Hence, y=12.6-0.4x is the required linear function and it takes 31.5 hours to completely evaporate the water in glass.

The total distances you traveled to reach your destination on each day of your three-day trip are as follows:

a) Day 1 = 40 miles

b) Day 2 = 30 miles

c) Day 3 = 11 miles.

The total distances are determined using proportions.

Proportion refers to the fractional value of the whole number or quantity.

a) Day 1:

The fractional distance traveled = ⁵/₈

The remaining distance to travel = 15 miles

15 miles = ³/₈ (1 - ⁵/₈)

Proportionately, the total distance = 40 miles (15 ÷ ³/₈)

b) Day 2:

The distance traveled = 18 miles

The remaining distance to travel = ²/₅

The distance traveled = ³/₅ (1 - ²/₅)

³/₅ = 18 miles

Proportionately, the total distance = 30 miles (18 ÷ ³/₅)

c) Day 3:

The distance traveled = ⁵/₁₁

The distance to travel = 6 miles

The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)

Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Answer:

x = 1,200 + 1,200(0.025)(0.75)

Step-by-step explanation:

The initial deposit of $1,200 is added to the total amount in the account after 9 months, so we start with 1,200 + ?

The annual interest rate is 2.5%, but we need to calculate the interest earned in 9 months. To do this, we can multiply the annual rate by the fraction of the year represented by 9 months, which is 0.75 (9/12). So the interest earned is 1,200(0.025)(0.75).

Adding the interest earned to the initial deposit gives us the total amount in the account after 9 months, which is x.

Answer:

C

Step-by-step explanation:

Seeing has his initial deposit is 1200

We first convert 2.5% to a decimal making it 0.025 because we moved the decimal 2 places back seeing as 100 percent only has 2 0s

It's also asking us how much money is in his account in 9 months meaning we have to times it by 9 and not 0.75

Step-by-step explanation:

1÷1/4 = 1✕4/1 = 1✕4 = 4

The expression is A = 4 and the real life application is solved

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists  mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

Given data ,

Let the expression be represented as A

Now , the value of A is

A = 1 / ( 1/4 )

A = 1 x 4 = 4

Now , A real-life application of the expression 1÷1/4 is calculating how long it would take to complete a task if you can complete 1/4 of it in one hour. For example, if you can clean 1/4 of a room in one hour, you can use this expression to calculate how long it would take you to clean the whole room.

1 ÷ 1/4 = 1 x 4/1

On simplifying the equation , we get:

1 ÷ 1/4 = 4

Hence , if you can complete 1/4 of a task in one unit of time, you can complete the entire task in 4 units of time. In the example of cleaning a room, if you can clean 1/4 of the room in one hour, it would take you 4 hours to clean the entire room.
