Find the area of a circle in feet with the radius being 3'.

Answers

Answer 1

Answer:

28.27 ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius

Plug in 3 for the radius

[tex]A=\pi (3)^2\\A=9\pi[/tex]

[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)

Therefore, the area of the circle is 28.27 ft².

I hope this helps!

Answer 2

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Step-by-step explanation:

An area cannot be in feet. It must be in a square unit such as square feet.

A = r²

A = ()(3 ft)²

A = 9 ft²

A = 9(3.14159) ft^2 = 28.3 ft²

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)

Answers

Answer:

Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true

Step-by-step explanation:

We are given two expressions:  x -3 and y  - 3

Here x and y are two different variables.

These expressions are equal, when the value of x and the value of y are equal.

x - 3 = y -3 if x = y.

Therefore, the two expressions have the same value in sometimes.

That is, when x = y, then the value of two expressions are the same.

Example.

If x = 2 and y = 2, then

x - 3 = y - 3

2 - 3 = 2 - 3

-1 = -1

If they have different values, for x =  2 and y = 3

x - 3 = y - 3

2 - 3 = 3 -3

-1 = 0

Which is not true.

Therefore, the answer is sometimes.

Which measurement is the same length as 1 meter

Answers

Answer:

3 feet

Step-by-step explanation:

From the option available the measurement 1 meter is equal to 100 centimeters.

What is unit conversion?

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

given the measurement is 1 meter

1 meter is equal to 100 centimeters

From unit conversion:

1 meter is also equal to 3.2808 feet

1 meter is also equal to 39.3701 inch

1 meter is also equal to 1000 millimeters

1 meter is also equal to 1.093 yards.

you save $15 per week to purchase a bike that costs $120. write and solve an inequality to find the number of weeks you need to save to purchase the bike.

Answers

Answer:

Must save 8 weeks or more to purchase the bike.

Step-by-step explanation:15*w >= 120 where W is the number of weeks.

w >= 120/15 = 8

You need to save $15 every week for the next 8 weeks in order to purchase the bike.

What is inequality in mathematics?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is that you save $15 per week to purchase a bike that costs $120.

Assume that you need [w] weeks to save $120 for the bike.

Amount earned per week [A] = $15

Amount earned in [w] weeks [W] = $15w

Money needed [R] = $120

The inequality can be written as -

[W] ≥ [R]

We can write it as -

15w ≥ 120

Solving the inequality, we get -

15w/15 ≥ 120/15

w ≥ 8

Therefore, you need to save $15 every week for the next 8 weeks in order to purchase the bike.

HELP ASAP!!! Make t the subject of 5(t − g) = 2t + 7

Answers

Answer:

t=(7+5g)/3

Step-by-step explanation:

5(t-g)=2t+7

5t-5g=2t+7

5t-2t=7+5g

3t=7+5g

divide both side by 3

t=(7+5g)/3

As per linear equation, the variable 't' is subject of 5(t -g) = 2t + 7 as  [tex]t = \frac{5g + 7}{3}[/tex].

What is a linear equation?

"A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.

There are linear equations in one variable and linear equations in more than one variable. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

The given linear equation is:

5(t - g) = 2t + 7

We can calculate the value of the variable 't' by keeping it in the left hand side of the equation and then rest of the elements on the right hand side of the equation. Now we get:

⇒ 5t - 5g = 2t + 7

⇒ 5t - 2t = 5g + 7

⇒ 3t = 5g + 7

⇒ [tex]t = \frac{5g + 7}{3}[/tex]

Therefore, the value of the variable 't' in terms of the variable 'g' is  [tex]t = \frac{5g + 7}{3}[/tex].
