Find the area of a circle with a diameter of 2 feet use 3.14 use pi Also please say all the. steps if you can​

Answers

Answer 1

Given:

Diameter of a circle = 2 feet

To find:

The area of a circle.

Solution:

We know that, area of a circle is

[tex]A=\pi r^2[/tex]

Where, r is the radius of the circle.

Diameter of a circle = 2 feet

So, radius of the circle = [tex]\dfrac{2}{2}=1[/tex] feet

Putting r=1 and [tex]\pi=3.14[/tex] in the above formula, we get

[tex]A=(3.14)(1)^2[/tex]

[tex]A=(3.14)(1)[/tex]

[tex]A=3.14[/tex]

Therefore, the area of the circle is 3.14 sq. feet.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Using sin ratio to find the value of x:

sin45 = X/1

1/√2 = X/1

X = (1/√2)(√2/√2)

X = √2/2

Thus, the length of the side is 1/√2 or √2/2 units after applying the sin ratio.

simplify the expression -6 - 7 (c+10)

Answers

Answer:

[tex]-6-7\left(c+10\right)=-7c-76[/tex]

Step-by-step explanation:

Given the expression

[tex]-6\:-\:7\:\left(c+10\right)[/tex]

simplifying the expression

[tex]-6-7\left(c+10\right)[/tex]

Expanding -7(c + 10) = -7c - 70

[tex]-6\:-\:7\:\left(c+10\right)=-6-7c-70[/tex]

subtract the numbers: -6 - 70 = -76

Lines j and k are parallel. They are intersected by the transversals, l and m.

Answers

Answer:72

Step-by-step explanation:

72 and the angle to the top right of x are corresponding angles. This means they are the same. Using this, we can see that the same angle to the top right of x that we now know is 72 is also vertical to x. Vertical angles are also equal, so x = 72

The value of x is 72°

Parallel lines:

Parallel lines are lines in the same plane and of the the same distance.

The parallel line j and k are intersected by the transversals l and m.

Therefore, corresponding angles, alternate angles etc. can be formed.

Since the pair of parallel lines are cut by the transversal lines then the alternate exterior angles are congruent . Therefore,

x = ∠72°

∠x ≅ ∠72°(alternate exterior angles)

Last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.
Last week at the park, what was Heather’s rate of speed in miles per hour? Use words and/or numbers to explain your answer.​

Answers

Answer:

she ran 10 miles a hour

Step-by-step explanation:

she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10

Heather's rate of speed last week was 1/12 miles/min.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.

Heather's rate of speed last week -

{r} = 4/48 = 1/12 miles/min

{r} = 1/12 miles/min

Therefore, Heather's rate of speed last week was 1/12 miles/min.

I need to step-by- step ways on how this is or isn’t a solvable equation. Please HELP

Answers

Answer:

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true
