Answer and Step-by-step explanation:

First, we need to find out the circumference of the circle.

We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.

2[tex]\pi[/tex]r

Plug in 1 for r.

[tex]2\pi (1)[/tex] = [tex]2\pi[/tex] = circumference of circle

Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.

[tex]2\pi[/tex] x 4 = [tex]8\pi[/tex] = perimeter of square

Now, divide the perimeter by 4 to get what the side of the square is.

[tex]8\pi[/tex] ÷ 4 = [tex]2\pi[/tex]

Now, multiply [tex]2\pi[/tex] by [tex]2\pi[/tex] (side times side) to get the area.

[tex]2\pi[/tex] x  [tex]2\pi[/tex] = [tex]4\pi[/tex]

The answer is A. [tex]4\pi[/tex]

Answer:

w=-7/2z

Step-by-step explanation:

to solve for w you firstly have to group the like terms

5w-3w=2z-9z

2w=-7z

then you have to divide both sides by 2 inorder to remain with w on one side.

2w/2=-7/2

w=-7/2

Answer:

13 units

Step-by-step explanation:

Using the right triangle formed by the 2 legs and the slant height s

The legs are 12 and 10 ÷ 2 = 5, with hypotenuse s

Using Pythagoras' identity in the right triangle, then

s² = 12² + 5² = 144 + 25 = 169 ( take the square root of both sides )

s = [tex]\sqrt{169}[/tex] = 13

Answer:

C

Answer:

Let n be the total number of desserts.

Let s be the total ounces of  strawberries.

S = 4n <- answer to part a.

24 = 4n

n = 6

If she has 24 ounces of strawberries, she can make 6 desserts.

Answer:

380 miles

Step-by-step explanation:

Let the time he travelled on the second day = t

Then the first day's time is t + 2

The first day's distance is d+20

The second day's distance is d

The second day's distance is also 60*t or d = 60*t

First day: 40*(t+2)  = d + 20

Put the second day's distance into the first day's equation

40(t+ 2) = 60t + 20       Now solve for t. Remove the brackets

40*t + 80 = 60t + 20    Subtract 20 from both sides

40t + 80 - 20 = 60t      Combine

40t + 60 = 60t              Subtract 40t from both sides

60 = 60t - 40t

60 = 20t                       Divide by 20

t = 60 / 20

t = 3

Day 2s distance = 60*3 = 180

Day 1s distance = 40*5  =200

Total                                  380

You may ask where the 20 went. It is a fact relating the distance of day 1 with day 2. No one actually travelled the 20 miles. It is just that there is a difference of 20 miles in the two distances.

The Constructed  confidence interval for the proportion of her photographs taken within the last year contained flowers is

[tex]CI\ E(0.57,0.65)[/tex]

From the question we are told that:

The proportion of photographs that had flowers P= 0.61

Margin of error of M.E= 0.04

Generally, the equation for Confidence interval for proportion is mathematically given by

[tex]CI=0.61 \pm 0.04[/tex]P \pm M.E

Therefore Confidence interval is

[tex]CI=0.61 \pm 0.04[/tex]

And can also be written as

[tex]CI\ E((0.61+0.04),0.61-0.04))[/tex]

[tex]CI\ E(0.57,0.65)[/tex]

In conclusion the Confidence interval is

[tex]CI\ E(0.57,0.65)[/tex]

Answer:

C = 8 pi cm

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

16 pi = pi r^2

Divide each side by pi

16 = r^2

Taking the square root

4 = r

The circumference is

C = 2 * pi *r

C = 2* pi *(4)

C = 8 pi cm

Answer:

x = 90

Step-by-step explanation:

Here 60 is angle B, 30 is Angle a, B is The third angle of the triangle, and x is the exterior angle measurement!

60 + 30 + b= 180

a + x = 180

60 + 30 + b= 180

90 + b = 180

b = 90

90 + x = 180

x = 90

exterior angle  equal to the sum of its two opposite non-adjacent interior angles.
