An Experienced ice skater spins on the ice, creating a perfect circle with a diameter of 4 feet. What is the circle's radius?

Answer:

272 square inches

Step-by-step explanation:

Given

[tex]l = 8[/tex] --- length

[tex]w = 2[/tex] --- width

[tex]h = 12[/tex] ---- height

Required

Determine the total surface area (SA)

This is calculated using:

[tex]SA = 2 * (lw + wh + lh)[/tex]

[tex]SA = 2 * (8*2+2*12+8*12)[/tex]

[tex]SA = 2 * 136[/tex]

[tex]SA = 272[/tex]

The total surface area is 272 square inches

Answer:

A = 173.82

Step-by-step explanation:

[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]

a = 6

substitute 6 for a

A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]

solve:

A = 2 (1 + [tex]\sqrt{2}[/tex]) 36

A = 173.82

Answer:

Around 173.8 km (rounded to the nearest tenth of a km

Step-by-step explanation:

The area of an octagon can be found using the expression:

A=2(1+sqrt of 2)a^2

plug your side of 6 in to create the following equation:

A=2(1+sqrt of 2)(6^2)

Solve for A:

A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.

A=72+72sqrt of 2

plug that in a calculator and you get around 173.8 km

Answer: 11

Step-by-step explanation:

When you do square root, you're just finding the number that can be multiplied by itself to get what's inside the √ .

So, when you do √121 , you'll get 11. You can check your answer by going backwards: multiply 11 by itself.

[tex]15^2-4^2=225-16\\=209[/tex]

[tex]\sqrt{209}[/tex]≈14.9

Answer:

14.5

Step-by-step explanation:

15x15=225

4x4=16

225-16=209

The square root of 209 is 14.4568322948.

A. y≥4x+5

B. y>4x-5

C. y>-4x-5

Answer:

4.5 hours

Step-by-step explanation:

distance equals rate times time, a relationship that can be solved for time:

time = distance / rate

Here the time is (135 miles) / (30 mph) = 4.5 hours

The bus requires 4.5 hours to get to the museum.

Step-by-step explanation:

(-7+1)/(5-1)=-6/4= -3/2 is the slope

answer is C

Answer:

C

Step-by-step explanation:

The formula for slope is rise/run

Rise is the difference between the y coordinates

Run is the difference between the x coordinates

To find the rise and run:

ex.

(a, b), (c, d)

rise:

d-b

run:

c-a

Slope:

d-b/c-a

In this situation:

rise:

-7-(-1)

run:

5-1

Slope:

-7-(-1)/5-1

= -6/4

=-3/2

So the answer is C

x=11 should be the answer lmk if so

Answer:

x = 18

Step-by-step explanation:

m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.

It is given that:

m∠1 = 4x - 14

m∠3 = 58°

Set the two angles equal to each other:

4x - 14 = 58

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 14 to both sides of the equation:

4x - 14 (+14) = 58 (+14)

4x = 72

Next, divide 4 from both sides of the equation:

(4x)/4 = (72)/4

x = 72/4 = 18

18 is your answer for x.

Answer:

both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately

log(x) - log(6) = 2 log(4)

Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):

log(x / 6) = 2 log(4)

Rewrite the right side, using the property n log(a) = log(aⁿ ):

log(x / 6) = log(4²)

log(x / 6) = log(16)

Cancel the logarithms (i.e. take the exponential of both sides):

exp(log(x / 6)) = exp(log(16))

x / 6 = 16

Solve for x :

x = 6 × 16

x = 96

(0.5 , -1.5)

Step-by-step explanation:

intersection of their diagonals (E): right at the mid-point of segment AC or BD

A (5 , 0)  and C (-4 , -3): E (x , y)

x = (5 + -4 ) / 2 = 0.5

y = (0 + -3 ) / 2 = - 1.5

E ( 0.5 , - 1.5)

check with BD: x = (3 + -2) / 2 = 0.5        y = (-3 + 0) / 2 = - 1.5

Answer:

By angle sum property,
