Find the radius of a circle with a circumference of 28 pie

Answer:

I think the correct answer is the last one: 80<67+4g

Step-by-step explanation:

a)

[tex]\sin^{2}x + \cos^{2}x = 1[/tex]

Dividing both sides by sin^2x, we get

[tex]1 + \frac{\cos^{2}x }{ \sin^{2}x} = \frac{1}{\sin^{2}x } [/tex]

The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x

[tex]1 + \cot^{2}x = \csc^{2}x[/tex]

b)

[tex]2 \sin x = 1[/tex]

[tex] \sin x = \frac{1}{2} [/tex]

[tex]x = \sin^{ - 1} (\frac{1}{2}) = \frac{\pi}{6} [/tex]

You can also graph it to arrive at the solution.

Time taken to elapse the remaining $861  = 10.25 days

Step-by-step explanation:

Assuming that I am spending at a rate of -x dollars per day

Let initial amount be A

The rate of expenditure = 1281-861/5 = 84 dollars per day

Time taken to elapse the remaining $861 = $861/$84 per day

= 10.25 days

The surface area of a cylinder with the given dimensions is 571.48 [tex]cm^2[/tex].

Step-by-step explanation:

To find the surface area, you need to use the formula [tex]2\pi r^2 + h * 2\pi r[/tex] where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height. In this problem, the expression would be [tex]7^2 * 3.14 * 2 + 3.14*14*6[/tex] = [tex]49 * 6.28 + 3.14 * 84[/tex] = [tex]307.72+263.76[/tex] = 571.48 [tex]cm^2[/tex].

Answer:

yes

Step-by-step explanation:

Mathematically, C’ = πd’

C’ =16, π = 22/7

∴ 16 = 22d’/7

16 x 7 = 22d’

d' = (16 x 7) / 22

d’ = 112/22

d’ = 5.09

d d’ = 0.25

d’ = 5.09

∴ d (5.09) = 0.25

d = 0.25/5.09

d = 0.05

Mathematically, C = πd

π = 22/7, d = 0.05

∴ C = 22/7 x 0.05

C = 0.16

Answer:

3/5

Step-by-step explanation:

3+2=5. 3/5 is the blue marble. You may also say 6/10. It is likely you will pull out a blue marble.

probability that the blue marble was chosen both times 6/10.

It is a branch of mathematics that deals with the occurrence of a random event.

Jar contains 3 blue marbles.

Jar contains 2 red marbles.

Total marbles= 5

If she replaced a marble and second time she choose a marble gets blue.

Then, probability of blue marble= 3/5.

But for both the probability for both instance will be 3/5 i.e.,

=  3/5*2/2

= 6/10

Hence, probability that the blue marble was chosen both times 6/10.

Answer:

145

Step-by-step explanation:

angles in a pentagon add up to equal 540

Hence, 110 + 90 + 80 + 115 + v = 540

( note that we just created an equation that we can use to solve for v )

We now solve for v using the equation created

110 + 90 + 80 + 115 + v = 540

step 1 combine like terms

110 + 90 + 80 + 115 = 395

we now have 395 + v = 540

step 2 subtract 395 from each side

540 - 395 = 145

395 - 395 cancels out

we're left with v = 145

The estimated probability that at least one of the next four fish Roxanne catches will be a trout will be 60%. Then the correct option is B.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

The simulation result shows at least one of the next four fish Roxanne catches will be

(2635, 2053, 4526, 6994, 4348, 3087, 8323, 3579, 3840, 6389, 3363, 7683)

The number of simulation results showing at least one of the next four fish Roxanne catches will be 12.

The total number of simulation results is 20.

Then the probability will be

P = 12/20

P = 0.6

P = 60%
