The diameter of a circle measures 18ft what is the circumference of the circle? Use 3.14 for π and do not round

Answer:

three (3).

Step-by-step explanation:

H=O+A

c^2=5^2+12^2

c^2=25+144

c^2=169

c=√169

c=13

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

Let's calculate the value of c using Pythagoras theorem ~

[tex]\qquad \sf  \dashrightarrow \: c {}^{2} = a {}^{2} + {b}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: c {}^{2} = {5}^{2} + {12}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: c = \sqrt{25 + 144} [/tex]

[tex]\qquad \sf  \dashrightarrow \: c = \sqrt{169} [/tex]

[tex]\qquad \sf  \dashrightarrow \: c = 13 \: units[/tex]

Answer:

<4 = 67 degrees

Answer:

Hamburger is 320 calories. Pack of french fries is 280 calories

Step-by-step explanation:

Represent Hamburgers as H and pack of French Fries as P then set up the equations

5H+2P=2160

4H+5P=2680

Multiply the first equation by 5

25H+10P=10,800

Multiply the second by 2

8H+10P=5360

Subtract the first equation by the second

25H+10P=10,800

-

8H+10P=5360

=

17H=5440

H=320

One hamburger is 320 calories.

Plug in 320 for H

5(320)+2P=2160

1600+2P=2160

2F=560

F=280

One pack of french fry is 280 calories

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.

The area of a rectangle is given as the product between the length and it's width.

Data;

[tex]area = length * width[/tex]

In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as

[tex]A = length * width\\width = \frac{area}{length} \\width = \frac{45}{9} \\width = 5in[/tex]

We can see that the width are not equal so is their length.

But if we would truly compare them, the accurate way to do that is by their area

The area of the second gauze is given by

[tex]a = 3 * 4 = 12in^2[/tex]

From the above calculations, we can see that the sheets are not similar as they have different areas.

Answer: Two triangles have the same side lengths (Ex: both triangles have sides 3, 4, and 5 cm)

Step-by-step explanation:

1) This would guarantee similarity, but not necessarily that they are identical.

2) The angle has to be included between the two sides, which is not specifed.

3) This would work (SSS congruence)

4) It is not specified if the side is opposite the corresponding angles.

If he starts paying after four years, the worth of the loans by then is b. $31,616.16

This refers to the amount collected from a lender to be repaid after a given time, usually with added interest.

Hence, we can see that:

The effective monthly interest rate is:

i = 0.053/12 = 0.0044

The effective annual interest rate is:

i = (1 + 0.0044)^12 -1 = 0.0543

The present worth of all the loans is:

P = 6125 + 6125 (1 + 0.0543)^-1 + 6125 (1 + 0.0543)^-2 + 6125(1 + 0.0543)^-3

P = $22,671.40

If he pays them prompty, then the total lifetime cost would be

P = 22671.40 (1 + 0.0543)^4 = $31,616.16

Answer:

63

Step-by-step explanation:

the sum of the interior angles of a triangle is 180

so,

70+47= 117

180-117= 63

Answer:

Your answer is 63°

Explanation:

47 + 70 + angle C = 180° (Sum of all angles of a triangle is 180).

117 + angle C = 180°

So,angle C =180 - 117= 63°

Step-by-step explanation:

Let [tex]X[/tex] denote the observed value of this game. Let positive values denote money received and negative values denote money paid.

There are two possible values for [tex]X[/tex]:

The probability of each value is:

The expected value of this game, [tex]\mathbb{E}(X)[/tex], is an average of the outcomes [tex]x \in \lbrace 10,\, -2\rbrace[/tex] weighted by the probability [tex]P(X = x)[/tex] of each outcome:

[tex]\begin{aligned}\mathbb{E}(X) &= \sum\limits_{x} x\, P(X = x) \\ &= 10 \times P(X = 10) + (-2) \times P(X = -2) \\ &= 10 \times \frac{1}{10} + (-2) \times \frac{9}{10} \\ &= 1 - 1.8 \\ &= -0.8\end{aligned}[/tex].

The expected value of [tex]X[/tex] is [tex](-0.8)[/tex], meaning that on average, playing this game would require paying [tex]\$0.8[/tex].

Answer:

27565541.

Step-by-step explanation:

The volume of the unit cell that is a simple cubic is 1.1661622e⁻²⁰.

Volume is the space occupied by a three-dimensional object.

By the formula of volume of atom

[tex]\rm Volume(atom) = \dfrac{4}{3} \times \pi \times r^3\\Volume(atom) = \dfrac{4}{3} \times \pi \times (161 \times 10^-^2^3)^3\\Volume(atom) = 2.1574e^-^2^1[/tex]

There are total 4 atoms, in a  FCC unit cell.

The total volume is

[tex]2.1574e-21 \times 4 = 8.6296e^-^2^1[/tex]

Volume of a unit cell will be

[tex]\dfrac{8.6296e-21}{0.74} = 1.1661622e^-^2^0[/tex]
