Answer:

25.12 inches

Step-by-step explanation:

Given that,

→ Diameter = 8 in

→ Radius (r) = 8/2 = 4 in

→ π = 3.14

Formula we use,

→ 2πr

Then the circle's circumference is,

→ 2πr

→ 2 × 3.14 × 4

→ 2 × 12.56

→ [ 25.12 in ]

Thus, circle's circumference is 25.12 in.

f(5) = 254

We are given the statement that, If P is any odd number, then P + 2 is a prime number and we need to prove it either false or true, so as here it is written "any", so it means that the statement should be true for every and each odd number

⇒ P + 2 = 3 ↔ True

⇒ P  + 2 = 5 ↔ True

⇒  P + 2 = 7 ↔ True

⇒ P + 2 = 9 ↔ False

The given statement becomes false for P = 7, so the given statement is false

Answer: Graph C

Step-by-step explanation:

y-2 < -2x+2

y<-2x+4

slope is negative so it goes down. y int is 4.

insert (0, 0) into equation and 0 < 4 is true so shade where the origin is.

Step-by-step explanation:

Cost prevents one of the biggest barriers to restaurants offering healthier menu options. Fast-food chains like McDonald's have made their fortune by offering food with a long shelf life, which tends to be less healthy. As pointed out in The New Yorker, even if every restaurant in America decided to drop the fries and embrace kale and watermelon radish salads, the U.S. lacks the agricultural infrastructure to support that kind of dietary shift. Big farm crops like soybeans (for frying oil), corn (for high fructose corn syrup), and grain (livestock feed) receive millions of tax breaks and other government subsidies, making it hard for smaller farms to compete.

Answer:

[tex]y=-\dfrac{300}{7}x+1000[/tex]

Step-by-step explanation:

Method 1  (see attachment 1 with red line)

Plots the points on a graph and draw a line of best fit, remembering to ensure the same number of points are above and below the line.

Use the two end-points of the line of best fit to find the slope:

[tex]\textsf{let}\:(x_1,y_1)=(0,1000)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(7,700)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{700-1000}{7-0}=-\dfrac{300}{7}[/tex]

Input the found slope and point (0, 1000) into point-slope form of a linear equation to determine the equation of the line of best fit:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-1000=-\dfrac{300}{7}(x-0)[/tex]

[tex]\implies y=-\dfrac{300}{7}x+1000[/tex]

Method 2  (see attachment 2 with blue line)

If you aren't able to plot the points, you should be able to see that the general trend is that as x increases, y decreases.  Therefore, take the first and last points in the table and use these to find the slope:

[tex]\textsf{let}\:(x_1,y_1)=(1,940)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(7,710)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{710-940}{7-1}=-\dfrac{115}{3}[/tex]

Input the found slope and point (1, 940) into point-slope form of a linear equation to determine the equation of the line of best fit:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-940=-\dfrac{115}{3}(x-1)[/tex]

[tex]\implies y=-\dfrac{115}{3}x+\dfrac{2935}{3}[/tex]

Answer: [tex]y=\frac{7}{2} x+10[/tex]

Step-by-step explanation:

y=mx+b

b=the y intercept

m=slope

In this graph, the y intercept is 10 so we can substitute b for that.

You find the slope with 2 points on the line.

(2,17) (6,31)

[tex]\frac{31-17}{6-2}[/tex]=[tex]\frac{14}{4}[/tex] which is simplified to [tex]\frac{7}{2}[/tex]

You can substitute m for [tex]\frac{7}{2}[/tex] now and your equation is [tex]y=\frac{7}{2} x+10[/tex]

Answer:

= [tex]\frac{0.423}{1}[/tex]

=[tex]\frac{423}{1000}[/tex]

so the answer is 423/1000

Answer:

Mean=49 pounds

Median=11pounds

Step-by-step explanation:

If all the cats got weighted (5, 11,11,12,10) for each cat you need to add, multiply and divide to get all the answers (P.S. you don't need to round for your answers!)

For solving the Mean you need to add up all the numbers and then divide by how many numbers there are (5+11+11+12+10÷ 5=49)

For solving the Median you need to put the numbers in smallest to biggest order to solve for this (5,10,11,11,12) and then kept crossing them out (left to right) until you get the two middle numbers (11,11) then add them both right and then divide 22 by 2 then you have your answer!

You're going to rock this:)

8r+72

Step-by-step explanation:

Answer:

8r + 72

Step-by-step explanation:

you multiply 8 by each number(or letter) in the parentheses, so 8 * r is basically 8r, and 8*9 is 72

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

[tex]\textrm{Slant height l} = \sqrt{r^2 + h^2}[/tex]  (1)

[tex]\textrm{Lateral surface area} = \pi r l[/tex]

[tex]\textrm {Base area} = \pi r^2[/tex]

[tex]\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)[/tex] (2)

[tex]\textrm{Volume V = } (1/3) \pi r^2h[/tex] (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

[tex]\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04[/tex]

Figure(b)

r = 7, h =15

[tex]\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55[/tex]

[tex]\textrm{SA} = 7\pi(7 + 16.55) = 517.89[/tex]

Figure (c)

r = 5, l = 8

[tex]h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5[/tex]
