Answer:

25.63694268 = r

Step-by-step explanation:

The circumference is

C = 2*pi*r

161 = 2*(3.14) *r

161 = 6.28 r

Divide each side by 6.28

161/6.28 = r

25.63694268 = r

Answer:

c = 10.5

Step-by-step explanation:

Formula: the product of the lengths of the segments of one chord equal the product of the segments of the other.

              a •d = c • b

               7*12 = c*8

                 84 =8c

Divide by 8

                 84/8 = 8c/8

                 10.5 = c

Answer:

Step-by-step explanation:

1) tan = opposite / adjacent

tan * adjacent = opposite

adjacent = opposite/tan

adjiacent = 60/1,600335 = 37.5

2) the two leg are congruent so the two angles are congruent

the sum of the inner angles of a triangle is 180 degrees

so

a = 45 degrees

b = 45 degrees

3) cos = adjacent/hypotenuse

adjacent = cos * hypotenuse

adjacent = 0,920505 * 45

adjacent = 41.4

Answer:

240

Step-by-step explanation:

5 150

-- -----

8 x

so you would then do 8 × 150 = 1200

then 1200 ÷ 5 = 240

so x = 240

Answer:

Step-by-step explanation:

Average rate of change of a function between interval x = a and x = b is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Average rate of change of the function in the interval [-4, -2]

= [tex]\frac{f(-2)-f(-4)}{-2-(-4)}[/tex]

= [tex]\frac{0-(-12)}{-2+4}[/tex]

= 6

Average rate of change in the interval [-2, 1]                                                                            

= [tex]\frac{f(1)-f(-2)}{1-(-2)}[/tex]

= [tex]\frac{3-0}{1-(-2)}[/tex]

= 1

Average rate of change in the interval [-3, 1]

= [tex]\frac{f(1)-f(-3)}{1-(-3)}[/tex]

= [tex]\frac{3-(-5)}{1+3}[/tex]

= 2

Average rate of change in the interval [-4, 0]

= [tex]\frac{f(0)-f(-4)}{0-(-4)}[/tex]

= [tex]\frac{4-(-12)}{0-(-4)}[/tex]

= 4

Answer:

Hi, there your answer is[tex]y=\frac{1}{2} x-4[/tex]

Step-by-step explanation:

Let's solve for y.

3x−6y=24

Step 1: Add -3x to both sides.

3x−6y+−3x=24+−3x

−6y=−3x+24

Step 2: Divide both sides by -6.

−6y /−6 = −3x+24 /−6

y=1/2x-4

Hope this helps :)

Answer:

A and E

Step-by-step explanation:

The ratio of the hypotenuse to the shorter leg to the longer leg is 2:1: root 3

Answer:

A. and E.

Step-by-step explanation:

The length of the hypotenuse is always double the length of the shortest leg and you can find the long leg by multiplying the short by the square of 3.

Answer:

I think it's 45, just guess bc ur in hurry

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Substitute the x- coordinate of the solution into each equation and if the value obtained is equal to the y- coordinate of the solution, then it is the equation.

A

y = - 2(4) + 4 = - 8 + 4 = - 4 ≠ 2 ← not the equation

B

y = - [tex]\frac{3}{4}[/tex] (4) + 5 = - 3 + 5 = 2 ← this is the equation

Thus (B) could be the equation of line n

Answer:

C

Step-by-step explanation:

convert option a to the lowest term

10 : 35 = 2: 7 (divide both ratios by 5)

8 : 28 = 2 : 7 (divide both ratios by 7)

convert option b to the lowest term

4 : 10 = 2 : 5  (divide both ratios by 2)

10 : 25 = 2 : 5  (divide both ratios by 5)

option c

divide 40km/h by 60 to convert to km / min

40/60 = 0.7 not equivalent

option d

determine cost of 1 litre

2.3/1.5 = 1.53

determine cost of 7.5 litres

1.53 x 7.5 = 11.5

Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.

Hence, the answer is $99.89.

Answer:

-16

Step-by-step explanation:

When adding a negative and a positive number, you need to keep in mind that your are essentially adding.

so if I have a number line

-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,

you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.

Answer:

D

Step-by-step explanation:

it is because each number is gotten by adding 12 to the previous number

Answer:

290.4 %

Step-by-step explanation:

Since 15 tons of grapes are picked and 1 ton = 2000 pounds, then 15 tons = 15 × 1 ton = 15 × 2000 lb = 30000 lb which is the mass of the grapes.

Since 1200 to 1300 gallons of wine are produced and we are to use 1250 gallons in calculations, since the density of wine, ρ = 8.262 lb/gallon, and ρ = mass of wine, m'/volume of wine, v = m/v

ρ = m/v

So, making m subject of the formula, we have

m = ρv

substituting the values of the variables into the equation, we have

m = 8.262 lb/gal × 1250 gal = 10327.5 lb

So, the yield percent for grapes to produce wine = mass of grapes/mass of wine × 100 %

= 30000 lb/10327.5 lb × 100 %

=  2.904 × 100 %

= 290.4 %

So, the yield percent for grapes to produce wine is 290.4 %

Answer:

16

Step-by-step explanation:

4 option: Pork, chicken, beef, or veggie burritos.

Pork with beans

pork with hot salsa

pork with mild salsa

etc.

Pork: 4 possibility

Answer:

4, 12, 36, 108

Step-by-step explanation:

a1: 4(3)^1-1 = 4(3)^0 = 4

a2: 4(3)^2-1 = 4(3)^1 = 12

a3: 4(3)^3-1 = 4(3)^2 = 36

a4: 4(3)^4-1 = 4(3)^3 = 108
