Answer:

113.1 (113.09734)

Step-by-step explanation:

The equation for the volume of a sphere:

[tex]v = \frac{4}{3} \pi r^{3}[/tex]

v for volume; r for radius

if r (radius) = 3

then

v = 4/3 x pi x 3^3

v = 113.09734

v =(about) 113.1

How many years of good luck are we talking about?

It would be 12.2 lbs per package

Since 24.4/2 = 12.2

It would be 97.6 lbs. for 8 packages

122 lbs. would equal out to be 10 packages.

Answer:

q=(40-7)/3 or simplified q=11

Step-by-step explanation:

So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.

Answer:

Step-by-step explanation:

the sides are 3×5, 3×2, and 2×5, and there are two of each. 3×5 is 15, 3×2 is 6, and 2×5 is 10.

we need to find 15×2, which is 30, 6×2, which is 12, and 10×2 which is 20. then we need to add all of these together, which is 62

Step-by-step explanation:

To find the solution of the inequality given, we must isolate the variable.

Simplifying the RHS:

Hence, the variable 'y' must be below than 0 to make this statement true.

Explanation:

9 yellow

9 red

9+9 = 18 total

If you select a marble at random, the chances of it being yellow are 9/18.

If you selected another marble at random, without replacing the first marble, then 8/17 is the probability of getting another yellow marble. I subtracted 1 from the numerator and denominator of 9/18 to go to 8/17.

We multiply the two results

(9/18)*(8/17) = 0.235 approximately

There's roughly a 23.5% chance of getting two yellow in a row, where we don't replace the first marble selected.

Answer:

s = r - 5.25

4r = 6s

Step-by-step explanation:

s = the sale price of the coffee

r = the regular price of the coffee
s = r -5.25 : sale price of the coffee equal the regular price minus 5.25 (on sale)

4r = 6s : 4 bags of regular coffee equals 6 bags at sale price

Answer: 1330

Just subtract the tax from the price...

Answer:

No

Step-by-step explanation:

Use the pythagorian theorm to find whether it's a right triangle or not.

So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared

5.2 squared= 2.4 squared+ 4m5 squared

27.04= 26.01

It's not equal so the triangle isn't a right triangle.

Answer:

Well you can start by dividing 20 by 2 because that would give you the half that you finished in class 24 divided by 2 =12 if you finish four more you wound have 12-4=8 you have 8 problems left and now you have to find the fraction so start with 8/24 and then simplify your answers would be 1/3

Answer:

c) 13

Step-by-step explanation:

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {5}^{2} + {12}^{2} = {c}^{2} \\ 25 + 144 = {c}^{2} \\ 169 = {c}^{2} \\ c = 13[/tex]

Answer:

C) 13

Step-by-step explanation:

Using the formula: [tex]a^{2} +b^{2}=c^{2}[/tex], we can plug in 5 into a and 12 into b, since c is always the hypotenuse. Plug those numbers into the formula: [tex]5^{2} + 12^{2} =c^{2}[/tex] and you get 25 + 144 = [tex]c^{2}[/tex] or 169 = [tex]c^{2}[/tex]. You can then get rid of the square on the c by finding the square root of both sides. So, the square root of 169 would give you the answer of 13.

Answer:

x= 4, y= -1

Step-by-step explanation:

-2(x +3y= 1)

-2x-6y=-2

2x -5y= 13

-11y= 11

y= -1

2x -5(-1)= 13

2x +5= 13

2x= 8

x= 4

Answer:

If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.

the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).

Step-by-step explanation:

The  probabilities of getting :

O Threes is 0.48

1 Three is  0.095

2 Threes is 0.019

3 Threes is 5/1296

4 Threes is 1/1296

the total out come = 6* 6* 6* 6 =1296

Find the probabilities of getting

O Threes =(5/6)^4 = 0.48

1 Three = 1/6*(5/6)^3 = 0.095

2 Threes = 1/6* 1/6* 5/6 *5/6 =0.019

3 Threes = 1/6* 1/6* 1/6 *5/6 = 5/1296

4 Threes =(1/6 )^4 =1/1296

Answer:

y = -1/4x - 2

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

To solve for b, use x = 0:

y = m(0) + b

y = b

y = -2, so b = -2

To solve for m, remember that slope is Δy/Δx.

m = Δy/Δx

Given the two points, (0, -2) and (4, -3), we input them to find the slope:

m = [-3 - (-2)]/(4 - 0)

m = -1/4

Therefore, y = -1/4x - 2.

I'm not quite sure if i'm wrong i'm terribly sorry :(

Answer:

2 - 2 cos²x = sin x

2 = sin x + 2 cos² x

0 = -2 + sin x + 2(1 - sin² x)

0 = -2 sin² x + sin x + 2 - 2

0 = 2 sin² x - sin x 0 = sin x (2 sin x - 1)

sin x = 0 v sin x = 0.5

x10° + k.360° x1 = 0°, 360°

x2 = (180° - 0°) + k.360°

x2 = 180°

x3 = 30° + k.360°

x3 = 30°

x4 = (180° -30°) + k.360° x4 = 150°
