Find the volume of the sphere. Round your answer to the nearest tenth.
Answers
Answer:
17157.28
Step-by-step explanation:
If we know that the volume of a sphere is equal to V=4/3πr3, then we can assume this.
The radius of the sphere is 16, so 16 cubed is 4096. 4096 x pi is 12867.96
12867.96 x 4/3 is 17157.28
PLEASE ANSWER A AND B, GIVING BRAINLIEST!
Answers
Answer:
a) V = (8 -4/3π)r³
b) 2048(2 -π/3) cm³ ≈ 1951.34 cm³
Step-by-step explanation:
When a sphere is placed in a box the empty space volume is the difference between the box volume and the sphere volume. Here, the box is a cube with the same outside dimensions as the sphere.
__
a. (formula)The side length of the cube is 2r, where r is the radius of the sphere. So, the volume of the cube is ...
V = s³ = (2r)³ = 8r³
The volume of the sphere is given by the formula ...
V = 4/3πr³
The volume of the empty space is the difference of these:
V = (8r³) -(4/3πr³)
V = (8 -4/3π)r³ . . . . . . . formula for the empty volume
__
b. (empty space)For r=8 cm, the empty volume is ...
V = (8 -4/3π)(8 cm)³ = 4(2 -π/3)(512 cm³)
V = 2048(2 -π/3) cm³ ≈ 1951.34 cm³ . . . . empty volume
A farmer has both sheep and chickens on his farm. All the animals have the expected number of parts. When his animals are all
together, there are 90 legs and 32 heads. How many of each animal does he have?
Answers
Answer:
13 sheep, 19 chicken
Step-by-step explanation:
You can start to solve this problem by assigning variables. First, let's assign the number of sheep there are as [tex]x[/tex] and the number of chickens there are as [tex]y[/tex].
Because each sheep has 4 legs, the number of legs for each sheep would be [tex]4x[/tex]. Similarly, because each chicken has 2 legs, the number of legs for each chicken would be [tex]2y[/tex]. Each animal would have 1 head, so the number of heads would just be [tex]x[/tex] and [tex]y[/tex]. Because the number of legs in total are 90, [tex]4x + 2y=90[/tex]. Because the number of heads in total are 32, [tex]x+y=32.[/tex]
There is now a system of equations with two unknown variables and two equations. There are many ways to solve this, but for me, the easiest would be elimination. First, I would double the second equation, [tex]2x+2y=64[/tex]. Then, I would subtract that from the first equation, eliminating [tex]y[/tex]. [tex]2x=26[/tex]. Solving for x gives 13. We can then plug that value into the second equation, making y be [tex]32-13=19[/tex]. This means that [tex]x=13[/tex] and [tex]y=19[/tex], meaning that there are 13 sheep and 19 chicken.

(4.14), because the point lies between the two axes
Answers
Answer:
(3, 11), because both lines pass through this point
Step-by-step explanation:
x = y - 8
y = 3(y -8) + 2
y = 3y - 24 + 2
y - 3y = -22

Write an equation of the line that passes through (2, -5) and has a slope of 4
Answers
Step-by-step explanation:
(y-(-5))/(x-2) = 4
(y+5)/(x-2) = 4
y+5 = 4x - 8
y = 4x - 13
Coordinates are (2,-5) so x = 2, and y = -5. Since the slope is 4, m = 4
Plugging them in, we get:
-5 = 2(4) + b
-5 = 8 + b
-13 = b
The y intercept is -13. So the equation is:
y = 4x - 13.

Identify the geometric mean of 8 and 20 in simplest radical form.
Answers
Answer:

x^2=160
x=sqrt(160)
x=sqrt(16*10)
x=sqrt(16)*sqrt(10)
x=4*sqrt(10)
Step-by-step explanation:
The geometric mean of 8 and 20 in the simplest radical form is 2√10.
What is geometric mean?The Geometric Mean is a unique kind of average in which the numbers are multiplied together and then their square, cube, or other root is taken (for two numbers, three numbers, etc.).
To calculate the geometric mean of two numbers:
You would multiply the numbers together and take the square root of the result.
First, multiply 8 and 20.
That equals 160.
Then you take the square root of 160;
√160
= 12.65,
which doesn't result in a whole number.
So you factor 160 and removing perfect squares.
√160
= √ (4 x 10)
= 2√(10)
Therefore, the geometric mean is 2√10.

8) Choose the correct linear system of inequalities for the graph given.
Answers
Answer:
To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line.
If the inequality is strict ( < or > ), graph a dashed line. If the inequality is not strict ( ≤ or ≥ ), graph a solid line.
Finally, pick one point that is not on either line ( (0,0) is usually the easiest) and decide whether these coordinates satisfy the inequality or not. If they do, shade the half-plane containing that point. If they don't, shade the other half-plane.
Graph each of the inequalities in the system in a similar way. The solution of the system of inequalities is the intersection region of all the solutions in the system.
Example 1:
Solve the system of inequalities by graphing:
y≤x−2y>−3x+5
First, graph the inequality y≤x−2 . The related equation is y=x−2 .
Since the inequality is ≤ , not a strict one, the border line is solid.
Graph the straight line.
Consider a point that is not on the line - say, (0,0) - and substitute in the inequality y≤x−2 .
0≤0−20≤−2
This is false. So, the solution does not contain the point (0,0) . Shade the lower half of the line.
Similarly, draw a dashed line for the related equation of the second inequality y>−3x+5 which has a strict inequality. The point (0,0) does not satisfy the inequality, so shade the half that does not contain the point (0,0) .
The solution of the system of inequalities is the intersection region of the solutions of the two inequalities.
Example 2:
Solve the system of inequalities by graphing:
2x+3y≥128x−4y>1x<4
Rewrite the first two inequalities with y alone on one side.
3y≥−2x+12y≥−23x+4−4y>−8x+1y<2x−14
Now, graph the inequality y≥−23x+4 . The related equation is y=−23x+4 .
Since the inequality is ≥ , not a strict one, the border line is solid.
Graph the straight line.
Consider a point that is not on the line - say, (0,0) - and substitute in the inequality.
0≥−23(0)+40≥4
This is false. So, the solution does not contain the point (0,0) . Shade upper half of the line.
Similarly, draw a dashed line of related equation of the second inequality y<2x−14 which has a strict inequality. The point (0,0) does not satisfy the inequality, so shade the half that does not contain the point (0,0) .
Draw a dashed vertical line x=4 which is the related equation of the third inequality.
Here point (0,0) satisfies the inequality, so shade the half that contains the point.
The solution of the system of inequalities is the intersection region of the solutions of the three inequalities.

In a deck of playing cards, what is the
probability of drawing a red card, replacing it, and
then drawing a queen?
Answers
Step-by-step explanation:
As the cards are being drawn with replacement, the events are independent. Thus we can find the probability by multiplying the probability of individual events.
There are 4 queens in a pack of 52 cards. So, probability of drawing a queen= 4/52=1/13
There are 26 red cards. So, probability of drawing a red card= 26/52=12
Required probability= 1/13×1/2=1/26
Answer:
1/26
Step-by-step explanation:
For probability, the numerator is the number of options for the specified property (red card/drawing a queen) and the denominator is the total number of options (in this case 52).
There are 26 red cards in a deck, the the probability of choosing a red card is [tex]\frac{26}{52}[/tex] or [tex]\frac{1}{2}[/tex].
There are 4 queens in a deck, so the probability of choosing a queen is [tex]\frac{4}{52}[/tex] or [tex]\frac{1}{13}[/tex].
To find the probability of getting these both, multiply the results, giving [tex]\frac{1}{26}[/tex].

A. The quesadillas cost $3.11 each, and the tacos cost $1.69 each.
B. The quesadillas cost $1.57 each, and the tacos cost $3.45 each.
C. The quesadillas cost $3.39 each, and the tacos cost $1.69 each.
D. The quesadillas cost $3.39 each, and the tacos cost $1.57 each.
Answers
C
Explanation:
You could solve this in the elimination way that I have been done in here.
I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.
-> Cross B answer
Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.
Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C
1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.
Which it proves for the answer is C
