Answer:

Answer: 5/12 or approx. 0.42

Step-by-step explanation:

The ball will displace as much water as its volume.

Meaning, the volume of the ball and the volume of the increase in water in the barrel will be equal.

Volume of a sphere:

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

The radius is half the diameter. The diameter of the sphere is 10, thus:

[tex]r = d/2 = 10/2 = 5[/tex]

5^3 = 5*5*5 = 25*5 = 125

[tex]V_s=\frac{4}{3} \pi * 5^3=\frac{4}{3} \pi * 125[/tex]

The volume of a cylinder, which will be the shape of the increase in water, is the following:

[tex]V_c=\pi r^2 h[/tex]

We know the radius r, as we know the diameter.

[tex]r=d/2=40/2=20[/tex]

[tex]V_c=\pi r^2 h=\pi h * 20^2 = \pi h * 400[/tex]

We are looking for the height of the cylinder, h, as that will be the height of the water rise.

Since we know these 2 volumes are the same, we'll set them equal to each other and solve the equation:

[tex]V_s = V_c[/tex]

[tex]\frac{4}{3} * 125 * \pi = 400 * h * \pi[/tex]

We can get rid of pi by dividing both sides by pi:

[tex]\frac{4}{3} * 125 = 400 * h[/tex]

And now divide both sides by 400:

[tex]\frac{4}{3} * \frac{125}{400}= h[/tex]

Just reversing it and putting h to the left:

[tex]h = \frac{4}{3} * \frac{125}{400} = \frac{4 * 125}{3 * 400}[/tex]

I see that I can divide both the numerator and the denominator by 4:

[tex]h =\frac{125}{3 * 100}= \frac{125}{300}[/tex]

I'll now divide both the numerator and the denominator by 25 to simplify the expression:

[tex]h=\frac{125}{300} =\frac{125 / 25}{300 / 25} = \frac{5}{12}[/tex]

Answer: The water rises by 5/12 (five twelfths).

If I want an approximate decimal answer, I can simply run this expression in a calculator:

[tex]\frac{5}{12}[/tex] ≈ [tex]0.416666667[/tex] ≈ [tex]0.42[/tex]

The amount of water rise is 0.42 and this can be determined by using the formula of the volume of the sphere and the cylinder.

Given :

A stone is dropped into a barrel of water and sinks to the bottom.

The ball is completely covered by water.

The following steps can be used in order to determine the water rise in the barrel:

Step 1 - The formula of the volume of a sphere is used in order to determine the water rise in the barrel.

Step 2 - The volume of a sphere is given below:

[tex]\rm V_s=\dfrac{4}{3}\times \pi \times r^3[/tex]

Step 3 - Substitute the values of the known terms in the above expression.

[tex]\rm V_s=\dfrac{4}{3}\times \pi \times \left(\dfrac{10}{2}\right)^3[/tex]

Step 4 - Simplify the above expression.

[tex]\rm V_s = \dfrac{4}{3}\times \pi \times 125[/tex]   --- (1)

Step 5 - The volume of the cylinder is given below:

[tex]\rm V_c= \pi\times \left(\dfrac{40}{2}\right)^2\times h[/tex]   --- (2)

Step 6 - Equate expression (1) and (2) in order to determine the value of 'h'.

[tex]\dfrac{4}{3}\times \pi \times 125= \pi \times 400 \times h[/tex]

Step 7 - Simplify the above expression.

[tex]\rm h = \dfrac{4\times 125}{3\times 400}[/tex]

h = 0.42

AB+OA= 2CM

Plus means addition and square root means √

3 plus the square root of negative 16: 3 + √-16

Minus means subtraction and square root means √

6 minus the square root of negative 64: 6 - √-64

Its asking you to multiply both quantities.

(3 + √-16) * (6 - √-64)

Best of Luck!

Answer:

18-32i^2

Step-by-step explanation:

3 + the negative square root of 16 would simplify to 4i

so it will be (3+4i)

6 - the negative square root of 64 would simplify into 8i

so it will be (6-8i)

To solve (3+4i)(6-8i) use FOIL and add like terms

Answer:

130 mg

Step-by-step explanation:

As the statement indicates that the daily recommended amount of calcium is 1,000 mg and that Velveeta contains 13% of that, you have to calculate the 13% of 1,000 to find the answer:

1,000*13%=130

According to this, there are 130 mg of calcium in one serving of Velveeta.

The blue and red light will flash together after every 24 seconds.

What is LCM ?

LCM is the Least Common Multiple of at least two numbers, It is the smallest number that will be completely divisible by both the numbers.

The blue light flashes every 8 seconds

The red light flashes every 12 seconds

The time at which they will flash together can be determined by finding their LCM

LCM of 8 and 12 is 24.

Therefore, after every 24 seconds, they will flash together.

Scientific Notation is so useful in many ways

It makes it easier to deal with because the long numbers are converted into smaller numbers. Like for example, 0.000000000000000000000000000000000000000000045 is converted into 4.5*10^44. Isn't that MUCH MORE simpler?!?!??!

It is also used to find masses, for example, like some metals or substances that have a really smaller mass.

Step-by-step explanation:

Answer:

y2 = m(x1 - x2)+ y1

Step-by-step explanation:

m = y2 - y1 / x1 - x2

m(x1 -x2) = y2 -y1

y2 = m(x1 - x2)+ y1

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

Multiply both sides by (x2 - x1)

m(x2 - x1) = y2 - y1

Add y1 to both sides

m(x2 - x1) + y1 = y2

y = m(x2 - x1) + y1
