Answer:

5.25 miles

Step-by-step explanation:

Answer:

Part A : [tex]1621\frac{1}{3}\pi[/tex] cubic meters.

Part B : 540π cubic cm.

Part C : [tex]V = \frac{4}{3}\pi r^{3}[/tex]

Step-by-step explanation:

Part A :

The volume of the silo includes the volume of a hemisphere and a cylinder.

So, the total volume

[tex]V = \frac{2}{3}\pi r^{3} + \pi r^{2}h[/tex]

⇒ [tex]V = \frac{2}{3} \times \pi (8)^{3} + \pi (8)^{2} (20)[/tex]

⇒ [tex]V = \frac{1024}{3}\pi + 1280\pi = 1621\frac{1}{3}\pi[/tex] cubic meters. (Answer)

Part B :

The volume of the cylindrical cup with height 15 cm and base radius 6 cm is given by

[tex]V = \pi r^{2}h = \pi (6)^{2} (15) = 540\pi[/tex] cubic cm.

Therefore, Mary can put 540π cubic cm of water in the cup with out it overflowing. (Answer)

Part C :

A basketball is of a spherical shape.

So, the formula of its volume is given by [tex]V = \frac{4}{3}\pi r^{3}[/tex]. (Answer)

Answer:

27

Step-by-step explanation:

Answer:27

Step-by-step explanation: 9 goes into 2 zero times. Put a zero on top. 9 goes into 24 two times. Put a 2 on top. Now multiply 9 by 2 and get 18. Put 18 under the 24 and subtract. This gives 6. Bring down the 3 and have 9 into 63 which is 7. Put a 7 on top. The top is the answer of 027, cancel the zero and get 27.

What will be the population after 5 years is 20,683.

Using this formula

A=P(1+r/100)^n

Where:

P=17000

r=4%

n=5 years

Let plug in the formula

P=17,000(1+0.04)^5

P=17,000×(1.04)^5

P=17,000×1.2166529

P=20,683

Inconclusion the population after 5 years is 20,683.

Answer:

the answer is the first graph

Step-by-step explanation:

because the negative points are not viable

The graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a linear equation in the form of slope:

y = 5.5x

Slope of the line m = 5.5

Slope is positive, which means the line goes down to up.

We can plot the graph of the equation y = 5.5x

Option first On a coordinate plane, x-axis is numbered negative 5 to positive 5 in increments of 1, and the y-axis is numbered negative 27.5 to 27.5 in increments of 5.5. A straight line with a positive slope begins at point (0, 0) and ends at point (5, 27.5) is correct.

Thus, the graph of the equation y = 5.5x is shown in the picture and the slope of the line is positive, which is 5.5 option first is correct.

Answer:

y = -9x + 12

Step-by-step explanation:

first find the slope

m= 3 - 12

1 - 0

m = -9

y = mx + b

y = -9x + 12

(the 12 is the y intercept and is given in the question so there is no need to solve for it)

Answer:

None of the above

Step-by-step explanation:

So in order to do this you have to plug in each answer to the equation.

Lets start with (6,0)

0 = -2(6) + 6 =     0 = -6.  This answer is wrong because its false. 0 does not equal -6.

Next answer, (1,4)

1 = -2(4) + 6 =     1 = -2   This answer is also wrong because 1 does not equal -2.

Next answer, (-2,-2)

-2 = -2(-2) + 6 =      -2 = 10   This answer is wrong as well because -2 doesn't equal 10.

This leaves us with none of the above which is true since the first 3 answers are wrong.

Final answer:

To find the value of x, set the expressions equal to each other and solve for x.

Explanation:

To find the value of x in the given equation, we need to set the two expressions equal to each other and solve for x. So, we have:

19x - 36 = 6x + 31

Subtracting 6x from both sides, we get:

13x - 36 = 31

Adding 36 to both sides, we get:

13x = 67

Dividing both sides by 13, we get:

x = 67/13

So the value of x is approximately 5.15.

The only solution to the inequality is point A, (1,4). Thus, the correct answer is A. To find the solution to the inequality [tex]\( y > \frac{1}{2}x + 2\),[/tex] we need to determine which of the given points satisfy the inequality. Let's test each point by substituting its coordinates into the inequality and checking if it holds true.

A. (1,4):

When [tex]\(x = 1\)[/tex] and [tex]\(y = 4\),[/tex] we have:

[tex]\(4 > \frac{1}{2}(1) + 2\)[/tex]

[tex]\(4 > \frac{1}{2} + 2\)[/tex]

[tex]\(4 > 2.5\)[/tex]

This is true, so point (1,4) satisfies the inequality.

B. (-1,1):

When [tex]\(x = -1\)[/tex] and [tex]\(y = 1\)[/tex], we have:

[tex]\(1 > \frac{1}{2}(-1) + 2\)[/tex]

[tex]\(1 > -\frac{1}{2} + 2\)[/tex]

[tex]\(1 > 1.5\)[/tex]

This is false, so point (-1,1) does not satisfy the inequality.

C. (2,3):

When [tex]\(x = 2\)[/tex] and [tex]\(y = 3\)[/tex], we have:

[tex]\(3 > \frac{1}{2}(2) + 2\)[/tex]

[tex]\(3 > 1 + 2\)[/tex]

[tex]\(3 > 3\)[/tex]

This is false, so point (2,3) does not satisfy the inequality.

D. (0,2):

When [tex]\(x = 0\)[/tex] and [tex]\(y = 2\)[/tex], we have:

[tex]\(2 > \frac{1}{2}(0) + 2\)[/tex]

[tex]\(2 > 2\)[/tex]

This is false, so point (0,2) does not satisfy the inequality.

Therefore, the only solution to the inequality is point A, (1,4). Thus, the correct answer is A.

The complete question is:

Which of the following is a solution to this inequality? y>1/2x+2

A. (1,4)

B. (-1,1)

C. (2,3)

D. (0,2)

Step-by-step explanation:

We have,

[tex]-16(0.47)^2[/tex]

To find, the value of [tex]-16(0.47)^2[/tex] = ?

∴ [tex]-16(0.47)^2[/tex]

= [tex]-16(\dfrac{47}{100} )^2[/tex]

= [tex]-16\times \dfrac{47}{100}\times \dfrac{47}{100}[/tex]

= [tex]-4\times \dfrac{47}{25}\times \dfrac{47}{100}[/tex]

= [tex]- \dfrac{47}{25}\times \dfrac{47}{25}[/tex]

=[tex]- \dfrac{2209}{625}[/tex]

= - 3.5344

∴ The value of [tex]-16(0.47)^2[/tex] = - 3.5344

Thus, the value of [tex]-16(0.47)^2[/tex] is equal to - 3.5344.

Answer: [tex]y=0[/tex]

Step-by-step explanation:

For this exercise it is important to remember:

1. The Product of powers property. This property states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

2. The multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then, given:

[tex]8^3*8^{-5}*8^y=8^{-2}=\frac{1}{8^2}[/tex]

You can identify that [tex]8^{-2}[/tex] is obtained by applying the Product of powers property:

[tex]8^{3+(-5)+y}=8^{-2}=\frac{1}{8^2}[/tex]

Based on the explained above, you can write the following equation:

[tex]3+(-5)+y=-2[/tex]

Therefore you must solve for the variable "y" in order to find its value. You get that this is:

[tex]3-5+y=-2\\\\-2+y=-2\\\\y=-2+2\\\\y=0[/tex]

Answer:

You're trying to find the value of y that would result in 8^-2. When you multiply terms with the same base, you can add the exponents. 3+-5=-2 and -2-(-2) equals 0, so therefore y is equal to 0.
