Answer:

312π mm3

Step-by-step explanation: yes

The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct

The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.

Volume is defined as the ratio of the mass of an object to its density.

Volume of composite figure =  Volume of semi-sphere  + Volume of cone
                                              =   2/3πr³ + 1/3πr²h
                                              =  2/3*6³π + 1/3*6²*14π
                                              =   312π mm³

Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Answer:

1728.

Step-by-step explanation:

It is given that The numbers of different plant types are in the ratio  

Tall green:Tall yellow:Short green:Short yellow = 8:5:2:1.

Let the numbers of Tall green, Tall yellow, Short green:, Short yellow are 8x, 5x, 2x, x respectively.

Number of green plants [tex]=8x+2x=10x[/tex]

It is given that there are 1080 green plants.

[tex]10x=1080[/tex]

[tex]x=108[/tex]

Number of total plants [tex]=8x+5x+2x+x=16x[/tex]

[tex]16x=16(108)=1728[/tex]

Therefore, total plants are in Gregor's yard is 1728.

Answer: 12.63 years

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

A = P (1 + r) t  

Where:  

p = original price

r = increasing rate (decimal form)  

t= years  

A = price after t years  

10= 3 (1 + 10/100) t  

10= 3(1.1)^t

10/3= 1.1^t

log 10/3 = log 1.1^t

log 10/3 = t log 1.1

log (10/3)/ log 1.1 =t

t = 12.63 years

Answer:

x=63

Step-by-step explanation:

If f(x)=8 and f(x)=71-x, these can be set equal to eachother

71 - x = 8

Subtract 71 from both sides to isolate the variable

- x = -63

divide both sides by -1 because the variable can not be negative

x = 63

Answer:

The width of the pathway is:

Step-by-step explanation:

To identify the width of the pathway, you must remember the area formula of a rectangle:

From which the width can be cleared:

We know that the length of the terrain was not modified since the pathway is in the perimeter of the rectangle (16 m) and that the new area is 240 m^2, so we only have to replace the cleared formula:

The new width is equal to 15 meters, but since the question is not the total width but the width of the pathway, the width of the previously provided land must be subtracted from the value obtained.

Answer:

9:17 P.M.

Step-by-step explanation:

If the drive is 2 hours and 45 minutes and they need to be there by 12:02 am, you subtract two hours from that number. This means that if the drive was only two hours, they would have to leave home at 10:02 pm. However, it is 45 minutes longer than that so you have to subtract 45 minutes from 10:02 pm which gets 9:17 pm. Hope this helps!

Answer:

why a math problem

Step-by-step explanation:

math is hard

Answer:

slope is 4 and y-intercept is 12

Step-by-step explanation:

To solve this problem, let's actually just write the equation of the line in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Given (-3, 0) and (-2, 4), the slope will be: (4 - 0) / (-2 - (-3)) = 4 / 1 = 4. So, the slope is m = 4.

Now, our equation so far is y = 4x + b. To find b, plug in, say, -3 for x and 0 for y:

0 = 4 * (-3) + b

0 = -12 + b

b = 12

Then the slope is 4 and the y-intercept is 12.

Answer:

[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{0 - 4}{-3+2} = \frac{-4}{-1} = 4[/tex]

4 is the slope

now we have to plug in the slope intercept formula where m is 4

you can find b by plugging one of the points

I choose (-3,0) since it is easier to work with

0 = 4(-3) + b

0 = -12 + b

12 = b

Our y intercept is 12

finally the slope intercept form is

y = 4x + 12

Slope formula - (y2 - y1)/ (x2-x1)

Slope intercept form = y = mx + b

Answer:

(1/3)n  ≤ 12

Step-by-step explanation:

“One-third of a number is at most 12” becomes

      (1/3)n                                 ≤        12, or

(1/3)n  ≤ 12

First find the common ratio of this geometric sequence.

We will use [tex]r = \frac{a2 }{a1 }[/tex].

The second term is 21 and the first term is 7.

So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.

So, we take the last term in our geometric sequence

and multiply it by the common ratio we just found.

So we have 63 · 3 which is 189.

So the next term in this geometric sequence is 189.

Answer:

A

Step-by-step explanation:

The reason it is A is because

It goes in biggest to lowest A B C D

C and B don't follow that so we are left with A and D

In answer D   C and B are too close in percentage therefore it cannot be D

Therefore your answer is A

Answer:

y = x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

y - (- 11) = x - (- 11), that is

y + 11 = x + 11 ( subtract 11 from both sides )

y = x ← in slope- intercept form

Yes.

The additive is what you add to a number to get zero.

The negative of a number.

Example:

The additive inverse of −5 is +5, because −5 + 5 = 0

The additive inverse of +5 is −5, because +5 − 5 = 0

Additive inverses are negated numbers.

The points on the number line are additive inverses.

For a number x, the additive inverse is -x.

The first point on the number line is:

[tex]\mathbf{x = 3}[/tex]

Negate both sides

[tex]\mathbf{-x = -3}[/tex]

-3 represents the additive inverse of 3.

Hence, the points on the number line are additive inverses.

Answer:

It'll be worth approximately $8779.3 after 5 years.

Step-by-step explanation:

Since it's compounded we need to use the appropriate formula to solve this problem, which is shown below:

M = C*(1 + r)^t

Where M is the final amount, r is the interest rate and t is the time elapsed in years. Applying the data from the problem we have:

M = 7500*(1 + 0.032)^5

M = 7500*(1.032)^5

M = 8779.2971

It'll be worth approximately $8779.3 after 5 years.
