Find the volume of a right circular cone that has a height of 3.9 ft and a base with a circumference of 16.3 ft. Round your answer to the nearest tenth of a cubic foot.

Answer:

-1

Step-by-step explanation:

This question is based on the concept of equation of line.Therefore, the slope of the given graph is -1 and the y - intercept of the graph is  ( 0, 0.25).

Given:

Graph y = -x + 0.25

We need to determined the slope and y-intercept of the graph.

According to the question,

As we know that, the equation of line is y = m x +c,

Where, m = slope and c = y - intercept.

Now compare the given graph equation y = -x + 0.25 is with  y = mx +c.

We get,

Slope = -1

And, y - intercept = ( 0, 0.25)

Therefore, the slope of the given graph is -1 and the y - intercept of the graph is  ( 0, 0.25).

Number of Inches there are in 7 yards is 252inches

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

Given;

3feet= 1yard

12inch= 1foot

So,

1foot= 12inch

3feet= 12 x 3inch

        = 36inch...(1)

1yard= 3feet

7yard= 7 x 3 x 1foot

        = 21 x 1foot

Substituting the value of 1foot from equation 1

 7yard= 21 x 12inch

7yard= 252inches

Therefore, the answer of this conversion will be 252inches

Answer:

Trevor read 157.5 pages this week.

Step-by-step explanation:

Simple multiplication.

Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17.  The first line should be 175.

Put a 0 on the last digit to solve for the next digit.  Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14.  The second line should be 1400.

Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.

x=1, y=2

Step-by-step explanation:

solve by substitution so substitute x= 6y-11 in the next equation

3 (6y-11) - 2y = -1

18y -33-2y = -1

16y = 33-1

y= 32/16 =2

Hi

first thing to do is to count how many marbles you have

so :  5 red, 4 green, 3 blue  =  5+4+3 = 12  

probability  of  green :    4/12

                         blue   :     3/12  

Probability of  either  green or blue  :  4/12 +3/12 = 7/12  

The probability that it is either a green marble or a blue marble is : P(A or B) = 7/12.

Given is that an urn contains five red marbles, four green marbles, and three blue marbles

We can write that the probability that it is either a green marble or a blue marble is -

P(A or B) = P(A) + P(B)

P(A or B) = (4/12) + (3/12)

P(A or B) = 1/3 + 1/4

P(A or B) = (4 + 3)/12

P(A or B) = 7/12

Therefore, the probability that it is either a green marble or a blue marble is : P(A or B) = 7/12.

Answer:

I think its C

Step-by-step explanation:

-x + y > 2 you need to isolate y on one side and to do that u add x on both sides then you get y > x + 2. the +2 is the y-intercept and the x (or 1x) is the slope. since y is bigger than x + 2 then the graph should cover everything above the slope 1x.

and since its not a [tex]\geq[/tex] it only covers numbers above that. otherwise it would be a solid line instead of a dotted one

Answer:

27 years

Step-by-step explanation:

Given that :

Town A:

Initial population = 14280

Rate = increase by 160 per year

Let t = time in years

Population is thus :

14280 + 160t - - - (1)

Town B:

Initial population = 24000

Rate = decrease by 200 per year

P = 24000 - 200t - - - (2)

Equate both equations :

14280 + 160t = 24000 - 200t

160t + 200t = 24000 - 14280

360t = 9720

t = 9720 / 360

t = 27

Percent error = [tex]\dfrac{|\text{ Estimated value - actual value}|}{\text{actual value}}\times100\\[/tex]

Actual value = 1372 g/L

Percent error = [tex]\dfrac{|1360-1372|}{1372}\times100\\\\[/tex]

Answer:

If you mix x quarts of 6% butterfat milk with y quarts of 2% butterfat milk, then the resulting mixture would have a total volume of x + y quarts.

1 quart of the 6% milk contains 0.06 quart of fat, and 1 quart of the 2% contains 0.02 quart of fat. So x quarts of 6% milk contains 0.06x quart and y quarts of 2% milk contains 0.02y quart of fat, and the resulting mixture would contain a total of (0.06x + 0.02y) quarts of fat.

You want to end up with 80 quarts of 5% milk, which contains 0.05 • 80 quarts = 4 quarts of fat, so that

x + y = 80

0.06x + 0.02y = 4

Solve for x and y :

y = 80 - x

0.06x + 0.02 (80 - x) = 4

0.06x + 1.6 - 0.02x = 4

0.04x = 2.4

x = 60

y = 20
