Answer:

30 cubic feet

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Height of cone (h) = 10 feet

Base surface area = π[tex]r^{2}[/tex] =  9 sq. feet

So we can calculate the volume of cone by using following formula,

volume of cone = (1/3)π[tex]r^{2}[/tex]h

By putting the value in the formula, we get

Volume of cone = (1/3) 9 × 10

= 3 × 10

= 30 cubic feet

Answer:

4374

Step-by-step explanation:

Since, we are given table for x and y values

and table for average rate of changes

we can see the pattern of average rate of change

average rate of change for 5 to 6 is three times average rate of change for 4 to 5

but we have to find

average rate of change for 7 to 8

so, using same pattern

average rate of change for 6 to 7 is three times average rate of change for 5 to 6

average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)

so, we can plug value

average rate of change for 7 to 8 is 3*3*486

average rate of change for 7 to 8 is 4374

Answer:

-1.2

Step-by-step explanation:

3n + 5 = 1/2(11n + 16)

3n + 5 = 5.5n + 8

5 = 2.5n + 8

-3 = 2.5n

-3/2.5 = n

-1.2 = n

Hope this helps!

Answer:

[tex]n=-1.2[/tex]

Step-by-step explanation:

First, solve both sides of the equation:

[tex]3n+5=\frac{1}{2} (11n+16)[/tex]

[tex]3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16)[/tex] (Distribute)

[tex]3n+5=\frac{11}{2} n+8[/tex]

Then, subtract 11/2 n from both sides:

[tex]3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n[/tex]

[tex]\frac{-5}{2}n+5=8[/tex]

Now, subtract 5 from both the sides:

[tex]\frac{-5}{2} +5-5=8-5[/tex]

[tex]\frac{-5}{2} n=3[/tex]

For the last step, multiply both the sides by 2 / -5

[tex](\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)[/tex]

[tex]n=\frac{-6}{5}[/tex]

Convert it to decimal:

[tex]n=-1.2[/tex]

a = 53

Step-by-step explanation:

A bisector creates two equal angles. Set them equal to each other.

5a - 160 = 2a - 1  ( subtract 2a from both sides)

3a = 159               (add 159 to both sides)

a = 53                   (divide by 3)

Step-by-step explanation:

for every pie pua needs 3/4 cups of sugar

you can know this by dividing the sugar by the pies

then you can multiply 12 by 3/4 to find how many cups are needed for 12 pies, which is 9

Answer:

9

Step-by-step explanation:

6 devided by 2 is three

8 divided by two is four

four times three makes the amount of pies you need

since you are making the times the new numbers amount, then you need to multiply the amount of sugar that you just devided by two by three

Given:

Total cheese = 12 pound

Cheese in each package = [tex]\dfrac{1}{2}[/tex] pounds

To find:

The number of cheese packages.

Solution:

We need to divide the total amount of cheese by quantity of cheese in each package to find the the number of cheese packages.

[tex]\text{Number of cheese packages}=\dfrac{\text{Total cheese}}{\text{Cheese in each package}}[/tex]

[tex]\text{Number of cheese packages}=\dfrac{12}{\dfrac{1}{2}}[/tex]

[tex]\text{Number of cheese packages}=12\times \dfrac{2}{1}[/tex]

[tex]\text{Number of cheese packages}=24[/tex]

Therefore, there are 24 number of cheese packages.

Answer:

152

Step-by-step explanation:

All segments in a triangle add to 180. 1

8+10+x=180

x=152

The length x using Pythagoras theorem is 15 unit.

According to the Pythagorean theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the other two sides.

Given:

Hypotenuse = 18 unit

Perpendicular = 10 unit

using Pythagoras theorem

H² = P² + B²

18² = 10² + B²

324 = 100 + B²

324 - 100 = B²

B² = 224

B= 14.966 unit

B= 15 unit

Thus, the measure for x is 15 unit.

Answer:

Step-by-step explanation:

As,

Integers includes whole numbers, and negative of the whole numbers.

And Rationals includes every fraction, Integers and negative fraction.

So,

170, -25, and 74 are both Integers and Rationals.

But,

Only 3/10 is a fraction included only in rationals and not in Integers

Answer:

Step-by-step explanation:

All this question is asking you to do is distribute through the parenthesis to simplify. Doing that gives us

f(n) = 7 - 3n + 3 and

f(n) = 10 - 3n or

f(n) = -3n + 10, choice D.

The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10 thus option (D) is correct.

An arrangement known as a function connects inputs to essentially one output.

The machine may only produce one output for each input and will only accept inputs that are specifically listed as part of the function's domain.

As per the given,

a_n = 7 - 3(n - 1)

f(n) = 7 - 3n + 3

f(n) = -3n + 10

Hence "The representation of the function of the given arithmetic sequence 7 - 3(n - 1) is f(n) = -3n + 10".
