Answer:

150.72 cubic centimeter

Step-by-step explanation:

Given:-

Height of cone (h) = 9cm

Diameter of cone(d)=8cm

radius of cone(r)= $\frac{d}{2}$ = $\frac{8}{2} =4cm$

To calculate= Volume of cone( $V_{cone}$ )

$Volume\ of\ cone(V_{cone}) =\frac{1}{3} \times \pi \times r^{2} \times h$

$=\frac{1}{3} \times 3.14\times 4^{2} \times 9$

Volume of cone( $V_{cone}$ ) $=150.72\ cubic\ centimeter$

Therefore paper cone cup can hold 150.72 cubic centimeter of water.

A movie theater is 10 blocks north and 5 blocks east of a post office. A mall is 7 blocks north and 9 blocks east of the post of

MAXImum [283]

The complete question required that we determine how far is the movie theater to the mall.

<h3>Distance between the movie theatre and the mall </h3>

According to the question;

Upon representation of the movie theatre and mall position on the coordinate plane relative to the post office; we have;

Movie theater, T = (5, 10)
Mall, M = (9, 7).

The distance between the two points can therefore be evaluated by Pythagoras theorem as follows;

Distance, D² = (9-5)² + (7-10)²

D² = 4² + (-3)²

D² = 16 + 9

D² = 25

D = √25 = 5 blocks.

Ultimately, the movie theater is 5 blocks away from the mall.

Simplify each expression. Then state the coefficient of the variable in each expression. 1. U + u + u + u

Pani-rosa [81]

Answer:

4u
the coefficient is 4

Step-by-step explanation:

Using the distributive property, we can write the expression as ...

(1 + 1 + 1 + 1)u = 4u

The coefficient of the variable is 4 in the simplified expression.

If you cut away a triangle of area 59 cm² from a square, the remaining area will be 85 cm². Find the length of the side of the s

siniylev [52]

So the square was fine, then the triangle decided to go for a hike.

now, if the triangle when it took off, it took 59 cm², and the square was left all by its lonesome with only 85 cm², that means with the triangle in it, the square is then 59 + 85 cm², or 144 cm².

$\bf \textit{area of a square}\\\\
A=s^2\qquad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
A=144
\end{cases}\implies 144=s^2
\\\\\\
\sqrt{144}=s
\implies 12=s$

X+6y=27<br> 7x-3y=9 por metodo de igualacion

GalinKa [24]

Answer:

(3,4)

Step-by-step explanation:

The system of equations is:

x+6y=27

7x-3y=9.

I looked up "metodo de igualacion". It is basically American for doing substitution.

However, the only difference is you are asked to solve both equations for a variable.

The first equation looks easy to solve for x. So I'm going to solve both equations for x.

x+6y=27

Subtract 6y on both sides:

x =-6y+27

7x-3y=9

Add 3y on both sides:

7x =3y+9

Divide both sides by 7:

x =3/7 y +9/7

So both equations are solved for x. You want to find when the x's are the same because you are looking for a common amongst the lines given.

So we have

-6y+27=3/7 y +9/7

I hate the fractions honestly so I'm going to multiply both sides by 7 so they will no longer be for now:

-42y+189=3y + 9

Now add 42y on both sides:

189=45y+9

Subtract 9 on both sides:

180=45y

Divide both sides by 45:

4=y

If 4=y, then y=4.

So now once we have obtain 4 for y, we will use one of the equations given along with it to find x. Just choose one. Choose the easier looking one to you.

I like the x=-6y+27 with y=4.

So replace y with giving you:

x=-6(4)+27

x=-24+27

x=3

So the solution is (x,y)=(3,4).

x=3 and y=4.
