A flour canister is 25 cm tall and has a diameter of 20 cm. It is filled to 3 cm from top. what volume of flour does it contain?

1 answer:

6 0

Volume of a cylinder= πr²h.
So pi always =3.14.
The radius is half the diameter: 20/2=10.
The height is the height of the flour in the canister: 25-3=22.

So V=3.14(10²)(22).
V=3.14(100)(22).
V=314(22).
V=6,908 cm³ :)

For the inverse variation equation P=8/V, what is the value of V when P = 1/2?

postnew [5]

P = 8/v
1/2 = 8/v
multiply v on both sides
1/2 v = 8
multiply 2/1 on both sides (the reciprocal of (1/2)
v = 16
Letter D

Use the graph to write an explicit function to represent the data and determine how much money Amy earned in week 5.

Answer:

3rd option

$f(n)=5(3)^{n-1}$

$f(5)=405$

Step-by-step explanation:

So we are given the following points:

(1,5)

(2,15)

(3,45)

(4,135)

This is a geometric sequence because there is a common ratio, 3. That is you can keep multiply 3 to a previous y-coordinate to get the next y-coordinate.

The formula for a geometric sequence is $f(n)=a_1 \cdot r^{n-1}$

where $a_1$ is the first term and r is the common ration.

So we have

$f(n)=5 \cdot (3)^{n-1}$ .

If you want to know the fifth term, just plug in 5:

$f(5)=5 \cdot (3)^{5-1}$

Simplifying:

$f(5)=5 \cdot 3^4$

$f(5)=5 \cdot 81$

$f(5)=405$

June made a design with 6 equal tiles.One tile is yellow 2 tiles are blue and 3 tiles are purple. what fraction of the tiles are

lana66690 [7]

we know that

The fraction of each tile color can be found by dividing the number of tiles for each tile by the total number of tiles, then simplifying the fraction if possible.

Let

N----------> total number of tiles

Y---------> number of yellow tiles

B--------> number of blue tiles

P--------> number of purple tiles

we have

$N=6\\ Y=1\\ B=2\\ P=3$

1) Find the fraction of yellow tiles

we know that

the fraction of yellow tiles is equal to

$Y/N$

substitute the values

$1/6$

2) Find the fraction of purple tiles

we know that

the fraction of purple tiles is equal to

$P/N$

substitute the values

$3/6$

3) Find the fraction of yellow tiles or purple tiles

we know that

the fraction of yellow tiles or purple tiles is equal to

$(Y/N)+(P/N)=(1/6)+(3/6)=4/6=2/3$

therefore

the answer is

$2/3$

25xy=225 convert to polar form

bixtya [17]

$\bf x=rcos(\theta)\qquad \qquad y=rsin(\theta)\\\\
-----------------------------\\\\
25xy=225\implies xy=\cfrac{225}{25}\implies xy=9
\\\\\\
rcos(\theta)\cdot rsin(\theta)=9\impliedby \textit{common factor}
\\\\\\
r[cos(\theta)sin(\theta)]=9\implies r=\cfrac{9}{cos(\theta)sin(\theta)}$

All side lengths of ΔJKL equal 2 units. A transformation maps ΔJKL to ΔJ'K'L'. The length of side J'K' is 5 units. Is this a rig

S_A_V [24]

No because at least one segment length is not preserved.
rigid means everything stays the same, but orientation sometimes changes.
