Answer:

Part A: $0.25

Part B: They represent the pounds in cabbage and price in dollars

Step-by-step explanation:

Since pounds of cabbage=x and price in dollars=y then this should be helpful 5=x and 2=y so the price of a 5lbs cabbage is 2 dollars since the (5,2) is in (x,y) then it should be simple.

Part A Explanation:

Since 5lbs of cabbage is $2 then I would suggest you divide 5lbs by $2 which is 00.5/2.00=.25 which I'm guessing that 1 pound of cabbage is $0.25

Part B Explanation:

10=x and 4=y so 10= pounds of cabbage and 4= price in dollars, then the ordered pair (10,4) represent the pounds of cabbage and the price in dollars

Hope this is the right way, sorry if it's not, this is the way I pictured it, hope this helps anyone.

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

DENIUS [597]

The answer is 15 in³.

The volume of the cone is:
$V_1= \pi r_1 ^{2} \frac{h_1}{3} = \frac{ \pi r_1^{2} h_1}{3}$
where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone

The volume of the cylinder is:
$V_2= \pi r_2h_2^{2}$
where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone

Since <span>the cone fits exactly inside of the cylinder, they have the same radius and the height:
r</span>₁ = r₂
h₁ = h₂

Also:
V₁ = 5

Now, let's write two volume formulas together:
$V_1= \frac{ \pi r^{2} h}{3}$
<span> $V_2= \pi rh^{2}$ </span>

We can include V₂ into V₁:
$V_1= \frac{V_2}{3}$

⇒ $V_2=3*V_1$
$V_2=3*5 in^{3}$
$V_2=15 in^{3}$

At Friday's football game, 1,294 tickets were sold for a total amount of $8,816.00. If each student ticket costs $5.00, and each

NeTakaya

Answer:

512 student tickets.

Step-by-step explanation:

Let x be number of student tickets and y be number of adult tickets.

We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:

$x+y=1294...(1)$

We are also told that each student ticket costs $5.00, and each adult ticket costs $8.00 and 1,294 tickets were sold for a total amount of $8,816. We can represent this information as:

$5x+8y=8,816...(2)$
