The volume for a sphere is 4/3Pi(r^3), or
4/3 • 3.14 (Pi estimated) • (r • r • r).

Pi is 3.14 estimated, and r is the radius (from a curve to the midpoint of a circle).

I hope this helps!

4) During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play
ioda

$225 was earned from the craft sales

and $40 was earned from the play.

Given, During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play admissions.

Of each dollar earned, $0.15 came from games. Craft sales earned 3 times as much as games. Food sales were 4 times the amount earned from the play.

Let the amount earned by play be x,

Now, Games earned = 0.15×500 = $75

Also, crafts earned 3×75 = $225

Now, as play earned x, then food earned 4x.

According to question,

x + 75 + 225 + 4x = 500

5x + 300 = 500

5x = 200

x = 40

So, the amount earned by Play be, $40

and the amount earned by Food be $160.

Hence, $225 was earned from the craft sales

and $40 was earned from the play.

3. PLZZZZ HELP MEEE!.!.!
andre [41]

Answer:

60in²

Step-by-step explanation:

Since lateral surface area means all the shapes except the base, we will ignore the square in the middle.

A=1/2(b*h)

A=1/2(10*3)

A=15in²

Now we will multiply the area by 4 or the number of other shapes besides the base.

60in²

Table:

x      y

-3    0.5

-2    1

-1     2.5

0      5

1      8.5

Now, y = ax^2 + bx + c

Start replacing x = 0 and y = 5

5 = a(0) + b(0) + c => c = 5.

Now, replace any other two pair of data:

(-2, 1) => -1 = a(-2)^2 + b(-2)

-1 = 4a - 2b

(1, 8.5) => 8.5 = a(1)^2 + b(1)

8.5 = a + b

Solve the system

4a - 2b = - 1
a + b = 8.5

=>

4a - 2b = - 1
2a + 2b = 17
-------------------------

6a = 16

=> a = 16 / 6 = 8/3

b = 8.5 - a = 17/2 - 8/3 = 35/6

=> y = (8/3)x^2 + (35/6)x + 5 <--------- answer
