Justin uses 4 right angles to draw a polygon. How many different polygons can he make?

Vitek1552 [10]

He can make an infinite number of different polygons,
as long as each one has more than 3 sides.

If the polygon has four sides, then it's always a parallelogram
and a rectangle, and it might also be a square.

Svet_ta [14]

Answer:

3620.57

Step-by-step explanation:

Given: Stacy hits the jackpot one day at the gumball machine and won 4 gumballs, radius of each gumball is 6 mm

To find: Total volume of all 4 gumballs

Solution:

Gumball is Spherical

Volume of Sphere = (4/3)πr³

r = Radius of Sphere

r = 6mm

Volume of 1 gumball = (4/3)π * 6³

= 288π mm³

Volume of 4 gumballs = 4 * 288π

= 1152π mm³

using π = 22/7

= 3,620.57 mm³

or using π = 3.14

= 3,617.28 mm³

Volume of 4 gumballs = 288π mm³ ≈ 3,620 mm³

Each cone of the hourglass has a height of 18 millimeters . the total height of the sand within the top portion of the hour glas

statuscvo [17]

Let

Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm

then

Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³

the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688

if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X

X=π*2688/10π=268.8 seg

the answer is 268.8 seg

prohojiy [21]

Answer:

<u>212,400 items</u> were sold in 10 months.

Step-by-step explanation:

Given:

Items sold this month = 70,800

Percent Increase in every month = 20%

We need to find number of items sold in coming 10 months.

Solution:

First we will find number of items increase in each month.

number of items increase in each month can be calculated by Percent Increase in every month multiplied by Items sold this month and the divided by 100.

number of items increase in each month = $\frac{20}{100} \times 70800 = 14,160$

Now we will find number of item sold in 10 months.

number of item sold in 10 months is equal to sum of Items sold this month and number of items increase in each month multiplied by 10.

framing in equation form we get;

number of item sold in 10 months = $70800+10\times 14160 = 212,400$

Hence <u>212,400 items</u> were sold in 10 months.
