If the length is 9 centimeters then the width should be 4 centimeters. 9cm×4cm=36cm. 36cm is Area. 9cm is your length. Then 4cm must be width.

Alexis, Becca, and Cindy do volunteer work at Adopt-a-Pet Animal Shelter. They worked a total of 285 hours at the shelter last s

swat32

Alexis worked for 59 hours, Becca worked for 74 hours and Cindy worked for 152 hours.

Step-by-step explanation:

Given,

Total hours worked by three of them = 285 hours

Let,

x represent the hours of Alexis.

y represent the hours of Becca.

z represent the hours of Cindy.

According to given statement;

x+y+z=285 Eqn 1

Alexis worked 15 hours less than Becca.

x = y-15 Eqn 2

z = 2y+4 Eqn 3

Putting value of x and z from Eqn 2 and 3 in Eqn 1

$(y-15)+y+(2y+4)=285\\y-15+y+2y+4=285\\4y-11=285\\4y=285+11\\4y=296$

Dividing both sides by 4

$\frac{4y}{4}=\frac{296}{4}\\y=74$

Putting y=74 in Eqn 2

$x=74-15\\x=59$

Putting y=74 in Eqn 3

$z=2(74)+4\\z=148+4\\z=152$

Alexis worked for 59 hours, Becca worked for 74 hours and Cindy worked for 152 hours.

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
