Answer:

b = 10

Step-by-step explanation:

P = 2 (l + b)

l = 15

P = 50

Substitute

50 = 2 (15 + b)

multiply

50 = 30 + 2b

subtract

20 = 2b

divide

b = 10

<h3><u>G</u><u>i</u><u>v</u><u>e</u><u>n</u>:-</h3>

P = 2 (l + b) when l = 15 and P = 50

<h3><u>T</u><u>o</u><u> </u><u>F</u><u>i</u><u>n</u><u>d</u>:-</h3>

To find b

<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

P = 2 (l + b) [Given]

Putting the value of P = 50 and l = 15 we get,

50 = 2(15 + b)

\frac{50}{2} = 15 + b

25 = 15 + b

25 - 15 = b

10 = b

So, b = 10

<h3>Value of b is <u>1</u><u>0</u>. [Answer]</h3>

Need help with Number 11.Show your work plz.Please answer Quick.
Zanzabum
Jennifer earns $5.50 per hour

Edward earns ($5.50*1.8) $9.90 per hour

Edward earns more per hour

To find out how many hours they'd have to work to make 50$, we would just divide $50 by their hourly wage.

Jennifer=50/5.50=9.09 hours    since you cant have 0.09 hours round up
Jennifer=10 hours to make at least $50 dollars

Edward=50/9.90=5.05 hours    since you cant have 0.05 hours round up
Edward=6 hours to make at least $50 dollars


**Edit. Since Edward earns 1.8 times what Jennifer earns, that means he earns 180% of what she earns or 80% more. So we can tell that he earns more just by the 1.8.

1.8=180%

Compare the wins-to-losses ratios for the teams. Team Records Team Wins Losses Cougars 12 10 Bobcats 20 10 Bulldogs 8 5 Tigers 3
UkoKoshka [18]

Answer:

Bobcats

Step-by-step explanation:

The wins-to-losses ratio for the Cougars is 12:10.  This can also be written as 12/10; writing this as a decimal, we would have 1.2.

The wins-to-losses ratio for the Bobcats is 20:10.  This can also be written as 20/10, which is the same as 2.0.

The wins-to-losses ratio for the Bulldogs is 8:5.  This can also be written as 8/5, which is the same as 1.6.

The wins-to-losses ratio for the Tigers is 3:5.  This can also be written as 3/5,l which is the same as 0.6.

The largest of these decimals is 2.0; this means the Bobcats have the greatest ratio of wins to losses.
