Answer:
P = 30
A = 22
Step-by-step explanation:
Find perimeter first
P = 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 + 4 + 4
P = 10 + 12 + 8
P = 30
Now area
A = 2(5 * 2) + (2 * 1)
A = 2(10) + (2)
A = 20 + 2
A = 22
Answer:81
Step-by-step explanation:
9•9 = 81
If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level.
Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic, a pH above 7 is basic, or alkaline. Seawater has a pH just more than 8, whereas lemonade has a pH of approximately 3.
Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.
The pool maintenance man forgot to bring his logarithmic charts, and he needs to raise the amount of hydronium ions, t, in the pool by 0.50. To do this, he can use the graph you created. Use your graph to find the pH level if the amount of hydronium ions is raised to 0.50. Then, convert the logarithmic function into an exponential function using y for the pH.
The pool company developed new chemicals that transform the pH scale. Graph the parent pH function p(t) = −log10t and the transformations below on the same graph. Send the graph to your partner. Your partner will explain which transformation results in a y-intercept and why. You may graph by hand or using technology. Use complete sentences.
p(t) + 1
p(t + 1)
−1 • p(t)

p(t)=-log(t)
p(.5)=-log(.5)= 0.3
y=-log ^(0.5)
10^-y= 0.5
10
p(t)+1
Red line on graph, this transformation has shifted up by 1. This translation doesn't result in a y-intercept.
p(t+1)
Blue line on graph, this transformation is shifting to the left by 1. This translation results in a y-intercept because it crosses the y-axis.

Answer:
Kenny has eaten <u>44 ice cream scoops</u>.
Step-by-step explanation:
Given:
Kenny uses 
of the chocolate syrup bottle for every scoop of ice cream that he eats.
Now, to find the scoops of ice cream Kenny has eaten, If he has used 
bottles of chocolate syrup.
So, we use unitary method to find the number of scoops of ice cream:
<em>If, </em><em> of the chocolate syrup bottle Kenny uses to eat = </em>
<em />
<em>Then, 1 of the chocolate syrup bottle Kenny uses to eat </em>
<em />
<em>Thus, </em><em> bottles of chocolate syrup bottle Kenny uses to eat</em> = 
Therefore, Kenny has eaten 44 ice cream scoops.
I believe the answer is the second option.
