100 in ^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+ b2) *h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 16+9) * 8
= 1/2 ( 25) *8
= 100 in ^2
1/2*(9+16)*8=100
It normally takes Julius 2 hours to mow the yard, but because he is in a hurry he asks his son, Marcos, to help him. If just his son was doing the yard work it would take him 3 hours. How long will it take if both are working together? Use the formula 1/T_1 +1/T_2 =1/T_both where T_1 is the time required for Julius to complete the job alone, T_2 is the time required for Marcos to complete the job alone, and T_both is the time required to complete the job when they both work together. Answer as a decimal, rounded to one decimal place.
Answers
Answer: 1.2 hours
Step-by-step explanation:
Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]
Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]
Let the time taken by both to complete the job together = T
[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]
[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]
Hence, it will take 1.2 hours to complete the job by working together.

Answers
Answer:
5.319149 oz per dollar
Step-by-step explanation:
This is a fraction equal to
10 oz ÷ 1.88 dollars
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1.88
10 oz ÷ 1.88
1.88 dollars ÷ 1.88
=
5.319149 oz
1 dollar
=
5.319149 oz
dollar
= 5.319149 oz per dollar
I looked up a unit rate calculator and this is what I got because honestly i forgot how to do this but I hope it helps.

Answer: I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
Step-by-step explanation:
The percentage of the body affected by the disease is a function of the number of days:
P(d) = 6d + 5This percentage is a dependent variable and the number of days is the independent variable.
If we give values to d, we can calculate the percentage of the body affected by the disease.
P(1)= 6·1 + 5 = 11%
P(2)= 6·2 + 5 = 17%
P(3)= 6·3 + 5 = 23%
P(4)= 6·4 + 5 = 29%
P(5)= 6·5 + 5 = 35%
P(6)= 6·6 + 5 = 41%
P(7)= 6·7 + 5 = 47%
P(8)= 6·8 + 5 = 53%
Depending on the days since the beginning of the disease, the doctors have a treatment for a different stage.
Starting immediately, the treatment will be stage 1: less than 15%
Starting on day 2 or 3, the treatment will be stage 2: 15-25%
After day 3, the treatment will be stage 3: 25-50%
After day 8, there is no cure: more than 50% of the body is affected by the disease.
I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.

Complete question is;
Write each set in the indicated form.
If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.
As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.
(a) Roster form: {6,8,10,12,...}
Descriptive form:
(b) Descriptive form: The set of natural numbers greater than or equal to 3 and less than or equal to 6.
Roster form:
Answer:
A) Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) Roster form: {3, 4, 5, 6}
Step-by-step explanation:
A) We are given that the roster form is;
{6,8,10,12,...}
Now, the descriptive form is just a statement that describes the given roster form.
Now, we can see they are all even natural numbers and the least is 6 while after 12,we can see that the set continues.
Thus;
Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) We are given that the descriptive form is the set of natural numbers greater than or equal to 3 and less than or equal to 6.
This means the least number in the set is 3 while the highest number is 6.
Thus,the roster form is;
Roster form: {3, 4, 5, 6}
