Answer:
Yes
Step-by-step explanation:
the function that gives the alcohol level is:
where x is the number of hours.
we need to know if after 4 hours an average person is legally drunk, thus:
and we substitute this in the function:
solving these operations we obtain:
the alcohol level after 4 hours is 3.24.
Since a person is considered to be legally drunk if the level exceeds 1.5, and we obtained 3.24 which is greater than 1.5, a person who has been drinking for 4 hours under the conditions indicated by the problem would be considered legally drunk.
The answer is 5.13 in²
Step 1. Calculate the diameter of the circle (d).
Step 2. Calculate the radius of the circle (r).
Step 3. Calculate the area of the circle (A1).
Step 4. Calculate the area of the square (A2).
Step 5. Calculate the difference between two areas (A1 - A2) and divide it by 4 (because there are total 4 segments) to get <span>the area of one segment formed by a square with sides of 6" inscribed in a circle.

Step 1:
The diameter (d) of the circle is actually the diagonal (D) of the square inscribed in the circle. The diagonal (D) of the square with side a is:
D = a√2 (ratio of 1:1:√2 means side a : side a : diagonal D = 1 : 1 : √2)
If a = 6 in, then D = 6√2 in.
d = D = 6√2 in
Step 2.
The radius (r) of the circle is half of its diameter (d):
r = d/2 = 6√2 / 2 = 3√2 in
Step 3.
The area of the circle (A1) is:
A = π * r²
A = 3.14 * (3√2)² = 3.14 * 3² * (√2)² = 3.14 * 9 * 2 = 56.52 in²
Step 4.
The area of the square (A2) is:
A2 = a²
A2 = 6² = 36 in²
Step 5:
(A1 - A2)/4 = (56.52 - 36)/4 = 20.52/4 = 5.13 in²
Answer:
4
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)
Since you are subtracting 11 on the side with the variable, you have to add it on the other side. 17+11=28. Then, to solve the problem you are left with, 7c=28. You are multiplying on the side of the variable, so you divide 28 by 7. Your answer to the problem is C=4 i hope this helps
QUESTION 10:
- The long edge of the paper is 11 inches long
- The frame is 4 long edges long
4 times 11 = 44 inches.
Now for the feet calculation!
- 1 foot = 12 inches
44 inches divided by 12 inches is 3 2/3 feet.
RESULT:
Cameron's poster frame is 44 inches long and 3 2/3 feet (OR 3.66666667 feet).
QUESTION 11:
- First, convert 3 yards into feet.
- 1 yard = 3 feet
- 3 yards = 9 feet
- 9 feet plus 2 feet = 11 feet.
- Converting feet into inches means multiplying the number of feet by 12 (since every foot has 12 inches)
-11 feet times 12 = 132 inches.
RESULT:
Use my explanation to determine that 3 yards and 2 feet = 132 inches.
