Researchers measured the average blood alcohol concentration C(t) of eight men starting one hour after consumption of 30 mL of ethanol (corresponding to two alcoholic drinks). (Round your answers to two decimal places.) t (hours) 1.0 1.5 2.0 2.5 3.0 C(t) (mg/mL) 0.35 0.26 0.2 0.14 0.09 (a) Find the average change of C with respect to t over each time interval. (i) [1.0, 2.0] (ii) [1.5, 2.0] (iii) [2.0, 2.5] (iv) [2.0, 3.0]
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below:
Time, t (hours)__1.0__1.5__2.0__2.5__3.0
C(t) (mg/mL)__0.35_0.26_0.20_0.14_0.09
Average change of C with respect to t over the interval :
(i) [1.0, 2.0] (ii) [1.5, 2.0] (iii) [2.0, 2.5] (iv) [2.0, 3.0]
Average change = ( change in C / change in t) = C2 - C1 / t2 - t1
1) [1.0, 2.0]
C at t = 1 = 0.35 ; C at t = 2 = 0.20
(0.20 - 0.35) / (2 - 1) = - 0.15 / 1 = - 0.15 mg/mL hr
11) [1.5, 2.0]
(0.20 - 0.26) / (2.0 - 1.5) = - 0.06 / 0.5 = - 0.12 mg/mL hr
111) [2.0, 2.5]
(0.14 - 0.20) / (2.5 - 2.0) = - 0.06 / 0.5 = - 0.12mg/mL hr
iv) [2.0, 3.0]
(0.09 - 0.20) / (3.0 - 2.0) = - 0.11 / 1.0 = - 0.11 mg/mL hr

Find the sum of the first 80 terms of the sequence. Show all work for full credit. 1, -3, -7, -11, ...
Answer:
-12960
Step-by-step explanation:
The formula for the sum of terms =
Sn = n/2[2a + (n - 1) d]
n = number of terms = 80
The given sequence =
1, -3, -7, -11, ...
a = First term = 1
d = common difference
= Second term - First term
= -3 - 1
= -4
Therefore, the sum of the first 80 terms:
S80 = 80/2[2 × 1 + (80 - 1)]-4
= 40[2 + 79]-4
= 40 × 81 × -4
= -12960
The sum of the first 80 terms = -12960

A rectangle is 3 times as long as it is wide. The perimeter is 24 feet. Find the dimensions.
Answer:
Width is 3 units, The Length is 9 units.
Step-by-step explanation:
Three times as much as 3, or 9, is how you find the lengths. This being- 3+3=6 and 9+9=18, 6+18=24, which is the perimeter, therefore 3 and 9 are the dimensions.

what is nearest tenth of 0.273
Answer:
0.3
To round 0.273 to the nearest tenth consider the hundredths’ value of 0.273, which is 7 and equal or more than 5. Therefore, the tenths value of 0.273 increases by 1 to 3.
0.273 rounded to the nearest tenth = 0.3
A rectangle with length of 9 centimeters and width of 5 centimeters. The perimeter of the rectangle is cm. If the rectangle is dilated by a scale factor of 6 to create a new rectangle, the new dimensions are . The perimeter of the new rectangle is ✔ 168 cm. When comparing the new perimeter to the original perimeter, the new perimeter is .
The perimeter of the new rectangle is 150 cm more than the original perimeter.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
A rectangle with a length of 9 centimeters and a width of 5 centimeters.
The perimeter of the rectangle will be
Perimeter = 2 (9 + 5)
Perimeter = 2(14)
Perimeter = 28
If the rectangle is dilated by a scale factor of 6 to create a new rectangle, the new dimensions will be
Length = 6 × 9 = 54 cm
Width = 6 × 5 = 30 cm
The perimeter of the new rectangle is 168 cm.
When comparing the new perimeter to the original perimeter, the new perimeter will be
→ New perimeter - original perimeter
→ 168 - 28
→ 150
The perimeter of the new rectangle is 150 cm more than the original perimeter.

Noah is shopping for new socks. He sees many different options. One bag has 12 socks for $9.99, another bag has 20
socks for $14.99, and a third bag with 10 socks for $19.99. Which is the best deal for socks?
Answer:
the bag with 20 socks for $14.99
Answer:
Second bag having 20 socks for $ 14.99 is the best deal.
Step-by-step explanation:
To find the best deal, you have to find the unit rate
First bag:
Unit rate = 9.99 ÷ 12 = $ 0.8325
Second bag:
unit rate = 14.99 ÷ 20 = $ 0.7495
Third bag:
Unit rate = 19.99 ÷ 10 = $ 1.999
Second bag having 20 socks for $ 14.99 is the best deal.

Answer: x=2
Step-by-step explanation:
We can see that ∠RTU and ∠STR make up ∠STU. Therefore, we add them together and set it equal to 114°.
24x+34x-2=114 [combine like terms]
58x-2=114 [add both sides by 2]
58x=116 [divide both sides by 58]
x=2
