Which expression represents the area of triangle ABC in square meters?
A. 1/2 x 14 x 57
B. 1/2 x 14 x 64
C. 1/2 x 24 x 40
D. 1/2 x 24 x 57

Answers

Answer:

A. 1/2 x 14 x 57

Step-by-step explanation:

The formula for the area of a triangle is base x height x 1/2

To calculate the base you would need to add the two numbers on the bottom of the triangle: 20 + 37 = 57

The photo shows that the height is 14 so it would be

1/2 x 14 x 57

Formula of area of triangle-1/2

The base is 20+37 =57

so the answer is 1/2*57*14

Total surface area of triangular prism= (l₁ +l₂ + b)* height

                                                                 = ( 6 + 6 + 6) * 15

                                                                 = 18 * 15

                                                                 = 270 cm²

2) length = l = 8.2 in

Width = w = 3.4 in

height = h = 2

Total surface area of rectangular prism = 2*(lw + wh + hl)

= 2*(8.2*3.4  +  3.4*2  + 2*8.2)

=2 *( 27.88 + 6.8 + 16.4)

= 2 * 51.08

= 102.16

Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours

The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:


A=A^0⋅(12)^t/h
If Scott was administered 300 mg of Lithium, which of the following represents how much lithium, rounded to the nearest hundredth of a mg, could be left in Scott's blood stream after 12 hours?

Select one:
A. 157.23
B. 106.07
C. 212.17
D. 188.99

Answers

Answer:

  B.  106.07

Step-by-step explanation:

To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).

Setup

Using the given formula with the relevant values, we have ...

  A = (300 mg)·(1/2)^(12/8)

Evaluation

Using a calculator to evaluate this expression, we find the amount of Lithium remaining in Scott's system after 12 hours to be ...

  A ≈ 106.07 mg

Answer:

24 ounces for $2.99

Step-by-step explanation:

Because that would make the cost into 3 dollars, and It would be cheaper to do it that way. The reason I said this is because I remember I had to pay for something that cost 3 dollars, and it was a drink for 24 ounces, so yes, and that is why I think 24 ounces for $2.99.

The answer is two times of square root of 8
answer:

C: 400

explanation:

basically on the graph what you do is you find the first term in the two subject textbook title. so for physics - biology, you would go to the horizontal axis and find the physics section. then what you do is find the biology section on the vertical axis. find the square they intersect at. the number inside that square is the number of physics - biology books sold per month.

if you do the same thing for the history - chemistry books, you’ll find that 300 of those are sold per month.

the difference between 700 and 300 is 400, giving you option C as your answer.
