What is the area of this polygon?
A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2
Answer:
C) 40 cm²
Step-by-step explanation:
area of top triangle = 1/2 x 8 x 6 = 24 cm²
area of bottom triangle = 1/2 x 8 x 4 = 16 cm²
24 cm² + 16 cm² = 40 cm²

Step-by-step explanation:
Write an explicit formula for a , the nth term of the sequence 7, 14, 28, ...
Answer:
The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).
Here are the first few terms of the sequence:
n = 1: a_1 = 7
n = 2: a_2 = 14
n = 3: a_3 = 28
n = 4: a_4 = 56
n = 5: a_5 = 112
As you can see, the formula works for all values of n.

What fraction plus what fraction that are the same equals to 3/4 シ
Answer:
easy. 375/1000 + 375/1000 = 3/4
Step-by-step explanation:
divide 3/4 by two. Your answer should be 0.375.
Then you convert 0.375 into a fraction, which would be 375/1000
whats the slope and y-intercept sorry i keep getting it wrong
Answer:
-2 & 3/2
Step-by-step explanation:
=> -4x - 2y = -3
=> -4x + 3 = 2y
=> (-4/2)x + (3/2) = y
Compare this to y=mx+c
m=slope = -4/2 = - 2
y-intercept = c = 3/2
Answer:
2 & 3/2

explain to me how to find the volume of a shape like im a 5 yr old because thats the best way ill understand it.
Answer:
length x width x height
Step-by-step explanation:
I'm 43
Answer:
Length x height x width.
Step-by-step explanation:
Examples:
1 x 2 x 3 = 1 x 2 = 2 + 0 = 2 x 3 = 3 + 3 = 6 so the answer is 6.
2 x 3 x 2 = 2 x 3 = 3 + 3 = 6 x 2 = 6 + 6 = 12 so the answer is 12.
Here's one more in a different way:
3 x 5 x 4 = 5 + 5 + 5 = 15 = 15 + 15 = 30 x 2 = 30 + 30 = 60.

In this discussion, you have the opportunity to have some hands-on fun. With a
tape measure determine the diameter and circumference of at least three circular
objects. Calculate the ratio of the circumference to the diameter.
Take a look at Khianna's post:
I used a tape measure to determine the diameter and circumference of an orange
juice can, a trash can, and a lamp shade. Here is what I found:
Circumference
4.65 in
Ratio
3.1
OJ Can
Diameter
1.5 in
8 in
6 in
Trash Can
3.12
24.96 in
18.8 in
Lamp Shade
3.13
The ratio was close to Pi, but never actually equaled 3.14, maybe because of an
error when I measured the objects.
After you complete your measurements, use the diameter to calculate the exact
circumference of each object as shown on the next page.
Use the diameter to calculate the exact.value of the circumference of each object.
Look how Khianna added to her post:
If I used the diameter I measured, the exact value for each object's circumference would be: diameter or circumference OJ can 1.5 in 1.5 pi and 4.71 in trashcan eight in a pie in 25.12 in lampshade six and six pie and 18.84 in
Use a measuring tape to determine the diameter and approximate for conference of three household items
Find the ratio of the circumference to the diameter for each circle identify what the value of this ratio should be
Use pi and the diameter to calculate the exact value of the circumference
Use the approximation pi equals 3.14 to find the approximate circumference
Answer:
Diameter x Pi = Circumference

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
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).
SetupUsing the given formula with the relevant values, we have ...
A = (300 mg)·(1/2)^(12/8)
EvaluationUsing 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
Data represented by quantities is called ______ data.
A. categorical
B. numerical
Please answer this correct
Answer:
C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.

You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?
Answer:
Hello there! :) The tip they would leave you would be of $23.23
Step-by-step explanation:
The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.
