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.
A family wants to rent a car to go on vacation. Company A charges $30.50 and 8¢ per mile. Company B charges $75.50 and 12¢ per mile. How much more does Company B charge for x miles than Company A? PLZ HeLp NoW!! Its due today!!!!!!!!!!!!
Answer:
$40 and 10 x cents.
Step-by-step explanation:
$75.50 and 18 cents - $35.50 and 8 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.
Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.
7568 - 3558 cents = 4010 cents. For x miles, 4010X cents.
Step-by-step explanation:
$75.50 and 18 cents - $35.50 and 8 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.
Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.
7568 - 3558 cents = 4010 cents. For x miles, 4010X cents.

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

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.

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.

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

ANSWER THESE TWO QUESTIONS FOR ME:
1. If the surface area of a cube is 390 cm², then which best describes the length of the side of the cube?
A. less than 7 cm
B. between 7 cm and 8 cm
C. between 8 cm and 9 cm
D. greater than 9 cm
2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?
Answer:
65^2
Step-by-step explanation:
if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.
#1:
Between 8 cm and 9 cm
Work:
SA = 6s^2
390 = 6 s^2
390/6 = 6s^2 /6
65 = s^2
sqrt(65) = s
s = 8.06
#2:
The total surface area of the triangular pyramid is 107 * square feet.
What is a triangular pyramid?
Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.
We are given that;
The length of median from outer triangle to side of the inner triangle is 8 ft
Side of inner equilateral triangle is 12 ft
Now,
First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:
a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).
a^2 + (m/2)^2 = b^2
b^2 = 6^2 + 8^2/4
b^2 = 36 + 4
b^2 = 40
b = sqrt(40)
b = 2 * sqrt(10)
So the height of the outer triangle is:
h = b * sqrt(3)/2
h = sqrt(30)
Now we can find the area of each equilateral triangle using the formula:
A = (sqrt(3)/4) * s^2
For the inner triangle:
A_inner = (sqrt(3)/4) * 12^2
A_inner = 36 * sqrt(3)
For the outer triangle:
Now we can find the area of the base, which is just the area of the inner equilateral triangle:
A_base = A_inner
A_base = 36 *
Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:
SA = A_inner + 3 * A_outer + A_base
