Answer:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Step-by-step explanation:
The volume of a rectangular prism of length L, depth W and height H is
V = L * W * H.
Thus,
in this case,
V = (2x + 1)(x - 2)(3x).
The order in which we multiply these quantities together is immaterial.
Working from left to right, we get:
V = (2x^2 - 3x - 2)(3x), and then:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Find the area of the circle. Use 3.14 for .
20 yd
Answer:
314 yd²
Step-by-step explanation:
A = πr²
Use the formula.
A = π(10)²
Substitute. Use 10 for r.
A ≈ 3.14 × 10²
Substitute. Use 3.14 for π.
A ≈ 3.14 × 100 Evaluate the power.
A ≈ 314 Multiply.
The area of the circle is about 314 yd².

Answer:1500 grams
Step-by-step explanation:
The atmospheric pressure p on a balloon or an aircraft decreases with increasing height. This pressure, measured in milimeters of mercury, is related to the heighth (in kilometers) above sea level by the formula p = 760 -0.145
(a) Find the height of an aircraft if the atmospheric pressure is 246 millimeters of mercury
Answer:
[tex]h = 3544.83km[/tex]
Step-by-step explanation:
Given
[tex]P= 760 - 0.145h[/tex]
Required
Find h when P = 246
Substitute 246 for P
[tex]246= 760 - 0.145h[/tex]
Collect like terms
[tex]246- 760 = - 0.145h[/tex]
[tex]-514= - 0.145h[/tex]
Make h the subject
[tex]h = \frac{-514}{-0.145}[/tex]
[tex]h = 3544.83km[/tex]

Find the area of the figure.
The area is
square units.
Answer:
36 square units
Step-by-step explanation:
split the figure so that it's a triangle and a rectangle. Find the area of the rectangle (base x height or 6 x 4), which is 24 square units. Then, find the area of the triangle ((base x height)/2 or (6 x 4)/2), which would be 12 units. Then add those units up (24 + 12) and you get 36.

If a value of a car worth 50000 is deprecating half yearly at 10 percent pa the correct expression to express its value after 2 years is?
Answer:
50,000 x 0.90 ^ 4 = X
Step-by-step explanation:
Since the value of a car worth $ 50,000 is deprecating half yearly at 10 percent, the correct expression to express its value after 2 years is determined through the following calculation:
50,000 x 0.90 ^ 4 = X
32.805 = X
Thus, after 2 years with a semi-annual depreciation of 10%, the car will be worth $ 32,805.
According to exponent rules, when we divide the expressions we _______ the exponents.

Given the following prices and unit conversions, rank the brands from lowest to highest unit price.
Brand A: $1.48 for 2.5 pounds
Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams
Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces
a.
Brand A, Brand B, Brand C
b.
Brand A, Brand C, Brand B
c.
Brand B, Brand A, Brand C
d.
Brand C, Brand A, Brand B
Answer:
d.
Brand C, Brand A, Brand B
Step-by-step explanation:
To find the unit price, we divide the price by the number of pounds.
Brand A: $1.48 for 2.5 pounds
Unit price of:
[tex]\frac{1.48}{2.5} = 0.592[/tex]
Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams
907.18/453.59 = 2 pounds
Unit price of:
[tex]\frac{1.3}{2} = 0.65[/tex]
Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces
50/16 = 3.125 pounds
Unit price of:
[tex]\frac{1.55}{3.125} = 0.496[/tex]
From lowest to highest unit price:
C, A and B, so option d.
Answer:
D
Step-by-step explanation:
Unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to get a usable number.
What is the midpoint of (1, 8) (9, 6)
Answer:
(5,7)

what is a formula for the nth term of the given sequence?
12,6,3...
Given:
The sequence is:
12, 6, 3, ...
To find:
The formula for the nth term of the given sequence.
Solution:
We have,
12, 6, 3, ...
Here, first term is 12.
Clearly, [tex]\dfrac{6}{12}=\dfrac{3}{6}[/tex]. Since the given sequence has a common ratio [tex]r=dfrac{1}{2}[/tex], therefore it is a geometric sequence.
The formula for the nth term of the given sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
[tex]a_n=12\left(\dfrac{1}{2}\right)^{n-1}[/tex]
Therefore, the formula for the nth term of the given sequence is [tex]a_n=12\left(\dfrac{1}{2}\right)^{n-1}[/tex].

Yuk noticed that out of 24 students entering the building at Willowville Elementary School this morning, 8 of them were carrying a lunch box. If these students are representative of the entire school, how many of the Willowville's 84 students would you expect to have brought a lunch box?
Answer:
the students that brought a lunch box is 28
Step-by-step explanation:
The computation of the students that brought a lunch box is shown below:
= Entire school students × students that carry a lunch box ÷ entering students
= 84 students × 8 ÷ 24 students
= 28 students
Hence, the students that brought a lunch box is 28
