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.

b.
Brand A, Brand C, Brand B
c.
Brand B, Brand A, Brand C
d.
Brand C, Brand A, Brand B
Answers
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.
A necklace and earrings cost $144. Six necklaces and five pairs of earrings cost $825
Answers
Step-by-step explanation:
let necklace : x
let earrings : y
x+y=144 -1st eqn
6x+5y=825 -2nd eqn
y=144-X -3rd eqn
substitute eqn into 2nd eqn
6x+5(144-x)= 825
6x +720-5X =825 (expanded)
X = 825-720
X =105
substitute "X=105" into 1st eqn
(105)+y=144
y= 144-105
y=39
1 necklace = 105$
1 pair of earrings = 39$
(to check back: substitute the value into the original eqn)

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
Answers
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]

what is a formula for the nth term of the given sequence?
12,6,3...
Answers
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].
