Step-by-step explanation:
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.

y values: 3,4,5,6
x values: 5,10,15,20
Step-by-step explanation:
I used a graphing calculator but y is increasing by one and x increases by 5 each time
Answer:
See below.
Step-by-step explanation:
A's number is x. B's number is y.
x = 5y - 10
First row: What is x when y= 3?
x = 5y - 10 = 5*3 - 10 = 15 - 10 = 5; x = 5
Second row: What is x when y = 4?
x = 5y - 10 = 5*4 - 10 = 20 - 10 = 10; x = 10
Third row: What is y when x = 15?
x = 5y - 10
Add 10 both sides x + 10 = 5y - 10 +10
x + 10 = 5y
But we're told x = 15, so 15 + 10 = 5y
25 = 5y
Divide both sides by 5 25/5 = 5y/5
5 = y y = 5
Fourth row: What is x when y = 6?
x = 5y - 10 = 5*6 - 10 = 30 - 10 = 20; x = 20

Answer:
C. 3 to 18, 5 to 30 is equal
Step-by-step explanation:
Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts
early and is already on page 40.
d=days
p=pages
Ashley: p=10d
Carly: p=8d+40
On day ____, both girls should be on page ____.
Answer:
On day 20, they should both be on page 200
Step-by-step explanation:
I set the 2 equations up:
10d=8d+40 and then subtracted 8d from both sides
2d=40 and then divided both sides by 2
d=20
I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)
Hope this helps!
What would measure a be?
Answer:
a = 40 degrees
Step-by-step explanation:
the inscribed angle of 200 degree arc is 100 degrees.
the sum of all the interior angles of a triangle is 180 degrees so:
angle a = 180 - 100 - 40 = 40 degrees
I don’t know I think u times both of them 40 and 36 then divide by 4 then times by 2 i don’t know
What is the question?
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 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.

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