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]

Answer:
90. ( was the full capacity of jug)
to solve this
firstly let the full capacity of jug
be. x
so,
4/5*x = 72
x = 72*5/4
x = 90

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.

What is the value of x in simplest radical form?
Answer:
25, I believe
Step-by-step explanation:
Given a=7 and b=24,
c = 25
Answer:
25
Step-by-step explanation:
a² + b² = c², by Pythagoras
In this case 'x' is the 'c' for hypotenuse length
7² + 24² = x²
49 + 576 = x²
625 = x²
√625 = x
25 = x
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!

During tug of war, team A pulls to the East with 24N of force and team B pulls to the West with 32N of force. Which team will win and what is the net force?
Team B, 8N
Team B, 56N
Team A, 56N
Team A, 8N
Answer: Team B, 8N
Step-by-step explanation: I think it's team be because when doing the problem team a is 24 n to the right while Team B is 32 n to the left, and since they are pointing different directions you would subtract those and then get your answer. Since Team B has the larger force it will be the one to win.

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].

How old are you?
Answer:
The original cable was 5.15 m long.
51: $13.70
53: $16.50
54: $17.85
55: 4.4 miles
56: $49.35
Step-by-step explanation:
The answer to the first question (the one about the cables): So you would solve it by adding the lengths of the cable together.
Cut off piece: 1.65 m Remaining cable: 3.5 m
To find the original length, we need to add the cut off piece and the remaining cable together.
1.65+3.5= 5.15
The original cable was 5.15 m long.

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

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.
