What is the minimum volume of hot air needed to lift a hot air balloon carrying 800kg
Answer:
The minimum volume of hot air needed to lift a hot air balloon carrying 800kg
Is 653.1m³
Step-by-step explanation:
This problem bothers on the density of materials in this problem air
Given data
Volume of air V=?
Mass of air m= 800kg
From tables the density of air is
ρ =1.225 kg/m3
Now to solve for the volume we have
ρ=m/v
v=m/ρ
v=800/1.225
Volume v = 653.1m³

How many solutions does this system have?
y = 3/4x - 5
3x+ 4 y= -20
one
two
an infinite number
no solution
Answer:
one solution
Step-by-step explanation:
y = 3/4x - 5
3x+ 4 y= -20
Substitute the first equation into the second equation
3x+ 4 (3/4x -5)= -20
Distribute
3x +3x - 20 = -20
6x -20 = -20
Add 20 to each side
6x -20+20 = -20+20
6x = 0
x=0
We need to find y
y = 3/4x -5
y =0-5
y = -5
There is one solution
Answer:
A) one
Step-by-step explanation:
y = 3/4x - 5
3x+ 4 y= -20
3x + 4(3x/4 - 5) = -20
3x + 3x - 20 = -20
6x = 0
x = 0
y = -5
One solution: (0,-5)

Use the data to find the interquartile range.
Number of Points Scored at Ten Basketball Games
64 38 50 71 60 58 47 55 70 45
Answer:
17
Step-by-step explanation:
The Interquartile range is the difference between the Quartile 1 and 3. Those quartiles are the median of the left and right side.
Ex: 1, 2, 3, 4, 5
Median = 3, so quartile 1 = median of left side of 3 and quartile 3 = median of right side of 3
First we should organize the data from least to greatest.
38 < 45 < 47 < 50 < 55 < 58 < 60 < 64 < 70 < 71
The median is 56.5.
Quartile 1 = 47
Quartile 3 = 64

what is ordering fraction and give me example please
Answer:
Ordering fractions means putting them in order technically. Such as from least to greatest or greatest to least.
Example:
6/8, 12/18, 15/19
This is a least to greatest example.
Answer: Arranging either in increasing or decreasing order.
Basically it's like Greatest to Less, and Less to Greatest.
Greater to Less
[tex]4/5 > 6/8 > 2/4 > 1/4[/tex]
Less to Greater
[tex]1/4 < 2/4 < 6/8 < 4/5[/tex]
This is just like putting ordinary numbers Greatest to Less or Less to Greatest.
Hakeem is on a tour bus in Paris with his family he sees l'arc de triomphe at an angle of 34°. if the Arc is 162 feet tall, how far away is the bus? round to the nearest tenth.
a. 134.4 ft
b. 90.6 ft
c. 240.2 ft
d. 109.3 ft
Answer:
Side y = 109. 3
Step-by-step explanation:
Step 1 The two sides we are using are Opposite (y)
and Adjacent (162).
Step 2 SOHCAHTOA tells us to use Tangent.
Step 3 Put our values into the tangent function:
tan 34° = Opposite/Adjacent
= y/162
Step 4 Solve:
Start with: tan 34° = y/162
Swap: y/162 = tan 34°
Multiply both sides by 162: y = 162 tan 34°
y = 109.27
y = 109.27 (to 2 decimal places)
Side y = 109. 3
You are choosing between two health clubs. Club A offers membership for a fee of $28 plus a monthly fee of $24. Club B offers membership for a fee of $35 plus a monthly fee of $17. After how many months will the total cost of health club A be at least the total cost for Club B
Answer:
The cost will be the same after 1 month
Step-by-step explanation:
Step 1: set up the equation
club A= 28x+24 club B= 35x+17
club A=club B: 28x+24=35x+17
Step 2: Get rid of the smallest X
28x+24=35x+17
-28 -28
24=7x+17
Step 3: Get rid of the constant next to the variable to isolate the variable
24=7x+17
-17 -17
7=7x
Step 4: Inverse operation to remove variable
7÷7x=7x÷7x

I hope this helped, im not too good at explaining but im positive the solution is correct.
Answer:
With $35, a member is paying 100%.
Since the reduction is 5%, that means his is paying now 95% of $35,
that means $35 x 0.95 = $33.25, So the decrease in fees is 35-33.25 = $1.75
Another method: the reduction was 5% on the $35 or 5% x 35 = 0.05x35=$1.75
Step-by-step explanation:
WC= 15 and CO = 17, what is OW?
We know that triangle COW is a right triangle by the Tangent to a Circle Theorem.
So, we can use Pythagorean Theorem to find OW.
OW² + WC² = CO²
OW² + 15² = 17²
OW² + 225 = 289
OW² = 64
OW = 8
OW, the length of the side of the right triangle, can be found using the Pythagorean theorem. Substituting the given values into the formula and solving for OW gives a result of 8.
Explanation:The question seems to present us with a right triangle, where WC is one leg, CO is the hypotenuse, and OW is the other leg we need to find. We can use the Pythagorean theorem, which says that in a right triangle, the square of the hypotenuse (CO) is equal to the sum of the squares of the other two sides (WC and OW). In a formula, this is a² + b² = c², where c is the hypotenuse.
Substituting the given measurements into the formula we get: WC² + OW² = CO², so OW² = CO² - WC².
OW = sqrt(CO² - WC²) = sqrt((17)² - (15)²) = sqrt(289 - 225) = sqrt(64), so OW = 8.

d. There is not enough information to determine the variability,
Answer: the answer B
Step-by-step explanation:because it has higher smaller numbers than B
This is about variability.
Option B is correct.
Variability is just a measure of the consistency of the values in a given data .
Let's find the mean of both families data set;
Family A: 35, 5, 42, 9, 16, 3, 8, 12
Mean of Family A ages = (35 + 5 + 42 + 9 + 16 + 3 + 8 + 12)/8 = 16.25Mean of Family B ages = (1 + 5 + 29 + 3 + 7 + 35 + 6 + 9)/8 = 11.875Now, the higher the mean, the higher the variance and thus the higher the variability.Thus, we can conclude that; The variability for Family A is higher because its' mean is higher.Read more at; https://brainly.com/question/12477423

A) y + 4 = 3x
B) y − 3x = 0
C) y + 5x = 6
D) y + 1/4x = 2
Answer:
B
Step-by-step explanation:
In a proportional relationship the equation is of the form
y = kx ← k is the constant of proportion
The only equation that can be expressed in this form is
y - 3x = 0 ( add 3x to both sides )
y = 3x ← in proportional form with k = 3
