Complete question :
Andrea rents a bike for a day. The rental charges can be determined by the equation: R = $0.5d, where R is rental charges and d is number of days she rents the bike. Calculate the unit rate.
Answer:
$0.5
Step-by-step explanation:
Given that :
Rental charge, Ris given by the equation = $0.5d
Where, d = number of days
The unit rate = amount charged per day
If d = 1 day
R = $0.5 * 1
R = $0.5

Which is the correct representation of 6/1?
The correct representation of 6/1 is in figure A.
Given:
The four figures with shaded regions and unshaded regions.
To find:
The figure with the correct representation of 6/1.
Solution:
In figure A
Fraction of one box =[tex]\frac{1}{1}[/tex]
There are six individual boxes that will be represented as:
[tex]\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}=\frac{6}{1}[/tex]
In figure B
The number of shaded regions = 5
The total number of regions = 6
The representation will be :
[tex]\frac{\text{Shaded region}}{\text{Total regions}}=\frac{5}{6}[/tex]
In figure C
Fraction of one box =[tex]\frac{1}{1}[/tex]
There are five individual boxes that will be represented as:
[tex]\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}=\frac{5}{1}[/tex]
In figure D
The number of shaded regions = 1
The total number of regions = 1
The representation will be:
[tex]\frac{\text{Shaded region}}{\text{Total regions}}=\frac{1}{6}[/tex]
The correct representation of 6/1 is in figure A.

Answer:
x = 6, ∠ B = 126°
Step-by-step explanation:
∠ A and ∠ B are alternate angles and congruent, so
8x + 78 = 2x + 114 ( subtract 2x from both sides )
6x + 78 = 114 ( subtract 78 from both sides )
6x = 36 ( divide both sides by 6 )
x = 6
Then
∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°

3n + 8 = 35 solve for n
Answer:
Step-by-step explanation:
3n+8=35
subtract 8 on both sides
3n=27
n=9
Answer:
n = 9
Step-by-step explanation:
3n+8=35 –– First, subtract 8 from both sides
3n=27 –– Divide both sides by 3 to get n alone
n = 9
Check:
3(9)+8=35
27+8=35
35=35
If a fire is burning a building and it takes 2 hours to put it out using 2000 gal./min., what minimum diameter cylindrical tank 12 feet high will be needed to store the quantity needed to put out the fire?
Answer:
The minimum diameter of the cylindrical tank needed to store the quantity needed to put out the fire is approximately 58.415 feet.
Step-by-step explanation:
A gallon equals 0.134 cubic feet. First, we determine the amount of water ([tex]Q[/tex]), measured in cubic feet, needed to put out the fire under the assumption that water is consumed at constant rate:
[tex]Q = \dot Q \cdot \Delta t[/tex] (1)
Where:
[tex]\dot Q[/tex] - Volume rate, measured in feet per minute.
[tex]\Delta t[/tex] - Time, measured in minutes.
If we know that [tex]\dot Q = 2000\,\frac{gal}{min}[/tex] and [tex]\Delta t = 120\,min[/tex], then the amount of water is:
[tex]Q = \left(2000\,\frac{gal}{min} \right)\cdot (120\,min) \cdot \left(0.134\,\frac{ft^{3}}{gal} \right)[/tex]
[tex]Q = 32160\,ft^{3}[/tex]
And the diameter of the cylindrical tank based on the capacity found above is determined by volume formula for a cylinder:
[tex]Q = \frac{\pi}{4}\cdot D^{2}\cdot h[/tex] (2)
Where:
[tex]D[/tex] - Diameter, measured in feet.
[tex]h[/tex] - Height, measured in feet.
If we know that [tex]Q = 32160\,ft^{3}[/tex] and [tex]h = 12\,ft[/tex], then the minimum diameter is:
[tex]D^{2} = \frac{4\cdot Q}{\pi\cdot h}[/tex]
[tex]D = 2\cdot \sqrt{\frac{Q}{\pi\cdot h} }[/tex]
[tex]D = 2\cdot \sqrt{\frac{32160\,ft^{3}}{\pi\cdot (12\,ft)} }[/tex]
[tex]D \approx 58.415\,ft[/tex]
The minimum diameter of the cylindrical tank needed to store the quantity needed to put out the fire is approximately 58.415 feet.

1225 times 3.14=3846.5
Ace Car Rentals charges $20 per day plus a $10 service charge to rent one of its compact cars. The total cost can be represented by the equation y = 20x + 10, where x is the number of days and y is the total cost.
Answer:
Step-by-step explanation:
Graph of the equation 20x + 10 is plotted and the total cost for 7 days is $150
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Ace Car Rentals that charges $20 per day plus a $10 service charge to rent one of its compact cars. The total cost can be represented by the equation y = 20x + 10, where [x] is the number of days and [y] is the total cost.
The graph of the equation 20x + 10 is plotted and attached. To find the total cost of renting the car for 7 days, find the y - coordinate corresponding to x = 7 on graph. See the graph [2]. We get the total cost of $150 for 7 days.
Therefore, graph of the equation 20x + 10 is plotted and the total cost for 7 days is $150

5(2+c)=45+5c no solution
Answer:
Step-by-step explanation:
