A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours
Answer:
Additional fee or hour = $8.5
y = $2 + 8.5x
Step-by-step explanation:
Given that :
Total paid = $36
Number of hours = 4
Initial rental fee = $2
Additional fee per hour = a
Total amount = initial rental fee + additional fee per hour * number of hours
36 = 2 + 4a
36 - 2 = 4a
34 = 4a
a = 8.5
Hourly fee = $8.5
Therefore, the cost formula
y = initial fee + regular fee * number of hours
y = $2 + 8.5x

How do you divide Fractions?
Tysm!
So for example we have
1/2 divided by 1/6
What we will do it’s
Leave the first one As it is
Turn the second fraction (the one you want to divide by) upside down
The change the divide to multiply
Multiply the first fraction by that reciprocal
Simplify the fraction (if needed)
So it’s will be like this

The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day. The number of red carnations sold was 3 more than 2 times the number of pink carnations sold. Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 . How many of each carnation were sold?
Answer:
The number of :
Red carnations sold = x = 687 carnations
Pink carnations sold = y = 342 carnations
How many of each carnation were
Step-by-step explanation:
Let us represent
The number of :
Red carnations = x
Pink carnations = y
The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.
The number of red carnations sold was 3 more than 2 times the number of pink carnations sold.
x = 3 + 2y .....Equation 1
Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 .
$0.50 × x + 0.75 × y = $600
0.5x + 0.75y = 600...... Equation 2
Using substitution method:
Let us substitute, 3 + 2y for x in Equation 2
0.5(3 + 2y) + 0.75y = 600
1.5 + y + 0.75y = 600
y + 0.75y = 600 - 1.5
1.75y = 598.5
y = 598.5/ 1.75
y = 342 carnations.
Solving for x
x = 3 + 2y .....Equation 1
x = 3 + 2(342)
x = 3 + 684
x = 687 carnations
Therefore, The number of :
Red carnations = x = 687 carnations
Pink carnations = y = 342 carnations

Using the common denominator, what is an equivalent fraction for 2/7
?
Answer:
The fraction 4/14 is equal to 2/7 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (2/7) by the same interger number, ie, multiply by 2, 3, 4, 5, 6
A hot air balloon is descending at a rate of 287 feet per minute.
Find the total change in elevation of the balloon in 4 minutes.
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptA hot air balloon is descending at a rate of 287 feet per minute.
Thus, the rate of change m = -287
The negative sign indicates that a hot air balloon is descending.
Let y be elevation.
Let x be the time (in minutes)
As there is no mentioning of the initial height.
Thus, the y-intercept b = 0
now substituting m = -287 and b = 0
y = mx + b
y = -287x + 0
y = -287x
In order to determine the total change in elevation of the balloon in 4 minutes, we need to substitute x = 4 in the equation y = -287x.
Thus, the total change in elevation of the balloon in 4 minutes will be:
y = -287x
y = -287(4)
y = -1148 feet
The negative sign indicates that that the elevation is decreasing.
ACFG is a parallelogram, If AX = 4y + 3 and XF = 2y + 7, find AX.

The value of length AX of parallelogram is 11.
What is parallelogram?A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposite sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
∵ ACFG is a parallelogram, therefore length of diagonal will be equal
∴AX = XF
4y+3 = 2y+7
4y-2y = 7-3
2y = 4
y = 2
Therefore, length of AX is :
AX = 4y+3
= 4×2+3
= 11

Sharon owns a car lot in Virginia Beach. For every car that parks in her parking lot, she charges $5.00 per day. She uses this equation to determine her daily income: y = 5x, where x is the number of cars and y is the amount of money earned. What is true about this function?
Answer and Step-by-step explanation:
Given the function y = 5x where x is the total number of cars parked in her lot and y is the total money earned. Since x is the independent variable as the money earned, y, depends on the amount of cars parked, we can say that the domain (the actual values the independent variable can assume) of this function is:
x = {0, 1, 2, 3, . . .}
This is because x, the number of cars, can never be a negative number..
Also, the range, the set of all the values of the dependent variable y, is: {all the numbers divisible by 5, including 0}

How can you isolate the variable in this equation? x + 6 = 13
You can isolate the variable by subtracting 6 from both sides.
e.g.
x + 6 = 13
- 6 - 6
Now we have x = 7, which not only isolates the variable but solves for x.
If you don't know why we can subtract from both sides, look up the Addition Property of Equality and Subtraction Property of Equality.

to find the y's, go back and plug in
Prob 1: y=(3+4) =7
Prob 2: y=[3(10)+5] =35
Prob 3: y=(-2/3) =-2/3
Answer:
1.)
y = 2x + 1
y = x + 4
Substitute
2x + 1 = x + 4
Subtract 1 on both sides
2x + 1 - 1 = x + 4 - 1
2x = x + 3
Subtract x on both sides
2x - x = x - x + 3
x = 3
Now that we have x we can use that for finding y
y = x + 4
y = 3 + 4
y = 7
x = 3
y = 4
( 3, 4 )
__________________________________________________________
2.)
y = 4x - 5
y = 3x + 5
Substitute
4x - 5 = 3x + 5
Add 5 on both sides
4x - 5 + 5 = 3x + 5 + 5
4x = 3x + 10
Subtract 3x on both sides
4x - 3x = 3x - 3x + 10
x = 10
Now that we have x, we can use that to find y
y = 3x + 5
y = 3 (10) + 5
y = 30 + 5
y = 35
x = 10
y = 35
( 10, 35)
__________________________________________________________
3.)
y = x
y = 4x + 2
Substitute
x = 4x + 2
Subtract 4x on both sides
x - 4x = 4x - 4x + 2
-3x = 2
Divide -3 on both sides to isolate the variable
-3x/-3 = 2/-3
x = -2/3
Now that we have that we can use it to find y
y = x
y = -2/3
x = -2/3
y = -2/3

The current in one part of a series circuit is 3 – 2j amps. The current in
another part of the circuit is 2 + 4j amps. Find the total amps in the circuit. .
Answer:
5 + 2j Amps
Step-by-step explanation:
current in part one = 3 -2j A
Current in second part = 2 + 4j
Total amps in the circuit = 3 - 2j + 2 + 4j
Collect the like terms
Total amps in the circuit = 3+2-2j+4j
Total amps in the circuit = 5 + 2j
Hence the total amps in the circuit is 5 + 2j Amps
The total amps in the circuit described is; 5 +2j
Since current flows in the same direction in a series circuit.
We can evaluate the total current that flows in the circuit as follows;
Total current = 1st part current + 2nd part currentTotal current = 3 – 2j + 2 + 4j Total amps = 5 +2j.Read more;

What is the common ratio of the following geometric sequence? 6,9,27/2,81/4,...
a. r=-2
b. r=2
c. r=3/2
d. r=2/3
Answer:
C
Step-by-step explanation:
The common ratio (r) can be found as
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex] → C
The common ratio of the geometric sequence is c. r = 3/2.
To determine the common ratio of a geometric sequence, we need to find the ratio between consecutive terms.
In the given sequence: 6, 9, 27 / 2, 81 / 4, ...
To find the ratio between consecutive terms, we divide each term by its preceding term.
9 / 6 = 3 / 2
(27 / 2) / 9 = 3 / 2
(81 /4 ) / (27 / 2) = 3 / 2
We observe that the ratio between consecutive terms is always 3 / 2.
Therefore, the common ratio of the geometric sequence is c. r = 3/2.

A rectangular parking lot has an area of 1650 yd.² the length of the parking lot is 55 yards what is the width of the parking lot in yards
Answer:
The width of parking lot is 30 yards.
Step-by-step explanation:
Given that:
Area of rectangular parking lot = 1650 yards square
Length of parking lot = 55 yards
Width of parking lot = x yards
Area of rectangle is given by:
A = Length * Width
1650 = 55x
Dividing both sides by 55
[tex]\frac{55x}{55}=\frac{1650}{55}\\x=30[/tex]
Hence,
The width of parking lot is 30 yards.
