A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. What is the cost of renting the canoe for 6 hours?
Answers
Answer:
use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.
y=30x+20
to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x
y=(30×6)+20
y=180+20=$200
Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost

Twinkle toes tony kick the football and it landed 100 feet from where he kicked it also reach a maximum height of 125 feet write an equation that models the path of the ball while it was in the air
Answers
Answer:
The equation that models the path of the ball is y = 5·x - 0.05·x²
Step-by-step explanation:
The given information are;
The distance the football landed from where it was kicked = 100 feet
The maximum height the football reached = 125 feet
The equation that models the path of the ball is that of the equation of parabola in vertex form, given as follows;
y = a·(x - h)² + k
Where;
(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)
Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;
The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)
We have;
The coordinate of the highest point reached by the ball = (50, 125)
Therefore;
(h, k) = (50, 125)
Substituting the above values in the equation of the parabola gives;
y = a·(x - 50)² + 125
At x = 100, y = 0, which gives;
0 = a·(100 - 50)² + 125 = a·2500 + 125
0 = a·2500 + 125
a = -125/2500 = -0.05
Therefore, we have;
y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125
y = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x
y = -0.05·x² + 5·x
The equation that models the path of the ball is y = -0.05·x² + 5·x.

24-10b=9 what is the missing variable equal to
Answers
Answer:
b = 1.5
Step-by-step explanation:
Lets first set up the equation:
24 - 10b = 9
Okay now lets add 10b on both sides:
24 = 9 + 10b
Now let's subtract 9 from both sides so we can get the variable b by its self:
15 = 10b
Okay now we can divide each side by 10:
1.5 = b
Answer:
24-10(1.5)=9
b = 1.5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
b = 3 /2
Decimal Form:
b = 1.5
10(1.5) = 15
24 - 15 = 9

One pack of pencils currently costs $1.19. The cost of one pack of pencils is projected to increase by 135% in the next 5 years. What is the projected cost of a pack of pencils 5 years from now? (Round your answer to the nearest cent.)
Answers
Answer: $2.80
Step-by-step explanation:
Given: Cost of one pack of pencils = $1.19
The cost of one pack of pencils is projected to increase by 135% in the next 5 years.
So, the cost of pack of pencils after 5 years = $1.19 + 135% of $1.19
= $ (1.19+1.35(1.19)) [135% = 1.35 since we divide each percent by 100 to convert in decimal]
= $ (1.19+1.6065 )
= $ 2.7965 ≈ $ 2.80 [Rounded to the nearest cent]
hence, the projected cost of a pack of pencils 5 years from now = $2.80
#12: Kara is deciding between The Lyme Point Inn and Ever After Farms for her wedding reception. The Lyme Point Inn charges $3,000 for the venue and $100 for each meal. Ever After Farm charges $5,400 for the venue and $70 for each meal. Write and solve an equation to find the number of meals at which the total cost charged by the two venues would be the same. *
Answers
Answer: Required euqtaion: 3000+100x = 5400+70x
Solution: x=80 i.e. The number of meals at which the total cost charged by the two venues would be the same = 80
Step-by-step explanation:
Let x= Number of meals.
For Lyme Point Inn, cost for x meals = 100x
Total cost = 3000+100x
For Ever After Farm, cost for x meals = 70x
Total cost = 5400+70x
When both cots same, then
3000+100x = 5400+70x
⇒ 100x-70x= 5400-3000
⇒ 30x=2400
⇒ x= 80
Hence, the number of meals at which the total cost charged by the two venues would be the same. =80

In ΔHIJ, \text{m}\angle H = (4x+1)^{\circ}m∠H=(4x+1) ∘ , \text{m}\angle I = (2x-6)^{\circ}m∠I=(2x−6) ∘ , and \text{m}\angle J = (6x-7)^{\circ}m∠J=(6x−7) ∘ . Find \text{m}\angle J.M∠J.
Answers
Given:
In ΔHIJ, m∠H=(4x+1)° , m∠I=(2x−6)°, and m∠J=(6x−7)° .
To find:
The m∠J.
Solution:
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
In ΔHIJ,
[tex]m\angle H+m\angle I+m\angle J=180^\circ[/tex] [Angle sum property]
[tex](4x+1)^\circ+(2x-6)^\circ+(6x-7)^\circ=180^\circ[/tex]
[tex](12x-12)^\circ=180^\circ[/tex]
[tex]12x-12=180[/tex]
Add 12 on both sides.
[tex]12x=180+12[/tex]
[tex]12x=192[/tex]
Divide both sides by 12.
[tex]x=16[/tex]
Now,
[tex]m\angle J=(6x-7)^\circ[/tex]
[tex]m\angle J=(6(16)-7)^\circ[/tex]
[tex]m\angle J=(96-7)^\circ[/tex]
[tex]m\angle J=89^\circ[/tex]
Therefore, the measure of angle J is 89 degrees.

2) If two angles are 45 degrees then they are complementary and congruent.
Explanation: Complementary angles add up to 90 degrees and congruent angles are angles that are equal. Two 45 degree angles are equal to each other and add up to 90 degrees. The first statement is false because there are many combinations of angles that add up to 90 degrees that are not the same. (30 degrees and 60 degrees)
