Two beach rental companies compared their sales from last weekend. Both companies rent out jet skis and kayaks, and they charge the same prices. Will's Watersports made a total of $780 from renting 12 jet skis and 9 kayaks. Family Fun Rentals made a total of $570 from renting 7 jet skis and 11 kayaks. What is the cost of each type of rental?
Answer:
Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.
Step-by-step explanation:
Since they both rent the vehicles at the same price, "x" for jet skis and "y" for kayaks", we can create equations for each store and a system of equations for these, as shown below:
Watersports:
12*x + 9*y = 780
Fun Rentals:
7*x + 11*y = 570
System:
[tex]\left \{ {{12*x + 9*y=780} \atop {7*x + 11*y=570}} \right.[/tex]
We can isolate "x" on the first equation:
[tex]x = \frac{780 - 9*y}{12}[/tex]
And use it on the second:
[tex]7*[\frac{780 - 9*y}{12}] + 11*y = 570\\5460 -63*y = 6840 - 132*y\\132*y - 63*y = 6840 - 5460\\69*y = 1380\\y = 20\\[/tex]
We can now use this value to find "x":
[tex]x = \frac{780 - 9*20}{12} = 50[/tex]
Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.

Find the slope of the line graphed
Answer:
The slope is 3/2
Step-by-step explanation:
To find slope you do rise over run
Rise being how much you go up or go down
Run being how much you move sideways
Always measure Rise first, it is the numerator and then Run as the denominator.
Answer:
m= 3/2.
Step-by-step explanation:
To find the slope, use the two points shown in the graph which as (-1, 2) and (1, 5). Plug these into the slope formula [tex](m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}} )[/tex]
[tex]m= \frac{5-2 }{{1+1}}[/tex]
[tex]m= \frac{3}{2}[/tex]
Therefore, the slope of the graph is 3/2.
While shopping for clothes, Tracy spent $26 less than 2 times what Curtis spent. Tracy spent $12. Write and solve an equation to find how much Curtis spent. Let x represent how much Curtis spent.
Answer:
Curtis spent $76
(x=76)
Step-by-step explanation:
12 +26
Tracy spent 12 dollars, which was 26 dollars less two times what Curtis spent

Answer:
[tex]- 7 + \frac{2}{3}n = 13 : n = 30[/tex]
Step-by-step explanation:
[tex]-7+\frac{2}{3}n=13[/tex]
Add [tex]7[/tex] to both sides:
[tex]-7+\frac{2}{3}n+7=13+7[/tex]
Simplify:
[tex]\frac{2}{3}n=20[/tex]
Multiply both sides by [tex]3[/tex]:
[tex]3 * \frac{2}{3}n=20 * 3[/tex]
Simplify:
[tex]2n=60[/tex]
Divide both sides by [tex]2[/tex]:
[tex]\frac{2n}{2}=\frac{60}{2}[/tex]
Simplify:
[tex]n = 30[/tex]

There are eight black socks six blue socks and 14 White Sox in a drawer if one sock is randomly chosen from the drawer than what is the probability that the sock not be blue
Answer:
The probability that the socks picked is not blue is 11/14
Step-by-step explanation:
In this question, we are to calculate that a socks selected from random from the group of socks given in the question is not a blue socks.
This means the socks would either be a black or a white socks
Firstly, we find the total number of socks = 8 + 6 + 14 = 28 socks
Now the probability of picking a blue socks will be 6/28 = 3/14
We must understand that the probability of not picking a blue socks = 1 - the probability of picking a blue socks
Thus, the probability of not picking a blue socks will be 1 - 3/14 = 11/14
Answer:
The probability that a sock chosen at random is not blue P = 11/14 = 0.786
Step-by-step explanation:
Probability is the chances of getting a particular outcome.
Given:
Black socks = 8
Blue socks = 6
White socks = 14
Total = 8+6+14 =28
The probability that a sock chosen at random is not blue P;
P = number of non-blue socks ÷ total number of socks
Number of non blue socks = black + white socks = 8+14 = 22
Substituting the values;
P = 22/28 = 11/14
P = 11/14 = 0.786
two rangers at stations located 10 miles apart both see a camper distress signal in the distance the signal is at a compass bearing of 70 degrees from the north station and 40 degrees from the south station find the distance to the angle signal from south station to the nearest hundred
Answer:
10 miles
Step-by-step explanation:
∠1 = 70° and ∠3 = 40°. Angles of a triangle add up to 180°, so ∠2 = 70°.
Using law of sines:
10 / sin(∠2) = x / sin(∠1)
10 / sin(70°) = x / sin(70°)
x = 10
Which one of these grids is shaded red and blue in the ratio 1 : 1/3 ?
The grid among the answer choices which is shaded 1 : 1/3 is; Choice A.
Which Grid is shaded red and blue in the ratio 1 : 1/3 ?It follows from the task content that the ratio of red to blue in each grid is as follows;
Choice A; 9 : 3 = 1 :1/3Choice B; 8 : 4 = 1 : 1/2Choice C; 7 : 5Choice D; 10 : 2 = 5: 1Choice E; 3: 9 = 1: 3Choice F; 6:6 = 1 : 1On this note, it therefore follows that the grid with the required ratio is Choice A.

HOW DO I START?
Don't worry, you know that this problem only has two small steps, and it's done, it should take less than 45 seconds to complete.
WE ALWAYS WANT TO ISOLATE THE VARIABLE TO FIND Y: MAKE IT BE ALONE!
STEP 1: Subtract 12 from both sides, to start getting 5y alone.
NOW YOU HAVE: 5y = 20
STEP 2: Divide by 5 from both sides, to get the Y fully alone.
NOW YOU HAVE: y = 4
