3.08 milesStep-by-step explanation:
Total distance = 10 milesTotal time = 2 hoursDistance walked = xSpeed walked = 2 mphDistance cycled = 10 - xSpeed cycled = 15 mphUsing the given data we can have the equation below to the time:
x/2 + (10 - x)/15 = 230x/2 + 30(10 - x)/15 = 30(2)15x + 20 - 2x = 6013x = 60 - 2013x = 40x = 40/13x = 3.08 miles rounded to 2 decimal placeshi can someone ss this and draw arrows? im so confused

You and your friends are having a car wash to raise money for the school chorus you spend $15 on supplies and charge 6 dollars per car at the end of the day you profit 93 dollers how many cars did you and your friends wash
Answer:
Step-by-step explanation:
From the information provided, you know that the profit would be equal to the price per car for the number of cars washed minus the amount you spent on supplies, which would be:
P=6x-15, where:
P is the profit
x is the amount of cars washed
Also, you know that the profit is 93, so you can replace P in the formula and solve for x:
93=6x-15
93+15=6x
108=6x
x=18
According to this, the answer is that you and your friends washed 18 cars.

At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was
9°F greater than the temperature at 7:00 a.m. and had fallen 4°F from the
temperature at noon.
Which of the following can be used to determine the
temperature at noon in degrees Fahrenheit?
A) -3 + 9 + 4
B) -3 + 9 + (-4)
C) -3 + (-9) + 4
D) -3+ (-9) + (-4)
Answer:
A) -3 + 9 + 4
Step-by-step explanation:
We are given the following information: At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was 9°F greater than the temperature at 7:00 a.m. This means the temperature at 6:00 p.m. is calculated as -3 + 9.
We know this last temperature is 4°F less than the temperature at noon, thus the temperature at noon is calculated as -3 + 9 + 4
A) -3 + 9 + 4

Answer:
KM=40
Step-by-step explanation:
The ratio of KP/PK is equal to the ratio of LK/LM (due to the Intercept Theorem)
10/40=KL/32
you can simplify 10/40 as 1/4
so
1/4=KL/32
32=4KL
8=KL
Yet, the question asks for KM, which is KL+LM (Via Parts Whole Postulate)
Since LM is given as 32, KM is 8+32=40.

Answer:
The customer will pay $19
Option B is correct.
Step-by-step explanation:
Price of Ham per pound = $5.99
Price of Turkey per pound = $4.99
Price of Roast beef per pound = $6.99
Price of Salami per pound = $2.99
Price of Bologna per pound = $3.99
Customer purchased:
Ham = [tex]\frac{1}{4}[/tex] pound
Turkey = [tex]1\frac{1}{2}=\frac{3}{2}[/tex] pound
Roast beef = 1 pound
Bologna = [tex]\frac{3}{4}[/tex] pound
We will multiply the pound purchased with per pound price and add them to find the total cost.
The customer will pay :
[tex]\frac{1}{4}\times5.99+\frac{3}{2} \times4.99+1\times6.99+\frac{3}{4}\times3.99[/tex]
[tex]=1.4975+7.485+6.99+2.9925\\=18.965\\\approx19[/tex]
So, the customer will pay $19
Option B is correct.
Brooklyn and her friends went into a grocery store and they want to buy some apples and peaches. Each apple costs $1.75 and each peach costs $1.00. How much would it cost to buy 5 apples and 3 peaches? How much would it cost to buy xx apples and yy peaches?
Answer:
A. $11.75
B. $1.75x + $1.00y = c (cost)
Step-by-step explanation:
A. Because apples cost $1.75 each you could multiply the amount of apples you intent to buy by $1.75 which in this case the amount of apples wanted is 3. $1.75 x 5 = $8.75. You would do the same thing for the peaches except the amount per peach is different. $1.00 x 3 = $3. Then you would add the two amounts together to get the amount Brooklyn and her friend would have to pay. $8.75 + $3 = 11.75
B. Because you multiply the amount of items you intend to get by the cost per item the equation you would follow if the amount of items changed would be. $1.75x + $1.00y = c (cost)
Hope this helps!

Full Question :
A local college student will be randomly selected to attend a leadership conference in Washington, D.C. There are 2060 local college students, of which 40% are male. 520 of the college students are graduate students, and half of the graduate students are female. Which of the following best represents the probability that the selected college student will be a male student or a graduate student?
A)48 percent B) 52 percent C) 42 percent D)56 percent
Answer and Explanation:
Total local college students = 2060
40% of local college students male = 0.40×2060 = 824
College students who are graduates =
520
College students who are male graduates=520-260(half of college graduates are female)=260
Probability= number of favorable outcomes/total number of outcomes
Probability of selecting a male student or a graduate student
= probability of selecting a male student + probability of selecting a graduate student
= 820/2060+260/2060
=1080/2060
= 54/103 = 0.5242
Probability is approximately = 52%

3(2x+1)+4=10 solve for x
Step-by-step explanation:
Let's solve your equation step-by-step.
3(2x+1)+4=10
Step 1: Simplify both sides of the equation.
3(2x+1)+4=10
(3)(2x)+(3)(1)+4=10(Distribute)
6x+3+4=10
(6x)+(3+4)=10(Combine Like Terms)
6x+7=10
6x+7=10
Step 2: Subtract 7 from both sides.
6x+7−7=10−7
6x=3
Step 3: Divide both sides by 6.
6x/6=3/6
x=1/2
Answer:
x=1/2
Answer:
x = 1/2
Step-by-step explanation:
3(2x + 1) + 4 = 10
open the parenthesis
3 * 2x + 3 * 1 + 4 = 10
6x + 3 +4 = 10
6x + 7 = 10
subtract 7 from both sides of the equation
6x + 7 - 7 = 10 - 7
6x = 10 - 7
6x = 3
divide both sides of the equation by 6
6x/6 = 3/6
x = 3/6
simplify the fraction
x = 1/2

Nine runners are entered in a 100-meter dash for which a gold, silver, and bronze medal will be awarded for first, second, and third place finishes, respectively. In how many possible ways can the medals be awarded?
Answer:
504
Step-by-step explanation
9 people can get first x 8 runners left to win second x 7 who can still get third
There are 504 possible ways, the medals be awarded.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given Nine runners are entered in a 100-meter dash for which a gold, silver, and bronze medal will be awarded for first, second, and third place finishes, respectively.
The first position can be taken by any of the 9 runners
Now, the second position can be taken by remaining 8 runners
while the third position can be taken by the renaming 7 runners.
Therefore the number of ways in which these medals can be awarded;
= 9 x 8 x 7 = 504 ways
There are 504 possible ways, the medals be awarded.

Ben went to a flower shop and saw that 12 roses cost $18.96. To determine

why this proportion is incorrect. Then, write and solve a correct
proportion. *

18.96
5
Answer:
18.96 / 12 = 1.58
1.58 = the cost of 1 rose
1.58 X 5 = $7.9
Answer:
12 roses/18.86
12/18.96=5
this proportion is incorrect since the other side just says 5 and it needs to be in fraction form and have a variable as the numerator/denominator.
12/18.96=5/x
cross multiply
12x=18.96*5
12x=94.8

What is the distance between the points (0,0) and (6,8)?
Answer:
This distance between the two points is 10.
Step-by-step explanation:
You can use The Distance Formula. The Distance Formula is: [tex]D\sqrt{(x^2 - x^1)^2 + (y^2 - y^1)^2}[/tex] . Fill in for the x and y and you should get: [tex]D\sqrt{(6-0)^2 + (8-0)^2}[/tex] . Then do the math, and you should get: [tex]D\sqrt{(6)^2 + (8)^2}[/tex] .
Then after doing the squared, you should get: [tex]D\sqrt{36 + 64 }[/tex] . Then after added them, ( [tex]D\sqrt{100}[/tex] ) You find the square root of the answer ( 100). So that would be: 10.
So from (0,0) to (6,8), the distance from these two points is 10.
The distance between the points (0,0) and (6,8) is 10.
GivenThe distance between the points (0,0) and (6,8)
What is the formula to determine the distance between two points?
The distance between two points is determined by the following formula;
[tex]\rm Distance = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
Here, [tex]\rm x_1 = 0 , \ y_1 =0, \ x_2 = 6, \ y_2 =8[/tex]
Substitute all the values in the formula
[tex]\rm Distance = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\\\\\rm Distance = \sqrt{(6-0)^2 + (8-0)^2}\\\\\rm Distance = \sqrt{36+64}\\\\\rm Distance = \sqrt{100}\\\\\rm Distance = 10[/tex]
Hence, the distance between the points (0,0) and (6,8) is 10.
