Answer:
7 miles per hour.
Step-by-step explanation:
Right now, the relationship in the problem represents 3[tex]\frac{1}{2}[/tex] miles in hours. To find out what the unit rate is (number of miles per mile), we need to multiply both sides of the equation show BeLoW:
3[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{2}[/tex]
7 miles = 1 hour
Therefore, Doug's average speed in miles per hour is 7 (7 miles per hour).

A 2 fl oz bottle of orange juice costs $8, and a 4 fl oz bottle of orange juice costs $12. Which is a better buy?
ANSWER= 4 fl oz bottle of orange juice that costs $12 is the better buy.
Answer:
yes 4fl oz bottle of orange juice that costs $12 dollars is better to buy
Step-by-step explanation:
2 bottles of orange juice=8$
if you split 8$, you get 4$ that means each bottles of orange juice is 4$
so if you get 4 bottles of orange juice it is 4$x4$= 16$ The question says that 4 bottles cost 12$ its supposed to be 16$. So the 4 fl oz bottle of orange juice that costs 12$ dollars is better to buy.
1 bottle=4$ 2x4=8$ (the first equation)
1bottle=4$ 4x4=16 (the second equation) But the question says we got the bottle of orange juice for 12$ its supposed to be 16$ that is a huge discount. so yes the answer is correct.
What is the slope of the line that passes through the points (4, 5) and (12, 7)?
Answer:
1/4
Step-by-step explanation:
To find slope, we use the formula rise over run (y2-y1 over x2-x1)
So first, our y's: 7-5=2
And our x's: 12-4=8
2/8 simplifies to 1/4
What is c?
1.51=c10
c = can someone explain I'm a little confused >
Answer:
0.151
Step-by-step explanation:
1.51=c10
we divide 10 by both sides
1.51/10 = c10/10
we cancel 10/10 and 1.51/10=0.151
so
c=0.151

Jim is having a Halloween party for 60 children. He will give each child at least one candy bar. If each bag of candy contains 12
candy bars, which inequality gives the minimum number of bags, b, Jim will need to buy?
Yes
Answer:
5 bags of candy
Step-by-step explanation:
60/12= 5
Since there are 12 pieces of candy in each bag, 12*5= 60, so each kid can have 1 piece of candy.

A computers random number generator produces random integers from 1 - 50. What is the probability that the first three integers generated for single digit numbers
Answer:
9/50
Step-by-step explanation:
There are nine single digit numbers from integers 1-50 so in order to calculate the probability of getting 3 random numbers from 1-50 to be single digits:
Probability = number of favorable outcomes /total number of outcomes
Therefore Probability of getting 3 single digits randomly from 1-50 = 9/50

A family is calculating the cost for one semester of college next year. Each hour of class will cost $155. A scholarship gift of $64 can be deducted from costs. If h is the number of hours taken, and c is the total cost, which equation can be used to calculate the total tuition costs for a semester?
C=89h
C=155h+64
C=155h-64
C=-155h-64
Answer:
c=155h-64
Step-by-step explanation:
you mulitply the cost of the classes by the amount of hours, then you deduct the scholarship gift(64) from the total and get your total cost of the semester

5z + 20 + 10 - 5z = ? combind like terms
the z cancle out leaving 20 + 10 = ?
Answer:
20z-10z
Step-by-step explanation:
Distribute the 5 to both z and 4 which would make it 20z
Distribute the 5 to the 2 and -z which gives you 10z

You and your friend are in a canoe race. Your friend is a half mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour. You are 8.5 miles from the finish line. How long will it take to catch up to your friend?
Answer:
To catch your friend you have to paddle for 1.25 hours
Step-by-step explanation:
Your friend is 0.5 mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour.
Since the speed is the relationship between the space traveled by an object and the time used for it, then the distance is defined as:
distance= speed*time
Being x the time it takes to reach your friend, then your friend's position will be:
3miles per hour*x + 0.5 (since your friend is 0.5 mile in front of you)while your position is:
3.4 miles per hour*xWhen you reach your friend the position of both should be the same. So:
3*x + 0.5= 3.4*x
Solving:
0.5= 3.4*x - 3*x
0.5= 0.4*x
0.5 ÷0.4= x
1.25= x
This means that to catch your friend you have to paddle for 1.25 hours
what two numbers' sum=-4 and product=-2
Let a and b be the two numbers. Then
a + b = -4
a b = -2
Solve the second equation for b :
b = -2/a
Substitute this into the first equation:
a - 2/a = -4
Multiply both sides by a :
a² - 2 = -4a
Move 4a to the left side:
a² + 4a - 2 = 0
Use the quadratic formula to solve for a :
a = (-4 ± √(4² - 4(-2))) / 2
a = -2 ± √6
If a = -2 + √6, then
-2 + √6 + b = -4
b = -2 - √6
In the other case, we end up with the same numbers, but a and b are swapped.

The sum of these two given quadratic function is (9x² - y² + 8xy - 1).
What is a quadratic function?A quadratic function is a function that has a variable with the highest power of the variable is 2.
A quadratic function may contain more than one variable. However, the highest degree of any variable must be 2.
Given, two function are 8x² + 12 - y² and x² - 13 + 8xy.
Therefore, the sum of these two given function are:
(8x² + 12 - y²) + (x² - 13 + 8xy)
= 8x² + x² - y² + 8xy +12 - 13
= 9x² - y² + 8xy - 1
