riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand. what is the ratio of her right hand to her left hand dribbling rate?
Answer:
5:3.
Step-by-step explanation:
Riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand.
Rate of her right hand is : [tex]\dfrac{50}{(1/2)}=100\ \text{per minute}[/tex]
Rate of her left hand is : [tex]\dfrac{30}{(1/2)}=60\ \text{per minute}[/tex]
Ratio of her right hand to her left hand dribbling rate : [tex]\dfrac{100}{60}=\dfrac{5}{3}[/tex]
So, the required ratio is 5:3.

Answer:
(2x + 5)
Step-by-step explanation:
2(x + 1) + 6x = 4(2x + 5) + 2
2x + 2 + 6x = 8x + 20 + 2
8x + 2 = 8x + 22
Because both sides are 8x it will have no solution

Which measure results in the highest value for the data given?
26, 29, 29, 17, 33, 24, 32, 24, 21, 29
mean
range
median
mode
Answer:
Mode
Step-by-step explanation:
29 occurs 3 times
Step-by-step explanation:
MEAN
add up all the numbers, then divide by how many numbers there are.
26+29+29+17+33+24+32+24+21+29/10
264/10
132/10 or 26.4
RANGE
The Range is the difference between the lowest and highest values.
lowest value: 17
highest value: 33
33-17= 16
MEDIAN
Arrange your number in numerical order:
17, 21, 24, 26, 29, 29, 29, 32, 33
Count how many numbers you have: 10
Since it's an even number divide 10 by 2: 5
Go to the number in that position and average it with the number in the next higher position to get the median.
5th position: 26
6th position: 29
26+29/ 2= 27.5
Therefore, the median is 27.5
MODE
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
17, 21, 24, 24, 26, 29, 29, 29, 32, 33
Therefore, thee mode is 29
Jamar used his Chase credit card to purchase groceries for $25.87, gas for $ 42.25, and a video game for $52.24 this month. How much should his payment to his credit card company be in order for him to avoid interest charges on these purchases?
Answer:
$120.36
Step-by-step explanation:
The computation of the amount that should be pay to his credit card is as follows;
= Purchase of groceries + gas charges + video game
= $25.87 + $42.25 + $52.24
= $120.36
He has to pay the above amount to his credit card company to avoid the interest charges on these purchases
A student takes a mathematics test scores of 52 and 64. What score on a third test will give the student an average of 60?\
Answer: 64
Step-by-step explanation:
To score an average of 60 in the three tests, the total score of the test should be: = 60 × 3 = 180
Since the student already has scores of 52 and 64, the score in the third test will be:
= 180 - (52 + 64)
= 180 - 116
= 64

2. Was your plan in part B an example of direct variation (the plan depended only on the time spent talking) or a partial variation? (the plan depended on the time spent talking and an initial cost). 3. Which Plan best for you? Was this the same as your hypothesis? 4. Which plan had the highest rate of change? Which plan has the lowest slope? 5. Using your graph, which plan would be best if you talked for 200 minutes? 6. When is the Rogers My5 plan better than the Telus prepaid plan? 7. Which plans are an example of direct variation? 8. Come up with at least 3 other things that need to be considered when choosing your cell phone plan (aside from cost per minute talking), and explain why these are important to you.

Answer:
2. not direct variation; is "partial variation"
3. Public Mobile
4. highest: Telus (prepaid); lowest: Public Mobile
5. Public Mobile
6. > 200 minutes
7. Plans 1, 2, 3 (with b=0) are direct variation
Step-by-step explanation:

__
2. The "Part B" plan chosen has a y-intercept (b) of 24, so is not direct variation. Here, that qualifies it as "partial variation."
__
3. The lowest rate by far for 600 minutes is offered by Public Mobile (plan 6). That is the same as our hypothesis.
__
4. The highest rate of change (m) is that for Plan 3, Telus (prepaid). Its cost of $0.35 per minute is higher than that for any other plan.
The plan with the lowest slope (m) is Plan 6, Public Mobile, which has zero slope.
__
5. A graph of all the plans is shown in the attachment. For any time over 140 minutes, Plan 6, Public Mobile, is the lowest cost.
__
6. On the graph, the purple line (Rodgers MY5) plan becomes lower cost for more than 200 minutes. Below that time, the green line (Telus prepaid) is lower cost.
__
7. Plans 1, 2, 3 have no cost for zero minutes, so they are all examples of direct variation.

The function f is defined by f(x )=150÷x −z , where z is constant.Find z if the value of f at x = 1 5 is equal to 250.
Answer:
-150
Step-by-step explanation:
The function f is defined by f(x )=150÷x −z , where z is constant. Find z if the value of f at x = 1 5 is equal to 250.
Given the function;
f(x )=150÷x −z
This can also be written as;
f(x )=150/x −z
If f(1.5) = 250, hence;
at x = 1.5, f(x) = 250
Substitute;
250 = 150/1.5 - z
250 = 100 - z
z = 100 - 250
z = -150
Hence the value of z is -150

Susan, Deon, and Felipe sent a total of 160 text messages during the weekend. Felipe sent 4 times as many messages as Susan. Deon sent 10 more messages than Susan. How many messages did they each send
Answer:
Susan sent 25 messages
Felipe sent 100 messages
Deon sent 35 messages
Step-by-step explanation:
160 = x + 4x + x + 10
160 = 6x + 10
6x = 150
x = 25
Sushil is 6 years older than Brian. Caroline is 5 years younger than Brian. If the total of their ages is 64, how old is the youngest of them
Answer:
16 years old
Step-by-step explanation:
Let's use the letters s, b, and c for Sushil, Brian, and Caroline's ages. Sushil is the oldest, followed by Brian, and then Caroline, the youngest. From the problem description, we can set up three equations:
s = b + 6 (Sushil is 6 years older than Brian)
c = b - 5 (Caroline is 5 years younger than Brian)
s + b + c = 64 (The total of their ages is 64)
Since s and c are already in terms of b, we can substitute them into the last equation and solve to find Brian's age:
(b + 6) + b + (b - 5) = 64
3b + 1 = 64
3b = 63
b = 21
Now that we know Brian's age, we can simply subtract 5 to find Caroline's:
c = b - 5 = 21 - 5 = 16 years old.
two years ago a man was six times as old as his daughter. In 18 years he will be twice as old as her, determine their present ages
Step-by-step explanation:
Let m = man's age right now
d = daughter's age right now
m-2 = 6(d-2) => m = 6d -12 +2 = 6d-10
m+18 = 2(d+18) => m = 2d+36-18 = 2d+18
6d-10 = 2d+18
4d = 28
d = 7
m = 32
