9. A team of 8 basketball players need to choose a co-captain and captain.
A) combination
B) permutation
C) neither
Answer:
b
Step-by-step explanation:
Since the order is important, as there are different roles, a permutation is used, hence option B is correct.
When to use the combination and the permutation formula?If the order in which the options are taken is important, permutation is used.Otherwise, if the order in which the options are taken is not important, combination is used.In this problem:
If the order is LeBron and Giannis, LeBron is the co-captain and Giannis is the captain.If it is Giannis and LeBron, Giannis is the co-captain and LeBron is the captain.Hence the order is important, which means that it is a permutation.

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is 30 for 5 soft tacos and 2 burritos. How much do soft tacos cost? 3x+2y=25 4x+2y=30 X-soft tacos y-burritos
Answer:
Step-by-step explanation:
Let the cost of one soft taco = s
Let the cost of one burrito = b
So we have this system
3s + 3b = 11.25
4s + 2b = 10.00 (1)
Divide the first equation through by 3 and we have that
s + b = 3.75 subtract b from both sides
s = 3.75 - b (2)
Sub (2) into (1) and we have
4 (3.75 - b) + 2b = 10.00 simplify
15 - 4b + 2b = 10.00
-2b + 15 =10.00 subtract 15 from both sides
-2b = - 5.00 divide both sides by -2
b = 2.50
And using (2)
s = 3.75 - 2.50 = 1.50
So... a soft taco 1.50 and a burrito is 2.50

URGENTT!! Susan will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60 per mile driven. The second plan has an initial fee of $75 and costs an additional $0.10 per mile driven. How many miles would Susan need to drive for the two plans to cost the same?
Answer:
150 miles
Step-by-step explanation:
Let
x = number of miles
Plan A: 0.60x
Plan B: 75 + 0.10x
How many miles would Susan need to drive for the two plans to cost the same?
0.60x =75 + 0.10x
0.60x - 0.10x = 75
0.50x =75
x = 75/0.50
x = 150 miles
Susan needs to drive for 150 miles for the two plans to cost the same

12. Solomon scored 88% on his math test. If the test had 25 questions total, how many
questions did Solomon miss?
Answer:
He missed 3 questions (which is a score of 22/25 that equals 88%)
Step-by-step explanation:
This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.
So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.
Hope it helps.
Ben finds 4 + 11 using a number line. He counts 11 on from 4. Which is a faster way to solve this problem
Step-by-step explanation:
The way to solve the problem would be just add the two number as 11+4 =15.
This would avoid the tedious process first drawing the number line and then counting each number to reach the same answer, which could be easily reached by just adding the two numbers.

A new car is for lease for $750 per month with a down payment of $1,898. What is the cost for 42 months for this vehicle?
$79,716
$33,398
$80,466
$31,500
Answer:
33,398
Step-by-step explanation:
So first you have to do 750x42 and that gets you 31,500 but then you have to pay the down payment so then it is 31,500+1,898 which gets you 33,398.
The fishbowl is shaped like a sphere the fishbowl has a diameter of 16 what is the closest value of water in the Fishbowl and cubic inches
Answer:
2144.66 cubic inches
Step-by-step explanation:
The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.
What is the closest value of water in the Fishbowl in cubic inches?
From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.
This means we are to find the volume.
The volume of a sphere is given as:
4/3πr³
We are given Diameter of the fish bowl = 16 inches
Radius = Diameter/2 = 16 inches/2
= 8 inches
Hence,
Volume of the sphere (Volume of water) = 4/3 × π × 8³
= 2144.66 cubic inches

A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Answer:
1,050 years
Step-by-step explanation:
A comet passes Earth every 70 years.
Another comet passes Earth
every 75 years
If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Find the lowest common multiple of 70 years and 75 years
70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,
75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350
Lowest common multiple of 70 years and 75 years is 1,050 years
Therefore,
If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

What is the end behavior of the function f(x) = 2* + 5?
Answer:o understand the behaviour of a polynomial graphically all one one needs is the degree (order) and leading coefficient. This two components predict what polynomial does graphically as gets larger or smaller indefinitely. This called "end behavior". For example it easy to predict what a polynomial with even degree and +ve leading coefficient will do. All even polynomial have both ends of the graph moving in the same direction with direction dictated by the sign of leading coefficient. On the other hand odd power will get have the polynomial end points moving in opposite direction, with the leading coefficient dictating the direction.

Step-by-step explanation:
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
