Jerimiah records lap times at the track meet on Saturday. He records a time of 85 seconds for Jennifer's lap, but she really completed the lap in 84.25 seconds.
What is the approximate percentage of error in Jerimiah's measure?
Answer:
I'm not sure. What I would do, though, is find the difference of the two times and then find the percentage of that within the original time. So the difference is .75. So the percentage would be .25%. Just an educated guess.

Calculate the cost for the fuel needed for Sam to drive to Nanaimo to tofino
(15 points)
Answer:
cost of Sam of fuel from Nanaimo to Tofino(207km) is $34.78
Step-by-step explanation:
Diatance from Nanaimo to Tofino is 207km.
Now:
fuel consume in 100km= 12L
fuel consume in 1km=12/100L
We have to find consumption of fuel in 207km.
fuel consume in 207km=12/100 × 207km
= 24.84L
Price of 1 liter= $1.40
Price of 24.84 liters=$1.40 × 24.84
=$34.78

What is the solution to this system of equations?
Please help!!
Answer:
(5,1)
If you use substitution it'll be very easy.
In this case substitute the second equation into the first so you get y+4+y=6. Then simplify and you'll get 2y=2. Then solve for y and you'll get 1. Now plug in the 1 for y into either of the equations. Let's plug it into the second equation. X=1+4. X=5.
Final answer is (5,1).
The solution to the system of equations is x = 5, y = 1
The given system of equations is:
x + y = 6......(1)
x = y + 4......(2)
Substitute the equation x = y + 4 into the equation x + y = 6
y + 4 + y = 6
Collect like terms
y + y = 6 - 4
2y = 2
y = 2/2
y = 1
Substitute y = 1 into equation (2)
x = 1 + 4
x = 5
The solution to the system of equations is x = 5, y = 1

there are 60 teams attend a chess tournament. every team will play with every other team exactly once. Supposed each team has a 50% chances of winning any games it plays and no ties occue which is the probability that no two teams win the same number of games
The probability that no two teams win the same number of games, P ≈ 2.084 × 10⁻⁴⁵³
The reason for arriving at the above probability is as follows:
The given parameters are;
The number of teams in the tournament, n = 60
The chance of a team winning a game = 50% = 0.5
The number of ties = No ties
The required parameter:
The probability that no two teams win the same number of games
Method:
Calculate the number of ways no two teams win the same number of games, and divide the result by the total number of possible outcomes
Solution:
The number of matches played, n = [tex]\dbinom {60} {2}[/tex] = 1,770
The possible outcomes = 2; Winning or losing
The total number of possible outcomes, [tex]n_p[/tex] = 2¹⁷⁷⁰
The number of games won by each team is between 0 and 59
The ways in which no two teams won the same number of games is given by the games won by the teams to be 0, 1, 2,..., 57, 58, 59
Therefore, the number of ways no two teams won the same number of games, the required outcomes, [tex]n_k[/tex] = 59!
[tex]Probability = \dfrac{Number \ of \ possible \ outcomes}{Number \ of \ required\ outcomes}[/tex]
The probability that no two teams win the same number of games is given as follows;
[tex]\mathbf{P(No \ two \ teams \ won \ the \ same \ number \ of \ games)} = \dfrac{n_k}{n_p}[/tex]
Therefore;
[tex]P(No \ two \ teams \ won \ the \ same \ number \ of \ games) = \dfrac{59!}{2^{1,770}} \approx \mathbf{2.084 \times 10^{-453}}[/tex]

using the variable n write an algebraic expression for a number increased by 6
The answer you are looking for is simply just n+6.
Solution/Explanation:
If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:
n+6.
And, also, increase obviously means the same thing as adding.
So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.
So, therefore, the final answer is n+6.

Marley made three full pitchers of lemonade. Eachpitcher holds exactly five cups of liquid. How many ounces of lemonade did Marley make?
Answer:
120 fluid ounces
Step-by-step explanation:
1 cup = 8 fluid oz
Multiply 15 on both sides (since there is 3 pitchers and each is 5 cups, so 3 * 5 = 15 cups in total for all 3 pitchers) and we get 15 cups = 120 fluid oz.
So that's our answer

Step-by-step explanation:
First you divide the number of clicks by seconds.
36÷5=7.2
26÷3=8.6
Now you know how much clicks the bots do in 1 second
Bot#3= 7.2
Bot#4= 8.6
Now multiply by 10.
Bot#3= 72
Bot#4= 86
Bot#4 does more clicks in 10 seconds.
18. Mabel gave Margo a bag containing red, white, and
blue marbles. The bag contained half as many red
marbles as blue ones, and 1/4 of the marbles in the
bag were white. If 8 of the marbles were red, how
many marbles were in the bag?
Answer:
32.
Step-by-step explanation:
Let the number of red marbles be x then the number of blue = 2x
So we have 8 red and 16 blue marbles.
If the total number of marbles are y marbles the number of white one = y/4.
So y = y/4 + 8 + 16
3/4y = 24
y = 24 * 4/3
= 96/3
= 32 marbles.

A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7
A.1188
B.1200
C.1220
D.1224
Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²

The distance between A and B is:
3^2 + 1^2 = c^2
9 + 1 = c^2
c = 10^1/2
The distance between B and C is:
1^2 + 3^2 = c^2
1 + 9 = c^2
c = 10^1/2
The distance between C and A is:
4^2 + 2^2 = c^2
16 + 4 = c^2
c= 20^1/2
Since AB and BC are the same, but AC isn't, the triangle is isosceles.
