Lin runs 5 laps around a track in 8 minutes. If Lin runs 21 laps at
the same rate, how long does it take her?
a) 13.13 minutes
b) 441 minutes
c) 33,6 minutes
d) 1.6 minutes
Answer:
It will take 25.2 minutes to complete 21 laps.
Step-by-step explanation:
The rate of covering 5 laps is:
v = 6/5
Therefore, the time taken to cover 21 laps is:
t = 21/v
t = 21*6/5
t = 25.2
Hence, it will take 25.2 minutes or 25 minutes 12 seconds for Lin to complete 21 laps.

. There are seven people in a club: A, B, C, D, E, F, and G. A committee of 3 people is formed. What is the probability that G is on the committee
Step-by-step explanation:
there are 7 over 4 total possibilities to create a group of 3 or if 7.
that is
7! / (4! × (7-4)!) = 7×6×5 / 3×2 = 7×5 = 35
for the probability we need also the number of the desired cases, a the probability is
number of desired cases / number of total cases
the desired cases are all combinations, where G is a part of.
for that we make G a constant, and now we have only 6 variable candidates for the other 2 positions on the committee.
that is 6 over 2 or
6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15
so, the probability that G is in the committee is
15/35 = 3/7 = 0.428571429...
SOLVE PLEASEEE (FOR 20 POINTS)
for a ratonal, the expression only makes sense if the denominator is not 0, since if that occurs then the expression becomes undefined, a division by 0 is always undefined, for this case, when does that occur? Let's set the denominator to 0 and solve for "x".
[tex]\cfrac{\sqrt{2}}{\sqrt{x-1}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{setting the denominator to 0}}{\sqrt{x-1}=0\implies (\sqrt{x-1})^2=0^2}\implies x-1=0\implies x=1[/tex]
well then, let's see what happens when x = 1
[tex]\cfrac{\sqrt{2}}{\sqrt{x-1}}\implies \cfrac{\sqrt{2(1)}}{\sqrt{1-1}}\implies \cfrac{\sqrt{2}}{\sqrt{0}}\implies \cfrac{\sqrt{2}}{0}\leftarrow und efined[/tex]
so the only values that makes sense is anything but x < 1, because a smaller value of 1 will give us an imaginary value from the root, so the only values that makes sense are namely { x | x ∈ ℝ; x > 1 }

Hello my name is Galaxy and I will be helping you today! I hope you are having a nice day!
We can solve this in two steps, one being Algebra and the second being Answer/Checking our answer. I'll start off with Algebra.
Algebra
We can start to solve this problem by using Algebra and simplifying it down. We can also use the distributive property to solve the problem by using the proof it shows. The distributive property states that we can multiply whats inside the paranthesis by the number on the outside and get the same answer.
We can prove it by doing this:
[tex]2(1+4)=(2*1)+(2*4)?\\2+8=2+8?\\10=10[/tex]
Now that we have the tools we need to begin solving.
Solving
We can start to solve it by simplifying the equation from its distributive state. We can do that by doing the following:
[tex]-3(x-2)=12\\-3x+6=12\\[/tex]
Now that we've simplified, we can begin solving it.
[tex]-3x+6=12\\-3x=12-6\\-3x=6\\x=6 \div -3\\x=-2[/tex]
We have gotten our answer of x being -2. We can now double check our answers.
[tex]-3(-2-2)=12?\\(-3*-2)+(-3*-2)=12?\\6+6=12?\\12=12[/tex]
Remember that if we multiply two negatives it is a positive!
Cheers!

Write the equation of the parabola in vertex form. The vertex is (−3, −4) and the parabola passes through the point (−1, 0).
Start with vertex form.
y = a(x − h)2 + k
Using the vertex (−3, −4), substitute h = –3 and k = −4.
y = a(x − (−3))2 + (−4)
y = a(x + 3)2 + (−4)
Substitute the included point (−1, 0) into the equation for x and y.
0 = a(−1 + 3)2 − 4
Simplify the equation to solve for a.
0 = a(2)2 − 4
Type your answer and then click or tap Done.

Step-by-step explanation:
There is a total of 1350 students in the school
One day, 81 of the 1350 students are absent
Work out the percentage of the students who are absent
The percentage of the students who are absent when 81 of the 1350 students are absent is 6%.
What is Percentage?Percentage in simple words can be defined as a part per hundred.
In other words, it is the ratio which can be defined as a fraction of 100. It is usually denoted by the symbol %.
Percentage can also be said as dimensionless number as it does not have any dimensions.
Percentage of a number can be calculated by dividing the number with the whole part and then multiplying by 100.
Total number of students in the school = 1350
Number of students absent = 81
Here we have to calculate the percentage of 81 out of 1350.
Percentage of the students who are absent = [tex]\frac{81}{1350}[/tex] × 100 = 6%
Hence 6% of the students are absent that day.

Estimate 81 x 38 (giving brainliest to first person to answer)
Answer: 3200
Step-by-step explanation:
The rounding rule:
The ones digits : + From 1 to 4 we round down
+ From 5 to 9 we round up
So we have 81 rounds to 80 and 38 rounds to 40.
We have 80 * 40 = 3200.

a) Determine the functions whose graphs are parallel to the graph of the function y=0.5x+10 and intersect the graph of the function y= -1.5x. The functions are expressed by the formulas.
y = -1.5x + 6, y = 0.5x-6
b) Determine the functions whose graphs are parallel to the graph of the function y=0.5x+10 and intersect the graph of the function y= -1.5x. The functions are expressed by the formulas.
y = 0.5x+4, y = 0.5x, y = 3+1.5x
a) The function that is parallel to the function [tex]y = 0.5\cdot x + 10[/tex] and intercept the function [tex]y = -1.5\cdot x[/tex] is [tex]y = 0.5\cdot x - 6[/tex].

Consider the system of equations:
-2x + Ky = 26
13x - 6у = -7
Find all values of k for which the system has exactly one solution. Choose "does not exist" if such a k does not exist.
Answer:
Step-by-step explanation:
First of all, if the system of equations has exactly one solution, then the graph of these two equations will intersect at exactly one point, which means their slopes will be different. If the slopes are the same, there could be infinitely many solutions or no solution.
Rearrange the first equation to solve for slope of [tex]-2x+ky=26[/tex]
y = (2/k)x + 26/k
The slope is 2/k.
The slope of the second equation is 13/6
as long as 2/k does not equal to 13/6, we have exactly one solution.
SO, the last step:
[tex]\dfrac{2}{k} \neq \dfrac{13}{6}\\[/tex]
[tex]k \neq \dfrac{2}{\dfrac{13}{6}}[/tex]
[tex]k\neq \dfrac{12}{13}[/tex]

Then she spent half of her remaining money on a new dress. Then she spent $11 taking herself and her friend out to lunch. Then she spent one-third of her remaining money on a book. On her way home she bought gas for $12 and spent one-fourth of her remaining money on a discount CD at the convenience store.
