Answer:
11+2x= 52 , $20.50 equal one pass
Step-by-step explanation:52 is the total and $11 is included in that total. So you have part of your equation : 11 + something = 52. In order to find that " something " you have to set up a variable : 2x , 2 because that is the amount of passes bought and X because you don't know the cost of the passes yet. You now have your equation : 11+2x=52. Next you isolate the "2x" by subtracting eleven from itself and what you do to one side of the equation you have to do to the other, so you subtract 11 from 52 and are left with 41 . You then have the simplified equation : 2x=41 . Now you're going to isolate the variable by dividing 2x by 2 and doing the same to 41. You're then left with X= 20.50 , the cost of one ticket
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.

mr. salmon is getting pool ready for summer. The pool liner had some holes in it, so he decides to replace it. In order to replace the liner, the water must be drained from the pool. The pool holds 25,000 gallons of water, and it takes 8 hours to drain 80% of the water. the answer is 2 hours. Why is that the answer
Answer:
Because 8 hours to drain 80% would mean it takes 10 hours to completely drain the pool leaving the 2 hours to drain.

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.

Answer:
a. reflection across line l
b. see attached
c. no
Step-by-step explanation:
a.The easiest transformation to put figure H' back where figure H is will be "reflection across line l". A reflection back across the same line of reflection puts the figure in its original location.
__
b.The attached figure shows the requested translation and labeling. The dim dotted figure is the original translation of H along vector EF. The reflection of that across line l is marked H''' as required.
__
c.No, figures H'' and H''' are not in the same location. One only needs to look at the diagram to see this.
In general the order of translation and reflection makes a difference. This means reflection of H to H', then translation to H'' will have a different result than translation of H to H(shadow), then reflection to H'''.

Step-by-step explanation:
To find a ratio, you have to divide a next terms with before terms.
A1 = 35/2
A2 = 7
ratio = A2 ÷ A1
ratio = 7 ÷ 35/2
ratio = 7 × 2/35
ratio = 14/35 = 0,4
Ratio = 0,4
How do the expressions 7+h2−5 and 10(h+2)−2h compare when h = 9? Drag a symbol into the box to correctly complete the statement. 7+h2−5 Response area 10(h+2)−2h when h = 9.
Answer:
8+h3-4
Step-by-step explanation:
10(h+2)−2h when h = 9.
The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expressions are,
⇒ 7 + h² - 5
⇒ 10 (h + 2) - 2h
Now,
Solve the expression for h = 9 and find the relation between them as;
Since, The expressions are,
⇒ 7 + h² - 5 ...(i)
⇒ 10 (h + 2) - 2h ...(ii)
Substitute h = 9 in (i), we get;
⇒ 7 + h² - 5 = 7 + 9² - 5
= 7 + 81 - 5
= 83
And, Substitute h = 9 in (ii), we get;
⇒ 10 (h + 2) - 2h = 10 (9 + 2) - 2 x 9
= 10 x 11 - 18
= 110 - 18
= 92
Thus, We get;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h
Therefore, The relation between the expression at h = 9 will be;
⇒ 7 + h² - 5 < 10 (h + 2) - 2h

Jeremy makes $4.70 every time he mows a lawn but it costs him $6.80 to refill the tank. If Jeremy mows 5 lawns using 3 tanks of gas, how much did he profit?
Show expression used and step by step explanation
Answer:
$3.10
Step-by-step explanation:
Money earned by mowing 5 lawns (income) = $4.70 x 5 = $23.50
Cost of filling 3 tanks (expenditure) = $6.80 x 3 = $20.40
Profit = income - expenditure
= $23.50 - $20.40
= $3.10

How many pounds of chocolate that is 45% cocoa should be mixed with 6 pounds of pure cocoa mass to obtain a chocolate that is 78% cocoa? plz help im dying irl
Using a system of equation, the amount in pounds of chocolate required is 4
Let :
Number of pounds of chocolate = cHence, we can create an equation thus :
0.45c + 6(1) = 0.78(6 + c)
0.45c + 6 = 4.68 + 0.78c
Collect like terms
6 - 4.68 = 0.78c - 0.45c
1.32 = 0.33c
Divide both sides by 0.33
c = 1.32 / 0.33
c = 4
Hence, 4 pounds of chocolate is required.

. 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...

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.
