Answer:
$8/hour
Step-by-step explanation:
We will start by finding how much money she made before spending it. The amount of money she took home added to how much money she spent will give us this. ([tex]12 + 36 = 48[/tex]). This means she made $48 before spending it.
Now we can solve for her wage. Let [tex]x[/tex] be her hourly wage
(the 6 is the number of hours she worked, this multiplied by her wage should give us 48)
[tex]6x = 48\\x = 8[/tex]
This means that she made $8/hour.
That is the answer

36. During rehearsal for the Founders' Day choir
program, the director, Mrs. Mazurek, tried 3 different
configurations, each using all the choir members at the
rehearsal. One configuration was to have only rows of
12, one was to have only rows of 15, and one was to
have only rows of 20. None of these configurations
worked because for each, the last row had 1 person
less than the other rows. What was the least of the
possible numbers of choir members at the rehearsal?
The LCM stands for the least common multiple. The least of the possible number of choir members at the rehearsal is 59.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
Given the configurations of choir members at the rehearsal, which are,
One configuration was to have only rows of 12, One was to have only rows of 15, And one was to have only rows of 20.Now, it takes the LCM of 12, 15, and 20, then the LCM will be 60, But since None of these configurations worked because for each, the last row had 1 person less than the other rows. The number of members was 1 less than the LCM.
Hence, the least of the possible number of choir members at the rehearsal is 59.

Algebra 2 pls help!!! why do you only reflect one “side” of a parabola when defining its inverse?
This is why because
Parabola is symmetric on both sides of vertexThe x coordinate of vertex is the axis of symmetry for parabola.So reflection of only one side helps us in shifting the domain and range to its inversewyatt has a square garden. he adds 3 feet to one side and 1 foot to the other and now it is a rectangle with an area of ft^2 what are the new dimensions of the garden
Answer:
The new dimensions are 6 ft and 4 ft.
Step-by-step explanation:
Let x = side of original square.
The sides are increased by 3 ft and 1 ft, so the new side lengths of the rectangle are
x + 3 and x + 1
The area of the rectangle is length × width.
area = (x + 3)(x + 1)
area = x² + 4x + 3
The area is 24 ft².
x² + 4x + 3 = 24
x² + 4x - 21 = 0
(x + 7)(x - 3) = 0
x + 7 = 0 or x - 3 = 0
x = -7 or x = 3
x + 3 = 3 + 3 = 6
x + 1 = 3 + 1 = 4
The new dimensions are 6 ft and 4 ft.
Solve for x.

Write an equation and find how much longer it would take to fly against the wind than
with it between New York and Los Angeles if the wind speed increases to 150 miles per
hour and the airspeed of the jet is 525 miles per hour. Round to the nearest hundredth.
The time taken by the jet will be equal to 6.58 hours.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that:-
Assume that the distance between New York and Los Angeles is 2468 miles.The speed of wind is 150 miles per hour.The speed of the jet is 525 miles per hour.The time taken by the jet will be calculated as:-
Average speed = 525 - 150 = 375 miles per hour.
The time is taken to cover the distance of 2468 miles will be:-
Time = 2468 / 375 = 6.58 hours.
Therefore time taken by the jet will be equal to 6.58 hours.

At the grocery store, apples are one price and chocolate bars are another. mary buys three apples and one chocolate bar for $2.70. bill buys one apple and 4 chocolate bars for $6.40. write a system of equations to model mary's and bill's purchases and then determine the cost of a chocolate bar.
Answer:
Step-by-step explanation:
Step 1 is to collect the information in a table format. The attached Table1 summarizes what we know in columns 1 - 3. Columns 4 - 6 show the data we're about to calculate, so ignore them for the moment.
.I use A for the price of one apple and C for the price of 1 chocolate bar. We know how many of each are purchased by both Mary and Bill, and the total each paid.
The last column (6) shows the price for each, which comes from the derivation presented below.
We can set the information in columns 1 - 3 into equations:
Mary: 3A+1C = 2.70 [This states that Mary bought 3 apples at a price of A for each apple, and 1 chocolate bar at a price of C per bar.]
Bill: 1A + 4C = 6.40 [In the same fashion, this summarizes how Bill parted with his $6.40]
---
Now let's rearrange either equation to solve for C. I'll use Mary's equation:
3A+1C = 2.70
1C = 2.70 - 3A
This tells us that the price of 1 chocolate bar is $2.70 minus the cost of 3 apples. Interesting, but we need the price of a chocolate bar to determine an exact amount.
----
Now take Bill's equation and substitute the value we just derived for the price of a chocolate bar C = (2.70-3A).
1A + 4C = 6.40
1A + 4(2.70 - 3A) = 6.40
1A + 10.80 - 12A = 6.40
-11A = -4.40
A = 0.40 This is the price for 1 apple. This is the value in the last column (6) of attached Table1.
---
Now we can use the value of $0.40 in either equation to find the price of a chocolate bar. I'll use the rearranged equation we developed for Mary:
1C = 2.70 - 3A
1C = 2.70 - 3(0.40) [A = 0.40 from the above work]
1C = 2.70 - 1.20
1C = 1.50
The price of 1 chocolate bar is $1.50. Pricey, and bad for health. But very tasty.
Columns 4 and 5 are the total costs for the apples and bars bought by each, and their sums add up to the amounts we were given at the start of the problem. So our prices must be correct.

The product of 9 and 7 is 63. In other words, the result of multiplying 9 and 7 is 63.
To find the result of multiplying 9 and 7, by follow a step-by-step process.
First, start by writing the multiplication expression as 9 multiplied by 7.
Next, multiply the digit in the ones place of the first number (9) with the digit in the ones place of the second number (7).
In this case, 9 multiplied by 7 equals 63.
Then, move to the tens place of the second number (7) and multiply it with the digit in the ones place of the first number (9).
Since there is no digit in the tens place of the first number, skip this step.
Finally, add the products obtained from the previous steps.
In this case, there is only one product, which is 63.
Therefore, the result of multiplying 9 and 7 is 63.
Multiplication is a fundamental arithmetic operation used to determine the total value when a number is repeated a certain number of times. In this case, multiplying 9 by 7 represents adding nine 7s together.
