The graph shows the number of hours that Tammy spends typing for work, x, and the amount of pay that she earns, y.
On a graph titled Tammy's Pay, number of hours is on the x-axis and pay in dollars is on the y-axis. A line goes through points (2, 18) and (8, 42).
What does the y-intercept represent?
Answer: The y-intercept is the initial amount Tammy earns.
Step-by-step explanation:
Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
7. Danielle went to the grocery store to buy pies for a family dinner. The manager told her they were having a sale in which she could get the third pie for half price if she bought the first two for full price. Is the relationship between the number of pies and the cost proportional? JUSTIFY YOUR ANSWER
Answer:
No
Step-by-step explanation:
The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.

Drag and drop one set of parentheses into the expression below so that it's value when simplified is 31. Where would these ( ) go? _2_*4^2_+_square root36_-_13_
Answer:
2 * (4^2 + squared root of 36) - 13
since the space where the _ are, that's where the parenthyeses would be placed. If you place these around 2, you get 25, is around 4^2, it's also 25, if placed around square root of 36, it will also be 25, but if placed around -13, it's -46. But place then around 4^2 + the square root of 36, then you will get your answer of 31 simplified.

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units

If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill? Enter your answer to the nearest cent.
Part B
After adding a tip, the total lunch cost was $32.24. What percentage tip did they give? Enter your answer to the nearest percentage.
pls show how you set the problem up this is due soon so pls help!
Answer:
Given : Michael and Imani go out to eat for lunch.
their food and beverages cost $25.30
8% meals tax,
After adding a tip, the total lunch cost was $32.24
To Find : how much is the bill
What percentage tip did they give?
Solution:
food and beverages cost $25.30
8% meals tax,
Tax = (8/100) 25.3 = 2.02 $
BILL = 25.30 + 2.02
= 27.32 $
BILL = 27.32 $
After adding a tip, the total lunch cost was $32.24.
=> Tip = 32.24. - 27.32 = 4.92$
% of Tip = (4.92 / 27.32) * 100 = 18 %
Tip = 18 %
Step-by-step explanation:
Answer:
Part A: $28.46
Part B: 8.5%
Step-by-step explanation:
Part A:
We know that in this equation that 25.30 is the 100% number and we need to find 8% of this.
We can then divide 8 by 25.30 which is 3.1625 but the problem asks us to "round to the nearest cent" so we then know that the 8% is $3.16 we have to then add the 8% to the total which would be: 25.30 + 3.16 which equals $28.46 which is your answer to Part A.
Part B:
After adding a tip that problem states that the total went up from $28.46 to $32.24 to find out how much they tipped we can minus these 2 totals to find the difference
32.24 - 28.46 = 3.78
We now know that they tipped $3.78 and we now need to convert this into a percentage.
Right now the whole 100% is $32.24, we then divided 32.24 by 3.78 which would be 8.5291 and so on but wo round this it would be 8.5%
The answer to Part B would be 8.5%
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

A machine cuts lumber into 8-foot planks. Company regulations allow the lengths to vary by 1/2%, which can be either an increase or decrease of 1/2% of the intended length. Find the range of the values allowed by the company's regulations.
A. How do you express 1/2% as a decimal
____ ÷ 100 = _____
B. What is the length, in feet, that the planks are allowed to vary? Remember, the · indicates multiplication.
____ · ____ = ____ foot
C. What is the length of the shortest allowable plank and the longest allowable plank cut by the machine?
Shortest: 8 - ___ = ___ feet
Longest: 8 + ___ = ___ feet
Answer:
A.
To express 1/2% as a decimal, you divide 1/2 by 100. You can use a fraction bar or a slash to indicate division. Like this:
1/2 ÷ 100 = 0.005
or
1/2 / 100 = 0.005
B.
To find the length that the planks are allowed to vary, you multiply the decimal value of 1/2% by the intended length of 8 feet. Like this:
0.005 · 8 = 0.04 foot
C.
To find the shortest and longest allowable planks, you subtract and add the variation length from and to the intended length of 8 feet. Like this:
Shortest: 8 - 0.04 = 7.96 feet
Longest: 8 + 0.04 = 8.04 feet

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
