Answer:
The chlorine tablets are $36 and the pH test kit is $4.40.
Step-by-step explanation:
So what I first did was add 90+11 (because $90 for the chlorine tablets and $11 for the pH kit). The answer you should get is 101. From their I did 101 multiplied by 40% or 101 multiplied by .40 (40% and 0.40 are the same thing). You now get $40.4.
Now I did 90·40%. I got $36
Then I did 11·40%. I got 4.4
I added them up and got $40.4 which was my new price so now we know that the chlorine tablets are $36 and the pH test kit is $4.40.

jessica made $234 for 13 hours of work. At the same rate, how many hours would she have to work to make $162?
Answer: 9 hours
We would get:
1 hour of work = $18
162 divided by 18 = 9
So she would have to work 9 hours
Answer:
9 hours
Step-by-step explanation:
Step One: A rate is the same thing as ratio. This just means that there is a proportion. For example, for every 3 dogs, there are 4 cats. This would mean that for 6 dogs there are 8 cats, and so on.
Step Two: Okay, because these numbers are larger, it is easiest to scale it back to one. The proportion or rate given is $234/13 hours. We would divide by 13 to get it to 1: $18/1 hour. The proportion is usually a decimal, but these numbers happen to divide nicely.
Step Three: Now, we can do 162/18 to see what the scale is, or how much times larger it is: 162/18=9.
Step Four: Lastly, just do 1 times 9, which tells it is 9 hours. To check the work, make sure 9 is less than the original proportion; it should take less time to make less money. 9 is less than 13, so this is the answer!

Answer:
B
Step-by-step explanation:
Given
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
solution is x = 3, x = 6 → B

Which graph represents the function f(x)=−2^x−1?
Answer:
The graph in the bottom right corner
Write the inequality shown by the graph.
Answer: A
Step-by-step explanation:
The line and dots are closed circle, so B and D would not be the answer.
The line have passed through the point (-6,4) and (0,2); we uses to find the slope.
slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3
we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.
y = -1/3x + 2

A ship sails 9 km due West, then 5 km due South.
Find the bearing of the ship from its initial position.
Give your answer correct to 2 decimal places.
Answer:
10.29 km
Step-by-step explanation:
Given that,
A ship sails 9 km due West, then 5 km due South.
We need to find the distance of the ship from its initial position. Let the distance be d. We can find it as follows :
[tex]d=\sqrt{9^2+5^2} \\\\d=10.29\ km[/tex]
So, the required distance of the ship from its initial position is equal to 10.29 km.
simplify each of the following.

Alexa is saving to buy a new bike that costs $265. So far she has saved $45. If she is able to save $11 each week, how many weeks will it take her to save enough to buy her coveted bike? Kole wrote (265 - 45)/11 = w. Bella wrote 11w + 45 = 265. Who do you agree with? Justify your response.
Answer: Bella is correct.
Step-by-step explanation:
Let the number of weeks will it take her to save enough to buy her coveted bike be represented by w.
The information given in the question can then be formed into an equation as:
45 + 11(w) = 265
45 + 11w = 265
Collect like terms
11w = 265 - 45
11w = 220
w = 220/11
w = 20
He'll save for 20 weeks
Bella is correct.

On Saturday, a local hamburger shop sold a combined total of 261 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Saturday?
Answer:
134 hamburgers
Step-by-step explanation:
Let H = # of hamburgers
# of cheeseburgers = 2H
H + 2H = 402
3H = 402
H = 402/3
H = 134
A local grocery store stocks packages of plain M&M's and packages of peanut M&M's. The ratio of the number of packages of peanut M&M's to the total number of packages on the shelf was 8 to 18.
Which number could be the number of packages of plain M&M's on the shelf?
Answer:
30
Step-by-step explanation: Because each batch has 18 total m&ms and there are 8 in each batch minus and then multiply.
The number of packages of plain M&M's on the shelf could be any multiples of 5.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
Ratio of the number of packages of peanut M&M's to the total number of packages on the shelf = 8 : 18
That is, if there are total of 18 packages, 8 are peanut M&M's.
Number of plain M&M's out of 18 total packages = 18 - 8 = 10.
So,
Ratio of peanut M&M's to plain M&M's = 8 : 10
= 4 : 5
This indicates that, for a constant x,
Number of peanut M&M's = 4x
Number of plain M&M's = 5x
So the number of packages of plain M&M's on the shelf could only be the multiples of 5.
So it could be 5, 10, 15, 20, 25, 30, .......
Hence the number of plain M&M's on the shelf could be 5, 10, 15, 20, 25, 30, ......
