In bottle 1/4 of chlorine solution is left in bottle.
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
Felicia pours 3/4 of a 2 1/2-liter bottle of chlorine solution into a swimming pool.
And, then she measures out 3/8 liters of the remaining solution to use to clean the pool filter.
Now,
Chlorine solution in bottle = 2 1/2 × ( 1 - 3/4 ) - 3/8
= 5 / 2 × 1/4 - 3/8
= 5 / 8 - 2 / 8
= 1 / 4
Thus, In bottle 1/4 of chlorine solution is left in bottle.

Step-by-step explanation:
because the fractions have different denominators you have to multiply the denominators together to figure out what to change them too. but instead you can just figure out what the decimal for each is. 1/3 is 0.33, and 4/5 is 0.80. all you do is add these together to get 1.13. so now all you do is add 2+1.13 to get 3.13.

A school bus has 25 seats, with 5 rows of 5 seats. 10 students from 2nd grade and 5 students from 1st grade travel on the bus. How many ways can the students be seated if the 2nd graders have to sit in the first two rows?
Answer:
(Answer in attachment, explanation below)
Step-by-step explanation:
The answer is B. 5P5 x 20P15.
This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.
Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.
Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.
No. of students from first grade = 15
No. of students from second grade = 5
There are 5 rows of seats
Each row contains 5 seats
Total seats = 25
No. of ways for second-grade students occupy the first row(i.e first 5 seats) =
Remaining seats = 20
No. of students from first grade = 15
So, No. of ways for first-grade students occupy remaining seats =
So, No. of ways for the students can be seated if all of the second-grade students occupy the first row =
So, Option B is true
Hence No. of ways for the students can be seated if all of the second-grade students occupy the first row is

Which of the following trigonometric ratios are correct?
Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.
sinA = opposite/hypotenusecosA = adjacent/hypotenusetanA = opposite/adjacentNow that we know three basic ratio. Let's check each choices!
sin50° = d/cThis choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.
sin50° = c/xThis choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.
tan50° = d/cThis choice is correct! As ratio states, tanA = opposite/adjacent.
tan50° = x/cThis choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.
cos50° = x/dThis choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.
cos50° = c/xThis choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.
Answer
tan50° = d/ccos50° = c/xQuestions can be asked through comment.
Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.

Find the area of the following triangle: 17 9 14 10 Note: Figure not to scale.
Find the exact solution to the equation. 5^(6-2x) = 25
Answer:
x = 2
Step-by-step explanation:
Note that 25 = 5² , then
[tex]5^{(6-2x)}[/tex] = 5²
Since the bases on both sides are 5 then equate the exponents
6 - 2x = 2 ( subtract 6 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2

laura has a 3-digit combination lock on her briefcase and has forgtten the combination. If she knows that the first digit is a 3, and the second digit is a prime, how many numbers must Laura try before the lock is sure to open?
Answer:
Laura needs to try 36 more times before the lock is sure to open.
Step-by-step explanation:
Alright, with a three digit lock, there are 9 possible numbers for each digit:
1, 2, 3, 4, 5, 6, 7, 8, and 9.
Since the first one is 3, lets move onto the second digit, which is prime.
Of the numbers between 1-9,
2, 3, 5, and 7 are prime.
With the last digit, it can be any number 1-9.
With all of this, there are 4 combos left for the second digit then 9 combos for the third digit. Therefore, there would be 36 possible combinations as 4 * 9 =36.

The figure above shows a store’s supply-demand graph for coffee makers. If the store sells $375 worth of coffee makers, which of the following is a valid possible price for them? a. $15 b. $25 c. $40 d. $55
The price of $25 is a valid possible price for coffee makers
What is a supply demand graph?A supply demand graph is a graph that shows the relationship between the supply and the demand of an item
The worth of the coffee is given as:
Worth = $375
The valid price of the coffee is calculated using:
Price = Worth/n
Where n represents the number of unit coffee
Make n the subject.
So, we have:
n = Worth/Price
This gives
n = 375/Price
When Price = 15, we have:
n = 375/15 = 25
When Price = 25, we have:
n = 375/25 = 15
When Price = 40, we have:
n = 375/40 = 9.375
When Price = 55, we have:
n = 375/55 = 6.818
Ignore the decimal results
So, we have
n = 375/15 = 25
n = 375/25 = 15
At a price of $25, the coffee maker sells less coffee than at a price of $15.
This means that they sell less to earn more
Hence, the price of $25 is a valid possible price for them

What is the total cost of buying 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts?. The price of nails is $1.30/lb, the price of washers is $0.80/lb, and the price of bolts is $2.50/lb.
Answer: $13.30
Step-by-step explanation:
price of nails = $1.30/lb
price of washers = $0.80/lb
price of bolts = $2.50/lb
The total cost of buying 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts will be:
= (2 × $1.30) + (4 × $0.80) + (3 × $2.50)
= $2.60 + $3.20 + $7.50
= $13.30
The total cost is $13.30

Answer: w = 2
Explanation: To find the slope of a line, we use the formula y = mx + b, where m is the slope and b is the y-intercept. Since there is a variable, w, we can use this formula: m = 7 + w.
We know that m, or the slope of the line, is 9. If we substitute the value of 9 into that equation... we should get 9 = 7 + w.
It's simple mathematics from here.
7 plus what is 9?? 2. That's your answer. If you need help with slope-intercept and rate of change WITHOUT variables (besides x and y, of course), feel free to let me know!!
Where did I get that 7?
Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
We will be using this formula: y - y₂ = m(x - x₁)
This equation is useful when we know:
one complete coordinate point (x₁, y₁)and the slope of the line (m)and we want to find the other point.
(x₁, y₁) is the known point. In our example, it's (-7,-7).
(x, y), sometimes written as (x₂,y₂), is (-6, w) and represents the missing coordinate.
EXAMPLE (SEE IMAGE):
slope (m) = 3
y − y1 = m(x − x1)
We know m, and also know that (x1, y1) = (3,2), and so we have:
y − 2 = 3(x − 3)
That is a perfectly good answer, but we can simplify it a little:
y − 2 = 3x − 9
y = 3x − 9 + 2
y = 3x − 7
