Answer:
48 ounces
Step-by-step explanation:
Let the amount in small container be x and that of largest be y
If a small container of detergent holds 75% as much as the large container of detergent, this can be represented as;
x = 75% of y
Given x = 36
36 = 75% of y
36 = 0.75y
y = 36/0.75
y = 48 ounces
Hence the large container will hold 48 ounces

Minnie is making tea. She knows that her tea tastes best if she lets her tea bag sit in the hot water for exactly fifteen minutes. However, depending how hot the water is, she may have to leave her tea bag in the water for 2 minutes more or less than usual. Write and solve an absolute value equation to describe this situation
Answer:
|x - 2| = 15 ; |x + 2| = 15
Step-by-step explanation:
Given that:
Wait time = 15 minutes
Variation in wait time depending on level of hotness = 2 minutes
X ± 2 = 15
x + 2 = 15 or x - 2 = 15
x = 15 - 2 = 13 or x = 15 + 2 = 17
Hence, to express the above as an absolute value equation :
|x - variation| = mean time
|x - 2| = 15 ; |x + 2| = 15

4x² + 6x = 10
Move 10 to the other side so we can factor the trinomial:
4x² + 6x - 10 = 0
Factor the GCF, or 2 out of the equation:
2(2x² + 3x - 5) = 0
Factor the terms inside of the parenthesis:
2(2x + 5)(x - 1) = 0
Disregard the coefficient of 2 and set each factor equal to 0:
2x + 5 = 0
2x = -5
x = -5/2
x - 1 = 0
x = 1
The values of x are -5/2 and 1.

The rectangular floor of a classroom is 36 feet in length and 24 feet in width. A scale drawing of the floor has a length of 12 inches. What is the perimeter, in inches, of the floor in the scale drawing?
Answer:
40 in
Step-by-step explanation:
36/12=3
24/3=8
12+12+8+8=40
The perimeter of the floor in the scale drawing is 40 inches.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
If the rectangular floor of the classroom has a length of 36 feet and a width of 24 feet, then the perimeter of the floor can be calculated as:
P = 2L + 2W
P = 2(36) + 2(24)
P = 72 + 48
P = 120 feet
We are given that the scale drawing of the floor has a length of 12 inches. This means that 12 inches on the scale drawing represent 36 feet in real life.
To find the perimeter in inches on the scale drawing, we can use the following proportion:
12 inches / 36 feet
= x inches / 120 feet
Simplifying this proportion, we get:
x = (12 inches / 36 feet) x 120 feet
x = 40 inches
Therefore,
The perimeter of the floor in the scale drawing is 40 inches.

If 20miles is 1/2 inches how and there is 3.125 inches how many miles
Answer:
3.125 inches would result in 122 miles.
Step-by-step explanation:
We can figure this out using proportions.
[tex] \frac{20 \: miles}{ \frac{1}{2} \: inches} = \frac{x}{3.125 \: inches} \\ \\ \frac{ \frac{1}{2}x }{ \frac{1}{2} } = \frac{62.5}{ \frac{1}{2} } \\ \\ x = 122[/tex]
122 miles would be the answer.
Answer:
125 miles
Step-by-step explanation:
[tex]\frac{20}{\frac{1}{2}}=\frac{x}{3.125}\\x=40 \times 3.125=125 \\x=125~miles[/tex]

Why you shouldn't worry about a credit score
Answer:Without a good credit score and history, the experts say, it's more difficult to qualify for a mortgage or car loan – and more expensive, too, because you won't get the best interest rates. In many states, bad credit can even raise your insurance premiums, cost you a rental apartment, or make it harder to get hired.

Examine the system of equations. y = 4x + 8, y = 4x – 1 Which statements best describe the two expressions? Check all that apply. They have different slopes. They have different y-intercepts. The substitution method results in the false statement, 8 = –1. The solution is (8, –1). There is no solution.
Answer:
The correct statements are as follows;
1. They have different y-intercepts
2. The substitution method results in false statement 8 = -1
3. There is no solution
Step-by-step explanation:
Here, we want to select the statement that best describes the equations
The equation for a straight line is generally;
y = mx + b
m is slope and b is the y-intercept
slope of both is same ; 4
So first assertion is wrong
they have different y-intercepts
First y-intercept is 8, second is -1
This is correct
The third statement is correct too
if we equated both y;
4x + 8 = 4x -1
We shall have 4x canceled out and left with 8 = -1
(8,-1) is not a solution
There is no solution is correct because after substituting, we have 8 = -1 which is not correct and also impossible

Tanya is at a fair and has $30 to spend on x number of rides and y number of games. Each ride is $2 and each game is $3. The equation 2x+3y=30 represents this scenario. If Tanya does not play any games, how many rides can she go on?
Answer:
15 rides
Step-by-step explanation:
From the above Question we know that if Tanya goes on a ride, the Algebraic expression = 2x
Where x = number of rides
If Tanya does not play any games, how many rides can she go on?
Note that: Tanya has $30 to spend
This question is solved:
2x = $30
x = $30/2
x = 15 rides
Hence, if Tanya does not play any games she can go on 15 rides

A plumber charges a flat fee of $50 plus an additional $20 per hour.
a) Write and equation in slope-intercept form to represent the total cost the plumber will charge
b) How much will it cost for the plumber to work for 4 hours
c) how many hours must the plumber work to obtain $180?
Answer:
a) cost = 50 + 20x, where x is the number of hours worked for.
plot cost on the y-axis and hours on the x-axis.
b) cost = 50 + 20 x 4 = $130
c) 180 = 50 + 20x
130 = 20x
6.5 = x
additional charges increment every hour, so the plumber must work for 7 hours before they obtain $180.

A yathc is anchored 90 feet offshore from the base of a lighthouse. The angle of elevation from the boat to the top of the lighthouse is 26 degrees. What is nearest to the hieght of the lighthouse
Answer:

The set up will give a right angled triangle where;
Base of the triangle = 90 ft (distance of the offshore from the base of the house)
theta = 26 degrees (angle of elevation)
Height of the house will be the opposite side = x
Using the TOA trig identity;
tan 26 = opp/hyp
tan 26 x/90
x = 90tan 26

y = 14x + 10
Step-by-step explanation:
We are given two points, (x, y) = {(5, 80), (3, 52)}. The 2-point form of the equation for a line can be used to find the equation.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (52 -80)/(3 -5)(x -5) +80 . . . . . fill in the given values
