I NEED HELP PLEASE : A shelf has different sizes of bottles of laundry detergent. This line plot shows the number of cups of laundry detergent in each bottle. Eric buys the kind of detergent that has the most bottles. He uses 18 cup for every load of laundry he does.


How many loads of laundry can Eric do with his bottle of laundry detergent?

Answer:

2y+8+9x

Step-by-step explanation:

2(y+4)+3(x+2x)

times 2 into y and 4 and times 3 into x and  2x

2y+8+3x+6x

add both 3x and 6x x

2y+8+9x

Answer:

D

Step-by-step explanation:

rate of change of function b = (9-1)÷2=4

Step-by-step explanation:

The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!

Answer:

C is the correct answer

Hope this helped you, sorry I don't have an explanation.

Answer:

Since J = 3, K = 6, and M = 12, the equation means:

(3 • 6) + (4 • 12 ÷ 2) = ???

Step-by-step explanation:

This is because when variables are next to each other and we know what they are equal to, it is the same as saying 3 • 6. So, when two variables are next to each other, they are being multiplied. Same with 4m/2. / can also mean division. And since 4 is next to m, the two are being multiplied. All together, the answer to this equation is 42. Hope this helped!

Answer:

(3*6) +((4*12)/2)

Step-by-step explanation:

j=3 k=6 M=12

two variables next to each other is multiplication

and use order of operations (PEMDAS)

42 is the answer

Answer:

4.9y² + 2y + 4.7

Distributive property

Step-by-step explanation:

[tex]3.9y^2+5.8+4y-1.1-2y+y^2[/tex]

collect and combine like terms:

[tex]\implies 4.9y^2 +2y+4.7[/tex]

Distributive property

The distributive property states that an expression which is given in form of A (B + C) can be solved as A x (B + C) = AB + AC.  Similarly, A (B - C) can be solved as A x (B - C) = AB - AC

Answer: c

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

covert all to fractions

3*5 to get 15 and then add 2 to get 17/5

5*5 to get 25 and then add 1 to get 26/5

2*5 to get 10 and then add 4 to get 14/5

remember your signs and get

17/5 + 26/5 - 14/5

Answer:

Not completely sure about A but I know the rest!

Explanation:

a) burritos are the independent variable because it is labeled as x. X will always be the independent variable. The reason I am confused is because all throughout my learning I was told "time" will always be independent and it had always proved to be true. I would just go with burritos though.

b) linear function is y=0.75x, with 0.75 being the slope representing the amount of time taken to make x amount of burritos. I see you already did most of the work! You just have to remember that to find slope (or m), that you do change in y/change in x.

c) when graphing, draw a point at the origin, (0,0). Then count 0.75 units up, and move 1 unit to the right. Your line should be from left to right going "upward".

d) your answer for d is correct

Answer:

240cm²

Step-by-step explanation:

area of a triangle:

½ x b x h

= ½ x 6 x 4

= 3 x 4

= 12.

since there are 8 of the same triangles, they will all have the same area. so to work out the total area of a triangles, we times the area of one triangle by the 8 triangles in the polygon.

12 x 8 = 96.

for the square in the middle:

area of a square = length x width

area of a square = 12 x 12 = 144.

all we need to do is add these two totals together.

144 + 96 =240cm².

we use the units cm², because we have been multiplying xcm x ycm which can be simplified to cm² :)

Answer:

2.5

Step-by-step explanation:

If you multiply 3 by 2.5, you get 7.5. I'm assuming the number 3 is the original and the 7.5 is the result? If so, this answer is definitely correct. Hope that helps :)

Structure of Mathematical Systems Mathematics can be divided into four major areas- higher arithmetic, algebra, geometry, and analysis.

Answer:

Sorry I didn't get the answer option first

Step-by-step explanation:

higher arithmetic, algebra, geometry, and analysis.

Arithmetic: It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations- addition, subtraction, multiplication, and division, between them.

Algebra: It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented by letters of the English alphabet such as X, Y, A, B, etc. or symbols. The use of letters helps us to generalize the formulas and rules and also helps you find the unknown missing values in the algebraic expressions and equations.

Geometry: It is the most practical branch of mathematics that deals with shapes and sizes of figures and their properties. The basic elements of geometry are points, lines, angles, surfaces and solids.

There are some other branches of mathematics that you would deal with in the higher classes.

Trigonometry: Derived from two Greek terms, i.e., trigon (means a triangle) and metron (means measurement), it is the study of relationships between angles and sides of triangles.

Analysis: It is the branch that deals with the study of the rate of change in different quantities. Calculus forms the base of analysis.

Answer:

1) y = -1/2x - 1

2) y = -1

3) y = -2/4

4) y = 5/2 - 3

Step-by-step explanation:

1)

use rise (up or down) over run (left or right)

the rise is -1

the run is 2

therefore, the slope is -1/2

the y intercept is -1 (y intercept is when it touches the Y line)

y = -1/2x - 1

2)

y = -1

3)

y = -2/4

4)

y = 5/2 - 3

Answer:

5y × 5y × 5y

Step-by-step explanation:

Answer:1)  Gallons per minute change is -2/3 gallons per minute  since it decreases by 2 gallons in 3 minutes

2)  we have 5 gallons and lose 2/3 gallons per minute

(2/3 gal/minute)(x minutes) = 5 gallons

x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3)  There were 10 gallons when the tank is full

    That is 3 gallons more than the 7 gals there when Jada arrived.

    (2/3)(x) = 3

    x = 3(3/2) = 9/2 = 4 1/2 minutes

The tank was full 4 1/2 minutes before Jada arrived.

Answer:

1.

2.

Using the example of- 1, 2, 2, 3, 3, 3, 4, 5, 6, 7

Mean- Average, (the sum of every value)/10(# of values)= 3.2

Median- 3 (even though there are 2 3s, but add them up and divide the sum by 2)

Mode- 3

3. Well... you could use these data to do science reports etc, ofc in the world of academics, you would need to use this kind of statistics terms a lot. In normal life, you might have to compare the price of similar products and see which is the best to purchase, seeing the value of the median of the entire set of data.
