What is greater 2 1/8 or 2 2/15

Answer:

[tex]Rate = 8640 fl\ oz/hour[/tex]

Step-by-step explanation:

Given

Rate: 9 gallon in every 8 minutes

Required

Express in fluid ounces per hour

Express rate as follows;

[tex]Rate = \frac{9\ gallon}{8\ minutes}[/tex]

1 gallon = 128 fluid ounces;

So:

[tex]Rate = \frac{9 * 128 fl\ oz}{8\ minutes}[/tex]

1 minutes = 1/60 hour;

So:

[tex]Rate = \frac{9 * 128 fl\ oz}{8 * \frac{1}{60} hour}[/tex]

[tex]Rate = \frac{1152 fl\ oz}{ \frac{8}{60} hour}[/tex]

[tex]Rate = 1152\ fl\ oz/ \frac{8}{60}\ hour[/tex]

[tex]Rate = 1152* \frac{60}{8}\ fl\ oz/hour[/tex]

[tex]Rate = \frac{1152*60}{8}\ fl\ oz/hour[/tex]

[tex]Rate = \frac{69120}{8}\ fl\ oz/hour[/tex]

[tex]Rate = 8640 fl\ oz/hour[/tex]

Answer:

3ml

Step-by-step explanation:

while on a beach vacation,Tasha makes a scale drawing of point of interest between two piers.

Given that On her drawing,

2 cm represent 0.5ml.

The piers are 12cm apart on tasha's drawing.

To calculate the actual distance, in miles between the two piers, first divide the 12cm by 2 cm

12/2 = 6 cm

Multiply the answer by 0.5

6 × 0.5 = 3ml

Therefore, the actual distance, in miles between the two piers is 3ml.

Answer:

x=3/5

Step-by-step explanation:

3x+5=0

3x=-5

x=-5/3

Answer:

x = 5/3

Step-by-step explanation:

Given equation: 3x-5 = 0

Add both sides by 5, we get

= 3x - 5 + 5 = 0 + 5

= 3x = 5

Divide both sides by 3, we get

3x/3 = 5/3

or, 3x = 5

so, x = 5/3

Answer:

x = 22

Step-by-step explanation:

Let's say that a & b are complementary angles...

Then cos a = sin b

We can also write sin(3x) as ,

[tex] \sin(3x) = \cos(90 - 3x) [/tex]

Substituting the value of sin(3x) in the question ,

[tex] \cos(x + 2) = \cos(90 - 3x) [/tex]

Cancelling cos from both the sides gives us -

[tex]x + 2 = 90 - 3x\\ [/tex]

Solving this eqn , x = 22

Answer:

C

Let's simplify the answers. Use absolute value.

| -5.1 | = 5.1 - > |5.1| = 5.1

4.7 - > |4.7| = 4.7

| -0.9 | = 0.9 - > |0.9| = 0.9

- |6.7| = -6.7 - > |-6.7| = 6.7

Now, order each from least to greatest.

0.9, 4.7, 5.1, 6.7

Which one is the smallest? 0.9

So, C is correct.

Answer:

[tex]10d[/tex] dollars

Step-by-step explanation:

[tex]d[/tex] is a variable, which is just a placeholder for an unknown value. Therefore, we can treat [tex]d[/tex] as if it's a number.

If you earn a certain amount of dollars per week, and you work for 10 weeks, then to find how much money you earn, you'd multiply the amount of weeks (10) by the dollars per week right?

Same logic applies for variables.

Since we have [tex]d[/tex] acting as a placeholder for the amount earned per week, then the total amount of money earned in 10 weeks is [tex]10\cdot d[/tex], which can just be represented as [tex]10d[/tex].

Hope this helped!

Answer:

S = 1/2 . x^2 + 11/2 . x + 15

Step-by-step explanation:

- Let S = the area of the shaded region

- From the figure we see that S = 1/2 the area of the rectangle

- The area of the rectangle is (x+5)(x+6) = x^2 + 11x + 30

--> S = 1/2 (x^2 + 11x + 30)

--> S = 1/2 . x^2 + 11/2 . x + 15

Answer:

dimensions of the phone are 7 inches x 12.44 inches

Step-by-step explanation:

The formula for the aspect ratio of a display device is a proportional relationship between the width and the height of the display.

That is;

Aspect ratio = height/width

Now, we are given;

Aspect ratio = 16:9 or 16/9

Width = 7" = 177.8 mm

Thus;

16/9 = height/177.8

Multiply both sides by 177.8 to give;

Height = (16 × 177.8)/9

Height = 316.089 mm

Converting 316.089 mm to inches gives us 12.44 inches.

Thus, dimensions of the phone are 7 inches x 12.44 inches

Answer:

Nikki is 16, Travis is 8

Step-by-step explanation:

We need to set up an equation

If x is Nikki's age, then Travis' would x-8 since Nikki is 8 years older.

x+(x-8)=24

2x-8=24

2x=32

x=16

Nikki is 16, Travis is 8

Answer:

the oldest is 16 and the other sibling Travis =8

Step-by-step explanation:

x+y=24

x-y=8  ⇒ x=8+y

solve by substitute

8+y+y=24

2y=24-8

2y=16

y=16/2=8

x=8+y

x=8+8=16

x=16

y=8

Answer:

36

Step-by-step explanation:

(4+2)²

4+2=6

6²=36

Answer:

36

Step-by-step explanation:

So we have the expression:

[tex](4+2)^2[/tex]

Order of operations says: 1) Parentheses, 2) Exponents, 3) Multiplication/Division and 4) Addition/Subtraction.

So, add within the parentheses first:

[tex](4+2)^2\\=(6)^2[/tex]

Now square:

[tex]=36[/tex]

So our answer is 36.

Also, note that you apparently used the distribute property. The distribute property does not work with addition and exponents:

[tex](4+2)^2\neq4^2+2^2[/tex]

You cannot do this. This isn't correct. Instead, you must first add and then square.

Answer & Step-by-step explanation:

definition of coordinate pair

A system and method is provided for converting an input signal from a sequence of rectangular coordinate pairs to a sequence of polar coordinate pairs.

solving by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system

solving by substitution

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.

solving by elimination

The elimination method of solving systems of equations is also called the addition method. To solve a system of equations by elimination we transform the system such that one variable "cancels out". ... In order to solve for y, take the value for x and substitute it back into either one of the original equations.

slope-intercept form

the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept

standard form

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number)

term

In Algebra a term is either a single number or variable, or numbers and variables multiplied together.

Terms are separated by + or − signs, or sometimes by divide.

constant

A fixed value.

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.

variables

A symbol for a value we don't know yet. It is usually a letter like x or y.

Example: in x + 2 = 6, x is the variable.

Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.

multiplicative combination

Any of the ways we can combine things, when the order does not matter.

Example: For a fruit salad, how many different combinations of 2 ingredients can you make with apple, banana and cherry?

Answer: {apple, banana}, {apple, cherry} or {banana, cherry}

When the order does matter, such as a secret code, it is a Permutation.

Answer:

65%

Step-by-step explanation:

We're looking for how big a part of the original price the reduced price is.

This can be done using division.

E.g., if the reduced price was $1, and the original price was $10, we can find how big of a part $1 is of $10 by dividing them.

[tex]\frac{1}{10} = 0.1 = 10\%[/tex]

The reduced price is 10% of the original price. Remember that 0.1 in decimal is 10%, same as how 1.0 is 100%, and 0.3 is 30%.

Let's try this using our dresses. The reduced price was $39, and the original price was $60.

[tex]\frac{39}{60} = 0.65 = 65\%[/tex]

The dresses were sold at 65% of the original price.

Note, this does NOT mean that they were sold at a 65% discount. To find that, we'd have to find out how big the discount was. Then, we'd divide it by the original price.

For example, if the original price was $10, and the reduced price is $9, then the reduced price is 90% of the original price, but it's at a 10% discount.

[tex]\frac{9}{10} = 0.9 = 90\%[/tex]

[tex]10-9=1[/tex]

[tex]\frac{1}{10}=0.1=10\%[/tex]
