Answer: $0.33 per cup

Step-by-step explanation:

15.84/3 to find the price per 1 gallon.

15.84/3 = 5.28 per gallon

There are 16 cups in a gallon, so divide the price of a single gallon by 16.

5.28/16 = price per cup

5.28/16 = .33

The price for each cup of bleach is $0.33.

Answer:

277g / 40cm³

Step-by-step explanation:

Density = mass / volume

In this case:

volume = 8cm*5cm*4cm = 160cm³

then:

Density = 1088g / 160cm³ = 544g/80cm³ = 277g/40cm³

Answer: 39 ounces of strawberry juice, 78 ounces of water.

Step-by-step explanation:

Since Molly uses "each ounce" meaning 1 per strawberry juice, 39 ounces of strawberry infused water would mean she uses 39 ounces of strawberry juice. Then, it says she uses two times as many as those 39 ounces of strawberry juice for water. This means you multiply 39 by 2 which means you get 78 ounces.

Molly uses 39 ounces of strawberry juice and 78 ounces of water to get 39 ounces of Strawberry Infused Water.

The lowest form of this fraction 49/100 is still 49/100.

It should be noted that a fraction can only be reduced to its lowest term if it has a common factor.

In this case, there is no common factor between 49 and 100.

Therefore, the lowest form of this fraction 49/100 is still 49/100

Here are the examples that combine to make zero:

Two month ago, the temperature was 15 degrees. This morning, the temperature dropped to 15 degrees below zero.

Michael has $0 in his account. He makes a purchase of $75. Later in the day, he deposits 75 in the account.

An elevator rises to the ninth floor and she then takes the elevator from the ninth floor to the ground floor.

The parking garage is located 4 floors below ground level. But, her office is 4 floors above ground level.

What are the real world examples?

In order for the examples to combine to make zero, there has to be a positive number and a negative number. A positive number is a number that is greater than zero. A negative number is a number that is less than zero.

In order for the positive and negative number to make zero, they have to be added together. Addition is determining the total value or summing two or more numbers. Addition is one of the four basic operations in mathematics.

The value of the function f(-4) = 16.

A function is categorized as a relationship between a set of inputs that each have one output.

For the given function in the question;

f(x) = x ² , if  x < 0.

f(x) = 0 , if  x = 0.

f(x) = 2x + 1 , if  x > 0

Now, estimate the values;

(a) f(-4)

As, the value of the x to be substitute is negative, the function used will be.

f(x) = x ² ,for  x < 0.

Put the value x = -4

f(-4) = (-4)²

f(-4) = 16

The value of f(-4) = 16.

(b) f(0)

As the value of function is zero.

Then,

f(x) = 0 , if  x = 0.

Put x = 0 in function we will get.

f(x) = 0.

(c) f(2)

As the value to be substituted is positive, the function used is;

f(x) = 2x + 1 , if  x > 0

Put x = 2

f(2) = 4 + 1

f(2) = 5

Thus, the value of f(2) is 5.

The representation of 1 / 8 in decimal form will be 0.125 and it is a rational number as it is a terminating decimal.

We are given a fraction:

1 / 8.

We have to represent it as a decimal and tell that it is a rational number.

To write it as a decimal, First we will make the denominator a multiple of 10:

1 / 8 × 125 / 125 = 125 / 1000.

Now writing it in the decimal form, we get that:

= 0.125.

Now, we can see that it is a non repeating terminating number.

So, we can say that it is a rational number.

Therefore, the representation of 1 / 8 in decimal form will be 0.125 and it is a rational number as it is a terminating decimal.

Step-by-step explanation:

The triangle ΔXYZ is congruent to the triangle ΔX'Y'Z'. And the intersection of ZZ' and AB form a right angle.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.

The reflection does not change the shape and size of the geometry. But flipped the image.

The triangle ΔXYZ is reflected across the line AB to get the tringle ΔX'Y'Z'.

The diagram is given below.

A reflection is a transformation that maps every point P over a line such that the line segment PP' will intersects the line of reflection at a right angle.

Thus, the triangle ΔXYZ is congruent to the triangle ΔX'Y'Z'. And the intersection of ZZ' and AB form a right angle.

The graph of the linear equation can be seen in the image below.

Here we have the linear equation:

y = -4x + 8

And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.

if x = 0 then:

y = -4*0 + 8 = 8

So we have the ordered pair (0, 8).

if x = 1 then:

y = -4*1 + 8 = 4

Then we have the ordered pair (1, 4)

If x = 2 then:

y = -4*2 + 8 = 0

Then we have the ordered pair (2, 0).

Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.

That is the graph of our linear equation:

Answer:

the answer will be

-2

Answer: an equation of the line in slope-intercept form (y=mx+b) is

y = -2x - 8

Answer:

a.  y + 3 = 0

Step-by-step explanation:

x-axis has slope of 0 so any lines parallel to x-axis has slope of 0

With m = 0 , x = -4, y = -3

y = mx + b

-3 = (0)(-4) + b

b = -3

so y = -3

or y + 3 = 0

Answer:  Choice 2

invalid. The inner circle is plants, and the outer circle is those with cells.

=========================================================

Further Explanation:

If we throw a dart at random, and we land in the inner circle (plants), then we automatically land in the outer circle (has cells).

Now imagine the dart landed in the "has cells" circle, but outside the smaller circle. This could be stuff like animal cells, bacteria, etc. So just because something has cells it does not automatically make it a plant. Saying "an iris has cells" is not enough info to be able to tell it's a plant or not. This means the conclusion of "irises are plants" is shaky at best.

This is why the overall argument structure is invalid.

the distance between Point A (-8,-2) and Point B(6,-1) in Radical form= [tex]\sqrt{197}[/tex]

Distance formula:
The distance between two points formula uses the coordinates of two points in space. In coordinate geometry, the distance between two points can be calculated using the distance formula, present in a two-dimensional or three-dimensional space. The distance formula for two points is also an application of the Pythagoras theorem

the distance formula is used to find the distance between any two points when we already know the coordinates. The points could be present alone on the x-axis or y-axis or on both axes.

Let us consider, that there are two points say A and B in an XY plane. The coordinates of point A are (x1,y1), and of B are (x2,y2). Then the formula to find the distance between two points PQ is given by:

AB=[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]

Note: If the coordinates of two points P and Q are such that, (x1, 0) and (x2, 0), the distance between PQ will be given by:

PQ = |x2 – x1|

the distance between point origin O(0,0) and P(x,y) is given by:

OP = √((x2 – 0)² + (y2 – 0)²)

OP = √((x2)² + (y2)²)

or simply,

OP = √(x² + y²)

Solution :

where x and y are coordinates of points other than the origin.

Given :

(x1,y1) = (-8,-2)

(x2,y2)= (6,-1)

Solution:

[tex]d=\sqrt{x^{2} +y^{2} } \\d=\sqrt{(6+8)^{2} +(-1+2)^{2} } \\d=\sqrt{14^{2}+1^{2} } \\[/tex]

[tex]d=\sqrt({197)[/tex]

Radical form= [tex]\sqrt{197}[/tex]
