Following are the fractions in decimal form.

A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line.

It is calculated by dividing the total number of parts by the number of equal parts that were counted (numerator) (denominator). Proper fractions, improper fractions, mixed fractions, like fractions, unit fractions, equivalent fractions, and same numerator fractions are the seven different types of fractions.

a) 15 / 32 = 0.46875

b) 21/64 = 0.328125

c) 9/16 = 0.5625

Answer:

6.75m^2

Step-by-step explanation:

The shape is made up of a trapezoid on top and a rectangle on the bottom.

The rectangle's area is easier, so first:

Area_rectangle

= length × width

= 2.5 × .5

= 1.25 m^2

For area of a trapezoid, you need three measures: both bases and the height.

One base is 3m. The other base is the top side of the rectangle, so it is 2.5m.

The height is

2.5 - .5

because the height of the trapezoid is not including the rectangle, so take away .5

Trapezoid's height is 2.5 - .5 is 2.

Area_trapezoid

= 1/2 (base+base)height

= 1/2 (3+2.5)2

=5.5

Area_total

= Trapezoid+rectangle

= 5.5 + 1.25

=6.75m^2

The total area is 6.75square meters.

Answer:

Area = 6.75 meter square.

The equation of a line in point-slope form is y - 5 = 3( x - 1).

Equation of a line in slope intercept form is y = mx + b, where slope = m and y-intercept = b.The slope of a line is defined as the rate of change of the y-axis with respect to the x-axis.

We know the equation of a line in point-slope form is y - y₁ = m(x - x₁).

Given P = (x,y) and Q = (1,5) or (x₁, y₁).

∴ Equation of a line in point-slope form given (x₁,y₁) = (1,5) and slope(m) = 3 is y - 5 = 3( x - 1).

1 cup =

Here, 1 cup carton of milk is $0.28

ii) 2-quart carton of milk = $3.76​

Given that 1 quart = 4 cups

2 quart = 4 * 2 = 8 cups

Thus

1 cup =

Here, a cup carton of milk is $0.47

$0.28 is less than $0.47, therefore the better buy would be 2-cup carton of milk for $0.56.

Therefore, the best buy would be 2-cup carton of milk for $0.56, because it is cheaper.

Options 3 and 4 are empty sets.

Well-defined collection of objects or elements is called sets in mathematics. Set having no elements is known as empty set.

We can also define finite and infinite sets  based on the number of elements in a set. An empty set is denoted by the symbol '∅' and is read as 'phi'.

Given U = {x|x is a positive integer greater than 1},

It is not an empty set ,if the set has elements such that x is prime or 2x is prime( positive integer greater than 1).

As the elements in the option 3 and 4 are fractions, therefore they are  empty set as integers don't include fractions or decimals. Integer, also known as whole number, is any positive or negative number in which decimal parts or fractions is not included.

Sarah practiced 7/20 of an hour more than Eloise

Given

Eloise did practice 2/5 of an hour

Sarah practiced for 3/4 of an hour

total time spent by Eloise = 2/5 x 60

                                           = 24 minutes

Total time spent by  Sarah = 3/4 x 60

Answer:

3x + 8y = - 8

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

8x - 3y = - 4 ( subtract 8x from both sides )

- 3y = - 8x - 4 ( divide through by - 3 )

y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{4}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{8}{3}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{8}{3} }[/tex] = - [tex]\frac{3}{8}[/tex] , then

y = - [tex]\frac{3}{8}[/tex] x + c ← is the partial equation of the perpendicular line

to find c substitute (- 8, 2 ) into the partial equation

2 = 3 + c ⇒ c = 2 - 3 = - 1

y = - [tex]\frac{3}{8}[/tex] x - 1 ← equation of perpendicular line in slope- intercept form

multiply through by 8 to clear the fraction

8y = - 3x - 8 ( add 3x to both sides )

3x + 8y = - 8 ← equation of perpendicular line in standard form

Answer: w=1.28

Step-by-step explanation:

swap the sides of the equation

The transformation of the graph y = (x - 2)² to the graph of y=x²-3 is 2 units left and 3 units down therefore, option (B) is correct.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

As per the given graph  y = (x - 2)²

A function will shift a unit left for x → x + a and b units down if y → y -  b.

Replace x → x + 2 and y → y - 3

y = (x + 2 - 2)² -  3

y = x² - 3

Can you write it in lines instead of like that, I can answer if you do that.

The greatest number of bags that can be filled using all the candy is 9.

The greatest number of bags that can be filled using all the candy can be determined by calculating the greatest common factor (GCF).

The greatest common factor of two or more numbers is a term used in mathematics that can be described as the greatest number among all the common factors of these numbers. If x and y are two numbers, GCF is the largest number that divides both x and y without leaving any remainder.

As there are 36 chocolate bars and 81 caramel bars, therefore we determine the GCF of 36 and 81;

The common factors of 36 and 81 are found to be: 1, 3 and 9

Hence the greatest common factor (GCF) out of these is 9.

Therefore the greatest number of bags that can be filled using all the candy is calculated to be 9

The size of the tank would be suggested to hold 40 small fish is 48 gallons. (Solved using ratios)

What is a ratio?

A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of fruit contains seven apples and six lemons, the apple-to-lemon ratio is seven to six. Similarly, the proportion of lemons to oranges is 6:7, while the proportion of oranges to overall fruit is 8:14. (or 4:7). A ratio can be defined by providing both constituent integers, which are written as "a to b" or "a:b," or by providing only the value of their quotient a/b. Equal quotients result in equal ratios. A and B are frequently referred to as ratio words, with A being the antecedent and B being the consequent.
