Answers
Answer:
A = 81 - 20.25π
P = 36 - 9π
Step-by-step explanation:
To find the perimeter and area of the highlighted shapes, we must find those of the square and full circle. Then subtract the circle's area from the square. Do the same for perimeter.

1. If the trapezoid represents 1 whole, what do each of the following shapes represent? Be prepared to show or explain your reasoning.
1. 1 triangle
2. 1 rhombus
3. 1 hexagon
only question 1
Answers
Answer:
Part(A): 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.
Part(B): 1 rhombus represents [tex]\dfrac{2}{3}[/tex] of whole.
Part(C): 1 hexagon represents 2 whole.
Step-by-step explanation:
Consider the provided figure.
Here, it is given that the trapezoid represents 1 whole.
Part 1. Consider figure 1.
3 triangles can be group into a whole trapezoid.
[tex]3\times \frac{1}{3}=1[/tex]
Hence, 1 triangle represents [tex]\dfrac{1}{3}[/tex] of whole.
Part 2.
Consider figure 2.
Here, in figure 2 if we put 1 rhombus on the given trapezoid, we will be left with the shape is a triangle, which is [tex]\dfrac{1}{3}[/tex] of the trapezoid. Also, the triangle is [tex]\dfrac{1}{2}[/tex] of the rhombus.
We know that 3 triangles can be fit into 1 trapezoid and 2 triangles can be fit on a rhombus
Hence, 1 rhombus represents [tex]\dfrac{2}{3}[/tex] of whole.
Part 3.
Consider figure 3.
2 trapezoid = 1 hexagon
Hence, 1 hexagon represents 2 whole.

slope=4/3 y-intercept=-5
Answers
Answer: 4/3 - 5
I assume you want to know the numbers in slope intercept form so... yeah
Step-by-step explanation
Answer:
The equation of the line in point-slope form is:
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]
The graph is also attached below.
Step-by-step explanation:
Given
Slope m = 4/3y-intercept = -5We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
As we are given the y-intercept = -5
Thus, the point (0, -5) represents the y-intercept.
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case,
m = 4/3(x₁, y₁) = (0, -5)substituting m = 4/3 and the point (0, -5) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y\:-\:\left(-5\right)\:=\:\frac{4}{3}\:\left(x\:-\:0\right)[/tex]
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]
Therefore, the equation of the line in point-slope form is:
[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]
The graph is also attached below.

Step-by-step explanation:
The required, the triangle changes size, but not shape. Option A is correct.
Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.
Here,
A dilation to place triangle ABC on top of triangle DE is the triangle changes size, but not shape. Because it is necessary property of dilation. Since dilation only helps to scale the figure. In the question it is mention that shifting of triangle through dilation there is why triangle must be scale to shift over one another

Original price is $56. Discount is 25%. what is the sales price
Answers
Answer:
Sale Price = $42 (answer). This means the cost of the item to you is $42. You will pay $42 for a item with original price of $56 when discounted 25%. In this example, if you buy an item at $56 with 25% discount, you will pay 56 - 14 = 42 dollars.
Step-by-step explanation:
Answer:
$42
Step-by-step explanation:
The original price is $56.
The discount is 25% off.
To solve the equation, turn 25 into a decimal. The you multiply it by 56.
25 to a decimal = 0.25
56 * 0.25 = 14
The answer is 14. That means the thing that is being bought is $14 off.
So, you have to subtract 56 and 14.
56 - 14 = 42

Step-by-step explanation:
6.25 litter is essentially
6250 ml
And 6250>625
Answer:
Yes
Step-by-step explanation:
First we need to know that
1 L = 1000 ml
Using that, we can see that 6.25 L = 6250 ml
(6.25 x 1000, multiply by 1000 to convert from L to ml)
Therefore, 6.25 L (or 6250 ml) is bigger than 625 ml.
If n(U) = 125, n(A) = 80, n(B) = 65,
then, greatest value of n(AUB) is

Answer:
650,000
Step-by-step explanation:
Given these numbers in the question, multiply all three numbers to get your final answer which is 650,000.
The greatest value of n(AUB) is "145".
An component as well as substance or entity that belongs to both A and B would be included throughout the Union. A union is denoted by "U".Given:
→ n(U) = 125
→ n(A) = 80
→ n(B) = 65
As we know,
The formula is:
⇒ [tex]n(A \cup B)_{max} = n(A)+n(B)[/tex]
By substituting the given values of n(A) and n(B), we get

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 8/9.
There are 63 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Answers
If the probability of picking a red marble out of the total 63 is 8/9, then it's reasonable to think that 8/9 of the total number of marbles must be red. So there are likely 8/9 × 63 = 56 red marbles in the bag.
