Answer:
12.56 m²
Step-by-step explanation:
Given,
π = 3.14
d = 4m
To find : A
Formulas : -
1 ) r = d/2
2 ) A = πr²
r = 4 / 2 = 2m
A = πr²
= 3.14 x 2²
= 3.14 x 2 x 2
A = 12.56 m²

Answers
Seen can close the lid on the cube container with a 6 in. marker inside it which has the side length of 4 inches.
What is a cube shape?The cube shape is the three-dimensional solid which has 6 equal side. The diagonal of a cube can be calculated with the following formula;
d=6∛a
Here, (a) is the length of the side of the cube.
Sean has a plastic container which is in the shape of a cube. The side lengths of the cube container is 4 in. Thus, the diagonal of the cube is,
d=6∛a
d=6∛(4)
d=6 x 1.587
d=9.522 inches.
The diagonal of the cube container is 9.522 inches, which is more than the length of the marker.
9.522 in >6 in
Hence, Seen can close the lid on the cube container with a 6 in. marker inside it, which has the side length of 4 inches.

Find the exact value of the given angle. Simply all radicals and rationalize all denominators.
Answers
Answer:
4√33/33
Step-by-step explanation:
Solution,
Here,
sinθ=4/7
p/h=4/7
b=?
Now using Pythagoras theorem,
[tex]\hookrightarrow h^{2} =p^{2} +b^{2} \\\\\hookrightarrow (7)^{2} =(4)^{2} +b^{2}\\\\\hookrightarrow 49-16=b^{2} \\\\\hookrightarrow b=\sqrt{33}[/tex]
Again,
tanθ=p/b
[tex]tan\theta=\frac{4}{\sqrt{33} } \\\\tan\theta=\frac{4}{\sqrt{33} } \times \frac{\sqrt{33} }{\sqrt{33} } \\\\tan\theta=\frac{4\sqrt{33} }{33}[/tex]
According to the question ,
Sin θ = 4/7
We know that , Sin θ = Perpendicular/Hypotenuse
So , by Pythagoras theorem
Perpendicular = 4 unitsHypotenuse = 7 units Base = let it be xHypotenuse² = Perpendicular ² + Base ²
7² = 4² + x²
49-16 = x²
√33 = x
5.7 = x
So , the base is 5.7 units (approx)
Tan θ = Perpendicular/base
Tan θ = 4/5.7

Jade buys 4 books that cost the same amount of money. she spends $50.
Part A: in the first box, enter an equation to represent the cost of each book, c, which jade buys.
Part B: in the second box, enter the cost of each book represented by c in this situation.
Answers
The equation, representing the cost of each book, c, which Jade buys is c = 50/4. The cost of each book represented by c in this situation is $12.5
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b[/tex] = a divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is so because as a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
For this case, we're given that;
Jade buys 4 booksEach book's cost is same, represented by 'c' (in dollars)Total amount spent on buying those 4 books = $504 books = $50 in cost
Dividing 4 books in 4 groups equally gives 1 book per group.
Dividing $50 in 4 groups equally, which would correspond to those 4 groups of books, would give cost per group, and therefore cost of each book.
We've got:
[tex]\text{Cost of each book} = c = \dfrac{50}{4} \: \rm (in \: dollars)[/tex]
Dividing further, we get:
[tex]c = 50/4 = 12.5 \: \rm dollars[/tex]
Thus, the equation, representing the cost of each book, c, which Jade buys is c = 50/4. The cost of each book represented by c in this situation is $12.5

This table represents a proportional relationship between x and y.

y 1.82 2.24 2.66 3.08
What is the constant of proportionality?
Enter your answer as a decimal in the box.
Answers
Reason:
Pick any column and divide y over x
column one: y/x = (1.82)/(1.3) = 1.4column two: y/x = (2.24)/(1.6) = 1.4column three: y/x = (2.66)/(1.9) = 1.4column four: y/x = (3.08)/(2.2) = 1.4You only need to pick one column when it comes to showing your work.
The constant of proportionality is 1.4

B. The measure of ZJ is 65
L

C. The measure of ZK is 89
D. The measure of ZL is 43°
8x
Answers
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.

Step-by-step explanation:
Y-intercept 5
Answer:
y- intercept = 5
Step-by-step explanation:
to find the y- intercept let x = 0 in the equation and solve for y
this relies on the fact that when the line crosses the y- axis the x- coordinate is zero, then
0 - 2y = - 10 , that is
- 2y = - 10 ( divide both sides by - 2 )
y = 5
then y- intercept = 5

What are mathematical operations?
An operation exists as a mathematical action. Addition, subtraction, multiplication, division, and calculating the root exist all instances of a mathematical operation.
Given: 4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1 or
4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1
Convert mixed fraction into a proper fraction we have

Now convert the proper form of the fraction into a decimal
[tex]$4.75 * 7.50 * 1.16 * 1.34[/tex]
Inserting operation signs, then we get
[tex]= (4.75/7.50) * 1.17 * 1.34[/tex]

Answer: 36 square units
Step-by-step explanation:
Divide the figure into 2 shapes: a rectangle and a triangle. Count the squares to find the dimensions of each figure. The rectangle has a width of 4 units and a length of 6 units. The triangle has a base of 6 units and a height of 4 units.
The formula for the area of a rectangle is length * width. The area of the rectangle is 4*6 = 24 square units.
The formula for the area of a triangle is (base * height)/2. The area of the triangle is (4*6)/2 = 24/2 = 12 square units.
Add the areas of both the rectangle and triangle. 24+12 = 36 square units.
