The radius of a circle is 2 inches. What is the area of a sector bounded by a 45° arc?
Answers
Answer:
Step-by-step explanation:
Area = angle / 360 * pi * r^2
angle = 45
r = 2
pi = 3.14
Area = 45 / 360 * 3.14 * 2^2
Area = 365.2 / 360
Area = 1.57 square inches.

During a sale, a shopkeeper reduced the prices of all his goods by 25%.
Calculate the normal selling price of a pair of shoes which was sold for Rs 1350 in the sale.
Answers
let be the real price x :
x - x × ( 25/100 ) = 1350
x - x × ( 1/4 ) = 1350
x - x/4 = 1350
4x - x / 4 = 1350
3x / 4 = 1350
3x = 1350 × 4
3x = 5400
x = 5400 ÷ 3
x = Rs 1800

decimal- 0.30
percent- 30%
Answer: 3/10, 0.3, 30%
Step-by-step explanation: If you count the shaded rectangles individually, you can find the numerator and denominator of the fraction. For the decimal, it would have to be 0.3 because 0.3 has "three-tenths", which is 3 in the tenths place. For the percentage, 3/10 is equal to 30/100 because 30/100 can be simplified to 3/10.

What is the first step in solving the following equation:
−1\2x − 33 = 33
Answers
Answer:
add 33 to both sides
Step-by-step explanation:
Given
- [tex]\frac{1}{2}[/tex] x - 33 = 33 ( add 33 to both sides )
- [tex]\frac{1}{2}[/tex] x = 66 ( multiply both sides by - 2 to clear the fraction )
x = - 132
Answer:
First step is to make x the subject of the equation.
Step-by-step explanation:
[tex]-\frac{1}{2} x - 33 = 33\\\\-\frac{1}{2} x= 33 + 33\\\\-\frac{1}{2} x = 66\\\\- x = 2 \times 66 = 132\\x = -132[/tex]

What are the dimensions of the tabletop with the
leaves open? Round to the nearest tenth of a foot. Someone please answer I need this for extra credit :))
Answers
Answer:
Dimensions of the tabletop is 2.8 cm × 2.8 cm.
Step-by-step explanation:
From the picture attached,
ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.
Dimensions of the tabletop ABCD,
Length = AB
Width = BC
Coordinates of A → (1, 3)
Coordinates of B → (3, 5)
Coordinates of C → (5, 3)
Coordinates of D → (3, 1)
Length of segment = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
AB = [tex]\sqrt{(3-1)^2+(5-3)^2}[/tex]
= [tex]\sqrt{4+4}[/tex]
= [tex]2\sqrt{2}[/tex]
≈ 2.8 units
BC = [tex]\sqrt{(5-3)^2+(3-5)^2}[/tex]
= [tex]\sqrt{4+4}[/tex]
= [tex]2\sqrt{2}[/tex]
= 2.8 units
Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.

Answers
Answer:
<FGH and <JKL are supplementary
<AED and <BEC are complementary
Step-by-step explanation:
For supplementary angles, the sum of the pair of angles must be 180degrees
Given;
<FGH = 109degrees
<JKL = 71degrees
Taking the sum
<FGH + <JKL
= 109 + 71
= 180
Since the sum of the angles is 180, hence <FGH and <JKL are supplementary
Similarly;
Given
<AED = 45degrees
<BEC = 45degrees
Taking the sum
<AED + <BEC
= 45 + 45
=90degrees
Since the sum of complementary angles is 90degrees, hence <AED and <BEC are complementary

Answer:
Its D because the x axis can repeat itself
Step-by-step explanation:
A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.
Answer:
D, the last one
Step-by-step explanation:
A function, f(x), cannot have repeating x-values. Option D has the number 5 repeated twice, {1, 5, 5, 7}, in the x-column, therefore it cannot be a function of x.

An ironwoman race involves 3 swim legs and a beach run back to the start as shown in the figure.
What is the total distance covered in the race?
Answers
Answer:
593 m
Step-by-step explanation:
Total distance covered = perimeter of the trapezoid
= 100 + 75 + 250 + the length of the slant side (2nd swim)
Apply Pythagorean theorem to find the slant side (hypotenuse) since it forms a right triangle if we consider the distance between the parallel bases of the trapezoid.
Thus, let "x" represent the side length we are looking for.
Applying Pythagorean theorem, we have:
x² = 75² + (250 - 100)²
x² = 75² + 150²
x² = 28,125
x = √28,125
x = 167.705098 ≈ 168 m
✔️Total distance covered = 100 + 75 + 250 + 168 = 593 m
