find the area of the shaded sector of the circle
Answers
Answer:
(175/9)π m²
Step-by-step explanation:
Area of the shaded sector = θ/360 × πr²
Where,
θ = 180° - 110° = 70°
r = ½(20) = 10 m
Substitute
Area = 70/360 × π × 10²
Area = 7/36 × π × 100
Area = (7×100)/36π
Area = (700/36)π = (350/18)π = (175/9)π m²
Each week Lucy makes ten dollars in allowance. Write an integer to represent the amount of money she makes.
Answers
Answer:
Just multiply the number of weeks by 10
Step-by-step explanation
The current integer is 10/1 for 10 dollars made every 1 week.
So, if two weeks pass by, the integer will be 20/2 for 20 dollars made every
week.
If you continue this process by multiplying by 10, you'll get your chart.

What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
In arithmetic, sequence d represents the common difference.
The sequence is given in the question, as follows:
1,2,3,4,…
We have to determine the next number in the sequence using inductive reasoning
The pattern in the given sequence is that each number is one greater than the previous number.
Using inductive reasoning, we can conclude that the next number in the sequence would be 5.

Answer:
77/85
Step-by-step explanation:
Given:
cos(A) = 4/5
sin(B) = 15/17
Find:
cos(A-B)
Solution:
From your knowledge of Pythagorean triples, you know that one of them is (3, 4, 5) and another is (8, 15, 17). Using your imagination, or by drawing the triangles, you can determine the needed trig functions to be ...
sin(A) = 3/5
cos(B) = 8/17
__
Alternatively, you can use the Pythagorean identity to find ...
sin(A) = √(1 -cos²(A)) = √(1 -(4/5)²) = √(9/25) = 3/5
cos(B) = √(1 -sin²(B)) = √(1 -(15/17)²) = √(64/289) = 8/17
__
Then application of the angle difference formula is straightforward.
cos(A -B) = cos(A)cos(B) +sin(A)sin(B)
cos(A -B) = (4/5)(8/17) +(3/5)(15/17) = (32 +45)/85
cos(A -B) = 77/85
_____
Some graphing calculators can express the result ...
cos(arccos(4/5) -arcsin(15/17)) ≈ 0.90588235294
... as the fraction 77/85

A rectangular auditorium seats 2142 people. The number of seats in each row exceeds the number of rows by 9. Find the number of seats in each row.
Answers
9514 1404 393
Answer:
51
Step-by-step explanation:
Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...
s(s-9) = 2142
s² -9s +4.5² = 2142 +4.5² . . . . . complete the square
(s -4.5) = √2162.25 . . . . . . . . take the positive square root
s = 4.5 +46.5 = 51 . . . . . . . add 4.5
The number of seats in each row is 51.

can someone help me do 1/3 divided by 4 please?
Answers
The answer is
1/12
Explanation:
In order to divide
1/3 by 4
1st: you must find the reciprocal of the
denominator, which is
1/4
2nd: Then you multiply
1/3
by the reciprocal
So
1/3 divided by 4
will now be
1/3 x 1/4= 1/12
First you have to find the reciprocal of the denominator which is 1/4 then you multiply 1/3 by the reciprocal
So instead of it being
1/3
—-
4
It is 1/3 x 1/4=1/12

Answer:
Arc DE = 70°
Arc RST = 206°
Step-by-step explanation:
arc DE + arc DC = 180° because EC is a diameter
7x + 7 + 11x + 11 = 180°
combine like terms:
18x + 18 = 180°
subtract 18 from both sides of the equation:
18x = 162°
divide both sides by 18:
x = 9
Arc DE = 7(9) + 7 = 70°
arc RST = 2(x + 103) = 2x + 206
arc RFT = 2(x + 77) = 2x + 154
arc RST + arc RFT = 360°
so:
2x + 206 + 2x + 154 = 360°
combine like terms:
4x + 360 = 360
4x = 0
x = 0
arc RST = 2x + 206 = 206°

Answers
Answer:
(a) and (b) are not equivalent
(c) is equivalent
Step-by-step explanation:
Given
[tex]\frac{25^m}{5}[/tex]
Required
Determine an equivalent or nonequivalent expression
[tex](a)\ 25^{m-1[/tex]
We have:
[tex]25^{m-1[/tex]
Apply law of indices
[tex]25^{m-1} = \frac{25^m}{25}[/tex]
This is not equivalent to [tex]\frac{25^m}{5}[/tex]
[tex](b)\ 25^{2m - 1}[/tex]
We have:
[tex]25^{2m - 1}[/tex]
Apply law of indices
[tex]25^{2m - 1} = \frac{25^{2m}}{25}[/tex]
This is not equivalent to [tex]\frac{25^m}{5}[/tex]
[tex](c)\ 5^{2m-1}[/tex]
We have:
[tex]5^{2m-1}[/tex]
Apply law of indices
[tex]5^{2m-1} = \frac{5^{2m}}{5^1}[/tex]
[tex]5^{2m-1} = \frac{5^{2m}}{5}[/tex]
Evaluate the numerator
[tex]5^{2m-1} = \frac{25m}{5}[/tex]
This is an equivalent expression
