Answer:
11π/4 (radians) or 495° (degrees)
Step-by-step explanation:
Convert 165° to radians:
165 * π/180 = 165π/180 = 11π/12
s = r/Ф
arc length = 3(11π/12) = 33π/12 = 11π/4
Convert back to degrees if asked to:
11π/4 * 180/π = 495° (Note that this is 165° * 3, see the pattern?)

How
Many small circles of radius 7cm
can be got from big
big circle of radius
35cm
Answer:
Let get x as a number of small circles.
Area of big circle = Area of all small circles
(Here . implies multiplication)
22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x
x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)
x = (35 . 35) /(7.7)
x = 25

Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.
What is the missing information in the paragraph proof?
Answer:
A. Inscribed Angle
Step-by-step explanation:
Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!
The missing information in the paragraph proof should be considered as the Inscribed Angle.
What is Inscribed Angle?In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral
Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.

3) [tex]x^{2}[/tex] + 4x - 21
Step-by-step explanation:
(x - 3)(x + 7)
Distribute:
x(x + 7)
-3(x + 7)
x(x) = [tex]x^{2}[/tex]
x(7) = 7x
-3(x) = -3x
-3(7) = -21
Combine like terms:
7x - 3x = 4x
Put it together:
[tex]x^{2}[/tex] + 4x - 21
Answer: x²+ 4x - 21
Let's do this step-by-step.
1. Apply the foil method. (formula: (a + b)(c + d) = ac + ad + bc + bd)
F - First
O - Outer
I - Inner
L - Last
= xx + x × 7 + (-3)x + (-3) × 7
2. Apply the minus and plus rules. + (-a) = -a
xx + 7x - 3x - 3 × 7
3. Simplify.
Convert xx into a exponent.xx ⇒ x²Subtract 7 by 3.7x - 3x = 4xMultiply 3 by 7.7 × 3 = 21Hence, the answer is x² + 4x - 21

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000
One Classroom has a volume of 564 cubic feet. Another classroom measure 17 feet tall , 8 feet long , and 5 feet wide. How much bigger is the volume of the second classroom compared to the first ?
Answer:
Step-by-step explanation:
Let d=difference. V=xyz
d=17(8)5-564
d=680-564
d=116 ft^3
So the second classroom is 116 cubic feet larger than the first.

Write an equation in slope-intercept form that represents the data.
Answer:
1) y = 5x + 100
2) y = -10x + 375
Step-by-step explanation:
The slope intercept form of an equation is expressed as y = mx+c
m is the slope
c is the intercept
1) Using the coordinate points (0,100) and (1, 105)
slope m = 105-100/1-0
m = 5/1
m = 5
Substitute m = 5 and (0,100) into the formula y = mx+c
100 = 5(0)+c
100 = 0 + c
c = 100
The required equation is y = 5x + 100
2) Using the coordinate points (0,375) and (5 325)
slope m = 325-375/5-0
m = -50/5
m = -10
Substitute m = -10 and (0,375) into the formula y = mx+c
375 = -10(0)+c
375 = 0 + c
c = 375
The required equation is y = -10x + 375
Write the fractions as a sum of unit fractions in two different ways
Answer:
Some unit fractions can be written as a sum of two different unit fractions in more than one way. Here are the ways to write 1 6: 1 6 = 1 7 + 1 42. 1 6 = 1 8 + 1 24. 1 6 = 1 9 + 1 18. 1 6 = 1 10 + 1 15. ( 1 6 = 1 12 + 1 12, but this has a repeat so it doesn't count.)

What is f(6)?
f(x) = 5x - 2
Answer:
f(6) = 28
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
FunctionsFunction NotationStep-by-step explanation:
Step 1: Define
f(x) = 5x - 2
f(6) is x = 6
Step 2: Evaluate
Substitute in x [Function]: f(6) = 5(6) - 2Multiplication: f(6) = 30 - 2Subtraction: f(6) = 28=========================================================
Explanation:
Everywhere you see an x, replace it with 6
f(x) = 5x - 2
f(6) = 5*6 - 2
f(6) = 30 - 2
f(6) = 28
Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Answer:
d) 28 in²
Step-by-step explanation:
A = bh
A = 7h
Find 'h' by using the Pythagorean Theorem:
3² + h² = 5²
9 + h² = 25
h² = 16
h = √16 = 4
A = 7×4 = 28
Answer:28
Step-by-step explanation:
Area of a parallelogram= bh
base-7
height- 4
using the Pythagorean theorem, [tex]5^{2}[/tex] - [tex]3^{2}[/tex]= [tex]\sqrt{16}[/tex] = 4
