determine the length of a chord whose central angle is 75° in the circle with the radius of 12 inches.
Answers
Answer:
Step-by-step explanation:
other two sides joining center to the ends of chord=radius of circle=12 in
using cosine formula
[tex]cos A=\frac{b^2+c^2-a^2}{2bc} \\2bc cos~A=b^2+c^2-a^2\\\angle A=75^\circ\\b=c=r=12~in\\2*12*12~cos~75=12^2+12^2-a^2\\a^2=2*12^2-2*12^2 cos ~75\\a^2=2*12^2(1-cos 75)\\a=12\sqrt{2(1-cos~75)} \approx 14.6~inches[/tex]

You estimate that there are 32 candies in a bag.
and find there are actually 29 candies. Find the percent error. Round to the
nearest tenth of a percent if necessary.
a. 0.09%
C. 9.4%
b. 0.10%
d. 10.3%
Answers
Answer:
D. 10.3%
Step-by-step explanation:
Find the percent error using the formula:
percent error = | (observed - expected) / expected | x 100
32 is the observed value, and 29 is the expected value
Plug in these values to solve for the percent error:
percent error = | (observed - expected) / expected | x 100
percent error = | (32 - 29) / 29 | x 100
percent error = 10.3%
So, the correct answer is D. 10.3%

Answer:
B) -5, 5, -7, 7
Step-by-step explanation:
3x² - bx + 2
factor:
(3x - 2 )(x - 1) = 3x² - (5)x + 2 so 5 does work
(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work
(3x + 2 )(x + 1) = 3x² + 5x +2 = 3x² - (-5)x + 2 so -5 does work
(3x + 1 )(x + 2) = 3x² + 7x + 2 = 3x² - (-7)x + 2 so -7 does work

Tu bicicleta necesita ser reparada. Un mecánico cobra $ 22 por cada hora de trabajo y las piezas nuevas cuestan $ 23. El costo total para reparar la bicicleta es de $ 111. ¿Cuántas horas le tomó al mecánico arreglar la bicicleta?
Answers
Answer:
the number of hours that would be taken is 4
Step-by-step explanation:
The computation of the number of hours would be taken is shown below:
Let us assume the number of hours be x
Now according to the question
The equation is
$22x + $23 = $111
$22x = $111 - $23
x = 4 hours
Hence, the number of hours that would be taken is 4
What % of $30 is $21?
Answers
Answer:
70
Step-by-step explanation:
Answer:
x/100 x 30 = 21 (solve for x) x =70
I wish I could explain more but if your just lazy to do this i wont explain but if you honestly dont know I will explain, so solve for x you must multiply by a 100 on both sides and on the right side you multiply it to the fraction so x/100 x 100 = x (variable by itself means 1) then 21 x 100 = 21,000 therefore you are left with 30x since you are multiplying x and 30 together then you will divide by 30 on both sides to get x = 70

Identify the volume of the composite figure. Round to the nearest tenth.
Answers
Answer:
474.5 ft ³
Step-by-step explanation:
1) Find the volume of the cube
[tex]A=l^3[/tex] where l is the side length
Plug in 9 ft as l
[tex]A=9^3\\A=729[/tex]
Therefore, the volume of the cube is 729 ft³.
2) Find the volume of the cylinder
[tex]A=\pi r^2h[/tex] where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
[tex]A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5[/tex]
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
3) Subtract the volume of the cylinder from the volume of the cube
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.
