Is Tangent To Circle A. Determine The Length Of 2.Question 4 Options:1) 52) 83) 134) 12

Answers

Answer 1

Answer:

Not sure about the question but I believe you are looking for the length of AC.

Then the answer is choice 3) 13

Step-by-step explanation:

AC² = 5² + 12² = 25 + 144 = 169

AC =√169 = 13

Answer 2

The required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.

What is a circle?

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on coordinate plane and r is the radius of the circle.

Here,
C is the point outside the circle and tangent drawn to the circle from C to B of length 12, the radius of the circle is 5. Since the radius is always perpendicular to the circle's tangent,
So
ABC is right angle triangle
AB = 5 ; BC = 12
Now applying the Pythagorean theorem
AC² = AB² + BC²
AC  = √(5² + 12²)
Ac = √(25+144)
AC = √169
AC = 13

Now,
AC = AE + EC
(AE = AB)
AC = AB + EC
13 = 5 + EC
EC = 8


Thus, the required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.

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.

Answer:

Step-by-step explanation:

x/y equals to 6/3. Simplify it- 6(numerator) can go into 3(denominator) twice, so therefore it is 2.

Or you can divided 6(numerator) by 3(denominator), and get 2.

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

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%
