mDE = 128 and mBC = 63. Find mZA. (The figure is not drawn to scale.)​

MDE = 128 And MBC = 63. Find MZA. (The Figure Is Not Drawn To Scale.)

Answers

Answer 1

Answer:

The angle formed by the intersection of 2 secants could be found out as: 1/2 (Arc DE - arc BC)

mDE = 128

mBC = 63

=> 1/2 (128 - 63)

=> 32.5 = mZA

Hope this helps!

The first row of a theater has 16 seats. There are 3 more seats in each row thereafter. How many seats are in the 25th row/

Answers

Answer: 88

Step-by-step explanation:

Given

The first row has 16 seats

then there are 3 more seats in each row

this follows an AP with the first term [tex]a=16[/tex] and common difference [tex]d=3[/tex]

So, no of seats in the 25 th row is

[tex]\Rightarrow a_{25}=a+24d\\\Rightarrow a_{25}=16+3\times 24\\\Rightarrow a_{25}=88[/tex]

Thus, there are 88 seats in the 25 th row

Please help What is the value of x. Look at picture.

Answers

Answer:

x = 50

Step-by-step explanation:

3x - 10 and 2(x + 10) are vertical angles and congruent , so

3x - 30 = 2(x + 10)

3x - 30 = 2x + 20 (  subtract 2x from both sides )

x - 30 = 20 ( add 30 to both sides )

x = 50

The lateral area of a cylinder is 100pi in^2. If its dimensions are reduced to one-fifth their original length, what would its new area be?

Answers

Answer:

4pi in^2

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

π = pi

r = radius

h = height

Let me illustrate with an example

A cylinder has the following dimensions

r = radius = 20  

h = height  = 10

lateral area = 2 x π x 20 x 10 = 400π

If dimensions are reduced to one-fifth their original length, new dimensions are

r = radius = 20  x 1/5 = 4

h = height  = 10 x 1/5 = 2

New lateral area = 2 x 4 x 2 x π = 16π

change in lateral area = 400π / 16π = 25

If dimensions are reduced by 1/5, lateral area would reduce by 25

100 pi / 25 = 4

Which of the following is not a Pythagorean triple?
O A. (5, 12, 13)
O B. (6, 8, 10)
O C. (9, 12, 15)
O D. (4,6,7)

Answers

Option D is correct, the  pair (4,6,7) is not a Pythagorean triple

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

A Pythagorean triple is a set of three positive integers a, b, and c that satisfy this theorem (a² + b² = c²).

Checking each of the given options, we have:

A. (5, 12, 13):

5² + 12² = 25 + 144 = 169 = 13². This is a Pythagorean triple.

B. (6, 8, 10):

6² + 8² = 36 + 64 = 100 = 10². This is also a Pythagorean triple.

C. (9, 12, 15):

9² + 12² = 81 + 144 = 225 = 15². This is a Pythagorean triple.

D. (4, 6, 7):

4² + 6² = 16 + 36 = 52 ≠ 7². This is not a Pythagorean triple.

a circle is drawn in a coordinate plane centered at (8,15) and a radius of 3 units.

Answers

Answer:

(x - 8)² + (y - 15)² = 9

Step-by-step explanation:

Assuming you want the equation.

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (8, 15 ) and r = 3 , then

(x - 8)² + (y - 15)² = 9
