Answer: 60

Step-by-step explanation:

If the entire blue length is 100 and one of the parts of that is 64, the other part is 36.

So by the geometric mean theorem, letting the length of the dotted altitude be y,

$\frac{64}{y}=\frac{y}{36}\\y^{2}=64 * 36 =2304\\y=48$

So if y=48, by the Pythagorean $x=\sqrt{48^2 + 36^2}=60$ theorem,

All of the given questions(#65 to #70) are AP(s).

Formula to be used: a(n) = a(1) + (n - 1)d

Pronounced as:

nth term = 1st term + (n - 1)d, where d is the common difference.

*d = difference of any two consecutive terms.

65):

1st term = 2, d = 6 - 2 = 4

Therefore,

11th term = 2 + (11 - 1)4 = 42

66):

1st term = 5, d = 15 - 5 = 10

Therefore,

16th term = 5 + (16 - 1)10 = 155

67):

1st term = 19, d = 39 - 19 = 20

Therefore,

21st term = 19 + (21 - 1)20 = 419

68):

1st term = 8, d = 38 - 8 = 30

Therefore,

36th term = 8 + (36 - 1)30 = 1058

69):

1st term = 1/2, d = 1 - 1/2 = 1/2

Therefore,

101st term = 1/2 + (101 - 1)1/2 = 101/2

70):

1st term = 0.75, d = 1.50 - 0.75 = 0.75

Therefore,

151st term = 0.75 + (151 - 1)(0.75) = 113.25

Lily went shopping with alan. lily spent $11.20 for 3.60 kg flour and 1 kg sugar. alan spent $20 for 5 kg flour and 2.50 kg suga

Anna007 [38]

Or 1 kilogram = 2 pounds 3 ounces. To change from KILOGRAMS TO POUNDS we can multiply by 2.2. So is we have a 2kg bag of flour and we want to know what this is in pounds we can work it out like this: 2kg = 2 x 2.2lbs = 4.4lbs. A. Try these. 1) 3kg = lbs. 2) 6kg = lbs. 3) 7kg = lbs. 4) 12kg = lbs. 5) 14kg = lbs. 6(

Answer:

okay so you would make a line straight across the middle of the spherical shape. The line that goes all the way across is the diameter. If you were to cut that line in half that would be the radius.

Step-by-step explanation:

The first circle shown in the picture provided would be an example of diameter, and the second circle would be an example of the radius. You could just make up a value, for example say the diameter is 10, the radius would be 5.
