2.54 cm in 1 inch......how many inches in 51.78 cm...

51.78 / 2.54 = 20.4 inches <==

or this way...
2.54 / 1 = 51.78 / x....2.54 cm to 1 in = 51.78 cm to x inches
cross multiply
(2.54)(x) = 51.78)(1)
2.54x = 51.78
x = 51.78 / 2.54
x = 20.4 inches <==

A cube with sides numbered 1 to 6 is rolled 300 times. What is the best prediction for the number of times that a 1 or 2 would b
Leno4ka [110]
The answer is A.

Divide 300 by the number of faces of a cube.

Since there are 6 faces on a cube then we divide it.

300 ÷ 6 = 50.

So exactly 50 times.

Hope this helps :)

Q5 Q31.) Use the Pythagorean Theorem to find the length of the missing side of the right triangle. Then find the value of each o
Neporo4naja [7]

a^2 + b^2 = c^2

a = sqrt(c^2 - b^2) = sqrt (20^2 - 16^2)

= 12

sin\theta = a/c = 12/20

= 3/5

cos\theta = b/c = 16/20

= 4/5

tan\theta = a/b = 12/16

= 3/4

csc\pi = c/a = 20/12

= 5/3

= 1 2/3

sec\pi = c/b = 20/16

= 5/4

= 1 1/4
