  A.  72

  B.  7

  C.  35+63 = 7(5+9)

Step-by-step explanation:

A. The two numbers differ by 1, so can have no common factors. Their LCM is their product:

  LCM(8, 9) = 8·9 = 72

__

B. It helps to know your times tables.

  35 = 5·7

  63 = 7·9

The GCF of these numbers is their only common (prime) factor: 7.

  GCF(35, 63) = 7

__

C. Using the distributive property:

  35 +63 = 7·5 +7·9

  35 +63 = 7(5 +9)

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
