Answer:
the answer is 3/16.
Step-by-step explanation:
First, let's take a look at the expression itself.
We have to multiply 3/8 and 1/2, which gives us the expression of
3/8*1/2
then, we multiply the numerator by the numerator and get 3, then we multiply the denominator by the other denominator which gets us 16. We put the two parts together and get
3/16
which is not simplifiable. So 3/16 is the simplest answer we can get.
Use algebra for such problems
let, Angle COD = x
Angle KOD = y
Angle KPC = z
Given ,. x - y = 61° ( Equation 1 )
x - z = 53° ( Equation 2 )
Subtract 1st equation from 2nd and you'll get :
z - y = 8° ( Equation 3 )
Now since , x + y + z = 180° ( Equation 4 )
Add Equation 3 to Equation 4 and you'll get
x + 2z = 188° ( Equation 5)
From Equation 2 we know that , x -z = 53°
or, x = 53° + z ( Equation 6 )
Put this value of 'x' in Equation 5 and solve for z. you'll get :
(53° + z) + 2z = 188°
or
3z = 188 - 53 = 135°
solving for z we get
z = 45°
put this value of z in Equation 5
x + ( 2 x 45° ) = 188°
or
x = 188° - 90° = 98°
hence , Angle COD = 98°
Answer:
64
Step-by-step explanation:
Step 1: Define
9(a + 2b) + c
a = 3
b = 2
c = 1
Step 2: Substitute and Evaluate
9(3 + 2(2)) + 1
9(3 + 4) + 1
9(7) + 1
63 + 1
64
