Answer:
Step-by-step explanation:
=3+(18-6)+20÷4
=3+12+20÷4
=3+12+5
=20
use BODMAS rule (Bracket of Division, Multiplication, Addition, and Subtraction)
Its a because you will add 1.25 and 0.75 because it says each and of course 18 would be what it equals
Answer:
The answer is Perpendicular
The angles in an equilateral triangle are 60 degrees.
sin 60 = 9 / h where h is hypotenuse ( = side of the triangle)
h = 9 / sin 60 = 10.392
Perimeter = 3 * h = 31.18 to nearest hundredth
Answer:
3/2 or 1 + 1/2
i havent done fractions in a long time but this is what i got from memory
you turn the 2/3 into 4/6 so they can easily be added together to get 9/6 which can be simplified to 3/2 or in proper form 1 + 1/2
