Step-by-step explanation:
24/8=3
3x5=15
the perimeter is 18.7 units
Answer: Angle 2: 45°
Step-by-step explanation:
All triangles add up to 180, so all you would so is take both of those angles and subtract them from 180, so basically 180 - 135
Answer:
17/72
Step-by-step explanation:
Let's make this equation easier to read.
.5/36 + 16(1/72)
Start by remembering PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
This is the order in which you will solve the problem. So multiplication first, then division, and finally addition.
Multiply 16 and 1/72
16/1 x 1/72 multiply across to get 16/72 which can be reduced to 2/9.
Divide .5 (or 1/2) by 36. To do this, multiply by the reciprocal of 36
1/2 x 1/36 = 1/72
Your equation is now
2/9 + 1/72
Your common denominator is 72, so multiply top and bottom of 2/9 by 8.
16/72 + 1/72 = 17/72
