Answer: 19 + (-27)
Step-by-step explanation:
Go to where 30 degrees is on the unit circle and find the y-coordinate. That is sin30.
Answer:
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
you simplify
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
Step-by-step explanation:
Using PEMDAS,
27-10=17
17*4=68
64/68=0.94 (rounded to the nearest hundredth)
Answer: y= 2
Step by step: Multiply 2 and 1 to get 2
