Answer:
Step-by-step explanation: 3²+12²=x² simplifies to 9+144=x² so 153=x² or x²=153.
Answer:B
Step-by-step explanation:
3.1x10^9 is putting 9 zero’s behind the 3.1
move the decimal point over 9 spaces which will leave you with 3,100,000,000
= 3.1 Billion
Let, the numbers = x,y
x/y = 3/5
total ratio units = 3+5 = 8
value of 1 unit = 135/8 = 16.875
So, numbers would be 3(16.875) & 5(16.875) = 50.625 & 84.375
so, your answer is 50.625 & 84.375
Direct Variation equation: y=kx, k=y/x
42/14=3
k=3
y=3x
y=3(90)
y=270
Answer:
101, 135, 131, 99, 138, 136, 140
