P=2(W + L)
p= 2W + 2L
98=2W + 2(6W)
98=2W + 12W
98=W
98/14=14W/14
W=7
L= 6W
L = 6(7)
L= 42
CHECK
p=2(7 +42)
p=2(49)
p= 98
Area of a rectangle = W X L
Area of a rectangle = 7 X 42
Area of a rectangle = 294
Answer:
Trevon is 28 years old
Step-by-step explanation:
Riggs =x
Trevon =7+x
7+x+x=49
7+2x=49
2x=49-7
2x=42
x=21
Trevon is 21+7= 28 years old
Answer: 7 pm
Step-by-step explanation: Rotating the hour hand 90 degrees will be 3 hours. So 4 plus 3 = 7
blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
