Answer:
14.01m
Step-by-step explanation:
Perimeter of the rectangular wire = circumference of the circle
Perimeter of the rectangular wire = 2(L+W)
Perimeter if the rectangular wire = 2(12+10)
Perimeter if the rectangular wire = 2(22)
Perimeter if the rectangular wire = 44m²
Circumference of the circle = πd
44 = πd
d = 44/3.14
d = 14.01m
Hence the circumference of the circle is 14.01m
He starts at a speed of 4 fps.
He adds 2 fps of speed during each of 3 seconds, for a gain of 6 fps.
At the end of the 3 sec, his speed is (4 + 6) = 10 fps.
We know nothing about the direction in which he runs, so we're in no position to discuss velocity. The best we can do is to determine his final speed.
Answer:
Fruit smoothie: $3.4
Protein bar: $2.5
Step-by-step explanation:
Let x represent cost of fruit smoothie and y represent cost of protein bar.
We have been given that Jake buys a fruit smoothie and a protein bar for $5.90. We can represent this information in an equation as:
We are also told that Kobe buys 2 fruit smoothies and 4 protein bars. He pays $16.80. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, each protein bar costs $2.5.
Upon substituting 
in equation (1), we will get:
Therefore, each fruit smoothie costs $3.4.
