Answer:
2 years
Step-by-step explanation:
Let B = age on Ben
and age of Izzy =I
B =4I
B = 6+I
Gives 6+I = 4I
6 = 3I
I =2 years and B = 4x2 = 8years
Age of Izzy = 2 years
Similarity ratio is a ratio of two figures having the same side.
Ratio can be rate but rate can never be ratio. In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.<span>

Answer:
78.54
Step-by-step explanation:
Area of a circle = pi time radius power of 2
A = pi*r^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.54
First take the exponent and 'kill' the 2, by - it from the 3, which gives you just 2x1 (Sorry can't make the one an exponent on this.). Then you take the 2x and times it by itself, so that you end up with 4x. Now you add the 4x and the 5x, to give you 9x. Then -5x from the 9x. to give us 4x again. Now you minus the 2. so that we have 4x-16 dived by x=? from there you dived 4x by 1x to give you 4x. Then you add the -16 over. so that you have 4x=16, then just dived 16 by 4. In the end x=4.
