Hyp^2 = a^2 + b^2
sqrt (hyp) = 2
hyp = 4
hyp^2 = 16 then from above a^2 + b^2 = 16

Step-by-step explanation:
5z+15=65
5(10)+15=65
Answer: B has greater spread than A.
Step-by-step explanation:
Since we have given that
Set A: {38, 12, 23, 48, 55, 16, 18}
Range of A = Highest - Lowest
Range of A = 55 - 12
Range of A = 43
Set B:{44, 13, 24, 12, 56}
Range of B = Highest - Lowest
Range of B = 56 - 12
Range of B = 44
Since Range of B is more than range of A.
Hence, B has greater spread than A.
Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
Let's call Maria 'M' and Sal 'S'
Maria is 12 1/2 years older than Sal.
S + 12 1/2 = M
The sum of their ages is 28 1/2
S + M = 28 1/2
Solve for M in the second equation:
28 1/2 - S = M
The first equation is:
<span>S + 12 1/2 = M
</span>
Set them equal to each other since they both are equal to M.
28 1/2 - S = <span>S + 12 1/2
</span>
Basicaly, n = S, so your correct answer is B. 28 1/2 - n = n + 12 1/2
