A)<span>calculate the cost of one T-shirt
</span>
So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height
subisute
base=4(5)
base=20
height=5
Answer:
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
Step-by-step explanation:
The formula for simple interest is I = PRT ÷ 100
Casandra's equation = I= 500(0.025)(3)=$37.50
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
Answer:
This can be done in a total of 10 ways
Step-by-step explanation:
This is a selection problem.
What we are trying to do is to properly select 3 week long camps from the total 5. we are looking for the number of ways in which we can do this.
Now, since this is a selection problem, the proper mathematical term and approach to use is the COMBINATION
Mathematically, having r items to pick from a total n, the number of ways to do this is nCr ways
which is mathematically equivalent to;
n!/(n-r)!r!
now applying this to the problem at hand, what we have is 5C3
= 5!/(5-3)!3! = 5!/2!3! = (5 *4)/2 = 20/2 = 10 ways
Answer:
17.51
Step-by-step explanation:
Notes: Circumference= 2 times pi times r
Diameter is double the radius (2r)
How to solve: You just need to divide 55 feet by pi
2(pi)(r)/( pi) = 55/(pi)
2r = 17.51
diameter = 17.51
