Put 22.5% in a equivalent fraction 225/1000 reduce to 9/40
Answer:
5 + 32 = answer
Step-by-step explanation:
PEMDAS
parentheses
exponents
multiplication
division
addition
subtraction
the parts that are in "part" are what i solved in that step and what is in 'a number' is the answer to that step
"(2 + 3)" + 4 (to the power of 2) times "(5 - 3)"
'5' + "4 (to the power of 2)" times '2'
5 + '16' times 2
5 + "16 times 2"
5 + '32'
the answer is 5 + 32. I believe you can solve the last part so technically you solved the problem and I just helped a little. :D
Complement of an alngle means what you need to add to it to make 90 degrees
comlement of angle x is y such that x+y=90
so if complement of angle x is 25, that means the angle x is found by
x+25=90
minus 25 both sides
x=65 degrees
the angle measures 65 degree
Answer:
a) N = 240 ways
b) N = 303,600 ways
c) N = 10 ways
Step-by-step explanation:
a) Given
General course consist of one course from each of 4 groups.
Social Science = 5 options
Humanities = 4 options
Natural sciences = 4 options
Foreign language = 3 options.
Therefore the total number of possible ways of selecting one each from each of the 4 groups is:
N = 5×4×4×3 = 240 ways
b) if four people are chosen from 25 member for four different positions, that makes it a permutation problem because order of selection is important.
N = nPr = n!/(n-r)!
n = 25 and r = 4
N = 25P4 = 25!/(25-4)! = 25!/21!
N = 303,600 ways
c) The number of ways by which 5 tosses of coin can yield 2 heads and 3 tails.
N = 5!/(5-5)!(2!)(3!)
N = 5×4/2
N = 10 ways
Answer: Many utility companies promote energy conservation by offering discount rates to ... who keep their energy usage below certain established subsidy standards. A recent EPA report notes that 70% of the island residents of Puerto Rico have reduced their electricity usage sufficiently to qualify for discounted rates.
