Answer(1):
Given that h(y)=2y-7.
h(8) means plug y=8 into h(y)=2y-7.
h(8)=2*8-7=16-7=9
Hence C) 9 is the final answer.
Answer 2:
(7/8) = (m/32)
to solve for m, we begin by cross multiply
8m=7*32
8m=224
m=28
Hence choice C) 28 is final answer.
Reflection symmetry occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other.
Rotational symmetry is to check if the given picture is symmetric after some rotation.
Answer 3:
Letter "E" will have
B) the letter has reflection symmetry only
So B) is correct.
Answer 4:
Which statement is true?
Letter "Z" will have
B) the letter has rotation symmetry only
Hence B) is correct.
Answer 5:
Letter "X" will have
A) the letter has both reflection and rotation symmetry
Hence A) is correct.
I think this is more of an opinion question. What someone could solve mentally may not be the same as someone else's.If it were my worksheet, I'd circle all of them but it may be different for you.
At your level, I'd probably circle:
54 - 10
93 - 20
and 39 - 2
Answer:
interest rate is 38.68 %
Step-by-step explanation:
Given data
installment = $60
time = 36 months = 36/12 = 3 years
principal = $1000
to find out
interest rate
Solution
we know student pay $60 for 36 months
so he pay total = 60 × 36 = 2160
total amount pay by student = $ 2160
so we can find interest rate by given formula
rate = (1/time)(amount/Principal - 1)
put the value time amount and principal here
rate = (1/3)(2160/1000 - 1)
rate = 0.386667
interest rate is 38.68 %
Answer:
72 is the least common multiple
