1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.
2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800 /:100 divide both sides by 100
x=18 - its the answer
3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x
2400%=30x /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer
Answer:
Step-by-step explanation:
we know that
The rule to calculate the a_n term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
n is the number of terms
we have

Remember that In an Arithmetic Sequence the difference between one term and the next is a constant. and this constant is called the common difference
so


Find the 96th term of the arithmetic sequence
we have

substitute
I know I might be wrong on this but I think its28
Answer: 13 units
Step-by-step explanation:
d = sqrt[(-3-9)^2 + (-4 - - 9)^2]
= sqrt [(-12)^2 + (5)^2]
= sqrt (144 + 25)
= sqrt 169
= 13
