Answers
Answer:
1 and 4
Step-by-step explanation:
ANSWER
first is the geometric series
EXPLANATION
a geometric series is a sequence of numbers whose first term is non zero and each of the succeeding terms is equal to the Prcedding term multiply by a constant number.
if a = first term
and constant number = d
then
GP is given by
a,a r , a r^2 ,a r^3 .............and so on
in first
a = 1/2
and d = 1/2
and hence it is an GP

The ratio of basketball card to football cards is 2 : 3.
What is the ratio?
A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now it is given that,
Number of football cards = 42
Number of basketball cards = 28
Hence,
Ratio of basketball cards to football cards = Number of basketball cards/Number of football cards
⇒Ratio of basketball cards to football cards = 28/42
⇒Ratio of basketball cards to football cards = 2/3
⇒Ratio of basketball cards to football cards = 2:3
Therefore,The ratio of basketball card to football cards is 2 : 3.
To learn more about ratio :
#SPJ2
28 : 42
7 into 28 is 4 and 7 into 42 is 6
28 : 42 = 4 : 6
2 into 4 is 2 and 2 into 6 is 3
28 : 42 = 4 : 6 = 2 : 3
So the simplified ratio of baseball cards to football cards is 2 : 3.

Now we use the cosine theorem to get third side
B) $780
C) $928
D) $2,412.80
Answers
Answer:
The correct answer is D. $2412.8
Step-by-step explanation:
Sum of all liabilities Barry bought = 100 + 300 + 50 = $450
But $500 is deductible so there will be no charge on the liabilities.
Now, Sum of base premiums = 450 + 245 + 148 + 85 = $928
Also, the rating factor = 2.60
∴ Total base premium = (Sum of base premium) × Rating factor
= 928 × 2.60 = $2412.8
Therefore, the correct answer is D. $2412.8
=928
928×2.60
=2,412.8

25(3n+3)+10(n+1)+5n=265.
Thus:
90n+85=265
Subtracting 85, we have:
90n=180
Therefore, n=2. As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
9 quarters 3 dimes 2 nickels
9*.25+2.25
3*.10=.30
2*.5=10
2.25+.30+.10=2.65
