Answer:
1,3,6,10,15,21,…..
These are all the sum of natural numbers upto the n
So, in this series
1st Term = 1
2nd Term = 1+2 = 3
3rd Term = 1+2+3 = 6
4th Term = 1+2+3+4 = 10
So,
Term - n = 1+2+3+….+n = n(n+1)/2
That’s your answer n(n+1)/2
Good Luck
Step-by-step explanation:
D=dimes
Q=quarters
D=32+Q
Q=?
D+Q=$11.6
D=(32*10)+Q=
$3.2+Q
$11.6-$3.2=$8.4
Each quarter must include 1 dime from now on because there’s 32 MORE dimes than quarters. $8.4/$0.35=24. (Divide 8.4 dollars by 1quarter+1dime, which is 35 cents.)
35 cents goes into $8.4 dollars 24 times. This means there’s 24 quarters and 24 more dimes. Returning to our original equations,
D=32+24
D=56
Q=24
This follows the rule of having 32 more dimes than quarters and the two add up to the correct amount, $11.60
There’s 56 dimes and 24 quarters
I need help with that too
1. Angle A is not 105degrees. As you can see on the horizontal line that it lies on, it's under 90degrees(acute). The angle aside from it is over 90degrees(obtuse).
2.Angle B is in fact not 75degrees.. By looking at the angle it's obtuse, over 90 degrees, so it can't be 75degrees.
Malpractice, Liability, Fire, and Homeowners' insurance are all different kinds of insurance besides Life and Automobile.
