Jasper's parents keep a chart on the wall where they mark how much Jasper grows each year. When Jasper was 15, he grew 1/10 of an inch and when he was 16, he grew 3/10 of an inch. In total, how much did Jasper grow in during those two years?
Write your answer as a fraction or as a whole or mixed number.
Answers
Answer:
In order to find the total inches Jasper grew during the two years, we have to add up the total inches he grew when he was 15 and the total inches he grew when he was 16. Therefore, we have to add 1/10 and 3/10 together.
1/10 + 3/10 = 4/10, or 2/5.
Therefore, Jasper grew a total of 2/5 inches in those two years.

How many shirts did the company buy if their total cost is $110? Write your answer as a number only.
0 points
Answers
Answer:
Cost of shirt
c = $5.50x
$115.5
20 t - shirts
Step-by-step explanation:
The dependent variable here is Cost of shirt
T - shirt cost , c equation of any number of customers :
The cost per shirt = $5.50
Let the number of shirts purchased = x
Hence,
c = $5.50x
The cost 21 shirts
x = 21
c = $5.50 * 21 = $115. 5
With c = $110
number of shirts, n equals
110 = 5.50x
110/ 5.5 = x
20
= 20 at shirts

Grandma decides to pay for her new granddaughter's education. She gives
her one penny on her first birthday, and doubles the gift every year. Round
to the nearest hundredth. Do not use a dollar sign, numerical values only.
What will be the total of all the gifts on the girl's 18th birthday?
Answers
Answer:
Around 0.40
Step-by-step explanation
If she doubles the gift every year, do 18x2=36, 36 rounds to 40 or 0.40.
The total of all the gifts on the girl's 18th birthday given from her grandma for this considered case is evaluated as 2621.43 dollars
What is the sum of the terms of a geometric series till nth term?Lets suppose the geometric sequence has its initial term is [tex]a[/tex], multiplication factor is r, then, its sum is given as:
[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]
(sum till nth term)
The sequence would look like [tex]a, ar, \cdots, ar^{n-1},\cdots[/tex]
For this case, we are specified that:
Grandma gives 1 penny on first birthday of her granddaughterGrandma increases the gift by doubling the previous birthday gift.That shows that the gift amounts each year will form a geometric sequence where a = 1, and r = 2 (as amounts are doubled).
The gift amounts would look like:
[tex]\\1, 2, 4, \cdots\\or\\1, 2\times 1, 2^2 \times 1, \cdots[/tex]
We have to find these terms' sum till 18th term(18th term is the gift of her 18th birthday).
Thus, we have: n = 18, a = 1, and r = 2.
The sum will be:
[tex]S_n = \dfrac{a(r^n-1)}{r-1} = \dfrac{1(2^{18}-1)}{2-1} = 2^{18} - 1 = 262143 \: \rm cents[/tex]
There are 100 cents in 1 dollars,
Thus, 1 cent = 0.01 dollars,
and thus, 262143 cents form 2621.43 dollars.
Thus, the total of all the gifts on the girl's 18th birthday given from her grandma for this considered case is evaluated as 2621.43 dollars

1. There are ____ terms.
2. The sign of each term in the series ___.
3. What is the last term in this series?
Answers
Answer:
Use the attachment below.
Step-by-step explanation:
There will be 5 terms, there will be an alternative sign of the series and their last term will be 1/16.
What is a series?A sequence's series is the total number of terms in the sequence.
A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Given that the series
∑(-1/2)^K and this summation goes from k =0 to k = 4
Now the question is asking how many terms are in there, the sign of each term in the series, and the last term in this series.
Now if you take k =0 and find the first term then it will be
(-1/2)⁰ = 1 so the first term will be 1.
Similarly, you can put k =1,2,3,4 so there will be a total of 5 terms.
The sign of each term will be alternative since because of negative somethings power will be positive if power is odd and negative if power is even.
In the last term put k = 4, and you will get (-1/2)⁴ = 1/16.
