The 3rd term of an arithmetic sequence is -1 and the 7th term is -13. find the explicit formula for this sequence. What is a22?
Answers
Answer: Hopefully the math terms won't confuse anyone.
So in the series, a_3 = -1 and a_7 = -13. Since it's an arithmetic sequence, all the terms in the series can be represented as:
a_n = a_0 + n * k
where n is the nth number. K is a constant you add to reach the next term, and a_0 is the starting constant.
a_7 = a_0 + 7 * k
a_3 = a_0 + 3 * k
solving this system gives you that
k = - 3 and a_0 = 8
Hence:
a_22 = 8 + 22 * -3 = -58

There are 15 students in a class. 9 of them play basketball, and 11 of them play soccer. How many students in the class play both soccer and basketball
Answers
We will see that the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
How to find the number of students that play both sports?
We do know that in the class, there are 15 students.
Such that:
9 of them play basketball.11 of them play soccer.If you add these numbers, you get:
9 + 11 = 20
This gives more than the number of students that we have, to get the minimum number of students that play both sports we subtract the number of students:
20 - 15 = 5
5 students play both sports, but this is the minimum number.
There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.
So the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9

Answers
Answer:
k=10
do long or synthetic division. the quotient = 3x + 22 with remainder 81
with long division first divide x into 3x^2 to get 3x. Then
3x times (x-4) = 3x^2-12x
subtract that from 3x^2+kx to get (k-12)x bring down the -7 to get
(k-12)x -7
you want a remainder of 81, so you want -4 times a constant to = -88 (-7-(-88)=81
4 x 22 =88. 22 is the constant
22=12+k

Practice using the work formula. A bathtub that holds 42 gallons of water is filling at a rate of 4 gallons per minute. How long will it take to fill the tub? Enter your answers into the boxes. Enter the time t as a decimal. W = rt =
gal = gal/min. t ga • gal/min = t min = 1
Answers
Answer: The percentage of the tub after 6 minutes is 30 %
Step-by-step explanation: The calculation can be done as follows
1 minutes= 4 gallons
6 minutes= 4×6
= 24 minutes
If the bathtub can hold 80 gallons of water then the percentage of the tub after 6 minutes can be calculated as follows
= 24/80
= 0.3 × 100
= 30 %
Hence the percentage of the tub will be filled after 6 minutes is 30 %

Mark says he has 4/10 of a dollar. Matt says he has 40/100 of a dollar. Matt says he has more money than Mark. Is he correct? Why?
Group of answer choices
A.Matt is not correct because they have the same amount of money.
B.Matt is not correct because Mark has more money.
C.Matt is correct because 40 is greater than 4.
D.Mark is correct because 100 is greater than 10.
Answers
Answer:
A
Step-by-step explanation:
If you simplify 40/100, you should get 4/10, which is still the same amount that Mark has.
You simplify by finding the greatest common factor between 40 and 100. In this case, it is 10. So you divide 40 by 10 and 100 by 10 to simplify.

Berts store has more. Hope this helps :)
Birt's store has a greater ratio of books to games in comparison to Gloria's store.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given the table:
Bert’s store
Books: 4,8,12,16,20.
Game: 6,12,18,24,30
Gloria’s store
Books: 5,10,15,20,25.
Games: 8, 16, 24, 32,40,
Since the fourth data of the birt store has an equal base to the third data of Gloria's store.
Thus, we can compare the data from the upper tables
So, 16 > 15
thus,
we can say that Bert's store has a greater ratio.
