Answer:
a(n)= 120(1/2)^(n-1)
Step-by-step explanation:
60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2
a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)
Answer:120(1/2)^(n-1)
Step-by-step explanation:
60*x=120, x=60/120=1/2 so the sequence goes by a ratio of 1/2
a(n)=b(c)^n-1 and c=1/2. b= a(1)=120 so the formula is a(n)= 120(1/2)^(n-1)
A bouquet of flowers contains D daisies and T tulips and contains a total of F flowers. The number of daisies is two more than the number of tulips. Which equation matches this scenario?
A. D+2T=F
B. F−D+2=T
C. 2D+T=F
D. D+T+2=F
E. D+T=F+2
Answers
Answer: B (F-D+2=T)
Step-by-step explanation:
We know that daisies has 2 more than the tulips. (D+2 = T)
The answer is B
Flowers - Daises + 2 = T
Since daises has 2 more flowers than tulips, thats why theres a (+2)

-3n-4n-17=25
-15+7.5(2d-1)=7.5
Please show me how as well please :)
Answers
Answer:
-3n-4n = 25 + 17
-7n = 42
n= -6
the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.
-15 + 15d -7.5d =7.5
15d - 7.5d = 7.5 + 15
7.5d = 22.5
d = 3
for the part where theres 7.5(2d-1)
you multiply each number inside the bracket by 7.5, its called distributivity of multiplication
hope that answers your question
hope you understand what i wrote lol
good luck:)
Answer:
Question 1
Original Equation:
-3n-4n-17=25
Add 17 to both sides (cancels out the -17)
-3n-4n=42
Combine -3n and -4n.
-7n=42
Divide by -7
n = -6
Question 2
Original Equation:
-15+7.5(2d-1)=7.5
Distribute:
-15+15d-7.5=7.5
Add 7.5 to both sides:
-15+15d=15
Add 15 to both sides:
15d=30
Divide by 15:
d = 2

Write an equation to find the nth term. Then find ₐ₂₄

Answers
The equation to find the nth term is:
an = a+(n-1)d
Where a is the first term in the sequence, which is 1 and d is the difference, which in this sequence the next term is found by adding 2 to the previous term, so d = 2 and n is the term you want to find.
The equation is:
an = 1 + (n-1)2

It costs a baker 2x + 30 dollars to bake x muffins a day. Each muffin is sold for 5 dollars. How many muffins would the baker need to sell in a day in order to make enough revenue to cover the production cost?
WILL GIVE BRAINLIEST
Answers
Answer:
X = 10
Step-by-step explanation:
The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.
Then all you have to do is solve for the equation.
2x + 30 = 5x
Subtract 2x from each side
30 = 3x
Divide by 3
10 = x
The baker needs to sell 10 muffins in a day to make enough to cover the revenue.

In the second one, the parentheses are shifted. The shifting of parentheses indicates priority, and the associative property says in addition you can choose what you'd like to do first and it won't change the answer.

Answer:
A) 60 cents
B) 10 pounds of cabbage = 6 $
Step-by-step explanation:
The number of pounds of cabbage = (x)
The price = (y)
(x,y) = (5,3)
That means for 5 pounds of cabbage the price is 3 dollars.
A.
The price for 1 pound of cabbage can be found using this equation
5x = 3
x = 3/5 or 0.6
60 cents.
B.

Step-by-step explanation:
First we start off with the Pizza ($13)
Then we add our first 2 toppings to our pizza ($2 + $2 = $4)
And then we add our last 3 toppings to our pizza ($1 + $1 + $1 = $3)
Now we can add all of our costs up to get our answer
$13 + $4 + $3 = 20$

Answers
Answer:
Step-by-step explanation:
The natural numbers, whole numbers, and integers are all subsets of rational numbers. In other words, an irrational number is a number that can not be written as one integer over another.
Moderators i have not copied this ans
..? ⬇️
The natural (or counting) numbers are 1,2,3,4,5,
1
,
2
,
3
,
4
,
5
,
etc. There are infinitely many natural numbers. The set of natural numbers, {1,2,3,4,5,...}
{
1
,
2
,
3
,
4
,
5
,
...
}
, is sometimes written N
N
for short.
The whole numbers are the natural numbers together with 0
0
.
(Note: a few textbooks disagree and say the natural numbers include 0
0
.)
The sum of any two natural numbers is also a natural number (for example, 4+2000=2004
4
+
2000
=
2004
), and the product of any two natural numbers is a natural number (4×2000=8000
4
×
2000
=
8000
). This is not true for subtraction and division, though.
The rational numbers are those numbers which can be expressed as a ratio between two integers. For example, the fractions 13
1
3
and −11118
−
1111
8
are both rational numbers. All the integers are included in the rational numbers, since any integer z
z
can be written as the ratio z1
z
1
.
All decimals which terminate are rational numbers (since 8.27
8.27
can be written as 827100
827
100
.) Decimals which have a repeating pattern after some point are also rationals: for example,
0.0833333....=112
0.0833333....
=
1
12
.
The set of rational numbers is closed under all four basic operations, that is, given any two rational numbers, their sum, difference, product, and quotient is also a rational number (as long as we don't divide by 0
0
).
An irrational number is a number that cannot be written as a ratio (or fraction). In decimal form, it never ends or repeats. The ancient Greeks discovered that not all numbers are rational; there are equations that cannot be solved using ratios of integers.
The first such equation to be studied was 2=x2

, because 1.4142=1.999396
1.414
2
=
1.999396
, which is close to 2
2
. But you'll never hit exactly by squaring a fraction (or terminating decimal). The square root of 2
2
is an irrational number, meaning its decimal equivalent goes on forever, with no repeating pattern:
2‾√=1.41421356237309...

=
1.41421356237309...

and e

, the most important number in calculus:
e=2.71828182845904...
e

2
and the golden ratio), and transcendental numbers, which are not the solutions of any polynomial equation. π
π
and e

are both transcendental.
The real numbers is the set of numbers containing all of the rational numbers and all of the irrational numbers. The real numbers are “all the numbers” on the number line. There are infinitely many real numbers just as there are infinitely many numbers in each of the other sets of numbers. But, it can be proved that the infinity of the real numbers is a bigger infinity.
The "smaller", or countable infinity of the integers and rationals is sometimes called ℵ0
ℵ
0
(alef-naught), and the uncountable infinity of the reals is called ℵ1
ℵ
1
(alef-one).
There are even "bigger" infinities, but you should take a set theory class for that!

Not enough information is available to draw a conclusion.
Answers
Answer:
Science students
When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =

SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
