Answer:
After 11 weeks, Darnell′s savings account will have a total of $8,360.
Step-by-step explanation:
The data provided is as follows:
n: 1 2 3 4
f (n): 260 360 460 560
Consider the data for f (n).
The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.
The nth term of an arithmetic sequence is:
[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]
Compute the value of f (11) as follows:
[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]
[tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]
Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

The perimeter of the triangle below is 4x + 3y. Find the measure
of the missing side.
Answer:
2x + 3y
Step-by-step explanation:
first you add the two known sides: (x-y)+(x+y) = 2x
Then you subtract the answer (2x) from the total perimiter (4x+3y) :
4x+3y-2x = (4x - 2x) + 3y = 2x + 3y
PLEASE HELP
Given 28-6x=2x-84 prove x=14.
Answer:
-56
Step-by-step explanation:
substitute x with 14 in the equation and both answers will be -56
28-6x = 2x -84
Add 6x to both sides:
28 = 8x -84
Add 84 to both sides
112 = 8x
Divide both sides by 8
X = 112/8
X = 14

A convenience store requires that Ayumi spend $4 or more if she wants to pay using a debit card. Donuts cost $0.80 each. A
bottle of orange Juice costs $1.20. Ayumi payed for 1 orange juice and d number of donuts. Write the equation that represent
the situation.
Answer
1.20+0.80d ≥ 4.00 is the equation. If you are trying to solve for the minimum of donuts she needs to buy so it is over $4.00, then it is 4
Step-by-step explanation:
So in the problem we know she already has bought one bottle of orange juice and needs to buy a certain amount of donuts but we know they are each 0.80 so that will become 0.80d. The 1.20 + 0.80d have to be greater than or equal to 4.00 so she can pay with the debit card and that is why we put the ≥ symbol.
Answer:
.80 × 4 =$3.20
orange juice is $1.20
d =.80×4 +1.20
d=$4.40

Find the LCM of x2 + x,x2-1,x2-x
Answer:
[tex]first \: \\ x {}^{2} + x \\ = x(x + 1) \\ \\ second \\ {x}^{2} - 1 \\ = (x) {}^{2} - (1) { }^{2} \\ = (x + 1)(x - 1) \\ \\ third \\ x {}^{2} - x \\ = x(x - 1) \\ \\ therefore \: \: lcm = x(x + 1)(x - 1)[/tex]
It helps you a lot ☺️Thank you ☺️☺️

Hi can somebody help me with this equation, please? 50=2(x+3)+10
Answer: x = 17
Step-by-step explanation:
1) Subtract 10 from both sides
40 = 2(x+3)
2) Divide both sides by 2.
20 = x + 3
3) Subtract 3 from both sides
17 = x
x = 17
Answer: x= 17
Step-by-step explanation:
17 plus 3= 20
then you multiply 20 times 2 (PEMDAS)
Then you get 40 and 40 + 10
equals 50
A local pizza shop has a membership program for frequent buyers. The membership costs $10 per month and members get a discounted price of $1.75 per slice of pizza. Autumn purchased a membership to this pizza shop.What would be the monthly cost for xx slices of pizza?
Answer:
Monthly cost = $10 + $1.75x
Step-by-step explanation:
Given the following :
Membership cost = $10 per month
Discounted price for members = $1.75 per slice of pizza
If Autum purchased the membership, the monthly cost for x slices of pizza
Monthly cost of x slices will be :
Membership cost + (discounted price * number of slices)
Monthly cost = $10 + ($1.75 * x)
Monthly cost = $10 + $1.75x

lin makes sparkling orange juice by mixing 3 liters of orange juice with 4 liters of soda water. Noah makes sparkling orange juice by mixing 4 liters of orange juice with 5 liters of soda water. How do the two mixtures compare in taste explain your reasoning
Answer:
Step-by-step explanation:
Lin makes sparkling OJ using the ratio
3:4. Meaning 3L orange juice for every 4L sparkling water.
Noah makes sparkling OJ using the ratio 4:5. Meaning 4L orange juice for 5L sparkling water.
If we said that they both used 12L of orange juice,
Lin would have to use 16L of sparkling water
Noah would have to use 15L of sparkling water
So for the same 12L of orange juice, Lin uses more sparkling water.
Therefore her sparkling OJ would be more diluted (less orange flavour since you added more water) and more bubbly than Noah's.

Tammy buys a 4-gigabyte memory card for her camera. Dijonea buys a memory card with twice as much storage as Tammy’s. One gigabyte is 1,024 megabytes. How many megabytes of storage does Dijonea have on her memory card?
Answer:
Dijonea have 8192 megabytes on her memory card
Step-by-step explanation:
Capacity of Tammy's memory card = 4-gigabyte
given that Dijonea buys a memory card with twice as much storage as Tammy’s
Thus,
Capacity of Dijonea's memory card = 2*Capacity of Tammy's memory card
Capacity of Dijonea's memory card = 2*4-gigabyte = 8-gigabyte
Given that
1 gigabyte = 1,024 megabytes
we have to find value of 8 gigabyte in terms of megabytes
for that we multiple both side in above equation by 8
1 *8 gigabyte = 1,024 *8 megabytes
8 gigabyte = 8192 megabytes
Thus, Dijonea have 8192 megabytes on her memory card
Jenny is making tie dyed shirts for her class with her school colors, blue and yellow she used a total of 8 ounces of fabric paint the amount of blue paint is 3 times the amount of yellow make a diagram to show the ratio of blue to yellow paint
Answer:
The ratio of blue paint to yellow paint is 3:1
Step-by-step explanation:
Let
x -----> the amount of blue paint in ounces
y ----> the amount of yellow paint in ounces
we know that
x+y=8 -----> equation A
x=3y -----> equation B
Solve the system by substitution
Substitute equation B in equation A
3y + y = 8
4y = 8
y = 2
Find the value of x
x = 3(2) = 6
therefore
The amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces
Find the ratio
To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint
x/y = 6/2 = 3/1
That means -----> Of every 4 parts of paint, three parts are blue and one part is yellow.
