Step-by-step explanation:
this sequence has 8 terms and the common ratio or multiplication factor is -1/2.
we could add these 8 numbers manually or use the formula :
Sn = a1(1 - r^n)/(1 - n)
when r < 1 (like in our case -1/2).
S8 = 128(1 - (-1/2)⁸)/(1 - -1/2) =
= 128(1 - 1/256)/(3/2) = (128×255/256)/(3/2) =
= (255/2)/(3/2) = 255/2 × 2/3 = 255/3 = 85

A movie theater sells popcorn in a reusable bucket for $3.50. They offer refills for $1.00 each.
Write an equation in slope-intercept form to model the cost in dollars, y, for x refills.
Answers
Answer:
3.50= 1x + i dont know B
Step-by-step explanation:
the equation is y=mx + b
The equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50= 1x + b.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given that movie theater sells popcorn in a reusable bucket for $3.50. They offer refills for $1.00 each.
The value of y is popcorn cost = $3.50
The slope will be $1.00
Therefore, the equation is y=mx + b
Plug the values;
3.50= 1x + b
Hence, the equation in slope-intercept form to model the cost in dollars, y, for x refills is 3.50= 1x + b.

What is an equation of the line that passes through the points (5,2) and (-5,-6) PLEASE ANSWER
Answers
Answer:
y = 4/5 x - 2
Step-by-step explanation:
Find for slope first:
m = (y2 - y1) / (x2 - x1)
= [(-6) - 2] / [(-5) - 2]
= -8/-10
= 4/5
Solve for b. Use (5, 2)
y = mx + b
2 = 4/5 (5) + b
2 = 20/5 + b
2 = 4 + b
2 - 4 = b
-2 = b
Substitute the value of m and b.
y = mx + b
y = 4/5 x + (-2)
y = 4/5 x - 2

Alexandra has a stand in the marketplace where she sells ground cumin. She has a fixed amount of weekly expenses, and she sells her cumin for \$7.20$7.20dollar sign, 7, point, 20 per kilogram. If she sells 909090 kilograms of cumin, her weekly net profit is \$414$414dollar sign, 414.
Answers
Answer:
Alexandra's weekly expenses is $234
Step-by-step explanation:
Selling price of 1 kg cumin = $7.20
She sells amount of cumin = 20 kg
Selling price of 90 kg cumin = 90 \times 7.20
Selling price of 90 kg cumin =648
We are given that his weekly profit is $414
We are supposed to find his weekly expense
So, Expense = SP - Profit
Expense = 648-414
Expense=$234
Hence Alexandra's weekly expenses is $234

Mrs. Gildner took a survey of the 30 students in her math class. Of the 30 students surveyed, 18 of them said that chocolate is their favorite ice cream flavor. 4 students listed vanilla as their favorite flavor. The remaining students indicated that strawberry is their favorite kind of ice cream.
What is the ratio of chocolate to strawberry? SIMPLIFY if possible!

Answer: 9:4
Step-by-step explanation: Total is 30. Add 18 and 4 to see how many students were already surveyed, (22) and then subtract that from 30. Then you get 8, so the ratio is 18:8. Then simplify by dividing both numbers by 2, so you get 9:4. Hope that helps :)
Identify the value of y.
9y+6 = 3y+3+7+26
Answers
Answer:
y=5
Step-by-step explanation:
9y+6 = 3y+3+7+26
arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.
9y - 3y = 3 + 7 + 26 -6
6y / 6 = 30 / 6
Now divide both sides by 6 in order for y to be alone.
y = 5

A person can pay $7 for a membership to the science museum and then go to the museum for
just $1 per visit. What is the maximum number of visits a member of the science museum can
make for a total cost of $46? Write an equation and solve. Show all work!
Answers
Answer:
39 visits.
Step-by-step explanation:
In order to solve, we must add the cost of the membership and the cost of the visits to get the sum of 46.
$7 is the cost of the membership, so thats going to be the first number we add. If you revist the museum, you will need to pay $1. Now to save time and space, I will not continusely write $1 until we get to 46, but instead, subtract 46 from 7. The difference we get will be the number of visits. I will be using the variable v to represent the difference/maximim number of visits a member of the science museum can make for a total cost of $46.
Current Equation: 7+1v = $46.
46 - 7 = 39.
7+1(39) = 46
I agree with the previous answer. It indeed is 39.
46-7=39 (7 - price of the membership)
39/1=39 (1 - price of the tickets)
