Answer:
a₁₅ = 86x - 68
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2x + 2
d = a₂ - a₁ = 8x - 3 - 2x - 2 = 6x - 5 , then
a₁₅ = 2x + 2 + 14(6x - 5)
= 2x + 2 + 84x - 70
= 86x - 68

The China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. If the list price is $58.75, what is the trade discount? What is the net price?
Answer: See explanation
Step-by-step explanation:
Since the complement is the difference between 100% and discount rate. Since the China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. Therefore, the discount rate will be 80% and the complement 20%.
Therefore, the trade discount will be:
= List price × Trade discount rate
= $58.75 × 80%
= $58.75 × 0.8
= $47
Net price = List price - Trade discount
= $58.75 - $47
= $11.75

The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
Answer:
12566.4 mm²
Step-by-step explanation:
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
TSA = Total Surface Area
CSA = Curved Surface Area
TSA of open cylinder = CSA of cylinder + area of base or top
= 2πrh + πr²
= πr(2h + r)
From the above question:
r = 50mm
h = 15mm
Hence,
= π × 50 (2 × 15 + 50)
= π × 50 (30 + 50)
= π × 50(80)
= π × 4000
= 12566.370614mm²
Approximately = 12566.4 mm²
The Surface Area of the petri dish with no lid = 12566.4 mm²
Factor 48-8x to identify the equivalent expressions
Choose two answers.
Answer:
8(6 - x)
Step-by-step explanation:
I'm not exactly sure why the question asks for two answers.
We need to find the highest common factor that goes into both 48 and -8x.
That common factor is 8.
48 / 8 = 6
-8x / 8 = -x
Now, we factorise.
8(6 - x)

I have the answer I just have this one question. Will all the paint fit into the bucket?
There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow?
Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.
Answer:
brandon
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of pints of yellow color become pint, in which the ampunt of yellow color is pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so
So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.

0
Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24
The missing angle is 24 degrees

Answer:
16.
solution:
perimeter = 64
4l = 64
l= 64/4
l=16
Answer:
Step-by-step explanation:
since it's a square we know the 4 sides are the same length.
64 / 4 = 16
so each side is 16.... now use pythagoras to solve for GE since we know the two legs of the triangle .. both 16
16^2 + 16^2 = GE^2
512 = GE^2
[tex]\sqrt{512}[/tex] = GE
22.627417 = GE
GE = 22.6 ( rounded to nearest 10th )

At the craft store, Janice bought a bag of green and yellow marbles. She received 14 green marbles and 11 yellow marbles. What percentage of the marbles were green?
Answer: 56%
Step-by-step explanation:
Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:
= 14 + 11 = 25 marbles
Number of Yellow marbles = 11
Number of Green marbles = 14
Total number of marbles = 25
The percentage of the marbles that were green will be:
= Number of Green marbles / Total marbles × 100
= 14/25 × 100
= 14 × 4
= 56%

Answer:
.........................
Step-by-step explanation:
.................................................
Answer:
99.7% of customers have to wait between 8 minutes to 30 minutes for their food.
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 18 minutes
Standard Deviation, σ = 3 minutes
We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.
Empirical Formula:
Almost all the data lies within three standard deviation from the mean for a normally distributed data.
About 68% of data lies within one standard deviation from the mean.
About 95% of data lies within two standard deviations of the mean.
About 99.7% of data lies within three standard deviation of the mean.
Thus, 99.7% of the customers have to wait:
`
Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.

What is the gradient of the line that passes through the points (0,0) and (3,3)?
Answer:
1
Step-by-step explanation:
the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as
rise/run
or
change in y value/change in x value
or
(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).
We have two coordinates (0,0) and (3,3)
Therefore,
x1 = 0, y1 = 0
x2 = 3, y2 = 3
If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]
