Step-by-step explanation:
Five friends ate lunch together. They each paid the same amount the total cost of all five meals was $51.94 which included a 6% sales tax, what was the cost of one meal before tax was added?
Given:
Total number of friends = 5
Total cost of all five meals = $51.94
Sales tax = 6%
To find:
The cost of one meal before tax was added.
Solution:
Let x be the cost of all five meals before tax.
Then, Amount of tax = 6% of x
According to he question,
[tex]x+\dfrac{6}{100}x=51.94[/tex]
[tex]x+0.06x=51.94[/tex]
[tex]1.06x=51.94[/tex]
Divide both sides by 51.94.
[tex]x=\dfrac{51.94}{1.06}[/tex]
[tex]x=49[/tex]
So, the cost of all five meals before tax is $49.
Divide this cost by 5 to get the cost of one meal before tax was added.
[tex]\dfrac{49}{5}=9.8[/tex]
Therefore, the cost of one meal before tax was added, is $9.8.
In which figure is point G a centroid?

Answer:
Step-by-step explanation:
You didn't provide us with correct choice
The centroid of a triangle is the point of intersection of its medians.
The lines that pass through the centroid of a triangle divides the side lengths of the triangle into equal halves.
The figure whose centroid is point G is triangle LMN.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, From the attached image, we have the following highlights
There is no evidence that the lines that pass through point G divides the three sides of triangle ABC into equal halves
The lines that pass through point G divides the three sides of triangle LMN into equal halves
The above highlights mean that:
Point G is the centroid of triangle LMN.
Hence, the figure whose centroid is point G is triangle LMN.

Thomas has a bag with 6 purple and 5 blue marbles. If his friend Nick pulls 2 marbles from the bag, what is the probability of him getting 2 purple marbles. 30/121 30/121 21/22 21/22 3/11 3/11 11/21
Answer: 3/11
Step-by-step explanation:
Number of purple marbles = 6
Number of blue marbles = 5
Total number of marbles = 6 + 5 = 11
The probability of picking the dust purple marble will be 6/11. After a purple marvel has been picked, there'll be 5 purple marbles left and the total number of marbles will be 10, therefore the probability of picking the second purple marble will be 5/10.
Therefore we then multiply the probability of picking the first purple marble by the probability of picking the second purple marble. This will be:
= 6/11 × 5/10
= 6/11 × 1/2
= 3/11

You have 50 apples at the start and every hour you get 200 more apples, sweet!
Now let's look at the chart.
The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.
Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.

3 +5.2.c = 1 - 2.87
Answer:
-0.0936538462
Step-by-step explanation:
Start by solving the right side of the equation
1 - 2.87 = -1.87
now we have:
3 + 5.2c = -1.87
subtract 3 from both sides to get:
5.2c = -4.87
divide both sides by 5.2 to get:
-0.0936538462

Rachelhasalreadywritten10pages,andsheexpectstowrite1pageforeveryadditionalhourspentwriting.HowmanyhourswillRachelhavetospendwritingthisweekinordertohavewrittenatotalof27pages?
Answer:
17 hours
Step-by-step explanation:
Rachel has already written 10pages, and she expects to write 1page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27pages?
The illustration can be modelled using the equation
y = 10 + 1(x)
y = 10 + x
Where,
y = total number of pages
x = number of hours
10 = pages already written
If y = 27 pages, find x
y = 10 + x
27 = 10 + x
27 - 10 = x
17 = x
x = 17 hours
Rachel have to spend 17 hours writing this week in order to have written a total of 27pages

Answer:
The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].
The slope of the line graphed below would be 2.
Using the formula Rise/Run, you can solve the slope using the graph. The Rise would be equal to 2 units, with the Run being one. This means that for every 1 unit on the x-axis, there are 2 units displaced on the y-axis. Therefore, the slope would be 2/1.

The mean of 4 numbers is 40 what is the sum of the 4 numbers
Answer:44.445
Step-by-step explanation:
Let the 5 numbers are a,b,c,d, and e
so (a+b+c+d+e)/5=40
So a+b+c+d+e=5*40=200
Now let the next 4 no are p,q,r,s then
(p+q+r+s)/4=50
p+q+r+s=200
Thus sum of all 9 numbers
=(a+b+c+d+e) +(p+q+r+s)
=200+200=400
thus average of these 9 numbers
If the mean of 4 numbers is 40. Then the sum of the numbers will be 160.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.
The mean of 4 numbers is 40.
Mean = (Sum of the number) / (Number of the observation)
Mean = 40
Number of the observation = 4
Then the sum of the numbers will be
40 = (Sum of the number) / 4
Sum of the numbers = 160

On a conveyor belt, there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds. Let x and y represent the weights of the two boxes on the conveyer belt.
a. Write an inequality that describes the weight limitation in terms of x and y.
b. Two boxes are to be placed on the conveyor below. The first box weighs 175 pounds. What is the maximum weight of the second box?
Answer:
The maximum weight of the second box is 125 pounds. (The box can weight less than 125 pounds, but no more than 125 pounds since the total weight of the boxes cannot be more than 300 pounds.)
Step-by-step explanation:
x+y ≤ 300
175+y ≤ 300
Substract 175 on both sides:
y ≤ 125
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300 and the maximum weight of second box can be 125 pounds.
We have a conveyor belt such that there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds.
It is given in the question to assume let x and y represent the weights of the two boxes on the conveyer belt.
We have to find -
a) - inequality that describes the weight limitation in terms of x and y.
b) - If two boxes are to be placed on the conveyor belt and first box weighs 175 pounds then what is the maximum weight of the second box?
What is inequality?Inequality in mathematics is a relation that is used to compare two or more algebraic expressions.
According to the part 'a' of the question -
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300
According to part 'b' of the question -
x = 175 pounds
The maximum weight of second box can be found out by substituting the value of 'x' in inequality in part a.
175 + y ≤ 300
y ≤ 125
Hence, the maximum weight of second box can be 125 pounds.
