Dawson says that the expression (2 4/10+ 8 4/5)-3 1/5 is equal to a whole num do you agree explain hurry
If Dawson says that the expression [tex](2\frac{4}{10}+8\frac{4}{5})-3\frac{1}{5}[/tex] is equal to a whole number , then we can say that Dawson is correct .
The Mixed fraction expression is given as : [tex](2\frac{4}{10}+8\frac{4}{5})-3\frac{1}{5}[/tex] ;
first , we need to convert the mixed fraction in to simpler fractions ,
On converting ,
we get ;
the expression as : [tex](\frac{24}{10}+\frac{44}{5})-\frac{16}{5}[/tex] ;
taking the LCM of 10 and 5 as 50 ,
we get ;
⇒ [tex](\frac{24}{10}+\frac{88}{10})-\frac{16}{5}[/tex]
⇒ [tex](\frac{112}{10})-\frac{16}{5}[/tex]
Simplifying further ,
we have ;
⇒ [tex](\frac{112}{10})-\frac{32}{10}[/tex] ,
⇒ [tex]\frac{80}{10}[/tex]
= 8 , which is a whole number .
Therefore , we can agree with Dawson's statement that the expression [tex](2\frac{4}{10}+8\frac{4}{5})-3\frac{1}{5}[/tex] equals to a whole number "8" .
The given question is incomplete , the complete question is

Consider the line x+5y=6
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
[tex]x + 5y = 6[/tex] is perpendicular to [tex]y = 5x + \frac{6}{5}[/tex] and parallel to [tex]y = -\frac{1}{5}x + 2\\[/tex]
Step-by-step explanation:
First, convert the equation to standard form so that y is isolated.
x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) --> [tex]y = -\frac{1}{5}x + \frac{6}{5}[/tex]
A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).
[tex]-\frac{1}{5}[/tex] is perpendicular to [tex]-(\frac{-5}{1} )[/tex] which simplifies to 5.
A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.
[tex]y = -\frac{1}{5}x + \frac{6}{5}\\[/tex] is parallel to [tex]y = -\frac{1}{5}x + 2\\[/tex] just like [tex]y = -\frac{1}{5}x - \frac{100}{23}[/tex].

Step-by-step explanation:
First, we have to find out how much did she pay by taking
$5.00 - $1.40 = $3.60
So, she paid $3.60 in total. Then we find how many pounds of cheese she bought by taking
3.60 / 1.80 = 2 pounds of cheese
So, she bought 2 pounds of cheese.
Joe has 10 marbles . Ken has fewer marbles than joe witch inequality represent the number of marbles m that ken has
Answer:
k < 10
Step-by-step explanation:
An inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers.
Let k represent Ken. The closed side of < is the side the smaller number is going to be on. Ken has fewer marbles then Joe, therefore, k < 10 because Joe has 10 marbles.

A farm brings 15 tons of watermelon to market. Find a 90% confidence interval for the population mean cash value of this crop. What is the margin of error
The margin of error is $148.89. The upper limit is $2215 and lower limit is $1914.
What is a confidence interval with an example?In statistics, confidence is another word for probability. If you create a confidence interval, for instance, with a 95% level of confidence, you can be sure that 95 out of 100 times, the estimate will fall between the upper and lower values indicated by the confidence interval.
First we need to name some of the variables we are given:
n = 38 the sample size
x = 6.88 the sample mean
= 1.86 the population standard deviation
We need to find a 90% confidence interval for the mean price per 100 lbs of watermelon:
= 1-.90 = .10
/2 = .05
z(/2) = -1.64
-z(/2) = 1.64
This can give us a probability expression:
P(-1.645 < z < 1.645) = .90
The margin of error is calculated with the formula: E = z(/2)(/√n)
E = 1.645(1.86/√38) = $.4963(300) = $148.89
Then to calculate the upper and lower limit we add and subtract E from x:
lower limit = 6.88 - .4963 = $7.38(300) = $2214
upper limit = 6.88 + .4963 = $6.38(300) = $1914

A company is loading recliners and sofas onto a trailer that has a volume of about 3800 cubic feet. Each recliner takes up about 40 cubic feet and each sofa takes up about 80 cubic feet. The company wants the shipment to have at least 30 recliners and more than 25 sofas. Identify and interpret the ordered pair in the solution region.
The ordered pair that would be needed by the company for shipment can be loaded in the trailer as the pair will take only 3200ft³ of the volume of the trailer which is 3800 cubic feet.
How to calculate the ordered pair for shipment?The total volume of the trailer = 3800 cubic feet
The volume of each recliner = 40 cubic feet
The volume of each sofa = 80 cubic feet
The number of recliner needed = 30
The number of sofas needed = 25
The volume that the sofa will cover = 25 × 80 = 2000
The volume that the recliner will cover= 30 × 40 = 1200
Therefore the total volume both will take = 3200 cubic feet.

If the radius of a sphere is doubled, by how many times has its volume been increased
Answer:
8 times larger than the original
Step-by-step explanation:
In any three dimensional object, cube sphere, cone, etc., if all of its dimensions increase by a factor of x then its volume increases by a factor of x³
In this case the dimensions double, so the volume increases by a factor of 2³ = 8
Pat is making rectangular placemats each with area 1200cm2 she wants to braid trim around the edges how much trim does pat need for the placemat
Pat needs 16[tex]\sqrt{1200}[/tex]cm of trim for each placemat to braid trim around the edges.
To find out how much trim Pat needs for each placemat, we need to first find the perimeter of the rectangle.
The area of the rectangle is given as 1200 [tex]cm^2[/tex].
The perimeter of the rectangle is the sum of all four sides of the rectangle. If the length and breadth of the rectangle are L and B respectively, then the perimeter P can be calculated using the formula:
P = 2(L+B)
Now, let's find the length and breadth of the rectangle using the area formula,
Area = LB = 1200 [tex]cm^2[/tex]
so LB = 1200 [tex]cm^2[/tex]
Now we can substitute the value of L and B in the perimeter formula
P = 2(L+B) = 2(sqrt(1200)+sqrt(1200))
As the area of the rectangle is given as 1200[tex]cm^2[/tex] , the length and breadth can be calculated as [tex]\sqrt{1200}[/tex]cm.
So the perimeter of the rectangle is
P = 2*([tex]\sqrt{1200}[/tex] + [tex]\sqrt{1200}[/tex])
= 2*2[tex]\sqrt{1200}[/tex]
= 4[tex]\sqrt{1200}[/tex]cm
To find the total length of trim Pat needs for the placemat, we need to multiply the perimeter by the number of edges that need a trim. Since the edges are around the rectangular placemat, so it will be 4 edges.
So, the total length of trim Pat needs for the placemat is
P4 = 4[tex]\sqrt{1200}[/tex]*4 = 16[tex]\sqrt{1200}[/tex]cm
So Pat needs 16[tex]\sqrt{1200}[/tex]cm of trim for each placemat.

Answer: x = 60
Step-by-step explanation:
the equation is a^2 + b^2 = c^2.
If you draw out the problem, you plug in the information into the formula, so it would be...
x^2 + 80^2 = 100^2.
80^2 = 6,400 and 100^2 = 10,000.
x^2 + 6,400 = 10,000.
You subtract 6,400 from itself and 10,000 and then you get...
x^2 = 3,600.
You square both of those and your final answer will be x = 60.

Answer:
x = 62°
y = 118°
Step-by-step explanation:
Since the sum of interior angles of any quadrilateral is 360°, all of the interior angles in this image will add up to 360°.
Since the shape of the trapezoid is symmetrical, x is equivalent to 62°.
This means 62 + 62 + x + x = 360°
(360-(62+62))/2 = 118°
118 + 118 + 62 + 62 = 360°
x = 62°
y = 118°
