The record ski jump for women is 110 meters. What is this length in feet?
Answer:
The record ski jump for women is 360.89 feet.
Step-by-step explanation:
The record ski jump for women is 110 meters.
Record ski jump = 110 m
We need to find what is this length in feet.
We have the conversion 1 m = 3.28084 ft
Using the above conversion
We will get
1 m = 3.28084 ft
110 m = 110 x 3.28084 = 360.89 ft
The record ski jump for women is 360.89 feet.

Larry's dining room table measures five feet in diameter. what scale diameter will he use if the scale he is using is 1 inch = 2 feet?
Answer: 2.5 inches.
Step-by-step explanation:
The given statement : Larry's dining room table measures five feet in diameter.
i.e. We are given that the diameter of Larry's dining room table = 5 feet
The scale used by him 1 inch =2 feet
i.e. [tex]\text{1 feet =}\dfrac{1}{2}\text{ inch}[/tex]
Now, [tex]\text{5 feet =}5\times\dfrac{1}{2}\text{ inches}=2.5\text{ inches}[/tex]
Therefore, the scale diameter he will use = 2.5 inches.
The excel function ________ would be used to find the lowest score on a series of student test scores. min median sum dmin
The Excel function you should use to find the lowest score in a series of test scores is the MIN function. It determines the smallest number in a set of values.
Explanation:The Excel function that should be used to find the lowest score on a series of student test scores is the MIN function. This function allows you to determine the smallest number in a set of values. For instance, if you have the scores in cells A1 to A10, you would write the formula as =MIN(A1:A10).
It's important to note that the other options provided, such as median, sum, and dmin, would not accurately find the lowest score. The median would find the middle score, sum would add all the scores together, and dmin is a database function that extracts the smallest number from a selected database column based on the specified conditions.

As a salesperson at Scrapbooks and Treasures, Alysse receives a monthly base pay plus commision on all that she sells. If she sells $400 worth of merchandise in one month, she is paid $388. If she sells $1,000, she is paid $520. Find Alysse's salary when she sells $3,300 worth of merchandise.
Answer:
Step-by-step explanation:
In order to solve this we just have to create a system of equations, because we have to unknown values, for the base salary we are going to use X and for the comission we will use Y, now we know that when she sold $400 in merchandise she earned $388 and and when she sold $100 se got paid $520 both equations would look like this:
[tex]x+400y=388\\x+1000y=520][/tex]
Now we can solve them by elimination, multiplying one function by -1.
[tex](-1)(x+400y=388)= -x-400y=-388\\x+1000y=388\\1000y-400y=132\\600y=388\\y=\frac{132}{600} \\y=0.22=22%[/tex]
Now we know that the percentage that she earns is 22% of the merchandise she sells.
Now to know how much does she makes on her base pay we just put the value into one of the functions:
[tex]x+1000y=520\\x+1000(.22)=520\\x+220=520\\x=300[/tex]
So her base pay is $300.
To calculate how much she will earn when she sells $3,300 in merchandise we just put that value into the formula:
[tex]x+3300y=\\300+3300(.22)\\300+726=1026[/tex]
So when she sells 3300 she will make 1026 total.

A. The hexagon is circumscribed about the circle.
B. Each vertex of the hexagon lies inside the circle.
C. The circle is congruent to the hexagon.
D. Each vertex of the hexagon lies outside the circle.
E. The circle is tangent to each side of the hexagon.
Answer: A. The hexagon is circumscribed about the circle.
D. Each vertex of the hexagon lies outside the circle.
E. The circle is tangent to each side of the hexagon.
Step-by-step explanation:
Given: A circle is inscribed in a hexagon.
Then the hexagon is circumscribed about the circle.
Each vertex of hexagon lies outside the circle.
As each side of hexagon is just attached to the circle not passing through the circle, thus the circle is tangent to each side of the hexagon.
Since circle is a closed curve and hexagon is regular polygon with 6 sides, they cannot be congruent because they have different shapes.
The area of a rectangle is 28 ft2 , and the length of the rectangle is 1 ft more than twice the width. find the dimensions of the rectangle.
The length is 8feet and the width of the rectangle is 3.5feet
Let the width of the rectangle be represented by w
Let the length of the rectangle be represented by = 2w + 1
Therefore, based on the information given, the equation to solve the question will be:
w(2w + 1) = 28
2w² + w = 28
2w² + w - 28 = 0
2w² + 8w - 7w - 28 = 0
2w(w + 4) - 7(w + 4) = 0
2w - 7 = 0
2w = 0 + 7
2w = 7
w = 7/2
w = 3.5
The width is 3.5 feet
The length will be:
= 2w + 1
= 2(3.5) + 1
= 7 + 1
= 8
The length is 8feet and the width is 3.5feet

find the center of the circle that can be circumscribed about triangle EFG, E(6,4) F(6,2) and G(10,2)
Final answer:
The center of the circumscribed circle about triangle EFG with given vertices is found by calculating the perpendicular bisectors of the triangle's sides and locating their intersection point, which is the center (8,3).
Explanation:
To find the center of the circumscribed circle about triangle EFG with vertices E(6,4), F(6,2), and G(10,2), we need to determine the perpendicular bisectors of at least two sides of the triangle and then find their intersection point, which will be the center of the circumscribed circle.
First, find the midpoint of side EF, which has the same x-coordinate (since E and F have the same x-coordinate), so the midpoint is (6,3).Next, we need the equation of the perpendicular bisector of EF. Since EF is vertical, its perpendicular bisector is a horizontal line that passes through the midpoint, hence the equation is y = 3.Then, find the midpoint of side FG. As the endpoints have the same y-coordinate, the midpoint will have that y-coordinate (2) and the x-coordinate will be the average of the x-coordinates of F and G, which is (6+10)/2 = 8. So, the midpoint of FG is (8,2).The slope of side FG is 0 (since it's horizontal), so the slope of its perpendicular bisector is undefined, meaning it's a vertical line. Consequently, the equation of this perpendicular bisector is x = 8.Last, by solving the system of equations formed by the two perpendicular bisectors x = 8 and y = 3, we find the intersection point, which is the center of the circumscribed circle: (8,3).What is the slope of a line that is perpendicular to the line v= 3/4x-6?
A. 3/4
B. -4/3
C. -3/4
D. 1/6
The slope of line which is given to be perpendicular to the line represented by equation "v = (3/4)x - 6" is : (b) -4/3.
To determine the slope of a line that is perpendicular to the given line v = (3/4)x - 6, we use the property that perpendicular lines have slopes that are "negative-reciprocals" of each other.
The slope of the given line is 3/4. To find the slope of the perpendicular line, we take the negative reciprocal of 3/4.
The negative reciprocal of 3/4 is -4/3. So, the slope of the line that is perpendicular to the given-line v = (3/4)x - 6 is -4/3.
Therefore, the correct answer is (b) -4/3.

Help please. Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
A.5√2 /2
B.5√3
C.5√2
D.5√3 /2
Answer: The value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]
Step-by-step explanation: We are given to find the value of the variable 'x' in the figure.
We can see that the figure is a right-angled triangle with the length of the hypotenuse as follows:
h = 5 units.
Now, with respect to the angle of measure 45°, the length of the perpendicular is x units.
That is, p = x units.
From relations between trigonometric ratios, we have
[tex]\sin 45^\circ=\dfrac{\textup{perpendicular}}{\textup{hypotenuse}}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{p}{h}\\\\\\\Rightarrow \dfrac{1}{\sqrt2}=\dfrac{x}{5}\\\\\\\Rightarrow x=\dfrac{5}{\sqrt2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{(\sqrt2)^2}\\\\\\\Rightarrow x=\dfrac{5\sqrt2}{2}.[/tex]
Thus, the value of the variable is [tex]x=\dfrac{5\sqrt2}{2}.[/tex]

the bottom of the pool is 15 x 30 = 450 sq feet.
you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet
then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet
for a total of 450 +300 +150 = 900 square feet
1 can covers 250 sq ft
so 900/250 = 3.6
