You lose an online auction for an autograph. Your losing bid of $28 is 40% of the winning bid. How much less was your bid than the winning bid?
Answer:
My bid was $42 less than the winning bid.
Step-by-step explanation:
The winning bid is x.
$28 is 40% of x
0.4x = 28
x = 28/0.4
x = 70
The winning bid was $70.
$70 - $28 = $42
Answer: My bid was $42 less than the winning bid.

32,8,83,88,58,58,66,11,34,23 calculate the range
Answer:
80
Step-by-step explanation:
After spending some time arranging the numbers in order, we get the sequential order as 8, 11, 23, 32, 34, 58, 58, 66, 83, 88.
Next, we need to find the range. The Range of a data set is the difference between the largest and smallest number.
Thus, 88 - 8 = 80 as the range.Find the height of a rectangle if the base is 24 in and the perimeter is 102 in.

Solving using systems of equations
Answer: There are no possible solutions because
If you were to plot these two equations on the graph you would notice they are parallel because both have the same slope (3x) but still have different intercepts. This means there are no possible solutions as in order to have a solution for x and y they need to intercept and the point of interception is the solution for x and y but that cannot happen in a system of equations that result in parallel lines ( they’ll never intercept)
Answer:
Ø
Step-by-step explanation:
These equations are parallel, meaning they have SIMILAR rate of changes [slopes]. To prove it, convert the second equation from Standard Form to Slope-Intercept Form:
[tex]\displaystyle y - 3x = -13 \hookrightarrow y = 3x - 13 \\ \\ \left \{ {{y = 3x - 13} \atop {y = 3x - 11}} \right.[/tex]
As you can see, both equations have a rate of change of 3, meaning we CANNOT obtain a solution here, therefore we have no solution.

NO LINKS!! A blimp, suspended in the air of 500 feet, lies directly over a line from Soldier Field to the Adler Planetarium on Lake Michigan (see the figure). If the angle of depression from the blimp to the stadium is 32° and from the blimp to the Planetarium is 23°, find the distance between Soldier Field and the Adler Planetarium.
Answer:
1978 ft (nearest foot)
Step-by-step explanation:
Using the Alternate Interior Angles theorem, we can deduce that the left base angle of the triangle is 32° and the right base angle of the triangle is 23°.
The triangle can be divided into 2 right triangles, both with height of 500ft (see attached diagram).
Using the tan trig ratio, we can calculate the base of each triangle.
[tex]\mathsf{\tan(\theta)=\dfrac{O}{A}}[/tex]
where:
[tex]\theta[/tex] = angleO = side opposite the angleA = side adjacent the angleLeft triangle
let [tex]x[/tex] = the base length
[tex]\implies \tan(32)=\dfrac{500}{x}[/tex]
[tex]\implies x=\dfrac{500}{\tan(32)}[/tex]
Right triangle
let [tex]y[/tex] = the base length
[tex]\implies \tan(23)=\dfrac{500}{y}[/tex]
[tex]\implies y=\dfrac{500}{\tan(23)}[/tex]
To find the distance between the Soldier Field and Adler Planetarium, simply sum [tex]x[/tex] and [tex]y[/tex]:
[tex]\implies \dfrac{500}{\tan(32)}+\dfrac{500}{\tan(23)}=1978.093447...[/tex]
Therefore, the distance is 1978 ft (nearest foot)

A study found that 9% of dog owners brush the dogs teeth. Of 578 dog owners, about how many would be expected to brush their dog’s teeth? explain.
Answer:
52
Step-by-step explanation:
Step 1: Our output value is 578.
Step 2: We represent the unknown value with [tex]x[/tex].
Step 3: From step 1 above, [tex]578=100%[/tex]%
Step 4: Similarly, x=9%
Step 5: This results in a pair of simple equations:
578 = 100% (1)
x = 9% (2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
578/x = 100% /9%
Step 7: Again, the reciprocal of both sides gives
x/578 = 9 /100
⇒ x = 52.02
Therefore, 9% 578 is 52.02
Round:
Answer: About 52 dog owners are expected to brush their dogs teeth.

Kellie wants to cover part of the lawn with pavers to make a nice place to put a table and some chairs. This space will be a rectangle with an area of 108 square feet, and the rectangle will be 3 feet longer than wide. What will the dimensions of this rectangle be? In other words, what will the length and width be?
For the record, the formula for the area of a rectangle is A = LW.
8a) Clearly write out the equation you would use to answer the question.
8b) Answer the question. What will the dimensions be? Please write your answer as a complete sentence with appropriate units.
8a)
x = width
x+3 = length, since its 3 ft longer than the width
A = length*width
A = LW
A = (x+3)*x
A = x^2+3x
Set this equal to 108 since this is the area of the rectangle.
Answer: x^2 + 3x = 108=========================================================
8b)
x^2+3x = 108
x^2+3x-108 = 0
Use the quadratic formula with a = 1, b = 3, c = -108
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(3)\pm\sqrt{(3)^2-4(1)(-108)}}{2(1)}\\\\x = \frac{-3\pm\sqrt{441}}{2}\\\\x = \frac{-3\pm21}{2}\\\\x = \frac{-3+21}{2} \ \text{ or } \ x = \frac{-3-21}{2}\\\\x = \frac{18}{2} \ \text{ or } \ x = \frac{-24}{2}\\\\x = 9 \ \text{ or } \ x = -12\\\\[/tex]
Ignore the negative solution because we cannot have a negative width.
x = 9 is the width
x+3 = 9+3 = 12 is the length being 3 longer.
The rectangle is 12 ft by 9 ft to get an area of 12*9 = 108 sq ft, which confirms the answer.
Answer: 12 feet by 9 feetThe expression 3b +2.2 is equal to for b = 1.8.

Chase is constructing equilateral triangle EFG inscribed in a circle.
He begins by using a compass to draw circle X. He then uses a straightedge to draw a diameter of the circle and labels the endpoints D and E.
How can Chase find points F and G?
A.
Points F and G are endpoints of a chord that is perpendicular to and bisects DE.
B.
Points F and G are the points where circle X intersects a congruent circle centered at D.
C.
Points F and G are the points where circle X intersects a congruent circle centered at E.
D.
Points F and G are points of intersection of two congruent circles centered at D and E
Answer: A
Step-by-step explanation:
To construct equilateral triangle in a circle F and G as D. Points F and G are points of intersection of two congruent circles centered at D and E. The correct answer is option A.
What is a circumscribed circle?The circumscribed circle or circumcircle of a polygon in geometry is a circle that passes through each of the polygon's vertices. This circle's circumcenter and circumradius are its center and radius, respectively.
It should be noted that an equilateral triangle simply means a triangle that has all the sides and angles to be equal.
After drawing the diameter of the circle through the center, it's important to open the compass to a width that's equivalent to the radius of the circle.
In this case, it can be deduced that Points F and G are points of intersection of two congruent circles centered at D and E.
