Answer:
0.00736 Sq. Yard size of decagon is used
Step-by-step explanation:
Given
Each side of Decagon [tex]= 8[/tex] centimeter
Area of Decagon
[tex]A = \frac{5}{2} a \sqrt{5+2\sqrt{5} }[/tex]
Here a is the side of decagon
Substituting the given values, we get -
[tex]A = 2.5 * 8 * 3.077\\A = 61.54[/tex]Square centimeter
1 square centimeter = 0.000119599 square yard
Area in yard = 0.00736 Sq. Yard
slope intercept equation from graph
Answer:
y = 2x+4
Step-by-step explanation:
Hi there,
In this linear graph, we notice that the slope is 2 since the [tex]\frac{rise}{run}[/tex] is [tex]\frac{2}{1}[/tex]. We also notice that this line crosses the y-axis at x = 0. Based on the information we found, we can put it in the linear equation y = mx+b.
Here is what the m and b means for reference:
m = slope
b = y-intercept
The final answer will be y = 2x + 4.
Hope this answer helps clarify this concept. Feel free to ask me questions. Cheers.
On a particular flight, the airline's income was $95,280 for a jumbo jet carrying 290 passengers. If a first-class ticket costs $680 and a coach ticket costs $288, how many of each ticket were sold for the flight?
Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:
[tex]f+c=290[/tex]
The total income was $95,280. Therefore:
[tex]680f+288c=95280[/tex]
We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:
[tex]85f+36c=11910[/tex]
From the first equation, we can subtract f from both sides:
[tex]c=290-f[/tex]
Substitute:
[tex]85f+36(290-f)=11910[/tex]
Distribute:
[tex]85f+10440-36f=11910[/tex]
Simplify:
[tex]49f=1470[/tex]
So:
[tex]f=30[/tex]
From the previous equation:
[tex]c=290-f[/tex]
Substitute:
[tex]c=290-30=260[/tex]
30 first-class tickets were sold and 260 coach tickets were sold.

Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000. Which inequality can be used to determine the amount of money the family still needs to save? 2764 + x > 5000 2764 + x Greater-than-or-equal-to 5000 2764 + x Less-than-or-equal-to 5000 5000 + x > 2764
Answer:
B. 2764 + x Greater-than-or-equal-to 5000
Step-by-step explanation:
A. 2764 + x > 5000
B. 2764 + x Greater-than-or-equal-to 5000
C. 2764 + x Less-than-or-equal-to 5000
D. 5000 + x > 2764
Current balance of their account = $2,764
They need a balance of at least $5,000
At least in inequality means greater than or equal to
Let x = remaining balance to make at least $5,000
The inequality is
2764 + x greater than or equal to 5,000
The answer is B. 2764 + x Greater-than-or-equal-to 5000
The inequality that can be used to determine the amount of money she still needs to save is x ≥ $5000 - $2,764.
What inequality can be used to represent the amount that still needs to be save?The following are inequality signs and what they mean:
> means greater than< means less than≥ means greater than or equal to ≤ less than or equal toThe inequality sign to be used is ≥.
The amount that still needs to be saved: x ≥ $5000 - $2764

the width of a rectangle is 2 in less than its length the area is 24 square inches find the dimensions of the rectangle
Answer:
6,4
Step-by-step explanation:
Create a system of equations
l-2=w
w*l=24
Substitute
l-2*1=24
l=6
6-2=4
w=4
Dimensions of the rectangle are 6inch and 4 inch.
What is rectangle?
"Rectangle is a quadrilateral whose all angles are right angle and opposite sides are parallel and equal in measurement."
What is dimensions?" Dimension is measurement of any object such as length, width and height of any object."
What is area?"Area is a space occupied by an object."
Let 'l' be the length of the rectangle.
According to the question,
Width = l - 2
Area= 24 square inches
Formula used
Area of a rectangle = length x width
[tex]24 = l[/tex] × [tex](l-2)[/tex]
⇒[tex]24[/tex] = [tex]l^{2} -2l[/tex]
⇒ [tex]l^{2} -2l -24=0[/tex]
⇒[tex]l^{2} -6l+4l -24 =0[/tex]
⇒[tex]l(l-6) +4(l-6) =0[/tex]
⇒[tex](l-6)(l+4) =0[/tex]
⇒[tex]l=6[/tex] or [tex]l= -4[/tex]
length cannot be negative.
Therefore, [tex]l=6[/tex]inch
⇒width = [tex]6-2[/tex]
⇒ width = 4 inch
Hence the dimensions of the rectangle are 6inch and 4 inch.

Answer:
No
Step-by-step explanation:
Because if the coat is 20% with an additional 10% off that would equal 30% which is equal to the 30% off at the current store so they're both giving out the same deal
Answer:
No, because %30 is taking more off a higher number. Rather than only taking %20 off of it than the %10 is taking off an amount on a smaller amount resulting in it taking off less.
Step-by-step explanation:
$80 * 0.3 (%30) = $24
$80 - $24 = $56
$80 * 0.2 (%20) = $16
$80 - $16 = $64
$64 * 0.1 (%10) = $6.4
$64 - $6.4 = $57.6
