Answer:
6 ft
Step-by-step explanation:
Given that:
Length of rectangular banner = 18 ft
Total trim of banner available = 48 ft
To find:
Possible widths of the banner = ?
Solution:
Maximum trim available of the banner around the entire border of the banner = 48 ft
i.e. we are given the total perimeter of the rectangular banner.
Formula for perimeter of a rectangle is given as:
[tex]Perimeter = 2 \times (Length + Width)[/tex]
Putting the values of perimeter and length to find the value of width.
[tex]48 = 2 \times (18 + Width)\\\Rightarrow 48 =36+2 \times Width\\\Rightarrow 2 \times Width = 48-36\\\Rightarrow 2 \times Width = 12\\\Rightarrow \bold{Width = 6\ ft}[/tex]
So, width possible is 6ft.
Given the function f(x) = -x^2 +7x + 6, find the interval(s) in which f(x) is decreasing.
Answer:
Step-by-step explanation:
f'(x)=-2x+7
f(x) is decreasing if '(x)<0
so -2x+7<0
or 7<2x
or 2x>7

Use the diagram below to find the value of x
{NO} =17
{NP} =5x-6
Answer : The value of 'x' is 8.
Step-by-step explanation :
As we are given that :
NO = 17
NP = 5x - 6
From the given diagram we conclude that NO and OP are equal and RO and OQ are equal. That means,
NO = OP and RO = OQ
That means,
NO = OP = 17
And we know that:
NP = NO + OP
So,
5x - 6 = 17 + 17
5x - 6 = 34
5x = 34 + 6
5x = 40
x = 8
Thus, the value of 'x' is 8.

How do I do? What is the answer and why
Answer:
Step-by-step explanation:
∠ADE = 74 {Vertically opposite angles are equal}
∠AED + 127 = 180 {Straight line }
∠AED = 180 - 127
∠AED = 53
In ΔADE,
∠DAE + ∠AED + ∠ADE = 180 {angle sum property of triangle}
∠DAE + 53 + 74 = 180
∠DAE + 127 = 180
∠DAE = 180 -127
∠DAE = 53
Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil. Find the oil in the third tanker
Step-by-step explanation:
It is given that, three oil tankers together contain 37 5/7 litres of oil.
Total volume of oil is [tex]\dfrac{264}{7}\ L[/tex]
If two tankers have 11 3/14 litres and 12 3/7 litres of oil.
Oil in first tanker is [tex]\dfrac{157}{14}\ L[/tex]
Oil in second tanker is [tex]\dfrac{87}{7}\ L[/tex]
Oil in first and second tanker is :
[tex]\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L[/tex]
Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )
[tex]=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L[/tex]
Hence, this is the required solution.

two complementary angles have a difference of 36°. Find the measure of each angle. (Complementary angles are angles that add up to 90°) Show ur work
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:
[tex]a+b=90[/tex]
And we are told their difference is 36. Therefore:
[tex]a-b=36[/tex]
Solve for the system of equations. Add b to both sides in the second equation:
[tex]a=b+36[/tex]
Substitute this into the first:
[tex](b+36)+b=90[/tex]
Combine like terms;
[tex]2b+36=90[/tex]
Subtract 36:
[tex]2b=54[/tex]
Divide by 2:
[tex]b=27[/tex]
So, b is 27 degrees.
Use the second equation again:
[tex]a-b=36[/tex]
Now that we know b is 27, substitute:
[tex]a-27=36[/tex]
Add 27 to both sides:
[tex]a=63[/tex]
So, a is 63 degrees.
And we're done :)
Answer:
27 and 63
Step-by-step explanation:
x - y = 36
x + y = 90
add the equations together
2x = 126
x = 63
substitute x for x in the first equation
63 - y = 36
y = 27

Answer:
1. I= $36, NB = $336
2. R = 5%, NB = $517.50
3. T= 5 YEARS, NB = $612.50
4. P= $675, NB = $783
Step-by-step explanation:
1. p= 300, r=3% t=4year
I= p*r*t
i= 300 * (3/100) * 4
i = 300 * 0.03 * 4
i = 36
New Balance = 300+36 = $336
2. r = (i*100)/(p*t)
= (67.50*100)/(450*3)
= 6750/1350
= 5%
New Balance =450+67.50 = $517.50
3. t= (i*100)/(p*r)
= (112.50*100)/(500*4.5)
= 11250/2250
=5
New Balance = 500+112.50 =$612.50
4. p= (i*100)/(r*t)
= (108*100)/(8*2)
= 10800/16
= $675
New Balance = $675+$108 = $783
