an airline is trying to promote its new Boston to Atlanta flight. the usual price for this flight is $315.00. however the airline is offering a 40% discount until the end of the month. how much will the flight cost after the discount?
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{40\% of 315}}{\left( \cfrac{40}{100} \right)315}\implies 126~\hfill \underset{\textit{after discount}}{\stackrel{315~~ - ~~126}{189}}[/tex]
If usual price for flight is $315.00, the airline is offering a 40% discount until the end of the month. then the cost of the flight after the discount is 126.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that an airline is trying to promote its new Boston to Atlanta flight.
the usual price for this flight is $315.00.
The discount offered by airlines is 40%.
We need to find the cost of the flight after the discount.
Convert 40% to decimal by dividing with 100.
40/100=0.4
Now multiply 0.4 with 315
0.4×315
Zero point four times of three hundred and fifteen.
126
Hence, the cost of the flight after the discount is 126.

An angle measures 126° more than the measure of its supplementary angle. What is the measure of each angle?
Solution:
We know that:
A pair of supplementary angles always sum up to 180°This means that:
[tex]x + x + 126 = 180[/tex]Step-by step calculations:
Combine like terms and simplify:
[tex]x + x + 126 = 180[/tex]=> [tex](x + x) + 126 = 180[/tex]=> [tex]2x + 126 = 180[/tex]Subtract 126 both sides:
=> [tex]2x + 126 - 126 = 180 - 126[/tex]=> [tex]2x = 54[/tex]Divide 2 both sides:
=> [tex]\frac{2x}{2} = \frac{54}{2}[/tex]=> [tex]x = 27[/tex]This means that one angle is 27°. Let's find the other angle.
Finding the other angle:
[tex]27 + 126 = Other \space\ angle[/tex]=> [tex]153 \space\ = Other \space\ angle[/tex]Thus, the measure of the angles are 27° and 153°.
Answer:
27° and 153°
Step-by-step explanation:
Let "x" represent the angle.
We know that supplementary angles must add up to 180 degrees.
First, let's set up an expression for the supplement of the angle "x":
x+126
Now, let's use this information to set up an equation:
[tex]x+x+126=180[/tex]
Combine like terms:
[tex]2x+126=180[/tex]
Subtract 126 from both sides:
[tex]2x=54[/tex]
Divide both sides by 2
[tex]x=27[/tex]
The supplement would be:
[tex]x+126=27+126=153[/tex]
Therefore the measures of the two angles are:
27° and 153°
PLEASE HELP IM CONFUSED HOW TO FACTORISE THESE
WILL MARK BRAINLIEST
Answer:
These are all quadratics, where the x/y/a/b coefficient has been cancelled out. So it's like factorising a quadratic. What i mean by the x/y/a/b coefficient being cancelled out is for example y^2 - 1, becomes (y - 1)(y + 1). This is equal to y^2 - y + y - 1. You can see that - y + y = 0, to therefore it's not visible in the final equation, but it's there.
c) y^2 - 1 = (y - 1)(y + 1)
d) x^2 - 64 = (x - 8)(x + 8)
g) a^2 - 81 = (a - 9)(a + 9)
h) x^2 - y^2 = (x - y)(x + y)
k) 25 - x^2 = (5 - x)(5 + x)
l) 1 - b^2 = (1 - b)(1 + b)
o) x^2 - 400 = (x - 20)(x + 20)
p) 900 - y^2 = (30 - y)(30 + y)

A motor boat traveling with the current went 30mi in 3 h. Against the current, it took 5 h to travel the same distance. Find the rate of the boat in calm water and the rate of the current
Answer:
Speed of the boat is 9.4mph and the current is 15.4mph
Step-by-step explanation:
Rate= distance/ time
With current; rate= boat+ current= b+c
Against current; rate= boat - current = b- c
30=3(b+c)••••••••••••••eqn(1)
30=5(b-c)•••••••••••••••••eqn(2)
30=3b +3c••••••••••••••eqn(3)
30=5b-5c•••••••••••••••eqn(4)
Solve simultaneously
b=12mph
From eqn(3)
30=3b +3c
Divide both sides by 3, we have
10= b+c
If we make "b" the subject of the formula we have
b= (10-c)••••••••eqn(5)
Divide both side of eqn(4) by 5 we have
6=b-c••••••••eqn(7)
Substitute eqn(5) into 7
6= (10-c)-c
6= 10c-c^2
C^2-10c+6
C= 9.4 or 0.64
Substitute the highest value 9.4 into equation 7
6=b-9.4
b=6+9.4
b= 15.4
Speed of the boat is 9.4mph and the current is 15.4mph
