The billboard is not tall enough as the height is 27.5ft which is less than 30ft.
The comparison of two quantities having the same units is called as Ratio.
ratio between quantity a and b is represented by a:b .
In the given question
The bill board should have at least 30ft height.
Height of lady = 5 ft 6 inches
=5.5 ft ...( as 6inch=0.5ft )
If the height of the lady is 5.5ft shadow length = 7 feet
Since the units of height of lady and length of shadow is same .
hence ratio can be used ,
also given that length of billboard = 35 ft.
Let the height of the bill board = x ft
The above situation can be represented using ratio as
(height of lady) / (length of shadow of lady)=(height of billboard)/( length of billboard shadow)
Substituting the values we get
5.5/7=x/35
On solving further we get
(5.5/7)*35=x
5.5*5=x
x=27.5
The height of the billboard is 27.5 ft .
Since , it is given that the height of the bill board should be at least 30ft tall , and the height of the billboard is 27.5ft.
Therefore , the billboard is not tall enough as the height is less than 30ft.

Determine by composition whether f(x) = 3x + 18 and g(x)=x-6 are inverses of each other.
O No, f(g(x)) + X
O No, f(g(x)) = x
O Yes, f(g(x)) = g(f(x)) = x
O Yes, f(g(x)) = g(f(x)) * x
Thus, (x) = 3x + 18 and g(x)=x-6 are not inverses of each other.
Two function are inverse if they do undo or cancel each other, which means
f and g are inverse if
f(g(x)) = x and g(f(x)) = x
Here, f(x) = 3x + 18 and g(x)=x-6
Lets check by substituting the values in the formula
⇒ f(g(x))
⇒ f(x-6)
⇒ (3x + 18) - 6
⇒ 3x - 12
⇒ x = 4
g(f(x))
⇒ g(3x + 18)
⇒ 3(x-6) + 18
⇒ 3x - 18 + 18
⇒ 3x
⇒ x = 1/3
What is composition maths?A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

What time does the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday? United Airlines has a 3 hour 45 minutes flight.
At 17:30 the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday.
The time difference of two zone is -7-(-6) = -1
The shipment departs at 14:45 pm
flight took time = 3:45 min
adding the time = 14:45 + 3:45
= 18:30
So it arrived at Dallas at 18:30 according to Edmonton (GMT -7)
It arrived in Dallas according to Dallas (GMT -6) = 18:30 - 1 hour

What is time zone?
A time zone is a region where everyone adheres to the same standard time for social, business, and legal activities. Because it is simpler for regions that communicate often to maintain the same time, time zones frequently follow national borders and their subdivisions rather than strictly following longitude.
Coordinated Universal Time (UTC), which ranges from UTC12:00 to UTC+14:00, is used to determine all time zones. Most zones have full hour offsets, but some, like those in India, South Australia, and Nepal, have additional offsets of 30 or 45 minutes.

A rational number is any number that can be written as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not equal to zero. In other words, a rational number can be expressed as p/q, where p and q are both integers and q ≠ 0.
given that one fifth times w equals negative one eight
we have to find the value of w
one fifth = 1/5
one fifth times w = (1/5)* w
negative one eighth = - 1/8
now according to the question
one fifth times w equals negative one eight
(1/5) *w = -1/8

Students were asked how they travel to

travel by train.
Of these, 24% live more than seven miles
from their school. What percentage of the
students travel over seven miles to school
by train? Give your answer to 2 d.p.
the percentage of the students travel over seven miles to school by train is 9 %.
Let the total number of students be represented by variable x
now, 37 % of them travel by train.
So, we get that:
By train = 37 % of x
By train = 37 / 100 (x)
By train = 0.37 x
Now, 24 % of them lives 7 miles away from the school.
So, 7 miles away = 24 % of 0.37 x
= 24 / 100 ( 0.37 x )
= 0.24 ( 0.37 x)
= 0.09 x
In percentage:
= 9 %

$ _____________ at 4 %
$ _____________ at 13 %
The amount invested in the account that paid 4% interest is $2,600
The amount invested in the account that paid 13% interest is $1,500.
What are the simultaneous equations that represent the equation?a + b = 4100 equation 1
0.04a + 0.13b = 299 equation 2
Where:
a = amount invested in the account that paid 4% interest
b = amount invested in the account that paid 13% interest
How much was invested in each account ?
The first step is to multiply equation 1 by 0,04
0.04a + 0.04b = 164 equation 3
Subtract equation 3 from equation 2
0.09b = 135
b = 135 / 0.09

Mel and 5 friends went to the go-kart track. Four people rented helmets for $3 each. The total cost to
rent the helmet and to ride the karts was $75. What was the cost to ride the karts for each person?
The cost of a ride for an individual person will be $10.5
It is given that Mel and 5 friends went to ride which makes the Total number of people for the Ride will be 6. Also, Four of them rented Helmets for the rides each helmet cost $3. It is also given that the total cost of helmets and rides is $75. From this we get :
Total people = 6, Helmet cost = 4*3 = $12, and Total cost = $75
Taking the cost of a ride as 'x' we get the equation representing this statement:
=> 4*3 + 6x = 75 => 6x = 63
=> x = 10.5
We get value of x = $75.

The stoplights will change color after 720 seconds. at the same time again.
Given: Stoplights A and B alternate between changing colors every 45 and 80 seconds, respectively.
One copy of each of the unique components and the common factor make up the Least Common Multiple (LCM).
The least common multiple of 45 and 80 is the amount of seconds before they change color simultaneously once more.
Since 80 = 5 x 2 x 2 x 2 and 45 = 5 x 3 x 3 respectively

The missing number in the equation is 6.
Given,
The sum of 23/6 and five times a number = 13/6 subtracted from six times the number.
We can take the number as x.
Now, the equation is:
23/6 + 5x = 6x - 13/6
Cross multiply both sides:
(23 + (5x × 6)) / 6 = ((6x × 6) - 13) / 6
We get,
(23 + 30x) / 6 = (36x - 13) / 6
Cancel 6 from both sides:
Then,
23 + 30x = 36x - 13
Add 13 to both sides:
23 + 13 + 30x = 36x - 13 + 13
We get,
36 + 30x = 36x
Add -30x to both sides:
36 + 30x - 30x = 36x - 30x

Additional comment
Solving a system of three or more equations "by hand" often can be done by an ad hoc process. It can be done in systematic fashion using Gauss-Jordan reduction techniques, but that often gets messy. Similarly, Cramer's Rule can be used, but that math tends to involve more arithmetic operations than are really necessary.
Adding the first equation to the other two eliminates the y-variable and reduces the system to two equations in two unknowns.
(9x +y -3z) +(10x -y +2z) = (-9) +(8) . . . . adding [1] and [2]
19x -z = -1 . . . . simplified
(9x +y -3z) +(-10x -y +4z) = (-9) +(10) . . . . adding [1] and [3]
-x +z = 1 . . . . simplified
At this point, we could graph the two equations, or we can proceed algebraically.
Adding these two equations gives ...
(19x -z) +(-x +z) = (-1) +(1)
18x = 0 ⇒ x = 0
Using the second of the reduced equations, we find ...
-x +z = 1
0 +z = 1 ⇒ z = 1
And using the second of the original equations, gives us ...
10(0) -y +2(1) = 8
-y = 6 . . . . . subtract 2
y = -6 . . . . multiply by -1
Then the solution is (x, y, z) = (0, -6, 1), as above.

the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.
We are given that the selling price of a pick up item is given as:
Selling price = $ 18,760
Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.
The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:
Money = 4.5 % of $ 18,760
Money = 4.5 / 100 × $ 18,760
Money = 0.045 × $ 18,760
Money = $ 844.2
