Answer:
126 passengers from Trinidad.
Step-by-step explanation:
Given that,
On a BWIA flight, 2/3 of the passengers are from Trinidad.
Total passengers = 189
We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,
[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]
Hence, there were 126 passengers from Trinidad.

Step-by-step explanation:
i hope this helps, have a good day
The distance around a circle called Circumference.
Option C is correct.
What is circumference?The circumference of any shape in mathematics defines the route or boundary that surrounds the shape. In other terms, the circumference is also known as the perimeter, and it aids in determining the length of any shape's contour. The perimeter and area of a circle are two important dimensions of a circle, as we all know.
The circumference of the circle, also known as the perimeter of the circle, is the measurement of the circle's boundary.
The area of a circle, on the other hand, defines the region it occupies.
If we open a circle and draw a straight line through it, the length of the line is the circumference.
As, The Circumference (or) perimeter of circle = 2πR
Thus, the distance around a circle called Circumference.

A jewelry store offers its own brand of customizable charm bracelets. You are able to choose from 9
different charms for your bracelet.
How many different charm bracelets is it possible to create?
Answer:
It depends on the number of charms that your bracelet can have.
here we need to count the number of selections that we have, and the number of options for each one of these selections.
So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.
If each bracelet can have 2 charms then we have two selections.
For the first selection, we have 9 options,
If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:
C = 9*8 = 72
If we can select 3 charms, then:
first charm = 9 options
second charm = 8 options
third charm = 7 options
Total number of combinations = 9*8*7 = 504 combinations.
Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.

The flagpole is 17.2 feet long.
The measure of height of flagpole is 40.25 feet.
Given that, a flagpole casts a shadow that is 23 feet long.
What are heights and distances?Heights and Distances is a study about the applications of Trigonometry. It has many real-life applications, such as measuring the object’s height, depth of the object, the distance between two celestial objects etc. The formulas and the ratios of trigonometry are helpful in the study of heights and distances.
Jorge is 5.25 feet tall, and while standing near the flagpole he casts a shadow that is 3 feet long.
Let the height of the flagpole be x.
Now, tan θ=5.25/3 -------(I)
and tan θ=x/23 -------(II)
Equation (I)=(II), we get
5.25/3 = x/23
⇒ 3x=5.25×23
⇒ 3x=120.75
⇒ x=120.75/3
⇒ x=40.25 feet
Therefore, the measure of height of flagpole is 40.25 feet.

1)Apply the distributive property to solve the following.
(2 +19) x4
Answer:
Answer:
4x19+4x2 or 4x21
Step-by-step explanation:
If you multiply 4x19, you get 76. And if you multiply 4x2 you get 8. 76+8= 84
If you multiply 4x21 you get 84 also. Both of these answers are distributive property. (all it is, is different ways of solving the problem.)

Flying against the wind, an alrplane travels 4700 kilometers in 5 hours. Flying with the wind, the same plane travels 9520 kilometers in 7 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
i think this
Step-by-step explanation:
Let Va = the velocity of the airplane
Let Vw = the velocity of the wind
When flying with the wind:
(Va+Vw)*(4 hours) = 4000
4Va + 4Vw = 4000
4Vw = 4000 - 4Va
Vw = 1000 - Va
When flying against the wind:
(Va-Vw)*(7 hours) = 4200 km
7Va - 7Vw = 4200
Substitute 1000-Va for Vw and solve for Va:
7Va - 7(1000-Va) = 4200
7Va -7000 + 7Va = 4200
14Va = 11200
Va = 800 km/hr
Rate of wind:
Vw = 1000 - Va = 1000 - 800 = 200 km/hour

Answer:
a) zeros: -2/3, 6
b) x < -2/3, signs: -, -; sign of product: +
-2/3 < x < 6, signs: +, -; sign of product: -
x > 6, signs: + +; sign of product: +
c) solution: x < -2/3 ∪ x > 6
Step-by-step explanation:
a) The zeros of the product are the values of x that make either factor zero. (A product is only zero if one of the factors is zero.)
3x +2 = 0 ⇒ x = -2/3
x -6 = 0 ⇒ x = 6
The zeros of the quadratic are x = -2/3 and x = 6.
__
b) For values of x left of the left-most zero, both factors are negative. For values of x between the zeros, the left factor is positive and the right factor is negative. For values of x greater than the right-most zero, both factors are positive. That is, for large negative values of x, all factors are negative. Working left-to-right, each time a zero is crossed, one factor changes sign.
__
c) The solution is where the signs of the factors match:
x < -2/3 or -6 < x

What is the input value for which g(x) = 3 khan academy
Answer:
x = 9
Step-by-step explanation:
If g(x) = 3, that means that the output is three.
Outputs are y values.
Look at the graph. When y=3, the x = 9.
So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9
