Step-by-step explanation:
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.

Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).

What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, 20 yards of carpet weighs 30 pounds.
Here, 1 yard of carpet weighs = 30/20
= 1.5 pounds
34 yards of carpet weighs
= 34×1.5
= 51 pounds
Therefore, 34 yards of carpet weighs 51 pounds.

Since the triangle is a right angled, to find one side we should use the pythagoras theorem.
The longed side of the triangle is called the hypotenuse.
In equation form: x² + y² = z²
Therefore: 12² + x² = 13²
114+x²= 169
x²= 169-114
x²= 55
x = 7.41
Therefore the length of AC = 7.41

solve for x for the triangle
Step-by-step explanation:
90° + 2x-2 + x+5 = 180° [Angle sum property of triangle]
=> 90 + 2x + x - 2 + 5 = 180°
=> 3x + 93 = 180
=> 3x = 180 - 93
=> 3x = 87

Ms. Aluma is 165 cm tall. She wants to find her height in meters. Divide her height in centimeters by 100 to find her height in meters.
1.65 meters...........
Unit conversion is a way of converting some common units into another without changing their real value. Ms. Aluma is using the correct option.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.
Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,
Height of Ms. Aluma = 165 cm
= 165/100 meters
= 1.65 meters
Hence, Ms. Aluma is using the correct option.

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 12 cm, and the base has a
radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm
