Answer:
If two triangles are similar it means that all corresponding angle pairs are congruent and all corresponding sides are proportional. However, in order to be sure that two triangles are similar, you do not necessarily need to have information about all sides and all angles.

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.

i need help i'm about to cry lol
Answer and Step-by-step explanation:
The answer is the last answer choice.
g(x) = [tex]-(x + 2)^2 + 1[/tex]
We don't even have to look at the numbers to tell that this is the correct answer. We look at what is being placed there.
The equation for a transformed function is:
f(x) = [tex]a(x-h)^2 + k[/tex]
a determines the scale of the graph and whether the graph opens up or down.
h determines whether the graph shifts left or right.
k determines whether the graph shifts up or down.
We see that there is a -1 for a, which means the graph will be facing downwards. We see a 2 for where h is, but it really is a -2, and when it becomes a positive after simplifying, the graph will shift to the left.
k is a positive 1, so the graph will be shifted up 1 unit.
Thus, the answer is the last answer choice.

richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answer:
His gross pay for the month is $4,509.50
Step-by-step explanation:
The commission Richard Klein earns for oil change = 3.00%
The commission he earns for tune ups = 5.00%
The commission he earns for auto parts sales = 6.25%
The minimum salary he is guaranteed = $2,450.00
The amount he brought in last month includes;
1) $2,500.00 in oil changes
2) $4,500 in tune ups
3) Sold $28,200.00 in parts
The amount he earns last month in commission are;
3/100 × 2,500 = 75 in oil changes
5/100 × 4,500 = 225 in tune ups
6.25/100 × 28,200 = 1762.5 in parts sold
The total commission = 72 + 225 + 1762.5 = 2,059.5
∴ The total commission = $2,059.5
The amount he makes as salary = $2,450.00
Richard Klein's gross pay for the month = His total pay for the month
Therefore;
Richard Klein's gross pay for the month = $2,059.5 + $2,450 = $4,509.5

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)
Answer: $50.96
Step-by-step explanation:
The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.
The game cost this week before taxes will be:
= 59.95 - (15% × 59.95)
= 59.95 - (0.15 × 59.95)
= 59.95 - 8.9925
= $50.9575
= $50.96
The amount this week is $50.96
find out the total volume of cube _Edge Length =6 inches
Given:
The edge length of a cube = 6 inches
To find:
The volume of the cube.
Solution:
We know that, the volume of a cube is
[tex]V=a^3[/tex] ...(i)
Where, a is the edge length.
Substituting a=6 in (i), we get
[tex]V=(6)^3[/tex]
[tex]V=216[/tex]
Therefore, the total volume of the cube is 216 cubic inches.
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° ).

34 yards of carpet weighs 51 pounds.
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.

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
[tex] = > x = \frac{87}{3} [/tex]

What is the actual question?
Step-by-step explanation:
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
A package of mixed lettuce seeds contains 150 green lettuce seeds and 50 red lettuce seeds. What is the probability that a randomly selected seed will be a red lettuce seed? Write your answer as a percent.
Answer:
25%
Step-by-step explanation:
I used relative frequency approach
n(total number of seeds)= 150+50=200.
probability (selecting a red lettuce) = red lettuce divided by the total number of seeds.
probability (selecting red lettuce) = 50/200 = 0.25
in percentage, probability = 0.25*100= 25%✓
