Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday

= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold = 2 times the number of adult tickets sold on Friday

= 1,678 x 2 = 3,356

Children's Tickets sold = 3 times the number of children's tickets sold on Friday.

= 976 x 3 = 2, 928

So, the total number of tickets sold on Saturday

= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 + 6, 284 = 8,938

Hence, total number of tickets sold over these two days is 8,938.

An airplane flying at 650 miles per hour has a bearing of 54. After flying for 1.5 hours, how far north and how far east will th

PtichkaEL [24]

Answer:

627 miles north

747 miles east

Step-by-step explanation:

Bearing angles are measured east of north, so in (N, E) coordinates, the final position of the plane is ...

(1.5 h)(650 mi/h)(cos(50°), sin(50°)) = (975cos(50°), 975sin(50°)) mi

= (626.72, 746.89) mi

The plane will be 627 miles north and 747 miles east of its point of departure.

The table shows the outputs, y, for different inputs, x:

quester [9]

Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.

Part B:
When x=6 in the input-output table, y=6 as well. When x=6 in the relation f(x)=2x+16, f(x)=2(6)+16=28. The equation has a greater value when x=6.

Part C:
Set f(x) equal to 40 in the equation:
40=2x+16
Solve for x:
2x=24
x=12
x=12 when f(x)=40

Find the area of the figure.

madreJ [45]

answer:

4.5m²

explanation:

1. <u>find area of the circle</u>

A(circle)=πr²

A=π(2.3²)

A=16.62m²

2. <u>find area of the square</u>

the diameter of a circle is twice its radius. when you multiply 2.3 by two, you get 4.6. since the circle reaches to the sides of the square, the diameter is also the length of a side on the square.

A(square)=s²

A=4.6²

A=21.16m²

3. <u>subtract the two areas</u>

to find the area of the shaded sector, we need to subtract the area of the circle from the area of the square.

A(shaded)=21.16-16.62

A=4.54097487m²

(be sure to round as necessary)
