William bought some tickets to see his favorite singer. He bought some adult tickets and some children’s tickets, for a total of

15 tickets. The adult tickets cost $30 per ticket, and the children’s tickets cost $20 per ticket. If he spent a total of $270, then how many adult and children’s tickets did he buy

Set x as adult tickets.
Set y as children's tickets.
x + y = 15
30x + 20y = 270
Solve for x in the first equation.
x + y = 15
x = 15 - y
Plug this into the second equation.
30x + 20y = 270
30(15 - y) + 20y = 270
450 - 30y + 20y = 270
450 - 10y = 270
-10y = -180
y = 18
If there is 18 childrens tickets, there should be -3 adult tickets.
This is impossible, and this impossible answer occured because the question is written wrong.
There are a total of 15 tickets
The smallest costing ticket is the childrens ticket, which costs 20$.
If he only bought children tickets, this would be 20x15 which is 300$.
300$ is over 270$, which makes the question impossible.

Which function represents a vertical stretch of an exponential function?
nika2105 [10]

Answer:

A. f(x)=3(\frac{1}{2})^x

Step-by-step explanation:

The options are:

A. f(x)=3(\frac{1}{2})^x\\\\B. f(x)=\frac{1}{2}(3)^x\\\\C. f(x)=(3)^{2x}\\\\ D. f(x)=3^{(\frac{1}{2}x)}

For this exercise it is important to remember that, by definition, the Exponential parent functions have the form shown below:

f(x) = a^x

Where "a" is the base.

There are several transformations for a function f(x), some of those transformations are shown below:

1. If  bf(x) and  b>1, then the function is stretched vertically by a factor of "b".

2. If   bf(x)  and 0, then the function is  compressed vertically by a factor of "b"

Therefore, based on the information given above, you can identify that the function that represents a vertical stretch of an Exponential function, is the one given in the Option A. This is:

f(x)=3(\frac{1}{2})^x

Where the factor is:

b=3

And 3>1

What’s the answer For E
Vika [28.1K]

Answer:

∠E = 146°

Step-by-step explanation:

  • an isosceles triangle has both two equal sides and two equal angles
  • the sum of the interior angles of a triangle is 180°
  • the measure of third angle = the sum of the interior angles - the sum of two angles

E = 180 - (71 + 71) = 146

∠E = 146°

The corporate team building event will cost $12 if it has three attendees if there are five attendees how much was a quaker team
Norma-Jean [14]

Answer:

Cost to arrange the event for 5 attendees will be $20.

Step-by-step explanation:

We have to solve this question by calculating the unit rates or unitary method.

Since cost to arrange corporate team building event for 3 attendees is = $12

Cost to arrange the event for 1 attendee will be = \frac{12}{3} = $4

Therefore, cost to arrange the event for five attendees will be = 5×4 = $20
