Answer:

Adult tickets = 18

Children tickets = 25

Step-by-step explanation:

We can write 2 equations and solve:

let number of adult tickets be a and number of children tickets be c

Adult ticket cost is 8 and children cost is 5 and total money is 269, thus:

1. 8a + 5c = 269

Also, he sells seven more children's tickets than adult tickets, thus:

2. c - 7 = a

Now substituting 2 into 1, we can solve for c:

8a + 5c = 269

8(c-7) + 5c = 269

8c - 56 + 5c = 269

13c = 325

c = 325/13 = 25

Now using equation 2, we can solve for a:

c - 7 = a

25 - 7 = a

a = 18

So, 18 adult tickets and 25 children's ticket

To approximate the number of bees in a hive, multiply the number of bees that leave the hive in one minute by 3 and divide by 0.
AlekseyPX

Answer:

There are about 5,357 bees in the hive

Step-by-step explanation:

Let

x ----->  the number of bees that leave the hive in one minute

y -----> the approximate number of bees in a hive

we know that

The formula to calculate the approximate number of bees in a hive is equal to

y=\frac{3x}{0.014}

For x=25

substitute

y=\frac{3(25)}{0.014}

y=5,357\ bees

therefore

There are about 5,357 bees in the hive

Evaluate lim x=π/4(3x - tanx)​
Karo-lina-s [1.5K]

Answer:

 \lim_{x \to\frac{\pi }{4} } (3x-tanx) =  3(\frac{\pi }{4}  )

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that

         \lim_{x \to\frac{\pi }{4} } (3x-tanx)

  =  \lim_{x \to\frac{\pi }{4} } (3x) -  \lim_{x \to\frac{\pi }{4} }  tanx)

 = 3(\frac{\pi }{4} )+tan(\frac{\pi }{4} )

=  3(\frac{\pi }{4} )+ 1 )

=  3(\frac{\pi }{4}  )
