How to differentiate y=x^ln7 ?

Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6

Anuta_ua [19.1K]

Answer:

there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

Step-by-step explanation:

Given:

Number of pens = 171 pens

Number of pencils = 63

Number of erasers = 27

We need to number of each items in the bags.

Solution:

First we will find the largest number of gift bags that can be packed.

To find the the largest number of gift bags that can be packed we need to find the greatest common factor of these numbers.

So we will List the prime factors for each number:

$171 = 3 \times 3 \times 19\\\\63 = 3 \times 3 \times 7\\\\27 = 3 \times 3 \times 3$

From above we can say that;

The greatest common factor of three numbers = $3\times3=9$

Hence There would 9 gifts bag to packed this item.

Now To find the Number of item in each bag we will divide number of items from the number of gifts bag.

framing in equation form we get;

Number of pencils in each = $\frac{63}{9}=7\ pencils$

Number of pens in each bag = $\frac{171}{9}=19\ pens$

Number of eraser in each bag = $\frac{27}{9}=3\ erasers$

Hence there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

Solve: 3^x+1 + 3^x= 108

mash [69]

Answer:

x = 3

Step-by-step explanation:

${3}^{(x + 1)} + {3}^{x} = 108 \\ \\ {3}^{x} .3 + {3}^{x} = 108 \\ \\ {3}^{x} (3 + 1) = 108 \\ \\ {3}^{x} (4 )= 108 \\ \\ {3}^{x} = \frac{108}{4} \\ \\ {3}^{x} = 27 \\ \\ {3}^{x} = {3}^{3} \\ \\ \implies x = 3$
