K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids

x+y=11
13.5x+8.25y=111.75

Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get

13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives

5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7

(3.2 * 10000000) -3

The exponents distribute over factors:

$(ab)^c = a^c \times b^c$

so, you have

$(3.2 \times 10^6)^{-3} = 3.2^{-3} \times (10^6)^{-3}$

Let's focus on each factor: applying the definition of negative exponents, you have

$3.2^{-3} = \cfrac{1}{3.2^3} \approx 0.03$

While for the power of 10, you can use the following rule

$(a^b)^c = a^{bc}$ to write

$(10^6)^{-3} = 10^{6\cdot (-3)} = 10^{-18}$

So, the expression evaluates to

$0.03\times 10^{-18} = 3\times 10^{-20}$

David says he has 2/3 of a pipe length left, while Don says he has 11/16 of a length left. Which person has the longest section

Kruka [31]

Answer:

Don

Step-by-step explanation:

1. We make the fractions have common denominators so it is easier to compare them. We can do this buy multiplying 2/3 by a factor of 16, so it becomes 32/48. For 11/16, we multiply by a factor of 3 so it becomes 33/48. It is now apparent that Don has the longer pipe.
