Answer: 55

Step-by-step explanation:

Let the number of cars washed last year be denoted as x.

This year, he washed 14 fewer cars than during last year's car wash. This will be denoted as x-14.

We can then represent them in an equation as:

x + (x - 14) = 96

2x - 14 = 96

2x = 96 + 14

2x = 110

x = 110/2

x = 55

Therefore, he washed 55 cars this year

Step-by-step explanation:

<h2><u>SIMPLIFY</u></h2>

$\frac{(2^{4} )^5}{2^{5} } \\$

<h3>now make use of the exponent rule :</h3>

$\frac{x^a}{x^b} = x^{a-b}\\$

$(\frac{(2^4)^5}{2^5} = (\frac{2^4}{2} )^5\\$

$\frac{2^4}{2} = 2^3$

= $(2^{3} )^5$

<h3>apply the exponent rule:</h3>

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

$2^{3*5} \\2^{15}\\$

= <u>32768</u>

Quotient of 1+i/3+4i?

NISA [10]

Answer:

$\dfrac{7}{25} - \dfrac{1}{25}i$

Step-by-step explanation:

I assume you are asking

$\dfrac{1 + i}{3 + 4i}$

although what you wrote means this

$1 + \dfrac{i}{3} + 4i$

Back to what I think is your problem:

$\dfrac{1 + i}{3 + 4i} =$

$= \dfrac{1 + i}{3 + 4i} \times \dfrac{3 - 4i}{3 - 4i}$

$= \dfrac{(1 + i)(3 - 4i)}{(3 + 4i)(3 - 4i)}$

$= \dfrac{3 - 4i + 3i - 4i^2}{9 - 16i^2}$

$= \dfrac{3 - i + 4}{9 + 16}$

$= \dfrac{7 - i}{25}$

$= \dfrac{7}{25} - \dfrac{1}{25}i$

The owner of a garden center pays $25 for each birdbath . She sells them for 15% more than she paid. Decide whether each express

strojnjashka [21]

Answer:

The selling price is $28.75b.

Step-by-step explanation:

There are no options given but I will represent the word problem mathematically.

Let b stand for all the birdbath. If the owner pays $25 for each, then he pays $25b.

Selling them for 15% more means, 15% of the cost price was added to the original price. Finding 15% of cost price we have:

15% x $25b = 0.15 x $25b = $3.75b.

Therefore, the selling price is given as

$25b + $3.75b = $28.75b.
