Answer:

Step-by-step explanation:

Since the lines of hypotenuse are parallel,the triangles are similar

20/8 = x/18

cross multiplication

8x = 20x18

8x=360

x=45

"Find x" I managed to get -6/2c, I just want to double check if that is correct

Soloha48 [4]

- 6/2c is the correct solution

collect like terms : 3cx - cx = 2cx

hence 2cx = - 6

dividing both sides by 2c gives x = - 6/2c

SHOPPING you went to the mall with $80. You spent 25% of your money on a pair of shorts and 65% of the remainder on sandals. How

Troyanec [42]

$80*.25=$20 spent on shorts
$80-$20= $60

If K = {(x, y)|x - y = 5}, find the corresponding range of y for the domain {0, 2, 4}. {-5, -3, -1} {0, 2, 4} {5, 7, 9}

Aleks04 [339]

Answer:

The range = {-5 , -3 , -1} ⇒ first answer

Step-by-step explanation:

* In any equation the values of x are the domain of it and

the values of y are the range of it

* So to find the range of any equation substitute the values

of x (domain) in the equation to get the corresponding

values of y (range)

* In the problem

∵ K = {(x , y): x - y = 5}

∵ The domain is {0 , 2 , 4}

* Lets find K(0) , K(2) , K(4)

∵ K(0) = (0) - y = 5

∴ -y = 5 ⇒ Multiply both sides by -1

∴ y = -5

∵ K(2) = (2) - y = 5

∴ 2 - y = 5 ⇒ subtract 2 from both sides

∴ -y = 3 ⇒ Multiply both sides by -1

∴ y = -3

∵ K(4) = (4) - y = 5

∴ 4 - y = 5 ⇒ subtract 4 from both sides

∴ -y = 1 ⇒ Multiply both sides by -1

∴ y = -1

* The range = {-5 , -3 , -1}

A pig farmer owns a 20-arce farm and started business with 16 pigs. After one year, he has 421 pigs. Assuming a constant growth

IRISSAK [1]

Answer:

The correct answer is 206550 pigs.

Step-by-step explanation:

First of all you need to calculate the constant growth rate, which is given by the formula $p=((\frac{f}{s} )^{\frac{1}{y} } -1)*100$ where f is the value at the end of the year, s is the start value of that year, and y is the number of years.

From the excercise facts, we know that for 1 year (y=1), the final value is 421 (f=421), and the start value is 16 (s=16). Replacing them in the formula we get : $((\frac{421}{16}) ^{\frac{1}{1} } -1)*100 = 2531.25$ So, the constant growth rate equals 2531.25.

Next, we have to multiply the starting amount of pigs times the constant growth rate times the amount of time that passed to get the final quantity of pigs. This would be $16*2531.25*5.1$ and this gives us a total amount of 206550 pigs.

Have a nice day.
