During a typical shower, 17 gallons of water are used If Jana takes two showers a day what is the ratio of gallons used for one

olchik [2.2K]

Answer:

$x = \frac{1}{2}$

Step-by-step explanation:

The ratio of gallons used for one shower is obtained by dividing the total of gallons by the number of showers per day:

$n = \frac{17\,galllons}{2\,\frac{showers}{day} }$

$n = 8.5\,\frac{gallons}{shower}$

The ratio of gallons used for one shower to total gallons used is:

$x =\frac{8.5\,gallons}{17\,gallons}$

$x = \frac{1}{2}$

Perform the following operations and write the answers in radical form. Part A:√7+√3+√98−√18 Part B:3√5−3√11+2√121−3√90

Sveta_85 [38]

Answer:

$\sqrt{7}+\sqrt{3}+4\sqrt{2}$
$3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

Step-by-step explanation:

Part A ;

$\sqrt{7} +\sqrt{3} +\sqrt{98} -\sqrt{18} \\\\\sqrt{98}=7\sqrt{2}\\\sqrt{18}=3\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+7\sqrt{2}-3\sqrt{2}\\\\\mathrm{Add\:similar\:elements:}\:7\sqrt{2}-3\sqrt{2}=4\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+4\sqrt{2}$

Part B ;

$3\sqrt{5} - 3\sqrt{11} + 2\sqrt{121} -3\sqrt{90} \\\\2\sqrt{121}=22\\3\sqrt{90}=9\sqrt{10}\\\\=3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

iris [78.8K]

Answer:

K(3, 5)

Step-by-step explanation:

let K(x, y)

then x + 7 = 5*2 and y + 7 = 6*2 by the midpoint theorem.
