Assignment due today Q-Q<br> 9 1/2=k/9

nikdorinn [45]

$\huge\mathfrak\blue{answer}$

$= q - \frac{q91}{2} = \frac{k}{9}$

$\blue{switch \: sides}$

$= \frac{k}{9} = q - \frac{q91}{2}$

$\blue{multiply \: 9 \: both \: sides}$

$= \frac{9k}{9} = 9q - 9 \: . \: \frac{q91}{2}$

$\blue{lastly \: simplify}$

$=\underline {k = 9q - \frac{{9q}^{91} }{2} }$

Before we can make the mashed potatoes, we need to boil some water. The water starts out at room temperature, 70° F, and increas

Karolina [17]

Answer:

Part a) $y=50t+70$

Part b) $t=2.84\ min$

Step-by-step explanation:

Part a) Create a linear equation

Let

t ----> the time in minutes

y ---> the temperature in °F

we know that

The linear equation in slope intercept form is equal to

$y=mt+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

The slope m is equal to

$m=50\° F\ per\ minute$

The y-intercept is

$b=70\° F$

substitute

$y=50t+70$

Part b) How many minutes until the water boils at 212° F?

For y=212° F

substitute in the linear equation and solve for t

$212=50t+70$

$50t=212-70$

$50t=142$

$t=2.84\ min$

Please please help!!!!!

serious [3.7K]

Answer:

$188\sqrt{2}-8\sqrt{5}$ feet

Step-by-step explanation:

Well the perimeter is the sum of all sides that means

P= lenght + width + lenght + width

P=2(lenght + width)

$P=2(2\sqrt{8}+3\sqrt{5}+45\sqrt{8}-7\sqrt{5} )\\\\P=2((2+45)\sqrt{8}+(3-7)\sqrt{5})\\\\P=2(47\sqrt{8}-4\sqrt{5})\\\\P=2(94\sqrt{2}-4\sqrt{5})\\\\P=188\sqrt{2}-8\sqrt{5}$
