54 is 120% of what number? Explain please!

Nataly [62]

$\displaystyle \text{54 is 120\% of what number} \\ \text{is will be = } \\ \text{of will be } \cdot \\ \text{what number will be z} \\ ---------- \\ 54=120\% \cdot z \\ \\ 54= \frac{120}{100}\cdot z \\ \\\\ z \cdot \frac{120}{100}=54 \\ \\ \\ z=54 : \frac{120}{100} \\ \\ \\ z=54 \cdot \frac{100}{120} \\ \\ \\ z= \frac{5400}{120} =45$

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

$212=50t+70$

$50t=212-70$

$50t=142$

$t=2.84\ min$
