Answer:

x = 48°

Step-by-step explanation:

The sum of angles on a line is 180°.

The angles 42°, 90°, and x° lie on the same line.

42 + 90 + x = 180
x + 132 = 180
x = 48°

TRUE OR FALSE: A fraction of something is always equal to a fraction of another something

Mice21 [21]

Answer:

FALSE

Step-by-step explanation:

$\frac{x}{y}$ and $\frac{y}{x}$ are not equal.

If we assign numbers to both variables, for example x=1 and y = 2, we get:

$\frac{1}{2}$ $\neq$ $\frac{2}{1}$ . This shows that .5 is not equal to 2, therefore a fraction of something (x) is not always equal to a fraction of another something.

Hernando ate 2/8 of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told them to share it equally

vladimir2022 [97]

For this case we have that if Hernando ate pizza $\frac {2} {8}$ we have left:

$\frac {8} {8} - \frac {2} {8} = \frac {6} {8}$

Those $\frac {6} {8}$ pizza must be distributed equally among 6 people, then:

$\frac {\frac {6} {8}} {6} = \frac {6 * 1} {6 * 8} = \frac {1} {8}$

So, to each friend corresponds $\frac {1} {8}$ of pizza

ANswer:

To each of the 6 friends corresponds $\frac {1} {8}$ of pizza

A thermometer is taken from an inside room to the outside, where the air temperature is 20° f. after 1 minute the thermometer re

fomenos

The change in the temperature is proportional to the difference in temperatures. Let's call the initial temperature of the room and the thermometer $E_0$ and the current temperature $E(t)$ where $t$ is the elapsed time in minutes. The outside temperature is 20 F.

Newton's Law of Cooling:

$E(t) - 20 = (E_0 - 20) e^{- k t}$

We're given $E(1)=70 \textrm{ and } E(5)=45$

$70-20 = (E_0 - 20) e^{-k}$

$45-20 =(E_0 - 20) e^{-5k}$

Dividing,

$\dfrac{50}{25}=e^{4k}$

$k = \dfrac 1 4 \ln 2$

Now,

$E(t) - 20 = (E_0 - 20) e^{- k t}$

$E_0 = 20 + (E(t) - 20)e^{k t}$

$E_0 = 20 + (E(1) - 20)e^{k}$

$E_0 = 20 + (70 - 20)e^{\ln 2/4}$

$E_0 = 20 + 50 \cdot 2^{1/4} \approx 79.46 \textrm{ degrees F}$
