Answer:

3/2

Step-by-step explanation:

Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

NARA [144]

Answer: b. 70%

Step-by-step explanation:

Given : Nik logs the following hours meeting with clients (c) or doing other work (o) :

Mon: 6 c, 4 o

Tue: 8 c, 2 o

Wed: 9 c, 1 o

Thu: 7 c, 3 o

Fri: Off

The number of hours Nik spend with clients on Thursday = 7 [Number of corresponding to c is 7 in the table]

Total hours he spend in work on Thursday = 7+3 = 10

The percent of time Nik spent with clients on Thursday :

$\dfrac{\text{Number of hours he spent with clients}}{\text{Total works he work on Thursday}}\times100\\\\=\dfrac{7}{10}\times100=7\times10\%=70\%$

Hence, the Nik spent 70% of his time with clients on Thursday.

Thus , the correct option is b. 70%.

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,

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

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

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

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

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