Answer:
Step-by-step explanation:
Q3.
If ΔGHI and ΔJKL are similar, then the sides are in proportion:
We have
JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.
Substitute:
<em> multiply both sides by 2</em>
Q4.
We must multiply the original length by a scale factor of 3/4:
Find how many oz she ate: 1/2 of 3 is 1.5. 3/4 of 3 is 2.25. 1/2 of 2 is 1. Add all of the oz: 1.5+2.25+1=4.75. She ate 4.75 oz :)
8degree is the right answer
Given:
The equation is:
To find:
The solution for the given equation to the nearest hundredth.
Solution:
We have,
Divide both sides by 3.
Taking ln on both sides, we get
![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 2.4.
![[\because \ln (90)\approx 4.4998]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20%2890%29%5Capprox%204.4998%5D)
Round the value to the nearest hundredth (two decimal place)
Therefore, the value of K is 1.87.

Place a dot on the 2nd line (4:05) on the timeline. Next, count each line by 5 as you leave until you count to 60 (by 5s), place a dot at 5:05 (one hour or 60 minutes). Now, count by 5s until you count to 45 and place a dot on 5:50. Thus, the answer is 1 hour and 45 minutes.
Answer: 1 hour and 45 minute
Yes, this is reasonable because he started at 4:05 pm and ended at 5:50 pm which is exactly 1 hour and 45 minutes later during the evening.
b) He finished in 1 hour and 45 minutes. One hour equals 60 minutes, thus, 60 minutes + 45 minutes = 105 minutes.
Answer: 105 minutes
{hint: start counting as you leave each dot do not count the dot which you start at)
