Step-by-step explanation:
Answer:
The distance across the lake is 3.5 km
Step-by-step explanation:
Hypotenuse is divided in equal parts. Thus both sides are divided in the same proportion.
The number of each type Mika bought =x = 6.8 rolls; y= 2.2 rolls.
<h3>Calculation using ratio</h3>
The number of rolls of film Mika bought = 9 rolls
The number of rolls that had 36 exposures = x
The number of rolls that had 12 exposures = y
The total number of exposures = 36 + 12 = 48
To find the exposure by one roll = 48/9 = 5.3
If one roll = 5.3 exposure
x roll = 36 exposure
Make x roll the subject of formula,
x roll = 36/5.3 = 6.8 rolls
- If one roll = 5.3 exposure
y roll = 12 exposure
Make y roll the subject of formula,
y = 12/5.3 = 2.2 rolls
Therefore, the number of each type Mika bought = x = 6.8 rolls; y= 2.2 rolls.

Hi. Okay, #16 says write a decimal between 0.5 and 0.75. Then write it as a fraction in simplest form and as a percent.
write a decimal = I will pick 0.15 - now we need to write it as a fraction since the 5 is in the hundredths place our fractions would be:
15/100 = 3/20 (simplest form)
Now to change .15 to a percent we simply move the decimal two places to the right and add a % sign so. 15 = 15%
Question 17
How would you write 43 3/4% as a decimal
For this one, it is a lot easier than you think. The answer is 43.75. Let me tell you how...
To change 3/4 to a decimal, you are merely dividing the 4 into 3.00, hence the .75 and then just bring the 43 over. With problem like this that end in 1/4, 1/2, 3/4 just think of 4 quarters---1 quarter =.24, 2 quarters = .50, 3 quarters =.75
Question 16 answer is: .15, 15/100=3/20 and 15%
Question 17 answer is: 43.75
I hope this helps. If you have any questions, please don't hesitate to ask.
Take care,
