Step-by-step explanation:
step 1
Find the volume of the water
The volume of the water is equal to

we have

substitute


step 2
Find the deep of the water, if the tank is returned to its horizontal position
(resting on its 60 cm × 100 cm base)
Now we have


substitute the given values

solve for H


therefore
The deep of the water would be 20 cm
After the change, the car is now moving faster than before.
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Ratio of sapphires to emeralds = 3:1
Let the number of sapphires be 3x.
Let the number of emeralds be 'x'.
According to question, if 6 emeralds are added, we get that

So, Number of sapphires = 3×3 = 9
Number of emeralds = 3
So, total emeralds would be 3+ 6 = 9.
Hence, option 'A' is correct.
Answer: 9.
Step-by-step explanation:
8 5/6 is a mixed number with a whole number and a fraction. We want to round to the nearest whole number without the fraction.
First, we convert the mixed fraction to an improper fraction or fraction like this:
((8 x 6)+5)/6 = 53/6
Then, we divide the numerator by the denominator from the previous step:
53/6 = 8.83
Now we have one decimal number. Round using the following rules:
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is.
.83 is .5 or higher. Thus, we add 1 to the left of the decimal point. 8 5/6 rounded to the nearest whole number is therefore the answer will be 9.
