A submarine left Diego Garcia and traveledtoward St. Vincent. Three hours later acruise ship left traveling at 16 km/h in aneffort to catch up to the submarine. Aftertraveling for five hours the cruise shipfinally caught up. What was the submarine's average speed
Average speed of submarine is 10 km/h
Given information;
Cruise ship left after 3 hours
Speed of cruise ship = 16 km / hour
Time taken by cruise ship = 5 hours
Find:
Average speed of submarine
Computation:
Distance = speed × time
Distance cover by cruise ship = 16 × 5
Distance cover by cruise ship = 80 km
So,
Distance cover by submarine also 80 km
So,
Time taken by submarine = 5 + 3
Time taken by submarine = 8 km
Average speed of submarine = 80 / 8
Average speed of submarine = 10 km/h

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate
Answer:
26.13
Step-by-step explanation:
to find the area of a circle, it's pi*r squared:
pi*3squared=9pi
it's a semi-circle so you divide it by two=4.5pi
they are telling us to use 3.14 instead of pi, so it would be:
4.5*3.14=14.13
now we find the area of the triangle. And we use the formula, (height*base)/2:
6*4/2=12
now we add the sums together, which is:
12+14.13=26.13
For tax purposes, you may have to report the value of your assets, such as cars or refrigerators. The value you report
drops with time. "Straight-line depreciation" assumes that the value is a linear function of time. If a 1150 dollar
refrigerator depreciates completely in 9 years, find a formula for its value as a function of time, x, in years.
value =
dollars
Depreciation implies the rate at which an asset is written off per year. So that the required formula is: value = $1150 - $127.78x.
Depreciation of an asset is a simple way of writing off the asset with respect to its life span. Using straight line method, the formula for determining depreciation is:
Depreciation = [tex]\frac{Cost of asset - Residual value}{Time(years)}[/tex]
The residual value is the cost of the asset after its useful life.
Thus, in the given question, residual value of the asset = 0
So that,
Depreciation = [tex]\frac{Cost of asset}{Time}[/tex]
= [tex]\frac{1150}{9}[/tex]
Depreciation = 127.78
Thus, the depreciation of the asset is $127.78 per year.
Therefore since the asset depreciates by 127.78 every year, then the formula for its value as a function of time in years is:
Value = $1150 - $127.78x
where x is in years.
The required formula for the value is $1150 - $127.78x

Out of 350 students, 315 went
on the class field trip. What
percent of the students did
not go on the class field trip? Hurry! I need the answer asap!
Answer:
350-315=35
(35÷350)×100
=10%
Answer:
10%
Step-by-step explanation:
I subtracted the number of total students by the ones that went on the field trip.
350 - 315 = 35
35 students did not go on the field trip.
We can turn this into a fraction:
[tex]\frac{35}{350}[/tex]
[tex]\frac{35}{350}[/tex] = [tex]\frac{1}{10}[/tex]
[tex]\frac{1}{10}[/tex] = 10%
10% of students did not go on the class field trip.

B.) Moving left to right, the whole number stays the same and the hundredths decrease by 1.
C.) Moving left to right, the whole number stays the same, the tenths decrease by 1, and the hundredths decrease by 2.
D.) moving left to right, the whole number stays the same, the tenths stay the same, and the hundredths decrease by 2.
Answer:d
Step-by-step explanation:
The correct option is D.
Moving left to right, the whole number stays the same, the tenths stay the same, and the hundredths decrease by 2.
Given,
4.88 4.86 4.84 4.82
We need to see how the decimals are arranged with their place value.
What is the place value of decimal numbers?We have a decimal number:
13.579
The place value for each number are:
1 - tens
3 - ones
5 - tenths
7 - hundredths
9 - thousandths
We have,
4.88 4.86 4.84 4.82
We see that 4 in ones place remain the same.
8 in tenths place also remains the same.
The last digit in hundredths place is decreased by 2.
So we can say that,
Moving left to right, the whole number stays the same, the tenths stay the same, and the hundredths decrease by 2.
Thus the correct option is D.
Moving left to right, the whole number stays the same, the tenths stay the same, and the hundredths decrease by 2.
