the value of f(g(3)) ?

A.) 2
B.) 3
C.) 5
D.) 6

Answers

Answer:

B. 3

Step-by-step explanation:

Start with the inside brackets where we have g(3). As seen, g(3) is given to be =2 so g(3) inside the bracket is now replaced with 2, giving us f(2). F(2) is given as 3, therefore the answer is B. 3

Convert 32,190 inches /year to yards

Answers

Answer:

2.4 yards a day

Step-by-step explanation:

32,190 inches = 894.167 yards

894.167 / 365 = 2.4 yds/day

The conversion of 32,190 inches /year to yards/day yields: 2.4 yards/day

To convert 32190 inches/year to yards per day;

We must first find the conversion factor of inches to yards and

We must also find the conversion factor of years to days.

In essence, since 1 inch = 0.0278 yards.

Therefore, we have;

32190 inches/year = 32190 × 0.0278 yards/year.

= 894.88yards/year.

However, 365 days make one year;

Therefore,

894.88 yards/year = (894.88/365) yards/day.

= 2.4 yards/day.

Answer:

105

Step-by-step explanation:

LN = 6x

LN = LM + MN ➡ LN = 4x + 8 + 27 so 6x = 4x + 8 + 27

2x = 35 and x = 17.5

6 × 17.5 = 105

Answer:

105

Step-by-step explanation:

4x+8+27=6x

subtract 4x from both sides you get 35 = 2x

divide and get x= 17.5

you know LN = 6(x), so substitute 17.5 in for x and you get 6(17.5)= 105

Eating on campus The director of student life at a small college wants to know what percent of students eat regularly in the cafeteria. To find out, the director selects an SRS of 300 students who live in the dorms. Describe how undercoverage might lead to bias in this study. Explain the likely direction of the bias.

Answers

Answer:

Well, in this case all the students selected live in the dorms, so it is actually likely that they eat in the cafeteria regularly.

For example, a student that lives in a house (with family, friends, etc) may have access to eat in his own place or may have larger economic freedom, so maybe they go and eat out. In this group, you may find that the probability for a randomly selected student eats in the cafeteria regularly may be smaller than in the group of the students that live in the dorms.

So the sample will be biassed towards eating regularly in the cafeteria.

The altitude a ( in feet) of a plane t minutes after lift off is given by a=3400t+600
How many minutes after liftoff is the plane at an attitude of 21,000 feet?

I need help understanding this ASAP PLZ!!!

Answers

Answer:

  6 minutes

Step-by-step explanation:

'a' in the formula represents altitude in feet. You are told the altitude is 21000 feet, so put that into the formula:

   21000 = 3400t +600

You can solve this for t:

  20400 = 3400t . . . . . subtract 600 from both sides

  6 = t . . . . . . . . . . . . . . . divide both sides by 3400

The problem statement tells you that t represents minutes after lift off, so this solution means the altitude is 21000 feet 6 minutes after lift off.

The question is asking for the number of minutes after lift off that the plane reaches an altitude of 21000 feet, so this answers the question directly:

  The plane is at an altitude of 21000 feet 6 minutes after lift off.

16. Rahul cycles at a speed of 6km/hr to reach school in 20 minutes. What should his
speed be if he wants to reach school in 15 minutes?​

Answers

Step-by-step explanation:

Distance to school = (6km/h)(1/3h) = 2km

2km in 15 minutes = 8km in 60 minutes.

Hence his speed should be 8km/h.

An object is moving at a speed of 4 meters per month. Express this speed in inches

per hour. Round your answer to the nearest hundredth.

*Note: you must use these exact conversion factors to get this question right.

Distance / length

Time

1 foot (ft) = 12 inches (in)

1 minute (min) = 60 seconds (sec)

1 yard (yd) = 3 feet (ft)

1 hour (hr) = 60 minutes (min)

1 mile (mi) = 5280 feet (ft)

1 day (day) = 24 hours (hr)

1 meter (m) = 100 centimeters (cm)

1 week (week) = 7 days (days)

1 kilometer (km) = 1000 meters (m)

1 month (month) = 30 days (days)

1 inch (in) = 2.54 centimeters (cm)

1 year (year) = 365 days (days)

1 foot (ft) = 0.305 meters (m)

1 mile (mi) = 1.609 kilometers (km)

Answers

Answer:

0.22inches/hour

Step-by-step explanation:

Given the speed of an object to be 4metres/month, we are to express the speed in inches/hour.

First we will need to convert 4meters to inches

From the conversion factors given,

1 foot (ft) = 0.305 meters (m)

x ft = 4metres

cross multiply

x * 0.305 = 4*1

x = 4/0.305

x = 13.115ft

4 metres = 13.115ft

Then we will convert 13.115ft to inches

From the conversion factors,

1 foot (ft) = 12 inches (in)

13.115ft = y

cross multiply

y = 13.115*12

y = 157.377 inches

Hence 4 metres = 157.77inches.

For 1 month to hour

First we need to convert month to days and from the conversion factor

1 month = 30 days

Next is to convert 30days to hours

Since 1 day = 24hours

30days = z

z = 30* 24

z = 720hours

Hence 1 month = 720hours

On converting 4metres/month to inches/hour

4metres/month = 157.77inches/720hours

4metres/month = 0.219inches/hour

Hence the speed of the object in inches per hour to the nearest hundredth is 0.22inches/hour

An average African elephant weighs about 9,072 pounds. How is this number written in scientific notation?

Answers

Answer:9.072×10³

Step-by-step explanation:

A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer

9072 is more than 10

So 9072÷10=907.2

Still 907.2 is more than 10

So 907.2÷10=90.72

Still 90.72 is more than 10

So 90.72÷10=9.072

9.072 is less than 10

We divided 9072 by 1000 and 1000 as a power of ten is 10³

So the answer is 9.072×10³
