The distance on a map from Lynchburg to Houston is 5 in. The scale on the map is 1/2 in = 100 mi. What is the actual distance?

A) 100 mi

B) 10,000 mi

C) 1000 mi

Answers

Answer:

1,000 miles

Step-by-step explanation:

set up the equation as

100x = d

where x equals the number of half inches between two points on the map

and d equals the distance between those points in real life

5 inches = 10 half inches so, plugged in the equation looks like

100(10) = d

simplify it to

1000 = d

and bam, the real distance is 1,000 miles

C 1/2 an inch equals 100 miles.each inch equals 200 miles. So now you take 200×5 and you get 1000 miles

Answer:

[tex]372100[/tex]

Step-by-step explanation:

A number to the [tex]x[/tex] power represents [tex]x[/tex] amount of times the number is multiplied by itself. To the second power means that the number is multiplied by itself twice.

[tex][(20\times30)+10]^2 = 610^2[/tex] (first work on terms inside parentheses)

[tex]= 372100[/tex] ([tex]610^2 = 610\times 610[/tex])

A town has a population of 3000 and grows at 4% every year. To the nearest tenth of a year, how long will it be until the population will reach 4700?

Answers

Answer:

14.2 years

Step-by-step explanation:

The town grows 4% (0.04) every year.

3000 x 0.04 = 120, so the town gains 120 people every year.

The town needs 1700 more people to get to 4700.

So, 4700/120= 14.1666666667

That rounds up to 14.2 years.

One acute angle of a right triangle measures 35°. What is the measure of the other acute angle? ·

Answers

Answer:

Step-by-step explanation:

A right triangle always has one angle which is equal to 90 degrees. You have been given the second angle which is 35 degrees hence to get the second acute angle you do:

180 - (90+35)

= 55

Answer:

we have,,

the traingle having one actue angle is 35degree

i.e angle ACB be 35degree, AND

another one angle ABCis 90degree

Also, let angle Bac be x

now,,

x+35+90=180(being the sum of traingle)

or,x=180-125

or,x=55

therefore, the value i.e angle BAC be 55 degree.

at 10 am both buses leave the station together
work out the next time they will leave at the same time

Answers

Answer:

Step-by-step explanation:

Find the LCM of 30 & 20

30 = 2 * 5 * 3

20 = 2 * 2 * 5

LCM = 2 * 3 * 2 * 5 = 60

60 minutes = 1 hour

So, again at 10am both will leave at the same time

Answer:

11 am.

Step-by-step explanation:

That would be the LCM of 20 and 30 which is 60 minutes.

So the nexrt time will be 10.00 + 60 mins

= 11.00 am.
