What is the solution to this equation? 3v(1/8-x)=-1/2

Answers

Answer:

v = −4/−24x+3

Step-by-step explanation:

Let's solve for v.

3v(1/8−x) = −1/2

Step 1: Factor out variable v.

v(−24x+3/8) = −1/2

Step 2: Divide both sides by (-24x+3)/8.

v(−24x+3/8)/−24x+3/8 = −1/2/−24x+3/8

v=−4/−24x+3

What is the length of the diameter to the nearest tenth of the circle?

Answers

Answer:

8.9 units

Step-by-step explanation:

Since, the circle is centered at origin. So, coordinates of center are (0, 0)Point (-4, - 2) is located on the circle. So, distance between (0, 0) & (-4, - 2) will be the radius of the circle.

[tex] \therefore \: r = \sqrt{ {( - 4 - 0)}^{2} + {( - 2 - 0)}^{2} } \\ \\ \therefore \: r = \sqrt{ {( - 4)}^{2} + {( - 2)}^{2} } \\ \\ \therefore \: r= \sqrt{16 + 4} \\ \\ \therefore \: r= \sqrt{20} \\ \\ \therefore \:2 r= 2 \sqrt{20} \\ \\ \therefore \:2 r=8.94427191 \\ \\ 2r = 8.9 \: \\ \\ diameter \: = 8.9 \: units[/tex]

Answers

Answer:

(a)2 1/4

(b)1 1/2

(c)1 1/18

(d)5 7/12

Step-by-step explanation:

(a) 11/3 - 17/12 = 44/12 - 17/12 = 27/12 = 9/4 = 2 1/4

(b) 33/10 - 18/10 = 15/10 = 3/2 = 1 1/2

(c) 41/9 - 7/2 = 82/18 - 63/18 = 19/18 = 1 1/18

(d) 47/6 - 9/4 = 94/12 - 27/12 = 67/12 = 5 7/12

Hope it helped :)

a) 3 2/3 - 1 5/12 we’ll convert to 12ths by multiplying the numerator and denominator of the first mixed number by 4.
3 8/12 - 1 5/12 = 2 3/12 = 2 1/4

b) 3 3/10 - 1 4/5 we’ll convert to 10ths by multiplying the numerator and denominator of the second mixed number by two.

3 3/10 - 1 8/10
Now we need to borrow from the three wholes to create more tenths
2 13/10 - 1 8/10 = 1 5/10 = 1 1/2

Or you can convert the first one to 33/10, and the second one to 9/5, which becomes 18/10.
33/10 - 18/10 = 15/10 = 1 1/2
Do whichever one makes more sense to your brain.

c) 4 5/9 - 3 1/2 we will convert both to 18ths.
4 10/18 - 3 9/18 = 1 1/18

d) 7 5/6 - 2 1/4 we will convert both to 12ths.
7 10/12 - 2 3/12 = 5 7/12

Every five years in March, the population of a certain town is recorded. In
1995, the town had a population of 4500 people. From 1995 to 2000, the
population increased by 15%. From 2000 to 2005, the population
decreased by 4%. What was the town's population in 2005? *
4527
4968
4995
5382

Answers

Answer:

So, the town had a population on 4,500 people in 1995. Then from 1995 to 2000, the population increased by 15%.

Convert 15% to a decimal by dividing it by 100. Then, the population in 1995 by this decimal.

15% ÷ 100 = 0.15

4,500 × 0.15 = 675

Now, add this to the population in 1995.

4,500 + 675 = 5,175

This means that the town had a population of 5,175 people in 2000.

To calculate the town's population in 2005, repeat the same steps we took to find the population in 2000, except this time we will subtract instead of add since the population DECREASED.

4% ÷ 100 = 0.4

5,175 × 0.4 = 207

5,175 - 207 = 4,968

FINAL ANSWER:

The town had a population of 4,968 in 2005.

Noha rides his bike 4 miles and andrew rides his bike 2 miles how long dose it take for them to meet up( there 15 miles away Question 5(Multiple Choice Worth 5 points)(MC)A Big YearBy Bob KowalskiWould you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. Most of North America participates in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record-holders and its commitment to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.This honesty comes from the fact that most people who want to break such a record know the greatest rewards are not necessarily in winning. Such rewards are in being able to commit a year of your life to do something you love. Rewards are found in seeing amazing, inspiring creatures like the California Condor or the Magnificent Frigate bird. Rewards also come in spending time with people who, like you, want to spend their time looking to the skies and trees for glimpses of emerald, crimson, or cerulean blue feathered jewels.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.Read this sentence from the article:You may be thinking that looking at birds is silly, but just think about the numbers of the recent record-holders and its commitment to get these numbers.
