Answers

Answer 1

Answer:

a₄ = 1.25

Step-by-step explanation:

Given that,

First term of GP, a₁ = 10

The common ration of GP, r = 0.5

The nth term of the GP is given by :

[tex]a_4=a_1r^{n-1}\\\\a_4=a_1r^3\\\\a_4=10\times (0.5)^3\\\\a_4=10\times 0.125\\\\a_4=1.25[/tex]

So, the fourth term of the GP is 1.25.

Question 4
There are 15 members in a bicycle club this fall. By next summer, Ming hopes the number of members will be 140% of this number. What is
Ming's goal for the number of members next summer?

Answers

Ming's goal for the projected number of members next summer is the product of percentage increase and the current number of members, which is 21

Given the Parameters :

Present number of members in club = 15

Expected percentage rise = 140%

The projected number of members next summer can be calculated thus :

Current number × Expected percentage rise

15 × 140%

15 × 1.4 = 21

Therefore, Ming expects to see the number of members rise to 21 next summer.

60d+65n=2800
50d+45n=2150

Answers

From the second equation we can find that d=43-(9/10)*n
we can put this equation into the first one,
So we have equation 60(43-(9/10)*n)+65n=2800
Solving that we get n=20
60d+65*20=2800
d=25

So the answer is d=25 and n=20

Ciara has a bag of 60 colored marbles. There are purple, green, and red marbles,. She empties the bag, sorts the marbles, and counts 11 purple marbles and 20 green marbles. She wants to write a ratio of the number of purple marbles to the number of red marbles. How can she find the number of red marbles without counting them?

Answers

Answer:

[tex]Red = 29[/tex]

Step-by-step explanation:

Given

[tex]Total = 60[/tex]

[tex]Purple = 11[/tex]

[tex]Green = 20[/tex]

Required

Number of red marbles, without counting

To do this, we simply subtract the sum of the purple and red marbled from the total marbles.

So, we have:

[tex]Red = Total - (Purple + Green)[/tex]

[tex]Red = 60 - (11 + 20)[/tex]

[tex]Red = 60 - 31[/tex]

[tex]Red = 29[/tex]

Step-by-step explanation:

2 + xi  + y + 3i = 6 + 8i

(2 + y) + xi + 3i = 6 +8i

(2 + y) + (x + 3)i = 6 + 8i

Compare real numbers

Step-by-step explanation:

Find the diagram attached

Complete Question:

In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?

Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y

y+y+104 = 180

2y = 180-104

2y = 76

y = 38degrees

Since <STR = y, hence the measure of <STR = 38degrees

A enjoying a new movie B) B learning about history C) C how a movie was written D knowing about countriesOh and here's the passage (if you read it, thanks for reading it).1If you liked last summers Merry Maids, youll love this seasons Lucky Flowersthe newest film from director Mike Willow. He is known all over the world of cinema for his odd method of storytelling. In this film, Willow does a fine job of directing the actors to seem real and genuine in their desires. The subject matter is quite different from anything else currently showing in movie theaters, but this movie makes an important point about happiness. Lucky Flowers is an outstanding success among Willows body of work. This coming-of-age story is the first in a new trilogy. In this film, a young poet named Jesse Germane travels to several places in Europe. He says he feels clogged and wants to find the perfect subject for his writing. Up until his international travels, Jesse has lived a rather boring lifeor so he thinks. While in Europe, Jesse learns several lessons about himself, literature, and the meaning of life. 3Dazzling vistas serve as the background for many of the scenes in the filma signature feature of Willows movies. One of the most memorable scenes in the film follows the lead character as he walks through the vast gardens of Versailles with his idol, writer Neil Dungeon (played by himself). During this exchange, one has to choose which part of the film to focus on: the amazing scenery or the fascinating dialogue between the two characters. In a perfect world, this movie would last twice as long. That way the audience could more thoroughly enjoy the work of the cast and crew. Thank goodness for DVDs, as this film definitely deserves a place on your living room shelf. 4In Italy, Jesse visits historical monuments and meets many famous artists. The camera sweeps from the rural countryside through the old romantic cities. Both locations inspire Jesse to write rhythmic verse. He uses whatever kind of paper lies close at hand. In one scene, Jesse scribbles a poem on his dinner napkin to the amusement of the other dinner guests. When Jesse isnt hunched over his desk writing poetry, hes penning letters to his family in America. His correspondence is spoken aloud over several scenes, read by the same fine actor who plays Jesse. In the end, in time to a loud symphony of music, Jesse realizes that the finest subjects in literature are the everyday relationships that make up our lives. He pens a poem in honor of living simply. The poem goes on to influence all sorts of readers. My only complaint in regard to this movie is about the point that everyone should be satisfied with his or her everyday life. This idea seems out of place with the main characters need to travel to the ends of the earth. Otherwise, Lucky Flowers is a surprisingly smart film that will entertain the whole family.once again thanks for reading it.here's question 2(when you answer put answer 2) if you're up for it.What does the author dislike about the movie?
