Nestor works at a garden center where he posts plants. It takes him 2 1/2 hours to pot 15 plants. How many plants can Nestor pot in 1 hour? * how many plants can he pot in 1 hour?

Answers

Answer:

Nestor can pot 6 plants in 1 hour.

Step-by-step explanation:

first lets convert 2 1/2 hours in mixed fraction form for better calculation

2 1/2 hours = (2*2 + 1)/2 = 5/2 hours

no of plants pot in  5/2 hours = 15

to find no. of plants pot in 1 hours lets

divide both side by 5/2

no of plants pot in  5/2/(5/2)  hours = 15/(5/2) = 15*2/5 = 6

no. of plants pot in 1 hour = 6

Thus, Nestor can pot 6 plants in 1 hour.

O (x -(4+131)

Answers

Answer:

just took the test and it's D on edge

Step-by-step explanation:

The required factor of polynomial function f(x) is (x - 4 + 13i) . Option D

Polynomial function f(x) has roots 4 - 13i and 5.
What must be a factor of f(x) is to determined.

What is a polynomial function?

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.


Since the root of the equation is given 5,  4 - 13i.
Now the factors can be given as (x - a)(x - b) for the polynomial function.


Implies (x - 5) and (x - (4-13i))


(x - 5) and  (x -4 + 13i) is the factor of the required polynomial function that has roots 4 - 13i and 5.

Thus, The required factor of polynomial function f(x) is (x - 4 + 13i) .

sashi weaves 25 baskets in 35 days how many days will it take for her to weave 110 baskets pls tell with steps

Answers

Answer:

Step-by-step explanation:

If Sashi weaves 25 baskets in 35 days, let's find out how long it takes her to weave 1 basket.

25 baskets = 35 days

To find how long one basket takes, divide 35 by 25

1 basket = 35/25 = 1.4 days

Next to find how many days it takes for her to weave 110, you just multiply by 110 since we know it takes her 1.4 days to weave 1 basket.

110 baskets = 1.4 times 110 = 154 days.

Luke solves this problem. He says that the difference is 416. 864 − 458 ________ Complete the explanation of the mistake Luke made. Luke regrouped 6 tens 4 ones as ? ten(s) 14 ones. He should have regrouped 6 tens 4 ones as ? ten(s) 14 ones. What is the correct difference? The correct difference is ___ .

Answers

Answer:

Luke regrouped 6 tens 4 ones as 6 tens 14 ones

He should have regrouped 6 tens 4 ones as 5 tens 14 ones

The correct difference is 406.

Step-by-step explanation:

First, we will complete the explanation,

For the difference,864 − 458, Luke got 416;

The explanation of the mistake Luke made is

Luke regrouped 6 tens 4 ones as 6 tens 14 ones

Such that, the difference of the ones (14 - 8) gives him 6 ones,

difference of the tens (6 - 5) gives him 1 ten

and difference of the hundreds ( 8 - 4) gives him 4 hundreds

Hence, his answer 416.

He should have regrouped 6 tens 4 ones as 5 tens 14 ones

So that, the difference of the ones (14 - 8) will give him 6 ones,

difference of the tens (5 - 5) will give him 0 ten

and difference of the hundreds (8 - 4) will give him 4 hundreds

Hence, he would have gotten 406.

The correct difference is 406.

Answers

Answer:

1/10

Step-by-step explanation:

it’s 1/10

we know because the fractions with whole numbers are obviously too big to be the smallest so we are left with 4 options,
2/3 cannot be the smallest because it is only one away from being whole, 3/8 is not the smallest because it’s only 5 away from being whole, and 1/4 is not the smallest cause it’s only 3 away from being whole. 1/10 in 9 away from being whole making it the smallest!

Write an expression for the perimeter of the triangle shown below: (4 points)

A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.


A 6.9x − 16

B 6.9x + 16

C 0.1x − 16

D 0.1x + 16

Answers

Answer:

The expression of the perimeter of the triangle is 0.1x - 16 ⇒ C

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its sides

Let us solve the problem

∵ The lengths of the sides of a triangle are:

0.5x + 93x-3.4x - 25

∵ The perimeter of the triangle = sum of lengths of its sides

∴ The perimeter = (0.5x + 9) + (3x) + (-3.4x - 25)

→ Add the like terms

∵ The perimeter = (0.5x + 3x - 3.4x) + (9 + -25)

→ Remember (+)(-) = (-)

∴ The perimeter = (3.5x - 3.4x) + (9 - 25)

∴ The perimeter = 0.1x + -16

∴ The perimeter = 0.1x - 16

The expression of the perimeter of the triangle is 0.1x - 16

By considering the discriminant, find the
value of the constant p such that the
following equation has equal/repeated
solutions.
4x2 + 8x + p = 0​

Answers

Answer:

p = 4

Step-by-step explanation:

A quadratic equation has equal/repeated solutions when a discriminant (Δ) is equal 0.

The formula of a discriminant (Δ) of equation

[tex]ax^2+bx+c=0\\\\\Delta=b^2-4ac[/tex]

We have the equation

[tex]4x^2+8x+p=0\to a=4;\ b=8;\ c=p[/tex]

substitute

[tex]\Delta=8^2-4\cdot4\cdot p=64-16p\\\\\Delta=0\iff64-16p=0[/tex]

subtract 64 from both sides

[tex]-16p=-64[/tex]

divide both sides by (-16)

[tex]\dfrac{-16p}{-16}=\dfrac{-64}{-16}\\\\p=4[/tex]

Here is the story and the questions are below it15 points each!!! plsIn South Dakota, Pine Ridge Indian Reservation is as big as Delaware and Rhode Island combined. It has some of the highest poverty rates in the United States. For three years, it has also hosted shows with music written for an orchestra by high school students."It's really a great thing to see these kids, and the pride that the reservation has in having these kids be stars," said David Gier. He is the music leader of the South Dakota Symphony Orchestra.The yearly music academy is one part of the Lakota Music Project. It's a program developed with the orchestra and musicians of the Lakota Native American tribe. The goal is to create cultural cooperation, teaching people about the Lakota and the orchestra."Through music, we are able to show a side of us that nobody gets to see," said Emmanuel Black Bear, a singer. He has been part of the Lakota Music Project since 2009. The native people have "a rich culture," he said. "I wanted to be a part of something where we could show the positive side of our people through music."Black Bear is bringing the Lakota Music Project to Washington, D.C. Native flute player Bryan Akipa and nine members of the South Dakota Symphony are also going. In October, Black Bear will perform at the Smithsonian's National Museum of the American Indian and at Washington National Cathedral. It is for a festival hosted by the PostClassical Ensemble. The goal is to show Native American influences on American music.Matching Two Different Types Of Music TogetherThe Lakota Music Project "deserves to be more widely known," said Joseph Horowitz. He is the PostClassical Ensemble's leader.The project began in 2005. It was soon after Gier started with the orchestra. He wanted to develop community programs, and he learned about tensions in his new community between Native and non-Native Americans.Gier approached local leaders and experts. One was Ronnie Theisz, a writer of books on Lakota culture. The two men talked about creating a project. An idea came one snowy evening at Pine Ridge. Some of the orchestra's musicians met with the Porcupine Singers, a drumming circle on the reservation. They played music for each other.Gier said the keeper of the drum talked about singing old songs and passing on tradition to younger people. It was the main thing both groups shared.There are plenty of differences, too. The timing of the two types of music is different, said Black Bear. "In the beginning, it was kind of difficult to match them together."Hearing The Music Instead Of Trying To Change ItThe first Lakota Music Project tour, in 2009, set themes for the concerts. Theisz became a leader on the project. He suggested grouping the concert around love and death, joy and sadness, with music from each culture. The second half had new works on Lakota themes. The Lakota Music Project is coming to Washington because of Horowitz's support of the Indianist movement. It was in the early 1900s. American composers wrote music based on Native American themes. Horowitz calls it "a major American cultural event that's been totally forgotten."From the Lakota point of view, however, the "Indianist" movement inappropriately uses Native American customs. It's based on a misunderstanding of Native traditions, they believe."Even when they loved to take source music from different Indian tribes," Theisz said of the Indianist composers, "they didn't appreciate it." They wanted to try to improve it, he said."We're trying to counter that," he said. "Hearing the real music is part of the project."The Lakota Music Project's focus remains on building bridges through music."It's just human connection," Gier said, "and feeling like we can make a difference."Question 1Refer to the Newsela article "The Lakota Tribe Wants to Educate People Through Music Project."Part AWhat is an implied idea in the article??A. The Lakota Music Project seeks to improve upon the music of different Indian tribes.B.
