If y varies inversely as x and y= 27when x =12 find x when y =-9

Answers

Answer 1
You would put 27 over 12 equal to -9 over x and cross multiply. You would come up with 27x = -108 and then divide both sides by 27 and come up with -4. X=-4

The area in square feet of a rectangular field is x^{2}-110x+2800. The width, in feet, ix x-40. What is the length, in feet?

Answers

Answer: I changed 2 items ({2} and ix), so review carefully. The length is (x-70) feet.

Step-by-step explanation:

Area = x^2 - 110x+2800

Width = (x-40)

Area = Width x Length

(x^2 - 110x+2800) = (x-40)*L

L = (x^2 - 110x+2800)/(x-40)

L = (x - 40)(x-70)/(x-40) Factor the numerator.

L = (x - 70) feet

(−14)÷(−34)

What is the quotient?

Enter your answer as a simplified fraction in the box.

Answers

Answer:

[tex] \frac{7}{17} [/tex]

Step-by-step explanation:

(-14) ÷ (-34)

14/34

= /17

The quotient of the division will be 0.41. And the solution of the division (−14) by (−34) would be 7/17  as a simplified fraction.

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

We need to divide the mixed fraction with integers, So

(-14) ÷ (-34)

The common denominator we can calculate as the least common multiple of the denominators then we get

14/34

= 7/ 17

= 0.41

Thus, the quotient of the division will be 0.41

Therefore, the solution of the division (−14) by (−34) would be 7/ 17  as a simplified fraction.

Which inequality below satisfies the solution set graphed on the following number line?

Answers

Answer:

D.

Step-by-step explanation:

The function must have the range  -3 to 5.

2x^2 - 4x - 30

= 2(x^2 - 2x - 15)

= 2(x + 3)(x - 5)

so the critical points are -3 and 5.

When x = -2 f(x) = 2* 1 * -7 = -14 <= 0

when x = 4 f(x) = 2 * 7 * -1 <= 0.

when  x= 0  f(x) < 0

So its the last option.

What are the range of all integers greater than 40 and less than 99 that are multiples of 3?

Answers

We want to find the total number of integers that are larger than 40 and smaller than 99 that also are multiples of 3.

The answer is 18.

We can solve this just by counting.

The first multiple of 3 larger than 40 is:

3*14 = 42

Now we know that 99 is also a multiple of 3 and that the multiples of 3 are separated by a distance of 3 units, then the total number of multiples of 3 between 42 and 99 is given by:

(99 - 42)/3 = 19

But we need to remove 1, because we used 99 and we have the restriction that our numbers must be "smaller" than 99.

Then we have a total of 18 multiples of 3 between 40 and 99.

Over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day what was the total change in the water level

A:10.55
B:-8.16
C:8.16
D:-10.55

Answers

If over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be:  C:8.16

Centimeter each day=-0.32

Days of changed in water level=25.5 days

Now let determine total change in the water level

Total change=25.5 days × (-0.32)

Total change=8.16 centimeter

Inconclusion if over 25.5 days a ponds water level changed by a average of -0.32 centimeter each day the total change in the water level will be:  C:8.16

What do you think the Harlem Cultural Festival meant to the Black community in 1969 and why? Cite evidence from the article below and add your own ideas in your response.The Chambers Brothers quintet launched into "Uptown (to Harlem)" on June 29, 1969. By then, 50,000 people had already made their way to the New York City neighborhood. For six Sundays, in fact, crowds at the Harlem Cultural Festival listened and danced to a who's who of Black music greats. It was a jubilant celebration of Black lives at the end of a turbulent decade."That concert was like a rose coming through cement," reflected one attendee.The 1960s had witnessed hard-fought wins for Black Americans. The civil rights movement had led to federal laws banning segregation. Another protected Black voting rights. Black cultural figures like writer James Baldwin and boxer Muhammad Ali had risen to national prominence. By 1969, the mottos "Black Pride," "Black Power," and "Black is Beautiful" were gaining momentum.The "cement" of racism, discrimination, and poverty continued to weigh heavily on the Black community, however. And the assassinations of Malcolm X in 1965 and Dr. Martin Luther King, Jr. three years later landed like cinder blocks. Dr. King's murder had triggered civil unrest in more than 100 U.S. cities. New York City was among them. It was against this backdrop that city leaders supported the 1969 Harlem Cultural Festival. Harlem has a long history as a center of Black culture. It was an ideal setting for a symbolic rose to bloom.The result was a series of free concerts in Mount Morris Park. They featured music for everyonegospel, jazz, blues, soul, funk, and rock. The pop group The 5th Dimension headlined the opening concert. The second Sunday was a gospel showcase starring the "Queen of Gospel Song," Mahalia Jackson. And the big names kept coming: Stevie Wonder, Gladys Knight and the Pips, Nina Simone, blues guitar master B.B. King, and more. There were also speeches by civil rights leaders. They called for Black unity and political action.Over the course of the festival, some 300,000 people packed the park. In sunshine and rain, people stood shoulder to shoulder. Parents wearing dashikis brought babies. Kids climbed trees for better views. Teens danced wherever they found room.The performers themselves knew they were part of something special. "I didn't expect a crowd like that," singer Gladys Knight recalled years later. "Something very important was happening. It wasn't just about the music."When it was over, though, the Harlem Cultural Festival faded from memory. TV producer Hal Tulchin had filmed the concerts. But when he contacted TV networks, the response was indifferent. Hours of footage sat in a basement for nearly 50 years. It was almost discarded. Then, musician Ahmir "Questlove" Thompson learned of the footage and turned it into an award-winning documentary. Summer of Soul was released in 2021.Now the festival has new life. Dorinda Drake, for one, is thankful. The concerts thrilled her when she was 18. Today, she remembers the overwhelming joy of the audience. "All the happy faces, the familiesthe crowds were just so happy," she told National Geographic. "And to see a bunch of happy Black faces like thatit was a beautiful thing."
