At the beginning of an experiment, there are 400 grams of contaminants. Each hour, three-fourths of the contaminants are filtered out.

Use the model to calculate the number of contaminants after the third hour of the experiment.

the answer is not 168.75 cause that is how much filtered/went away. I need to know how much is left after it was filtered.

Answers

Answer:

18.75

Step-by-step explanation:

first hour: 400×(1/4) = 100

second hour: 100×(1/4) = 25

third hour: 25×(1/4) = 18.75

A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark returned to the
same position. The team then measured the distance the wheel had rolled and found it to be 25 cm. To the nearest tenth, what is the area of
the wheel?

49.7 cm?
198.9 cm?
99.5 cm
19.6 cm?

Answers

Answer:

49.7 [tex]cm^{2}[/tex]

Step-by-step explanation:

Although it is hidden a bit, we are actually given the circumference of the circle, which is 25 cm.

We know that C = 2πr, so we can substitute variables to find the radius (r).

25 = 2πr

r = 25/(2π)

r = 3.9788... cm

The area of a circle is A = π[tex]r^{2}[/tex], so:

A = π [tex]3.9788^{2}[/tex]

A = 49.7359... [tex]cm^{2}[/tex]

A ≈ 49.7 [tex]cm^{2}[/tex]

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many fish did Jacob catch last year?

Answers

Answer:

12 fish

Step-by-step explanation:

You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.

[tex]\frac{30-6}{2}[/tex] = x

[tex]\frac{24}{2}[/tex] = x

12 = x

The number of planes in a year will be 219000 planes.

How to calculate the value in a year?

Rate demonstrates how many times one number can fit into another number. Rate contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Here, 150 planes arrive in 6 hours. The number of planes in a day which is 24 hours will be:

= 150 × (24/6)

= 600 planes.

The planes in a year will be:

= 600 × 365

= 219000 planes.

The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.

Does the cost of the chemical increase or decrease with time?

Group of answer choices

Increase

Decrease

Answers

9514 1404 393

Answer:

increase

Step-by-step explanation:

Your cost function appears to be an exponential function of the form ...

c(x) = (initial cost)·(growth factor)^x

When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).

The cost function increases with time.

Transition sentence: Gaines does this by showing how social norms, education, and justice system were like under the jim crow laws.Evidence from the book(CHART)Historical facts: laws that made the whites occupy a higher social rung than blacks.(from Niki browns article)2. Body Paragraph 1: Social normsA. Evidence from the book: In chapter 7 or 8(too hard to find)B. Historical facts: The justices argued that states could establish separate but equal facilities; if blacks and whites were treated equally, segregation would be allowed to stand. Yet, in almost all public facilitiesschools, hospitals, trains, restaurants, hotels, parks, cemeteries, the armed forces, and jury dutywhites received priority over African Americans. Following the decision, some institutions excluded African Americans altogether. This was normal back then.3. Body Paragraph 2: EducationA.Evidence from the book: On page 13 chapter 2: Yes Im the teacher, I said. And I teach what the white folks around here tell me to teach-reading, writing, and arithmetic.B.Historical facts: Thurgood Marshall, sought to dismantle segregation in Louisianas public schools. Tureaud believed that segregated education, and the meager resources allotted for African American children, perpetuated poverty and inequality across generations. With the assistance of the NAACP Legal Defense Fund, Tureaud sued the state of Louisiana for paying African American teachers lower salaries than their white counterparts.4. Body Paragraph 3: Justice SystemA.Evidence from the book: On pages 8 and 9 in Chapter OneB.Historical facts: Homer Plessy, an active member of a New Orleans civil rights organization, the Comit de Citoyens, bought a first-class ticket on a train and attempted to sit among whites. After he was arrested for breaking the law, Plessy sued the railroad company, his lawyers arguing that segregation denied him equal protection under the law as guaranteed by the Fourteenth Amendment. In 1896, however, the US Supreme Court upheld Louisiana law in its decision on Plessy vs. Ferguson. The reason they arrested Homer Plessy is because of the Jim Crow Laws applied to African Americans.5. Conclusion : In the book, A Lesson Before Dying by Ernest J. Gaines, it explains the everyday life and struggles in the 50s and 60s. Those years represent the Civil Rights movement. The book takes place in Louisiana, which was a state where African Americans were slaves and had little to no rights. The Civil Rights movement needed real heroes who could stand up for not only themselves but for others also. Jefferson, an African American boy who was in the wrong place at the wrong time, witnessed a murder but got blamed for it because he was black. In order to convince the jury that he is innocent, his lawyer called him a hog in from of the judge in the court, claiming that killing him on the electrical chair does nothing, just like if there was a hog in that chair. Jefferson died like a man, but those like Grant, who was a school teacher,are the real heroes, not only he stood up for Jefferson but also he represented the whole African-American community 1.) f -3(f2)(f -3) 2.)
