A student used the proportion n/100 = 5/26 to find 5% of 26. What did the student do wrong?​

Answers

Answer 1

Given:

A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.

To find:

The student's mistake.

Solution:

Let 5% of 26 be n. Then,

[tex]n=\dfrac{5}{100}\times 26[/tex]

On dividing both sides by 26, we get

[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]

So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.

Zx and Zy are supplementary angles. Zy measures 142º.
What is the measure of Zx?

Answers

Answer:

Supplementary angles means the sum will be 180 degrees. So since Zx = 142 degrees, allow: 180 = 142 + Zy. So, 180 - 142 = 38 degrees = Zy.

Round 59.378 to the nearest hundredth.

Answers

Answer:

59.38

Step-by-step explanation:

In the number 59.378, "7" is in the hundredth place. So, we need to round it according to the 7. Anything to the left of 7 doesn't need to be rounded. If we round the thousandths place, 8, up to 7, we get 59.38

59.378 rounded to the nearest hundredth would be 59.38

3x2 − 8x + 4

Answers

Answer:

(3x - 2) (x - 2)

Step-by-step explanation:

im smart

First multiply 3 and 4 to get 12. Now, we must get two numbers that multiply to 12, but also add to -8. The answer is -6 and 2.

Now rewrite this expression as “3x^2-6x+2x+4.

Now, group together each set of two terms and find the GCF of each. The GCF of 3x^2 and -6x is -3x. The GCF of 2x and 4 is 2.

Now, divide each group by the GCFs and place them next to each other. You should get -3x(x+2)+2(x+2). We know this is correct because the parentheses match.

Now, rewrite the duplicate factors as one, and group together what is outside the parentheses. The final answer is...

(-3x+2)(x+2).

To check, you can double distribute (FOIL) to see if it matches the original expression.

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

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.

Answer:

Step-by-step explanation:

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

-39 < 5x + 36

Subtract 36 from both sides:

-75 < 5x

5x > -75

Divide both sides by 5:

x > -25.

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

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]
