Ms. Nellies

Mathematics
1 answer:
Marat540 [252]3 years ago

Answer:

the equation is incorrect

Step-by-step explanation:

Let u show the equation

The correct equation is 2\frac{1}{2} \div \frac{3}{8}

= 2 1/2 ➗ 3/8

= 5/2 ➗ 3/8

= \frac{ 5 \times 8}{2 \times 3}

= \frac{40}{6} \\\\ = \frac{20}{3}

= 6\frac{2}{3}

Hence, the equation is incorrect

Trey's Number line model is incorrect because it represents the expression

2\frac{1}{2} \div \frac{3}{8}

Ms. Nellies has enough vinegar for 6 groups of students as 2\frac{1}{2} \div \frac{3}{8}

= 6\frac{2}{3}

What is a coefficient ?
Ahat [919]
A coefficient is a number that is attached to a term.

For example:

3x² - 5x + 6 = 0                 

The coefficient of x² is 3.

The coefficient of x = -5. 

Hope this explains it.

Please help!! This is so confusing! 100 points!!
masya89 [10]

Answer:

The value of the expression given is:

  • 4

Step-by-step explanation:

First, you must divide the expression in three, and to the final, you can multiply it:

  1. [(3^8)*(2^(-5))*(9^0)]^(-2)
  2. [(2^(-2))/(3^3)]^4
  3. 3^28

Now, we can solve each part one by one:

<em>First part. </em>

  • 3^8 = 6561
  • 2^(-5) = 0.03125
  • 9^0 = 1 (Whatever number elevated to 0, its value is 1)
  • (6561 * 0,03125 * 1) = 205.03125

And we elevate this to -2:

  • 205.03125^-2 = 2<u>.378810688*10^(-5)</u> or <u>0.00002378810688 </u>

<em>Second part. </em>

  • 2^(-2) = 0.25
  • 3^3 = 27
  • 0.25 / 27 = 9.259259259 * 10^(-3) or 0.00925925925925

And we elevate this to 4:

  • 0.00925925925925^4 = <u>7.350298528 * 10^(-9)</u> or <u>0.000000007350298528 </u>

<em>Third Part. </em>

  • 3^28 = <u>2.287679245 * 10^13</u> or <u>22876792450000</u>

At last, we multiply all the results obtained:

  • 0.00002378810688 * 0.000000007350298528 * 22876792450000 = <u>3.999999999999999999</u> approximately <u>4</u>

<u><em>We approximate the value because the difference to 4 is minimal, which could be obtained if we use all the decimals in each result</em></u>.

Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. She decides to make the length of t
Andreyy89

Answer:

Width of the rectangular Park = 11 feet

Step-by-step explanation:

Given that the total length of the fencing is 62 feet. As has to be fenced around a rectangular park , it would be the perimeter of the rectangular park.

Also Shana wants the length of the run to be 20 feet. Hence the length of the park is 20 feet.

Here we will use the formula for perimeter to find the width of the run

Perimeter = 2(l+w)

62=2(l+w)

l+w = \frac{62}{2}

l+w=31

20+w=31

w=31-20

w=11

Hence the width of the run for her dog in park would be 11 feet.
