. Out of 40 pupils only 30 pupils submitted their project on time
Verizon [17]

Answer:

75 %

Step-by-step explanation:

To solve for the above question,

The percentage of pupils that submitted their project on time

= Number of pupils that submitted their project on time/Number of pupils × 100

Number of pupils that submitted their project on time = 30 pupils

Number of pupils = 40 pupils

= 30/40 × 100

= 75 %

The percent of the pupils that submitted their project on time is 75%

Find the GCF of the following monomials.<br><br> -50m4n7 and 40m2n10
Dima020 [189]

Answer:

Assuming you are asking for the Greatest Common Factor (GCF) of -50m^4n^7 and 40m^2n^{10} the answer is:

10m^2n^7

Step-by-step explanation:

To find the GCF we should first find the GCF of the coefficients 50 and 40 which is 10.

After factoring that out we need to take a look at the variable m. In monomial 1 we see that the highest exponent of m is 4 and in the second is 2. When finding GCF we take the smallest of the two exponents which is 2. Therefore the next part of our GCF monomial is m²

If we apply the same rule for n the smallest exponent is 7 resulting in the appending of n^{7} to the answer

After combining each of these GCF of 40 and -50 (10), m^4 and m² (m²), and n^7 and n^10 (n^7) the answer is:

10m^2n^7

16x 2 + 8x - 15 Mathematics?
Gala2k [10]
If you're factoring, your answer is

(4x - 3)(4x + 5)

You'll work it out this way:

16x^2 + 8x - 15

Since there's no GCF here, you multiply the first and third terms, giving you -240. Your next step is to find two numbers that have a sum of 8 and a product of -240. These numbers are 20 and -12. Plug those in and you've got:

16x^2 + 20x - 12x - 15

From here you divide it into two binomials. These are (16x^2 + 20x) and (-12x - 15).
When you take out the greatest common factors (4x and -3), they become:

4x(4x + 5) - 3(4x + 5)

Then you group what's outside of the parentheses together (4x - 3)
And bring what's inside of the parentheses down (4x + 5).
This brings your answer to

(4x - 3)(4x + 5)

The formula P=2(l + w)relates the perimeter P, in decimeters, with the length and width of a rectangle.
Degger [83]

Answer:

3. w=P/2-L

Step-by-step explanation:

<u>Given formula:</u>

  • P=2(l + w)

<u>Solving for w:</u>

  • P=2(l + w)
  • P/2 = 2(l + w)/2
  • P/2 = l + w
  • P/2 - l = l + w - l
  • P/2 - l = w
  • w = P/2 - l

<u>Correct answer choice is:</u>

  • 3. w=P/2-L

What is the rate of change from x = n to x = 2n?​
puteri [66]

Answer:

\dfrac{-8}{\pi}

Step-by-step explanation:

The rate of change of the function f(x) from point x_1 to point x_2 can be calculated using formula

\dfrac{f(x_2)-f(x_1)}{x_2-x_1}

Given

x_1=\pi\\ \\x_2=2\pi

From the graph of the function

f(x_1)=f(\pi)=4\\ \\f(x_2)=f(2\pi)=-4

So, the rate of change is

\dfrac{f(x_2)-f(x_1)}{x_2-x_1}=\dfrac{-4-4}{2\pi -\pi}=\dfrac{-8}{\pi}
