White raven [17]
The greatest common factor of the numbers is that which is the fused factors of all the numbers without the repetition of the common factors present in the given.
                          25·5·11 = 5·5·5·11
                          23·52·7 =23·2·2·13·7
Since, there are no repeated factors, the answer would be,
                                        5·5·5·11·23·2·2·13·7
The answer unfortunately is not among the choices.

Question 4
lawyer [7]

Answer:

18ft

Step-by-step explanation:

L = length

W = width

l = w + 2ft ; because the is 2 ft longer than width

The area of a rectangle is lw

You can take the first equation ( l = w + 2 ) and plug it in lw

like this: lw ---> (w+2)w = w^2+2w

then from the question you get: w^2+2w=19.25

you use the quadratic formula and get w = 3.5

then from the first equation, you get l = 3.5+ 2 so the length is 5.5

lastly, you use the perimeter formula: 2(l+w) so 2(9) = 18

so 18ft

You have 2,112 grams of a radioactive kind of mercury. How much will be left after 188 days if it's half-life is 47 days?
Anastasy [175]

Answer:

  • 132 g

Step-by-step explanation:

  • Initial amount = 2112 g
  • Time = 188 days
  • Half-life = 47 days

188 days / 47 days = 4 periods

<u>Mercury left after 188 days:</u>

  • 2112 * (1/2)^4 =
  • 2112* 1/16 =
  • 2112/16 =
  • 132 g

Complete the puzzle by clicking on the puzzle piece that contains equivalent expression.
Liono4ka [1.6K]

Answer:

 -5 when ...

Step-by-step explanation:

The rules of exponents can help you simplify the given product.

<h3>Rules</h3>

  (a/b)^c = (a^c)/(b^c)

  (ab)^c = (a^c)(b^c)

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

<h3>Application</h3>

  \left(\dfrac{x}{y}\right)^2(-x^2y)^3=\\\\\dfrac{x^2(-1)^3(x^2)^3y^3}{y^2}=-x^{2+2\cdot3}y^{3-2}=-x^8y

This expression does not match any of those offered.

When x=-1 and y=5, this becomes ...

  -(-1)^8(5)=\boxed{-5}
