Mason, a hardwood flooring installer, needs to calculate the amount of hardwood flooring needed to cover a floor that's 33⁄4 yar
Aleksandr-060686 [28]

Answer:

20 5/8 yd^2

Step-by-step explanation:

width = 3 3/4 yd

length = 5 1/2 yd

First change both measurements to fractions.

3 3/4 = 3 + 3/4 = 12/4 + 3/4 = 15/4

5 1/2 = 5 + 1/2 = 10/2 + 1/2 = 11/2

area = length * width

area = 15/4 yd * 11/2 yd

area = (15 * 11)/(4 * 2) yd^2

area = 165/8 yd^2

165/8 = 20 remainder 5

area = 20 5/8 yd^2

Please answer correctly
Sonbull [250]

Answer:

The answer is 6 and -6

Step-by-step explanation:

The given equation is
x^2 - kx + 9 = 0 ... (1)

where a = 1. b = -k, c = a

since the equation (1) has equal roots

\Rightarrow b^2 - 4ac = 0 \newline\\\Rightarrow (-k)^2 - 4(1)(9) = 0\\ \newline\\\Rightarrow (k)^2 - 36 = 0 \newline\\\Rightarrow k^2 = 36 \newline\\\Rightarrow k = \pm 6

Hence volume of k = 6, -6

If the least value of n is 5, which inequality best shows all the possible values of n?
ZanzabumX [31]

Answer:

First option

Step-by-step explanation:

The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.

It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.

It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.

It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.

Your answer is the first option "n ≥ 5."

Hope this helps.
