It would take john 6 hours to paint a room by himself. It would take Tom 18 hours to paint the same room by himself. Of john and tom work together, each at his individual rate, how many hours will it take the to paint the room.

Answers

Answer 1

Answer:

12 hrs

Step-by-step explanation:

6+18 =24

24/2 = 12

Answer 2

Answer: 4h 30min

Step-by-step explanation: Theoretically, if X= Number of hours required to paint the room,

X(1/6+1/18)=1

X(3/18+1/18)=1

X(4/18)=1

X(2/9)=1

2/9X=1

X=9/2h, or 4 1/2 h

One of the five cards is chosen at random. Find the probability of choosing a card with a number that

is a six. Write answer as a simplified fraction number, No decimals or percents:

Answers

Answer:

Zero.

Step-by-step explanation:

Well, assuming that the cards are numbered 1, 2, 3, 4 and 5, then the probability of getting 6 is zero, because there's no card with such number.

Remember that a simple probability is a ratio between the possible events and the total number of outcomes. In this case, the total number of outcomes is 5 and the events are zero, because there's no card with 6.

The angle is "27 and 63".

Step-by-step explanation:

Let A and B are two angles, in which  A is " [tex]\frac{1}{2}[/tex] " complementary angles  and B be is another complementary angle.

Condition of complementary angle :

[tex]A+B =90 ......(i)[/tex]

Solution:

[tex]\ A = \ 3B - 18 \\\\ \ put \ the \ value \ of \ A \ in \ equation.....(i) \\\\ \ Equation: \\ \\\Rightarrow \ A\ +\ B \ =\ 90 \\\\\Rightarrow \ 3B\ -\ 18 \ + \ B \ = \ 90 \\\\\Rightarrow \ 4B \ = \ 90 +18 \\\\\Rightarrow \ 4B = 108 \\\\ \Rightarrow B = \frac{108}{4} \\\\ \Rightarrow B \ = \ 27\\[/tex]

[tex]\ put \ the \ value \ of \ B \ in \ equation (i).\\\\ \ Equation: \\\\\Rightarrow A+B=90\\\\\Rightarrow A+27=90\\\\\Rightarrow A=90-27\\\\\Rightarrow A= 63[/tex]

What are the coordinates of the vertex of the function f(x) = x2 − 12x + 5?

(6, 31)
(−6, 31)
(6, −31)
(−6, −31)

Answers

Answer:

This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]

Step-by-step explanation:

To find the x-coordinate of the vertex of a quadratic function, we can use the formula:

[tex]x=\frac{-b}{2a}[/tex]

We are given the function [tex]f(x)=x^2-12x+5[/tex]

In this function, [tex]a=1[/tex] and [tex]b=-12[/tex]

Now we can input these values into our formula

[tex]x=\frac{-(-12)}{2(1)} \\\\x=\frac{12}{2} \\\\x=6[/tex]

This means that the x-value of the vertex is located at [tex]x=6[/tex]. To find the other half of the coordinate pair, we can now plug [tex]x=6[/tex] into the given function

[tex]f(6)=(6)^2-12(6)+5\\\\f(6)=36-72+5\\\\f(6)=41-72\\\\f(6)=-31[/tex]

This means that the coordinates of the vertex of the function are [tex](6,-31)[/tex]

Simplify the expression.
