Okay, so- The first thing I did was see how much they got done per hour. Like this:
Sally ⇒
3 hours = 1 room
1 hour = 1/3 of the room
Steve ⇒
9 hours = 1 room
1 hour = 1/9 of the room
Sally + Steve ⇒
1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9
So, they get 4/9 of a room done in 1 hour.
Number of hours needed ⇒
1 ÷ 4/9 = 2 1/4
Answer: They need 2 1/4 hours to paint the room.

Indicate whether there is exactly one solution, infinitely many solutions, or no solution to the equation shown.
2x - 4 = 2(x - 2)
Answer:
Infinitely many solution
Step-by-step explanation:
Simplify
2x - 4 = 2x - 4
Lets see:
if we put 1:
2 - 4 = 2 - 4
-2 = -2
Now lets try another number : 2
4 - 4 = 4 - 4
0 = 0
So we can say that there is more than one solution
this cancels out single solution and no solution
There are infinitely many solutions to the given algebraic expression 2x - 4 = 2(x - 2).
The algebraic expression is an expression that is composed of variables and their arithmetic operations.
From the given parameters
2x - 4 = 2(x - 2)Open brackets
2x - 4 = 2x - 4Since we are having the same algebraic expression on both sides;
Then, we won't be able to get exactly one solution but an infinite number of solutions.
This is because any number that is being substituted for the value of x will always give a different solution.

Answer:
16.7 cm
Step-by-step explanation:
Area of a triangle = ½*base*height
Area of the shaded region = area of triangle = 100.2 cm³
base = w
height = 12 cm
Plug in the value into the equation:
½*w*12 = 100.2
6w = 100.2
w = 100.2/6
w = 16.7 cm

Answer: 1196 cm³
Step-by-step explanation:
Volume of the rectangular prism: 12 x 20 x 5 = 1200 cm³
Volume of the eraser: 4 x 2 x 0.5 = 4 cm³
Therefore volume not occupied = Rectangular prism volume - eraser volume
1200 - 4 = 1196 cm³
Answer:
1196
Step-by-step explanation:
4 * 2 * 0.5 = 4
12 * 20 * 5 = 1200
1200 - 4 = 1196
evaluate the following expression log^6 8. round your answer to two decimal places
A.0.90
B.1.16
C.2.08
D.0.86
Answer:
B. 1.16
Step-by-step explanation:
Correct!
The following expression [tex]log^6 8[/tex] evaluates to 0.86. So, The correct answer is 0.86.
We can evaluate the expression log^6 8 as follows:
[tex]log^6 8 = log 8 / log 6 = 0.90309...[/tex] which rounds to 0.86 to two decimal places.
Therefore, the correct answer is D.
Logs:
The exponential function's inverse is known as the logarithm, or log. In other terms, a number's logarithm is the power that a different number, b, must be raised to in order to equal that number.
The expression log x = b represents a logarithm and is symbolized by the symbol "log". This implies that b is equivalent to x when raised to the power of log b.
For instance, since 2 raised to the power of 3 is 8, the logarithm of 8 to the base 2 is 3.
Calculus, statistics, computer science, and other branches of mathematics all make use of logarithms. Numerous more practical uses include determining pH levels and decibel levels.
