Answer: 60 gallons
Step-by-step explanation:
Given: Dimension of room = 4ft by 8ft
The height of ceiling =10 feet
The surface area of walls in a room which painter will paint= 
Since, A painter needs to cover the walls of four rooms in two coats of paint.
Then, the total area he need to paint =
If each gallon of paint covers 32 square feet.
Then, The amount of paint he needs=
Answer:
c = 7.5 meters.
Step-by-step explanation:
hello :
use phtagore - rule :
c² = 6²+4.5²
c² = 36 + 20.25
c² =56.25
c = √56.25
c = 7.5 meters.
Answer:
∠G, ∠HGI, ∠IGH
Step-by-step explanation:
» <u>Concepts</u>
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex <u>is not </u><u>I</u>.

We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0
As zero is in the denominator, it can't be defined.
In short, Your Answer would be: "False"
Hope this helps!
Answer:
Step-by-step explanation:
For equating the equations, you get
x2 + kx - 3x + 4 = 0 eq1
Setting the derivative of f(x) equal to 3 yields
f'(x) = 3
2x + k = 3 eq2
Now we substitute the value of k from eq2 into eq1.
x2 + x(3 - 2x) - 3x + 4 = 0
Solve for x from this equation. Then plug in the value of x into eq2 to solve for k
