An electrician needs 3 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/4 of a roll of wire?
Answer:
He can wire
[tex] \frac{1}{4} [/tex]
of a room with 3/4 of a roll of wire.
Step-by-step explanation:
We can solve by using proportions.
Let's set it up.
[tex] \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} [/tex]
We are now going to cross multiply. By cross-multiplting, you would get:
[tex] \frac{3}{4} = 3x[/tex]
You are now going to divide both numbers by 3 in order to get the x by itself.
[tex] \frac{ \frac{3}{4} }{3} = \frac{3x}{3} [/tex]
By dividing, you get:
[tex] \frac{1}{4} = x[/tex]
Therefore, the answer is 1/4.
The number of rooms he can wire with 3/4 of a roll of wire is 1/4.
What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.
Let the number of rooms he can wire with 3/4 of a roll of wire be x.
Now, the proportion is
[tex]\frac{3}{1}=\frac{\frac{3}{4} }{x}[/tex]
3x=3/4
x=1/4
Therefor, number of rooms he can wire is 1/4.

A line passes through the points (1, 4) and (3, –4). Which is the equation of the line?
Who ever answer this question with explanation will get Branily!!!!!
Answer:
36
Step-by-step explanation: 120/1 x 30/100 = 36
which equation represents a line that passes through points (0, 6) and (2, 0) y = -1/3x + 2 y = -1/3x + 6 y = -3x + 2 y = -3x + 6
The answer is y = 3x + 6. I corrected it to 3x becuase it wouldn't work if it was -3x. If -3x is one of the choices then mark that as the answer.
which equation represents a line that passes through points (0, 6) and (2, 0)
y = -1/3x + 2
y = -1/3x + 6
y = -3x + 2
y = 3x + 6
We have to plug in the coordinates into the equation. If x or y solved from the equation equal a coordinate in the coordinates, then it will be the correct equation.
1) 6 = -1/3x + 2
-1/3x = 4
x = 12
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
2) 6 = -1/3x + 6
-1/3x = 0
x = 0
0 = -3x + 2
-3x = -2
x = 2/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (2,0).
3) 6 = -3x + 2
-3x = 4
x = -4/3
This equation doesn't work. Even if the other pair works, it still doesn't satisfy (0,6).
4) 6 = 3x + 6
3x = 0
x = 0
0 = 3x + 6
3x = 6
x = 2
This equation works.

For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total cost of the meal is $32 and is represented by the equation 2x + 18 = 32. How much does each sandwich cost?
A) $14
B) $22
C) $7
D) $28
Answer:
C
Step-by-step explanation:
thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.
First, subtract 18 from both sides to eliminate it.
2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14
Next, separate the 2 from the x by dividing it from both sides:
2x = 14 ----> 2x/2 = 14/2 ----> x = 7
By solving this equation, we find that x, or one sandwich, costs $7.

b) Write an equation to model the position of the diver at any given time.
c) After how long will the diver be able to catch the turtle?
d) At what depth will the diver be able to catch the turtle?

Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.
