Answer:
60%
Step-by-step explanation:
12 kids played. 8 didn't play. That means there is a total of 20 students.
The fraction would be 12/20.
To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)
100 divided by 20 is 5
12 x 5 = 60
Answer:
60%
Step-by-step explanation:
theres 20 kids and 12 played so yeah its pretty simple
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 lost turtle - swimming 13 feet below the surface of the water - begins to ascend at 0.5 foot per second. In hopes of (harmlessly) capturing the turtle, a diver jumps into the water to a depth of 4 feet before descending at a rate of 0.25 foot per second.
a) Write an equation to model the position of the turtle at any given time.
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?

Answer:
Step-by-step explanation:
Iii
Answer: i dont even know?
Step-by-step explanation:
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.

2 Large Box=6.24
3 Small box=5.04Answer:
0.14
0.13
0.01
0.48 or -1.2
Step-by-step explanation:
Easye as pie
16 ounce is 2.24
24 ounce is 3.12
ok 2.24/16
0.14 price per ounce
for first one
now second one
3.12/24
0.13price per ounce
second one
0.14-0.13=0.01
for last question
2 large boxes=6.24 dollars
each large box=24ounces
2 boxes=48
0.13*48=6.24
6.24 dollars for 2 large boxes
3 small boxes=5.04
0.14 each ounce and 12 each small box
so 12*3=36
36*0.14
5.04
so if the smalle box had 48 ounces it would costs 6.72
2 Large Box=6.24
3 Small box=5.04
-1.2
now into the ounces
6.72-6.24
0.48

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.
