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.

Answer: Lower left corner [tex]\frac{29}{18+29} \times 100[/tex]
We have 29 people who chose fishing out of 18+29 people who filled out the survey. We don't use 60 because not everyone filled out the survey, and we're only focusing on survey participants. The "times 100" at the end will move the decimal point 2 spots to the right, and convert it to percent form.
For example, if you had 2 people who liked fishing out of 8 total then 2/8 = 0.25 = 25% of the people like fishing.
Answer:it's C) 29×100/18+29
Step-by-step explanation:
For the percentage, we need the total number of boys who completed the survey which is 18+29. Again, the number of boys who chose fishing is 29. So, we should divide 29 by (18+29) & multiply 100c with it in order to get the percentage .
A store is having a 20% off sale on all merchandise. If Mai buys one item and saves $13, what was the original price of her purchase? Explain or show your reasoning.
Answer:
Step-by-step explanation:
If a store is having a 20% off sale
By buying an item you save 20% of the price
If Mai saves $13 on an item she is also saving 20%
$13 = 20% of the price
$65 = 100% of the original price
$65 is your answer!
Answer:
The Answer is $65! The orignal price of the item $65 because if you save $13 on a 20% off sale it would make the orignal price $65
