Jamal works as an electrician's apprentice. He rewired 4 electrical outlets in 1 and one-halfhours. If he works at the same pace for 7.5 hours, how many outlets will he rewire? 5 outlets 13 outlets 20 outlets 30 outlets
Given :
Jamal works as an electrician's apprentice. He rewired 4 electrical outlets in 1 and one-halfhours.
To Find :
If he works at the same pace for 7.5 hours, how many outlets will he rewire.
Solution :
Let, rate of wire rewired in one hour is r.
So, [tex]r=\dfrac{4}{1.5}\ = \dfrac{8}{3}\ rewire/hour[/tex].
Now, number of outlets rewired in 7.5 hours are :
[tex]N=7.5\times\dfrac{8}{3}\\\\N = 20[/tex]
Therefore, he will rewire 20 outlets in 7.5 hours.
Hence, this is the required solution.
Answer:
20 outlets
Step-by-step explanation:
Number of outlets rewired in 1.5 hours = 4
Jamal keeps on working at the same pace 7.5 hours.
To find:
Number of outlets rewired = ?
Solution:
The answer can be found by using the unitary method.
First of all, we need to find number of outlets rewired in 1 hour.
And then, we can multiply with 7.5 to find out the answer.
Number of outlets rewired in 1.5 hours = 4
Number of outlets rewired in 1 hour = [tex]\dfrac{4}{1.5} = \dfrac{40}{15} = \dfrac{8}{3}[/tex]
Number of outlets rewired in 7.5 hours = [tex]\dfrac{8}{3}\times 7.5 = \bold{20}[/tex]
So, 20 outlets can be rewired in 7.5 hours.

A bag contains 26 tiles, each with a different letter of the alphabet written on it. You
choose 3 tiles from the bag without looking. What is the probability that you choose
the tiles with the letters A, B, and C?
Answer:
1/26
Step-by-step explanation:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Answer:
a) 7 days
b) 52 pictures
Step-by-step explanation:
a) If p=pictures and she took 37 pictures, then plug in 37 into p, in the equation the solve.
If you have trouble solving the first step is to subtract 2 from both sides (both sides to cancel out the original 2, and so that 5d can be by itself).
37 = 5d + 2
-2 -2
35 = 5d
The final step is to divide 5 on each side to get d (the number of days by itself). Then you get the answer, d=7, which means that the number of days Lola spent on vacation if she took 37 pictures, would be 7 days.
35 = 5d
5 5
7=d or d=7
b) If d=days and she spent 10 days on vacation, then plug in 10 into d, in the equation then solve.
If you have trouble solving the first step is to multiply 5 by 10. Which will make you end up with 50 + 2
p = 5(10) + 2
p = 50 + 2
Then the final step is the add 50 and 2 together. This will get you the answer p=52, which means that the number of pictures Lola took for the 10 days she was on vacation would be 52 pictures.

Roberto bought a $330,000 house, paying 18% down, and financing the rest at 4.6% interest for 30 years. Her monthly payments are $1387.22. How much will he really pay for her $330,000 house?
Answer:
$558,799.2
Step-by-step explanation:
Given that:
Cost of house = $330 000
Down payment = 18% of cost
Down payment amount = 0.18 * 330,000 = $59,400
Monthly payment = $1387.22
Period of payment = 30 years
Monthly payment after 30 years:
$1387.22 * (30 * 12) = $499,399.2
Hence, amount actually paid :
$59,400 + $499,399.2
= $558,799.2

Which equation is equivalent to Y — 3 = 4 (X—5)
Answer:
Last one :)
Step-by-step explanation:
The required equation y = 4x - 17 is equivalent to the given equation - 3 = 4 (x - 5). which is the correct answer that would be an option (B).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question below as:
y - 3 = 4 (x - 5)
We have to determine the equivalent equation to the given equation.
Now, As per the given equation :
⇒ y - 3 = 4 (x - 5)
Apply the distributive property of multiplication,
⇒ y - 3 = 4x - 20
Rearrange the terms of variables in the above equation,
⇒ y = 4x - 20 + 3
Apply the subtraction operation,
⇒ y = 4x - 17
Therefore, the required equation y = 4x - 17 is equivalent to the given equation.

What date and time is it 2011 minutes after the beginning of January 1 2020
Answer:
Okay!
Notable things in the problem:
2011 minutes AFTER the beginning of January 1rst.
12:00AM will be our starting time, because that's when January 1rst begins.
It'll be a bit easier to work with if we convert the 2011 minutes into hours.
So take 2011 minutes and divide it by 60 to get the number of hours.
2011 / 60 = 33 hours and 31 minutes
You wouldn't be able to easily get the exact number of minutes from a calculator. You'll need to use long division. The remainder will be the number of minutes. If you want to check you can multiply the number of hours by 60 and add 31 to the product. If it doesn't equal 2011 minutes then something is amiss.
12:00 AM
Since we know this is a 24 hour clock we can subtract 24 from our number of hours. (Just remember that this is the next day)
12:00 AM with 9 hours and 31 minutes left.
9:31 AM a day later is our time!

The two expressions represent the number of people entering a theme park on Saturday and Sunday. Saturday. 508 x minus 70. Sunday. 405 x minus 26. Which expression could represent the total amount of people entering the theme park that weekend?
Answer:
913x - 96Step-by-step explanation:
Given
The expression of number of people entering on Saturdays = 508x-70
The expression of number of people entering on Sundays = 405x-26
total amount of people entering the theme park that weekend = Total entering on Saturday + total entering on Sunday
Substitute the expression;
total amount = 508x - 70 +(405x-26)
total amount = 508x+405x-70-26
total amount = 913x - 96
Hence the total amount of people entering the theme park that weekend is 913x - 96
