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 debt of $3571.31 is due November 1, 2025. What is the value of obligation on May 1, 2016, if money is worth 4% compounded semi-annually?
The is the value of the obligation is $____.
Answer:
2500.49
Step-by-step explanation:
--Given--
Amount (A): $3571.31
Rate (r): 4%
Compound (n): 2 **semi-annually means 2 times a year**
Time (t): 9 **2016 to 2025 is 9 years time**
--Solve--
P = A / (1 + r/n)^nt
= 3571.31 / (1 + .04/2)^(2 * 9)
= 3571.31 / (1.02 )^(18)
= 3571.31 / 1.02¹⁸
= 3571.31 / 1.02¹⁸
= 3571.31 / 1.428246
= 2500.49

Given ∆ABC≅∆DEF, m∠A=5x+12 and m∠D=8x, find m∠A and m∠D.
Given :
Two triangle ∆ABC and ∆DEF are congruent.
m∠A=5x+12 and m∠D=8x.
To Find :
m∠A and m∠D.
Solution :
Since, both the triangle are congruent.
m∠A = m∠D
5x + 12 = 8x
3x = 12
x = 4
m∠A = 5(4) + 12 = 32°
m∠D = 8(4) = 32°
Therefore, value of m∠A and m∠D is 32°.

Mora is using a map to find the distance between her house and her cousin's house. She knows that $2$ centimeters on the map represent $300$ miles. On the map, the distance between her house and her cousin's house is $20$ centimeters. What is the distance, in miles, between Mora's house and her cousin's house?
Answer:
3,000 miles
Step-by-step explanation:
Calculation for the distance, in miles, between Mora's house and her cousin's house
Distance in miles =(2centimeters÷20centimeters) *300 miles
Distance in miles=10*300 miles
Distance in miles= 3,000 miles
Therefore the distance, in miles, between Mora's house and her cousin's house will be 3,000 miles
