Answer:
Sources of electrical current
Step-by-step explanation:
Based on the information given the reason why
He/ She places a compass at different positions on a wall until the compass needle change to a direction was because the construction worker
was most likely using the compass to find the Sources of an ELECTRICAL CURRENT or where the ELECTRICAL CURRENT originated from reason been that ELECTRICAL CURRENT is the movement of electric charge from cathode to anode .
Answer:
The correct option is;
A total of forty hours a week
Step-by-step explanation:
The given information in the question are;
The number of hours of sleep Nina gets during weeknights = five hours
The number of hours of sleep Nina gets per night on weekends = ten hours
The number of days in a week = 5 days
The number of days in a weekend = 2 days
Therefore;
The number of hours of sleep Nina gets per week = 5 days × 5 hours/day + 2 days × 10 hours/day
∴ The number of hours of sleep Nina gets per week = 25 hours + 20 hours = 45 hours
The number of hours of sleep Nina gets per week = 45 hours
To better concentrate on schoolwork, Nina could get a total of forty hours a week of sleep a week to increase the number of hours she spends weekly on her schoolwork by up to 5 hours (45 hours - 40 hours).
Answer: common difference = -5
Step-by-step explanation:
This is an arithmetic progression. The common difference will be gotten by subtracting the 1st term from the 2nd term. This will be:
1st term = 12
2nd term = 7
3rd term = 2
Common difference = 7 - 12 or 2 - 7 = -5
It isn't an geometric progression as the ratio isn't thesame
= 2nd term / 1st term
= 7/12
= 3rd term / 2nd term
= 2/7
Therefore, it's an arithmetic progression with difference of -5
Answer:
The value of x will be:
Step-by-step explanation:
Given the equation
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
simplifying the equation by subtracting 14 from the L.H.S
Subtracting 15 from both sides
combining the like terms
dividing both sides of the equation by 5
Therefore, the value of x will be:
The perimeter of the polygon, which is a trapezoid with the given parameters, is: A. 25 cm.
<h3>What is the Perimeter of a Polygon?</h3>
To find the perimeter of a polygon, sum all the length of the sides of the polygon.
Given the sides of the trapezoid as 8 cm, 5 cm, and two sides of 6 cm each
Perimeter = 8 + 5 + 6 + 6
Perimeter = 25 cm.
