Answer:
8 * 7
Explanation:
When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.
The true regarding the functions on the graph is f(2) = g(2)
<h3>How to determine the true statement?</h3>
The graph that completes the question is added as an attachment
From the attached graph, we can see that both lines intersect at:
x = 2
This means that:
f(2) = g(2)
Hence, the true regarding the functions on the graph is f(2) = g(2)

Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse.
If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.
Answer:
The number is 37
Step-by-step explanation:
The given parameters are;
The unit digit of a two-digit number = 4 + The tens digit
2 × The two-digit number = 1 + The reversed number
Let x represent the unit digit and y represent the tens digit, we have;
x = 4 + y
2 × yx = xy + 1
Which gives;
2 × yy+4 = 2y2y+8
xy + 1 = 4 + yy + 1
y + 1 = 2y + 8 - 10 (we assume that the product of 2 and the unit digit is more than 10 so we subtract 10 from the product to equate the unit digits of the two numbers
10 + 1 - 8 = 2y - y
10 - 7 = y
y = 3
x = y + 4 = 3 + 4 = 7
x = 7
Therefore, the number = 37.
