The solution to the equation 15.6 + (-1.8) is 13.8.
The equation to solve is 15.6 + (-1.8).
First, add the two numbers: 15.6 + (-1.8) = 13.8.
The result is 13.8.
In this equation, you're adding a positive value (15.6) and a negative value (-1.8), which results in a smaller positive value. When you add a positive number and a negative number, you can think of it as moving to the right on the number line (positive direction) but not as far as you would if you were only considering the positive value.
So, the solution to the equation 15.6 + (-1.8) is 13.8.
To know more about equation:
Since +(-) becomes (-) we can write the given problem as
15.6-1.8
Subtraction gives us 13.8

Answer:
20/50=40% So 50 to 70 percent increase is 40%.
20/70=about 28.57% decrease for 70 to 50.
So they aren't the same because the hundred percent are different numbers in this case.

Answer:
Step-by-step explanation:
The null hypothesis is the statement or claim that is believed or assumed to be true. In this case, the null hypothesis is "They believe that 40% of first-time borrowers take out smaller loans than other borrowers". Since we are dealing with proportion, we will denote it with p. The null hypothesis would be
p = 0.4
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected. The alternative hypothesis is "They perform a hypothesis test to determine if the percentage is the same or different from 40%". It would be written as
p ≠ 0.4
What is the height of the tower (h)?
The height of the tower (h) is approximately 186.4 feet.
A ratio is simply the relation between two amounts showing how many times a value is contained within another value.
Given the data in the quesion;
We can set up a proportion to solve for the height of the tower:
Aidan's height / length of Aidan's shadow = height of the tower / length of the tower's shadow
Plugging in the values we know, we get:
5.5 / 9 = h / 305
To solve for h, we can cross-multiply and simplify:
9h = 5.5 × 305
9h = 1667.5
h = 1667.5 / 9
h = 186.4 ft
Therefore, the value of h is 186.4 feet.
