Two sides of a right triangle are 8” and 12”.A. Find the the area of the triangle if 8 and 12 are legs.
B. Find the area of the triangle if 8 and 12 are a leg and hypotenuse.
Answers
where a and b are both legs of the triangle.
A) a = 8 inches ; b = 12 inches
A = (8in x 12in)/2 = 96/2 = 48 in²
B.) a = 8 inches ; b = ? ; hypotenuse = 12 inches
Pythagorean theorem is used to get the measurement of the hypotenuse. It can also be used to get the measurement of the missing leg.
a² + b² = c² ⇒ b² = c² - a²
b² = 12² - 8²
b² = 144 - 64
b² = 80
b = √80
b = 8.94
A = ab/2 ⇒ (8 inches * 8.94 inches)/2
A = 71.52 in² / 2
A = 35.76 in²

If A is on the one side of the equation, and bh/2 is on the other side, it means that our goal is to get to the point when b is alone on one side of the equation, doesn't matter which.
When working with equations like this, always remember that if X is the number that you divide by on one side, when you transfer it to the other side of the 'equal' sign it is going to switch is function and become a multiplier. So, in this case, when we transfer the number two on the other side it is going to become 2xA and we will have left 2 x a=b x h.
To get b alone, as we wanted to, we will transfer h on the other side and it will become the divider, adn we will get the solution: 2A/h=b
Hope this helps :)

Do you know how to simplify, let's say for example, x⁵/x² ?
When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator. So x⁵/x² = x³ .
Now look at x⁷/x⁷ . From that same handy tip, x⁷/x⁷ = x⁰ .
BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '. So x⁰ = 1 , no matter what 'x' happens to be.
Does that do anything for you ?

Answer:
$35.10
Step-by-step explanation:
Original price = $45.00
Markdown = 22%
Therefore, 22% × 45.00
= × 45.00
= 0.22 × 45.00
= $9.9
Now subtract $9.90 from $45.00
= $45.00 - $9.90 = $35.10
$35.10 is the answer.
0.22×45= $9.90 markdown so 45-9.90= $35.10 is the sales price

Answers
The confounding variable, often described as a confounder or confusing factor, is a dimension in studies looking at a possible causation link, and further calculation can be defined as follows:
- It has connected both to the study's apparent cause and its ostensible impact.
- It can be difficult to differentiate between both the genuine relationship between the independent variable and the effect of a contextual factor.
- It is an external factor that alters the impact of variables to utilized to sway the findings of an experiment.
Therefore, the final answer is "Confounding variable".
