The numbers are -10, -9, and -8.
Given expression: − 11.50 (1.32 + 0.48).
We need to simplify it and get the answer in decimals.
Note: In order to simplify above given expression, we need to apply order to operations.
According to order to operations, we need to simplify parenthesis first.
So, we need to add 1.32 + 0.48 first.
1.32 + 0.48 = 1.80.
So, − 11.50 (1.32 + 0.48) would become -11.50(1.80).
Now, we need to multiply -11.50 by 1.80.
-11.50(1.80) = -20.7.
<h3>Therefore, final answer is -20.7.</h3>
Answer:
no
Step-by-step explanation:
To figure out the percentage you got correct, we need to set up fractional proportions.
We already have one fraction, 14/20.
Since we are looking for a percentage, we need to have a maximum total percentage that represents the total score.
100% is the maximum percentage for any total.
So we have our fractional proportions set;
14/20 : x/100
To solve for this, we need to cross multiply the numerator (top number) of one fraction by the denominator (bottom number) of the other fraction.
Let's try this!
14 • 100 = 1400
20 • x = 20x
Now that we have our products, set them as an equation.
20x = 1400.
To solve for x, we need to divide both sides by 20.
20x / 20 = x
1400 / 20 = 70.
You are left with:
x = 70.
Your answer is:
If you get 14/20 on a test, you would get 70% of the questions correct.
I hope this helps!
