To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.
Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.
Your equation should look like this: 44 ÷ 50 = 0.88
This means that Marci answered 44 questions out of 50 questions correctly. (44/50)
Literally just post the questions and wait for someone to respond there’s no need to give out your number
Answer:
36°
Step-by-step explanation:
From the question,
The sum of the exterior angle of a polygon = 360
From the diagram. the polygon is Decagon
Note: A Decagon is a polygon with 10 sides.
number of sides = 10 .
The exterior angle of a regular polygon = sum of the exterior angle/number of sides.
Exterior angle = 360/10
Exterior angle = 36°
Hence the measure the single extrior angle = 36°

3x^2+2x-6-(x+5)=3x^2+2x-6-x-5=3x^2+x-11
Answer: Second option: </span><span>3x^2 + x − 11 will be a polynomial
2) </span><span>Which of the following shows that polynomials are closed under subtraction when polynomial 3x2 + 4 is subtracted from x2+ 2x + 5?
x^2+2x+5-(3x^2+4)=x^2+2x+5-3x^2-4=-2x^2+2x+1
Answer: Third option </span><span>−2x^2 + 2x + 1 will be a polynomial</span>
