Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²
Answer:
16.373,16.4
Step-by-step explanation:
Given that a random sample of 11 university students produced the following data, where x is the minutes spent studying per day, and y is the first exam score (out of a maximum of 100 points).

Answer:
What are you trying to ask?
Step-by-step explanation:
1. The simplified form of -x + 4 is: B. - x + 4
2. B. 4 less than m
3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.
4. √3
<h3>What is the Commutative Property of Addition?</h3>
According to the Commutative Property of Addition, how numbers that are are added are ordered do not change or affect the sum of the numbers. For example, a + b = b + a.
1. To simplify -(x - 4) using the distributive property:
= -1(x) -1(-4)
= -x + 4
Therefore, the simplified form of -x + 4 is: B. - x + 4
2. m - 4 can be written as a phrase as: B. 4 less than m
3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.
4. Irrational numbers cannot be expressed, as a simple fraction. √3 cannot be expressed in simple fractions. Therefore, √3 is classified as: B. irrational.
