Answer:
90
Step-by-step explanation:
A semicircle is 1/2 of a circle
A circle is 360 degrees
1/2 is 180
We have 90 degrees already used on the left
180-90 = 90
b = 90 degrees
Answer:
10
Step-by-step explanation:
first u take 2 1/2 and change it into a improper fraction.
so 2 X 2 = 4 then + 1
=5
5/2 divide by 1/4
which is 10
Answer:
...............
Step-by-step explanation:
We are given with the inequality |2x + 1| ≤ 5 and asked to solve the equation. In this case, we take first the positive side, that is 2x + 1 ≤ 5. this is equal to 2x ≤ 4 or x ≤ 2. For the negative side, the equality is -5 ≤ 2x + 1. This is equal to -6 ≤ 2x or -3 ≤ x. Hence the solution is -3 ≤ x ≤ 2. The answer is B. closed dots on -3 and 2 with shading in between. The equal in <span>≤ means closed dots.</span>
Answer:
Commutative Property
Step-by-step explanation:
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
