Answer: 150
Step-by-step explanation:
20 is 1/3 of 60. So you can just multiply 50x3 so the answer becomes 150.
Answer:
C. 0.314.
Step-by-step explanation:
1/2 is rational. The answer is another rational number.
The only rational number in the list is 0.314.
Answer:
Explanation is below.
Step-by-step explanation:
Commutative property:
The Commutative property states that order does not matter. Multiplication and addition are commutative.
For example 2+5=5+2 .
Associative property:
The associative property states that you can add or multiply regardless of how the numbers are grouped.
For example 2x(7x5)=(2x7)x5
Distributive property:
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
For example 2(x+y)=2x+2y
Zero property of addition:
Zero is the additive identity. Adding zero to a number will not change its value. a + 0 = a.
For example 2z + 0 = 2z
Identity property of multiplication:
Property is that multiplying any number by 1 allows the number to keep its identity.
For example 14 x 1 = 14
Additive inverse:
The additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
For example 13 + -13 = 0
Answer:
1. 60°
2. r
3. 6r
4. slightly less than
5. slightly greater than 6r
Step-by-step explanation:
1. It is stated.
2 & 3. If there are 6 of the arcs and one arc is measured as r, then the perimeter is 6r.
4. The perimeter is slightly less than because the circumference is longer.
5. Use the inverse of 4.
