Answer:
5/18 is a rational number because a rational number is any integer,fraction terminating decimal,or repeating decimal.
Answer:
Step-by-step explanation:
The answer is B; 90°
2×4=8 because 2 and 4 would be the addends and their less than 5 and it equal an answer between 4 and 10
Answer:
x = 12 ft, y = 24 ft
12 ft x 24 ft
Step-by-step explanation:
12 x 24 = 288 ft²
2(12) + 24 = 48 ft fencing
Answer:
A, and D
Step-by-step explanation:
A works because when you multiply like bases, you add exponents, so we have...
5^7*5^-4 = 5^(7+(-4)) = 5^(7 -4) = 5^3
B doesn't work because when you divide like bases, you subtract the exponent of the denominator from the exponent of the denominator...
5^12/5^4 = 5^(12 - 4) = 5^8
C doesn't work because there is addition.
5 + 5² = 5 + 25 = 30, and 5³ = 125
D works because 5^0 = 1, so we have
5^0(5^3) = 1(5^3) = 5^3
E doesn't work because there is subtraction...
5^3 - 5^0 = 5^3 - 1 = 124
