Answer: 30 kilograms
explanation: Each 1000 grams converts to 1 kilogram
The first one is 21.93 rounded up to 22.
C = 2πr
C = 2π5
C = 2 (3.14) (5)
C = 2 (15.7)
C= 31.4
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
150. Divide 5000 by 100 and you get 50. Multiply 3 by 50 and you get 150.
