It is not.
400 decimeters = 4,000 cm
4,000 cm = 40 m
15) 4m^2
17)9n^6
198a^2 (^ = power of)
Answer: b)
Step-by-step explanation:
You can rule out A) and C), because you have to find area (no adding.)
To do this problem, you can individually multiply the estimated hieght and
width by 3 and then multiply together.
This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)
9 3/4 rounds to 10
14 1/4 rounds to 14
= 3 (10) x 3 (14)
D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)
It is B)
Answer:
x= 127
w = 53
Step-by-step explanation:
X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
