6 plates with 3 spoons or 9 plates with 2 spoons
Step-by-step explanation:
√a is defined only when a >= 0.
Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.
When 4x >= 0, x >= 0.
When x + 2 >= 0, x >= -2.
x >= 0 and x >= -2, therefore we have x >= 0. (D)
Answer:
She hung 45reds, 30greens and 60whites
Step-by-step explanation:
If Sonia is hanging up decorations in the ratio of 3red: 2green: 4white, the total amount of different she hung is 3+2+4 = 9different colours.
Of she hung 135decorations in total, the number of red = 3/9 × 135 = 45reds
Number of green = 2/9 × 135 = 30greens
Numbe of white = 4/9 × 135= 60whites
She hung 45reds, 30greens and 60whites

Answer:
54.0
Step-by-step explanation:
53.96
The bold number is in the tenth form and needs rounding off. So look at the number after the bold number (6).
Now 6 falls off the 5 or greater category, meaning that you have to add one to the bold number.
9 + 1 = 10
Now since the number is 10, you add the number before the bold number by 1 (underlined number) and replace the bold number by 0.
5<u>3</u>.96
54.00
Since you are focusing on the tenth place, keep the zero sitting on that spot.
54.0
