(3x^2- 5)(x^2+2) that is the answer
Answer: explanation
Step-by-step explanation:
1. answer:2592
explanation: it says to find the % of the small sample so 45 out of 75 is 60% then says to convert it into a decimal and multiply it by 4,320 which equals 2592.
2. answer:
explanation:540 is 12% of 4500. I don't quite understand what that number is but I'm assuming it's the percentage number and that number is 12 and that's 12% out of 100. if it means what percentage 540 is out of 100 then its 540%
3. answer:30
explanation: 4 out of 20 is 20% converted to decimal is 0.2 then multiply it by 15 0 and that adds to 30.
i hope this helped and i hope its correct
Answer:
4
Step-by-step explanation:
I73/16 = 4.52
If he wants to put the same number in each bag, he would put 4 in each bag because the pencils cannot be cut into 0.52
To find out how many 3 course meals there are you will multiply all three numbers together. The reason for this is that you can group each item with each of the other options. This is a triple grouping.
4 x 4 x 5 = 80
There are 80 possible combinations.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 40)° = 180° - 130° = 150°
--------------------------------------------------------------
sin40° = =
Multiply both sides by 21
21 × sin40° = a, thus
a ≈ 13.5 ( to the nearest tenth )
--------------------------------------------------------------
cos40° = =
Multiply both sides by 21
21 × cos40° = b, thus
b ≈ 16.1 ( to the nearest tenth )
