Answer:
5√2
Step-by-step explanation:
√8 + √18
We first have to find what is the largest perfect square that goes into √8:
4 is the largest, so therefore → √8 gives you 2√2:
Work: √4 * √2 → 2 * √2 → 2√2
Now we have to find what is the largest perfect square that goes into √18:
9 is the largest, so therefore → √18 gives you 3√2:
Work: √9 * √2 → 3 * √2 → 3√2
Because 2√2 and 3√2 have the same "base" of √2, they can be added together:
2√2 + 3√2 = 5√2 (The "bases" are to be left alone!)
Answer:
x = 44
Step-by-step explanation:
3x - 5 is complementary to y° so their sum is 180°
The angle with measure 127° is also complementary with y°
127 + y = 180
y = 53°
53 + 3x - 5 = 180
3x + 48 = 180
3x = 132
x = 44
Mean = (1+1+2+3+3+3+4+5)/8 = 22/8 = 2.75
answer
mean = 2.75
5.) Answer: 0.45
Step-by-step explanation:
There is 1.5 quarts of paint, and 30% is yellow.
30% of 1.5 is 0.45.
6.) Answer: 7.198
Step-by-step explanation:
$499.99 is 100%. We need to find $35.99 off of it in percentage.
499.99/35.99 = 100/x
499.99x = 3599, x = 3599/499.99
x ≈ 7.198
The answer is 54.609 is less than 54.69
