Answer:
B
Step-by-step explanation:
1) 8
2) 6(5x+2y) factor out greatest common factor
3) 10.8 just move over decimal two places to the left.
4) 30t=150? Then t=5kg Im not sure what the last one is asking, but I’m assuming it’s to solve for t.
Answer:
The correct answer is option D: 
Step-by-step explanation:
Given:
log(y)= 3.994
Solution:
A logarithm base b of a positive number x satisfies the following definition:
For 
Also if no base b is indicated, the base of the logarithm is assumed to be 10
.
Thus, in log(y)= 3.994 base b is not indicated. so its base is assumed to be 10
now
Then
Question 9:
cos x = 10/36
Take the inverse on both sides.
arccos(cos x) = arccos(10/36)
x = 73.8723797868
x = 73.87
Question 10:
tan 89 = x
57.2899616308 = x
57.29
Answer:
Step-by-step explanation:
we have to find if the series have a constant of proportionality by dividing the value of y by each value of x
1)
100 : 2 = 50
200 : 4 = 50
300 : 6 = 50
400 : 8 = 50
ok = y
2)
0.60 : 4 = 0.15
1.20 : 8 = 0.15
1.44 : 12 = 0.12
no = n
3)
0.15 : 1 = 0.15
0.3 : 2 = 0.15
0.45 : 3 = 0.15
0.6 : 4 = 0.15
ok = y
