Complimentary angles will add up to 90 degrees
x + y = 90
x = 2y
2y + y = 90
3y = 90
y = 90/3
y = 30......this is one angle
x = 2y
x = 2(30)
x = 60.....this is ur other angle
and ur larger angle is 60 degrees
Answer:
x = -8
y = 9
Step-by-step explanation:
to solve this expression using simultaneous equation, we would say let
y =9............................................. equation 1
6x + 5y =-3............................................equation 2
substitute equation 1 into equation 2
-3 = 6x + 5y............................................equation 2
6x + 5(9) = -3
6x + 45 = -3
collect the like terms
6x = -3-45
6x = -48
divide both sides by the coefficient of x which is 6
6x/6 = -48/6
x = -8
therefore y = 9
x = -8
Answer:
4
Step-by-step explanation:
p(3) = 2³ = 8
p(2) = 2² = 4
8-4 = 4
The value of log(0.47) after rounding to 4 decimal place is -0.3279
Option D
Given :
Find the value of log(0.47) using calculator
To find the log value we use the calculator
here we are asked to find out log (0.47) that is the log (decimal)
we cannot find the log value without calculator because we have decimal argument inside log.
Use scientific calculator
Press log first then enter the number 0.47 inside a parenthesis
Press enter , it will show you the log(0.47)
log(0.47) =-0.327902142
Now round the answer to 4 decimal places
We have 0 in the 5th decimal place . so we keep 9 as it is
log(0.47) =-0.3279

Answer:
A. Positive
Step-by-step explanation:
They ask us about the relationship between reading and grades.
First you have to go to the first part of the statement that says:
"Dr. Yancy conducted a correlation study in which she found that the more time children in her study read at home the better they performed in school"
In this case they tell us that there is a positive correlation, that the more you read the better your performance in school is.
Performance is your grades, and home study can be reading, so the score is positive in the second half, too.
