Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21
We will simplify the left hand side of the equation to look like the right
taking the LCM
expanding the binomial in the numerator
Since sin²x + cos²x = 1
factoring out the 2 from the numerator
1-sin(t) will cancel out
since cos²(t) = 1/(sec²(t))
which is equal to the right hand side of our given equation.
So we verified the identity!
Answer:
3/11
Step-by-step explanation:
3/11~ 0.2727272727272727
Here is your answer:
Find the tenth place value which is two:
74.326
Then look to the next number and see if that number is greater or equal too 5:
Now if 6 is greater than 5 you have to round up one so 2 would be 3:
74.330
Therefore the answer is "74.330."
Hope this helps!
Question 1:
think about which one Arnold has already cut the most.... he cut the green string into 6 equal size lengths. the blue he cut into 2 and the red he cut into 3 and both of those can go into 6 so six is the answer.
Question2:
same concept as question one. You're learning the basics to fractions, or division. what is the largest amount a gronola bar is cut into..... 12 pieces. But 8 doesn't divide into 12 does it so what can 12 multiply into that 8 does also..... 12x2=24 and 8x3=24 also. 4x6=24 too therefore the smallest number of equal size pieces each tray can have is 24 pieces.
Question 3:
least common denominator means the bottom number in each fraction is multiplied into the smallest number all the bottom numbers can equal. 1/2, 3/5, and 9/15... what number can 2, 5, and 15 all be multiplied into. look at the biggest number 15 it is not divisable by 2 so multiply it by 2 15x2=30. 30 is divisable by 2 and by 5 so it is the least common denominator. so double it 30x2=60.
