12.4*50 gives you the hours. 12.4*50=x
Then multiply that number by 5.75.
5.75x= y
That's your answer
Answer:
48x^2-10x-72
Step-by-step explanation:
What you do is the distributive property but at one time.
So you will multiply 6x to all the numbers. Then you will multiply -8 to all the numbers.
6x(3x+5x+9)=18x^2+30x^2+54x.
-8(3x+5x+9)=-24x-40x-72.
You will then add them together to get
48x^2-10x-72 as your answer.
1/4 of the school is boys
1/2 of 1/4 is 1/8
2/3 of 3/4 is 5/12
1/4 of boys and 5/12 of girls are there
330 people are at the event
If 3/4 of the school is there, then there are 440 people in school
Let's model the problem like a circle.
The circumference of a circle is given by:
Where,
r: radius of the circle.
Clearing the radius we have:
Then, replacing values we have:
Answer:
The best approximation for the radius of the tin is:
Yes it is a 90 degree rotation clockwise.
