Step-by-step explanation:
You would do 5 divided by 4
the question is tells us that the sandwiches are being shared equally so it is the total amount. it is being distributed to 4 friends meaning it is being divided by 4.
5 divided by 4 = 1.25
they all got 1.25 of the sandwiches
Set h =11
11=-5t^2+25t+1
-5t^2+25t-10=0
Now use quadratic formula to solve for t
t=[-b+\-sqrt(b^2-4ac)]/(2a)
t= [-25+\-sqrt((25)^2-4(-5)(-10))]/2(-5)
t= .438sec and 4.562sec
Answer:
-1
Step-by-step explanation:
-4-(-3) ---> -4+3 = -1
Answer:
shade 6 pieces.
Step-by-step explanation:
There are 8 pieces.
It asks to shade 0.75 of it.
Make 0.75 into a fraction.
0.75 = 75/100
= 3/4
So, now multiply with 8.
8 x 3/4
= 2 x 3
= 6
So shade 6 of the pieces.
