We want to know how many brownmies did Fred and his family eat together.
We will call to the total of the brownies by 1. On this case, after Fred ate 1/3 of the brownies, he will have:
This means that he has left 2/3 of the brownies. After his family ate 1/6 of the brownies:
This means they will have left 1/2 of the tray of brownies, and that they ate half of it.
Answer:
15 km/h
Step-by-step explanation:
To find the speed, divide the total number of kilometers by the total number of hours:
Find the total number of hours:
32 + 13
= 45
Divide this by 3:
45/3
= 15
So, the average speed was 15 km/h
Answer:
the number is 8
Step-by-step explanation:
Answer:
v=2571.13667 mm^3
Step-by-step explanation:
A marble is a sphere, and the volume of a sphere can be found using:
We need to find the radius, and we know that the radius is 1/2 of the diameter
r=d/2
r=17/2
r=8.5
Now we can substitute 8.5 in for r, and 3.14 in for pi
Answer:
x < -60
Step-by-step explanation:
Our inequality is:
-0.4x - 10 > 14
Add 10 to both sides:
-0.4x > 14 + 10
-0.4x > 24
Divide both sides by -0.4; remember that when dividing an inequality by a negative number, we must flip the inequality:
x < 24/-0.4
x < -60
Hope this helps!
