Answer:
b. 9h
Step-by-step explanation:
Volume of the cube = a*a*a
Volume of the cube = 3*3*h = 9h
But in reality for cube it should be 3*3*3= 27, because of the all edges of a cube are equal.
R=rate of boat in still water
c=rate of current
d=rt
since you're given that the time it takes to travel the same distance downstream and upstream, your equation will be d_1=d_2, or rt=rt
the rate upstream is r-c and the rate downstream is r+c (because the boat's and river's rates add up)
since you know t_1 and t_1 are 5 and 3, you can now set up 2 equations
<u>5*(r-c)=45</u> because (time upstream)*(rate upstream)=distance=45 miles
r-c=45/5=9
<u>3*(r+c)=45</u>
r+c=45/3=15
r-c=9 and r+c=15, so r=12 mi/h and c=3 mi/h

Answer:
3/2
Step-by-step explanation:
When given two points, we can find the slope from
m= (y2-y1)/(x2-x1)
= (13 - -2)/(8- -5)
= (13+2)/(8+5)
= 15/10
Divide the top and bottom by 5
=3/2
You can use it to find the area of a right triangle because a right triangle is basically a rectangle cut in half diagonally. However, this formula does not apply to all triangles because those that are not right triangles don't have a base or height, they're not really a rectangle. Because the formula for a rectangle's area is bxh, a right triangle is half of that. I hope this made sense and was helpful. :)
