D answer is 9 , 24/8 = 3
3x3=9
Answer: y= 1 2/3
Step-by-step explanation:
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²
Volume of prism = area of base * height
as both prism are similar so,
if in smaller prism Length is 5 then in Larger it is 15 that is multiple of 3
similarly , breath and height will be also multiple of 3
so, V1 = 60
then V2 = 60 *3*3*3 = 1620 cubic cm
hope it helped
