The shape shown here is a triangular pyramid, because it has a triangular base and a pointy tip.
He would have four fields. Since the area of 1/2 milex1/2 mile is 1/4, and 1x1 is 1, so 4 fields make up the land.
The volume of the sphere is expressed in the formula V= 4/3 3.14r^3 and we are given the radius of the sphere. to find the volume, we can directly substitute r as the unit of the volume to be determined is consistent with the given. Hence, via subsitution, the answer is 1.7671 cubic feet
Answer:
x = 25.6
Step-by-step explanation:
As we can see, this is a right triangle, so there are known relationships
well to start we have to know the relationship between angles, legs and the hypotenuse
α = 43
a: adjacent = x
o: opposite
h: hypotenuse = 35
sin α = o/h
cos α = a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
cos α = a/h
cos 43° = x / 35
cos 43° * 35 = x
25.59 = x
if we want to round to the nearest tenth
x = 25.59 = 25.6
The ratio birds : animals = 13 : 2
so for every 1 animal, 6.5 birds were born
last month: animals = birds - 44
birds - animals = 44
use trial and improvement to find:
if there were 52 birds, there must be 8 animals
CHECK: 52 - 8 = 44
