A technique called sampling can be used to estimate population size. In this procedure, the organisms in a few small areas are counted and projected to the entire area.
let's firstly convert the mixed fraction to improper fraction.
Answer: sqrt(61)
Step-by-step explanation:
For parts a) and c1), refer to the attached picture.
For part b), the distance formula is:
d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Using x1 = -1, y1 = -4, x2 = -6, y2 = 2:
d = sqrt[(-6 + 1)^2 + (2 + 4)^2] = sqrt[25 + 36] = sqrt(61)
Part c2) Another way to find the length of AB without using the distance formula is by drawing the line and measuring it according to the scale.
Part d) This will only work as long as the graph paper is accurately made, and the scale computation is done correctly. However, this will only give approximations, and will not give an exact answer when radicals are involved.
Answer: 933.12 inches
Step-by-step explanation:
Givem that Marta has 1 cubic yard of sand to build a wall in the shape of a rectangular prisim that is 10 inches tall and 5 inches wide to the nearest foor
1 cubic yard = 46656 cubic inches
Volume = Length × width × height
Substitute all the parameters
46656 = 10 × 5 × height
46656 = 50 height
Height = 46656 / 50
Height = 933.12 inches
Answer:
21
Step-by-step explanation:
35% × 60 =
(35 ÷ 100) × 60 =
(35 × 60) ÷ 100 =
2,100 ÷ 100 =
