Answer:
300 ft²
Step-by-step explanation:
The area (A) of a rhombus can be calculated using
A = 
× product of diagonals, thus
A = × 24 × 25 = 300 ft²
Answer:
460 m
Step-by-step explanation:
Use right triangle PSR with right angle S to find the length of PS.
The Pythagorean theorem can be used for this.
a^2 + b^2 = c^2
(PS)^2 + (SR)^2 = (PR)^2
(PS)^2 + (150 m)^2 = (170 m)^2
(PS)^2 = 22500 m^2 = 28900 m^2
(PS)^2 = 6400 m^2
PS = 80 m
PS = 80 m; SR = 150 m
perimeter = 2(length + width)
perimeter = 2(150 m + 80 m)
perimeter = 2(230 m)
perimeter = 460 m
Answer:
you can use a calculator
Step-by-step explanation:
Answer: the total number of entries at the fair is 350
Step-by-step explanation:
Let x represent the number of entries that were there at the fair.
At a county fair, 50% of the entries are livestock. This means that the number of livestock at the fair was
50/100 × x = 0.5x
Of those entries, 80% are sold at the auction. This means that the number of entries that were sold at the auction is
80/100 × 0.5x = 0.4x
If 140 entries of livestock are sold at the auction, it means that
0.4x = 140
x = 140/0.4
x = 350
