Answer:
Since congruent means that they have the same diameter , i'd say that the answer is 1
Step-by-step explanation:
Answer: 79 seconds.
Step-by-step explanation:1) we have to calculate the lenght of the baseball field.
perimeter of the baseball field=2(radius)+lenght of a semicircle.
2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)
Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,
2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.
10 ft------------------------1 second
789,82 ft----------------- x
x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s
Answer:
7x - 6y = 16
y = (-5)
using substitution method
7x - 6(-5) = 16
7x +30 = 16
7x = 16 - 30
7x = 14
x = 14/7
x= 2
Answer:
8 feet by 3 feet by 7 feet
7 feet by 6 feet by 4 feet
Step-by-step explanation:
8 × 3 × 7 = 168
7 × 6 × 4 = 168
Complementary angles add up to 90
Supplementary angles add up to 180
