Answer:
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)
Answer:
D) 32.5 ft
Step-by-step explanation:
Here we have to use the trigonometric ratio.
We need to find the length of the hypotenuse.
We use sin ratio.
Sin 38 = Opposite / Hypotenuse
Here opposite = 20, Hypotenuse = Length of the six cars
sin 38 = 20 / length of the six cars
The length of six cars = 20 / sin 38
The length of the six cars = 32.48
Which is closest to 32.5 ft
Thank you.
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
So yuo simplyfly
15:20=3:4
6:8=3:4
8:12=2:3
9:12=3:4
so your answer is not c
