Find the unit rate for miles by dividing the time by the miles.
50 / 2.5 = 20
So it takes 20 minutes for her to walk 1 mile.
Answer:
12
Step-by-step explanation:
let x be the broken ht. then hypotenuse will be 18-x.
sin 30 = x/(18-x)
1/2 = x/(18-x)
18-x = 2x
3x = 18
x = 6
18-6 is the ht of broken part which is 12
Сorrect statements:
1. EF is the longest side
2. DF = 6 cm (in a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse. )
3. <span>By the Pythagorean theorem:
DE = </span>√(12²-6²) = √(144-36) = √108 = 6√3
DE = 6√3 cm
3 plus 2x. you add three to the amount of brother man times 2
Start by multiplying both sides by r:
Since
and
, we have that
