12. if ajkl is an equilateral triangle, jk = 13x + 5, kl = 17x - 19, and jl = 8x + 35, find
x and the measure of each side.
answer: p=19.2 ft
by the triangle midsegment theorem, you have:
then, the lengths of the sides of the triangle are:
add them to obtain the perimeter, then you obtain the following result:
p=8 ft+6.4 ft+ 4.8 ft
to start, let's find the distance between a and b when they both start moving. this is two hours after the car starts moving, and that is 2*60=120 miles. there are 620 miles total, so they are 500 miles apart when they both start moving. notice that they are moving in opoposite directions, so every hour they will get 60+40=100 miles closer to each other, so it will take 500/100=5 hours to meet. to find the distance from city a, we need to find how far the car moved, which is just 2+5=7 hours times 60 mph or 420 miles away from city a.
c. the volume of the sun is approximately one thousand times the volume of jupiter.
the volume of the sun is approximately 1 × 10^18 cu km, while the volume of jupiter is approximately 1 × 10^15 cu km.
we can take the ratios of the volumes of sun to jupiter.
volume of sun / volume of jupiter = (1 × 10^18 cu km) / (1 × 10^15 cu km)
volume of sun / volume of jupiter = 1000.
volume of sun = 1000 x volume of jupiter.
