Given:
Circular racetrack with a diameter of 1/2 mile
Find: how far does a car travel in one lap around the track?
We need to find the circumference of the racetrack.
Circumference is multiplying pi to the diameter of the racetrack.
Circumference = 3.14 * 1/2 mile
Circumference = 3.14/2 mile
Circumference = 1.57 miles rounded to the nearest tenth is 1.60 miles.
The answer I got is -3/140 since you must multiply first, then subtract the fractions
Answer:
7/4
Step-by-step explanation:
5x/2(x/7)=14x-7
35 = 28x-14
28x=35+14
x=49/28
x=7/4
Answer:
500
Step-by-step explanation:
is 100 is 20%, multiply 100 by 5
The requested values are found in the attached table
Selected pairs
A(22,160)B(30,172)
find the slope of the line AB
m=(y2-y1)/(x2-x1)=(172-160)/(30-22)=12/8=3/2=1.5m=1.5
one point and slope-------- > A(22.160) m=1.5
y=mx+b
160=1.5(22)+bb=127y=1.5x+127---------- > equation in slope intercept form
<span>If the length of the bone is 12 in------------------ > 12*2.54=30.48 cms
</span>y=1.5x+127- >1.5*30.48+127=172.72 cms
172.72/2.54=68 in
172.72/0.30=575.73 feet
the height estimate of the person before death is 172.72 cms=68 inches=575.73 feet
<span>By the height it could be a man of average height or a tall woman</span>
