We are given
For Monday:
Morning temperature =68 F
but, by the afternoon, the temperature had risen 18 oF
so, afternoon temperature =68+18=86F
For Tuesday:
the temperature had dropped 21 oF since Monday afternoon
so, morning temperature=86-21=65F
but rose 20 F by the noon
so, noon temperature =65+20=85F
now, we can find temperature difference
temperature difference = 85F-68F
temperature difference = 17F.......................Answer

Step-by-step explanation:
Number of 4th grade students who become cheerleader = 22
Number of 5th grade students who become cheerleader = 26
Number of cheerleaders in each cheer leading groups = 8
We need to divide the total number of cheer leaders into groups of 8.
Let represent the number of groups that can be formed.
Total number of students who want to become cheerleaders =
So, equation to find the number of groups can be given as :
⇒
⇒
Thus,a total of 6 cheer leading groups can be formed.
Answer:
Step-by-step explanation:
area including track=area of 2 semi circles+area of rectangle
=2×1/2×π×46²+86×65
=2116 π+5590
area of grass=2×1/2×π×40²+80×65=1600π+5200
≈10226.55 m²
area of track=2116π+5590-1600π-5200
=516π+390
≈2011.06 m²
