Answer:
288J
Step-by-step explanation:
recall the formula for kinetic energy
KE = (1/2) mv²
where m is the mass (= 4kg) and v is the velocity(=12 m/s)
hence
KE = (1/2) (4)(12)² = 288J

132.4
Step-by-step explanation:
Solution
Step 1
The opposite angles of a parallelogram are equal:
Step 2

The equation is made true by the opposite angles theorem is
85 + y = 3y - 15
or
y = 50
Answer:
3/8 of the pizza
Step-by-step explanation:
3/4*reciprocal of 2
3/4*1/2
3/8
Subtract 2b by both sides which gets -b+4=-5 then subtract 4 by both sides so you get -b=-9 and divide -1 by both sides so that b=9
