If the entire class lasts 7/8 of an hour, then it lasts 52.5 minutes as:
60/8 * 7 = 52.5mins or 52min 30secs
a) Then warm up and cool down lasts 3/10 of the class so this is:
52.5/10 * 3 = 15.75mins or 15min 45secs
b) Instruction is 1/5 of the class so 4/5 is not spent on instruction so:
52.5 / 5 * 4 = 42mins
Answer:
y < 5

Answer:
Step-by-step explanation:
they intersect so their equal to each other so first you wanna find x.
3x + 4 = 4x - 1
-3x -3x
4 = x - 1
+1 +1
5 = x
then plug in x on each diagonals JL and KM.
JL= 3(5) + 4 = 19
KM = 4(5) - 1 = 19
SEE? THEY ARE EQUAL WHICH MEANS MY ANSWER IS CORRECT.:)
Answer: $12a
Step-by-step explanation:
Cost of brick = $2 per foot
Cost of edging needed=?
Shape of garden = hexagonal= 6 sides and all sides are equal
The perimeter of a regular hexagon = 6×a
Where a = length of one of the sides , since the sides are equal.
Cost of edging = perimeter size (in feet) * cost per foot
Cost of edging = 6a * $2
Therefore, cost of edging = $12a
Where a = length of it's side in feet.
If you're in the 84th percentile, that means that you rank higher than the lowest 84% of the group. Out of 500 students, 84% makes 420.
