5 pieces. 4.65÷0.85=5. so u divide and ur answer is 5
L = building side
W = non-building side
P = 2W + L = 42 (note only one L because the other L is the building itself)
Solve for L:
L = 42 - 2W
Area = l*w
Area = (42-2W)W = 42W - 2W2
Let area be y, so y = -2W2 +42W
Note this is a parabola pointing down because the coefficient of the W2 is negative. That makes the vertex the maximum for which we are searching.
Vertex of this parabola is at W=-b/2a, if the quadratic is aW2 + bW + c = 0
a = -2
b = 42
W = -42/(2*-2) = -42/-4 = 10.5
W = 10.5
L = 42-2(10.5) = 42-21 = 21
Area = L*W = 21 * 10.5
A = 220.5 ft2
Answer:
ben dont know
Step-by-step explanation:
yea
There are 431 females
785-77=708
708/2=354
354=males
354+77=431
431=females
to check work do 431=354 and that equals 785
Monday: 63.8
Tuesday: 63.8 + 25.3 = 89.1
Wednesday: 89.1 + 14.5 = 103.6
63.8 + 89.1 + 103.6 = 256.5
The butcher sold 256.5 pounds of meat over the three days.
