The unit cost is $0.55. $0.55 x 12 (a dozen) = $6.60
The answer I got is 155.5. First I broke this into a rectangle ad a trapezoid. The rectangles area is 15x5 = 75. The area of the trapezoid is 1/2(8+15)7 = 23x3.5 = 80.5. So 80.5 + 75 = 155.5
The interest is 30 dollars I believe.
Answer:
Step-by-step explanation:
Given: i. AB||DE
ii. AC≅DC
Prove: ΔABC≅ΔDEC
From the two triangles, it can be observed that;
m<BAC≅m<EDC (alternate angles)
m<ABC≅m<DEC (alternate angles)
m<BCA≅m<ECD (vertically opposite angles)
m<BAC + m<ABC + m<BCA = m<EDC + m<DEC + m<ECD = (sum of angles in a triangle)
Since the three angles of the triangles are congruent respectively, then;
ΔABC≅ΔDEC (AAA congruence property)
Midpoint is (3.5,2.5)
distance is square root of 18
