Answer: 8/5
Step-by-step explanation: it’s hard to explain
A=h*b/2
180 =(b-2)*b/2
360 = b^2-2b
b^2 -2b -360 =0
D = 4+1440 = 1444
b_1,2 = (2+/-sqrt1444)/2 = -18 and 20
base length equal 20 in
height equal 18 in
hope helped
Answer:
V = 67 1/2 cm^3
Step-by-step explanation:
The volume is given by
V = l*w*h
V = 4 1/2 * 6 * 2 1/2
Changing to improper fractions
V = 9/2 *6*5/2
V =270/4
V = 135/2
Changing to a mixed number
V = 67 1/2 cm^3
5,500 milligrams = 5.5 grams
