Use the left and right triangles. (the two smaller ones -- ACD and BCD)
By similar triangles ACD is similar to BCD
on the left AD/CD is one ratio
On the right CD/DB is the other. These two ratios are equal because they are corresponding parts.
AD / CD = CD / DB
AD = 3
DB = 12
CD = ??
Substitute.
3/CD = CD/12 Cross multiply
36 = CD^2
sqrt(36) = sqrt(CD^2)
CD = 6 <<<<==== Answer.
A <<<<====Answer.
Answer:
Step-by-step explanation:
1). ∵ 1 L = 1000 ml
∴ 4 L = 4000 ml
2). ∵ 1 cm = 10 mm
∴ 5 cm = 50 mm
3). ∵ 1 mg = 0.1 cg
∴ 5 mg = 0.5 cg
4). ∵ 1 ml = 0.001 L
∴ 25 ml = 0.025 L
5). ∵ 1 gm = 1000 mg
∴ 0.125 gm = 25 mg
6). ∵ 1 ml = 0.001 L
∴ 570 ml = 0.57 L
7). ∵ 1 mm = 0.1 cm
∴ 135 mm = 13.5 cm
8). ∵ 1 mg = 0.001 g
∴ 1820 mg = 1.82 g
9). ∵ 1 g = 100 cg
∴ 0.5 g = 50 cg
10). ∵ 1 ml = 0.001 L
∴ 0.2385 ml = 0.0002385 L
Answer:
Each age is 12 more than the last so the rate of change would be twelve.
Yes it is linear, every twelve pounds is 2.5 more millimeters of dosage.
