Step-by-step explanation:
2/3+3=3.2/3
The trick is to recognize a few things.
1. These are similar triangles, so the ratio of BU to BC is the same as BT to BA and UT to CA.
2. BC = 2 BUs and BA = 2 BTs
This means the sides of the short triangle are half the length of the sides of the big triangle.
Put in other words, CA = 2 UT
Put into an equation x+29 = 2(x+19).
x + 29 = 2x + 38
–9 = x
So that means UT = 10 and CA = 20
Answer:
200
Step-by-step explanation:
55 / 5x = 20
5x=1100
x=200
Answer:
The length of the wire in millimeters is 9 × 10² mm.
Step-by-step explanation:
1 meter is equal to 1000 millimeters. This is the ratio that we use to convert a length in meters to one in millimeters.
0.9 m × (1000 mm/ 1 m) = 900 mm = 9 × 10² mm (we round off to 1 significant figure)
