Answer:
48 cm
Step-by-step explanation:
Given:
Distance of rod from the wall = 45 cm
Distance of rod from the light = 15 cm
Length of rod = 12 cm
We can see that <DAM and <BAF are equal
Also, <DMA and <BFM are equal because they are corresponding angles
To find the length of the shadow, let's take the equation
Where.:
DM = ½ of length of the rod = ½*12 = 6
A.F = 15 + 45 = 60 cm
AM = 15 cm
Therefore,
Cross multiplying, we have:
15 * B.F = 60 * 6
15 * B.F = 360
BF = 24 cm
The shadow on the wall =
2 * BF
= 2 * 24
= 48 cm
The shadow on the wall is 48 cm
1 yard = 36 inches
2 yards = 72 inches
Solution: 2 yards is more
Answer:1-3. 2-1. 3-4. 4-3
Step-by-step explanation:
Answer:
t < 2
Step-by-step explanation:
- 15t – 6 < 12t
- 15t - 12t < 6
- 3t < 6
- t < 6/3
- t < 2
a parallel line to that one above, will have the same exact slope, since parallel lines have the same slope.
