Answer: The length of DC is 3 units
<u>Step-by-step explanation:</u>
The Basic proportionality theorem states that if a line is parallel to one side of a triangle and intersects the other two at different points, then the other two sides are divided in the same ratio.
The given image is attached below.
From the BPT theorem, we can say that:
We are given:
AE = 12 units
EB = 4 units
AD = 9 units
Putting values in above equation, we get:
Hence, the length of DC is 3 units
2 3/4a=19 1/4
÷2 3/4 ÷2 3/4
a=1/7
<span>The value of 4 is 4,000 because it’s in the thousands (1,000) column. Therefore, 4 x 1,000 = 4,000. Each column has a different value. For example, 0 is in the ones (1) column, 3 is in the tens (10) column, 2 is in the hundreds (100) column, and 8 is in ten thousands (10,000) column.</span>
Answer:
A) $0.45 per oz
B) $3.51
Step-by-step explanation:
4.14/9.2 = 0.45
0.45 x 7.8 = 3.51
