Answer:
Step-by-step explanation:
Given: △ABC, D∈AC
, m∠BDC=m∠ABC
, AD=7, DC=9.
Solution: Let BC=x, From the given figure and the given information, it can be seen that △ABC is similar to ΔBDC by AA rule, thus using the proportionality theorem, we get
⇒
⇒
⇒
⇒BC=12
Now, calculate the similarity scale,
k=
=
Therefore,

Answer:
13,000
Step-by-step explanation:
When rounding, first:
Find the place value that you are looking for, in this case, being the thousands place value. It is a 3:
1<u>3</u>,046
When you round, you will look at the place value directly next to the one you are trying to find (which is the thousands place value). In this case, it will be the hundreds place value, which has the value of 0.
When the value of the number is 5 or greater, you round up.
When the value of the number is 4 or less, you round down.
In this case, it is 0, which is less than 4, so you round down.
13,046 to the nearest thousand place value is 13,000.
