Given:
Steven wrote this equation:
To find:
The error in Steven's reasoning and then find the correct product.
Solution:
We have,
This statement is incorrect because we cannot write product directly as Steven wrote.
We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.
Therefore, the correct product is 72.
Answer:
(a)80 feet
(b)$120,000
Step-by-step explanation:
<u>Part A</u>
<u>Intersecting Secant-Tangent Theorem</u>
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
In the attached diagram, the theorem applied is:
Comparing with our diagram:
|AX|=30 feet
|UX|=10 feet
Length of the Bridge,L
Therefore:
900=10(L+10)
L+10=900/10
L+10=90
L=90-10=80 feet
Length of the Bridge=80 feet
<u>Part B</u>
If each foot costs $1500
Cost of the bridge=$1500*80=$120,000
