2 answers:
Answer:
Both are correct.
A) A decimal fraction
B) A common fraction
Step-by-step explanation:
<u>1 step.</u> Write down 0.4 divided by 1:
<u>2 step.</u> Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):
This fraction is called a decimal fraction.
<u>3 step.</u> Simplify the decimal fraction:
This fraction is called a common fraction.

Answer:
9.93
Step-by-step explanation:
Secant-Tangent theorem tells us that the product of the secant segment with its external segment is equal to the square of the tangent segment.
From the diagram, we can say (let the unknown part of secant line, the part left of the segment length 5, be y):
(15+y)(10) = 17^2
Solving for y we get:
Now we can use the chord theorem to solve for x. Chord theorem tells us that when 2 intersecting chords create 4 segments, the product of the individual chord segments are equal. Thus we can say:
5 * 13.9 = 7 * x
Now solving, we get:
Thus x = 9.93
last answer choice is right.
