The area of a rectangle is length times width
Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).
7/2
7 × 5 / 2 × 5
35/10
3/5
3 × 2 / 5 × 2
6/10
Answer:
Step-by-step explanation:
You must assume that N is the center of the circle.
NTP is a right triangle.
NM is the radius
NT is also a radius
The area of the circle is 25pi
25 pi = pi r^2
r^2 = 25
r = 5
The right angle triangle can be solved by
PT^2 + NT^2 = (r + 4)^2
PT^2 + 25 = (5+4)^2
PT^2 + 25 = 81
PT^2 = 56
PT = sqrt(56)
PT = 7.48
