Answer:
the answer is C
Step-by-step explanation:
Answer:
5/(3x+2) = 7/(5x-2)
<=>5*(5x-2) = 7*(3x+2) (x is not equal to -3/2 or 2/5)
<=> 25x -10 = 21x +14 (x is not equal to -3/2 or 2/5)
<=> 4x = 24 (x is not equal to -3/2 or 2/5)
<=> x = 6 (valid)
Answer: radius = 47.8 inches
Step-by-step explanation:
An arc is a portion of the circumference of the circle. The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
θ = 60 degrees
Length of arc = 50 inches
Therefore,
50 = 60/360 × 2 × 3.14 × r
Cross multiplying by 360, it becomes
18000 = 376.8r
r = 18000/376.8
r = 47.8 inches
Answer:
a) 100/15 = 6.6667 = 6 2/3
b) C = T( 6 2/3)
= T (6 + 2/3)
C = 1T x 6 2/3
= 6 2/3 T
We can show T as time at end of equation or start of brackets
Answer:
Step-by-step explanation:
<u><em>The triangles can not be proven congruent.</em></u>
We have AAA theorem ⇒ given triangles are similar for sure.
