alexgriva [62]

Answer:

x = 30

Step-by-step explanation:

well from the theorem we have

\frac{15}{3}=\frac{x}{6}

yes i know you could say that the right way is

\frac{3}{15}=\frac{6}{x}

well if you notice they are the same only that in my way the x is in the numerator which means it will be far easier to know it's value :)

so

\frac{15}{3}=\frac{x}{6}\\\\5=\frac{x}{6}\\\\6[5]=6[\frac{x}{6}]\\\\30=x

Help me solve # 15 & 16
makkiz [27]

Answer:

15) C=frac{5}{9}(F-32)

16) 12 hours

Step-by-step explanation:

15) F=\frac{9}{5}C+32 \\F-32 = \frac{9}{5}C\\\frac{5}{9}(F-32)=C

16) If Jim drove 168 mi in 4 hours, this means it takes him

\frac{4 hours }{168 mi}

this many hours to drive 1 mile. So if we multiply this by 504 mi:

\frac{4 hours }{168 mi} 504 mi = 4 \cdot 3 hours = 12 hours

The perimeter of the given circle is 25.1 square cm.

Step-by-step explanation:

  • From the given diagram, the radius of the given circle is 4 cm.
  • The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142
  • The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm.                                                       Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.
