Two gears are adjusted so that the smaller gear drives the larger one. The radius of the smaller gear is 3.7 cm and the radius o
SIZIF [17.4K]

Answer:

\theta=156^0

Step-by-step explanation:

The smaller gear rotates through an angle of 300°.

In radian, 300°= 300X\frac{\pi}{180} =\frac{5\pi}{3}

The arc length, s on the smaller gear(with a radius of 3.7 cm) is:

s=r\theta

s= \frac{5\pi}{3} X 3.7=\frac{18.5\pi}{3}

The larger gear moves through the same arc length.

Therefore:

Arc length of the larger gear, s=\frac{18.5\pi}{3}

Radius of the larger gear =7.1cm

s=r\theta

\frac{18.5\pi}{3}=7.1\theta\\\theta=\frac{18.5\pi}{3X7.1}\\\theta=\frac{18.5\pi}{21.3}

To convert back to degrees

\theta=\frac{18.5\pi}{21.3}\\\theta=\frac{18.5\pi}{21.3}X\frac{180}{\pi} =156.33\\\\\theta=156^0

The larger gear rotates through an angle of 156 degrees.

kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza. Define a variable and write an expression to represent th
Stels [109]

The total cost, if one drink costs $3 is $27.75

  • Let the cost of a pizza be x

  • Let the cost of a drink be y

If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y

Since a pizza costs $12.75, hence x = $12.75

The function becomes 12.75 + 5y

f(y) = 12.75 + 5y

To get the total cost if one drink costs $3, hence;

f(3) = 12.75 + 5(3)

f(3) = 12.75 + 15

f(3) = 27.75

Hene the total cost, if one drink costs $3 is $27.75
