The voltage in a circuit is the product of two factors, the resistance and the current. If the voltage is 6ir + 15i + 8r+20, fin

zhuklara [117]

Answer:

resistance: (2r +5)
current: (3i +4)

Step-by-step explanation:

The factors of the given expression are ...

6ir +15i +8r +20 = (3i +4)(2r +5)

Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...

resistance: (2r +5)

current: (3i +4)

A flower garden is shaped like a circle. Its diameter is 40yd. A ring-shaped path goes around the garden. The width of the path

stellarik [79]

Answer:

Number of sand bags needed = 124

Step-by-step explanation:

Diameter of garden = 40 yd

Width of path = 6 yd

Diameter of garden with path = 40 + 2 x 6 = 52 yd

We need to find area of path.

Area of path = Area of garden with path - area of garden

$\texttt{Area of path = }\frac{\pi \times 52^2}{4}-\frac{\pi \times 40^2}{4}\\\\\texttt{Area of path = }867.08yd^2$

Area covered by one sand bag = 7 yd²

$\texttt{Number of sand bags required = }\frac{\texttt{Area of path}}{\texttt{Area covered by one sand bag}}\\\\\texttt{Number of sand bags required = }\frac{867.08}{7}=123.86\approx 124$

Number of sand bags needed = 124
