Given V = 60 volts of an outlet in a select country, and I = 0.5 amps are being pulled to the 60 watt bulb, solve V = IR in terms of R, and

Question

substitute the given quantities. (1 point)
O R = 30 ohms
O R = 60 ohms
O R = 120 ohms
O R = 240 ohms

Answer 1

V = IR can be rearranged to solve for R:

R = V/I

Substituting the given values:
R = 60 volts / 0.5 amps

R = 120 ohms

Therefore, the correct answer is O R = 120 ohms.

Answer 2

Determine whether each equation is a valid or invalid rearrangement for the formula P = ‡(a + b) h. (2 points)
Valid
Invalid

2P = (a+b)h
2P/h =a+b
P= 1/2ah+bh
h= a+b/2P

Answer 3

2P = (a+b)h is a valid rearrangement of the formula P = ‡(a + b) h.

2P/h = a+b is a valid rearrangement of the formula P = ‡(a + b) h.

P= 1/2ah+bh is an invalid rearrangement of the formula P = ‡(a + b) h. The correct rearrangement would be P = ah + bh.

h= a+b/2P is an invalid rearrangement of the formula P = ‡(a + b) h. The correct rearrangement would be h = 2P/(a + b).

Answer 4

Genevieve and Jose are both planting square gardens. Jose's garden is 25 square feet and Genevieve's is 4 square yards. Convert their garden sizes to the same units (feet) to determine who's garden has a larger area. (1 point)

Genevieve's garden is 25 square feet, and thus, has the exact same area as vose's

Genevieve's garden is 12 square feet, and thus, has a smaller area than Jose's

Genevieve's garden is 36 square feet, and thus, has a larger area than Jose's

Genevieve's garden is 16 square feet, and thus, has a smaller area than Jose's

Answer 5

To compare the garden sizes, we need to convert Genevieve's garden size from square yards to square feet.

Since 1 yard is equal to 3 feet, and 1 square yard is equal to 3 feet * 3 feet = 9 square feet, we can convert Genevieve's garden size as follows:

Genevieve's garden size in square feet = 4 square yards * 9 square feet/square yard = 36 square feet.

Therefore, the correct answer is: Genevieve's garden is 36 square feet, and thus, has a larger area than Jose's.
