Which of the following is the best estimate of the number of centimeters in 1 yard? (Note: 1 yard = 3 feet; 1 foot= 12 inches; 1 inch= 2.54 centimeters)
A. 36
B. 72
C. 90
D. 180
1 yd = 3 * 12 = 36 ft
36 * 2.54 = 91.44
1 yd = 91.44 cm
(1/2)(10t) =50,000 Solve the equation above for t. Which of the following is correct?
A. 250
B. 1,000
C. 2,500
D. 10,000 .
Dear Roberta,
the answer is D
(1/2)(10t) =50,000
(10t) =50,000 /(1/2)
10t= 100000
t = 10000
Hope it helps!
Wishing you the best of luck

To find the number of centimeters in 1 yard, we need to convert each unit of measurement step by step.
1 yard = 3 feet (since 1 yard equals 3 feet)
1 foot = 12 inches (since 1 foot equals 12 inches)
1 inch = 2.54 centimeters (since 1 inch equals 2.54 centimeters)
To find the number of centimeters in 1 yard, we can multiply the conversion factors together:
1 yard = 3 feet * 12 inches * 2.54 centimeters
Calculating this expression will give us the number of centimeters in 1 yard.
Now let's calculate each option to see which is the best estimate:
A. 36 centimeters = 36 cm
B. 72 centimeters = 72 cm
C. 90 centimeters = 90 cm
D. 180 centimeters = 180 cm
Comparing these options to the calculated conversion, we can see that the best estimate of the number of centimeters in 1 yard is:
C. 90 centimeters
