Convert base 10 273 to a base 12

Margaret [11]

The highest power of 12 that divides 273 (with remainder) is $12^2=144$ , and dividing gives

$273=1(144)+129$

Divide the remainder term by the next highest power of 12, $12^1=12$ .

$129=10(12)+9$

So $273_{10}=1a9_{12}$ , since

$273=1\cdot144+10\cdot12+9\cdot1=1\cdot12^2+10\cdot12^1+9\cdot12^0$

Emily has the following grades in his math class: Homework grades: 80, 100, 90, Quiz grades: 84, 90, 72, Test grades: 64,

Bess [88]

Answer:

Step-by-step explanation:

Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9

Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5

Test mean x 45%: (64+72)/2 x 0.45 = 30.6

Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125

Zigmanuir [339]

Answer: 187.96 cm

Step-by-step explanation: First you need to convert all of the units into centimeters. To do this you need to convert the 6 feet into inches. Since there are 12 inches in a foot, 6 feet is equal to 72 inches. Next add the 2 inches to 72, and now this means Tyson is 74 inches tall. Lastly convert the inches into centimeters by multiplying 74 by 2.54, which equals 187.96.
