Answer:
5.05*10³
Step-by-step explanation:
-
<em>Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.</em>
- 5050 = 5.05 *1000 = 5.05*10³
Answer:
length of the arc = 6 units
Step-by-step explanation:
Answer:
CAD = 128
Step-by-step explanation:
CAD + CAB = DAB
We know that DAB is a straight line, so it equals 180 degrees
CAD + 52 = 180
Subtract 52 from each side
CAD +52-52 = 180-52
CAD = 128
<h3>
Answer: 280</h3>
Work Shown:
x = number of students in the 6th grade class
30% = 30/100 = 0.30
30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84
Divide both sides by 0.30 to isolate x
0.30x = 84
0.30x/0.30 = 84/0.30
x = 280
So there are 280 students overall in the 6th grade class.
