Answer:
115
Step-by-step explanation:
angle DEF is an inscribed angle and arc DF is the arc it intercepts
if you didn't know an inscribed angle is equal to half the measure of the arc it intercepts
Hence angle DEF = 1/2 of arc DF
If arc DF = 230 then angle DEF = half of 230 or 230/2
230/2=115
Hence angle DEF = 115

Answer:
$50.44
Step-by-step explanation:
First I turned the percent to a decimal which was 0.15.
Then I multiplied 0.15* 43.86
The answer was 50.439 so then I rounded it to 50.44
Answer: $50.44
Here, we need to write the length of the insect in scientific notation.
The given length of the insect is 0.0052 meter
Now, to write 0.0052 meter in scientific notation we need to follow this:
Scientific notation always start with non-zero digit followed by a decimal point.
Since in our number the decimal is needed to be moved three places to the right to get the first non-zero digit.
The exponent of the 10 is
.

Therefore, our number 0.0052 can be written as:

Hence, the require scientific notation is
.
