Assuming 6.5×10^3 5.5×10^5 1.1×10^3
are in scientific notation.
6500
550000
1100
are the choices without scientific notation.
so by looking at this you can assume (E) is the right answer
(E) <span>The greatest number is 5.5 × 105. It is 5,000 times greater than the smallest number.</span>
Answer:
I think it's option B ...
Answer:
The correct answer is 47 degrees.
Step-by-step explanation:
Use cosine.
cos(x)= adj/hyp
cos(x)=19/28
x=arccos(19/28)
Use a calculator
x is approximately 47 degrees.
Total measure is 180
x is 2nd and y is 3rd angle
2nd is 4 times 3rd angle
x=4y
total is 180
20+x+y=180
x=4y
20+4y+y=180
20+5y=180
minus 20 both sides
5y=160
divide by 5
y=32
third angle is 32 degrees
Answer:
30
Step-by-step explanation:
40 divided by 4 is 10 and since 100 divided by 4 is 25 then multiple each by 3
