Step-by-step explanation:
Answer: 63 nurses and 14 doctors
so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.
if theres 9 (9*1) nurses theres 2 (2*1) doctors
if theres 18 (9*2) nurses theres 4 (2*2) doctors
if theres 27 (9*3) nurses theres 6 (2*3) doctors
you get the point so i multiplied 7 to 9 and 7 to 2, which means:
if theres 63 (9*7) nurses theres 14 (2*7) doctors
i hope this helps :)
Note the place values:
9 ones place value
. (decimal point)
3 tenths place value
4 hundredths place value
8 thousandths place value
8 ten thousandths place value
You are solving for the tenth place value. Look at the digit directly right of the tenths place value. It is the hundredths place value, which is 4.
Note that when rounding, if the number next to what you are solving for, has a value of 5 or greater, you round up. If it has a value of 4 and less, you round down. In this case, it is a 4, so round down.
9.3488 rounded to the nearest tenth is 9.3
9.3 is your answer.
Answer:
Solution,
base=1
perpendicular=?
hypotenuse=X
now,
using Pythagoras theorem,
x^2=p^2+b^2
or, x^2=p^2+1^2
or,p^2=x^2-1
or, p=√x^2-1
tan theta=perpendicular/ base
tan theta =√x^2-1/1
tan theta=√x^2-1
z=tan theta
z=√x^2-1
Hope this helps...
Good luck on your assignment..
Your answe would be a>-2 so just plug that in to the line and that will be your answer which is the second one
