Answer:
A. 5
Step-by-step explanation:
because 13 is the hypotenuse and 8 is the sine
The answer is 296 because you do 74*400 which equals 29,600 then divide by 100 and get 296.
A = (pi) * r*2
(pi) = 3.14
r = d/2.....r = 17/2 or 8.5
A = 3.14 * 8.5^2
A = 3.14 * 72.25
A = 226.86 rounds to 226.9 m^2 <==
Answer:
the equation is
x - 4 = - 9
the number is
-5
Step-by-step explanation:
First, we don't know the number so we represent it with a variable like "x".
then difference simply means subtraction.
" is" simply means = ( equal to)
so the question says that difference of 4 and a number is 9 so we have x - 4 = -9
so now let's solve for x
we group liked terms and make x stand alone.
x = -9 + 4
( +4 because it crossed an equal sign)
x = - 5
we have
x = -5
so we can substitute the -5 into the equation to if its true
from the equation x - 4 = - 9
where we put -5 instead of x
-5 - 4 = - 9
