Answer :
the answer is -4/5 or -0.8
step-by-step explanation:
1-9/7+3 = -8/10
now simplify that,
-8/2 = -4
10/2 = 5
so we have -4/5 0r -0.8
Answer:
with sausage-330
without-165
Step-by-step explanation:
so key words are <u>with</u> sausage was <u>half</u><u> </u>that <u>without</u>
so let's say the ones with sausage are x
and therefore the ones without are 1/2x
but all are equal to 495
so x+1/2x=495
1.5x=495
x/with a sausage=330
1/2x/without a sausage=330/2=165
Step-by-step explanation:
Equation 1
Equation 2
Using the cosine theorem we have the following equation:
d ^ 2 = (800) ^ 2 + (840) ^ 2 - 2 * (800) * (840) * (cos (150-45))
We cleared d:
d = root ((800) ^ 2 + (840) ^ 2 - 2 * (800) * (840) * (cos (150-45)))
d = 1301.327321
Nearest whole number:
d = 1301 miles
Answer:
The airplanes are far about:
d = 1301 miles
