Answer:
Using the Pythagorean Theorem:
distance^2 = 72^2 + 65^2
distance^2 = 5,184 + 4,225
distance^2 = 9,409
distance = 97 yards
"round-trip" distance = 97 * 2 = 194 yards
Step-by-step explanation:
Chance has 90.72 grams in coins
Answer:
0
Step-by-step explanation:
It is not permissible for the denominator to be zero, so the "nonpermissible replacement" for x is 0.
10(x-5)=-80
10x-50=-80
+50 +50
10x=-30
/10 /10
x=-3
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
