Step 1
Formulate a recursive sequence modeling the number of grams after n minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829
a(n) = 780*[0.829<span>^n]
</span>
for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g
the answer is 22.1 g
<span>Prime factorization of 140/700 = </span>Answer: 140/700 =1/5 = 0.2
Answer:
pic?
Step-by-step explanation:
To subtract a number from another number, they must be the same type. 4 1/4 is a mixed number; 3/4 is a fraction. thus, 4 1/4 must be converted into fractional form go subract a fraction (3/4) from it.
x = 8, y = 0
y=
x-4
y=-
x+2
We substitute y=x-4 into the y for y=-x+2, and we get:
x-4 = -x+2
+x +x
x -4 = 2
+4 +4
x = 6
(4)x = 6 (4)
The 4's cross out and we get:
3x = 24
/3 /3
x=8
Not we substitute x(8) into one of our original equations: y=x-4
y=x-4
y=(8)-4
y=4-4
y-0
We get our final answer: (8,0)
Hope that helps!
