Step-by-step explanation:
Answer:
33.33 mL of 50%
66.67 of 80%
Step-by-step explanation:
Let x = quantity of 50% methane.
Then,
0.50x + 0.80(100 - x) = 100 × 0.70
⇒ 0.50 x + 80 - 0.80 x = 70
⇒ -0.30 x = 70 - 80
⇒ -0.30 x = -10
⇒ 
⇒ x = 33.33 mL of 50%
and, 100 - 33.33 = 66.67 of 80%
1.) move the constant over (1/2x=18-6) || 2.) combine like terms (1/2x=12) || 3.) divide both sides by 1/2 to get x alone (x=6)
Answer:
$5084745.76271
Step-by-step explanation:
Given data
Final amount= $6000000
Rate=6%
Time= 3 years
Now let us find the initial amount which is the principal
using the simple interest formula we have
6000000 = P(1+0.06*3)
6000000 =P(1+0.18)
6000000 =P*1.18
P= 6000000 /1.18
P=$5084745.76271
Hence the initial deposite is $5084745.76271
Answer:
The vertex is (-5,-1)
Step-by-step explanation:
f(x) = 4(x+5)²-1
This is written in vertex form
y = a(x-h)^2 +k where ( h,k) is the vertex
f(x) = 4(x- -5)²-1
H is -5 and k = -1
The vertex is (-5,-1)
