A chemist has two solutions: a 50% methane solution and an 80% methane solution. He wants 100 mL of a 70% methane solution. How
Likurg_2 [28]

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=\frac{10}{0.3}

⇒ x = 33.33 mL of 50%

and, 100 - 33.33 = 66.67 of 80%

Which of the following give the highest future value is 6000000 is invested at 6% for 3 years​
Blababa [14]

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

What is the vertex of the graph of f(x) = 4(x+5)²-1?​
vodomira [7]

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)
