Monica is mixing some custom colored paint for her house. The color she wants requires 3/4 ounces of blue dye and 2/3 of an ounc

FrozenT [24]

Amount of blue dye mixed with one gallon of white paint= $\frac{3}{4}$

Amount needed for 8 gallons = $\frac{3}{4}\times8=6$ ounce

Amount of pink dye mixed with one gallon of white paint= $\frac{2}{3}$

Amount needed for 8 gallons = $\frac{2}{3}\times8= \frac{16}{3}$ ounces

So, total dye required = $6+\frac{16}{3}=\frac{18+16}{3}=\frac{34}{3}$

$11\frac{1}{3}$ ounces.

Hence, option C is correct.

The diagram below shows the graph of the quadratic function f (x) = ax² + 8x + c. calculate the value for each of the following.

Alexxandr [17]

Answer:

see explanation

Step-by-step explanation:

The y- intercept is at (0, 6) ⇒ c = 6

The x- coordinate of the vertex is at the midpoint of the zeros, that is

m = $\frac{-3-1}{2}$ = $\frac{-4}{2}$ = - 2

Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and

f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)

Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2

Thus

f(x) = 2x² + 8x + 6

Substitute m = - 2 into the equation for value of n

n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2

Hence

c = 6, m = - 2, a = 2, n = - 2

Which two kinds of whales have the closest number alive?

tangare [24]

The answer is: Fin whale and Sei whale.

The explanation for this exercise is shown below:

To solve this problem you must use the table given in the figure attached, which shows the numbers of whales alive today. In the column titled "Population" you can see these numbers.

Therefore, when you analize the table, you can conclude that the two kinds of whales that have the closest number alive are: Fin whale, with a population of 55,000 and Sei whale, with a population of 54,000.

A tank and a pail contained a total of 962 ml of water. When 250 ml of water was poured from the pail to the tank, the amount of

Allisa [31]

By solving a system of equations, we will see that the pail originally contained 382.9 ml.

<h3>How to write the system of equations?</h3>

First, we need to define the variables, we will use:

T = amount of water in the tank.
P = amount of water in the pail.

First, we know that the total amount of water is 962 ml, then we have:

P + T = 962 ml.

We also know that if we pour 250 ml from the pail to the tank, the amount of water in the tank will be 12 times the amount of water in the pail, this is written as:

T + 250ml = 12*(P - 250ml)

Then the system of equations is:

P + T = 962 ml

T + 250ml = 12*(P - 250ml)

To solve this, first, we need to isolate one of the variables in one of the equations, I will isolate T in the first one:

T = 962 ml - P

Now we replace this into the other equation to get:

(962 ml - P) + 250ml = 12*(P - 250ml)

Now we can solve this for P.

962 ml + 250 ml - P = 12*P - 12*250 ml

1,212 ml - P = 12*P - 3,000 ml

1,212 ml + 3,000 ml = 12*P - P

(4,212 ml)/11 = P = 382.9 ml

So the pail originally contained 382.9 ml
