A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts or red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?

Answers

Answer 1

Answer: add 2 more yellow

Step-by-step explanation:

use the ratio 7 to 2 to solve for 35 to x

[tex]\frac{7}{2} =\frac{35}{x} \\70=7x\\x=10[/tex]

for 35 quarts of red, you will need 10 quarts of yellow to keep the ration proportional. Since it has 8 parts yellow, you need to add 2 more yellow

Answer 2
You can fix the mixture to the correct shade of red by adding 2 more quarts of yellow since the ratio of red to yellow should be 7:2 when you times that ratio by 5 the correct amount to make the specific shade of red would be 35:10

If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107

Answers

Answer:

63

Step-by-step explanation:

F(x) = x² + 5x

F(5) = (5)² + 5(5) = 25 + 25 = 50

G(x) = 2x + 1

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.

Answer:

1/16

Step-by-step explanation:

The equation of a direct proportion is

y = kx

Let amount of fertilizer = y and amount of peat moss = x

We have x = 12 when y = 3/4

3/4 = k * 12

k = (3/4)/12 = 3/4 * 1/12 = 3/48 = 1/16

y = 1/16 x

The constant of proportionality is 1/16.

Which expression is equivalent to 3(4m - 2) - 2(m + 5)

A. 10m - 16

B. 14m + 4

C. -16m + 10

D. 12m - 6

Answers

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

~

Answer:

10 m - 16 (Answer A)

Step-by-step explanation:

We use distributive property to eliminate parenthesis:

12 m - 6 - 2 m -10

and now combine like terms:

[12 m - 2 m] - 6 - 10

10 m - 16

Therefore, answer option A.  is the correct one

Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

C. 210 sq cm.

30 • 5 = 150 sq cm (the total area of the long rectangles across)

12 • 5 = 60 sq cm
(no need to divide by 2 even if they are triangles because there are two on either side so they would cancel out)

150 + 60 = 210 sq cm.
