How many milliliters of 0.30% sugar solution must you add to 75mL of 4% sugar solution to get a 0.50% sugar solution?
hammer [34]
Based on the given data above, the equation below has been generated,
(X mL)(0.003) + 75 mL (0.04) = 0.005 (75 + X); X being the amount in mL of the sugar solution, by further simplification of the generated equation, it can be said that 1312.5 mL of 0.30% sugar solution should be added to 75 mL of 4% solution to come up with a 0.5% sugar solution.

Health club a charges 100.00 membership fee plus 25.00 per plus 25.00 per month
Snowcat [4.5K]

Answer:

Month 5 the cost will be the same

Step-by-step explanation:

Make to equations from the given information

Let y be the cost, and let x be the number of months

Club A:  y = 25x + 100

Club B:  y = 20x + 200

It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..

25x + 100 = 20x + 200

5x = 100              (subtract 20x and 100 from both sides)

  x = 20                (divide both sides by 5)

So after 5 months the cost will be equal,

Find the missing length indicated <br> A) 25<br> B) 5<br> C) 8<br> D) 3
Nonamiya [84]

Given:

The figure of a triangle.

To find:

The missing length.

Solution:

Let x be the missing length.

Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.

Using Basic proportionality theorem, we get

\dfrac{6}{8-6}=\dfrac{12-x}{x}

\dfrac{6}{2}=\dfrac{12-x}{x}

3=\dfrac{12-x}{x}

3x=12-x

Adding x on both sides, we get

3x+x=12

4x=12

x=\dfrac{12}{4}

x=3

The missing length is 3 Therefore, the correct option is D.
