Answer:

  • <u><em>The ratio of the number of flour tortillas to the total number of tortillas is: 6:10, which is equivalent to 3:5.</em></u>

<u><em></em></u>

Explanation:

First, let's make clear that the correct wording is that the ratio of the number of corn tortillas to the number of flour tortillas is 4:6.

From that, you must determine the ratio of the number of flour tortillas to the total number of tortillas.

You can do it with the help of a chart that you can build from the ratio of the number of corn tortillas to to the number of flour tortillas:

       # Corn tortillas       # Flour tortillas       #Total tortillas

                 4                               6                           10

Now, the ratio of the number of flour tortillas to the number of total tortillas is:

  • Ratio of the numberr of flour tortillas to the total number of tortillas, r:

              r =  # flour tortillas / # total tortillas = 6:10

That ratio may be simplified by dividing by the greatest common divisor of 6 and 10, which is 2:

  • Ratio = 6:10 = 3:5.

Pure copper was mixed with a 10% copper alloy to produce an alloy thát was 25% copper. How much of the pure copper and how much
lora16 [44]

Answer:

6kg pure copper and 30 kg 10% copper was mixed to give 36kg of 25% alloy

Step-by-step explanation:

Here, we want to produce 36 kg of 25% alloy

Let the Pure copper be x kg while 10% alloy be y kg

Pure copper is simply 100% copper

Thus;

x + y = 36 •••••(i)

Then;

100% of x + 10% of y = 25% of 36

= x + 0.1y = 9 •••••• ii)

From i x = 36-y

from ii, x = 9-0.1y

Equate both x

36-y = 9-0.1y

36-9 = 0.1y + y

0.9y = 27

y = 27/0.9

y = 30

x = 36-y

x = 36-30

x = 6 kg

Gina is a certain age (g). Gina's older sister is twice Gina's age. Gina's brother is half Gina's age. The sum of their ages is
aliina [53]

Answer:

Gina is 12 years old

Step-by-step explanation:

First,  we will have to write these statements mathematically and then solve.

Let Gina's age be x, let Gina's brother's age be y and let Gina's sister's age be z.

The second statement"Gina's older sister is twice Gina's age" can be mathematically written as: z =2 x ---------------------------(1)

The next statement "Gina's brother is half Gina's age" can be mathematically written as y = \frac{x}{2} ---------------------------------------(2)

Then the next statement "the sum of their ages is 42" can be mathematically written as: x + y + z = 42 ----------------------------(3)

We can now proceed to solve;

Substitute equation (1) and equation(2) into equation (3)

x + y + z = 42

x +  \frac{x}{2} + 2x = 42

Multiply through by 2

2x + x + 4x = 84

7x = 84

Divide both-side of the equation by 7

\frac{7x}{7} = \frac{84}{7}

x = 12

Therefore, Gina is 12 years old
