Note:

We can solve using proportionality.

Given:

200 beads cost $48.

For 25 beads, cost is x.

Calculation:

Set up proportion: 200/48 = 25/x, then cross-multiply.

200x = 48 × 25

200x = 1200

Divide both sides by 200:

x = 1200 / 200

x equals 6 dollars Final answer

For every 1 litre of water used to make a medicine, 300 ml of sucrose and 750ml of saline solution are used. Express the amount
PIT_PIT [3919]

Answer: The ratio needed will be 20:6:15.

Step-by-step explanation:

Given that

For every 1 liter of water used to create the medicine, 300 ml of sucrose and 750 ml of saline solution are required.

We should simplify the quantities of water, sucrose, and saline solution to their lowest terms.

All amounts should be converted to the same unit, which is ml.

As per the information provided,

1\ liter=1000\ milimeter\\

Thus, the ratio will be expressed as

\text{Amount of water: Sucrose: saline solution}\\\\=1000:300:750\\\\=200:60:150\\\\=40:12:30\\\\=20:6:15

Consequently, the required ratio is 20:6:15.

-3x + 2c = -3, solve for x
zzz [4022]

Answer:

x=2c/3+1

Step-by-step explanation:

First, subtract 2c from both sides.

−3x=−3−2c

The equation has been transformed into standard form.

−3x=−2c−3

Next, divide both sides by −3.

-3x/-3=-2c-3/-3

Dividing by −3 negates the multiplication by −3.

x=-2c-3/-3

Finally, divide −3−2c by −3.

x=2c/3+1

Data obtained from a nominal scale: A. must be alphabetic B. can be either numeric or nonnumeric C. must be numeric D. must rank
Leona [4166]

Answer:

Choice B

Step-by-step explanation:

The information given falls under the nominal scale of measurement since classifications can be made into distinct groups. For instance, students might be sorted into categories based on their eye colors. Even numerical codes can be used within the nominal scale for grouping; for example, assigning numbers 1, 2, and 3 for students with brown, black, and green eyes, respectively. However, these numbers do not hold any numerical weight. Therefore, data from a nominal scale may be numeric or non-numeric.
