A 3% salt solution weighing 100g represents 100g of water in which 3g of salt is dissolved (=3/10). What amount of salt would be
Nadya [2.5K]

Answer:

There would be 12 g of salt (12.3 g actually but rounded) and 88g of water (88.7 g actually but rounded)

Step-by-step explanation:

From the question, a 14% salt solution means 14g of salt in 100g of water.

What this means is that, the fraction of salt to water in the solution would be 14/100 which is same as 7/50

Now, we want to know the amount of salt and the amount of water in a 100g of 14% salt solution.

Looking at the ratio salt to water, we have 7 to 50

For every 50 parts of water, there are 7 parts of salt.

So the ratio of both is 7:50

For salt, the amount in grammes present will be ;

7/(50 + 7) * 100g = 7/57 * 100 = 12.3 g or 12g to the nearest whole number

The amount in grammes of water present will be ;

50/(50 + 7) * 100g = 50/57 * 100 = 87.7g or 88g to the nearest whole number

One leg of a 45 - 45 - 90 triangle measures 12 centimeters what is the length of the hypotenuse
adelina 88 [10]
The angles of the triangle are given as to have measures of 45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:

c² = a² + b²

c² = 2a²

4² = 2a²

a = 2√2

Hope this answers the question.

The smaller rectangle is a 1/2 scale drawing of the original figure. Use the drop-down menus to show the missing dimensions of t
MAXImum [283]

Answer:

L1 = 18 cm

W1 = 14 cm

A1 = 252 cm²

Step-by-step explanation:

Since the small rectangle is ½ the scale drawing of the original figure, therefore the dimensions of the smaller rectangle would be half of that of the original.

Thus:

Length (L) of the original = 36 cm

Length (L1) of the smaller rectangle = ½(36) = 18 cm

Width (W) of the original = 28 cm

Length (W1) of the smaller rectangle = ½(28) = 14 cm

Area (A1) of the smaller rectangle = L1 × W1 = 18 × 14 = 252 cm²

Of the 420 students enrolled in basic math only 41% are first-year students. How many
Luba_88 [7]

Answer:

Step-by-step explanation:

There are 420 students.

41% are first year students.

41% = 41/100

420 * 41/100 = 172.4

What do you do about the 0.4? I would just round to the nearest whole number which is 172.

There are 420 - 172 = 248 who are not first year students.
