How much water should we add to 35kg of sugar syrup to change it's concentration from 30% to 25%
agasfer [191]

Answer:

Water = 1/5 of the volume of the syrup

Step-by-.step explanation:

Suppose we had  1000 cm^3 of syrup  and the new volume after adding water is x cm^3.  Now the amount of sugar stays the same so we have the equation 35 * 1000 =  25 * x

x = (30 * 1000) / 25 =  30,000 / 25

= 1200 cm^3

So we need to add 200 cm^2 of water .

In general terms,  we need to add water which equals 1/5 of the volume of the syrup,

Help please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ghella [55]

Answer:

  4.7 yd

Step-by-step explanation:

The horizontal lines in the diagram are parallel, so the angle of depression at D and the angle of elevation at F are congruent. So, you have a right triangle with the measure of one acute angle (F) and the length of the adjacent side (EF = 10 yd). You are being asked to find the opposite side (DE).

The mnemonic SOH CAH TOA reminds you of the necessary relation:

  Tan = Opposite/Adjacent

Filling in the given information, you have ...

  tan(25°) = DE/(10 yd)

Multiplying by 10 yd gives ...

  (10 yd)tan(25°) = DE ≈ 4.663 yd ≈ 4.7 yd

Find the rate of change for each set of ordered pairs. What is the average rate of change of all the sets?
valina [46]

Answer:

Rate of change for two ordered -pairs i,e (x_1, y_1) and (x_2, y_2) is given by;

\text{Rate of change} = \frac{y_2-y_1}{x_2-x_1}

1.

(-1, 12) and (6, 26)

Then;

\text{Rate of change} = \frac{26-12}{6-(-1)}

or

\text{Rate of change}(A) = \frac{14}{7} =2

2.

(-1, -9) and (3, 3)

Then;

\text{Rate of change} = \frac{3-(-9)}{3-(-1)}

or

\text{Rate of change}(B) = \frac{12}{4} =3

3.

(12, 6) and (11, 13)

Then;

\text{Rate of change} = \frac{13-6}{11-12}

or

\text{Rate of change}(C) = \frac{7}{-1} =-7

Now, find the average rate of change of all the sets:

Average defined as the sum of all the observation to the number of observation.

\text{Average rate of change of all sets} =\frac{A+B+C}{3} =\frac{2+3-7}{3} = -\frac{2}{3}
