Calculate the percentage change (increase or decease) that occurs when:
SashulF [63]

The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.

So;

a)  change = Ι60 - 25Ι = 35.

     ratio of change to original = 35:25,

    multiplying by 100% will give 35/25 × 100% = 140%.

    Hence it is a 140% INCREASE.

b) change = | 30 - 66 | = 36

    the ratio is 36:66

multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%

   Hence it is a 54.5% DECREASE.

What is the percentage of cacao in hot chocolate which is made of 480 grams of milk and 20 grams of cacao?
galina1969 [7]

Given that the hot chocolate is made of 480 grams of milk and 20 grams of cacao.

We need to determine the percentage of cacao in hot chocolate.

<u>The percentage of cacao:</u>

The total grams of hot chocolate can be determined by adding the total grams of milk and the total grams of cacao.

Total grams of hot chocolate = Grams of Milk + Grams of cacao

Total grams of hot chocolate = 480 + 20 = 500 grams.

Thus, the total grams of hot chocolate is 500 grams.

Now, we shall find the percentage of cacao.

The percentage of cacao is given by

\frac{100}{500}\times 20

Simplifying, the values, we get,

\frac{2000}{500}=4\%

Thus, the percentage of cacao is 4%

Given the following formula, solve for t.<br> v = u + at
levacccp [35]

Answer:

t=(v-u)/a

Step-by-step explanation:

The equation we start with is v=u+at and we need to isolate t.

First subtract u from both sides

v-u=at

Now just divide both sides by a

(v-u)/a=t or t=(v-u)/a
