Answer:

27 muffins.

Step-by-step explanation:

We have been given that a baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold.

To find the number of muffins sold by noon let us find 45% of 60.

\text{The number of muffins sold by noon}=\frac{45}{100}\times 60

\text{The number of muffins sold by noon}=0.45\times 60

\text{The number of muffins sold by noon}=27

Therefore, 27 muffins were sold by noon.

Eric's chocolate bar is 56% cocoa. If the weight of the chocolate bar is 78 grams, how many grams of cocoa does it contain? Roun
alexgriva [62]

Answer:

The answer to your question is 43.7 g of chocolate

Step-by-step explanation:

Data

56% cocoa

mass of a chocolate bar = 78 g

Process

To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.

                          78 g of chocolate ------------------- 100%

                             x                          ------------------    56%

                                            x = (56 x 78) / 100

                                            x = 4368/100

                                            x = 43.68 g

-Round to the nearest tenth

             Mass of the chocolate = 43.7 g

In the geometric progression 1, 2, 4… what term is 512?
Levart [38]

The next term is double the previous term, so that the n-th term is given recursively by

\begin{cases}a_1=1\\a_n=2a_{n-1}&\text{for }n>1\end{cases}

This rule tells us that

a_2=2a_1

a_3=2a_2=2^2a_1

a_4=2a_3=2^3a_1

and so on, with the explicit rule

a_n=2^{n-1}a_1=2^{n-1}

for n\ge1.

If 512 is the k-th term in the sequence, then

512=2^{k-1}\implies\log_2512=\log_22^9=\log_22^{k-1}\implies9=k-1\implies k=10
