We know 20% is 15
and now we find 80%

since 20% x 4 = 80%, we can multiply 15 by 4 to get 80% of 75

15 x 4 = 60

80% of 75 = 60

What are the last two digits of 7^1867? ​
Kipish [7]

Considering that the powers of 7 follow a pattern, it is found that the last two digits of 7^{1867} are 43.

<h3>What is the powers of 7 pattern?</h3>

The last two digits of a power of 7 will always follow the following pattern: {07, 49, 43, 01}, which means that, for 7^n, we have to look at the remainder of the division by 4:

  • If the remainder is of 1, the last two digits are 07.
  • If the remainder is of 2, the last two digits are 49.
  • If the remainder is of 3, the last two digits are 43.
  • If the remainder is of 0, the last two digits are 01.

In this problem, we have that n = 1867, and the remainder of the division of 1867 by 4 is of 3, hence the last two digits of 7^{1867} are 43.

Blueberry high-fiber muffins contain 51 % dietary fiber by mass. If a package with a net weight of 18 oz contains six muffins, h
8_murik_8 [283]

Answer:

In each muffin there are 1.53oz

Step-by-step explanation:

The first step is to get the weight of just one muffin. If the package contains six muffins we must divide the total weight by six.

weight_{unit}=\frac{18oz}{6}=3oz

The weight of just one muffin is 3oz.

Now, the problem says that blueberry high-fiber muffins contain 51 % dietary fiber by mass, which means that we must calculate the 51% of 3oz. We must take into account that 51% equals 51/100 which is 0.51. The equation would be:

fiber=(3oz)(0.51)=1.53oz

Finally, in each muffin there are 1.53oz of fiber.
