-1 1/5 + -3/5 in simplest form

Answers

Answer:

-1 4/5

Step-by-step explanation:

In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3 5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

A bird with a mass of 1.5 kg flies at a rate of 4.0 m/s. What is the kinetic energy of the bird?

Answers

The answer is 12 J.

The kinetic energy (KE) of an object is expressed as the product of half of the mass (m) of the object and the square of its velocity (v²):
$KE = (1)/(2) m*v^(2)$

The unit of the kinetic energy is Joules (J = kg · (m/s)²).

It is given:
m = 1.5 kg
v = 4 m/s

It is unknown:
KE = ?

Thus:
$KE = (1)/(2) m*v^(2)$
$KE = (1)/(2) 1.5kg*(4 m/s)^(2)$
$KE = 0.75kg*16(m/s)^(2)$
$KE = 12 kg*(m/s)^(2)$
$KE = 12J$

Therefore, the kinetic energy of the bird is 12J.

Answer:

12J

Karey is prescribed 600 mg of a medication that decays at a rate of 40% per day, d, according to the equation

Answers

Answer : 7.8%

Karey is prescribed 600 mg of a medication that decays at a rate of 40% per day, d, according to the equation

$m=600(0.6)^d$

Noelle takes same amount before 5 days.

Amount of medication remain in Nelle's body is

$m=600(0.6)^5 = 46.656$

Karey is prescribed 600 mg of a medication

We need to find out what percentage of 46.656 in 600

$(46.656)/(600) =0.07776$

Now multiply it by 100 to get percentage

0.07776 * 100 = 7.8%
