3/8 to 7/8 find the percent of change and is it decrease or increase

mote1985 [20]

Answer:133.33%

Step-by-step explanation:

For given change in fractions from $\frac{3}{8}$ to $\frac{7}{8}$

The initial fraction= $\frac{3}{8}$

New fraction= $\frac{7}{8}$

Change in fractions= New fraction-Initial fraction

$=\frac{7}{8}-\frac{3}{8}\\\\=\frac{7-3}{8}\\\\=\frac{4}{8}\\=\frac{1}{2}$

As change in fraction is positive thus it is an increase.

$\text{Percent of increase=}\frac{\text{increase in fraction}}{\text{initial fraction}}\times100\\\\=\frac{\frac{1}{2}}{\frac{3}{8}}\times100\\\\=\frac{1}{2}\times\frac{8}{3}\times100\\\\=\frac{400}{3}=133.33\%$

Modern computers are built using the principle of Hierarchical layers of abstraction. Explain Hierarchical layers of abstraction

bearhunter [10]

Answer:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.

Step-by-step explanation:

Hierarchical layers of abstraction in computers:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate platform independence.

In Hierarchical layers, users work independently at each level of the hierarchy.

example:

Abstraction in computing is language abstraction

Development of programming languages from machine language to assembly language and then high-level language is an example of Hierarchical layers of abstraction. Here each stage is a base for the next stage.

4. Tikili wants to invest $3500 at her local bank. She will receive an interest rate of 5% compounded

alexandr402 [8]

Answer:

$3863.35 = 3500(1 + \frac{0.05}{2} )^{(2 \times 2)}$

Step-by-step explanation:

The formula for this equation is

$a = p(1 + \frac{r}{n} )^{(n \times t)}$

a is the final result

p is the starting amount (deposited)

r is the interest rate

n is the number of times it's compounded

t is the time

because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117

Please double check me I may be wrong, this is my second time doing these type of questions
