2015 i was 4 feet 2 inches, and in 2016 i grew to 4 feet and 5 inches, what was the percent increase from 2015 to 2017.

Graph the equation to solve the system. y=2x+7 1/2y=x+7/2

vlabodo [156]

Given equation is y=2x+7 and $\frac{1}{2}y=x+\frac{7}{2}$

Let's simplify the 2nd equation $\frac{1}{2}y=x+\frac{7}{2}$ before we can start graph so that calculation will be easy

$\frac{1}{2}y=x+\frac{7}{2}$

multiply both sides by 2 to cancel out fractions

$2*\frac{1}{2}y=2*x+2*\frac{7}{2}$

y=2x+7

which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.

y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

If money in a savings account earned 8% interest per annum, how much nterest would be earned on $150.00 over three years?

Pani-rosa [81]

Answer:

$36

Step-by-step explanation:

Given :

Interest rate, r = 8% = 0.08

Principal, P = 150

Time, t = 3 years

Simple interest = (principal * rate * time)

Simple interest = (150 * 0.08 * 3)

Simple interest = $36

monarch butterflies migrates when they sense daylight hours are shorter and temperature get colder.write two equivalent fraction

Tpy6a [65]

Two equivalent fractions to represent the part of the migration a monarch butterfly can complete in 1 week is $\frac{5}{25}$ or $\frac{1}{5}$ .

<h3>What is a fraction?</h3>

A fraction is a mathematical expression that shows the relationship between parts vs total. In a fraction, the part is written first and it is known as the numerator. On the other hand, the total is written below and it is known as the denominator.

<h3>How to write a fraction?</h3>

Here are the steps to write a fraction:

Find the total.
Find the part.
Write the fraction.

Based on this, in the chart, the part of the migration these butterflies can complete in a week are the squares in green, while the total is the total squares. This means the fraction for this situation is:
