You receive two quarters, one dime, and four pennies back in change. Write the amount as a fraction in simplest form

Ahat [919]

$\frac{50}{100} = \frac{2}{4} = \frac{1}{2}$
$\frac{10}{100} = \frac{1}{10}$
$\frac{4}{100} = \frac{2}{50} = \frac{1}{25}$
$\frac{1}{2} = .50$
$\frac{1}{25} = .04$
$\frac{1}{10} = .10$

Answer:

The one opposite of 100°, as the bigger the angle, the bigger the opposing side, is the biggest.

By the same logic, the one opposite 45° is the next biggest.

Continuing with that, the one opposite the black one (which would equal 35°, I think) is the smallest.

Answer:

The equation of the line is $y = 3x + 3$

Step-by-step explanation:

Looks like you've already found the y-intercept and slope of this graph. Great! That's all the info we need to create an equation.

The equation of a line is always in $y = kx+b$ form, where k is the constant of proportionality (aka the slope) and b is the constant added (aka the y-intercept).

We know the slope is 3 and the y-intercept is 3, so we can put these values into the equation.

$y = 3x+3$

Hope this helped!
