Answer:
530.66 square cm
Step-by-step explanation:
A=pi*r^2
A=pi*13^2
A=530.66
The slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.
<h3>What is the slope-intercept form of the given equation?</h3>
The slope-intercept form is expressed as;
y = mx + b
Where m is the slope and b is the y-intercept.
Given the equation in the question;
8x + 10y = -30
To convert to slope intercept form, we make y the subject of the formula and simplify.
8x + 10y = -30
10y = -8x - 30
Divide each term by 10
10y/10 = -8x/10 - 30/10
y = -4x/5 - 3
y = (-4/5)x - 3
Therefore, the slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

Step-by-step explanation:
Pretty sure x is 90 and y is 43.
Answer:
7.1 miles
Step-by-step explanation:
From the park to the library is a diagonal line. We can use pythagorean theorem.
Change in y - 7
Change in x - 1
7^2 + 1^2 = x^2
(x is the distance between the library and park)
49 + 1 = x^2
50 = x^2
That's around 7.
