Answer:
y=1/2x+5/2
Step-by-step explanation:
expand the point-slope form and rearrange to y=mx+b
y-3=1/2(x-1)
y-3=1/2x-1/2
y=1/2x+5/2
She would have 4/5 dog toys that are left. So about 40 dog toys.
Hope this would work and help!

The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:

From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:

Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation
. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
Answer:
14.1 feet
Step-by-step explanation:
Draw a diagram to get a triangle, and label it. use the pythagorean theorem, a^2+b^2=c^2
Lol I’m taking the same stuff right now. Sorry to be but no cheating on homework. The formulas are long but you’ll get there
