Answer: 1

Step-by-step explanation:

Total number of students that own hamsters 16+25 = 41.

Total of students that own dogs 16+24 = 40.

That is 41-40 = 1.

Good luck

Write the standard form of the equation of the line through the given point with the given slope. Through (-2,5), slope =-4

Answer:

$\huge\boxed{4x+y=-3}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

(x₁, y₁) - point on a line

m - slope

We have

$m=-4,\ (-2,\ 5)\to x_1=-2,\ y_1=5$

Substitute:

$y-5=-4(x-(-2))\\\\y-5=-4(x+2)$

Convert to the standard form

$Ax+By=C$

$y-5=-4(x+2)$ use the distributive property

$y-5=(-4)(x)+(-4)(2)$

$y-5=-4x-8$ add 5 to both sides

$y-5+5=-4x-8+5$

$y=-4x-3$ add 4x to both sides

$4x+y=-4x+4x-3\\\\4x+y=-3$

Answer:

C = 314 meters

Step-by-step explanation:

When we go around a circle, we are trying to find the circumference

The circumference is

C= pi *d

C = pi *100

Let pi = 3.14

C = 3.14*100

C = 314 meters
