There are 22 animals in the barn. Some are geese and some are goats. There are 82 legs in all. How many of each animal are there

Free_Kalibri [48]

Let the number of geese be x.

Then number of goats is 22-x.

A goose has 2 legs, and a goat has 4.

There are a total of 82 legs.

So,

2x + 4(22-x) = 82

2x + 88 - 4x = 82

-2x = -6

x = 3

There are 3 geese and (22-3=) 19 goats.

A cat chases a mouse. The cat is originally 4 feet behind the mouse, which is running in the same direction along the same route

Darya [45]

The cat will take 0.8 seconds to catch up with the mouse

Step-by-step explanation:

Given:

The distance between the cat and the mouse = 4 feet

cat's speed = 17 feet per second.

mouse's speed = 12 feet per second

To Find:

how long will it take the cat to catch up with the mouse = ?

Solution:

We know that

distance = speed x time

Rewriting the equation for time we get

time = $\frac{distance }{speed}$

now we know that distance is 4 feet

and the speed is 17 -12 = 5 feet per second

Thus the time is

= $\frac{4}{5}$

= 0.8 seconds

The line CD passes through the points C (2, -1) and D (1, 1). Which of the

inn [45]

Answer:

<em>The equation of the straight line in point - slope form</em>

<em>y +1 = -2 ( x-2)</em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given points are C( 2,-1) and D(1,1)

Slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{1-(-1)}{1-2} = \frac{2}{-1} = -2$

m = -2

<u>Step(ii):-</u>

Equation of the straight line passing through the point ( 2,-1) and having slope

m =-2

y - y₁ = m ( x- x₁)

y - (-1) = -2 ( x-2)

y +1 = -2 ( x-2)

<u><em>Final answer:-</em></u>

<em>The equation of the straight line</em>

<em>y +1 = -2 ( x-2)</em>
