Represent
r=number of rabbits
c=number of chickens
1 rabbit=4 feet and 1 head
1 chicen=2 feet and 1 head

rabbits head+chicen heads=72
1r+1c=72
feet=200
4 times r+2 times c=200
4r+2c=200
divide both sides by 2
2r+c=100


we have
r+c=72
2r+c=100
make first equation negative and add to second equation

-r-c=-72
<u>2r+c=100 +
</u>1r+0c=28

r=28
subsitute
r+c=72
28+c=72
subtract 28
c=44

44 chickens and 28 rabits

<h3>Answer: B. (40,40)</h3>

Explanation:

<u>Given Inequalities</u>:

(i) 3x + 8y ≤ 480

(ii) y - x ≤ 20

For first inequality:

(a) y intercept: (0, 60)

(b) x intercept: (160, 0)

  • Plot this line with a solid line and shade below.

For second inequality:

(a) y intercept: (0, 20)

(b) x intercept: (-20, 0)

  • Plot this line with a solid line and shade below.

The point (40, 40) falls between these two inequalities.

Find the value of y.
Alexandra [31]

Answer. First option: -1

Solution:

We have a triangle, and we know two angles of 60° each one. We can find the third angle A, using:

A+B+C=180°, with B=60° and C=60°:

A+60°+60°=180°

Solving for A: Adding similar terms:

A+120°=180°

Subtracting 120° both sides of the equation:

A+120°-120°=180°-120°

A=60°

The third angle A is 60° too, then the triangle has three equal angles of 60° each one, and it is an equillateral triangle, thus its three sides must be congruents:

2y+6=4=2x-3

We need to find the value of y, then using the first equality:

2y+6=4

Solving for y: Subtracting 6 both sides of the equation:

2y+6-6=4-6

2y=-2

Diniding both sides of the equation by 2:

2y/2=-2/2

y=-1

Alyssa is jogging near Central Park. She runs along 65th Street for about 0.19 miles, then turns right and runs along Central Pa
Kryger [21]

Answer:

Her total run is 0.81 miles.

Step-by-step explanation:

Consider the provided information.

The provided information can be visualized by the figure 1.

The path she covers represent a right angle triangle, where the length of two legs are given as 0.19 and 0.28.

Use the Pythagorean theorem to find the length of missing side.

a^2+b^2=c^2

Where, <em>a</em> and <em>b</em> are the legs and <em>c</em> is the hypotenuse of the right angle triangle.

The provided lengths are 0.19 and 0.28.

Now, calculate the missing side.

(0.19)^2+(0.28)^2=(c)^2

0.0361+0.784=(c)^2

0.1145=c^2

\sqrt{0.1145}=c

c\approx{0.34}

Thus, the total distance is:

0.34 + 0.19 + 0.28 = 0.81

Therefore, her total run is 0.81 miles.
