<u>The answer in English</u>

A goat has been tied with a rope 15 m long, in one of the corners of a rectangular meadow 20x30 m. Calculate the surface of the meadow on which the goat can graze.

we know that

the surface of the meadow on which the goat can graze is a quarter of a circle

the area of the surface of the meadow is equal to

A= \frac{1}{4} * \pi *r^{2}

where

r=15 m

substitute

A= \frac{1}{4} * \pi *15^{2}

A= 176.71 \ m^{2}

therefore

<u>the answer is</u>

the area of the surface of the meadow on which the goat can graze is 176.71 \ m^{2}

<u>The answer in Spanish</u>

Sabemos que

la superficie del prado en el que se puede pastar la cabra  es igual al area de un cuarto de circulo

El area de la superficie del prado es igual a

A= \frac{1}{4} * \pi *r^{2}

donde

r=15 m

sustituya

A= \frac{1}{4} * \pi *15^{2}

A= 176.71 \ m^{2}

por lo tanto

<u>La respuesta es</u>

El area de la superficie del prado en el que se puede pastar la cabra  es igual 176.71 \ m^{2}

Jewelery maker has
24 jade beads
30 teak Beads
So we need to find the highest common factor for both 24 and 30
The factors for both numbers are
24 -1,2,3,4,6,8,12,24
30 - 1,2,3,5,6,10,15,30
The highest common factor for both is 6
The greatest number of necklaces she can make is 6
Number of jade beads - 24/6 = 4 jade beads
Number of teak beads - 30/6 = 5 teak beads
So each necklace will have 4 jade beads and 5 teak beads

Step-by-step explanation:

midpoint ((x1+x2)/2, (y1+y2)/2)

Let S be (x,y(

(0+x)/2=2, solve for x, x=4

(4+y)/2=-8, solve for y, y=-20
