Answer:

B(-2,5)

Step-by-step explanation:

Let B (x,y)

M = ([Xa+Xb]/2 , [Ya+Yb]/2)

(x+4)/2 = 1

x+4 = 2

x = 2-4

x = -2

(y+1)/2 = 3

y + 1 = 6

y = 6-1

y = 5

B (-2,5)

Monica [59]

Answer:

=1050 wildebeests

Step-by-step explanation:

We can form an arithmetic series for the wildebeest migration.

Sₙ=n/2(2a+(n-1)d) where  n is the number of terms, d is the common difference and a is the first term.

a=24

n=20

d=3

Sₙ=(20/2)(2(24)+(20-1)3)

Sₙ=10(48+57)

=1050 wildebeests

Problem of the Day:
Shtirlitz [24]

Answer:

Step-by-step explanation:

What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.

in order to find this we have to split each number into it's prime components.

for 12 they are 2,2 and 3 (

⋅

3

=

12

)

and for 15 they are 3 and 5 (

3

⋅

5

=

15

)

Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.

Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:

12

3

=

4

girls per group, and

15

3

=

5

boys per group.

(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [

A camel had to walk a distance of 11,040 m. After 4 hours, he still had to walk 920 m. How far did the camel walk per hour?
sergey [27]

He walked 2,525 m per an hour.

11,040 - 920 = 10,100

10,100 / 4 = 2,525
