B. Each game lasts 30 minutes
all you care about is how many teams you can form
Answer:
there are 114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.
Answer:
D
Step-by-step explanation:
first find the perimeter of both triangles
Original perimeter: 72 in
scaled perimeter: 24 in
A is wrong since the scaled perimeter is actually smaller.
B is wrong because its not 6 times smaller
C is wrong since it's not 1/9 of the original
D is correct since the scaled is a 1/3 of the original perimeter (72*1/3 = 24)
Answer:
The coordinates of N are (-3,-8)
Step-by-step explanation:
Here, we are going to use the internal division to find the coordinates of the point split the line segment MP in the ratio 3:4
Mathematically, that would be;
(x,y) = (nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
we have;
m = 3 and n = 4
M is (x1,y1) while N is (x2,y2)
we have;
(x,y) = (4(-12) + 3(9))/(3+4) , (4(-5) + 3(-12))/(3+4)
(x,y) = (-48 + 27)/7, (-20 -36)/7
(x,y) = (-21/7 , -56/7)
(x,y) = (-3,-8)
The answer is 90. Hope this helps
