Answer:
35 will be the students and 52 will be the parents
Step-by-step explanation:
Multiply 35 with 2.75 =96.25
Multiply 52 with 3.50=182
182+96.25=278.25
Well you'd use the distance formula for each pair of points:
d = sq.root of((x2 - x1)^2 + (y2-y1)^2)
(1) For the points (-5,6) and (-5,-2):
d = sq.root of((-5-(-5))^2 + (-2-6)^2)
= sq.root of (0 + 64)
= 8
(2) For the points (-5,-2) and (1,-2):
d = sq.root of((1-(-5))^2 + (-2-(-2))^2)
= sq.root of (36 + 0)
= 6
(3) For the points (1,-2) and (-5,6):
d = sq.root of((-5-1)^2 + (6-(-2))^2)
= sq.root of(36 + 64)
= sq.root of(100)
= 10
Therefor the length of the longest side is 10 units
Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7
