First one is 114
second one is 215.2
let me know if this doesn’t work :)
Answer:
Step-by-step explanation:
density = mass / volume
We already know the mass - 180g
Find the volume
Plug in the volume and mass in the density formula
Simplify
Answer:
105
Step-by-step explanation:
35 is 25% of the students in the school so you could do 35 x 4 which is 140...
then you will take 35 and subtract them...
140 - 35 = 105
So 105 is 75%
Answer:
The coordinates of point P are (-2, 1)
Step-by-step explanation:
The coordinates of the partition point (x, y) of a line segment whose endpoints are (x1, y1) and (x2, y2) at ratio m: n are
- x =
- y =
∵ P partitions segment GH in a ratio 1: 2
∴ P = (x, y)
∴ m = 1 and n = 2
∵ G = (-5, 5) and H = (4, -7)
∴ x1 = -5 and x2 = 4
∴ y1 = 5 and y2 = -7
→ Substitute them in the rule above to find x and y
∵ x = = =
∴ x = -2
∵ y = = =
∴ y = 1
∴ The coordinates of point P are (-2, 1)
