(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
So, we need to divide the reward into 5 parts, then award 2 parts to Jaden and 3 parts to Cadence.
$140 / 5 = $28
Jaden gets 2 * 28 = $56
Cadence gets 3 * 28 = $84
$56 + $84 = $140
Answer:
height = 14.2 m , base = 7.1 m
Step-by-step explanation:
let the base be b then height h = 2b
The area (A) of a triangle is calculated as
A =
bh
Here A = 50 , then
× b × 2b = 50
b² = 50 ( take square root of both sides )
b =
≈ 7.1 ( to the nearest tenth )
Then base = 7.1 m and height = 2 × 7.1 = 14.2 m
