Answer:
#4=10.5
#5=48
Step-by-step explanation:
The formula for the triangle for area is 1/2 time base times hight
The forumale fot the triangle for volume is 1/2 time base times hight
So for number #4 it will be 1/2 x 3 x 7
and number #5, it will be 1/2 x 8 x 12
2pirad=360 deg
so
xrad/2pi=ydeg/360
times both sides by 360 to solve for ydeg
180xrad/pi=ydeg
so
7/9pi rad
180(7/9pi)/pi=ydeg
140=ydeg
140 deg
A is answer
1 metric ton is 1000 kilograms
2 metric tons is 2000 kg.
60 kilograms + 70 kilograms = 130 kilograms
2000 kg. + 130 kg. = 2130 kg.
The truck weighs 2130 kilograms.
