Answer:
Perimeter = 3.14 km^2
Step-by-step explanation:
Diameter = 2 , R = 1
Perimeter of semicircle = piR
= 3.14*1
= 3.14 km^2

Write the total number of seeds in scientific notation
Given:
Number of pots = 22,000
Number of seeds = 15
<em>Total number of seeds = Number of pots × Number of seeds</em>
= 22,000 × 15
= 330,000
Scientific notation is written in multiples of 10
- Count the number of digits
- Insert a decimal point between the first digit and other digits
- count the number of digits after the first digits
- multiply by 10 raise to the power of number of remaining digits after first digits
= 3.30000 × 10^5
Therefore,
the total number of seeds in
scientific notation is 3.30000 × 10^5

Answer:
S = 935 when t ≤ 7
S = (180t - 325) when t > 7
Step-by-step explanation:
John's weekly salary = $375 + commission on number of cars he sell
Commission for the first seven cars sold = $80 per car
Commission above 7 cars = $180 per car
If John sells t cars each week then commission earned by John
= 80×7 + 180(t - 7)
So the salary for week = 375 + commission
S = 375 + 560 + 180(t - 7)
S = 935 + 180(t - 7)
S = 935 when t ≤ 7
(180t - 325) when t > 7
Answer:
48128m^3
Step-by-step explanation:
Given data
For the building
L=64m
W= 6m
H= 36m
The volume is
V= LWH/3
V=64*64*36/3
V=147456/3
V=49152m^3
For the off-Cut
L=16m
W= 16m
H= 12m
The volume is
V= LWH/3
V=16*16*12/3
V=3072/3
V=1024m^3
Hence the volume of the truncated part/Building
= Volume of building-volume of off-cut
=49152-1024
=48128m^3
