Step-by-step explanation:
2L+2W= L*L+W*W= 2*2+2*2= 8
L= lenght
W= width
(the formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together)
w=2l-p÷2; w=p-1÷2; w=p-21÷2 w=p-2w÷21????
Answer:
$46.20
Step-by-step explanation:
His earnings: 8.8*7 = 61.6
He gave away 1/4, so he has 3/4 left
3/4*61.6=46.2
Answer:
7,228,202%
Step-by-step explanation:
Population at first census in 1979 was 3929
If the Population had increased to 284,000,000 by 2000, the population increase will be;
284,000,000-3929
= 283,996,071
%increase in population = increment/initial population×100%
= 283,996,071/3929×100%
= 7,228,202%
This means that the population has increased by 7,228,202%
Answer:
C
Step-by-step explanation:
Y - 4 = -2x + 10 Multiply -2 to the inside the brackets
Y = -2x + 14 Add the 4 over
First write both vectors in terms of their horizontal and vertical components.
G = (40.3 m)(cos(-35.0º) x + sin(-35.0º) y)
G = (33.0 x - 23.1 y) m
(where x and y are the unit vectors that point in the positive horizontal and vertical directions, respectively)
H = (63.3 m)(cos 270º x + sin 270º y)
H = (-63.3 y) m
Then the vector sum is
G + H = (33.0 x - 86.4 y) m
which has a magnitude of
|| G + H || = √[33.0^2 + (-86.4)^2] = 92.5 m
