Answer:
the number of the given percentage is 200, option D
Step-by-step explanation:
given:
If 32% of a number is 64,
find:
what is the number?
let N is the number
0.32 x N = 64
N = 64 / 0.32
N = 200
therefore,
the number of the given percentage is 200, option D
Length(l)= 2w+6
Width(w)= w
Area(A)= 140 m²
Area= l*w
140 = l*w
140= (2w+6)w
140= 2w²+6w( divide each side by 2)
70= w²+3w
w²+3w -70= 0
(^^^^^^Factor out expression)
(w-7)(w+10)= 0 (set each expression equal to zero and use the positive answer as the value for "w"(because a negative width is impossible))
w-7=0
w=7m
w+10=0
w= -10m (Impossible for a physical measurement to negative: therefore This "w" value is incorrect)
Use w=7 to find "l"
l= 2w+6
l=2(7)+6
l=14+6
l=20 m
Answer:
The dimensions of a rectangle are length and by width. For this rectangle the dimensions are 20 meters by 7 meters.
(width= 7 meters)
(length= 20 meters)
Answer:
The correct option is;
The ratio of the area of the scale drawing to the area of the sign is equal to the square of the scale factor
Step-by-step explanation:
Here we have a scale factor of 1:8
Therefore area of drawing = 1/2×base, b×height, h = 1/2×b×h
Hence, the area of the triangular sin will be given by 1/2×8×b×8×h
Area of triangular sign = 64 × 1/2×b×h
Hence the ratio of the area of the scale drawing to the area of the triangular sign is equal to the square of the scale factor.
