Answer:
160in²
Step-by-step explanation:
40% = 0.4 = 4/10
The length is 20, 40% of that is (0.4)(20) = 8in
Length * width . = 20*8 = 160in²
3.25 meters = 325 cm
325cm / 5 cm= 65 name tags with the ribbon she has.
She still needs 35 name tags, so 35 × 5 = 175cm cm.
She still needs 175cm of ribbon to make a total of 100 name tags.
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = 
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
Just combine these.
3x + 3x = 6x
x = 6
y = 1
