Area of a Triangle = 0.5 x Base x Height
Therefore the area of one mosaic triangle = 0.5 x 3 x 5 = 7.5
So the area of the whole mosaic is : 7.5 x 200 = 1500cm^2
Answer:
A
m less than or equal to 19
She can buy at most 19
Step-by-step explanation:
25 divided by 1.29 is 19.379844... but you can't buy fractions of a music song.
So the closest to the maximum would be 19.
(4*4*10)*3
160*3=480
(5*3*10)*2
150*2=300
480+300=780 cub. meters
The width is half the length, so is
width = (1/2)*length
width = (1/2)*(<span>3.2a + 0.18b) cm
width = (1.6a +0.09b) cm
The perimeter of the rectangle is twice the sum of length and width.
perimeter = 2*(length + width)
perimeter = 2*((3.2a +0.18b) cm + (1.6a +0.09b) cm)
perimeter = 2*(4.8a +0.27b) cm)
perimeter = (9.6a +0.54b) cm
