Answer:
970 cm
Step-by-step explanation:
Given that:
Size of brick :
25cm × 16cm × 10cm
Number of bricks = 4700
Dimension of wall = 20 m long × 20 cm wide
Let the height = h
Hence, dimension of wall (length and height)
2000 cm × h
Dimension of window = 2m × 1.5m = 200cm × 150cm
Number of windows = 2
Total area covered by windows = 2 * (L * B)
= 2(200 * 150) = 60,000cm
Brick = (25 * 16) * 4700 = 1, 880, 000 cm ( length and height)
Wall = 2000 * height - 60,000 = 1880000
2000height - 60,000 = 1880000
2000height = 1880000 + 60,000
2000height = 1940000
Height = 1940000 / 2000
Height of wall = 970 cm
Answer:
0.06
Step-by-step explanation:
ok 1 tenth and 1 sixth are our equasions so lets conver then to desimals and lets start with 1 tenth so we devide 1/10 is 0.1 and now for 1 sixth is 0.6 so now we multiply the two and get 0.06
Answer:
Nobody on this website XD
product is multiplication
2 negative numbers multiplied by each other equal 2
since it is multiplication the numbers would need to be 2 or less
therefore the 2 numbers are -1 and -2
-1 * -2 = 2
Answer:
2) -3x+10
4) -4x+10+x
Step-by-step explanation:
Use the distributive property to get rid of the parentheses.
(2 × -2x) + (2 × 5) + x
-4x + 10 +x is correct, but the x's can be combined.
(-4x + x) + 10 = -3x + 10
