Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592
Step-by-step explanation:
given that 1.5 gram of fat =3% of 2000 calorie diet.
Thus, 1.5 gram of fat contributes to 3/100*2000= 60 calorie of diet.
Generally 6% of the diet must be fat.(recommended)
Since, 1.5 gram = 3%
thus, 3 gram =6%.
320 girls x 0.2 lh probability = 64 lhg
250 boys x 0.1 lh probability = 25 lhb
Total is the sum of the two 64+25 = 89
I'd say that the relationship between y and x is that they're both equivalent to each other, since -3 = -3.
