0.4 is the divisor, or whichever number is under the fraction. This is because the denominator of any fraction is always the divisor of the numerator of the fraction.
1/4 # hamburger = 16 oz to a pound so 1/4 is 4 oz.
1 doz baseballs (12), 5 oz each
Box = 9 oz.
Total weight = 12x5 = 60 oz. + 9 oz. = 69 oz.
69/16 = 4 lb. 5 oz.
Answer:
i think c
Step-by-step explanation:
A ) Length = 5 - 2 x
Width = 3 - 2 x
The area of the bottom:
A = L x W = ( 5 - 2 x ) ( 3 - 2 x ) = 15 - 10 x - 6 x + 4 x² =
= 4 x² - 16 x + 15
b ) 4 x² - 16 x + 15 = 10
4 x² - 16 x + 5 = 0
x = (16 - √(256 - 80))/ 8 = ( 16 - 13.266 ) / 2
x = 0.34 in
