Answer:
20 Minutes
Step-by-step explanation:
First find out how many he eats per minute. 17/5 = 3.4
Then multiply 3.4 by all the answers until you get the right answer.
The main numbers and ratios or rates depending on the problem
The answer is B
volume of rectangular prism = (area* height )
so 2 * 4 * 9 = 72 cm3
9* 4 * 2 = 72 cm3
but they have differant surface area
The answer is {B} 728x2y3.
Let Daniel's age be 'x' years , hence, Lisa's age is (x - 5) years. Let Grandma's age be 'y' = 54 years.
Hence,
x(x - 5) = 2/3 × y
x² - 5x = 2 × 54 years / 3
x² - 5x = 36 years
x² - 5x - 36 = 0
∆ = (-5)² - 4(1)(-36) = 25 + 144 = 169
√∆ = √169 = 13

x1 = (5+13)/2, x2 = (5-13)/2
x1 = 9, x2 = -4
Since, age can't be negative,
Daniel's age = x = 9 years.
