Answer:

Mr. Vadar washed more than his son.

Step-by-step explanation:

First, you have to make these fractions have an equivalent denomoninator so you can compare them better.

2/7 is the same as 8/28 because you multiply the top and bottom by 4 due to the LCM being 28.

1/4 is the same as 7/28 which you get by multiplying the top and bottom by 7.

7/28 is bigger

Jamie, Lily, and Alice collectively weigh 192 pounds. Lily is 3 times as heavy as Jamie, and Alice is 11 pounds. Lighter than Li

lbvjy [14]

Answer:

Alice is 47 pounds havier than Jamie.

Step-by-step explanation:

Let be "j" the weight in pounds of Jamie, "l" the weight in pounds of Lily and "a" the weight in pounds of Alice.

Based on the data given in the exercise, we can know that:

$j+l+a=192$ [Equation 1]

$l=3j$ [Equation 2]

$a=l-11$ [Equation 3]

Solve "j" from the Equation 2:

$j=\frac{l}{3}$

Substitute this equatio and the Equation 3 into the Equation 1 and solve for "l":

$\frac{l}{3}+l+(l-11)=192\\\\\frac{7}{3}l=203\\\\l=(203)(\frac{3}{7})\\\\l=87$

Substitute the value of "l" into the equation $j=\frac{l}{3}$ to find "j":

$j=\frac{87}{3}=29$

Substitute the value of "l" into the Equation 3 to find "a":

$a=87-11=76$

Subtract the weight of Jamie from the weight of Alice in order to find how much heavier is Alice than Jamie:

$76lb-29lb=47lb$

Alice is 47 pounds havier than Jamie.

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best inte

stellarik [79]

Let

s--------> the length side of the cube

we know that

the volume of the cube is equal to

$V(s)= s^{3}$

if the length side s is equal to $2\ feet$

then

$s=2\ feet$

and the volume is equal to

$V(2)= 2^{3}$

$V(2)= 8\ feet^{3}$

therefore

<u>the answer is the option</u>

D. A cube with side lengths of 2 feet has a volume of 8 cubic feet.
