The volume of a cube is 9000 m3. If the volume of the cube was measured in cm3, which would change?
serg [7]
There are 100 cm in 1 m
this is m^3
so (1m)^3 = (100cm)^3
1m^3 = 1000000 cm^3 or 10^6 cm^3

so if the volume of the cube was measured in cm^3
it would be 10^6 times larger
(9000 times 10^6)

A family of 2 adults and 3 children went out to dinner. The total bill was $42. Each child's dinner cost $4. How much did each a
Yanka [14]

Answer: Each adult’s meal costed $15

Step-by-step explanation:

This situation can be modeled by the following equation:

2a + 3c = 42, where a = the cost of an adult’s meal, and c = the cost of a child’s meal


Since we know from the problem that a child’s meal costs $4, we know c:

2a + 3(4) = 42


At this point, we can just solve the resulting equation for a:

2a + 3(4) = 42

= 2a + 12 = 42 (simplify 3(4))

= 2a = 30 (subtract 12 from both sides)

= a = 15 (divide both sides by 2)


So, the cost of each adult’s meal was $15.

Please help me thnk you

For this question, we use the Pythagorean theorem.

a^2+b^2=c^2

We know the lengths of the legs, a and b.
a=3
b=4

Now, let's solve for the hypotenuse, c.

3^2+4^2=c^2
25=c^2

Take the positive square root.

\boxed{c=5}

Hope this helps! :)
