Answer:
7.33333 hours
Step-by-step explanation:
Theo's speed = 55mph
Distance = speed * time
Distance covered after 2 hours
Distance = 55 * 2 = 110 miles (distance already covered by Theo when Dennis left
Dennis speed = 70mph
Let time taken to catch up = x
70x = 110 + 55x
70x - 55x = 110
15x = 110
x = 110 / 15
x = 7.33333 hours
Answer:
a. 1/27 b.3 1/2
Step-by-step explanation:
a.1/3*1/3*1/3=1/(3^3)=1/27
b.2 1/3*1 1/2*1= 3 1/2
If s=side, then each side is 12m.
It got cut off but
12mx12m=144m^2 because mxm=m^2.

Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:

It is provided that, Renee recognizes that 7 and
are reciprocals, so she would like to find their product before she multiplies by
.
The associative property of multiplication states that:

The commutative property of multiplication states that:

The distributive property of multiplication states that:

The identity property of multiplication states that:

So, Renee should use the commutative property of multiplication to find the product of 7 and
,

Thus, the correct option is commutative property.
