Answer:
(2*7)*6 or 2*(7*6) = $84
Step-by-step explanation:
The associative property would always give the same value as an answer no matter the way of expression, once the expressions are right. So in this case,
Since has saves $2 every day and there are 7 days in a week,
2*7
and save this continously for 6 weeks.
(2*7)*6
This equals $84
OR
7 days in a week for 6 weeks
7*6
and saved $2 per day
2*(7*6)
This equals $84
The first answer we see is true the other is based on personal experience
<u>Given:</u>
The radius of the circle XY is XY = 11.4 in
The length of ZY is 15.2 in
The length of XZ is 19.6 in
We need to determine whether YZ is a tangent to the circle X.
<u>Is YZ tangent to the circle X:</u>
We shall determine whether YZ is a tangent to the circle X by using the Pythagorean theorem.
Thus, we have;
Substituting the values, we have;
Simplifying, we get;
Since, both sides of the equation are not equal, thus, YZ is not a tangent to the circle X.
Answer:
3 • (2x + 3) • (x + 1)
Step-by-step explanation:
Answer:
the newer moat is 169 cm longer than the older one
Step-by-step explanation:
in order to find the difference in length of the two castles, we will first find the perimeters of the two castles then calculate the difference in the perimeters:
old castle:
dimension = 484cm by 386cm
perimeter = 484 + 386 = 870 cm
new castle:
dimension = 725cm by 314cm
perimeter = 725 + 314 = 1039 cm
difference = 1039 - 870 = 169 cm
The total length of the moats used is equals to the perimeter of the sand castles, therefore, the newer moat is 169 cm longer than the older one.
