More = Addition
"Twice a Number" = Multiplication (specifically by two)
Since the order of operations tell us to multiply before we add, we can simplify
.
Multiply the 3 by 16 and the 16 by 3 to even the numbers to 48.
then multiply the 2 above by 16 and the 3 above by 3 so it becomes like this
Answer:
the answer
the ratio x:y is 25:18
Step-by-step explanation:
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
Answer:
500 metres
Step-by-step explanation:
As per the question statement:
Randy walks all the way around the block and stops when he gets back to where he started.
Distance of 1 unit is 10m.
Please refer to the image attached:
Let us assume that he starts from point <em>A</em> and then moves towards point <em>B</em>, then towards point <em>C </em>and then <em>D </em>and finally reaches point <em>A </em>back.
While walking from A to B, he walks parallel to x-axis for 9 - (-5) units i.e. 14 units.
While walking from B to C, he walks parallel to y-axis for 9 - (-2) units i.e. 11 units.
Similarly, C to D, he walks parallel to x-axis for 9 - (-5) units i.e. 14 units.
Similarly, D to A, he walks parallel to y-axis for 9 - (-2) units i.e. 11 units.
Total distance traveled is 110 + 140 + 110 + 140 = <em>500 metres.</em>
