No because 4 laps around the track is one mile so if he did then he would have only done two and a half miles
Answer:
357.14 meter/min and 5.95 meter/sec
Step-by-step explanation:
A) his speed in metres/min=10000/28=357.14 meter/min
B) his speed in metres/second=10000/(28*60)=5.95 meter/sec
9 × (5 × 2) = (9 × 5) × 2
You can see that all the numbers are there and in the same order. The only thing that changed is the parentheses location.
This is called the Associative Property (of Multiplication, because you're multiplying).
Answer: Choice A) x = 15; y = 17
---------------------
Explanation:
The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15
We technically have enough to stop here, but let's keep going to find y
The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees
So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17
