Answer:
see below
Step-by-step explanation:
3^-7 x 3^7 = 1
The negative exponents put it in the denominator
1/ 3*3*3*3*3*3*3 * (3*3*3*3*3*3*3) = 1
The 3's cancel leaving
1/1 = 1
1=1
1 mile = 1760 yards
20 * 1.151 = 23.02
23.02 * 1760 = 40,515.2
40,515.2 / 60 = 675.243~
675.243~ / 60 = 11.2542~
They are traveling 11.25 yards per second
I took the number of knots multiplied by the approximate miles per hour equal
Then multiplied that by the number of yards in a mile, and then divided that by the number of minutes in an hour, and divided that by the number of seconds in a minute. That is how I got the answer, I hope it helps!
Answer:
x=y
Step-by-step explanation:
Answer: The equation for the line of reflection will be x = y.
Because it's a multiplication, we can choose this:
72=8x9
Answer:
490kpa
Step-by-step explanation:
V1 = 70ml and P1 = ? kpa
V2 = 15ml and P2 = 105kpa
if 15ml will give me 105kpa
then how many times is 70ml greater than 15ml
70/15 = 4.6667
then multiply it by 105kpa
4.6667 * 105 = 490kpa
meaning that if 15ml will give me 105kpa
then 70ml which is (15*4.667) will give 490kpa
