Answer:
C.34
Step-by-step explanation:
you find the length which is 10 squares and the width which is 7 squares. Since the shape is a quadrilateral you add all sides to find the perimeter= 2L+2W. 2(10)+2(7)=20+14=34
Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Answer:
A. (3 , 1)
Step-by-step explanation:
Note the placement of x and y for points:
(x , y)
Plug in the corresponding numbers for the corresponding variables:
(x , y) = (3 , 1)
y = x - 2
(1) = (3) - 2
1 = 3 - 2
1 = 1 (True).
A. (3 , 1) is your answer.
