Answer:
The total volume = 160.29
Step-by-step explanation:
Kindly refer the attatchment.
Every time that she stopped, the value of the speed is 0, the speed limit is the maximum represented in the graph and when she travels at this speed for a while the graph is a horizontal line.
So she starts at 0, then increases her speed until a limit then she drives at this speed for a while which is represented by a horizontal line. then, she has to slow to a stop, which means she goes back to 0, later increases her speed until the limit, drives a while until she finds a stop sign, represented by a horizontal line, and then goes to 0.
In conclusion, the graph that represents the journy is the fourth graph.
Answer:
length=22
width=21
Step-by-step explanation:
let, length be x and width be y.
x=2y-20
2(x+y)=86
or, 2(2y-20+y)=86
or, 2(3y-20)=86
or, 6y-40=86
or, 6y= 126
or, y= 126/6
y= 21
x= 2×21-20 = 42-20 =22
Answer:
I believe the answer is A.
Step-by-step explanation:
If there are 13 daises per bouquet, that means one bouquet is all daises. The other bouquet has 30 flowers. 30-13 is 17 which means there are 17 other flowers rather than daises. 17 is greater than 13 by 4 which is not that much. Therefore I think the answer is letter A.
Answer:
-41
Step-by-step explanation:
arithmetic sequence formula:
where an = nth term , a1 = first term, n = # of terms and d = common difference
we want to find the 21st terms
The first term is -1 so a1 = -1
The number of terms is 21 so n = 21
and the common difference appears to be -2 because as the sequence goes on the number previous to it is subtracted by 2. eg. to get to -3 from -1 we subtract 2 ( -1 - 2 = -3) so d = -2
to find the 21st term we plug in the values of the variables
an = a1 + (n-1)d
a1 = -1 , n = 21 and d = -2
an = -1 + (21-1)(-2)
subtract 1 from 21
an = -1 + (20)(-2)
multiply -2 and 20
an = -1 + -40
add -1 and -40
an = -41
the 21st term would be -41
