Answer:
=1.99 sec
Step-by-step explanation:
t=k√d
k= constant
3=k√34.1
3=5.839k
k=0.5137
t=0.5137√15
t=1.99 sec
Answer:
n = 2.5 or n = (5/2)
Step-by-step explanation:
(2n+4) +6 = -9 + 4(2n+1)
first distribute the 4 to the (2n+1)
(2n+4) +6 = -9 + (8n+4)
then add 9 to both sides to cancel out the -9 on the right side
(2n+4) +15 = (8n+4)
next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract
15 = 6n
then divide 15 by 6 to get your final answer
n = 2.5
or
n = (5/2)
Answer:

Step-by-step explanation:
Answer:
c) 300.9 ft²
Step-by-step explanation:
He has 4 1/4 bags of mulch in his shed to use. Each bag of mulch will cover 70.8 ft².
Hence:
1 bag of mulch = 70.8ft²
4 1/4 bags of mulch = x ft²
Cross Multiply
1 bag × x ft² = 4 1/4 × 70.8
x ft² = 4 1/4 × 70.8/1
x = 300.9 ft²
Option c is correct.
