The slope m is found from the following formula:
The correct choice is -14.
Answer:
Step-by-step explanation:
The given expression is
We have to find the value of given expression when -x=-4/5 and y= 1/3.
Substitute -x=-4/5 and y= 1/3 in the above expression, to find the value of given expression when -x=-4/5 and y= 1/3.
After multiplication we get
Taking LCM, we get
Therefore, the value of given expression is .
Answer:
Total = 686000 meters for 10 weeks 7 days a week.
Step-by-step explanation:
Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7
a = 8000
n = 10
d = 400
Sum = (a + L)*n/2
- L = a + (n - 1)*d
- L = 8000 + (10 - 1)*400
- L = 8000 + 9*400
- L = 8000 + 3600
- L = 11600 meters
Sum = (8000 + 11600)*10/2
Sum = 19600 * 10/2
Sum = 98000 meters.
This total represents 1 training day a week.
The total amount is 7 times this figure.
Total = 7 * 98000 = 686 000 meters.
A handy conversion to remember is that 60 mph equals 88 feet per second.
Therefore, 50 mph will be (5/6) of 88 feet per second or 73.3333333333 feet per second.
Answer:
14.14 units^2
Step-by-step explanation:
Find area of left rectangle (LR):
LR=2*3=6 units
Find area of right rectangle (RR):
RR=5*1=5 units
Find area of quadrant:
Q=1/4*pi*r^2
Q=1/4*pi*2^2
Q=1/4*pi*4
Q=3.14
So we add 3.14+6+5 to get around 14.14 units^2
