12÷5=2.4
2.4 minutes per watch together
so it takes john about 0.4 seconds to assemble a watch alone
Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
Use your fingers.
Hold down the first finger on your left hand, nine fingers remain up. The answer is 9
For two hold down the second finger on your left hand. On the left is one finger standing, and on the right are 8 fingers standing. The answer is 18
This pattern works for everything up to ten. Then you remember 9 x 11 is 99. And 9 x 12 is 108
3 out of 6 because there are 6 numbers altoghether on a ordinary die and there are 3 odd numbers on that die 1,3, and 5 therefore the answer is 3/6
Answer:
x=2.6
Step-by-step explanation:
We can use the Pythagorean theorem to find the third side
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + x^2 = 4^2 where x is the unknown side
9 + x^2 = 16
Subtract 9 from each side
x^2 = 16-9
x^2 = 7
Take the square root of each side
sqrt(x^2) = sqrt(7)
x =2.645751311
Rounding to the nearest tenth
x = 2.6
