Answer:
r =29.82
Step-by-step explanation:
r/7.1 = 4.2
Multiply each side by 7.1
r/7.1 *7.1 = 4.2*7.1
r =29.82
If the width is w then the length = 2w + 40, so the area
= w(2w + 40)
= 2w^2 + 40 w
So:
1000 meters = 1 kilometer,
So we can use the ratio 1km/1000m
Thus,
.007 kilometers*(1000m/1km) = 7 meters
So the equation is:
.007 kilometers = 7 meters
or
.007km = 7m
Answer:
x=199 and y=158
Step-by-step
Let x and y be two numbers
Given that the sum of the two numbers is 357, it may be written as
difference of the two numbers is 41, it may be written as
Now adding (1) and (2), we get
_______________________________________
_______________________________________
(Where y is in alternative signs so it may be cancelled)
Therefore
now substituting x=199 in (1) we get
Therefore
Answer:
6 millimeters.
Step-by-step explanation:
1 millimeter : 4 metres
x millimeters : 24 metres
x = (24÷4) × 1
x = 6 × 1
x = 6 millimeters
