Answer:
Negative
Step-by-step explanation:
When you multiply a negative number by a positive number then the product is always negative.
<h3>
Answer: 14 km per hour</h3>
=====================================================
Work Shown:
x = rowing speed when there is no current
c = speed of the current
speeds are in km per hour
-----------
Going downstream, i.e. with the current:
x+c = faster speed since the current is pushing you
distance = rate*time
d = r*t
40 = (x+c)*2
x+c = 40/2
x+c = 20
c = 20-x
-----------
Going upstream, i.e. against the current:
x-c = slower speed since the current is working against you
d = r*t
16 = (x-c)*2
16 = 2x-2c
2x-2c = 16
2(x-c) = 16
x-c = 16/2
x-c = 8
x-(20-x) = 8 ... plug in c = 20-x
x-20+x = 8
2x-20 = 8
2x = 8+20
2x = 28
x = 28/2
x = 14 km per hour is the rowing speed when there is no current
Side note: the speed of the current is c = 20-x = 20-14 = 6 km per hour.
Step-by-step explanation:
26/7 ×35/ 8 =910/56
=16 1 /4
61/9 × 23 /4 =1403 / 36
=38 35/36
Answer:
To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.
HOPE THIS HELPED!!!!!!!!!!!!!XDDDDDD
