Step-by-step explanation:
Using two unit multiplier 628 km is equal to 62800000 cm
<u>Solution:</u>
628 kilometer to centimeter
We will go from kilometers to meters to centimeters.
Start by putting 628 km over 1:

We want to get rid of km and bring in m.
We know that 1000 m = 1 km.
Since km is in the numerator, we will make the first unit multiplier by putting 1 km in the denominator and 1000 m in the numerator, so the km will cancel. So we multiply by the unit multiplier,

Now the km's will cancel:

Now we want to get rid of m and bring in cm.
We know that 100 cm = 1 m.
Since meter is in the numerator, we will make the first unit multiplier by putting 1 meter in the denominator and 100 cm in the numerator, so the meter's will cancel. So we multiply by the unit multiplier


We cancel the m's and we end up with:

= 62800000 cm
Thus 628 km is equal to 62800000 cm
C. 1/5
because you multiple it times 5 every time
Answer:
Step-by-step explanation:
It is given that an isosceles triangle has two sides of length a and base b, then the perimeter of an isosceles triangle= Sum of all the sides
⇒a+a+b=15.7
⇒2a+b=15.7
⇒b=15.7-2a
Also, we know that he sum of the lengths of any two sides of a triangle must be greater than the length of the third side that means,
⇒a+a>b
⇒2a>b
Now, substituting the value of b in the above equation, we get
2a>15.7-2a
⇒4a>15.7
⇒a>3.925
Now, b=15.7-2a, therefore b=15.7-2(3.925)=15.7-7.85=7.85
Thus possible value of b is 7.85.
