1cm = 16km
1cm • x = 23.1cm
x = 23.1
16km • 23.1 = 369.6km
The real distance is 369.6km.
Not sure what the question is, but I'm guessing you want to find out the area of the rectangle.
The distance between points P and Q is 4.
The distance between points Q and R is 3.
So the area is 3 * 4 = 12.
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Answer:
440cm²
Step-by-step explanation:
*Area= (a+b)/2×h
(19+25)/2*20
= _ * 440cm². *_
(4^p*4^1)^3) =4^15
add the exponents
(4^(p+1))^3 = 4^15
multiply the exponents
(4^3(p+1))= 4^15
the exponents have to be the same
3(p+1) = 15
divide by 3
p+1 = 5
subtract 1
p =4
Eric is not correct
p=4
