Which calculator correctly shows the quotient of 6.47x10^-15/3.36x10^-29
Alex73 [517]
<h2>Answer:</h2>

\boxed{1.92559524e+14}

<h2>Step-by-step explanation:</h2>

Scientific notation is a special way we choose for writing numbers. So the numers 6.47\times 10^{-15} \ and \ 3.36\times 10^{-29} are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:

\frac{6.47}{3.36}\times 10^{[-15-(-29)]}=1.92559524\times 10^{(-15+29)} \\ \\ \therefore 1.92559524\times 10^{14} \ or \ \boxed{1.92559524e+14}

The division has been performed using the rules for operation with exponentiation.

Answer:

Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

explain how you can tell whether a group of ratios represents a proportional relationship. PLEASE HELP
zubka84 [21]
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

hope this helps :)
