2. Marlan explains to her friend why 497 is a rational number. which statement could she have used? A 4 +0.97 = 4.97 B 4.97 is a repeating decimal C 4.97 is a terminating decimal. D 4.97 cannot be represented as the quotient of two integers ​

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
