To multiply a decimal number by 10,
o move the decimal point two places to the left.
move the decimal point two places to the right.
move the decimal point one place to the left.
move the decimal point one place to the right.

Move the Decimal point one place to the right.

Step-by-step explanation:

say you have 4.5×10, the Zero determines how many times you have to move the decimal. In this case you move it one time because there is only one zero. so your answer will be 45

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
