Answer:
45 percent
Step-by-step explanation:
20-11=9
9 divided by 20= 0.45
0.45 x 100= 45%
5/ 1+1= 5/2
1+4/1^2-3(1)-4= 5/-6
5/2 - 5/-6 does not equal zero
Please write that as 4.321 × 10^(−4). The " ^ " indicates exponentiation and the parentheses help make clear that your exponent here is a negative one.
Rewrite 4.321 × 10^(−4) by moving the decimal point 4 places to the left:
0.0004321
Step-by-step explanation:
24÷(45÷25)= 21
x=21
Hope this helped!
