A rational number is any number that can be represented as a fraction. (7=7/1 or 52 = 26/1 ).
An irrational number is a number like 3.14159 (pi) or anything like that.
Answer: -45
Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here, we have 7 + -12 which is -5.
When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.
Now, we have (-5) (9).
Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.
Therefore, (7 + 12) × 9 = -45.
4(2+3-1)=16
3(2+4)-1=17
3*1(2+4)=18
4(2+3)-1=19
4*1(2+3)=20
Answer:
3/8
Step-by-step explanation:
Three of the eight outcomes have exactly two heads: HHT, HTH, THH. The probability of getting exactly two heads is 3/8.
6% of $95 = $5.70
multiply $5.70 by 11 years = $62.70 <— interest gained over 11 years
multiply $18 by 11 years = $198 <— total added over 11 years
add $95 + $62.70 + $198 = $355.70
there will be a total of $355.70 in your account after 11 years
