Answer:
8 weeks
Step-by-step explanation:
First we have jas starting with 145 dollars.
her adds 36 a week to savings.
The total savings we need to get to is 433 dollars.
Let w = weeks needed to get to goal
145 + 36w = 433
Subtract 145 from both sides:
36w = 433 - 145
Simplify:
36w = 288
Divide both sides by 36:
w = 288/36
w = 8
After 8 weeks, jas will have saved 433 dollars.
Check for truth:
145 + 36(8) = 433
145 + 288 = 433
433 = 433 ; check
1) the types of number are the negative integers (e.g √-1 √-3 <span>√-5 are not defined)
2) the answer is No, proof: 2x</span>√-1 is not defined because <span>√-1 doesn't exist
3) the answer is No, proof: </span>√-1 - 3 is not defined because √-1 doesn't exist
4) the answer is Yes, proof: (√-1 )²= -1 this is a real number
5) the answer is No, proof: (√-1 )^3= (√-1 )²(√-1 )= - 1(√-1 ), and - 1(√-1 ) is not defined because √-1 doesn't exist
6) the result would be defined with the following cases:
√-1+n, n>1
√-1xn, n<0
√-1/n, n<0
7) the result would not be defined with the following cases:
√-1+n, n<0
√-1xn, n>0
√-1/n, n>0
8) to square <span>3 + √-1, I use the method of complex number
i²= -1, it implies i= </span>√-1
so 3+√-1=3+i, and then (3+√-1)²=(3+i)²= 9 -1+6i= 8-i= 8-√-1
9) it is used for finding complex roots of a number
Answer:
1/3
Step-by-step explanation:
Answer: D.23 x 305 = n, n = 7015
Step-by-step explanation:
23 x 305 = 7015
7015 square feet
D because 3/4 is .75 so 7.75 divided by .75 equals 10.333333333333333
