Answers

remember some basic rules
(x^m)/(x^n)=x^(m-n)
and
x^ (m)/(n)= \sqrt[n]{x^m}


so
(x^(1)/(2))/(x^(2)/(7))=x^{(1)/(2)-(2)/(7)}
1/2-2/7=
7/14-4/14=
3/14

x^{(1)/(2)-(2)/(7)}=x^{(3)/(14)}

x^ (3)/(14)= \sqrt[14]{x^3}

The sum of a number b and 3 is greater than 8 and less then 12

Answers

The sum of a number b and 3 is greater than 8 and less than12=> b + 3 < 8
=> b + 3 > 12

Now,let’s combine this into an expression:
=> 8 < b+3 < 12
=>  (8 - 3) < b < (12 - 3)
=> 5 < b < 9
Thus, the answer in the given situation is 9 because 9 is greater than 8 butless than 12.

Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50 a month to her savings. How much does Julia need to save each month in addition to her parents' contribution if she wants to have a $2700 down payment on a car at the end of the year? Define a variable and write an equation to represent this situation.

Answers

Answer:

12x+600=2700

$175

Step-by-step explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be 12x.

We can represent our given information as:

12x+600=2700\n12x=2700-600\n12x=2100\nx=(2100)/(12)\nx=175

Therefore, she needs to save $175 per month.

Form a sequence that has two arithmetic means between -1 and 59. a. -1, 29, 29, 59
b. -1, 19, 39, 59
c. 19, -1, 59, 39
d. -1, 14, 29, 44, 59

Please select the best answer from the choices provided


a) A
b) B
c) C
d) D

Answers

Answer:

Correct choice is B

Step-by-step explanation:

For the numbers -1 and 59, find the difference 59-(-1):

since 59-(-1)=60 and (60)/(3)=20 (two arithmetic means tells you there will be three intervals), two arithmetic means will be

  • -1+20=19;
  • 19+20=39.

The only correct sequence is -1, 19, 39, 59.

Answer:

b.

-1, 19, 39, 59
