Answer:
Question 1: False
Question 2: True
Question 3: True
Question 4: False
Step-by-step explanation:
Peter babysits his sister 2 days: Monday and Friday.
He babysits for his neighbor 40% of the time between Monday through Friday. This includes 5 days. 40% of 5days = 2 days.
On the weekend, Peter babysits 50% of the days. There are 2 days in the weekend
50% × 2 days = 1 day.
Question 1: False
Altogether, Peter babysits 5 days every week.
Question 2: True
Question 3: True
Peter babysits 4 out 5 days during Monday-Friday 4/5= 80%
Question 4: False
Peter babysits 5 days out of 7 during the week. 5/7 = 71% of the days, which is less than 90%
The decimal is non-terminating.
The decimal is non-repeating.
To be honest Im not sure what number 4 means...
Answer:

Step-by-step explanation:
<u><em>step(i):</em></u><em>-</em>
<em>Given the second term of a G.P is '4'</em>
<em>The general term of nth term is </em>
<em></em><em></em>
<em></em>
…(i)
<em>Also Given the fifth term of a G.P is '81'</em>
…(ii)
<u><em>Step(ii)</em></u>:-
<em>Dividing the equation (ii) divided by (i)</em>

Answer from: Quest
d, x=8
step-by-step explanation:
simplifying
4x + -5 = 2x + 11
reorder the terms:
-5 + 4x = 2x + 11
reorder the terms:
-5 + 4x = 11 + 2x
solving
-5 + 4x = 11 + 2x
solving for variable 'x'.
move all terms containing x to the left, all other terms to the right.
add '-2x' to each side of the equation.
-5 + 4x + -2x = 11 + 2x + -2x
combine like terms: 4x + -2x = 2x
-5 + 2x = 11 + 2x + -2x
combine like terms: 2x + -2x = 0
-5 + 2x = 11 + 0
-5 + 2x = 11
add '5' to each side of the equation.
-5 + 5 + 2x = 11 + 5
combine like terms: -5 + 5 = 0
0 + 2x = 11 + 5
2x = 11 + 5
combine like terms: 11 + 5 = 16
2x = 16
divide each side by '2'.
True because tan(20)=2.1 and cot(20)=is o.44
