Step-by-step explanation:
Answer: His answer is wrong
Explanation:
5(1/5^3) = 5(1^3/5^3) = 5(1/125)
5(5^3) = 5(125)
Let’s compare:
5(1/125) < 5(125)
Because 1/125 is smaller 125
Thus, it is not equal.
1)
a) 3/9= 0.333333333333 but you can just say 0.3
b) 4/3= 1.333333333333 but you also can say 1.33 or just 1.3
2)
a) 21/8, 21 over 8 if you solve you would get 2.625
b) 7(divide sign)4, which is also 7/4, if you solve you would get 1.75
c) 4/9 , 4 over 9 if you solve you would get 0.444444444 which is 0.4
d) 9/7, 9 over 7, if you solve it would be 1.285 which is 1.3
Answer:
36
Step-by-step explanation:
Total students un the contest = 84
<u>Number of students who gave their speech yesterday:- </u>

so 21 students gave their speech yesterday
- remaining students = 84 - 21
= 63
<u>Number of students who gave their speech today:-</u>

<u>Number of students who have given their speech</u>:-
= 21 + 27
= 48
<u>Number of students who still haven't given their speech :-</u>
= total - 48
= 84 - 48
<u>= 36</u>
Tangent 45 = height / 3
height = 3 * tan (45)
height = 3 * 1
height = 3
<span>Trapezoid area = ((sum of the bases) ÷ 2) • height
</span>
<span>Trapezoid area = (9 + 15) /2 * height
</span><span>Trapezoid area = 12 * 3
</span><span>Trapezoid area = 36
