Answer:
No
Step-by-step explanation:
25% as a decimal is 0.25
and 0.3 as a percentage is 30%
The product is 28. 11-7= 4. 4×7=28
Answer:
A and B
Step-by-step explanation:
In A the color of the student's eyes doesn't determine the gender of the person so event B doesn't depend on A
In B it is also the same thing. Liking iced tea doesn't mean you automatically sing in a choir
In C event A depends on even B. Practicing free throws can help you in joining a team which makes B dependent on group A
Finally, In D event A is dependent on B. Doing homework can most likely help you pass a test
Answer:
9
Step-by-step explanation:
9*5=45
45-2=
43
<h3>Answer to Question 1:</h3>
AB= 24cm
BC = 7cm
<B = 90°
AC = ?
<h3>Using Pythagoras theorem :-</h3>
AC^2 = AB^2 + BC ^ 2
AC^2 = 24^2 + 7^2
AC^2 = 576 + 49
AC^2 = √625
AC = 25
<h3>Answer to Question 2 :-</h3>
sin A = 3/4
CosA = ?
TanA = ?
<h3>SinA = Opp. side/Hypotenuse</h3><h3> = 3/4</h3>
(Construct a triangle right angled at B with one side BC of 3cm and hypotenuse AC of 4cm.)
<h3>Using Pythagoras theorem :-</h3>
AC^2 = AB^2 + BC ^ 2
4² = AB² + 3²
16 = AB + 9
AB = √7cm
<h3>CosA = Adjacent side/Hypotenuse</h3>
= AB/AC
= √7/4
<h3>TanA= Opp. side/Adjacent side</h3>
=BC/AB
= 3/√7
