Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

\tan(a)   = \tan(30)  =  \frac{1}{ \sqrt{3} }

and we know,

=》

\tan(a)  =  \frac{a}{b}

so, by above values of tan ( a ) we get,

=》

\frac{a}{b}  =  \frac{1}{ \sqrt{3} }

=》

\frac{a}{12}  =  \frac{1}{ \sqrt{3} }

=》

a = \frac{12}{ \sqrt{3} }

=》

a = 4 \sqrt{3}

=

=》

a = 6.93

hence, a = 6.93 m

2/5=w-3/2 w=19/10<br> What are the steps?
Mekhanik [1.2K]
2/5=w-3/2
remember that to solve we want to isolate 1 w one side by itself
also remember that we can do anything to an equation as long as we do it to both sides (except divide by zero)

2/5=w-3/2
so we add 3/2 to both sides to get rid of the 3/2
2/5+3/2=w+3/2-3/2
2/5+3/2=w+0
2/5+3/2=w

make the bottom numbers the same
the number is 10
2/5 times 2/2=4/10
3/2 times 5/5=15/10

4/10+15/10=w
4/10+15/10=(4+15)/10=(19)/10
w=19/10
so the steps are:
1. add 3/2 to both sides
2. make the denomenators of 2/5 and 3/2 the same so we can add them

Which of the following situations involve a permutation?
alina1380 [7]

Answer:

A, B, E

Step-by-step explanation:

Permutations are involved when order matters, as in lane assignment, passwords, and seating charts.

When the end result is a "group of 10 students", "3 employees", or "4 cashiers", clearly order does not matter. One student, employee, or cashier is as good as another in these cases.

Kim surveyed the students at her school to find out if they like hotdogs and/or burgers. The table below shows the results of th
Nimfa-mama [501]

Answer:

like burgers with the wrong total of 76/150 is 50.7%

do not like burgers with also the wrong total of 74/150 is 50% simplified

now with the right totals its 54% for liking burgers and 46% for not liking

Step-by-step explanation: 32 + 49 + 81 = 162

                                           44 + 25 + 69 = 138

right total (162) wrong total (76)

right total (138) wrong total (74)

right (300) wrong (150)

unless u simplified by 2 which is 150/300 then its right simplified

so im confused but this is my answer
