Tickets for a school football game cost 1.00 if purchased before the day of the game. They cost 1.50. They cost 1.50 each if bou

cluponka [151]

Answer:

Let x = number of gate tickets, ($1.50)

Since there were 600 tickets sold, let (600-x) = the $1 tickets

1.50 tickets + $1 tickets = $700

1.5x + 1(600 - x) = 700

1.5x - x = 700 - 600

.5x = 100

x = 100/.5

x = 200 ea 1.50 tickets sold at the gate

;

Check: there were 600 - 200 = 400 ea $1 tickets sold

1.50(200) + 1(400) = $700

Find the solution set for this equation:<br> -a2+4a=0<br> (Separate the two values with a comma)

Rashid [163]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: \{ 0,4 \}$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: - {a}^{2} + 4a = 0$

$\qquad \tt \rightarrow \: - ( {a}^{2} - 4a) = 0$

$\qquad \tt \rightarrow \: {a}^{2} - 4a = 0$

$\qquad \tt \rightarrow \:a(a - 4) = 0$

The two cases are :

a = 0

a -4 = 0, that leads to a = 4

We can conclude :

$\qquad \tt \rightarrow \:solution \: (a) = \{ 0,4\}$

Use the diagram of the right triangle above and round your answer to the nearest hundredth.

Yakvenalex [24]

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

Help me solve this and please explain to me. :(:

aalyn [17]

Answer:

E = 50

D = 150

Step-by-step explanation:

We know that the exterior angle is equal to the sum of the opposite interior angles

D + E = 200

D = 3E

Substituting that into the equation

3E + E = 200

Combing terms

4E = 200

Divide by 4

4E /4 = 200/4

E = 50

D = 3E

D = 3*50 = 150
