Yes, I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.

<h3>What is a right-angled triangle?</h3>

A right-angled triangle serves as the triangle having one of its angles equal to 90 degrees.

It should be noted that the other two angles sum up to 90 degrees., hence I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.

Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1030 was collected. First

Marrrta [24]

Answer:

170 tickets.

Step-by-step explanation:

Write formulas for the question.

$N_2+N_3=400$

$2N_2+3N_3=1030$

Then use substitution.

$N_2=-N_3+400$

$2(-N_3+400)+3N_3=1030$

$-2N_3+800+3N_3=1030$

$N_3=230$

So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

$N_2+230=400\\N_2=400-230\\N_2=170$

What percentage of tickets sold were to seniors?

Kay [80]

<u>Given</u>:

The number of tickets sold to children $=35+87+62=184.$

The number of tickets sold to adults $=56+177+205=438.$

The number of tickets sold to seniors $=32+14+54=100.$

To determine the percentage of tickets sold to seniors we need to determine the total number of tickets sold to each category.

<u>To determine the percentage of tickets sold to seniors:</u>

In order to determine the percentage of tickets sold to the seniors, we divide the tickets sold to seniors by the total number of tickets sold to children, adults, and seniors.

This value is multiplied with 100 to convert it into a percentage.

The number of tickets sold to seniors $=100.$

The total number of tickets sold to children, adults, and seniors $= 184+438+100=722.$

The percentage of tickets sold to seniors $= \frac{100}{722} (100) = 0.1385(100)=13.85\%.$

Rounding this off, we get the value as 13.9%

Hence, option 1 is the correct answer.
