<h3>Answer: Similar - AA </h3>

Reason:

We're given these two angle congruences:

$\angle P \cong \angle S\\\\\angle Q \cong \angle T$

These are the blue and red angles marked in the diagram below. Since we have two pairs of congruent angles, we can use the AA similarity theorem to prove the triangles are similar.

Similar triangles have the same shape, but are likely different sizes. Triangles with the same shape indicates the corresponding angles are congruent.

The info that PR = 12 and SU = 3 isn't used or needed. Your teacher may have put that in there as a distraction or filler.

Do I need to put parentheses in this? Why it why not?

Oksana_A [137]

Answer:

Parentheses can change the result of the answer. If you want to add 4 and 0.95 first, then multiply that number by 3, then you need parentheses.

Step-by-step explanation:

When you are given the question 3 X 4 + 0.95, it has to types of operations. <u>People solve using the order PEDMAS</u>:

Parentheses,

Exponents,

Division and Multiplication,

Addition and Subtraction.

Since there are <u>no parentheses</u> or exponents, the solver will do multiplication first, then addition.

3 X 4 + 0.95 Multiply first

= 12 + 0.95 Now add

= 12.95 Answer without parentheses

If you add <u>parentheses around 4 + 0.95</u>, the answer would change. According to PEDMAS, the parentheses must be solved before anything else.

3 X (4 + 0.95) Add inside parentheses

= 3 X (4.95) Now multiply

= 14.85 Answer with parentheses

If you added <u>parentheses around 3 X 4</u>, the answer would not change, because you still multiply first.

(3 X 4) + 0.95 Solving parentheses first

= 12 + 0.95 Add

= 12.95 Answer same as original

Find the area of each figure. Round to the nearest hundredth where necessary.

leonid [27]

Answer:

A = 1,307 cm^2

Step-by-step explanation:

Formula of Surface Area of a Rectangle:

A = 2 (lw + lh + wh)

length*width = (20)(23) = 460

length*height = (23)(4.5) = 103.5

width*height = (20)(4.5) = 90

A = 2 (460 + 103.5 + 90)

A = 2(653.5)

A = 1,307 cm^2

A football stadium has 9,607 seats. At one game, people sat in 7,599 of the seats. How many seats were empty? What is the total

Mila [183]

9607-7599= 2008

So there are 9607 seats

7599 were full

Then that leaves 2008 seats empty
