PLEASE!IT'S URGENT!!! Richard wants to install a paver patio in the shape shown. The dotted line represents a line of symmetry.
stira [4]

Answer:

The correct option is B. 290 square yards  

Step-by-step explanation:

To find the required area of the figure :

Divide it into two parts , one is triangle and the other is rectangle

Finding the area of triangle :

Base of triangle = 20 yards , Height of the triangle = 20 - 9 = 11 yards

So, Area of the rectangle = 0.5 × Base × Height

⇒ Area of the rectangle = 0.5 × 20 × 11

                                        = 110 square yards

Finding the area of rectangle :

Length of rectangle = 20 yards

Width of rectangle = 9 yards

So, Area of the rectangle = Length × Width

⇒ Area of the rectangle = 20 × 9

                                        = 180 square yards

Therefore, Area needed to be paved to cover the initial patio = Area of rectangle + Area of the triangle

⇒ Area needed to be paved to cover the initial patio = 110 + 180

                                                                                         = 290 square yards

Hence, The correct option is B. 290 square yards

Rudy invested $2460 in a money market account for 3 and 1/2 years. He earned $452 in simple interest. Which best represents the
antiseptic1488 [7]

Answer:

B. 5 and 1/4 percent

Step-by-step explanation:

Step one:

given

principal= $2460

time= 3 and 1/2 years= 3.5 years

SI= $452

Required

The rate

Step two:

we know that

SI= PRT/100

substituting our data we have

452= 2460*R*3.5/100

452=8610R/100

cross multiply

452*100= 8610R

divide both sides by 8610

45200/8610= R

R= 5.25%

R= 5 and 1/4 percent

Sladkaya [172]

A square rotated about its center by 360º maps onto itself at 90°, 180°, 270° and 360° - 4 different angles of rotation.

You can reflect a square onto itself across two diagonals and two segments that connects the middlepoints of opposite sides - 4 different lines of reflection.
