Dylan is rollerblading along an 8 mile trail in the forest park she stopped for water after 2.4 miles. After another 3.1 miles, she stopped for lunch. ABOUT (round) how much farther does she have to go to reach the end of the trail? SHOW YOUR WORK!

Answers

Answer 1

Answer:

Add up the amount of miles she actually reached to

2.4 + 3.1 =

5.5 = miles already traveled

And then subtract it from the 8 mile trail

8 - 5.5 =

2.5 miles

About 2.5 or 3 miles (rounded to the tenth or whole number?)

Find the area. the figure is not drawn to scale.

Answers

Answer:

Total area of the figure= $248.5cm^2$

Step-by-step explanation:

The given figure has a rectangle and a triangle:

The area of the figure= Area of rectangle+Area of triangle

Length of the rectangle= 13 cm

Width=9 cm

$Area = length * width\n\n= 13*9\n\n=121 cm^2$

Area of the triangle= 1/2 * base * Height

Height= 11 cm

Base= 13-8=5 cm

Area of the rectangle:

$(1)/(2)*5*11\n\n =(1)/(2)*55\n\n=27.5cm^2$

Total area of the figure:

$= 121+27.5=248.5 cm^2$

Answer: 144.5

Step-by-step explanation:

area of the triangle is 27.5

area of the rectangle is 117

117+27.5=144.5

There are 169 chairs in the gymnasium that need to be arranged in rows and columns. How can they be divided so that there are an equal amount of rows and columns?

Answers

By arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

To divide the 169 chairs in the gymnasium into an equal amount of rows and columns, we need to find two factors of 169 that are as close to each other as possible.

The factors of 169 are 1, 13, and 169.

The closest factors are 13 and 13, which means we can arrange the chairs in 13 rows and 13 columns to have an equal amount of chairs in each row and column.

Thus, by arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.
