What shapes will have diagonals that are not lines of symmetry

Answers

When a mirror is placed along the diagonal of a rectangle, the result does not look the same as the original rectangle, so the diagonal is not a line of symmetry. This new shape --- the combination of the triangular half of the original rectangle and its image in the mirror --- is called a kite.

The radius of a circle is 5 miles. What is the circumference?

Answers

Answer:

31.4

Step-by-step explanation:

Circumference = 2 x Radius x π. π = Pi = 3.14, thus, the math to calculate the circumference of a circle with a radius of 5 is: 2 x 5 x 3.14 = 31.4. And the answer to the circumference of a circle with a radius of 5 is approximately: ≈ 31.4.

There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population density? (Use 3.14 for π) Area of a circle = πr2 0.02 bacteria per square millimeter 0.42 bacteria per square millimeter 2.39 bacteria per square millimeter 52.5 bacteria per square millimeter

Answers

The population density is 0.418 bacteria per mm².

What is Area of Circle?

A circle's area is the area that it takes up in a two-dimensional plane.

The formula for area of circle is, A = πr², where r is the radius of the circle. The unit of area is the square unit, such as m², cm², etc.

Given:

Radius= 40 mm

So, Area of petri dish = πr²

= 3.14x(40 mm)²

= 3.14 x 1600 mm²

= 5024 mm²

and, Population Density

= 2100 / 5024

= 0.418 bacteria per mm²

Hence, the population density is 0.418 bacteria per mm².

#SPJ6

Population Density = # bacteria/area

Area = πr^2
= 3.14•(40 mm)^2
= 3.14•1600 mm^2
= 5024 mm^2

Pop Density = 2100 / 5024
= 0.418 bacteria per mm^2

The answer is 0.42 bacteria per square mm

There are 75 students enrolled in a camp. The day before the camp begins, 8% of the students cancel. How many students actually attend the camp?Enter the correct answer in the box.

Answers

Answer: 69

Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)

Then you simplify which will then get you 6.

Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.
