Finding perimeter and area

Mathematics
1 answer:
Korvikt [17]3 years ago
4 0

Answer: The perimeter of a two-dimensional shape is the distance around the shape. It is found by adding up all the sides (as long as they are all the same unit). The area of a two-dimensional shape is found by counting the number of squares that cover the shape.

A turtle can walk 1/12 of a kilometer in an hour the turtle is 1/5 of a kilometer away from a pond
34kurt

Answer:

2\frac{2}{5}\ h

Step-by-step explanation:

we know that

A turtle can walk 1/12 of a kilometer in an hour

so

by proportion

Find how long will it take the turtle to reach the pond (1/5 km)

\frac{1}{(1/12)}\frac{h}{km}=\frac{x}{(1/5)}\frac{h}{km} \\ \\x=\frac{(1/5)}{(1/12)} \\ \\x=\frac{12}{5}\ h

Convert to mixed number

\frac{12}{5}\ h=\frac{10}{5}+\frac{2}{5}=2\frac{2}{5}\ h

Explain why are whole numbers are rational numbers ​
Reptile [31]

Answer:

Every whole number is a rational number: for example, 3=31. So it is rational. Every whole number n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every whole number as a fraction of integers, and hence it is rational.

Step-by-step explanation:

hope this helps

<h3>What Long division method?</h3>

Long division is a method for dividing one large multi digit number into another large multi digit number.

Given:

f(x)=  x²+2x+1

g(x)= x+1

The steps to divide the polynomial is :

  • Divide the leading term of the dividend by the leading term of the divisor: x²/x=x.
  • Multiply it by the divisor: x(x+1)=x²+x.
  • Subtract the dividend from the obtained result: (x²+2x+1)−(x²+x)=x+1.
  • Divide the leading term of the obtained remainder by the leading term of the divisor: x/x=1.
  • Multiply it by the divisor: 1(x+1)=x+1.
  • Subtract the remainder from the obtained result: (x+1)−(x+1)

evablogger [386]
The probability of choosing a blue marble is 3/6 or 1/2 because 1/3 +1/6 equals 3/6. Meaning that only 3/6 is left over for blue's probability.
