100.77 round to the nearest tenth of a square mile

2 answers:

7 0

The tenth place is the one just to the right of the 0. This means that we have to look at the hundreths place which is 2 places to the right of the 0. If the number is greater than or equal to 5 then we round up. The number in the hundreths place is 7, which is above 5 we round the tenths place up to 8.

This would make your answer 100.8

Explain how to find a common denominator of 3/4 and 1/5 what is a common denominator of 3/4 and 1/5 show how you can rename 3/4

Paul [167]

Answer:

Common denominator = 20

New fractions are: $\dfrac{15}{20}\ and\ \dfrac{4}{20}$

Step-by-step explanation:

Given:

The fractions are given as:

$\dfrac{3}{4}\ and\ \dfrac{1}{5}$

The denominators of the first fraction is 4 and that of the second fraction is 5.

In order to find the common denominator for 4 and 5, we have to find the least common multiple of each of the numbers.

Multiples of 4 = 4, 8, 12, 16, 20, 24, 28,....

Multiples of 5 = 5, 10, 15, 20, 25, 30,....

Therefore, the least common multiple of 4 and 5 is 20. So, the common denominator is 20.

Now, multiply the numerator and denominator of each fraction by the same suitable number such that the denominator becomes 20.

So, for the first fraction, 4 is in the denominator.

So, 4 when multiplied by 5 gives 20.

So, we multiply the numerator and denominator of first fraction by 5. This gives,

$\dfrac{3}{4}=\dfrac{3\times 5}{4\times 5}=\dfrac{15}{20}$

Now, for the second fraction, 5 is in the denominator.

So, 5 when multiplied by 4 gives 20.

So, we multiply the numerator and denominator of first fraction by 4. This gives,

$\dfrac{1}{5}=\dfrac{1\times 4}{5\times 4}=\dfrac{4}{20}$

Therefore, the new fractions after making the denominators same are:

$\dfrac{15}{20}\ and\ \dfrac{4}{20}$

If a rectangle measures 21 centimeters by 28 centimeters what is the length in centimeters of the diagonal of the rectangle

SOVA2 [1]

Answer:

35cm

Step-by-step explanation:

Given data

Length= 21cm

Width= 28cm

Diagonal= ???

Applying Pythagoras theorem

D^2= L^2+W^2

D^2= 21^2+28^2

D^2= 441+784

D^2= 1225

D= √1225

D= 35cm

Hence the diagonal is 35cm
