Using property find <br>a.3/5×-2/7+4/5-3/10×2/7​
Sedaia [141]

Here the answer is 19/35

Step-by-step explanation:

\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}

We will apply BODMAS rule

In this rule multiplication comes before add and subtraction

= \frac{-6}{35} + \frac{4}{5} - \frac{3}{35}

= \frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})

= \frac{4}{5} -  \frac{9}{35}

= \frac{4 X 7}{5 X 7} -\frac{9}{35}

= \frac{28}{35} - \frac{9}{35}

= \frac{19}{35}

In a right triangle the lengths of the legs are a and b. Find the length of a hypotenuse, if: a=3, b=4;
prohojiy [21]

Answer:

The hypotenuse is 5

Step-by-step explanation:

We can use the Pythagorean theorem to find the hypotenuse of a right triangle

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

3^2 +4^2 =c^2

9+16=c^2

25=c^2

Take the square root of each side

sqrt(25) =sqrt(c^2)

5 = c

Each square on Olivia's chessboard is 11 square centimeters. A chessboard has 8 square on each side. To the nearest tenth, what
prisoha [69]
The chessboard is about 26.4 centimeters long. to find the answer you need to know the length of one side of a square, which is about 3.3 centimeters, because the area is 11, so the square root of 11 is about 3.3 centimeters. there are 8 squares, so you have to multiply 8 times 3.3 which equals 26.4.
