Answer:

8 1/2 miles

Step-by-step explanation:

Please use " ' " to indicate fractions:

Andrea rode her bike 3 2/3 miles on saturday and 4 5/6 miles on sunday.

Add together 3 2/3 and 4 5/6.  The LCD is 6, so 3 2/3 should be rewritten as 3 4/6.  Now 3 4/6 and 4 5/6 have the same denominator, 6.

 3 4/6

+4 5/6

-----------

 7  9/6.    Note that 9/6 = 1 1/2, so rewrite

7  9/6 as 8 3/6, or 8 1/2.

She biked 8 1/2 miles in all.

Can someone help me in this plssss I really need it
kompoz [17]

Answer:

\boxed{-3xy^{2}\sqrt [3] {2x^{2}}}

Step-by-step explanation:

Your expression is

\sqrt [3] {-54x^{5}y^{6}}

Here's how I would simplify it.

\begin{array}{rcll}\sqrt [3] {-54x^{5}y^{6}} & = & \sqrt [3] {(-1)^{3}\times 2 \times 27 \times x^{2} \times x^{3} \times y^{6}} & \text{Factored the cubes}\\& = & \sqrt [3] {(-1)^{3} \times 3^{3}\times x^{3} \times y^{6}\times 2 \times x^{2}} & \text{Grouped the cubes}\\\end{array}

\begin{array}{rcll}& = & \sqrt [3] {(-1)^{3} \times {3^{3}\times x^{3} \times y^{6}}} \times\sqrt [3] { 2 \times x^{2}} & \text{Separated the cubes}\\&=& \mathbf{-3xy^{2}\sqrt [3] {2x^{2}}} & \text{Took cube roots}\\\end{array}

\text{The simplified expression is $\boxed{\mathbf{-3xy^{2}\sqrt [3] {2x^{2}}}}$}

Area of the rectangle

= l  \times b

= 8 \times 6

= 48 {in}^{2}

Area of the semicircles

= 2 \times ( \frac{1}{2} \pi {r}^{2} )

= \pi {r}^{2}

= \pi {3}^{2}

= 9\pi

= 9 \times 3.14

= 28.26 {in}^{2}

Area of the figure

= 48 + 28.26

= 76.26 {in}^{2}

= 76.3in²

Last week salazar played 13 more tennis games than perry. if they played a combined total of 53 games. How many games did salaza
d1i1m1o1n [39]

If last week Salazar played 13 more tennis games than Perry and they played a combined total of 53 games, then Salazar played a total of 33 games.

Let the total number of games played by Perry be x.

It is given that, Salazar played 13 more tennis games than Perry.

⇒ Total games played by Salazar = x + 13

Also, Salazar and Perry played a combined of 53 games.

Hence, total number of tennis games played by Salazar and Perry = 53

⇒ Games played by Salazar + Games played by Perry = 53

⇒  x + (x + 13) = 53

2x + 13 = 53

2x = 53 - 13

2x = 40

x = 40 / 2

x = 20

Therefore, total number of games played by Salazar = x+13

= 20 + 13

= 33

Thus, Salazar played total 33 games.
