Ava is 23 cm taller than Olivia,and Olivia is half the height of Lucas. If Lucas is 1.78 m tall,how tall are Ava and Olivia? Express their heights in centimeters.

Answers

  • Ava's height is 89 cm
  • Olivia's height is 112 cm

Further explanation

Given:

  • Ava is 23 cm taller than Olivia
  • Olivia is half the height of Lucas
  • Lucas is 1.78 m tall

Question:

How tall are Ava and Olivia?

Express their heights in centimeters.

Problem solving:

From the information above, only Lucas's tall has known at 1.78 m.

Because Olivia is half the height of Lucas, then we must multiply Lucas's height with ¹/₂ to get Olivia's tall.

\boxed{ \ Olivia's \ height = (1)/(2) * 1.78 \ m \ }

Or, we can halve Lucas's height as follows:

\boxed{ \ Olivia's \ height = 1.78 \ m / 2 \ }

Thus, Olivia's height is\boxed{ \ 0.89 \ meters \rightarrow 89 \ cm \ }

Next, we find out Ava's height.

Because Ava's is 23 cm taller than Olivia’s, then we must add Olivia’s height with 23 cm to get Ava's height.

Ava's height = 89 cm + 23 cm

Thus, Ava's height is\boxed{ \ 112 \ cm \rightarrow 1.12 \ meters \ }

We have to express their height in centimeters. Recall that 1 m = 100 cm.

Conclusion

  • Ava's height is 0.89 m or 89 cm
  • Olivia's height is 1.12 m or 112 cm
  • Lucas's height is 1.78 m or 178 cm

Keywords: Ava is 23 cm taller than Olivia, half the height of Lucas, 1.78 m tall, multiply, express their heights in centimeters.

Thus, the height of ava and olivia is \boxed{112\text{ cm}\text{ and }89\text{ cm}} respectively.

Further explanation:

It is given that height of ava is 23\text{ centimeter} more than the height than the height of olivia and the height of olivia is half of the height of lucas.

Consider the height of ava, olivia and lucas as x,y and z.

The height of the lucas is given as 1.78\text{ meter}.

This implies that the value of z is as follows:

\boxed{z=1.78}

Since, the height of lucas is given in meter so, it is necessary to convert the unit into centimeter.

The height of lucas is converted into centimeter unit as follows:

\begin{aligned}1\text{ meter}&\rightarrow 100\text{ centimeter}\n1.78\text{ meter}&\rightarrow 1.78*100=178\text{ centimeter}\end{aligned}

Since, the height of olivia is half of the height of lucas so, the equation formed is as follows:

\boxed{y=(z)/(2)}

Substitute 178 for the z in the above equation.

\begin{aligned}y&=(178)/(2)\n&=89\end{aligned}

Therefore, the value of y is 89.

This implies that the height of olivia is 89\text{ centimeter}.

It is given that height of ava is 23\text{ centimeter} more than the height than the height of olivia so, the equation formed is as follows:

\boxed{x=23+y}

Substitute 89 for y in the above equation.

\begin{aligned}x&=23+89\n&=112\end{aligned}

This implies that the height of ava is 112\text{ centimeters}.

Thus, the height of ava and olivia is \boxed{112\text{ cm}\text{ and }89\text{ cm}} respectively.

The answer is that the team has to have 25 wins.

Step-by-step explanation:

since the ratio is 2 losses to 5 wins, if you divide 10 by 2, you get 5. Multiply 5 by 5, since it is the other side of the ration, and you'll get 25 wins.

Ronald paid $162 for 6 tickets to a basketball game during the game he noticed that his friend paid 130 for 5 tickets the price of each ticket was $26 was Ronald overcharge explain

Answers

As for this problem, we take into consideration that it was stated that each ticket costs $26. So if Ronald bought 6 tickets, the cost for all the tickets should have been just $132. His friend bought 5 tickets which was only at $80. Both him and his friend were overcharged. Ronald was overcharged by $30 and his friend was overcharged by $40. They generally paid another ticket with a little more to top on that. This is also an important lesson that since you know the price, you can calculate it itself to avoid being overcharged.
