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.

Name 2 strategies that you can use to find the area of a shape

Answers

1. Multiply the dimensions

2. Make two smaller shapes and multiply each dimensions then add the answers together to get the final answer

First, it depends what shape it is.

To find the area of the:

square/rectangle: L x W (length times width)\

Triangle: 1/2 x b x h (One half times base times height)

Parallelogram: b x h (base times height)

Circle: $\pi$ x r^2 (Pi times radius to the power of 2)

Trapezoid: 1/2 x (a+b) x h (One-half times Base 1 plus Base two times height

Disclaimer: These are the areas for MOST shapes, not all.

hope this helpeed :)

Parallel lines and intersecting lines are perpendicular lines explained

Answers

parallel lines are two lines in the same plane that will never intersect with each other. Intersecting lines are lines that pass through each other at some point. perpendicular lines are lines that intersect each other at 90 degree angles.
I hope this helps.

parallel lines never touch, intersecting lines cross, and perpendicular lines cross at a 90 degree angle. Hope that helped.

Why is a number raised to the zero power ALWAYS one and never any other number?

Answers

Do you know how to simplify, let's say for example, x⁵/x² ?

When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator. So x⁵/x² = x³ .

Now look at x⁷/x⁷ . From that same handy tip, x⁷/x⁷ = x⁰ .

BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '. So x⁰ = 1 , no matter what 'x' happens to be.

Does that do anything for you ?

Is the product of a fraction that is less than one and any whole number less than or greater than the while number?Explain your thinking.

Answers

Less. A whole number times 1/2 is half of the whole number, a whole number times 1/4 is a fourth of the whole number. 6x1/2=3, 6x1/4=1.5 :)
