What is the distance between (22,-3) and (1, -3)?

Bingel [31]

Answer:

Option D

Step-by-step explanation:

<h2>Distance between two points</h2>

The y-value of the two points is unchanged. So, the line is parralel to x-axis.

The distance will be the diffrence between the x-co ordinates.

$\sf Distance = 1 - (-2\dfrac{1}{2})$

$\sf =1+\dfrac{5}{2}\\\\= \dfrac{2}{2}+\dfrac{5}{2}\\\\=\dfrac{7}{2}\\\\=3\dfrac{1}{2}$

Kelvin rolls a dice twice. The first number he gets is 4. The sum of the two numbers is smaller than 8. Which number CANNOT be t

VLD [36.1K]

Answer:

5, 6

Step-by-step explanation:

When Kelvin rolls the dice twice, he can't get more than a 4 because if he did, the sum of the two numbers would be more than a 8. So, the numbers that cannot be the second number is 5 and 6.

An open box is made from a 20 cm x 3 cm piece of tin by cutting a square from each corner and folding up the edges. The area of

Marta_Voda [28]

Answer:

Length of the final sides: 6 cm and 16 cm

Step-by-step explanation:

The lengths of the sides of the original box are

$L=20 cm\\W=10 cm$

Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:

$L'=L-2x\\W'=W-2x$

We also know that the area is

$A=96 cm^2$

And the area can be written as product of length and width, therefore:

$A=L'W'$

So we find:

$A=(L-2x)(W-2x)\\96=(20-2x)(10-2x)$

Solving for x,

$96=200-20x-40x+4x^2\\4x^2-60x+104=0\\\\x^2-15x-26=0$

Which has two solutions:

x = 13 cm (this is larger than the initial length of the width, therefore we discard it)

x = 2 cm

So, the length of the new sides are

$L=20-2x=20-2(2)=16 cm\\W=10-2x=10-2(2)=6 cm$

What is the value of x?

JulijaS [17]

Answer:

The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa"Step-by-step explanation:
