Answer:

It's A

Step-by-step explanation:

In general, the equation in point-slope form will give an expression that can substitute for "y", as that form is ...

y = [something]

_____

In specific instances, the other forms of the linear equations may work, but that is not guaranteed.

How can you use proportions to help make decisions in art, design, and magazine layouts? give two examples?

oee [108]

Proportion is defined as the comparative relationship among various elements of an image.
Simply taking a picture of jpj or png format, if the side of the picture is drag in or drag out, then the picture got disturbed, but if the same picture is drag in or drag out by its corner, then the picture composition remains the same, and thus the proportions of all the pigments remains the same.
Another example is that of using an equal proportionate amount of different colors in an image, otherwise the picture will not show its true essence and the proportionality factor among various colors of an image become the base of its originality.

A.)
original/ new-original = x/100
118,000/138000-118,000= x/100
118000/20000= x/100
118/20=x/100
20x=11800
11800/20=590
The population increased 590%

A block of iron has a mass of 3152 kg and a volume of 0.4 m².Calculate the density of the block of iron, in kg/m3.

Lisa [10]

The density of the block of iron in $kg/m^3$ is equal to 7,880.

<u>Given the following data:</u>

Mass of block = 3152 kg

Volume of block = 0.4 $m^2$

To calculate the density of the block of iron in $kg/m^3$ :

<h3>What is density?</h3>

Density can be defined as mass all over the volume of an object or body. Thus, density is equal to mass per unit volume of an object.

<h3>How to calculate density</h3>

Mathematically, the density of a substance is given by this formula;

$Density =\frac{Mass}{Volume}$

Substituting the parameters into the formula, we have;

$Density=\frac{3152}{0.4}$

Density = 7,880 $kg/m^3$

The hypotenuse of an isosceles right triangle is centimeters longer than either of its legs. Find the exact length of each side.

Varvara68 [4.7K]

Question

The hypotenuse of an isosceles right triangle is 11 centimeters longer than either of its legs. find the exact length of each side.

Answer:

$Hypotenuse:37.56$

$Other\ Legs: 26.56$

Step-by-step explanation:

Let the hypotenuse be y and the other legs be x.

So:

$y = 11 + x$

Required

Determine the exact dimension of the triangle

Using Pythagoras theorem;

$y^2 = x^2 + x^2$

$y^2 = 2x^2$

This gives:

$(11+x)^2 = 2x^2$

Open bracket

$121 + 22x + x^2= 2x^2$

Collect like terms

$2x^2 - x^2 -22x - 121 = 0$

$x^2 -22x - 121 = 0$

Using quadratic formula:

$x = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}$

$x = \frac{-(-22)\±\sqrt{(-22)^2 - 4*1*-121}}{2*1}$

$x = \frac{-(-22)\±\sqrt{968}}{2*1}$

$x = \frac{22\±31.11}{2}$

Split

$x = \frac{22+31.11}{2}\ or\ x = \frac{22-31.11}{2}\\$

$x = \frac{53.11}{2}\ or\ x = \frac{-9.11}{2}$

x can not be negative.

So:

$x = \frac{53.11}{2}$

$x = 26.56$

Recall that:

$y = 11 + x$

$y = 11 + 26.56$

$y = 37.56$

Hence, the dimensions are:

$Hypotenuse:37.56$

$Other\ Legs: 26.56$
