A square has an area of 90 square inches. What is the length of a side of the square in inches?

The recipe of flour and sugar can be given as an example where we will get the ratio as 4 : 1.

The example is with flour and sugar

Let

x = the number of cups of flour

y =  the number of cups of sugar

We know that:

Ratio means the comparison between the two values.

Ratio = x / y

Now, we can let

x = 1 / 2 cups of flour

y = 1 / 8 cups of sugar

Ratio will be

= 1 / 2 : 1 / 8

= 8 : 2

= 4 : 1

Therefore, the recipe of flour and sugar can be given as an example where we will get the ratio as 4 : 1.

The height of Andy 68 inches is greater than the minimum requirement which is 54 inches. Yes, And can ride.

Conversion means to convert the same thing into different units.

The sign in front of the Electric storm roller coaster states that all riders must be at least 54 inches tall to ride. If Andy is 5 feet 8 inches tall.

Convert height of Andy into inches only. Then we have

⇒ 5 feet + 8 inches

⇒ 5 x 12 inches + 8 inches

⇒ (60 + 8) inches

⇒ 68 inches

The height of Andy 68 inches is greater than the minimum requirement which is 54 inches. Yes, And can ride.

Answer:

x = -16

Step-by-step explanation:

The interval of x-values over which the function is decreasing is ( - 1,1).

In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.

By differentiating the given function, it is possible to find the range of x-values across which the provided function is decreasing: (-1,1).

Given function is , f(x) = x³ – 3x – 2.

The following steps can be used in order to determine the interval in which the given function is decreasing:-

Step 1 - Write the given function.

f(x) = x³ – 3x – 2.

Step 2 - Now, differentiate the above function with respect to 'x'.

F'(x) = 3x² - 3

Step 3 - Now, equate the above expression to zero.

x² = 1

x = 1 or -1

Therefore, the interval of x-values over which the function is decreasing is ( - 1,1).

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx      —-- 1

Now, find k for given x = 3 / 4 and y = 5 / 3, we need to put these values in equation 1, i.e.

5 / 3 = k(3 / 4)

k = (5 × 4) / 9

k = 20 / 9

Further calculate x for given y = ½ and constant of proportion = 20/9i.e.

½ = (20 / 9)x

x = 9 / 40

Hence, the required value of x is 9 / 40.

First let's find all the inner angles of the triangle.

124+DCB=180 ==> Angles DCB and 124 lie on a straight line. Straight lines measure 180 degrees and are called straight angles.

124+DCB=180

A simplified expression for the amount, in dollars, that the company is paid is $3,500+273d.

Given that, a company rents out 14 food booths and 21 game booths at the county fair. The fee for a food booth is $175 plus $9 per day. The fee for a game booth is $50 plus $8 per day.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given, the fair lasts for d days, and all the booths are rented for the entire time.

So, Food Booth Fee can be calculated as follows:

14(175+9d)

=2,450+126d

Game Booth Fee can be calculated as follows:

=21(50+8d)

=1050+168d

So, the total Food and Game Booth Fees:

The solution of the given equation 5-4t = 12 is at t = -7/4.

According to the given question.

We have a linear equation in one variable.

5 - 4t = 12

As we know that, linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, th esolution for the given equation 5 - 4t = 12 is given by

5 - 4t = 12

⇒ -4t = 12 - 5      (subtracting 5 from both the sides)

⇒ -4t = 7

⇒ -t = 7/4          (dividing both the sides by 4)

⇒ t = -7/4

Hence, the solution of the given equation 5-4t = 12 is at t = -7/4.

Answer:

7.50c+12a<or=200 (you would have a inequality since that is the maximum number you could pay and no other information is given)

the graph is above and the inequality in slop intercept format is y= -5/8x+ 16 2/3

Solutions for c: 0 <or= c <or= 26* *(since that is the maximum whole number you can have for $200)

Solutions for a: 0 <or= a <or= 16* *(since that is the maximum whole number you can have for $200)

Note: In order for find other solutions your cordatnate has to be a whole number (that is positive or zero) within the red area shaded. However there are many examples given for answer purposes.

Step-by-step explanation:

$7.50 is the price of each children tickets and $12 is the price of each adult tickets and when combined equal to $200 so you can multiply the variables to get 7.5c+12a <or= 200.

To graph the inequality there's two ways;

Way 1: Change from standerd form to slope intercept form

Way 2: Isolate your variables to get your x and y intercept

The equation of the line in point-slope form, which passes through the pair of points located at (-4 , -3) and (2 , 7), is y + 3 = 5/3(x + 4).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (-4 , -3) and (2 , 7).

m = (y2 - y1)/(x2 - x1)

m = (7 - -3)/(2 - -4)

m = 10/6

m = 5/3

Using the point slope form, plug in the values of the slope and Point A to set up the equation.

(y - y1) = m(x - x1)

where m = 5/3 and (x1 , y1) = (-4 , -3)

(y - -3) = 5/3(x - -4)

y + 3 = 5/3(x + 4)

Where,

  a = first number of the series

  r = common ratio

 n = number of series

 [tex]a_{1}[/tex] = a

 [tex]a_{2}[/tex] = ar

 [tex]a_{3}[/tex] = a [tex]r^{2}[/tex]
