The value of x is 25 cm, which was calculated by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm). solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.

x = 25 cm

We can calculate the value of x by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm).

Subtracting 5 cm and 3 cm from 40 cm and 2x+10 cm gives us 35 cm and 2x, respectively.

We can then solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.

Dividing both sides by 2 gives us x = -17.5 cm.

Since x must be a positive value, the correct answer is x = 25 cm.

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

When you roll a di, there is a  [tex]\frac{1}{2}[/tex] chance you will either get an even or an odd number. Since this needs to happen twice, we will square this fraction, giving us:

[tex](\frac{1}{2}) ^{2} = \frac{1}{4}[/tex]

Answer:

[tex]-11\sqrt{5}-11\sqrt{6}[/tex]

Step-by-step explanation:

Given expression:

[tex]\dfrac{11}{\sqrt{5}-\sqrt{6}}[/tex]

To rationalize the denominator, multiply the numerator and denominator by the conjugate of the denominator.

The conjugate of a binomial is where we change the sign between the two terms of the binomial.  So the conjugate of (√5 - √6) is  (√5 + √6).

[tex]\implies \dfrac{11}{\sqrt{5}-\sqrt{6}} \cdot \dfrac{\sqrt{5}+\sqrt{6}}{\sqrt{5}+\sqrt{6}}[/tex]

[tex]\implies \dfrac{11(\sqrt{5}+\sqrt{6})}{(\sqrt{5}-\sqrt{6})(\sqrt{5}+\sqrt{6})}[/tex]

[tex]\implies \dfrac{11(\sqrt{5}+\sqrt{6})}{\sqrt{5}\sqrt{5}+\sqrt{5}\sqrt{6}-\sqrt{6}\sqrt{5}-\sqrt{6}\sqrt{6}}[/tex]

[tex]\implies \dfrac{11(\sqrt{5}+\sqrt{6})}{5-6}[/tex]

[tex]\implies \dfrac{11(\sqrt{5}+\sqrt{6})}{-1}[/tex]

[tex]\implies -11(\sqrt{5}+\sqrt{6})[/tex]

[tex]\implies -11\sqrt{5}-11\sqrt{6}[/tex]

Reason:

The ratio of white to green is 2:5.

The ratio of green to blue is 1:3, which can be scaled up to 5:15 after multiplying both parts by 5.

Write out the ratios 2:5 and 5:15 to notice that we have the inner '5's match up. This gives a triple ratio of 2:5:15 which is the ratio of white to green to blue in that exact order.

Ignoring the middle value gives the ratio of white to blue being 2:15

For every 2 white beads, there are 15 blue beads.

The sum of all possible values of n is 448.

Let n be a positive number.

Answer: In order to calculate the bill for this household, we will need first to determine the total amount of water consumed in liters. Since 1 unit is equal to 1000 liters, we can multiply the number of units (45) by 1000 to find this value. 45 units * 1000 liters/unit = 45,000 liters

Next, we will need to determine the cost of the water consumed. Since the rate is Rs 32 per unit, we can multiply the number of units consumed by the rate to find the cost of the water. 45 units * Rs 32/unit = Rs 1440

Since the household consumed less than 10 units of water, they will be charged the minimum charge of Rs 100.

Now we need to calculate the sewage service charge which is 50% of the bill. So, Rs 1440 * 0.5 = Rs 720

Now we need to add the sewage service charge with the water bill and get the final bill. Rs 1440 + Rs 720 = Rs 2160

Since the payment is made within one month of the bill being issued, there is a 3% discount so that the final bill will be Rs 2160 - (3/100)*Rs 2160 = Rs 2094

So, the payment of the bill including a 50% sewage service charge if the payment is made within one month of the bill being issued would be Rs 2094.

Therefore , the solution of the given problem of linear equation comes out to be chris sold = g/8 -17.

A model of linear regression is one that follows the algebraic formula y=mx+b. The y-intercept is m, and the slope is B. Although both y and x are distinct parameters, the foregoing sentence is sometimes referred to as a "mathematical equation with two variables." Bivariate linear equations only have two variables. Application areas of linear equations result in zero in all cases. The equation for one linear equation is Y=mx+b where m is the slope and b is the y-intercept. Y=mx+b is the formula for an equation, where m stands for slopes and b for the y-intercept.

Answer:

U' (- 1, 3 )

Step-by-step explanation:

under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

U (- 1, - 3 ) → U' (- 1, 3 )

Step-by-step explanation:

linear functions (or lines) have really only 2 attributes :

the slope (indicating the inclination of the line).

the y-intercept (the intersection with the y-axis) or the x-intercept. either way, they show the actual position of the line.

the lines intersect at one point, if they have different slopes.

they intersect at infinitely many points, if the slope and the y- or x-intercepts are equal (ultimately that means the lines are identical, so every point is an intersection point).

if they have the same slope but different y- or x-intercepts, it means they are parallel and will never intersect.

The solution to given equation (3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5

is x = -1

Consider given equation.

(3/4)x + 3 - 2x = -(1/4) + (1/2)x + 5

We need to solve this equation.

First we combine the like terms on each side of the equation.

(3/4 - 2)x + 3 = (-1/4 + 5) + (1/2)x

Simplify each side of the above equation.

(-5/4)x + 3 = 19/4 + (1/2)x

Now subtract (1/2)x from each side,

(-5/4)x + 3 - (1/2)x = 19/4 + (1/2)x - (1/2)x

Simplify each side

(-5/4 - 1/2)x + 3 = 19/4 + 0

(-7/4)x + 3 = 19/4

Add -3 to each side of the equation.

(-7/4)x + 3 - 3= 19/4 - 3

(-7/4)x = 7/4

The average of children per household is approximately 2.1387931034482758.

What is average ?

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

To compute the average number of children per household, you would add up the total number of children in all the surveyed households and divide that number by the total number of households surveyed. You can use the following formula:

Average = (Sum of (children x frequency)) / (Total number of households surveyed)

Children Frequency Children x Frequency

0         2                 0

1         8                 8

2         10                 20

3         4                 12

4         3                 12

5         2                 10

Sum of (children x frequency) = 8 + 20 + 12 + 12 + 10 = 62

Total number of households surveyed = 2 + 8 + 10 + 4 + 3 + 2 = 29

Average = 62 / 29 = 2.1387931034482758

Answer:

Step-by-step explanation:

it is not possible for a cylinder to have a surface area greater than 100 cm² and a volume less than 100 cm³. The surface area of a cylinder is given by the formula 2πr² + 2πrh, where r is the radius of the base and h is the height of the cylinder. A cylinder with a surface area greater than 100 cm² would have to have a relatively large radius and/or height.

On the other hand, the volume of a cylinder is given by the formula πr²h. Even if the radius is small and the height is big, the product of both will be bigger than 100 cm³. Therefore, it is not possible for a cylinder to have a surface area greater than 100 cm² and a volume less than 100 cm³.

Answer: The measure of an exterior angle of a regular polygon is given by the formula:

(n-2) * 180 / n

Where n is the number of sides of the polygon.

So, if the measure of an exterior angle of a polygon is 36 degrees, we can set up the equation:

(n-2) * 180 / n = 36

To find the measure of an interior angle, we can use the formula:

(n-2) * 180 / n = (n-2) * 180 / n

So, if the measure of an exterior angle is 36, the measure of an interior angle would be:

(n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n

To find the number of sides, we can use the formula:

n = (180 / (180-x))

So, if the measure of an exterior angle is 36, the number of sides would be:

n = (180 / (180-36)) = (180 / 144) = 5

Therefore, a regular polygon with an exterior angle measure of 36 degrees has 5 sides and an interior angle measure of 144 degrees.
