3/8 = blank/24

Answers

Answer:9

Step-by-step explanation:

3/8=x/24

3/8=x/3*8

[tex]\frac{3}{8} =\frac{\frac{x}{3} }{8}[/tex]

3=x/3

x=9

Answer:

First, we evaluate the amount that the portion has been multiplied by. We want to determine how many number 8's fit in to the number 24 because the bottom of the portion is 24.

The solution would be 3, because eight multiplied by 3 equals 24. Also because the bottom of the fraction has been multiplied by three, the top, known as the numerator, also needs to be multiplied by three. As a result, the top becomes 3 multiplied by 3, which equals 9. As a result, the portion is 9/24.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
The monthly cost of using 4 gigabytes of data on Company C's plan can be calculated using Rule C:

C(4) = $10 + $15 × 4 = $10 + $60 = $70

The monthly cost of using 4 gigabytes of data on Company D's plan can be calculated using Rule D:

D(4) = $80

What is the difference between absolute and relative error?

Answers

Absolute error and relative error are two measures of the difference between an estimated or calculated value and the true or exact value of a quantity.

The main difference between absolute and relative error is that absolute error gives the magnitude of the difference between the estimated value and the true value, while relative error gives a measure of this difference relative to the size of the true value.

Absolute error is the magnitude of the difference between the estimated or calculated value and the true value.

It is calculated as the absolute value of the difference between the estimated value and the true value. Absolute error is expressed in the same units as the quantity being measured.

Relative error, on the other hand, is the absolute error expressed as a fraction or percentage of the true value. It is calculated as the absolute error divided by the true value, and is usually expressed as a percentage.

Relative error is a useful measure when the scale of the quantity being measured varies over a wide range, or when comparing the accuracy of measurements of different quantities.

The sum of the digits of a three-digit number is 13. The tens digit, t, is 1 more than the hundreds digit, h. The units digit, u, is 3 more than the sum of the tens and hundreds digits. Which system of equations can be used to find each digit?

Answers

System of equations can be used to find each digit is option A.

Describe Equation?

An equation is a mathematical statement that shows that two expressions are equal to each other. It consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The LHS and RHS can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots.

Let's represent the hundreds, tens, and units digits as h, t, and u, respectively. Then we can use the given information to set up a system of equations:

A three-digit number has a digit sum of 13:

h + t + u = 13

One more than the hundreds digit (h) is the tens digit (t):

t = h + 1

The digit in the units, u, is 3 greater than the total of the digits in the tens and hundreds:

u = t + h + 3

Therefore, the correct system of equations is:

h + t + u = 13

t = h + 1

u = t + h + 3

Therefore, the answer is (A).

12 Colin used 2 5/6 sheets of paper and completed 1/6 of his report. How many pages was the completed report?

Answers

Answer:

below

Step-by-step explanation:

He needs 6 times as many as 1/6 th  to have a complete report

  6 * 2 5/6 =   6  * 17/6 = 102/6 = 17 pages total

If Colin used 2 5/6 sheets of paper to complete 1/6 of his report, we can use this information to find out how many sheets he will need to complete the entire report.

Let's start by finding out how many sheets of paper Colin used for each 1/6 of the report. We can divide the total number of sheets he used (2 5/6) by the fraction of the report he completed (1/6):

(2 5/6) ÷ (1/6) = (17/6) ÷ (1/6) = 17

So Colin used 17 sheets of paper to complete 1/6 of the report.

To find out how many pages the completed report will be, we need to multiply the number of sheets used to complete 1/6 of the report by the total number of 1/6ths in the completed report. Since 1/6 represents the fraction of the report that Colin has completed, there are 5/6 of the report left to complete:

1/6 + 5/6 = 6/6 = 1 (the completed report)

So there are a total of 6 1/6ths in the completed report. To find the total number of sheets, we can multiply the number of sheets used to complete 1/6 of the report by 6:

17 sheets x 6 = 102

Therefore, Colin will need a total of 102 sheets of paper to complete the entire report.

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:

An equation of the line that passes through the points (2,1) and (6, -3) is,

y - 1 = (-3 - 1)/(6 - 2)(x - 2)

y - 1 = -1(x - 2)

y - 1 = -x + 2

y = -x + 3

The slope of the perpendicular bisector that goes through the line y = -x + 3 is,

= -(1/-1)

= 1

And the required line passes through (2 + 6/2, 1-3/2) = (4, -1) and have slope 1,

So, the equation of the line is,

y + 1 = 1(x - 4)

y = x - 5

Therefore, the equation is y = x - 5.

If this rectangle is dilated using a scale factor of through point b, what is the result?.

Answers

The result of dilating a rectangle using a scale factor of 1/2 through point B will be a new rectangle with half the length and width of the original rectangle, centered around point B.

When a rectangle is dilated using a scale factor of 1/2, it means that the size of the rectangle is reduced by half.

This can be achieved by multiplying the dimensions of the rectangle by the scale factor. In the case of a dilation through point B, the new rectangle will be centered around point B and its length and width will be half of the original dimensions.

In mathematical terms, let's assume that the original rectangle has length "l" and width "w". The new rectangle after the dilation with a scale factor of 1/2 will have a length of (1/2)l and a width of (1/2)w.

To find the new coordinates of the rectangle, we need to subtract (1/4)l and (1/4)w from the original x and y coordinates respectively.

If the original rectangle has a length of 4 and a width of 2, then the new rectangle after the dilation with a scale factor of 1/2 will have a length of 2 and a width of 1.

The new x and y coordinates will be x-1 and y-0.5 respectively.

The labor supply curve is upward sloping and shows the quantity of labor supplied at different wages. Mathematically, this is represented as the equation: Qs = a + bw, where Qs is the quantity of labor supplied, a is a constant, b is the elasticity of labor supply, and w is the wage. The labor demand curve is downward sloping and shows the quantity of labor demanded at different wages.

The cabin that jake and his friends are staying at charges an initial fee plus the cost per night. The relationship between the cost and number of nights is shown in the graph below. Find the Cost Per Night (m) and the Initial Fee (b).

Answers

Using the slope intercept form of the line, cost per night (m) is 75 and the initial fee (b) that the cabin charges is 50.

What is the Equation of line in Slope Intercept form?

Equation of a line in slope intercept form is

y = mx + b

Here m is the slope of the line and b is the y intercept, which is the y coordinate of the point where it touches the Y axis.

The cabin that Jake and his friends are staying at charges an initial fee plus the cost per night.

Given graph is a linear relationship between the total cost, y, and number of nights, x.

Let initial fee be b and cost per night be m.

So the equation will be of the form,

Total cost = Initial fee + (cost per night × number of nights)

y = b + mx

Comparing this with slope intercept form, initial fee is the y intercept and cost per night is the slope.

From the graph, we have a point (0, 50).

y intercept = 50

So initial fee = 50

Consider (0, 50) and (2, 200).

Slope = (200 - 50) / (2 - 0) = 75

So cost per night = 75

Hence cost per night is 75 and the initial fee is 50.

Answers

Answer:

number of glasses he bought = 60

Step-by-step explanation:

Let the variable x represent the number of glasses he bought

Total cost of x glasses at Rs. 12 each = 12x

5 glasses broke so remaining number of glasses = x- 5

He sold this quantity of glasses for Rs. 16 each

Total sale price of (x - 5) glasses = 16(x - 5)

Total profit = Total sales - Total cost = 160

=> 16(x - 5) - 12x = 16

Expand brackets for 16(x - 5): 16x - 16 x 5 = 16x - 80

Therefore we get

16x - 80- 12x = 160

4x - 80 = 160

Add 80 on both sides:

What was the Economic Growth and Tax Relief Reconciliation Act of 2001? Find the magnitude E of the electric field at a distance r from the axis of the cylinder for r < r0. Remember that we've chosen the label l to represent the length of the cylindrical Gaussian surface. Express your answer in terms of some or all of variables rho, r, r0, l, and epsilon0. E = pr/2e0If you repeated your calculation from Part C for r = r0, you would find that the magnitude of the electric field on the surface of the rod is E surface = rho r0 / 2epsilon0 Now rewrite the expression for E surface in terms of lambda, the linear charge density on the rod. Express your answer in terms of lambda, r0, and epsilon0. Your answer should not contain the variable rho. 1 try left Assume the variables principal and divisor have been assigned integer values. Write a statement that computes the remainder of principal divided by divisor, and assigns the result to a variable named result.
