Seven more than the quotient of a number and 3 is 10? What is the number?

Answers

Answer 1

The number is 9.

Which one of the three types of equations are they?

The three main types of linear equations are the standard form, the point-slope form, and the slope-intercept form.

We can begin by converting the following phrase into an equation:

The formula for "seven bigger than the product of a number and three" is as follows:

x/3 + 7

where x stands in for the unidentified number.

Seven more than the result of a number and three equals 10, according to the following formula.

x/3 + 7 = 10

When you take 7 out of both sides of the equation, you get:

x/3 = 3

When both sides of the equation are multiplied by 3, the result is:

x = 9

Hence, the answer is 9.

Solve 6x+14x+5=5(4x+1) and write a word problem to the equation or any relevant forms of it represents.

Answers

After solving the given expression, the value of x is 5.

What exactly are expressions?

An expression in mathematics is a set of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that may be evaluated to generate a value. Expressions can be simple or complicated, with one or more variables involved.

Now,

To solve the equation 6x+14x+5=5(4x+1), we first need to simplify both sides of the equation using the distributive property of multiplication:

6x + 14x + 5 = 20x + 5

Now we can simplify further by subtracting 20x and 5 from both sides of the equation:

6x + 14x - 20x = 0 - 5

Simplifying again:

x = -5

Finally, we can solve for x by multiplying both sides by -1:

x = 5

Therefore, the solution to the equation 6x+14x+5=5(4x+1) is x=5.

Word problem:

A clothing store sells two types of shirts: T-shirts and polo shirts. The store makes a profit of $6 on each T-shirt sold and a profit of $14 on each polo shirt sold. Last week, the store sold a total of 5 shirts and made a total profit of $25. If x represents the number of T-shirts sold, write an equation to represent the situation.

Solution:

Let x be the number of T-shirts sold, then the number of polo shirts sold is 5 - x (since a total of 5 shirts were sold). The total profit from selling x T-shirts and (5-x) polo shirts can be calculated as:

Profit = (profit per T-shirt x number of T-shirts) + (profit per polo shirt x number of polo shirts)

Profit = (6x) + (14(5-x))

Profit = 6x + 70 - 14x

Profit = -8x + 70

Since the total profit is given as $25, we can write the equation:

-8x + 70 = 25

Simplifying:

-8x = -45

x = 5.625

Since we can't sell a fraction of a shirt, we need to round down to the nearest integer. Therefore, the store sold 5 T-shirts.

The radius r for the circle C is equal to 39 using the Pythagoras rule for the right triangle ABC

How to evaluate for the radius using Pythagoras rule

Since the line AB is tangent to the circle at point B, then the triangle ABC is a right triangle and the Pythagoras rule can be applied as follows:

(50 + r)² = r² + 80²

r² = (50 + r)² - 80²

r² = (50 + r - 80)(50 + r + 80) {difference of two square}

r² = (r - 30)(r + 130)

r² = r² + 130r - 30r - 3900 {expansion of brackets}

r² - r² + 130r - 30r = 3900 {collect like terms}

100r = 3900

r = 3900/100 {divide through by 100}

r = 39

Therefore, the radius r for the circle C is equal to 39 using the Pythagoras rule for the right triangle ABC.

2. Suppose a consumer has $30 available to be divided between commodities A and B and the unit price of B is fixed at $3. What will be his demand equation for A if his utility function is U = 4XgXb?​

Answers

The demand equation for commodity A is Xa = (4/10)Xb.

What is demand equation?

A demand equation is a mathematical representation of the relationship between the quantity of a good or service that consumers are willing to buy and the various factors that influence that demand, such as price, income, and preferences.

In the given question,

To find the consumer's demand equation for A, we need to use the utility maximization rule, which states that a consumer will allocate their budget in such a way as to maximize their total utility subject to their budget constraint.

Let Xa be the quantity of commodity A and Xb be the quantity of commodity B. We know that the consumer has $30 to spend, so the budget constraint is:

3Xb + pXa = 30

where p is the price of commodity A. We also know the utility function:

U = 4XgXb

To maximize U subject to the budget constraint, we can use the Lagrangian method:

L = 4XgXb + λ(30 - 3Xb - pXa)

where λ is the Lagrange multiplier.

To find the demand equation for A, we need to take the partial derivative of L with respect to Xa and set it equal to zero:

∂L/∂Xa = -λp = 0

This gives us λ = 0, which we can substitute back into the Lagrangian equation to get:

L = 4XgXb + 0(30 - 3Xb - pXa)

L = 4XgXb

To find the demand equation for A, we need to take the partial derivative of L with respect to p and solve for Xa:

∂L/∂p = -4XgXb/Xa = -30/3

Xa = (4/10)Xb

So the demand equation for commodity A is Xa = (4/10)Xb.

Answers

A 90 degree clockwise rotation about the point (0,0), the new coordinates of Point B are (3, -1) and the new coordinates of Point C are (1, -2).

How do you check if a quadrilateral is a rectangle on a graph?

A quadrilateral can be proven to be a rectangle in a number different ways. Here are the three simplest methods: 1. Establish that all angles are 90 degrees; 2. Establish that two opposed angles are 90 degrees; and 3. Establish that the diagonals are equally long and intersect one another.

The following transformation matrix can be used to rotate a point (x,y) 90 degrees clockwise with respect to the origin (0,0):

|0 1|\s|-1 0|

This transformation matrix can be applied to each point to determine its new coordinates upon rotation.

Point B is the first point, and its initial coordinates are (-1, 3). The transformation matrix in use:

|0 1| |-1| |3|

|-1 0| x |3| = |-1|

After rotating Point B 90 degrees clockwise, the new coordinates are: (3, -1).

The transformation matrix is then applied to Point C, whose initial coordinates are (2, 1):

|0 1| |2| |1|

|-1 0| x |1| = |-2|

After rotating in a clockwise direction by 90 degrees, Point C's new coordinates are (1, -2).

As a result, after rotating 90 degrees in a clockwise direction around Point 0, Point B's new coordinates are (3, -1), while Point C's new coordinates are (1, -2).

To find the area of the total figure, we need to first find the areas of the rectangle and triangle, and then add them together.Therefore, the area of the total figure is 200 square feet.

What is area?

Area is the measurement of the size of a two-dimensional surface enclosed by a closed figure

Area of rectangle = length x width

= 20 ft x 8 ft

= 160 sq. ft

Area of triangle = 1/2 xbase xheight

= 1/2 x 8 ft x 10 ft

= 40 sq. ft

To find the base of the triangle, we can use the Pythagorean theorem, which states that the square of the hypotenuse (slope) of a right triangle is equal to the sum of the squares of its two sides. In this case, the hypotenuse is 12 ft, one of the other sides is the height of the triangle (10 ft), and the other side is the base of the triangle (b).

Using the Pythagorean theorem, we have:

12² = 10² + b²

144 = 100 + b²

44 = b²

b = √44

b ≈ 6.63 ft

Now that we know the base of the triangle, we can find the area of the total figure by adding the area of the rectangle and the area of the triangle:

Area of total figure = area of rectangle + area of triangle

= 160 sq. ft + 40 sq. ft

Answers

(a) The p-value = 0.017 (b)  the conditions are met to conduct the test. (c) the correct conclusion is: Reject the null hypothesis

How to find the The p-value and if the conditions met to conduct this test

(a) Using the given data, we can calculate the test statistic z-score as:

z = (xbar - μ) / (σ / sqrt(n))

= (1138 - 1000) / (605 / sqrt(42))

= 2.378

Using StatCrunch, the p-value for a two-tailed test with a test statistic of 2.378 and degrees of freedom of 41 (n - 1) is 0.017.

Therefore, the p-value = 0.017 (to 3 decimal places).

(b) To conduct a hypothesis test for a population mean, we need to check if the following conditions are met:

The population is approximately normal or the sample size is large (n ≥ 30).

The population standard deviation (σ) is unknown.

Here, n = 42 which is greater than 30, so we can assume that the population is approximately normal. The standard deviation of the population is unknown.

Therefore, the conditions are met to conduct the test.

(c) The null and alternative hypotheses are:

Null hypothesis (H0): The mean wastewater discharged by the industrial plant is 1000 gallons per hour (μ = 1000).

Alternative hypothesis (Ha): The mean wastewater discharged by the industrial plant exceeds 1000 gallons per hour (μ > 1000).

At alpha = 0.05 (5% level of significance), the critical z-value for a one-tailed test is 1.645.

Since the calculated z-score (2.378) is greater than the critical value (1.645), we reject the null hypothesis.

Therefore, the correct conclusion is: Reject the null hypothesis. There is sufficient evidence that the wastewater discharged by the industrial plant exceeds 1000 gallons per hour.
