Raju went to a shop and bought 4 books at the rate of Rs 222.75 each, and 2 books are sold at Rs. 14 each.​

Answer:

7m + 20 ≥ 150

Closest option is 7m + 20 > 150 which is the second choice

Step-by-step explanation:

The words "at least" indicate a ≥ inequality.

There is a fixed earning of $20 for entering the race. So this amount will be earned on regardless of how much Carol runs

For each mile she runs she earns $7. For running m miles, she earns 7m dollars

Total amount earned for running m miles = 7m + 20
This must be at least $150
So the correct inequality is
7m + 20 ≥ 150

I don't see this exact inequality in any of the answer choices but that is the correct answer.

The value of m if the ratio of their heights is equal to 1:m is 4/3.

Ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that;

Area of A=144cm²

Area of B=256cm²

Ratio of heights= 1:m

Now,

The ratio of the areas of two similar solids is equal to the square of the ratio of their corresponding heights. So, we have:

(area of A) / (area of B) = (height of A)^2 / (height of B)^2

Substituting the given values, we get:

144 / 256 = 1^2 / m^2

9 / 16 = 1 / m^2

Multiplying both sides by m^2, we get:

9m^2 / 16 = 1

Multiplying both sides by 16/9, we get:

m^2 = 16/9

Taking the square root of both sides (and noting that m must be positive since it is a length), we get:

m = 4/3

Therefore, by the given ratio answer will be 4/3.

As a result, for purchases of $9500, the salesperson gets a royalty of $285.

Commission, also known as a sales bonus, is paid to employees in accordance with the amount of sales they make. Statement generation is offered without charge by SumUp Bills. Frequently, a fee is calculated as a percentage of the sale's value.

To find the commission that the salesperson receives for $9500 in sales, we can use the formula:

commission = rate x sales

where rate is the commission rate as a decimal, and sales is the amount of sales.

In this case, the rate is 3% or 0.03, and the sales is $9500.When these numbers are added to the algorithm, we obtain:

commission = 0.03 x $9500

Simplifying this expression, we get:

commission = $285

Therefore, the salesperson receives a commission of $285 for $9500 in sales.

The highest spot on the ball's trajectory, which is at the vertex of the parabolic path, must be identified in order to calculate the maximum height the ball has ever attained.

The following equation describes the height of the projectile as a function of time:

s = -16t² + 64t

We can apply the following method to determine the parabola's vertex:

t = -b/2a

where b = 64 and a = -16.

By replacing these numbers, we obtain:

t = -64/(2*(-16)) = 2

Thus, after two seconds, the utmost height is reached.

We can enter t = 2 into the calculation to get the height at this point:

s = -16(2)² + 64(2) = 64 feet

The height of the trapezoid is h = 4, and the answer is B.

A trapezoid, also known as a trapezium, is a four-sided polygon with two parallel sides, also called the bases. The non-parallel sides are called legs, and they can have different lengths. The parallel sides are perpendicular to the legs.

There are two types of trapezoids:

Isosceles trapezoid: This type of trapezoid has two parallel sides of equal length and two legs of equal length.

Scalene trapezoid: This type of trapezoid has two parallel sides of different lengths and two legs of different lengths.

We can use the formula A = 1/2 * h * (b1 + b2) to solve for h. Substituting the given values, we get:

28 = 1/2 * h * (6 + 8)

28 = 1/2 * h * 14

28 = 7h

If to display charts and other educational material, your teacher has requested that two rows of strips be placed around the entire room. the total length of strips is: 4L + 4W.

To find the total length of strips required, we need to know the dimensions of the room. Let's assume that the room has a length of L and a width of W.

If we place two rows of strips around the entire room, one at the top and one at the bottom, the length of each strip will be equal to the perimeter of the room.

The perimeter of the room can be calculated as:

P = 2L + 2W

So, the length of strips required for one row around the room will be:

L1 = P = 2L + 2W

Since we need two rows of strips, the total length of strips required will be:

L2 = 2L1 = 2(2L + 2W) = 4L + 4W

Let's use the following variables to represent the unknowns:

From the problem, we can write the following system of equations:

x + y + z = 7 (total number of sections)

40x + 40y + 10z = 220 (total number of students)

40000x + 60000y + 29000z = 298000 (total revenue)

Simplify

x + y + z = 7

4x + 4y + z = 220

40x + 60y + 29z = 298

We can solve this system of equations using substitution

So, we have

x = 7 - y - z

By substitution, we have

4(7 - y - z) + 4y + z = 22

This gives

28 - 4y - 4z + 4y + z = 22

So, we have

28 - 3z = 22

This gives

3z = 6

Divide

z = 2

Recall that

40x + 60y + 29z = 298

So, we have

40x + 60y + 29*2 = 298

40x + 60y + 58 = 298

This gives

40x + 60y = 240

Divide by 20

2x + 3y = 12

Also, recall that x = 7 - y - z

So, we have

2(7 - y - z) + 3y = 12

This gives

2(7 - y - 2) + 3y = 12

2(5 - y) + 3y = 12

Open brackets

10 - 2y + 3y = 12

Evaluating the like terms, we have

To find the total surface area that Lisa will need to paint purple, we need to first calculate the surface area of each piece of wood and then add them together.

The longer piece of wood has a surface area of:

2 x 7 = 14 square inches on one side

2 x 2 = 4 square inches on the other side

2 x 5 = 10 square inches on the third side

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The problem asks us to construct a boxplot and identify the 5-number summary of a set of data. The data represents the amounts of strontium-90 (in millibecquerels, or mBq) in a sample of baby teeth from residents born after 1979. The data is as follows:

124, 127, 131, 135, 138, 142, 142, 143, 147, 150, 154, 156, 157, 160, 163, 168, 170, 171, 174, 181

To construct the boxplot, we need to first find the 5-number summary, which consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. We can find these values by putting the data in ascending order and then using the following formulas:

Q1 = median of the lower half of the data

Q2 = median of the entire data set

Q3 = median of the upper half of the data

Using these formulas, we find the 5-number summary to be:

Minimum value: 124 mBq

Q1: 138 mBq

Median: 150 mBq

Q3: 168 mBq

Maximum value: 181 mBq

We can now use this information to construct the boxplot. The horizontal axis represents the values in the data set, and the vertical axis represents the frequency or density of those values. The boxplot consists of a box that extends from Q1 to Q3, with a line segment drawn through the box at the median (Q2). Whiskers extend from the top and bottom of the box to the minimum and maximum values, respectively, unless there are outliers. Outliers are plotted as individual points beyond the whiskers.

Therefore, In this case, the boxplot is option A, which shows the box extending from 130 to 165.5 mBq, with a line segment drawn through the box at 160.75 mBq. The whiskers extend from 114 to 201 mBq, with no outliers.

What is expressions ?

Expressions can be simplified, evaluated, or manipulated using mathematical rules and operations. They are used in a variety of mathematical contexts, such as algebra, geometry, calculus, and more.

We can start by finding the rate of temperature increase per minute. Since the temperature rose 3 degrees in 1/6 of a minute, we can multiply both sides by 6 to find the rate per minute:

3 degrees ÷ (1/6 minute) = 18 degrees per minute

So the oven heats up at a rate of 18 degrees per minute. To find how much the oven will heat up in 1 minute, we simply multiply the rate by the time:
