Answer:

Here is how to write and graph an inequality for the budget problem:

Let x be the number of large boxes and y be the number of small boxes. The total cost of the boxes must be less than or equal to the budget of $500. So, we can write the inequality as:

65x + 35y ≤ 500

To graph this inequality, we need to find the boundary line and the shaded region. The boundary line is the equation that we get when we replace the inequality sign with an equal sign, which is:

65x + 35y = 500

To graph this line, we need to find two points on it. We can do this by plugging in some values for x or y and solving for the other variable. For example, if x = 0, then y = 500/35 = 14.29. If y = 0, then x = 500/65 = 7.69. So, two points on the line are (0, 14.29) and (7.69, 0). We can plot these points on a coordinate plane and draw a solid line through them, since the inequality includes the equal sign.

To find the shaded region, we need to test a point that is not on the line and see if it satisfies the inequality. For example, we can test the point (0, 0), which is the origin. Plugging in x = 0 and y = 0 into the inequality, we get:

65(0) + 35(0) ≤ 500

0 ≤ 500

This is true, so the point (0, 0) is a solution to the inequality. This means that the shaded region is the area that includes the point (0, 0) and is below the line.

If Renaldo buys 6 small gift boxes, then y = 6. To find how many large gift boxes he can afford, we need to plug in y = 6 into the inequality and solve for x. We get:

65x + 35(6) ≤ 500

65x + 210 ≤ 500

65x ≤ 290

x ≤ 290/65

x ≤ 4.46

This means that Renaldo can buy at most 4 large gift boxes if he buys 6 small gift boxes. However, since x has to be a whole number, the largest possible value for x is 4. So, Renaldo can buy 4 large gift boxes and 6 small gift boxes and still stay within his budget.

I hope this helps!

The number of hours you have to wait is 300 minutes.

What is the unit rate?

A unit rate is a cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

Given that,

You are told to you will have to wait 5 hours in a line with a group of other people.

For someone earning $75,000 per year working 24 hours daily, their equivalent hourly wage would be approximately $8.56 per hour.

If someone worked 24 hours a day, every day of the year, they would work a total of 8,760 hours in a year. To calculate the hourly wage of someone earning $75,000 per year working 24 hours daily, you can divide the yearly salary by the total number of hours worked in a year.

Dividing $75,000 by 8,760 hours gives an hourly wage of approximately $8.56. This means that if someone earned $75,000 per year while working 24 hours a day, they would be earning an equivalent of approximately $8.56 per hour.

Answer:

Area is approximately 113.1

The height of the silo is approximately 81 meters to the nearest meter.

One of the most basic areas of mathematics, trigonometry has a wide range of applications. The study of the relationship between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry."

Let's draw a diagram to visualize the situation. We have a right triangle with the transit (T), the silo (S), and a point on the ground (G) where the surveyor is standing. The angle of elevation of the silo from the surveyor's position is 52º, and we know the distance TG = 65 m and the height of the transit HT = 1.7 m. We want to find the height of the silo, which is HS.

          S

          | \

    HS |  \  TG = 65 m

          |   \

          |      \

          |       \

          |        \

          T--------G

             HT = 1.7 m

Using trigonometry, we have the following equation:

tan(52º) = HS / TG + HT

Solving for HS, we get:

HS = (TG + HT) * tan(52º)

= (65 + 1.7) * tan(52º)

≈ 81.1 m

Therefore, the height of the silo is approximately 81 meters to the nearest meter.

The value of the residual for Shawna's weight and height is 12.4 and option 2 is the correct answer.

A linear equation is one that has the form Ax+By=C. This definition comes from mathematics. It consists of two variables combined with a constant value that exists in each of them.

The collection of all values that, when substituted for unknowns, cause an equation to hold true is known as the solution. Two fundamental algebraic rules using the additive property and the multiplicative property are utilised to determine the solutions for equations needing a single unknown raised to a power of one.

The equation given to predict the weight from height is:

ŷ = -260 + 6.6x

Given that, Shawna’s height was 64 inches.

Substituting the value in x we have:

ŷ = -260 + 6.6x

ŷ = -260 + 6.6(64)

ŷ = 162.4

The actual weight is given as 150 pounds.

The residual value of the weight from the predicted formula is:

r = 162.4 - 150

r = 12.4

Hence, the value of the residual for Shawna's weight and height is 12.4 and option 2 is the correct answer.

Answer:

The correct answer is B. 60 and 64. When y is directly proportional to x, it means that the ratio of y to x remains constant. In this case, when x=6, y=36, which means that the ratio of y to x is 36/6. Since the ratio is constant, we can use that ratio to find the values of y when x=8 and x=10. When x=8, y = (36/6)x8 = 60 and when x=10, y = (36/6)x10 = 64.

In mathematics, conversion is the process of changing a value from one form to another, such as converting a value from inches to millimeters, for time minutes to hours, or other units.

How to convert centimeters to feet : 1 meter is a measure of length and equals approximately 3.28 feet.

152 meters = 152×3.28 feet = 498.56 feet --(1)

But we need to convert 152 centimeters to feet. So change meters to centimeters. As you know, 1 meter is 100 centimeters, so 152 meters = 15200 centimeters --(2). Now from equations (1) and (2),

The measurement of 1.72 metres into feet may be determined using the same conversion factor.
