What is the inequality for this verbal description?Sam has d dollars to spend on grapes and carrots. He wants to buy one bag of grapes for $4.00 and c pounds of carrots that cost $2.00 per pound. Which inequality represents this situation?
Final answer:
The inequality for Sam's expenditures on grapes and carrots, with grapes costing $4 and carrots costing $2 per pound, is 4 + 2c <= d.
Explanation:
The inequality that represents Sam's spending on grapes and carrots, given that he has d dollars to spend, is 4 + 2c ≤ d. This inequality is derived from the cost of one bag of grapes, which is $4, and the cost of carrots, which is $2 per pound. The variable c represents the number of pounds of carrots Sam wants to buy. The total cost of grapes and carrots must be less than or equal to the amount of money Sam has, which is d dollars.

Atrap and Bracken are two rival insurance companies. Atrap and Bracken have premiums of $150 and $100 and deductibles of $2,500 and $3,500 respectively. The average expense of surgery is $25,000. If after 5 years, 25 of the 1,000 people registered with Bracken have gone through surgery, where does Bracken stand in terms of gains or losses?
Answer:
Bracken has incurred a loss of $37,500
Step-by-step explanation:
People who have registered with Bracken insurance company pays premium of $100. 1,000 people in total have registered with Bracken. In 5 years Bracken would have earned an income of $500,000 [tex]\left ( $100\times1,000\times5)\right[/tex].
25 among the 1,000 registered have undergone surgery. Average surgery expense is $25,000. $3,500 is deductible. So Bracken's total expense per client is $21,500 (25,000 - 3,500). For 25 patients, it will be $537,500 [tex]($21,500\times25)[/tex].
Since expenses of $537,500 is more than income of $500,000, Bracken incurs a loss of $37,500 (500,000 - 537,500) over 5 years.
Therefore, Bracken's loss over 5 years is $37,500

MpRashawn recently spent $100 to open a store selling tee-shirts. At his business, he purchases plain tee-shirts for $11 each, prints graphics on them, and then sells them for $26 each. What is the minimum number of tee-shirts that Rashawn would need to sell in order to make a profit (total income minus total expenses) of at least $400?
Rashawn would need to sell 20 T-Shirts in order to make a profit of at least $400.
What is profit percentage?SP-CP divided by CP multiplying with 100 we get profit percentage.
P= [(SP-CP)/CP ] × 100
Given the following details about Mr. Rashawn.
Mr. Rashawn recently spent = $100 to open a store selling tee-shirts
He purchases plain tee-shirts for = $11 each
Then sells them for = $26 each
Profit on each shirt = $26 - $11 = $15
Profit = $400 -$100= $ 300
Number of t- shirts= $300/15 = 20 T -shirts.
Thus, Rashawn would need to sell 20 T-Shirts in order to make a profit of at least $400.

A cross-section of a light reflector is a parabola. The bulb is located at the focus. Suppose the bulb is located 11 in from the vertex of the reflector.
Use this information to make the following determinations.
Model a cross section of the reflector by writing an equation of a parabola that opens upward and has its vertex at the origin.
An equation of a parabola that opens upward and has its vertex at the origin,
⇒ y² = - 8 x
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Now,
The equation of the parabola turned to the left is to the negative side of the coordinate system is:
⇒ y² = - 2 p x
where, p is the parameter of the parabola
The relationship between the parameter and the focus is.
⇒ p = 2 f
=> p = 2 × 2
⇒ p = 4 cm
Then, the equation of the parabola is:
y² = - 2 p x
= - 2 × 4 x
= - 8 x
Therefore, An equation of a parabola that opens upward and has its vertex at the origin,
⇒ y² = - 8 x

Write an equation to solve each problem and then solve it. There are two numbers whose sum is 53. Three times the smaller number is equal to 19 more than the larger number. What are the numbers?
In RST , RS=11 ,RT=9 and ST=6 which angle of RST has the smallest measure ?
<R angle of RST has the smallest measure.
The correct option is C.
We have,
RS=11 ,RT=9 and ST=6
Now, from the given lengths it can be seen that the length of ST is shortest and length of RS is longest.
By the definition which states that,
The angle opposite to longest side is largest and the angle oppsite to shortest side is smallest.
From given, <R is opposite to shortest side ST.
Thus, the smallest angle is R.

Sergio runs 2 1/4 miles in 30 minutes. Write the ratio in fractional form and determine Sergio's speed in miles per hour.
Sergio runs at a speed of 4.5 miles per hour. The ratio of his running distance to time is 9/2.
Explanation:To determine Sergio's speed in miles per hour (mph), we use the equation: speed = distance/time. Sergio runs 2 1/4 miles in 30 minutes. First, we need to convert the fractional distance to a decimal and the time to hours. 2 1/4 miles is equal to 2.25 miles and 30 minutes is equal to 0.5 hours.
Substitute these values into the equation:
speed = 2.25 miles/0.5 hour = 4.5 mph.
Therefore, Sergio's running speed is 4.5 miles per hour. The ratio of distance to time in fractional form would be 9/2.

The American flag is customarily made with its width and length in the ratio of 10 to 19. Which of the following dimensions is in the correct ratio for the flag?
Final answer:
The given dimensions do not match the American flag's customary ratio of 10 to 19. To find the correct dimensions, the numbers must divide to equal approximately 0.5263. None of the provided options are correct.
Explanation:
The American flag is customarily made with its width and length in the ratio of 10 to 19. To ensure the dimensions are correct, we must find a pair of numbers that, when divided, are in the same proportion as 10/19 (approximately 0.5263). Looking at the listed dimensions:
51 H (Height is not a width or length measurement, so we cannot confirm the ratio)
53 x 38 (53/38 = 1.3947 which is not equal to 10/19)
55 x 0.025 (55/0.025 = 2200 which is not equal to 10/19)
57 x (2.93, 3.59) (This does not provide a pair of length and width measurements)
59 (This is not a dimension)
Since none of the provided options has numbers that mirror the 10 to 19 ratio of the flag, none of these dimensions would be correct for an American flag. If we want to find dimensions that are proportional, we have to look for any two numbers that, when divided, equal approximately 0.5263. Hence, an example of a correct dimension following the flag's ratio would be 10 inches by 19 inches or any multiple thereof.

In the linear equation y = 2x + 1, if x increases by 4 points, how much will y increase?
If [tex]\(x\)[/tex] increases by 4 points, [tex]\(y\)[/tex] will increase by 8 units.
In the linear equation [tex]\(y = 2x + 1\)[/tex], the coefficient of [tex]\(x\)[/tex] is 2. This means that the slope of the line is 2, and for every one unit increase in [tex]\(x\), \(y\)[/tex] will increase by 2 units.
Given that [tex]\(x\)[/tex] increases by 4 points, the corresponding increase in [tex]\(y\)[/tex] can be found by multiplying the change in [tex]\(x\)[/tex] by the slope:
[tex]\[\Delta y = \text{Slope} \times \Delta x\][/tex]
[tex]\[ \Delta y = 2 \times 4 = 8\][/tex]
Therefore, if [tex]\(x\)[/tex] increases by 4 points, [tex]\(y\)[/tex] will increase by 8 units.
Example:
Let's use the given linear equation [tex]\(y = 2x + 1\)[/tex] and demonstrate how an increase in [tex]\(x\)[/tex] by 4 points results in an increase in [tex]\(y\)[/tex] by 8 units.
Given Linear Equation:
[tex]\[y = 2x + 1\][/tex]
Let's consider an initial point on the line where [tex]\(x = 3\)[/tex]. Find the corresponding [tex]\(y\)[/tex]:
[tex]\[y = 2(3) + 1 = 7\][/tex]
So, when [tex]\(x = 3\), \(y = 7\)[/tex].
Now, if [tex]\(x\)[/tex] increases by 4 points, new [tex]\(x\)[/tex] value will be [tex]\(3 + 4 = 7\)[/tex].
Using the same linear equation to find the new [tex]\(y\)[/tex]:
[tex]\[y_{\text{new}} = 2(7) + 1 = 15\][/tex]
Now, calculate the increase in [tex]\(y\)[/tex]:
[tex]\[\Delta y = y_{\text{new}} - y_{\text{initial}} = 15 - 7 = 8\][/tex]
So, in this example, when [tex]\(x\)[/tex] increases by 4 points (from 3 to 7), [tex]\(y\)[/tex] increases by 8 units (from 7 to 15), confirming that the increase in [tex]\(y\)[/tex] is proportional to the increase in [tex]\(x\)[/tex] with a slope of 2.
