how do you find the smallest positive integer k such that 1350k is a perfect cube?
The smallest positive integer k such that 1350k is a perfect cube is found by prime factorizing 1350 and ensuring that all prime exponents in its factorization are multiples of 3. The missing exponents for 2 and 5 are 2 and 1 respectively, so multiplying by k=20 achieves this.
Explanation:To find the smallest positive integer k such that 1350k is a perfect cube, we start by factoring 1350 into its prime factors. We have 1350 = 2 × 3^3 × 5^2. In order for a number to be a perfect cube, all the exponents in its prime factorization must be multiples of 3 since a cube of any number is that number multiplied by itself three times. In the prime factorization of 1350, the exponent of 2 is 1 (which is 2 short of a multiple of 3) and the exponent of 5 is 2 (which is 1 short of a multiple of 3).
To make the number a perfect cube, we need to multiply it by a k such that the prime factorization of the result has all exponents as multiples of 3. Therefore, we need one more 2 to make the exponent of 2 equal to 3, and we need one more 5^1 to make the exponent of 5 equal to 3. This gives us a k of 2^2 × 5^1 = 4 × 5 = 20. So, k=20 is the smallest positive integer that, when multiplied by 1350, results in a perfect cube.

What is the slope of the line whoes equation is 2x-4y=10
The slope of the line is 12.
The equation of a line in slope-intercept form is y=mx+b, where m is the slope, is the y-intercept, and x and y are a point on the line.
In order to determine the slope from the given equation do the following:
2x−4y=10 (Subtract 2x from both sides.)
−4y=−2x+10 (Divide both sides by -4.)
y=−2x−4+10−4 (Simplify.)
y=12x−52

Please help on the following two questions. Explain your reasoning.
1) Every time a football team makes a touchdown worth 6 points, it is given the opportunity to make an extra point. So far in a game, it has made t touchdowns and scored a total of 7t - 6 points. If touchdowns and extra points are the only way it has scored, what does the 6 represent?
A. the number of extra points attempted
B. the number of extra points made
C. the number of extra points missed
D. the number of touchdowns made
2) Jacob stated that he solved the equation 2x + 3 = 5 using the addition property and multiplication property of equality. Which statement is true?
A. Jacob added -3 to both sides and multiplied both sides by 1/2.
B. Jacob added -3 to both sides and multiplied both sides but 2.
C. Jacob added 3 to both sides and multiplied both sides but 1/2.
D. Jacob added 3 to both sides and multiplied both sides but 2.
In the scoring question, 6 represents the missed extra points. For the second question, Jacob initially subtracted 3 from both sides of the equation, then he multiplied both sides by 1/2 to solve for x.
Explanation:1.) Given the equation for the total score of the football team, 7t - 6, where t represents the number of touchdowns. Each touchdown is worth 7 points (6 points for the touchdown and a possible extra 1 point). If the total score is 7t - 6, then the 6 in the equation represents the number of extra points missed. So the correct answer is C.
2.) As for Jacob's method on solving the equation 2x + 3 = 5, he should first isolate the term with x by using the addition property of equality, subtracting 3 from both sides.
This changes the equation to 2x = 2. Afterwards, he can use the multiplication property of equality by multiplying both sides by 1/2 to solve for x.
Therefore, it sounds like Jacob added -3 to both sides and multiplied both sides by 1/2, which makes the correct answer A.

The longest side of an isosceles obtuse triangle measures 20 centimeters. The other two side lengths are congruent but unknown.
What is the greatest possible whole-number value of the congruent side lengths?
A.9 cm
B.10 cm
C.14 cm
D.15 cm
Answer:
C. 14 cm
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of any two sides of a triangle must be greater than the measure of the third side.
Given,
The longest side of an isosceles obtuse triangle measures 20 centimeters.
Let x be the measure of the other two congruent sides,
By the above property,
20 < x + x
20 < 2x
10 < x
Thus, the measure of congruent sides must be greater than 10 cm,
Now, In an isosceles obtuse triangle, the square of the longest side is greater than the sum of squares of the other two congruent sides.
[tex](20)^2>x^2+x^2[/tex]
[tex]400>2x^2[/tex]
[tex]200>x^2[/tex]
[tex]10\sqrt{2}>x[/tex]
Since, √2 = 1.41421356≈ 1.41
[tex]\implies x < 10\times 1.41\implies x < 14.1[/tex]
Hence, the greatest possible whole-number value of the congruent side lengths is 14.
Option C is correct.

Micheal walks 30 meters in 20 seconds. How many meters does he walk per second?
To calculate how many meters Micheal walks per second, we divide the distance he walks (30 meters) by the time (20 seconds), resulting in a walking speed of 1.5 meters per second.
Explanation:The question asks us to calculate how many meters Micheal walks per second, given that he walks 30 meters in 20 seconds. To find this, we use the formula for speed, which is the distance traveled divided by the time taken. Here, the distance is 30 meters and the time is 20 seconds.
Thus, the speed (meters per second) is calculated as follows:
Divide the total distance by the total time: 30 meters ÷ 20 seconds = 1.5 meters per second.Therefore, Micheal walks at a speed of 1.5 meters per second.
You earn $10.00 per hour babysitting. Your total earnings depend on the number of hours you spend babysitting.
Susan's total income remains $16,000 regardless of the number of hours she works, up to the point where her earnings from work alone would exceed her government benefits. This design of the assistance program potentially reduces her incentive to work more hours. Opportunity costs must also be factored in, which can further influence her decisions.
Explanation:Creating Susan's Income Table
Susan has the option to work up to 1,800 hours a year at $8 per hour. If Susan does not earn any income, she is entitled to $16,000 in government benefits. However, for every dollar she earns, her government support reduces by the same amount. To understand Susan's situation better, we can create a table showing various scenarios.
Let's assume Susan decides to work 500 hours in a year:
If Susan works more, her earnings increase but her benefits decrease, keeping her total income stagnant at $16,000, until she surpasses the threshold of $16,000 in earnings. This suggests the assistance program may limit her incentive to work more hours as the additional work does not increase her total income. Moreover, Susan must consider opportunity costs, such as childcare expenses, that might further reduce her incentive to work additional hours.
The Impact of Government Assistance on Work Incentives
Opportunity costs play a crucial role in Susan's decision-making. If the costs of working (like paying for childcare) exceed the benefits of working additional hours, she might opt to work less or not at all. Therefore, assistance programs can impact individual's work choices by affecting the marginal benefit of working additional hours.

How to compare two quantities?If 3 miles = 2 hours
For 4 miles the number of hours is:
3 miles = 2 hours
4/3 x 3 miles = 4/3 x 2 hours
4 miles = 8/3 hours
We have,
Justin:
Justin weighs 150 lb and hopes to gain 2 lb per week.
Let the number of weeks be W.
We can write the weight of Justin after W weeks as:
150 + 2W _____(1)
Tyson :
Tyson weighs 195 lb and hopes to lose 1 lb per week.
Let the number of weeks be W.
We can write the weight of Tyson after W weeks as:
195 - 1W _____(2)
Now,
The number of weeks both weighs the same:
From (1) and (2)
150 +2W = 195 - 1W
2W + 1W = 195 - 150
3W = 45
W = 45/3
W = 15
We can see that,
From (1) and (2)
150 + 2W = 150 + 2 x 15 = 150 + 30 = 180
195 - 1W = 195 - 1 x 15 = 195 - 15 = 180
Thus the number of weeks will the boys weigh the same amount is 15 weeks and the weight is 180 lb.
