The price of the basketball on sale is $17.50.
To calculate this:
1. Calculate 50% of $35:
$35 x 0.50 = $17.50
2. Subtract the discount from the original price:
$35 - $17.50 = $17.50
When an item is on sale for a percentage off, you first find what that percentage represents of the original price. In this case, 50% of $35 is $17.50. Then, you subtract that amount from the original price to find the sale price. So, the basketball, originally priced at $35, would be $17.50 when it's on sale for 50% off.
Complete question:
Find the price of a $35 basketball that is on sale for 50% off the regular price.

Use the formula for interest. P= $250 r= 7.2% Y= 15 A= ?
Answer:
value of A is $520
Step-by-step explanation:
Calculate the amount 'A' by using formula:-
A = P ( 1 + r * Y )
Where A is amount, P is principle , r is rate of interest and Y is time in years
Now, put the given values in A = P ( 1 + r * Y ) to get the value of A.
Since, P= $250, r= 7.2% and Y= 15
r = 7.2% so r = 0.072
A = P ( 1 + r * Y )
A = $250 ( 1 +0.072 * 15 )
A = $250 ( 1 + 1.08 )
A = $250 ( 2.08 )
A = $520
Hence, value of A is $520
The top of a 15-foot ladder leans against a wall, and the bottom of the ladder slides away from the wall at a rate of 4 ft/sec. find the velocity of the top of the ladder at time t = 1 sec if the bottom of the ladder is 5 feet away from the wall at time t = 0.
Final answer:
The velocity of the top of the ladder at time t = 1 sec is -4 ft/sec.
Explanation:
To find the velocity of the top of the ladder at time t = 1 sec, we can use the concept of similar triangles. Let x be the distance between the bottom of the ladder and the wall at time t = 1 sec. Since the bottom of the ladder slides away from the wall at a rate of 4 ft/sec, we have x = 5 + 4t.
The height of the ladder remains constant at 15 ft, so if we consider the triangle formed by the ladder, the wall, and the ground, we have the ratio of the height to the base is always 15 / x. Therefore, the velocity of the top of the ladder can be found by taking the derivative of the height with respect to time.
Let h be the height of the ladder at time t. Since h = 15, we have 15 / x = 15 / (5 + 4t). Taking the derivative of both sides, we get d/dt (15 / x) = d/dt (15 / (5 + 4t)). Using the quotient rule, we have d/dt (15 / x) = (0 - 15)(0 - (5 + 4t)-2)(4) = -60 / (5 + 4t)². This gives us the velocity of the top of the ladder at time t = 1 sec: v = -60 / (5 + 4(1))² = -4 ft/sec.
a rectangle is 4 centimeters longer than it is wide. the area is 117 square centimeters. find the dimensions of the rectangle
Answer:
width: 9 cmlength: 13 cmStep-by-step explanation:
Integer factors of 117 include ...
... 117 = 1×117 = 3×39 ≈ 9×13
The last factor pair is two factors that differ by 4. We can take these to be the dimensions of the rectangle.
_____
If you want to write an equation for width (w), it might be ...
... w(w+4) = 117
... w² +4w -117 = 0
The factorization problem for this quadratic is the problem of finding two factors of 117 that differ by 4. That is what we have done, above.
If you want to solve this by completing the square, you can to this:
... w² +4w = 117
... w² +4w +4 = 121 . . . . . add 4 = (4/2)² to complete the square
... (w+2)² = 121
... w + 2 = ±√121 = ±11 . . . . take the square root
... w = -2 ± 11 . . . . . we're only interested in the positive solution
... w = 9, then w+4 = 13 and the dimensions are 9 cm by 13 cm.

An equation that represents the set of points that are 2 units from (-2,-6)
The equation representing the set of points that are 2 units from the point (-2,-6) is a circle with equation (x + 2)^2 + (y + 6)^2 = 4
The question asks for an equation that represents the set of points that are exactly 2 units from the point (-2,-6) in a coordinate system. This set of points forms a circle with a radius of 2 units centered at (-2,-6). The equation for a circle with radius r and center (h, k) is (x - h)² + (y - k)² = r². Thus, the equation of the circle is (x + 2)² + (y + 6)² = 2² or (x + 2)² + (y + 6)² = 4

10x + 16 ≥ 6x + 20 what is the answer to this
Answer:
The solution of given inequality is x ≥1.
Step-by-step explanation:
The given inequality is
[tex]10x+16\geq 6x+20[/tex]
We need to separate the variable terms to solve the above inequality.
Subtract 6x and 16 from both sides to separate the variables on left side.

Find the work done by the force field f(x, y, z) = x − y2, y − z2, z − x2 on a particle that moves along the line segment from (0, 0, 1) to (3, 1, 0).
The work done by force field on a particle moving from one point to another in space is calculated using the concept of dot-product. The force field is represented as a function and the movement of the particle is treated as a path. By integrating the dot product of the force field and the derivative of path over the interval, we get the work done.
Explanation:To calculate the work done by force field on a particle, you need to apply the concept of dot product in vector calculus. The force field is defined as f(x, y, z) = x − y², y - z², z - x² and the movement of the particle is from (0, 0, 1) to (3, 1, 0). We treat this movement as a line segment in the 3-dimensional space.
The work done by the force field on the particle is calculated as W = F . dr = ∫ F(r(t)) . r'(t) dt from t1 to t2. In this case, the force field F is f(x, y, z) and the line segment can be treated as a path r(t) = t * (3, 1, 0) + (1 - t) * (0, 0, 1) and t varies from 0 to 1. Hence, r'(t) = (3, 1, 0) - (0, 0, 1).

The manager of a store that specializes in selling tea decides to experiment with a new blend. She will mix some Earl Grey tea that sells for $ 6$6 per pound with some Orange Pekoe tea that sells for $ 4$4 per pound to get 600600 pounds of the new blend. The selling price of the new blend is to be $ 4.50$4.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types. How many pounds of the Earl Grey tea and Orange Pekoe tea are required?
To find the quantities of Earl Grey and Orange Pekoe tea needed to make a 600-pound blend that sells for $4.50 per pound, we use the mixture price formula, leading to a linear equation representing the total cost of blending these teas.
Explanation:The manager wants to blend Earl Grey tea ($6 per pound) and Orange Pekoe tea ($4 per pound) to produce 600 pounds of a new blend selling for $4.50 per pound without affecting revenue. To determine the required pounds of each tea, we can use the mixture price formula: total cost = (quantity of Earl Grey × price of Earl Grey) + (quantity of Orange Pekoe × price of Orange Pekoe). Since the total pounds are given as 600, let the quantity of Earl Grey be x pounds and Orange Pekoe (600 - x) pounds. The equation becomes $4.50 × 600 = $6 × x + $4 × (600-x). Solving this equation gives us the quantities of Earl Grey and Orange Pekoe required.

A person must score in the upper 2% of the population on an iq test to qualify for membership in mensa, the international high-iq society (us airways attache, september 2000). there are 110,000 mensa members in 100 countries throughout the world (mensa international website, january 8, 2013). if iq scores are normally distributed with a mean of 100 and a standard deviation of 15, what score must a person have to qualify for mensa (to the nearest whole number)?
To qualify for Mensa, a person must have an IQ score in the top 2% of the population. Using the normal distribution with a mean of 100 and standard deviation of 15, the minimum qualifying IQ score is approximately 131.
Explanation:To qualify for Mensa, an individual must have an IQ score within the top 2 percent of the population. Given that the IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, we can use the Z-score formula to find the corresponding IQ score.
The Z-score that corresponds to the top 2 percent can be found using a standard normal distribution table or a calculator with inverse normal function. The Z-score for the 98th percentile is approximately 2.05. We can then use the Z-score formula:
Z = (X - Mean) / Standard Deviation
Substituting the values we have:
2.05 = (X - 100) / 15
Solving for X gives us:
X = 2.05 * 15 + 100
X = 130.75
Therefore, the minimum IQ score required to qualify for Mensa, to the nearest whole number, is 131.
