The greatest whole number that rounds to 500 when rounding to the nearest hundred is 550.
When rounding a number to the nearest hundred, you need to look at the digit in the tens place. If that digit is 5 or greater, you round up the hundreds digit; if it is less than 5, you round down the hundreds digit.
For example, let's say we have the number 2,548. The digit in the tens place is 4, which is less than 5, so we round down the hundreds digit (2) to get 2,500.
Now, if we are looking for the greatest whole number that rounds to 500 when rounded to the nearest hundred, we need to find the largest number that has 5 in the tens place and 0 in the ones place. That number is 550. When we round 550 to the nearest hundred, we get 500.
Therefore, the greatest whole number that rounds to 500 when rounded to the nearest hundred is 550.

what is the radius of a basketball if the volume is 11488.2 cm? round your answer the the nearest whole number. use 3.14 as π .
Answer:
The radius of the basketball is 20 cm.
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr^3, where V is the volume and r is the radius.
We are given that the volume of the basketball is 11488.2 cm, so we can set up the equation:
11488.2 = (4/3)πr^3Simplifying, we get:
(4/3)πr^3 = 11488.2Dividing both sides by (4/3)π, we get:
r^3 = 11488.2 / (4/3)πr^3 = 7239.79Taking the cube root of both sides, we get:
r ≈ 20Rounding to the nearest whole number, the radius of the basketball is 20 cm.
A segment with endpoints A (4, 2) and C (1,5) is partitioned by a point B such that AB and BC form a 1:3 ratio. Find B.
O (1, 2. 5)
O (2. 5, 3. 5)
O (3. 25, 2. 75)
O (3. 75, 4. 5)
The answer is (3.25, 2.75)
To find point B, we can use the fact that AB and BC form a 1:3 ratio. Let's start by finding the coordinates of point B.
First, we need to find the distance between A and C. We can use the distance formula for this:
[tex]d = \sqrt{ ((x2 - x1)^2 + (y2 - y1)^2)[/tex]
where [tex](x1, y1) = (4, 2)[/tex] and [tex](x2, y2) = (1, 5)[/tex]
[tex]d = \sqrt{((1 - 4)^2 + (5 - 2)^2)} = \sqrt{(9 + 9)} = \sqrt{(18)}[/tex]
Next, we need to find the distance between A and B, which we'll call x, and the distance between B and C, which we'll call 3x (since AB and BC are in a 1:3 ratio).
Using the distance formula for AB:
[tex]x = \sqrt{\\((x2 - x1)^2 + (y2 - y1)^2)[/tex]
where [tex](x1, y1) = (4, 2)[/tex] and [tex](x2, y2) = (Bx, By)[/tex]
[tex]x = \sqrt{((Bx - 4)^2 + (By - 2)^2)[/tex]
Using the distance formula for BC:
[tex]3x = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)[/tex]
where [tex](x1, y1) = (1, 5)[/tex] and [tex](x2, y2) = (Bx, By)[/tex]
[tex]3x = \sqrt{((Bx - 1)^2 + (By - 5)^2)[/tex]
Now we can set up an equation using the fact that AB and BC are in a 1:3 ratio:
[tex]x / 3x = 1 / 4[/tex]
Simplifying this equation, we get:
[tex]4x = 3(AB)[/tex]
[tex]4x = 3\sqrt{((Bx - 4)^2 + (By - 2)^2)[/tex]
And
[tex]9x = \sqrt{((Bx - 1)^2 + (By - 5)^2)[/tex]
Now we have two equations and two unknowns (Bx and By). We can solve for Bx in the first equation and substitute into the second equation:
[tex]Bx = (3\sqrt{((Bx - 4)^2 + (By - 2)^2))} / 4[/tex]
[tex]9x = \sqrt{((Bx - 1)^2 + (By - 5)^2)[/tex]
[tex]81((Bx - 4)^2 + (By - 2)^2) / 16 = (Bx - 1)^2 + (By - 5)^2[/tex]
Expanding the squares and simplifying, we get:
[tex]81Bx^2 - 648Bx + 1245 = 16Bx^2 - 32Bx + 266[/tex]
[tex]65Bx^2 - 616Bx + 979 = 0[/tex]
Using the quadratic formula, we get:
[tex]Bx = (616 ± \sqrt{(616^2 - 4(65)(979)))} / (2(65))[/tex]
[tex]Bx = (616 ± \sqrt{(223456))} / 130[/tex]
[tex]Bx = 3.25[/tex] or [tex]Bx = 10.2[/tex]
We can eliminate the solution Bx ≈ 10.2 because it is outside the segment AC. Therefore, the solution is:
B = (3.25, 2.75)

Matt knows 4 x 6 = 24. what other math fact does this help matt remember? circle the letter of the correct answer. sadie chose a 6 + 4 = 10 as the correct answer. how did she get that answer?
The math fact that 4 x 6 = 24 helps Matt remember that 6 x 4 = 24, and Sadie arrived at the answer 10 for 6 + 4 by incorrectly adding the numbers in reverse order.
Matt knows that 6 x 4 = 24. This helps him remember that 4 x 6 and 6 x 4 are both equal to 24.
The math fact that Matt can remember based on 4 x 6 = 24 is that multiplication is commutative. This means that the order of the numbers being multiplied doesn't affect the result. So, if 4 multiplied by 6 equals 24, it also implies that 6 multiplied by 4 would give the same result of 24.
Sadie arrived at the answer 10 for 6 + 4 by mistakenly swapping the order of the numbers and performing the addition incorrectly. The correct sum for 6 + 4 is indeed 10. Sadie's error demonstrates the importance of following the correct order of operations, where addition should be performed after ensuring the numbers are in the correct order.
As for Sadie's answer of 6 + 4 = 10, it is not directly related to the multiplication fact that Matt knows.
It is possible that Sadie used a different math fact or strategy to arrive at that answer.

If c(t) = 53.2te^{- 0.26} measures the concentration, in ng/ml of a drug in a person's system thours after the drug is administered. a) What is the peak concentration of the drug? b) When does the drug reach peak concentration?
(a) To find the peak concentration of the drug, we need to find the maximum value of c(t). Since c(t) is an exponential function, its maximum value occurs at its maximum point, which is where its derivative is equal to zero. We can find this point by taking the derivative of c(t) and setting it equal to zero:c'(t) = 53.2e^{-0.26} - 13.832te^{-0.26} = 0Solving for t, we get t = 3.870 hours. Therefore, the peak concentration of the drug is c(3.870) = 109.2 ng/ml.(b) To find when the drug reaches peak concentration, we have already found that it occurs at t = 3.870 hours.

The peak concentration of the drug is approximately 42.83 ng/ml, and it occurs around 3.85 hours after the drug is administered.
To find the peak concentration of the drug and when it reaches that peak, we'll need to consider the given function c(t) = 53.2te^(-0.26t), where t is the time in hours.
a) To find the peak concentration, we need to determine the maximum value of c(t). We can do this by taking the first derivative of c(t) with respect to t and setting it equal to 0.
c'(t) = 53.2(-0.26)e^(-0.26t) + 53.2e^(-0.26t) = 0
Now, solve for t:
t ≈ 3.85 hours
b) Plug the value of t back into the c(t) function to find the peak concentration:
c(3.85) = 53.2(3.85)e^(-0.26(3.85)) ≈ 42.83 ng/ml
So, the peak concentration of the drug is approximately 42.83 ng/ml, and it occurs around 3.85 hours after the drug is administered.

Hannah has an offer from a credit card issuer for 0% APR for the first 30 days
and 12. 22% APR afterwards, compounded daily. What effective interest rate
is Hannah being offered?
To find the effective interest rate that Hannah is being offered, we need to take into account the compounding period, which is daily in this case. The effective annual interest rate (EAR) can be calculated using the formula:
EAR = (1 + APR/n)^n - 1
where APR is the annual percentage rate, and n is the number of compounding periods per year.
For the first 30 days, Hannah is offered a 0% APR, so the EAR for this period is simply 0.
After 30 days, Hannah is offered a 12.22% APR compounded daily, which means that there are 365 compounding periods per year. Therefore, the EAR for this period can be calculated as follows:
EAR = (1 + 0.1222/365)^365 - 1
≈ 0.1267

If An oil globe made of hand-blown glass of a diameter of 22.6. Therefore, the volume of the oil globe is approximately 5704.8 cm^3.
The volume of a spherical object can be calculated using the formula:
V = (4/3)πr^3
where V is the volume, π is the mathematical constant pi (approximately equal to 3.14159), and r is the radius of the sphere.
In this case, we are given the diameter of the oil globe, which is 22.6. The radius is half of the diameter, so we can calculate the radius as:
r = d/2 = 22.6/2 = 11.3 cm
Substituting this value of radius in the formula for the volume of a sphere, we get:
V = (4/3)π(11.3)^3

We know that P = $15,500 and A(t) = $8,400, so we can plug in these values to solve for r:
$8,400 = $15,500(1 - r)^t
Divide both sides by $15,500:
0.54 = (1 - r)^t
Take the logarithm of both sides:
log(0.54) = t*log(1 - r)
Solve for r:
log(0.54)/t = log(1 - r)
1 - r = 10^(log(0.54)/t)
r = 1 - 10^(log(0.54)/t)
Plugging in t = 7 (since the car has depreciated for 7 years), we get:
r = 1 - 10^(log(0.54)/7) ≈ 9.35%
Therefore, the car depreciated at an annual rate of approximately 9.35%.

Find the value of b. Round your answer to the nearest hundredth.

The value of the tangent segment b is 20.15.
What is the value of side b?The secant-tangent power theorem, also known as the tangent-secant theorem, states that if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment.
It is expressed as:
( tangent segment )² = External part of the secant segment + Secant segment.
From the diagram:
Tangent segment = WX = b
External part of the secant segment = YX = 14
Secant segment = ZX = 15 + 14 = 29
Plug these values into the above formula and solve for b.
( tangent segment )² = External part of the secant segment + Secant segment.
b² = 14 × 29
b² = 406
b = √406
b = 20.15
Therefore, the value of b is 20.15.

Add one number to each column of the table so that it shows a function
To add one number to each column of the table and make it show a function, we need the specific table or information about the columns to provide a precise answer.
How to create a function?To transform the given table into a function, we need to add a column that represents the output values corresponding to each input value. A function relates each input value to a unique output value.
Here is an example of how the table could be modified to represent a function:
Input (x) Output (y)
1 3
2 5
3 7
4 9
In this modified table, the output values (y) are obtained by adding 2 to each input value (x). This ensures that each input value is associated with a unique output value, satisfying the definition of a function.

A bag of M&Ms has 4 blue, 8 red, 6 orange, 12 green M&Ms of equal size. If one M&M is selected at random, what is the probability it is NOT red?
The probability of selecting an M&M that is not red is 11/15.To find the probability of selecting an M&M that is not red, we need to first find the total number of M&Ms in the bag,
It is the sum of the number of M&Ms of each color: 4 + 8 + 6 + 12 = 30.
Next, we need to find the number of M&Ms that are not red, which is the sum of the number of M&Ms of all other colors: 4 + 6 + 12 = 22.
Therefore, the probability of selecting an M&M that is not red is 22/30, which can be simplified by dividing both the numerator and the denominator by 2:
22/30 = 11/15
So the probability of selecting an M&M that is not red is 11/15.
In other words, there is an 11/15 chance that the selected M&M will be blue, orange, or green, and a 4/15 chance that it will be red.It is important to note that this assumes that each M&M is equally likely to be selected, and that the bag is well-mixed so that each M&M has an equal chance of being chosen.

The missing side length of the rectangle is 7.75 inches when x is equal to 3. This is obtained by using the Pythagorean theorem to solve for the length of the other side, which is approximately 6.3 inches.
Using the Pythagorean theorem, we can find the missing side length of the rectangle
a² + b² = c²
where c is the length of the diagonal and a and b are the lengths of the sides.
Plugging in the values given, we get
(2x)² + b² = (8x)²
4x² + b² = 64x²
b² = 60x²
b = √(60x²) = √(60)x
When x = 3, the missing side length is
b = √(60)(3) = 7.75 in. (rounded to the nearest tenth of an inch)

A sheet of dough has six identical circles cut from
it. Write an expression in factored form to represent the
approximate amount of dough that is remaining. Is
there enough dough for another circle
Approximate amount of dough that is remaining. Is (length - 2r)(width - 3r) - 6πr^2.
Without the size of the original sheet of dough or the size of the circles cut from it, it's not possible to give an exact expression. However, assuming that each circle has the same radius of 'r' and the original sheet of dough was a rectangle, we can write an expression in factored form for the remaining area of the dough:
Remaining area of dough = (Area of original rectangle) - 6(Area of circle)
= (length x width) - 6(πr^2)
= (length - 2r)(width - 3r) - 6πr^2
Whether there is enough dough for another circle would depend on the size of the circles and the original sheet of dough.
