complete question:
A dentist orders 15 boxes of floss and 20 boxes of toothbrushes each month. Floss is sold 70 to a box and toothbrushes are sold 50 to a box . how many items does the dentist order each month.
Answer:
The dentist orders 1050 number of floss and 1000 number of toothbrushes. The items are 2 different items namely floss and toothbrushes.
Step-by-step explanation:
The dentist orders 15 boxes of floss and 20 boxes of toothbrushes each month.
The floss is sold 70 to a box, this means about 70 numbers of floss occupies each box of floss. To get the total number of floss items in the 15 boxes of floss, we have to multiply the number of boxes of floss by the number of floss present in each box. Mathematically,
70 × 15 = 1050 items of floss
The boxes of toothbrushes is 20 . For each box the number of toothbrushes is 50 . To get the total number of tooth brushes we multiply the number of boxes by the total number of toothbrushes in each box.
50 × 20 = 1000 items of toothbrushes.
The dentist orders 1050 number of floss and 1000 number of toothbrushes. The items are 2 different items namely floss and toothbrushes.
For commission as a realtor, Michelle earns $349 plus 3% of the purchase price for each home she helps buy or sell. If she earned $8,965 in commission on a certain home, find its purchase price.
ANSWER:
$8965- $349= $8616
3/100x= 8616
8616 x 100/ 3= $287,200.
I'm posting this because somebody inboxed me asking for help and before I even got to help them, they deleted the inbox and i couldn't remember their name. I hope you see this and benefit from it, sorry!
Well, let us solve this step by step.
We know that Michelle earns 349 plus 3% of the Purchase price. Let us call the Purchase price as P, so that:
Earnings, E = 349 + 0.03 P
So if she earns 8,965 (E = 8,965) so we can find P:
8,965 = 349 + 0.03 P
0.03 P = 8,616
P = $287,200
Michelle's total commission from a house sale was $8,965, from which $349 is a fixed commission. The rest, $8616, represents the 3% of the selling price of the house. By solving the simple equation $8616 = 0.03 * X, we find that the home price is $287,200.
Explanation:This problem is a simple, but common, practice in the world of linear equations. The first step is to understand that the base commission of $349 is a constant that Michelle earns every time, whilst the remaining part of her commission comes from the 3% percentage of the sale price. After subtracting the base commission from the total commission, we get a value of: $8965 - $349 = $8616. This value is equal to 3% of the house price.
We can express this as: 8616 = 0.03 * X, where X is the value of the house. By isolating X (the house price), we divide both sides by 0.03 to get the house price. Therefore, the home price would be $8616 / 0.03 = $287,200.

Megan Mei is charged 2 points on a $120,000 loan at the time of closing. The original price of the home before the down payment was $140,000. How much do the points in dollars cost Megan? A. $4,200 B. $2,800 C. $8,200 D. $2,400
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Amount of original price of the home before the down payment = $140000
Amount of loan at the time of closing = $120000
Megan Mei is charged 2 points on that amount means
[tex]2\%\ on\ \$120000\\\\=\frac{2}{100}\times 120000\\\\=0.02\times 120000\\\\=\$2400[/tex]
Hence, Option 'A' is correct.

Graph parallelogram ABCD on a coordinate plane with vertices A(3,4) B(6,1) C(0,-2) and D(-3,1).
Find the slope of each side.
What do you notice about the slopes?
A parallelogram, the opposite sides have equal slopes.
To graph the parallelogram ABCD on a coordinate plane, we can plot the given points A(3,4), B(6,1), C(0,-2), and D(-3,1), and then connect them in order to form the parallelogram.
Here are the steps to find the slope of each side:
Plot the Points:
Plot the points A(3,4), B(6,1), C(0,-2), and D(-3,1) on the coordinate plane.
Connect the Points:
Connect the points in order (A to B to C to D to A) to form the parallelogram.
Find the Slope:
The slope of a line passing through two points
(x_1 ,y_1 ) and (x_2 ,y_2 ) is given by the formula m= y_2 -y_1/ x_2- x_1
Calculate the slope for each pair of consecutive points:
Slope of AB: mAB = 1−4/6−3
Slope of BC: mBC = −2−1/0−6
Slope of CD: mCD = 1−(−2)/−3−0
Slope of DA: mDA = 4−1/ 3−(−3)
Now, observe the slopes:
mAB and mCD
are the slopes of opposite sides. They should be equal for a parallelogram.
mBC and mDA are the slopes of the other pair of opposite sides. They should also be equal for a parallelogram.
So, for a parallelogram, the opposite sides have equal slopes.

Solve the equation V=1/3 Bh for B
To solve the equation V = 1/3 Bh for B, multiply both sides by 3 to eliminate the fraction and then divide by h, resulting in B = 3V/h.
The equation given is V = 1/3 Bh, where V represents volume, B is the area of the base of the three-dimensional figure, and h is the height. To solve for B, the area of the base, you need to isolate B on one side of the equation. Follow these steps:
Multiply both sides of the equation by 3 to get rid of the fraction on the right-hand side, resulting in 3V = Bh.Next, to solve for B, divide both sides of the equation by h, which gives you B = 3V/h.Therefore, the formula B = 3V/h is used to calculate the base area B given the volume V and height h of the figure.
Find the surface area of the surface given by the portion of the paraboloid z=3x2+3y2 that lies inside the cylinder x2+y2=4. (hint: convert to polar coordinates after setting up the integral)
To find the surface area of the specified area in the paraboloid, convert the original cartesian coordinates to polar coordinates. Then set up and solve the appropriate double integral over the region defined by the circle in polar coordinates.
Explanation:To find the surface area of a paraboloid z=3x²+3y² inside the cylinder x²+y²=4, you first set up the integral and then convert to polar coordinates. As per the given paraboloid equation, we know that dz/dx = 6x and dz/dy = 6y. Therefore, the differential of surface area in polar coordinates can be given as √(1+(6r*cosø)²+(6r*sinø)²) rdrdø.
Next, integrate this over the area of a circle in polar coordinates, from r=0 to r=2 and ø=0 to ø=2π. The limits of 2 and 2π come from the given cylinder equation x²+y²=4, which represents a circle of radius 2 in polar coordinates.
The final integral in terms of r and ø should yield the desired surface area of the paraboloid which lies inside the cylinder.

lim x→25 x−25 /√x−5
Final answer:
The solution involves multiplying by the conjugate of the denominator to simplify the expression, leading to the finding that the limit as x approaches 25 of (x-25)/(√x-5) equals 10.
Explanation:
The question asks to evaluate the limit lim x→25 (x−25)/(√x−5). At first glance, directly substituting x = 25 into the equation would lead to a 0/0 form, indicating a need for algebraic manipulation to resolve the indeterminate form.
To simplify, we can multiply the numerator and the denominator by the conjugate of the denominator, which is (√x + 5). This approach is helpful in dealing with limits that involve square roots.
Following this step:
Multiply both the numerator and denominator by (√x + 5).
The numerator becomes (x - 25)(√x + 5).
The denominator turns into x - 25 after applying the difference of squares.
Simplify to get (√x + 5), since (x - 25) in numerator and denominator cancel out.
Finally, substitute x = 25 into the simplified form to get 10 as the answer. Therefore, lim x→25 (x−25)/(√x−5) = 10
