You want to purchase a new car
In 9 years and expected the car to cost $15,000. Your bank offers a plan a guaranteed APR of 6.5% .
If you make regular deposits.
How much should you deposit each month to end up $15,000 in 9 years ? 
The approximate amount to be deposited each month at a guaranteed APR of 6.5% that will accrue to $15,000 in 9 years is $97.57.
Future value for an annuityIn order to find out how much you should deposit each month to end up with $15,000 in 9 years, we can use the future value formula for an annuity:
FV = PMT * [(1 + r)^n - 1] / r
where:
FV is the future valuePMT is the deposit amountr is the monthly interest raten is the total number of deposits (in months).The total number of deposits, n, is the number of months in 9 years:
n = 9 * 12 = 108
The monthly interest rate from the annual percentage rate (APR):
r = (1 + 0.065/12) - 1 = 0.0054166667
Let's substitute the values and solve for PMT:
15,000 = PMT * [(1 + 0.0054166667)^108 - 1] / 0.0054166667PMT = 15,000 / [(1 + 0.0054166667)^108 - 1] * 0.0054166667PMT ≈ $97.57Therefore, you should deposit approximately $97.57 each month to end up with $15,000 in 9 years, assuming a guaranteed APR of 6.5%.

Mr. Cosgrove, a farmer, needs to build a new feed trough for his goats. The trough will be in the shape of a rectangular prism and hold approximately 20 gallons, or 4,620 cubic inches, of food. The height of the trough will be 6 inches so that the goats can access their food easily. Mr. Cosgrove decides to make the trough 8 times as long as it is wide so all his goats can eat at the same time.
Which equation can you use to find the width of the feed trough?
A.) 4,620w = 8 x w x 6
B.) 4,620 = 8w x w x 6
To the nearest tenth of an inch, how wide will the feed trough be?
___ inches wide
The correct equation to find that can be used to find the width of the feed trough is (b) 4620 = 8w×w×6, and the width of the "feed-trough" is 9.8 inches wide.
The "Volume" of "rectangular-prism" can be found using formula V = l×w×h, where V is = volume, l is = length, w is = width, and h is = height.
We know that the volume of the "feed-trough" is 4,620 cubic inches, and
The height is = 6 inches. Let us denote the width as "w" and the length as "8w" (because trough's length is 8 times the width),
So, the equation for the volume of the feed trough is:
⇒ 4620 = (8w) × (w) × (6),
So, the correct equation to find the width is Option (b) 4620 = (8w) × (w) × (6).
Simplifying further,
We get,
⇒ w² = 96.25,
⇒ w ≈ 9.8 inches (rounded to the nearest tenth)
Therefore, the width of the feed trough will be approximately 9.8 inches.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C? On a coordinate plane, triangle A has points (1, negative 2), (3, negative 2), (3, negative 5). Triangle B has points (4, 0), (6, 0), (6, negative 3). Triangle C has points (4, 0), (6, 0), (6, 3). A Is congruent to B and B Is congruent to C A Is congruent to A, B Is congruent to B, C Is congruent to C Each triangle is a right triangle. Each triangle is an isosceles triangle.
Triangle A and Triangle C are congruent to each other because a series of rigid transformations, a translation and a reflection, were applied to A to form C. Therefore, the correct answer is "A Is congruent to B and B Is congruent to C". So, the correct answer is A).
Identify the coordinates of the vertices of Triangle A and Triangle C
Triangle A: (1, -2), (3, -2), (3, -5)
Triangle C: (4, 0), (6, 0), (6, 3)
Apply the first transformation that was used to transform Triangle A to Triangle C, which is a translation of 3 units right and 2 units up. To do this, add 3 to the x-coordinates and add 2 to the y-coordinates of each vertex of Triangle A to get
Triangle A': (4, 0), (6, 0), (6, -3)
Triangle A' is not congruent to Triangle A because the translation changes the position of the vertices, but it does not change the size or shape of the triangle.
Apply the second transformation that was used to transform Triangle A' to Triangle C, which is a reflection over the x-axis. To do this, negate the y-coordinates of each vertex of Triangle A' to get
Triangle C': (4, 0), (6, 0), (6, 3)
Triangle C' is congruent to Triangle C because the reflection over the x-axis preserves the size and shape of the triangle, and negating the y-coordinates of the vertices only changes their position, not their size or shape.
Compare Triangle A with Triangle C'
Triangle A: (1, -2), (3, -2), (3, -5)
Triangle C': (4, 0), (6, 0), (6, 3)
We can see that Triangle A is congruent to Triangle C' because they have the same shape and size, and the corresponding angles and sides are equal.
Therefore, since Triangle A is congruent to Triangle C', and Triangle C' is congruent to Triangle C, we can conclude that Triangle A is congruent to Triangle C.
Therefore, the correct answer is "A Is congruent to B and B Is congruent to C" and option is A).

Find the area of a regular hexagon with apothem mm. Round to the nearest whole number.
31 mm2
94 mm2
187 mm2
125 mm2
The area of the regular hexagon with apothem 3√3 mm is approximately 125 mm². (option d)
The area of a regular hexagon can be found using the formula:
Area = (3√3 × s²) ÷ 2
Where s is the length of one side of the hexagon, and 3√3 is the apothem.
To solve for the area, we need to find the value of s. We can do this by using the fact that a regular hexagon can be divided into six equilateral triangles, and each of these triangles has sides equal to s.
The height of each equilateral triangle is equal to the apothem, which is 3√3 mm in our case. Using the Pythagorean theorem, we can find the length of one side of the hexagon:
s = 2 × (3√3) ÷ √3
s = 6
Now that we know the value of s, we can substitute it into the formula for the area of a regular hexagon:
Area = (3√3 × 6²) ÷ 2 = 125
Hence the correct option is (d).

The coordinates of the vertices for the image if the preimage is translated 3 units up is A′(−3, 6), B′(0, 10), C′(−3, 3) (option b).
In this particular question, we are given a triangle ABC with vertices at A(−3, 3), B(0, 7), and C(−3, 0). Our task is to determine the coordinates of the vertices for the image if the preimage is translated 3 units up.
When a figure is translated, it is moved to a new location without changing its shape or size.
Let's start by looking at vertex A(−3, 3). If we translate this vertex 3 units up along the y-axis, its new coordinates will be A′(−3, 6).
Similarly, if we translate vertex B(0, 7) 3 units up, its new coordinates will be B′(0, 10). Finally, if we translate vertex C(−3, 0) 3 units up, its new coordinates will be C′(−3, 3).
Therefore, the vertices of the image triangle are A′(−3, 6), B′(0, 10), and C′(−3, 3). This is option (B) from the given answer choices.

how do you find the height of a composite figure made up of 2 different 3-d shapes?
In order to find the height of 2 different 3-D shapes, we must identify which dimension represents the height for each individual shape and then add them together.
How can we determine height of the composite 3-D figure?The first thing is that we must identify which dimension represents the height for each individual shape, for instance, if one shape is a rectangular prism, its height would be the length of one of its sides.
After we identified the height for each shape, you can add them together to get the total height of the composite figure, but, we must understand that this method assumes that the two shapes are stacked vertically on top of each other with their bases aligned.

Suppose that prices of a certain model of new homes are normally distributed with a mean of $150,000. Use the 68-95-99.7 rule to find the percentage of buyers who paid:
between $150,000 and $156,000 if the standard deviation is $2000.
About 49.87% of buyers paid between $150,000 and $156,000 for the new homes.
According to the 68-95-99.7 rule, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations of the mean, and 99.7% falls within three standard deviations of the mean in a normal distribution.
In this case, the mean price of a certain model of new homes is $150,000, and the standard deviation is $2000. Thus, we can calculate the price range of one standard deviation above and below the mean as:
Lower Bound = Mean - 1 × Standard Deviation = $150,000 - $2,000 = $148,000
Upper Bound = Mean + 1 × Standard Deviation = $150,000 + $2,000 = $152,000
Therefore, approximately 68% of buyers paid between $148,000 and $152,000 for the new homes.
To find the percentage of buyers who paid between $150,000 and $156,000, we need to calculate the z-scores for these values using the formula:
z-score = (value - mean) / standard deviation
For $150,000:
z-score = ($150,000 - $150,000) / $2,000 = 0
For $156,000:
z-score = ($156,000 - $150,000) / $2,000 = 3
Looking at the z-score table, we can see that the area under the normal curve between z = 0 and z = 3 is approximately 49.87%.

Find the value of x. Then find the area of the triangle.
Step-by-step explanation:
law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c are the sides, A, B, C are the corresponding opposite angles.
so,
16/sin(90) = x/sin(30)
16/1 = x/0.5
0.5 × 16 = x
x = 8 units
Pythagoras now gets us half the baseline (and therefore the full baseline) :
16² = x² + (baseline/2)² = 8² + (baseline/2)²
256 = 64 + baseline²/4
192 = baseline²/4
768 = baseline²
baseline = sqrt(768) = sqrt(256×3) = 16×sqrt(3) units
the area of a triangle is
