Answer:
lol the answer is the second one
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%.

In 4 MNO if MN = 5 cm, NO = 6 cm and MO = 7 cm, find: a the area of A MNO. b the length of the shortest altitude.
The area of the triangle MNO is 14.7 sq cm and the shortest altitude is 2.1 cm
Finding the area of the triangle MNOFrom the question, we have the following parameters that can be used in our computation:
MN = 5 cm, NO = 6 cm and MO = 7 cm
So, we have
s = 1/2 * (5 + 6 + 7)
Evaluate
s = 9
The area is then calculated as
Area = √[s(s - MN)(s - NO)(s - MO)]
Substitute the known values in the above equation, so, we have the following representation
Area = √[9 * (9 - 5)(9 - 6)(9 - 7)]
Evaluate
Area = 14.7
Also, we have
Shortest altitude = 14.7/7

Dixon and his little sister Ariadne stand next to each other on the playground on a sunny afternoon. Their mother measures their shadows. Ariadne's shadow is 6 feet long and Dixon's shadow is 9 feet long. If Dixon is 6 feet tall, how tall is Ariadne?
Answer: 4
Step-by-step explanation:
We can use the proportion. We already know that Dixon is 6 ft tall and that his shadow is 9 ft long. Also we know that the shadow of his sister is 6 ft long. 6 : x = 9 : 6, or 6 / x = 9 / 6. After that we will cross multiply : 9 * x = 6 * 6, 9 x = 36 , x = 36 : 9, x = 4. Answer: Ariadne is 4 feet tall.Hope I helped! :) Cheers!

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.

Find the distance between the points (1,2) and (10,-10) round decimal to nearest tenth
The distance between the points (1, 2) and (10,-10) is 15 units.
How to determine the distance between the coordinates for each points?In Mathematics and Geometry, the distance between two (2) points that are on a coordinate plane can be calculated by using the following mathematical equation:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Where:
x and y represent the data points (coordinates) on a cartesian coordinate.
By substituting the given points into the distance formula, we have the following;
Distance = √[(10 - 1)² + (-10 - 2)²]
Distance = √[(9)² + (-12)²]
Distance = √[81 + 144]
Distance = √225
Distance = 15 units.

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%.

dimensions.
The width is:
The length is
The length of the rectangle is 43 inches.
The width of the rectangle is 18 inches.
Given that,
The length of a rectangle is seven more than double the width.
Let width = x
Length = 7 + 2x
Perimeter of the rectangle = 122 inches
The formula to find the perimeter of a rectangle is,
Perimeter = 2 (length + width)
Substituting,
122 = 2 (7 + 2x + x)
61 = 7 + 3x
3x = 54
x = 18
Width = 18 inches
Length = 7 + 2x = 7 + 36 = 43 inches
