Answer:

$2253.98

Step-by-step explanation:

Jim received a $2000 loan from his bank. The loan accrues 3% interest every 3 months.

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

P=2000

r= 3%=0.03  and t= 4 years

interest every 3 months so n= 4

[tex]A=2000(1+\frac{.03}{4} )^{4 \cdot 4}[/tex]

[tex]A=2000(1+\frac{.03}{4} )^{16}\\A=2000(1.0075)^{16}\\\\A=2253.98[/tex]

Compound interest is the addition of interest. The interest that is needed to be paid by Jim in the 4 years of tenure is $2253.98.

Compound interest is the addition of interest on the interest of the principal amount. It is given by the formula,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

We know that the Principal amount received by Jim is $2000, while the interest that Jim needs to pay is 3% quarterly, therefore, he needs to pay the interest 4 times a year. Thus, the value of n is 4.

Now, we know all the values therefore, substitute the values in the formula of compound interest,

[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]

[tex]A = 2000(1+ \dfrac{3}{4})^{4 \times 4}\\\\A = \$2,253.98[/tex]

Hence, the interest that is needed to be paid by Jim in the 4 years of tenure is $2253.98.

Answer:

595 Trout

Step-by-step explanation:

90 - 45 = 45

450 + 45 = 495

The estimated number of trout in the lake is 495 trouts.

The total number of trouts in the lakes that were initially tagged is added with the number of untagged trout that are caught afterward to find the total number of trout in the lake.

It is given that 450 trout were initially caught and tagged by a conservationist and were later released into the lake.

Therefore the total number of tagged trout = 450

Later, when the trout are caught again, we notice that 90 are caught and of those 90 trout, 45 have been tagged. This means that there are 45 untagged trout.

Therefore, total number of untagged trout = 90 - 45

= 45

Therefore, the total number of trout in the lake = 450 + 45

= 495

Thus, we have found that the estimated number of trout in the lake is 495 trouts.

By first calculating the Garcia family's travel rate of 409 miles per day, we can estimate it will take them approximately 9 days to travel from San Diego, California to Bar Harbor, Maine.

The subject of this question is Mathematics, and it involves understanding and applying the concept of rate – the speed at which something happens over a particular period of time. In this case, we have the Garcia family traveling from San Diego, California, to Bar Harbor, Maine. They have traveled 2,045 miles in 5 days.

To find out how long it will take them to travel the entire way, we first need to calculate the rate at which they are traveling. We do that by dividing the total distance they have traveled by the total number of days it took them to travel that distance: 2045 miles / 5 days = 409 miles per day.

The distance from San Diego to Bar Harbor is about 3,305 miles. So, if they continue to travel at a rate of 409 miles per day: 3305 miles / 409 miles per day = about 8.08 days. Since they can't travel a fraction of a day, we'll round that up to 9 days. So it will take them approximately 9 days to travel from San Diego to Bar Harbor at their current rate.

Answer: The value of a is 2 and the value of b is 3.

Step-by-step explanation:

Given : △CDE maps to △STU with the transformations (x, y) → (x − 2, y − 2) →(3x, 3y)

The first transformation is a translation ,so there will be no change in the length of the sides ∵  translation is a rigid motion.

The second transformation is a dilation ,so there will be a change in the length of the sides by scale factor of 3. ∵  dilation is not a rigid motion.

Basically , by combining both transformation:

Length of Side in  △STU = 3 x (Corresponding side in △CDE )

⇒ ST = 3CD   and TU  = 3 DE

If CD = a + 1, DE = 2a − 1, ST = 2b + 3 and TU = b + 6 , then

2b + 3=3(a + 1)  and b + 6 = 3(2a − 1)

⇒ 2b + 3=3a+3 and  b + 6 = 6a-3

⇒ 3a-2b=0        (i)   and b = 6a-9             (ii)

Put value of b from (ii) in (i)  , we get

3a-2(6a-9)=0

⇒ 3a-12a+18=0

⇒ -9a=-18

⇒ a= 2

Put value of a in (ii) , we get

b= 6(2)-9

=12-9=3

Hence, the value of a is 2 and the value of b is 3.

Answer: she must score 83% on her 4th test if she wants to get a final average of 75%

Step-by-step explanation:

The formula for determining average is expressed as.

Average = sum of the score/ number of tests.

Sara got a 70%, 64%, and 83% on her first three tests. Her former average would be

(70 + 64 + 83) 217/3 = 72.3℅

Let x represent the score that she needs to get on her 4th test if she wants to get a final average of 75%.

Therefore,

(x + 217)/4 = 75

Cross multiplying by 4, it becomes

x + 217 = 300

x = 300 - 217

x = 83%

[tex]C(x) = 45x + 75\\\text{where x is the width of rectangular pen}[/tex]

Step-by-step explanation:

We are given the following in the question:

The length of the pen will be 5 feet more than twice as long as the width of the pen.

Let y be the length and x be the width. Thus, we can write:

[tex]y = 2x +5[/tex]

Fencing = Perimeter of rectangular pen

[tex]\text{Perimeter of rectangle} = 2(\text{length} + \text{width})\\ P = 2(y+x)\\P=2(2x+5+x)\\P= 2(3x+5)\\P = (6x + 10)\text{ feet}[/tex]

The cost of the pen will be $7.50 per foot of fencing.

Total Cost of fencing =

[tex]\text{Cost of fencing}\times \text{Perimeter}\\C(x) = 7.50\times (6x+10)\\C(x) = 45x + 75\\\text{where x is the width of rectangular pen}[/tex]

is the required cost function.

Final answer:

The cost function for fencing a rectangular pen, given the width x and a cost of $7.50 per foot, is c(x) = 45x + 75, representing the total cost as a function of the width x.

Explanation:

The student is asking for a function that represents the cost of fencing a rectangular pen when the width is given. Let x be the width of the pen. The length of the pen, according to the problem, is 5 feet more than twice the width, so it can be expressed as 2x + 5 feet.

The cost of the fencing is $7.50 per foot. To find the total cost of the pen, we have to calculate the perimeter of the rectangular pen, which is 2 times the width plus 2 times the length. Hence, the perimeter P(x) can be represented as P(x) = 2x + 2(2x+5).

Multiplying through and simplifying gives us the cost function c(x) = 7.50 * P(x). Therefore, c(x) = 7.50 * (2x + 2(2x + 5)) = 7.50 * (6x + 10) = 45x + 75. This function represents the cost of fencing the pen as a function of its width x.

Answer:

Dimensions are 8 Inches by 14 inches by 20 inches

Step-by-step explanation:

The volume of the box is 2240. This means:

lbh = 2240

Where b is the width.

Width is two inches less than twice the height

b = 2h - 2

length is 4 inches less than 3 times the height

l = 3h - 4

Substituting these parameters into the lbh equation will yield the following:

h * (3h - 4) * (2h - 2) = 2240

h[6h^2-14h+8] = 2240

6h^3 -14h^2 + 8h - 2240= 0

Solving this cubic equation will yield one of the values to be 8. The other two values are complex numbers.

b = 2h - 2

l = 3h - 4

b = 2(8) - 2 = 14

l = 3(8) - 4 = 20

In total you won) 25 + 50= 75 bucks.

You dropped 140bucks in total.

140- 75= 65 bucks.

Therefore, You lost 65bucks.

This question deals with Mathematics, specifically the concept of profit and loss. Despite winning a total of $75 over 10 weeks at the slots, you lose $2 everyday, totaling to $140 in losses over the ten weeks. Hence, you end up with a net loss of $65.

The subject of this question is related to Mathematics and more specifically on the concept of profit and loss. Here you have won a total of $75 over 10 weeks, but each day you play slot machines you lose $2. Given that a week has 7 days, you’ve lost $2 * 7 days/week * 10 weeks = $140 over the course of 10 weeks. So, despite seeming to 'win' at the slot machine, when we subtract the total loss from total gain, $75 - $140, we find that you've actually ended up with a net loss of $65.

Answer: Polaris would appear at [tex]26\°[/tex] latitude

Step-by-step explanation:

Let's begin by explaining that Latitude is the angular distance between the Earth's equator, and a specific point on the planet. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.  

In this sense, latitude [tex]0\°[/tex] refers to the equatorial line that divides the Earth in two hemispheres (North and South), and Miami's latitude [tex]26\°[/tex] refers to the Northern hemisphere.

On the other hand, talking about the North Star (also known as Polaris); if we were just in the North Pole (latitude [tex]90\°[/tex]), Polaris would by exactly over our heads or the zenith ([tex]90\°[/tex] over the horizon), but as we go until latitude [tex]26\°[/tex], Polaris altitude will be approximately at that same angle over the horizon.

Hence, from an observer located in Miami, Polaris would appear at [tex]26\°[/tex] N.

In Miami, with a latitude of 26° N, the North Star appears at an altitude of 26° above the horizon. As you move southward, it appears lower; when you travel north, it appears higher. Precise navigation also considers the slight angular difference between Polaris and the true celestial pole.

In Miami, Florida, which has a latitude of 26° N, the North Star, or north celestial pole, would appear at an altitude of 26° above the northern horizon. This is because the altitude of the North Star above the horizon is roughly equivalent to the latitude of the observer's location in the Northern Hemisphere. Therefore, as one drives southward from Miami to a city at a lower latitude, the North Star would appear lower in the sky. Conversely, driving northward would make the North Star appear higher.

It's important to note that due to the Earth's curvature, as you move southward from Miami, both the North Star and the southern sky would appear to sink, while the opposite would occur as you move northward. If you were to reach the equator, the North Star would align with the northern horizon, and it would not be visible from latitudes south of the equator. For precision in navigation or astronomy, one must also account for the small angular distance between Polaris and the true north celestial pole.

Final answer:

George will weigh 172 pounds after four years of college, gaining 0.25 pounds per month. If he continues this trend for 10 more years, he will weigh 202 pounds at his 10-year college reunion.

Explanation:

To calculate the weight gain of George after college and for the next 10 years, we can use simple arithmetic. George starts at 160 pounds and gains 0.25 pounds each month.

Weight After College

Four years of college is equivalent to 4 years × 12 months/year = 48 months. If he gains 0.25 pounds each month, then over 48 months he will have gained:

0.25 pounds/month × 48 months = 12 pounds.

So, after college, his weight will be:

160 pounds + 12 pounds = 172 pounds.

Weight After Next 10 Years

To calculate his weight after the next 10 years, which is 10 years × 12 months/year = 120 additional months, we do the following calculation:

0.25 pounds/month × 120 months = 30 pounds gain.

Adding this to his weight after college:

172 pounds + 30 pounds = 202 pounds.

Therefore, for his 10-year college reunion, George will weigh 202 pounds.

Answer:

6 baseball games remain in the season.

Step-by-step explanation:

Let the number of baseball games remaining be 'x'.

Given:

Number of innings in 1 baseball game = 9

Number of innings to be played at home = 45

Number of innings to be played away from home = 45

Total number of innings played in the given season = 36

Now, total number of innings to be played in a season is equal to the sum of the innings played at home and away from home.

So, Total number of innings = 45 + 45 = 90 innings.

Now, out of 90 innings, 36 innings are already played.

So, the number of innings that remain is given as:

Innings remaining = Total innings - Innings already over

Innings remaining = 90 - 36 = 54

Now, 9 innings is equivalent to 1 baseball game.

So, 54 innings is equivalent to 'x' baseball games.

Setting up a proportion and solving by cross multiplication, we get:

[tex]\frac{9}{1}=\frac{54}{x}\\\\9x=54\\\\x=\frac{54}{9}=6[/tex]

Therefore, 6 baseball games remain in the season.
