Answer:To solve this problem, we need to use the formulas for the area and perimeter of a triangle.
Let's start by using the formula for the area of a triangle:
Area = (base x height) / 2
where base and height are the length and height of the triangle's base, respectively.
Let's assume that the base of the triangle is x meters, and the height is y meters. Then we have:
Area = (x*y)/2 = 0.45 m²
Solving for y, we get:
y = (2*0.45)/x
y = 0.9/x
Now, let's use the formula for the perimeter of a triangle:
Perimeter = a + b + c
where a, b, and c are the lengths of the three sides of the triangle.
Since we know that the perimeter is about 325 cm, we can assume that the three sides are close to each other in length. Let's assume that each side has a length of 325/3 = 108.33 cm.
Converting to meters, we get:
a = b = c = 108.33/100 = 1.0833 m
Now, we can use the formula for the area of a triangle again to solve for x:
Area = (base x height) / 2
0.45 = (x * 0.9/x) / 2
0.9 = x²
x = √0.9 = 0.9487 m
Therefore, the base of the triangle is approximately 0.9487 meters, and the height is approximately 0.9/0.9487 = 0.9487 meters.
So the triangle has sides of length 1.0833 meters and a base of length 0.9487 meters, which gives us a perimeter of approximately 3.215 meters (rounded to three decimal places).

You want to purchase a new car in 4 years and expect the car to cost $76,000. Your bank offers a plan with a guaranteed APR of 4.5if you make regular monthly deposits. How much should you deposit each month to end up with $76,000 in 4years?
Question content area bottom
Part 1
You should invest $
enter your response here each month.
- To purchase a new car in 4 years and expect the car to cost $76,000, you need to calculate how much money you need to deposit each month in a bank account that offers a guaranteed APR of 4.5%.
- You can use a formula called PMT to calculate the monthly deposit amount. PMT stands for payment and it is the amount of money you need to pay or deposit each period to achieve a certain future value.
- The formula for PMT is: PMT = ( FV * r) / [ ( (1+r)^n) - 1] where FV is the future value, r is the interest rate per period, and n is the number of periods.
- In your case, FV is $76,000, r is 0.045/12 (because the interest rate is 4.5% per year and there are 12 months in a year), and n is 4*12 (because you want to save for 4 years and there are 12 months in a year).
- Plugging these values into the formula, you get: PMT = (76000 * 0.00375) / [ ( (1+0.00375)^48) - 1] = 1449.72
- This means you should deposit $1449.72 each month to end up with $76,000 in 4 years.

Answer:
(- 2, - 4 )
Step-by-step explanation:
4x - 3y = = 4 → (1)
3x + 3y = - 18 → (2)
adding the equations term by term will eliminate y
(4x + 3x) + (- 3y + 3y) = 4 - 18
7x + 0 = - 14
7x = - 14 ( divide both sides by 7 )
x = - 2
substitute x = - 2 into either of the 2 equations and solve for y
substituting into (2)
3(- 2) + 3y = - 18
- 6 + 3y = - 18 ( add 6 to both sides )
3y = - 12 ( divide both sides by 3 )
y = - 4
solution is (- 2, - 4 )
Dingaka receives R12650R12650 when taking out a loan with an annual simple discount rate of 12,5%12,5%. The loan has to be repaid in eight months’ time. The amount that he has to repay is?
Dingaka took out a loan of R12650 with a simple annual discount rate of 12.5%. He has to repay R11595.83 in eight months, after deducting the simple discount of R1054.17.
To find the amount that Dingaka has to repay, we can use the formula for simple discount
Simple Discount = Principal * Rate * Time
Where Principal is the original amount borrowed, Rate is the annual simple discount rate, and Time is the time period in years.
We know that Dingaka received R12650 as the principal amount and the annual simple discount rate is 12.5%, which is equivalent to 0.125 as a decimal. The time period is 8/12 = 2/3 years, since the loan has to be repaid in eight months' time.
Plugging these values into the formula, we get
Simple Discount = 12650 * 0.125 * 2/3
= 12650 * 0.08333333
= 1054.166625
Therefore, the amount that Dingaka has to repay is the principal minus the simple discount, which is
Amount to Repay = Principal - Simple Discount
= 12650 - 1054.166625
= 11595.833375
So, Dingaka has to repay R11595.83 after eight months.

Explanation for problem 15
4 kings gives a probability of 4/52 = 1/13.
After the king is chosen, there are 52-1 = 51 cards left since we aren't replacing it. The probability of getting a queen on the second selection is 4/51
(1/13)*(4/51) = 4/663 is the probability of a king, then a queen, with no replacement. We arrive at choice C as the final answer.

The graph in this problem is not a function, as it contains vertically aligned points.
The domain and the range are given as follows:
Domain: -3 ≤ x ≤ 3.Range: 1 ≤ y ≤ 3.When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.
When we trace a vertical line through the circle, it would cross the circle at two points, meaning that the graph contains vertically aligned points, and thus, is not a function.

Using the above as a guide, we have the following equation
4/3 = 7/W = 12/9
So, we have
W * 12 = 7 * 9
Evaluate the products and divide both sides by 12
W = 21/4
Hence, the value of W is 21/4

cant be that hard but i didnt pay attention
∠ AFE is supplementary to ∠ AFB and the measure of ∠ AFE = 102⁰.
option A.
What is a supplementary?Supplementary angles are the two angles that sum up to 180 degrees.
That is, if the sum of two angles is equal to 180 degrees, then the two angles are supplementary.
From the given diagram we can form the following equation;
∠ AFE + ∠ AFB = 180 (supplementary angles or sum of angles on a straight line )
∠ AFE = 180 - ∠ AFB
∠ AFE = 180 - 78
∠ AFE = 102⁰.

Jake and Rafael are training for a bike race. Jake is a beginner and starts by riding up a hill with a 7.9° incline. Rafael is more experienced and rides up a hill with an 18.3° incline. If Jake and Rafael ride 100 ft., how much more horizontal distance did Jake cover. A.4.1 ft. B.9.6 ft. C.17.7 ft. D. 19.2 ft.
Answer:
We can use trigonometry to solve this problem. The horizontal distance covered by each rider can be found by multiplying the distance they rode by the cosine of the angle of incline. The difference between the two distances will be the amount by which Jake covered less distance than Rafael.
For Jake:
Horizontal distance = distance * cos(angle of incline)
Horizontal distance = 100 ft * cos(7.9°)
Horizontal distance = 100 ft * 0.9925
Horizontal distance = 99.25 ft
For Rafael:
Horizontal distance = distance * cos(angle of incline)
Horizontal distance = 100 ft * cos(18.3°)
Horizontal distance = 100 ft * 0.9475
Horizontal distance = 94.75 ft
Difference in horizontal distance = 99.25 ft - 94.75 ft
Difference in horizontal distance = 4.5 ft
Therefore, Jake covered 4.5 ft more horizontal distance than Rafael. The closest option is A. 4.1 ft, but that is not the exact answer.

According to the information, we can infer that the area of the triangle is: 19 1/4ft²
How to calculate the area of the triangle?To calculate the area of the triangle, we need to use the formula for the area of a triangle:
Area = (1/2) x base x heightwhere,
Base = 5 1/2 ftHeight = 7 ft.How to find the height of the triangle?To find the height of the triangle, we need to use the Pythagorean theorem, which relates the slant height, height, and half the base:
(slant height)^2 = (height)^2 + (1/2 base)^2Substituting the given values, we get:
(1/3)^2 = (7)^2 + (1/2 x 5 1/2)^2(1/9) = 49 + (15/4)(1/9) = (196/4 + 15/4)(1/9) = (211/4)Multiplying both sides by 36, we get:
4 = 844.44...So the height of the triangle is approximately 2.04 ft.
Now we can plug in the values for the base and height into the formula for the area:
Area = (1/2) x 5 1/2 x 7Area = 19.25 square feetArea = 19 1/4ft²Therefore, the area of the triangle is approximately 19.25 square feet.
