Total of fees: 1,000 + 4,900 = 5,900
You are told the APR is the total fees divided by the amount financed, so divide the total fees by the amount financed:
5,900 / 83,098.59 = 0.71
0.71 x 100 = 7.1% APR.

Rameen’s heating bill is $5.42 per month plus $1.08 per therm. How many therms can Rameen use if he wants his heating bill to be a maximum of $87.50? Write the solution in interval notation.
Write and solve an inequality:
Total(t) = $5.42 + ($1.08/therm)(t) ≤ $87.50.
First, subtract $5.42 from $87.50: then ($1.08/therm)(t) ≤ $82.08
Next, divide both sides by $1.08 per therm:
t ≤ ($82.08) / ($1.08/therm) = 76 therms (maximum). Thus, Rameen's usage could be [0,76] (therms).
Answer:
[0,76]
Step-by-step explanation:
Step 1. Read the problem.
Step 2. Identify what you are looking for.
the number of therms Rameen can buy
Step 3. Name what you are looking for. Choose a variable to represent that quantity.
Let t= the number of therms.
Step 4. Translate. Write a sentence that gives the information to find it. Translate into an inequality.
$5.42 plus $1.08 times the number of therms is less than or equal to $87.50.
5.42+1.08t≤87.50
Step 5. Solve the inequality.
1.08tt≤82.08≤76
Step 6. Check the answer in the problem and make sure it makes sense.
Yes, 5.42+1.08(76)=87.50.
Step 7. Answer the question with a complete sentence.
Rameen can buy no more than 76 therms if he wants his heating bill to be a maximum of $87.50.
Since it is not possible to buy a negative number of therms, the lest number of therms Rameen can buy is 0.
In interval notation, the amount of therms Rameen can buy is [0,76].
The longest side of an acute triangle measures 30inches. The two remaining sides are congruent, but their length is unknown. What is the smallest possible perimeter of the triangle, rounded out the nearest hundredth
The two short sides must be longer than those required in an isosceles right triangle. The ratio of side length to hypotenuse length in a 45°-45°-90° triangle is 1 : √2. So, such a triangle requires side lengths of 30/√2 ≈ 21.213 inches. Its perimeter will be about
... (30 +21.213 +21.213) in = 72.426 in
Since the perimeter needs to be slightly longer than that for the triangle to be acute, the smallest possible perimeter is ...

1) copper has density of 8.92 g/cm^3. How many milliliters of water would be displaced if 46kg of copper granules were poured into a barrel filled with water?
2) If the density of water is 1.00 g/mL, will the substances above float or sink in the water??
Answer:
1) Volume of water displaced = 5.16 L
2) Copper sinks in water.
Explanation:
1) Density of copper = 8.92[tex]g/cm^3[/tex]
Mass of copper = 46 kg = 46000 g
We know that, Density = Mass / volume
So, Volume = Mass/ density
Volume of copper = 46000/8.92 = 5156.95 [tex]cm^3[/tex]
Since the density of copper 8.92[tex]g/cm^3[/tex] is greater than density of water 1[tex]g/cm^3[/tex], the copper immerses in water. Since it immerses it will displace a volume of water which is equal to the volume of copper.
So volume of water displaced = volume of copper = 5156.95 [tex]cm^3[/tex] =5.16 L of water
2) Since the density of copper 8.92[tex]g/cm^3[/tex] is greater than density of water 1[tex]g/cm^3[/tex], the copper immerses in water. So copper sink in water.

Which inequality is equivalent to -m ≥ 15?
A. m ≥ 15
B. m ≥ -15
C. m ≤ -15
D. m ≤ 15
Answer:
c
Step-by-step explanation:
The inequality equivalent to -m ≥ 15 is m ≤ -15, achieved by multiplying both sides of the inequality by -1, which reverses the inequality symbol. So the correct answer is C. m ≤ -15.
The question asks which inequality is equivalent to the inequality -m ">≥ 15. To find the equivalent inequality where m is positive, we need to multiply or divide both sides of the inequality by -1, remembering that doing so reverses the inequality symbol. Therefore, multiplying both sides by -1 gives m ≤ -15, which means that the inequality that is equivalent to -m ≥ 15 is m ≤ -15.
So the correct answer is C. m ≤ -15.

A) We substitute the values for a ,b , c and d in the given equation.[tex]\frac{6}{3} +4^2 (5) \\= 2+80\\=82[/tex]
Hence option c. 82 is the answer.
2) The product 6(-3)
Since positive x negative gives negative
we get -(6x3) = -18
Option A is the answer.
3) For this we have to find cube of a fraction with numerator 4 and denominator 7
We find cube of numerator first = 4x4x4 =64
Cube of denominator = 7x7x7 = 343
Hence cube of fraction = 64/343
Option D
Given: C∉ BD ,△ABC D∈ ray BC ,AB=AC=BC Prove: BD>DA>AB
Triangle ABC is equilateral, because AB=BC=AC=a. Then
m∠A=m∠B=m∠C=60°.
Let point D lie on the ray BC to the right from points B and C and let CD=x. Then BD=a+x, AB=a.
Consider triangle ACD. In this triangle, m∠ACD=180°-m∠ACB=180°-60°=120°.
By the cosine theorem,
[tex]AD^2=AC^2+CD^2-2\cdot AC\cdot CD\cdot \cos \angle ACD,\\\\AD^2=a^2+x^2-2\cdot a\cdot x\cdot \cos 120^{\circ},\\\\AD^2=a^2+x^2+ax,\\\\AD=\sqrt{a^2+x^2+ax}.[/tex]
Since [tex]a^2+x^2+ax=a^2+x^2+ax+ax-ax=(a+x)^2-ax,[/tex] then
[tex]AD^2=(a+x)^2-ax<(a+x)^2=BD^2\Rightarrow AD<BD[/tex]
and
[tex]AD^2=a^2+x^2+ax>a^2=AB^2\Rightarrow AD>AB.[/tex]
Therefore, you get double inequality
[tex]AB<AD<BD[/tex] or [tex]BD>AD>AB.[/tex]

A company produces metal slabs for industrial use. the slabs come in 3 thicknesses: 5in, 10in, and 15in. the weights of each thickness for each metal are given below. metal 1: 150lbs, 300lbs, 600lbs metal 2: 130lbs, 260lbs, 390lbs metal 3: 310lbs, 620lbs, 930lbs metal 4: 140lbs, 280lbs, 420lbs for which of the metals is weight not proportional to thickness
Given slabs thicknesses 5in, 10in, and 15in.
Therefore, ratio of thicknesses in simplest form would be 1:2:3.
Metal 1 thicknesses = 150lbs, 300lbs, 600lbs
Dividing by 150, we get ratio of Metal 1 thicknesses = 1:2:4.
Metal 2 thicknesses = 130lbs, 260lbs, 390lbs.
Dividing by 130, we get ratio of Metal 2 thicknesses = 1:2:3.
Metal 3 thicknesses = 310lbs, 620lbs, 930lbs.
Dividing by 310, we get ratio of Metal 3 thicknesses = 1:2:3.
Metal 4 thicknesses = 140lbs, 280lbs, 420lbs.
Dividing by 140, we get ratio of Metal 4 thicknesses = 1:2:3.
We can see the ratios of thicknesses of Metal 1 are 1:2:4 but it should be 1:2:3.
Therefore, Metal 1 weight is not proportional to thickness.
Answer:
Weights of metal 1 is not proportional to thickness.
Step-by-step explanation:
We have been given 3 thicknesses of metal slabs and the weights of each thickness for each metal. We are asked to find out which of the metals weight is not proportional to thickness.
We can see that the thicknesses of slabs are first three multiples of 5 that is 5 inches, 10 inches and 15 inches.
Now let us see which of the metals have not their weights proportional to their thicknesses.
In our first option we can see that 300 is 2 times 150 and 600 is 4 times 150 which is not proportional to thickness. In order to metal 1's weight to be proportional with it's thickness it should be 450 lbs instead of 600.
Our second metal's weight is proportional to it's thickness as 130, 260 and 390 are 3 first consecutive multiples of 130.
Our third and fourth metal's weights are also proportional to their thicknesses.
Therefore, metal 1's weight is not proportional to thickness.

O It crosses the x-axis at e.
O It crosses the y-axis at e.
O It passes through the point (1,e).
O It passes through the point (e,1).
The function f(x) = e^x never crosses the x-axis and crosses the y-axis at point (0,1). It does not pass through the point (e,1), but it does pass through the point (1,e). Hence, the correct statement is 'It passes through the point (1,e)'.
Explanation:The function f(x) = e^x is an exponential function where 'e' is Euler's number, approximately equal to 2.71828. Its graph has distinctive traits which are related to the options provided.
The statements 'It crosses the x-axis at e' and 'It crosses the y-axis at e' are incorrect because the graph of f(x) = e^x never crosses the x-axis, and it crosses the y-axis at the point (0,1), not e.
The statement 'It passes through the point (e,1)' is also incorrect. This function, f(x) = e^x, will pass through the point (1,e), not (e,1). Hence, the option 'It passes through the point (1,e)' is the true statement about the graph of the function.

First Plot the coordinates in the Cartesian plane. Then join all the points. Now you should get a graph as the graph shown in "red lines" in the attachment.
To make it easier we add another point in the graph as "E(2,3)". Now we have two shapes, one is a rectangle ABED and the other is a triangle BEC. Addition of these to makes the ABCD quadrilateral.
Before finding the areas we need to find the lengths of each side.
AB=3-(-1)=4
AD=BE=2-(-4)=6
EC=4-3=1
Area of ABED rectangle = AB*AD
=[tex]4*6[/tex]
=[tex]24[/tex]
Area of the BEC triangle= [tex]\frac{1}{2}[/tex]*BE*EC
=[tex]\frac{1}{2} *6*1[/tex]
=[tex]3[/tex]
Therefore, total area of the quadrilateral = [tex]24+3[/tex]

(8)
Angles on the side of a straight line adds up to 180°
Therefore we can write the sum of all the angles as;
[tex]x+4x+20=180[/tex]
Then you can solve the equation to find the [tex]x[/tex] as follows.
[tex]5x+20=180[/tex]
