A mortgage broker charges $4000 plus 1.8% of the mortgage amount. What is the mortgage broker fee for a $309,000 mortgage?
Answers
The answer is 9,562. Thank you very much.
The mortgage broker fee for a $309,000 mortgage is calculated by multiplying the mortgage amount by 1.8% and then adding a fixed charge of $4000, resulting in a total fee of $9,562.
Explanation:The mortgage broker fee for a $309,000 mortgage can be calculated by taking 1.8% of the mortgage amount and adding the fixed charge of $4000. To find 1.8% of $309,000, we multiply 0.018 by 309,000.
0.018 \( \times \) $309,000 = $5,562.
Then we add the fixed charge:
$5,562 + $4,000 = $9,562.
So, the mortgage broker fee for a $309,000 mortgage is $9,562.

Convert to inches to solve and then convert back. The first solution is 1 foot 10 inches.
Step-by-step explanation:
To solve convert feet inches into inches by multiplying the number of feet by 12 and adding it to the inches. Then subtract and convert back.
For example: 5 feet is 5*12=60 inches. So 5 feet 7 inches is 60+7=67.
3 feet is 3*12=36 inches. So 3 feet 9 inches is 36+9=45 inches.
Subtract the two.
67-45= 22 inches.
22 inches is 12+10. 12 inches is 1 foot. This is 1 foot 10 inches.

y2: -5

Fill in the numbers for the equation and solve. -5 - (-9) is 4. 10 - 9 is 1. 4/1 is just simply 4. There. The slope is 4, but we're not done. We'll use one of the points as x and y. Point-slope form is in the form of y - y1 = m(x - x1). y1 is -9. Because that is a negative number, we will be adding, so that part is y + 9, which eliminates answer choices A and B. x1 is 9. The other part will be 4(x - 9). That eliminates answer choice C. That leaves D, with the problem in point-slope form being y + 9 = 4(x - 9). When you subtract 4x from both sides, subtract 9 to isolate the y, multiply -10 and 4 together to get -40, and subtract 5 from -40 to get -45, the equation becomes -4x + y = -45. You use the values of the second point to find the value on the x-side. There. The answer is D.

10.5
Answers
the sum of the three angles of a triangle is 180, so
50+2x+40+4x+8=180
6x++98=180
6x=82
x≈13.67
Final answer:
To find the value of x, we use the fact that the angles of a triangle sum up to 180 degrees. By setting an equation with the given angle measurements and solving for x, we find the value of x to be 13.67.
Explanation:
The student asks about determining the value of x in two congruent triangles, ABC and XYZ, given the measurements of the angles. If triangles are congruent, their corresponding angles are equal. Using the fact that the sum of the angles in a triangle is 180 degrees, and given Angle A is 50 degrees, Angle B is 2x+40 degrees, and Angle Z is 4x+8 degrees, we can set up an equation because Angle B corresponds to Angle Z in congruent triangles:
50 + (2x + 40) + (4x + 8) = 180
Combine like terms:
50 + 2x + 40 + 4x + 8 = 180
6x + 98 = 180
Subtract 98 from both sides:
6x = 82
Divide both sides by 6:
x = 13.67
Therefore, the value of x is 13.67.

C. f(x) = x^3 – x^2 – 12x
D. f(x) = x(x + 3)(x – 4)
Answers
Explanation:
You can find the zeroes of a polynomial function in factored form by setting each factor equal to zero and solve for [tex]x[/tex].
The polynomial function of answer A is not even factored, so we can rule that one out.
Lets set each one of the factors of answer B equal to zero, solve for [tex]x[/tex] and see what happens:
- [tex]x=0[/tex]
- [tex]x-3=0[/tex]
[tex]x=3[/tex]
- [tex]x+4=0[/tex]
[tex]x=-4[/tex]
As you can see, our zeroes are 0,3, and -4, so this is not the correct answer either.
The polynomial function of answer C is not even factored, so we can rule that one out as well.
Lets apply what we just learned to the factored polynomial of answer D:
- [tex]x=0[/tex]
- [tex]x+3=0[/tex]
[tex]x=-3[/tex]
- [tex]x-4=0[/tex]
[tex]x=4[/tex]
This time our zeroes are, 0, -3, and 4; therefore we can conclude that D is the correct answer.

The length of the rectangle is 10 cm and the width is 11 cm. Using the Pythagorean theorem, the length of the diagonal can be calculated to be √221 cm.
Explanation:
The length of the rectangle is 10 cm and the width is 11 cm.
To find the length of the diagonal, we can use the Pythagorean theorem:
Diagonal2 = Length2 + Width2
Diagonal = √(102 + 112) = √(100 + 121) = √221 cm.
The length of the rectangle is 10 cm and the width is 11 cm. Using the Pythagorean theorem, the length of the diagonal can be calculated to be √221 cm.
a flyer on a reconnaissance flight has 4 hours for a round trip. his blade can fly 200 mph in still air. he flies out from his base against a 20 mph wind and immediately returns to his base, flying with the same wind. how many hours did he take for his fight out?
Answers
When flying against the wind, the effective plane speed is 200 - 10 = 180 mph.
Let d = the distance (miles) from his base to the destination.
The time (hours) to travel with the wind is
t₁ = d/220
The time (hours) to travel against the wind is
t₂ = d/180
The total time taken is 4 hours, therefore
t₁ + t₂ = 4
d/220 + d/180 = 4
d(1/220 + 1/180) = 4
0.010101d = 4
d = 396 miles
Therefore
t₁ = 396/220 = 1.8 hours = 1 hour, 48 minutes (floght in)
t₂ = 396/180 = 2.2 hours = 2 hours, 12 minutes (flight out)

A company need to package hazardous chemicals in special plastic rectangular prism containers that had 80 cubic feet. Find the whole number dimensions of the container that would use the least amount of plastic.
Answers
the cube is a prism rectangular with minimum surface area
then
Volume cube=b³=80-------------> b=4.31 ft
the problem is asking me for a whole number
therefore
b=4 ft------------> I assume a rectangular prism of square base
V=b²*h--------------> h=V/b²=80/4²=5 ft
the answer is 4 ft x 4 ft x 5 ft number dimensions of the container
To package hazardous chemicals in special plastic containers the dimensions of the container should be 4 × 4 × 5 feet.
A rectangular prism with a volume of 80 cubic feet needs to be designed to use the least amount of plastic. To do this, we need to find the dimensions (length, width, height) that, while maintaining the given volume, result in the minimum surface area.
The volume of a rectangular prism is given by:
Volume = length × width × height
For our case: length × width × height = 80 cubic feet
To minimize the surface area, the dimensions should be close to a cube as this shape has the smallest surface area-to-volume ratio. We will seek integer dimensions. The formula for the surface area (SA) of a rectangular prism is:
SA = 2(length × width + width × height + height × length)
We start by considering potential combinations of whole numbers whose product is 80:
1 × 1 × 801 × 2 × 401 × 4 × 201 × 5 × 161 × 8 × 102 × 2 × 202 × 4 × 102 × 5 × 84 × 4 × 5Calculating the surface area for each configuration:
1 × 1 × 80: SA = 2(1×1 + 1×80 + 80×1) = 2(1 + 80 + 80) = 322 sq. feet1 × 2 × 40: SA = 2(1×2 + 2×40 + 40×1) = 2(2 + 80 + 40) = 244 sq. feet1 × 4 × 20: SA = 2(1×4 + 4×20 + 20×1) = 2(4 + 80 + 20) = 208 sq. feet1 × 5 × 16: SA = 2(1×5 + 5×16 + 16×1) = 2(5 + 80 + 16) = 202 sq. feet1 × 8 × 10: SA = 2(1×8 + 8×10 + 10×1) = 2(8 + 80 + 10) = 196 sq. feet2 × 2 × 20: SA = 2(2×2 + 2×20 + 20×2) = 2(4 + 40 + 40) = 168 sq. feet2 × 4 × 10: SA = 2(2×4 + 4×10 + 10×2) = 2(8 + 40 + 20) = 136 sq. feet2 × 5 × 8: SA = 2(2×5 + 5×8 + 8×2) = 2(10 + 40 + 16) = 132 sq. feet4 × 4 × 5: SA = 2(4×4 + 4×5 + 5×4) = 2(16 + 20 + 20) = 112 sq. feetThus, the dimensions 4 × 4 × 5 feet are the ones that use the least amount of plastic, giving a surface area of 112 sq. feet.

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 6/5 .
What is the volume of the dilated prism?
Enter your answer, as a decimal, in the box.
Answers
The volume would be:
Volume of the prism(without dilated) = (area of the base) * (height)
Since,
Area of base = 5[tex]ft^{2}[/tex]
Height of the prism = 10f
Volume(without dilated) = 5*10 = 50[tex]ft^{3}[/tex]
Now let us apply the dilated factor! For that you need to multiply for factor with the volume of the prism without dilation.
Volume of the dilated prism = [tex]d^{3}[/tex] * (Volume of the prism without dilation)
Where d = dilated factor. Therefore,
[tex]v = (\frac{6}{5} )^{3} * 50[/tex]
v = 86.4[tex]ft^{3}[/tex]
So the correct answer: 86.4[tex]ft^{3}[/tex]

Final answer:
The radius to the nearest hundredth is 1.38
Explanation:
To find the radius of a cone with a given height and volume, use the formula [tex]V = 1/3 * \pi * r^2 * h[/tex], where V is the volume, r is the radius, and h is the height.
In this case, the volume is given as 12 in^3 and the height is given as 3 in.
Substituting these values into the formula:
[tex]12 = 1/3 * \pi * r^2 * 3[/tex]
Multiply both sides of the equation by 3:
[tex]36 = \pi * r^2 * 3[/tex]
Divide both sides of the equation by 3π:
[tex]12/\pi = r^2[/tex]
Take the square root of both sides of the equation:
[tex]r = \sqrt{(12/\pi )[/tex]
