Answer:
Step-by-step explanation:
Given:
Simple Interest = $50
Principal Amount= $500
Rate of Interest = 9.5%
Find:
Time=?
The formula for Simple Interest is
I=PRT
{I=Simple Interest
P=Principal amount
R=Rate of Interest
T=Time}
To find out the time for the simple interest to get to $50:
Acc. to the formula T=I/PR
i.e., T=50/(500*9.5/100)
T=100*50/500*9.5
T=100/95
T=1.05 years
Therefore, it will take 1.05 years to get a simple interest of $50 at a rate of 9.5% for a principal amount of $500.

△DEF is an isosceles triangle. If m∠D = (3x + 5)° , m∠E = (4x − 15)° and m∠F = (2x + 10)° , what is the measure of one of the congruent base angles?
The measure of one of the congruent base angles is 65°.
How to illustrate the triangle?It's important to note that any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane. In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. A triangle has three sides, three angles and the sum of the angles equal 180°.
It should be noted that a triangle has 3 side, 3 angles and a sum of 180°.
In this situation, DEF is an isosceles triangle. If m∠D = (3x + 5)° , m∠E = (4x − 15)° and m∠F = (2x + 10)°.
The value will be illustrated thus:
3x + 5 + 4x - 15 + 2x + 10 = 180
Collect the like terms
9x = 180 - 5 + 15 - 10
9x = 180
x = 180 / 9
x = 20
The measure of one of the congruent base angles will be:

From a hot-air balloon, Justin measures a 34° angle of depression to a landmark
that's 1424 feet away, measuring horizontally. What's the balloon's vertical distance
above the ground? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
960.50 feet
Step-by-step explanation:
You want to know the height of a balloon if it is 1424 feet horizontally from a landmark at an angle of depression of 34°.
TangentThe geometry of the problem can be modeled as a right triangle with a base angle of 34°, the adjacent leg 1424 feet, and the opposite leg being the height of the balloon. The tangent relation tells us ...
Tan = Opposite/Adjacent
Opposite = Adjacent·Tan
height = (1424 feet)·tan(34°) ≈ 960.50 feet
The balloon's vertical distance from the ground is 960.50 feet.
__
Additional comment
If the angle is measured to the nearest degree, then the height of the balloon is somewhere between 943 feet and 979 feet. The only purpose served by reporting the distance to the nearest 0.01 foot is to see if you can use your calculator correctly.
To make that precision for the height meaningful, the angle would need to be measured with an error less than 0.00014°, about 1/2 arc-second. This is better resolution than the best surveying instruments offer, by a factor of about 30.

Additional comment
The "standard form" of a number is different by location. In the US, it is written with the decimal point to the right of the units digit. In other places, "standard form" has the decimal point to the right of the most-significant digit, and a power of ten as a multiplier.
You may recognize the ratio of the given numbers is 9:40, telling you these lengths are a multiple of the {9, 40, 41} Pythagorean triple. That is, the distance RQ is 41/40 times the distance RP.
Any spreadsheet or scientific or graphing calculator can do the necessary arithmetic using the numbers in "scientific notation" format. Spreadsheets, in particular, use E() to signify ×10^().

Find the perimeter of the triangle XYZ with verticles X (1, 3) , Y(-4, -1) and Z(4, -1). Round your answer to two decimal places
Answer:
The perimeter is approximately 6.40.
Step-by-step explanation:
To find the perimeter of a triangle with vertices X (1, 3), Y (-4, -1), and Z (4, -1), we can first find the distance between each pair of points using the distance formula.The distance between points X and Y is:
$d(X,Y) = \sqrt{((1 - (-4))^2 + (3 - (-1))^2)} = \sqrt{25 + 16} = \sqrt{41}$
The distance between points Y and Z is:$d(Y,Z) =
\sqrt{((-4 - 4)^2 + ((-1) - (-1))^2)} = \sqrt{0 + 0} = 0$
The distance between points X and Z is:
$d(X,Z) = \sqrt{((1 - 4)^2 + (3 - (-1))^2)} = \sqrt{9 + 16} = \sqrt{25}$
We can then find the perimeter of the triangle by adding up the lengths of the sides. In this case, the perimeter is $d(X,Y) + d(Y,Z) + d(X,Z) = \sqrt{41} + 0 + \sqrt{25} = \sqrt{41} + \sqrt{25} = 6.40\ldots$.
Rounded to two decimal places, the perimeter is approximately 6.40.
(50 points) Mariel and Sam Trent's savings account had a balance of $9,544 on May 1. The account earns interest at a rate of 5.25% compounded monthly until the end of August.
Answer:
$9,712.12 (nearest cent)
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ A=P\left(1+\frac{r}{n}\right)^{nt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]
Given:
P = $9,544r = 5.25% = 0.0525n = 12 (monthly)t = 4 months = 1/3 yearSubstitute the given values into the formula and solve for A:
[tex]\implies A=9544\left(1+\frac{0.0525}{12}\right)^{12 \cdot \frac{1}{3}}[/tex]
[tex]\implies A=9544\left(1.004375\right)^{4}[/tex]
[tex]\implies A=9544\left(1.017615179\right)[/tex]
[tex]\implies A=9712.119269[/tex]
The balance of the account at the end of August will be $9,712.12 (nearest cent).

slope = −9/4 in standard form
Answer: [tex]9x+4y=-20[/tex]
Step-by-step explanation:
Standard form is ax+by=c. What we can do is put the given point and slope into slope-intercept point, and then manipulate it to standard form.
[tex]y=-\frac{9}{4} x-5[/tex] [add both sides by [tex]\frac{9}{4} x[/tex]]
[tex]\frac{9}{4} x+y=-5[/tex] [multiply both sides by 4]
[tex]9x+4y=-20[/tex]
Therefore the standard form is [tex]9x+4y=-20[/tex].
