Annual Interest Rate: A = P+Prt
Solve for r.
Answer:
r = [tex]\frac{A-P}{Pt}[/tex]
Step-by-step explanation:
Step 1: Subtract P from both sides.
[tex]P+Prt-P=A-P[/tex] [tex]Prt= A - P[/tex]Step 2: Divide both sides by Pt.
[tex]\frac{Prt}{Pt} = \frac{A-P}{Pt}[/tex] [tex]r= \frac{A-P}{Pt}[/tex]1/3 (1632 + x) = 726 solve for x
pLS help please i beg i plea plssss
[tex] \frac{1}{3} (1632 + x) = 726[/tex]
[tex] \frac{1}{3} (x + 1632) = 726[/tex]
[tex] \frac{1(x + 1632)}{3} = 726[/tex]
[tex] \frac{x + 1632}{3} = 726[/tex]
[tex]3· \frac{x + 1632}{3} = 3·726[/tex]
[tex]x + 1632 = 3·726[/tex]
[tex]x + 1632 = 2178[/tex]
[tex]x + 1632 - 1632 = 2178 - 1632[/tex]
[tex]x =546[/tex]
So, the value of x is 546.

Answer:
What value of x is in the solution set of 3(x - 4) = 5x + 2?
Solution:
3(x - 4) = 5x + 2 [Given]
Using the distributive law of multiplication on LHS
3x - 12 = 5x + 2
By grouping the similar terms on either sides and solving for x, we get
3x - 5x = 2 + 12
- 2x = 14
Divide both sides by -2 (by division property of equality)
(- 2x/2 )= 14/2
-x = 7
Therefore, the value of x is -7.

What is simple interest?Simple interest is the amount of interest charged on a given principal at a given rate and for a given period of time.
We have,
P = Principal = $482
R = Rate = 5.5%
T = Time = 3 years
The formula for finding the simple interest is given:
SI = (P x R x T) / 100
The amount of interest from a $482 investment at 5.5% over 3 years:
= (482 x 5.5 x 3) / 100
= 7953 / 100
= 79.53
Thus,
The interest earned with an investment of $482 at a rate of 5.5% over 3 years is $79.53.

the diagram shows a prism whose cross-section is an equilateral triangle of lengths 10cm. the length of the prism is 20cm
Answer:
[tex]686.6 cm^2[/tex]
Step-by-step explanation:
From the volume we can find the surface area of one of the triangle sides, by dividing it by its height. You find out that the surface of the triangle face is [tex]\frac {866}{20}=43.3 cm^2[/tex]. Let's pick two of them since we have two side faces (one close to us in the image, one far away), for a total area of [tex]86.6 cm^2[/tex]. At this point we need to add the area of the rectangular faces, which are three rectangles of length 20 and height 10, for a grand total of [tex]3\times10\times20 = 600 cm^2[/tex].
Adding everything together, we get [tex]600+86.6 = 686.6 cm^2[/tex]

To help open up a wine bar, Jose borrowed money from a bank. He took out a personal, amortized loan for $49,000, at an interest rate of 6. 65%, with monthly payments for a term of 7 years
Using simple interest, it is found that the monthly payments are of $854.875.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
[tex]A(t) = A(0)(1 + rt)[/tex]
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.In this problem, the parameters are A(0) = 49000, r = 0.0665, t = 7, hence the total amount is of:
[tex]A(t) = A(0)(1 + rt)[/tex]
[tex]A(t) = 49000[1 + 0.0665(7)][/tex]
[tex]A(t) = 71809.5[/tex]
Payments over a period of 12 x 7 = 84 months, hence the monthly payments are of:

The equation given is y = -4.9x^2 + 19.8x + 58
It is of the form y = ax^2 + bx + c which is the standard form for quadratics.
We have,
a = -4.9b = 19.8c = 58Plug the first two values into the equation below
h = -b/(2a)
h = -19.8/(2*(-4.9))
h = 2.0204081632653
That value is approximate.
Rounding to the nearest whole number gets us roughly h = 2
Recall that (h,k) is the vertex of the parabola. In this case, it's the highest point. The cannonball reaches the highest point at roughly 2 seconds.
-----------------
Extra side notes:
To find the maximum height, plug the h value into the original equation. This will yield the value of k.To find the cannonball's flight time, plug in y = 0 and solve for x. Ignore the negative x solution.Please Help!!!!!!!!!!!!!!!!!!!!!

Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Leiff decides to buy his video game, with a price tag of $128, at this site because he knows that he will get the 15% discount when he checks out. Leiff pays 5. 3% sales tax on the discounted price and pays a shipping fee of $4. 75. What is the total of Leiff’s online purchase? a. $112. 84 b. $114. 57 c. $118. 82 d. $119. 32 Please select the best answer from the choices provided A B C D.
Answer:
yea what the other guy said
The total of Leiff’s online purchases will be $119.32.Option d is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.
Consequently, the video game's price is as follows:
(0.85 x 128) = $108.80.
Leif must contribute an additional 5.3% of the new price, so
(100 + 5.3) = 105.3% of the new price
= (1.053 x 108.8) = $114.57
Including the video game's shipping cost,
114.57 + 4.75 = $119.32
Thus, the total price is $119.32
