One of the four fundamental mathematical operations is addition. The length of the missing side is 6 yd.
What exactly is addition?
Addition is one of the four basic mathematical operations, along with subtraction, multiplication, and division. The total quantity or sum of two whole numbers is obtained by adding them together.
According to the question,
All the line intersecting at right angles . So,
The lines AB, CD, and EF are parallel in the diagram, we can write the length of AB as,
AB length = EF length - CD length

Valeria invested $770 in an account paying an interest rate of 53% compounded
monthly. Zoey invested $770 in an account paying an interest rate of 5%
compounded continuously. To the nearest dollar, how much money would Zoey have
in her account when Valeria's money has tripled in value?
4
Answer:
[tex]\$856.03[/tex]
Step-by-step explanation:
Continuous Compound Interest Formula:The Continuous Compound Interest Formula is derived from the Compound Interest Formula: [tex]A = P(1 + \frac{r}{n})^{nt}[/tex], as the number of times interest is applied, goes to infinity. Through some simple algebraic manipulation, we get the formula: [tex]A = Pe^{rt}[/tex] (e is known as Euler's Number and is notation for a constant value like [tex]\pi[/tex])
Calculating Time:Since Valeria invested 770 in an account with an interest of 53% paying monthly, we want to find how much time it takes to triple her money, and then plug that into Zoey's equation.
So let's generally solve for time in the equation:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
First divide by P
[tex]\frac{A}{P} = (1 + \frac{r}{n})^{nt}[/tex]
From here, it helps to take the base 10 log of both sides, so we can apply logarithmic properties, in this case we want to bring the exponent down.
[tex]log(\frac{A}{P}) = nt * log(1 + \frac{r}{n})[/tex]
Now from here' lets divide both sides by the log (the one on the right side) and "n" to give us:
[tex]\frac{log(\frac{A}{P})}{n * log(1 + \frac{r}{n})} = t[/tex]
Now whenever we need to calculate time, we simply need to plug in these values. We're given the following information from the problem:
[tex]P = 770\\r = 0.53\\n = 12\text{ compound monthly means 12 per year}\\A= 2,310 \text{ this is just 770 * 3, since we're looking for when Valeria's money triples}[/tex]
Plugging in the values we get:
[tex]\frac{log(\frac{2310}{770})}{12*log(1+\frac{0.53}{12}}=t[/tex]
Plugging this into a calculator, gives an approximate value of:
[tex]2.1183\approx t[/tex]
Calculating Zoey's Balance:From here we simply need to plug values into the continuous compound interest formula: [tex]A=Pe^{rt}[/tex]
We're given the following information:
[tex]A = 770\\r= 0.03\\[/tex]
and we know that:
[tex]t\approx 2.1183[/tex]
since we solved for that.
So now let's just plug values into the equation!
[tex]A\approx 770 * e^{0.05 * 2.1183}\\A \approx 856.03[/tex]
So now we have our solution!

Write your answer in scientific notation, and round to one decimal place. ______ pages
The maximum number of pages the report can have in scientific notation is equal to 2.0×10⁶ pages.
Scientific Notation is the expression in which numbers are written in the powers of 10 so that their expression can be used in calculation and also it makes calculation easy. To find the maximum number of pages the report can have, we need to divide the size of the USB drive, which is 4×10⁶ KB, by the size of each page, which is 2 KB/page. Doing this gives us:
4×10⁶ KB / 2 KB/page = 2×10⁶ pages

a) I don’t go to work tomorrow unless I feel better
b) I will buy this car if I’ll like it
c) I’ll tell when I hear from him
d) I’m not usually attending such par
Answer: D
Step-by-step explanation: It is D because the: "'m" in: "i'm" means: I am. The: 'I'm" is referring to you.
in C, the: "i'll" means: I will. After the: "tell", it doesn't make sense because it's not referring to someone. In between the: "tell" and "I", you should include: you. Overall, it should've sounded like: I'll tell you when I hear from him.
In B, the: "i'll" means I will. If you say in starting at this POS, It would sound: I will buy this car if I will like it. this does not make sense because instead of: i'll, you should replace it with: I.
In A, the: "don't" doesn't make sense because saying starting at a POS: I don't go to work tomorrow unless I feel better. You should replace the: "don't" with: won't.

Answer:
Suma= 80 + (4 × 40) + (4 × 20) + (4 × 10) + (4 × 5)
Suma= 80 + 160 + 80 + 40 + 20
Suma= 400
Step-by-step explanation:
The sum of the first five terms of the geometric progression is 1705.
To calculate the sum of the first five terms of a geometric progression, we need to determine the first term and the common ratio. Given that the third term is 80 and the ratio is 4, we can find these values.
In a geometric progression, each term is obtained by multiplying the previous term by the common ratio. Let's denote the first term as "a" and the common ratio as "r."
Given that the third term is 80, we can write the equation:
a * r² = 80
We are also given that the ratio is 4, so we have:
r = 4
Substituting this value of r into the equation, we get:
a * (4)² = 80
a * 16 = 80
16a = 80
a = 5
Now that we have determined the first term (a = 5) and the common ratio (r = 4), we can calculate the sum of the first five terms using the formula for the sum of a geometric series:
Sum = a * (1 - rⁿ) / (1 - r)
Plugging in the values, we have:
Sum = 5 * (1 - 4⁵) / (1 - 4)
Simplifying the calculation:
Sum = 5 * (-1023) / (-3)
Sum = 1705

A motorboat travels 192 kilometers in 3 hours going upstream and 360 kilometers in 4 hours going downstream. What is the rate in still water and the rate of the current
To find the rate in still water, we need to find the average speed of the boat. The total distance traveled by the boat is 192 + 360 = 552 kilometers. The total time taken is 3 + 4 = 7 hours.
So, the average speed of the boat is 552/7 = 78.857 km/hr.
To find the rate of the current, we need to find the difference in speed between the upstream and downstream journeys. The difference in speed is 360/4 - 192/3 = 90 - 64 = 26 km/hr.
So, the rate of the current is 26 km/hr.
Therefore, the rate in still water is 78.857 km/hr and the rate of the current is 26 km/hr.

To determine if the given points lie on the curve y = x², simply substitute the x-value of each point into the equation and compare y-values.
Point A
[tex]\boxed{\begin{aligned}x=\dfrac{3}{2} \implies y&=\left(\dfrac{3}{2} \right)^2\\\\y&=\dfrac{3^2}{2^2}\\\\y&=\dfrac{9}{4}\end{aligned}}[/tex]
As 9/4 ≠ 9/2, point A does not lie on the curve.
Point B
[tex]\boxed{\begin{aligned}x= -1\implies y&=\left(-1 \right)^2\\y&=1\end{aligned}}[/tex]
As 1 = 1, point B does lie on the curve.
Point C
[tex]\boxed{\begin{aligned}x=4 \implies y&=\left( 4\right)^2\\y&=16\end{aligned}}[/tex]
As 16 = 16, point C does lie on the curve.
Point D
[tex]\boxed{\begin{aligned}x=\dfrac{1}{2} \implies y&=\left(\dfrac{1}{2} \right)^2\\\\y&=\dfrac{1^2}{2^2}\\\\y&=\dfrac{1}{4}\end{aligned}}[/tex]
As 1/4 = 1/4, point D does lie on the curve.

The points (-7, r) and (-3, 14) lie on a line with slope 3. Find the missing coordinate r.
The value of the missing coordinate, r as required to be determined from the given information is; r = 2.
What is the value of the missing coordinate, r?It follows from the task content that the value of the missing coordinate, r is to be determined from the task content.
On this note, since the given points are; (-7, r) and (-3, 14) and the slope of the line through them is; 3.
It follows from the slope formula;
m = (y₂ - y₁) / (x₂ - x₁) that;
3 = ( 14 - r ) / ( -3 -(-7) )
-9 + 21 = 14 - r
r = 14 + 9 - 21
r = 2.
On this note, the required value of the missing coordinate, r is; 2.
