The total amount that we need to pay back after the end of 3 years with principal amount as $ 680 and simple interest as 3.94 % will be $ 760.376.
We are given that:
Principal amount = P = $ 680
Time period = t = 3 years
Simple interest rate = r = 3.94 %
We know that, the formula for simple interest is given by:
SI = P × r × t
SI = 680 × 3.94 % × 3
SI = 80.376
Amount will become:
Amount = $ 680 + $ 80.376
Amount = $ 760.376
Therefore, we get that, the total amount that we need to pay back after the end of 3 years with principal amount as $ 680 and simple interest as 3.94 % will be $ 760.376.

Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms. Which are the terms Misha should combine? 3x – 2x and –8 – 7 3x – 2x and 8 – 7 3x – 2x + 4x and –6 – 8 – 7 3x – 2x – 6 and 4x – 8 – 7
Step-by-step explanation:
The given equation is : 3x-2(x+3)=4(x-2)-73x−2(x+3)=4(x−2)−7
On solving this equation and applying the distributive property, we have
⇒3x-2x-6=4x-8-73x−2x−6=4x−8−7

The equation y=6.88x-199 models the number of visitors at a pool,y, and the air temperature in degrees there are 426 visitors at the pool one hot day what is the expected air temperature on that da round your answer to the nearest degree
Answer:
[tex]\approx 91^\circ[/tex]
Step-by-step explanation:
The given equation to represent the model for the relationship between [tex]x[/tex] and [tex]y[/tex].
[tex]y=6.88x-199[/tex]
[tex]x[/tex] represents the air temperature in degrees and
[tex]y[/tex] represents the number of visitors at a pool.
Also given that number of visitors at the pool on a particular day is 426.
To find:
The expected air temperature as per the number of visitors.
Solution:
Here, we are given a linear equation to represent the relation between two variables.
Value of one variable is given and we have to find the value of other variable.
i.e. we are given that:
[tex]y=426[/tex] and we have to find the value of [tex]x[/tex].
Let us put the value in the equation:
[tex]426=6.88x-199\\\Rightarrow 6.88x = 426 + 199\\\Rightarrow x = \dfrac{625}{6.88}\\\Rightarrow \bold{x \approx 91^\circ}[/tex]

What is the result of isolating x² in the equation below?
(x+1)² + (y-8)² = 9
OA. x²=-y²-2x+16y-56
OB. x² = y² +2x+16y+56
C. x = -² -56
D. * = y² +56
The required result of the identity is [tex]x^{2} =-y^{2}-2x+16y-56[/tex].
To isolate the algebraic expression given below we need to simplify it and then make [tex]x^{2}[/tex] the subject of the equation,
For that we must know the identity [tex](a+b)^{2}=a^{2}+2ab+b^{2}[/tex].
We will break the given equation on the basis of the given identity.
Now, [tex](x+1)^{2} +(y-8)^{2}=9\\[/tex]
⇒[tex]x^{2} +2x+1+y^{2}-16y+64=9\\[/tex]
⇒ [tex]x^{2} =-y^{2}-2x+16y-56[/tex]
So, the required result of isolating the above given equation is as above.

y = x

Answer:
C. x - y = 0
Step-by-step explanation:
First find write the equation in slope-intercept form, then rewrite to convert to standard form as Ax + By = C.
Equation in Slope-intercept form:
Find m and b
m = rise/run = 1/1 = 1
b = y-intercept = 0 (where the line intercepts the y-axis)
Substitute m = 1, and b = 0 into y = mx + b
Thus:
y = (1)(x) + 0
y = x
Rewrite to convert to standard form.
Thus, the equation in standard form would be:
x - y = 0

The three angles in a triangle are in the ratio 1:3:5. Find the angles
Answer:
1:3:5
20:60:100
Step-by-step explanation:
angles in a triangle add up to 180
so we add 1,3 and 5 to get 9
to find out how much 1 part is worth we do 180÷9 to get 20
so 1 part=20
so we we do:
20x1=20
20x3=60
20x5=100
Answer:
30:60:100
Step-by-step explanation:
angles of triangle =180°
sum of ratios
1+3+5=9
finding for the first one which is one
1/9×180°=20°
finding for the second one which is three
3/9×180°=60°
finding for the third one which is five
5/9×180=100°
adding all the angles
20°+60°+100°=180°
5/8 and 3/4 I need an answer pleaseee
I'm not sure what you mean but I'll provide both.
5/8 + 3/4
11/8 or 1 3/8.
The common denominator of 5/8 and 3/4 is 8. 3/4 with a denominator of 8 would be 6/8.
5/8 + 6/8 = 11/8 or 1 3/8.
5/8 × 3/4
15/32.
Multiply the numerator by the numerator and the denominator by the denominator.
5 times 3 is 15 and 8 times 4 is 32.
So you get 15/32. This cannot be simplified.

Every month, Veronica deposits $230 in an account with an interest rate of 6% compounded monthly. How much money will she have in the account at the end of the first 5 years? (Round to the nearest cent. Do not enter the $ sign.)
Answer:
Veronica will have $310.04 at the end of first five years.
Step-by-step explanation:
Principal Amount P = $230
Interest Rate r = 6%
Time t = 5 years
Compounded monthly n = 12
We need to find the future amount (A)
The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values and finding A
[tex]A=P(1+\frac{r}{n})^{nt}\\A=230(1+\frac{0.06}{12})^{5*12}\\A=230(1+0.005)^{60}\\A=230(1.005)^{60}\\A=230(1.348)\\A=310.04[/tex]
So, Veronica will have $310.04 at the end of first five years.

Find the sample variance and standard deviation
19,12,6,7,11
Thank you
Answer:
Variance: 26.5
Standard Deviation: 5.1478150704935
Step-by-step explanation:
First, Add up all of the numbers: 6 + 7 + 11 + 12 + 19 = 55
Square the total, and then divided the number of items in the data set55 x 55 = 3025
3025 / 5 = 605
Take your set of original numbers from step 1, squared them individually this time, and added them all up:(6 x 6) + (7 x 7) + (11 x 11) + (12 x 12) + (19 x 19) = 711
Subtract the amount in step 2 from the amount in step 3:711 - 605 = 106
Subtract 1 from the number of items in my data set:5 - 1 = 4
Divide the number in step 4 by the number in step 5:106 / 4 = 26.5
Finally, take the square root of the number from step 6 (the variance),
√(26.5) = 5.1478150704935

Remember, plug into point-slope, y - y, = m(x - x,), then solve down I
Passes through (7, 4) with a slope of -3
The slope-intercept equation of the given line is 3x + y = 25
Slope-intercept is one of the special forms of linear equations where we can find the slope-intercept of any point with its coordinates and its slope.
The line is passing through the point(x₁,y₁) = (7,4)
The slope of the line line(m) = -3
Slope-intercept equation
y-y₁ = m( x- x₁)
Where (x₁,y₁) is (7,4) and Slope,m is -3
Let us substitute these values in the slope-intercept equation, It becomes
y - 4 = -3(x - 7)
y - 4 = -3x + 21
3x + y = 21 + 4
3x + y = 25

A model rocket is launched with an initial upward velocity of 156ft/s . The rocket's height h (in feet) after seconds is given by the following. h= 156t-16t^2
The values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
How to determine the values of t for which the rocket's height is 60?The function is given as:
h = 156t - 16t^2
When the height is 60 feet, we have:
156t - 16t^2 = 60
Rewrite as:
16t^2 - 156t + 60 = 0
Divide through the equation by 4
4t^2 - 39t + 15 = 0
Next, we solve the equation using a graphing calculator
From the graphing calculator, we have:
t = 0.40 and t = 9.35
Hence, the values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
