pls help me high paying reward.
Step-by-step explanation:
In a GP, there is a common ratio between the terms.
8 / (-16/5) = 8 * (-5/16) = -2.5
-20 / 8 = -2.5
We can see that every new term is -2.5 times bigger than the previous term.
Hence to find the next term,
we multiply -20 by -2.5:
(-20)(-2.5) = 50.
Hence 50 should go into the box.

50

Answer:
I think it is the value of this constant is called the coefficient of proportionality
Step-by-step explanation:
The value of this constant is called the coefficient of proportionality or proportionality constant. ... Equivalently one may write x = 1k ⋅ y; that is, x is directly proportional to y with proportionality constant 1k (= xy).
Cant figure it out pls help
5y = -3x + 7
y = -3/5x + 7/5
Parallel = same slope
y = -3/5x + b
3 = -3/5 + b, b = 18/5
Standard form: Ax + By = C
y = -3/5x + 18/5
-3/5x - y = -18/5
Multiply by -5
Solution: 3x + 5y = 18
Answer: Scale factor = 2
This is the same as writing [tex]\frac{2}{1}[/tex]
===============================================
Explanation:
Focus on the left sides of each triangle. They correspond to one another. Note how RS represents the first two letters of RST; while MN represents the first two letters of MNO. We can see the order matters.
To find the scale factor, we divide MN over RS to get
MN/RS = 6/3 = 2
Therefore, the sides of triangle MNO are 2 times longer compared to the sides of triangle RST.
------------------------
Extra info:
If you want to find x, then you would solve the following
MN/RS = ON/TS
6/3 = x/5.5
6*5.5 = 3x
33 = 3x
3x = 33
x = 33/3
x = 11
or we could simply multiply ST = 5.5 by the scale factor 2 getting 5.5*2 = 11, which is the length of segment ON.

Answer: Choice B
Point P is located at (-2, -1.8)
======================================================
Explanation:
Refer to the diagram below. I've added point Q (2, -3) that is directly below point M, and directly to the right of point N. Right triangle MQN forms with the 90 degree angle at point Q.
The distance from N to Q is 5 units. Count the spaces or apply subtraction and absolute value to find this.
1/5 of this distance is (1/5)*5 = 1. Starting at point N, move 1 unit to the right to arrive at point A(-2,-3). Point P is directly above this point A, such that point P is on line segment MN.
In other words, point P has x coordinate x = -2. So the answer must be choice B as this is the only answer choice that has its point with x coordinate -2.
--------------------
The distance from Q to M is 6 units. Taking 1/5 of this leads to (1/5)*6 = 1.2
Start at point Q and move 1.2 units up to arrive at point B(2,-1.8). This point is on the same horizontal level as point P. So points B and P have the same y coordinate y = -1.8
The x coordinate of P is the same as the x coordinate of A(-2,-3)
The y coordinate of P is the same as the y coordinate of B(2,-1.8)
So overall, point P is located at P(-2,-1.8).
Again refer to the diagram. It shows point P directly above point A, and it shows point P on the same level as point B.
The length of segment NP is exactly 1/5 that of the length of segment NM.
We can write that as
NP = (1/5)*NM
this is equivalent to
5*NP = NM
after multiplying both sides by 5

Step-by-step explanation:
Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below.
Answer:
1. $927
2. The ERROR in his expression is that he used 1.015 instead of using 0.015 (1.5%).
Step-by-step explanation:
1. Calculation for What is the correct amount Vince will pay back altogether
Using this formula
A = P + PRT
Where,
A represent Amount=?
P represent Principal =$900
R represent Rate of interest= 1.5%
T represent Time=2 years
Let plug in the formula
A = $900 + $900(0.015*2)
A = $900 + $900(0.03)
A = $900 + $27
A = $927
2. Explanation of the error in in Vince’s expression.
Based on the information given the expression he used which is 900 + 900(1.015 • 2) was correct but the ERROR in his EXPRESSION is that he incorrectly used 1.015 instead of using 0.015 (1.5%).
Therefore the correct amount Vince will pay back altogether will be $927 while the ERROR in his expression used 1.015 instead of using 0.015 (1.5%).

Aimee and Ben are purchasing a condominium and are financing $160,000. The mortgage is a 20 year 3/1 ARM with a cap structure of 1.5/10. What will their payments be for the first 3 years?
Answer:
$1169.45
Step-by-step explanation:
Using the formula:
[tex]P = L \Big( \dfrac{c(1+c)^n}{(1+c^n) -1} \Big)[/tex]
where;
Loan amount L = 160000
number of months (n) = 20 × 12 = 240
Lets assume that the interest rate per month c = 6.25% since it is not given.
i.e. (6.25/( 100*12) ) = 5.208 × 10⁻³
∴
[tex]P = 160000 * \dfrac{5.208 *10^{-3} (1+5.208 *10^{-3})^{240}}{(1+5.208 *10^{-3})^{240}-1}[/tex]
P = $1169.45
