Answer:
125, 100, 80,64,51.2,40.96...
Step-by-step explanation:
y=[tex]\frac{4}{5}[/tex]x
So let's work backwards!
[tex]\frac{5}{4}[/tex](80)
=100
Then...
[tex]\frac{5}{4}[/tex](100)
=125
Hope this helps! :D
Answer:
125, 100
Step-by-step explanation:
Perhaps the terms of your series are supposed to be ...
__, __, 80, 64, 51.2, 40.96, ...
The common ratio is 64/80 = 0.8, so the recursive relation is ...
t[n] = 0.8×t[n-1]
__
Solving for the previous term, we find ...
t[n]/0.8 = t[n-1] . . . . . . divide by 0.8
or ...
t[n-1] = 1.25×t[n] . . . . . rearrange
Then the term previous to 80 is 1.25×80 = 100.
And the term previous to 100 is 1.25×100 = 125.
The first two terms of the geometric sequence are 125 and 100.

Alec opened up a savings account with $2,500 and the account will earn 3.5% simple interest. How much money will he have in 15 years?
Answer:
3812.5
Step-by-step explanation:
2500 x 3.5% = 87.5 x 15 = 1312.5 + 2500 = 3812.5
The money will Alec have in 15 years with 3.5% simple interest is equal to 3812.5.
We have given that,
Alec opened up a savings account with $2,500 and the account will earn 3.5% simple interest.
What is the simple interest?Simple interest refers to the straightforward crediting of cash flows associated with some investment or deposit.
2500 x 3.5%
= 87.5 x 15
= 1312.5 + 2500
= 3812.5
Therefore we get the money will he have in 15 years is equal to 3812.5.

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

The value of output for value of input of 200 is,
⇒ y = 1025
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The table shows the outputs for several inputs.
Now, We can find the expression for the table as;
Take two points are (0, 25) and (1, 30)
Hence, The equation is,
y - 25 = (30 - 25) / (1 - 0) (x - 0)
y - 25 = 5x
y = 5x + 25
Hence, The value of output for value of input of 200 is,
y = 5 × 200 + 25
y = 1000 + 25
y = 1025
Thus, The value of output for value of input of 200 is,
⇒ y = 1025

WILL GIVE BRAINLIEST FOR RIGHT ANSWER! :)
Answer:65.8
Step-by-step explanation:
Now we have: 70 percent of 94 = 65.8
Question: What is 70 percent of 94?
We need to determine 70% of 94 now and the procedure explaining it as such
Step 1: In the given case Output Value is 94.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 94 = 100%.
Step 4: In the Same way, x = 70%.
Step 5: On dividing the pair of simple equations we got the equation as under
94 = 100% (1).
x = 70% (2).
(94%)/(x%) = 100/70
Step 6: Reciprocal of both the sides results in the following equation
x%/94% = 70/100
Step 7: Simplifying the above obtained equation further will tell what is 70% of 94
x = 65.8%
Therefore, 70% of 94 is 65.8

Answer:
1. 6 ft
2. 1 ft
3. 1/2 ft
Step-by-step explanation:
We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.
Area of a square = s² (where s is the side length)
If the finished quilt has an area of 36 ft² then the length of one side is:
⇒ s = √(36) = 6 ft
Side length of main design = 5 ft
Side length of finished quilt = 6 ft
6 - 5 = 1 ft
Therefore, the border increased the total length of each side by 1 ft
As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.
Therefore, the width of the border is 1/2 ft
**see attached diagram. Main design is shown in blue, border is shown in green**
3.72 divided by 10^4 which of these shows and explains the correct location of the decimal point when the expression is evaluated?
A 0.0000372 because 4 zeros are placed in font of the number when you divide by 10 to the fourth power
B 0.000372 because the decimal point moves 4 places to the left when you divide by 10 to the fourth power
C 37,200 because the decimal point moves for places to the right when you divide by 10 to the fourth power
D 3,720,00 because 4 zeros are placed after the number when you divide by 10 to the fourth power
Answer:
B
Step-by-step explanation:
This is the answer because when you move the decimal point 4 places to the LEFT( moving left is for dividing while moving right will be for multiplying, also this only works for exponents of 10) it will equal to 0.000372.

Answer:
-0.58
Step-by-step explanation:
The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.
I hope this helps and please mark me as brainliest!
Answer:
-0,56
Step-by-step explanation:
As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6
So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.
Another way of putting this is you must add 0.02.
For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02
First notch: -0.6 + 0.02 = -0.58
Answer: Second notch: -0.58 + 0.02 = -0,56

Solving forr
r=(3V
4π)⅓=(3·802
4·π)⅓≈5.76362m
Answer:
r = 5.8 meters
Step-by-step explanation:
The volume formula is V = (4/3)(pi)(r^3), where r is the radius.
Solving for r, we get first 3V = (4pi)(r^3), so that r^3 = (3V)/(4pi)
or in this case, r^3 = 3(802 m^3) / (4pi) = 191.5 meters^3
Taking the cube root of both sides yields r = 5.8 meters

jake buys a new car that costs $15,000 he borrowed from the bank with 3.5% compound interest per year. If it takes 7 years to pay off the loan, how much will he have paid for the car?
Answer:
NVM MY ANSWER IS WRONG ITS INTEREST NVM SRRY
Step-by-step explanation:
you can solve this by doing I=PRT
I=Interest (total which is
P= Principle ($15,000)
R= Rate (3.5% which turns to 0.35 bc you turn it into a decimal)
T= Time (7 years)
Once they are identified you mulitply them together:
(15,000)(0.35)(7)=36,750
