mark invested 125 he earned a simple interest of 3% per year on the initial investment if no money was added or removed from the investment what was the amount of interest mark received at the end of two years
Answer:
$7.50
Step-by-step explanation:
formula for simple interest:
I = prt
I = ($125)(0.03)(2)
I = $7.50
Answer:
You time 125 by 1.03 twice subtract 125 from that awnser to get the amount of money from interest 7.6125 is the awnser
Step-by-step explanation:
what does 2(3x − 7) + 18 = 10 equal
Answer:
x = 1
Step-by-step explanation:
We have an expression and are asked to find x perhaps?
2(3x - 7) + 18 = 10
To solve this, we need to get x alone.
Distribute :
(2(3x) - 2(7)) + 18 = 10
6x - 14 + 18
Add like terms :
6x + 4 = 10
Subtract 4 from both sides :
6x = 6
Divide 6 from both sides :
x = 1
Answer:
First you do 2x3 and then 2x7 that would be 6x and 14 so add 18 to 14 and that woukd be 32 so Try 32+6x... I would thnk i'm correct Can I also get Branliest..?

Step-by-step explanation:
In a game show, players play multiple rounds to score points. Each round has 3 times as many points available as the previous round.
Round 0 1 2 3 n
Points 25 75 225 675
Which equation shows the number of points available, p, in round n of the game show?
Answer:
[tex]p = 25(3)^n[/tex]
Step-by-step explanation:
Given
Round 0 1 2 3
Points 25 75 225 675
Required
Determine the equation
Let n = rounds and p = points.
So, we have:
[tex](n_1,p_1) = (0,25)[/tex]
[tex](n_2,p_2) = (1,75)[/tex]
[tex](n_2,p_2) = (3,225)[/tex]
The above shows a geometric progression.
So, we solve using
[tex]p = ab^n[/tex]
In [tex](n_1,p_1) = (0,25)[/tex]
n = 0 and p = 25
Substitute these values in [tex]p = ab^n[/tex]
[tex]25 = ab^0[/tex]
[tex]25 = a*1[/tex]
[tex]25 = a[/tex]
[tex]a = 25[/tex]
In [tex](n_2,p_2) = (1,75)[/tex]
n = 1 and p = 75
Substitute these values in [tex]p = ab^n[/tex]
[tex]75 = ab^1[/tex]
[tex]75 = ab[/tex]
Substitute 25 for a
[tex]75 = 25*b[/tex]
Make b the subject
[tex]b = \frac{75}{25}[/tex]
[tex]b = 3[/tex]
So, we have:
[tex]a = 25[/tex] and [tex]b = 3[/tex]
The equation [tex]p = ab^n[/tex] becomes
[tex]p = 25(3)^n[/tex]
Equation representing the number of points 'P' in 'n' games will be [tex]P=25(3)^{n}[/tex].
Explicit formula of the Geometric sequence:a, ar, ar², ar³........arⁿ
There is a common ratio of 'r' in each successive term to the
previous term.
Therefore, it's a geometric sequence.
Explicit formula of a geometric sequence is given by,[tex]T_n=ar^{n-1}[/tex] (For n ≥ 1)
Here, [tex]a=[/tex] First term
[tex]r=[/tex] Common ratio
[tex]n=[/tex] nth term
Given in the table,
Common ratio (r) of any successive term to the previous term,[tex]r=\frac{75}{25}=3[/tex]
First term of the sequence 'a' = 25Explicit formula of the sequence will be,
[tex]P=25(3)^{n}[/tex] [For n ≥ 0]
Therefore, equation representing the number of points 'P' in 'n' games will be [tex]P=25(3)^{n}[/tex].

please help(: ( 8th grade lesson)
Step-by-step explanation:
Since angle 1 is on a straight line and we know that angle 4 is 160, and a straight line has a sum of 180 degrees, simply subtract 160 from 180 to get angle 1.
Angle one would be 180-160 = 20
Since the sum of angles in a triangle is 180 and we already know 2 of them, angle 1 is 20 and angle 3 is 30, just add them together and then subtract that from 180. 20 + 30 = 50, and 180 - 50 = 130.
So in conclusion:
Angle 1 is: 20
Angle 2 is: 130

Answer:
0.6 inch
Step-by-step explanation:
The volume of a sphere is calculated through the equation,
V = 4πr³/3
Which means that the radius is calculated by the equation,
(3V/4π)^(1/3) = r
Substituting,
Sphere A, (3x30/4π)^(1/3) = r = 1.927 in
Sphere B, (3x10/4π)^(1/3) = r = 1.336 in
When we subtract the radius, we get an answer of 0.59 inch. Therefore, the answer to this item is approximately 0.6 inch.

Which fraction divided by 3/6 is equal to -9/10? A-9/20. B9/20. C-3/2. D9/40
Answer: -9/20 is equal to -9/10 when divided by 3/6 (1/2)
Step-by-step explanation:
Begin by reducing the fraction you're dividing with. In this case 3/6 can be reduced to 1.2, also known as 0.5 Beginning with -9/20, as it is the first answer option, we can put the problem into the following equation: -9/20 * 2/1 = -9/10.It is always good to verify all of your answer options are not possible answers. However, in a question like this, the math evenly works out in most cases, eliminating any other possible answer options.

Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100
[tex]=\frac{65}{100}*80*100\\\\= 65*80\\= 5200[/tex]
Amount paid for next 50 watches = (55% of 80) * 50
[tex]= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200[/tex]
Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125
[tex]= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500[/tex]
Amount received by the watch maker = 5200 + 2200 + 4500

A total of 150 tickets were sold for the annual concert. Student tickets were $4 and non-students $8. If the total revenue was $840, how many tickets of each type were sold ?
Answer:
x = 90
y = 60
Step-by-step explanation:
Let x = student
Let y = non-student
x + y = 150
4x + 8y = 840 <—— Use elimination/addition ethos for both equations
8 (x + y = 150)
-1 (4x + 8y = 840) <—— Let’s eliminate y
8x + 8y = 1200
+ -4x - 8y = -840
—————————————
4x = 360
x = 90
x + y = 150 <— substitute for x from above
90 + y = 150
- 90 = - 90 <— subtract from both sides
y = 60

Is (3,8) a solution to this system of equations? How do you know?
y=7x + 8
y=x + 1
Answer:
yes it is
Step-by-step explanation:
The point (3,8) is not a solution of system of equation. Explanation given below.
What is the system of equation?Simultaneous equations are any equations with the same number of unknowns that may be solved at the same time. The system of equations is a simultaneous equation.
Given system of equation,
y=7x + 8
y=x + 1
To find that the point (3,8) is a solution of system of equation,
we substitute the point to both of these equation and verify if that point is satisfying the equation or not.
In the first equation, x=3 and y =8
we get, 8 = 29
which is contradiction.
In the second equation ;
we get, 8 = 4.
Which is also contradiction.
Therefore, the equations do not have the solution (3 , 8).

Answer: m<C = 45, m<M = 50, m< B = 85.
Step-by-step explanation:
Adjacent angles on a line sum to 180 degrees.
m<C + m<M + m<B = 180. 45 + (8x+10) + (12x+25) = 180. Combine like terms. 80+ 20x =180. Subtract 89 from both sides. 20x = 100. Divide both sides by 20. X = 5. Substitute x back into the angle measures. m<C = 45, m<M = 50, m< B = 85.
