How much interest (in dollars) will Alex receive after 2 years if he deposited $14,000 in the bank at 3.5% annual interest rate? Davit received $870 as an interest for money invested in Foreign Exchange Market three years ago. How much money did he invest, if the annual interest was 4%. For starting a new business, Arthur borrowed $23000 and calculated $3450 interest for five years. What annual interest was considered?
Answer:
a) Interest = $980
b) Principal = $7250
c) Interest rate = 3%
Step-by-step explanation:
a) For Alex
How much interest (in dollars) will Alex receive after 2 years if he deposited $14,000 in the bank at 3.5% annual interest rate?
The formula for Simple Interest = PRT
Where
P = Principal = $14,000
R = Interest rate = 3.5% = 0.035
T = Time = 2 years
I = $14,000 × 0.035 × 2
I = $980
b) For Davit
Davit received $870 as an interest for money invested in Foreign Exchange Market three years ago. How much money did he invest, if the annual interest was 4%
The formula for Simple Interest = PRT
Where
P = Principal = ?
R = Interest rate = 4% = 0.04
I = $870
T = 3 years
years
Solving for P
P = I/RT
P = $870/0.04 × 3
P = $870/0.12
P = $7250
c) For Arthur
. For starting a new business, Arthur borrowed $23000 and calculated $3450 interest for five years. What annual interest was considered?
The formula for Simple Interest = PRT
Where
P = Principal = $23,000
R = Interest rate = ?
I = $3450
T = 5 years
years
We are Solving for R
R = I/PT
R = $3450/$23,000× 5
R = 3450/115000
R = 0.03
Converting to percentage
= 0.03 × 100
= 3%
In a 400-metre hurdles race
the first hurdle is 45 m from the start
the last hurdle is 40 m from the finish
the rest of the hurdles are 35 m apart.
What is the total number of hurdles?
Answer:
11 hurdles
Step-by-step explanation:
First hurdle = 45 m from start
Last hurdle = 40 m from finish
Other hurdles = 35 m apart
Let h = number of hurdles 35 m apart
400 = 45 + 40 + 35h
400 = 85 + 35h
400 - 85 = 35h
315 = 35h
h = 315 / 35
h = 9
Total number of hurdles = First hurdle + Last hurdle + Other hurdles
= 1 + 1 + 9
= 11 hurdles
Total number of hurdles = 11

You've been saving your allowance to buy some new video games you head to the mall to do some shopping you say that two stores are having a big sale on video games GameWorld is selling for video games for $68.00 Best Bargains is selling 6 video games for $99.00 If you only want to buy one video game which store will give you the better deal explain.
Answer: Best Bargains will give a better deal at $16.50 per game.
Step-by-step explanation:
You did not mention the number of games GameWorld was selling for $68.00 and that number is 4.
GameWorld is selling 4 games for $68.00. They are therefore selling one game for:
= 68/4
= $17.00 per game
Best Bargains is selling 6 video games for $99. Each game is:
= 99/6
= $16.50 per games
Best Bargains will give a better deal at $16.50 per game.

For two days, your boss decides to double the amount you make. If on day 1, you make $70 dollars
and on day 2, you make $80 dollars , write an expression for the total commission you earn?
1.) 2(70+80)
2.) 2(2+80)
3.) 70(90+2)
4.) 80(2470)
Answer:
1 because you get 70 and 80 a day NORMALLY and the 2 indicates double so the 2 multiplies the 70 and 80.
Step-by-step explanation:because you get 70 and 80 a day NORMALLY and the 2 indicates double so the 2 multiplies the 70 and 80.

A prism with length of 3 units, height of 3 and one-fourth units, and width of 1 unit. What is the volume of the prism? whole-unit cubes fit inside the prism. quarter-cubic units fit inside the prism. The total volume of the prism is units3.
Answer:
[tex]9[/tex]
[tex]2[/tex]
[tex]9\dfrac{3}{4}\ \text{units}^3[/tex]
Step-by-step explanation:
l = Length of prism = 3 units
h = Height of prism = [tex]3\dfrac{1}{4}=\dfrac{13}{4}\ \text{units}[/tex]
w = Width of prism = 1 unit
Volume of a prism is given by
[tex]V=lwh\\\Rightarrow V=3\times 1\times \dfrac{13}{4}\\\Rightarrow V=9.75\ \text{units}^3=9\dfrac{3}{4}\ \text{units}^3[/tex]
The number of whole unit cubes that can fit inside the prism is [tex]9[/tex]
For quarter cubic units
[tex]\dfrac{9}{4}=2\dfrac{1}{4}[/tex]
The number of quarter cubic units that can fit inside the prism is [tex]2[/tex]
Total volume of the prism is [tex]9\dfrac{3}{4}\ \text{units}^3[/tex].

Step-by-step explanation:
Zach is 23 years old. Sax age is 3 years older than twice Maya's age. Let m represent Maya's age. Which equation can be used to solve Maya's age?
Step-by-step explanation:
Let Maya's age is m.
Sax age is 3 years older than twice Maya's age
Sax age = 2m +3
Zach age = 23 years
We need to find the equation that is used to solve Maya's age. ATQ,
2m + 3 = 23
If we solve,
2m = 23-3
2m = 20
m = 10
Hence, this is the required solution.

If x – 9 is a factor of x2 – 5x – 36, what is the other factor?
Answer: (x+4)(x−9)
Step-by-step explanation:
Answer:
(X - 9) is one factor
(X + 4) is the other factor
Step-by-step explanation:
You can factor polynomials with guess work or with polynomial division
To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.
In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)

Plz guys help me pass math
Question about financial application functions
Plz answer this last question on my test
Plz show all the working
God bless you brother or sister
Answer ASAP
Answer:
The monthly payment is $247.53
Step-by-step explanation:
We need to firstly calculate the total amount to be paid
We have this by using the compound interest formula;
A = I ( 1 + r/n)^nt
A is the total amount to be paid back
I is the amount borrowed which is $8,000
r is the interest rate = 3.6% = 0.036
n is the number of times in a year = 12 (monthly)
t is the number of years = 3
Substituting these values ;
A = 8000(1 + 0.036/12)^(12 * 3)
A = 8000(1 + 0.003)^36
A = 8000(1.003)^36
A = 8,910.94
The monthly payment is this amount divided by the number of months in 3 years which is 36
We have this as;
8,910.94/36 = $247.53

Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 7?
A.
It is the graph of y = x translated 7 units down.
B.
It is the graph of y = x translated 7 units to the right.
C.
It is the graph of y = x where the slope is increased by 7.
D.
It is the graph of y = x translated 7 units up.
Answer:
A
Step-by-step explanation:
The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).
Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.
Answer:
D. it is the graph of y=x translated 7 units up
Step-by-step explanation:
The equation is in the form of y=mx+b, b being the y-intercept of the line. Because b in this case is 7 and the slope is just one, the only transformation was that the graph was shifted 7 units up
