Jack has $500 in a bank account that will earn 3% interest every year. Diane has $100 in an investment account that will earn 12% every year. How many years will it take for Diane's account balance to overtake Jack’s?
Answer:
20 years
Step-by-step explanation:
A=500(1+.03)^20
$903
A=100(1+.12)^20
$964
It took her 20 years to overtake.
Answer:
Simple interest = NeverCompound interest = 19 years and 4 monthsStep-by-step explanation:
Jack
Initial amount = $500Interest rate = 3% = 0.03Yearly interest = 0.03*500 = $15
Diane
Initial amount = $100Interest rate = 12% = 0.12Yearly interest = 0.12*100 = $12
Diane's initial amount and yearly interest amount are both less than of Jack's.
It means her balance will never overtake Jack's.
=======================
It is not mentioned in the question but let's assume it is compound interest which is annually compounded.
Then after x years their balance will be:
Jack
500(1 + 0.03)^x = 500*1.03^xDiane
100(1 + 0.12)^x = 100*1.12^xSolve inequality below:
100*1.12^x ≥ 500*1.03^x(1.12/1.03)^x ≥ 51.087^x ≥ 5x log 1.087 ≥ log 5x ≥ log 5 / log 1.087x ≥ 19.29 years = 19 years and 4 monthsAn auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798

please help :(((((!!!
Answer/Step-by-step explanation:
1. x = 130 ° (corresponding angles theorem)
y = x (vertical angles theorem)
y = 130 (substitution)
Or
y = 130° (alternate exterior angle theorem)
2. x = 65° (corresponding angles theorem)
y = 180 - 65 (linear pair theorem)
y = 115°
3. x = 180 - 80 (linear pair theorem)
x = 100°
y = 80° (alternate exterior angle theorem)

5 customer entered a store over the course of 3 minutes At what rate were the customers entering the store in customer per minutes.
Answer:
1.67 people per minute
Step-by-step explanation:
it's a proportion, basically. 5/3 = x/1, solve and you get 1.67. BTW if only five people enter in the span of 3 minutes, then this store needs to invest in advertising more, because i've seen CVS's with a better ratio than that. and that's sad!

The fraction to represent the 2/5 divided by [tex]1\frac{7}{8}[/tex] is 16/75.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, 2/5 divided by [tex]1\frac{7}{8}[/tex] =15/8.
Here, 2/5 ÷ 15/8
When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction reversing its numerator and denominator is the first step in dividing fractions. Multiply the two numerators after that. Multiply the two denominators after that.
2/5 × 8/15
= 16/75
Therefore, the fraction is 16/75.

Wallpaper was applied to one rectangular wall of a large room. Width: 42 ft length:25.5 ft. If the total cost of the wallpaper was $771.12, what was the cost, in dollars, of the wallpaper per square foot?
Answer:
$825869.52
Step-by-step explanation:
Given that,
Width of the rectangle, b = 42 ft
Length of the rectangle, l = 25.5 ft
The area of a rectangle is given by :
A = lb
So,
A = 42 ft × 25.5 ft
A = 1071 ft²
The total cost of the wallpaper was $771.12 . So,
Cost = 1071 × 771.12
= $825869.52
So, the cost of wallpaper per square foot is equal to $825869.52.

If c varies directly as l and inversely as a, then which of the equations describe the relation among the three variables c, l and a?
A. c = k/al
B. c = kl/a
C. 1/c = ka/l
D. c = ka/l
If c varies directly as l and inversely as a, then which of the equations describe the relationship among the three variables c, l and a is [tex]\rm c = k \dfrac{l}{a}[/tex].
Given ;
c varies directly as l and inversely as a.
The following steps can be used to determine the equation that describes the relationship among the three variables c, l, and a:
Step 1 - According to the given data, 'c' is directly varying as 'l'.
[tex]\rm c\; \alpha \; l[/tex]
Step 2 - Also given in the data that 'c' is inversely varying with 'a'.
[tex]\rm c \; \alpha \; \dfrac{1}{a}[/tex]
Step 3 - Combine the expression obtained in steps 1 and 2, that is:
[tex]\rm c\;\alpha \; \dfrac{l}{a}[/tex]
Step 4 - The mathematical expression of the above conclusion is given by:
[tex]\rm c = k \dfrac{l}{a}[/tex]
where k is the proportionality constant.
So, the correct option is B).
