Last year, Frank opened an investment account with $7400. At the end of the year, the amount in the account had increased by 21%.
a) (121/100) × $7400
b) $8954
What is investment account?Stocks, bonds, funds, and other securities are kept in investment accounts in addition to cash. An important distinction between a bank account and an investment account is that the value of the assets in an investment account might vary, and even go down.
Savings may also refer to investing money in things like bank time accounts. By purchasing assets that might improve in value, such as stocks, real estate, or shares in a mutual fund, you can invest some of your money with the goal of seeing it grow.
Given that,
Frank opened an investment account with $7400
At the end of the year, the amount in the account had increased by 21%
a) year end amount:
= [(100 + 21)/ 100] × $7400
= (121/100) × $7400
b) year-end amount in Frank's account:
= (121/100) × $7400

Last season the St. Paul High School basketball team won 15 games and lost 25 games. What percent of the games were won by the school?
Answer:
To find the percentage of games won by the school, you can divide the number of games won by the total number of games played, and then multiply by 100.
In this case, the school won 15 games and lost 25 games, for a total of 15 + 25 = 40 games played.
So, to find the percentage of games won, you would do:
(15 / 40) x 100 = 37.5%
So, the St. Paul High School basketball team won 37.5% of their games last season.

Write the equation of the line that is perpendicular to y=−13x+2 and passes through ( 2 , 8)
Considering the definition of perpendicular line, the equation of the line that is perpendicular to y=−13x+2 and passes through (2, 8) is y= 1/13x + 102/13.
What is a linear equationA linear equation o line can be expressed in the form y= mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin.Perpendicular linePerpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines, you get –1.
Equation of perpendicular line in this caseThe line is y= -13x +2
where:
the slope m is -13.the ordinate to the origin b is 2.Since you multiply the slopes of two perpendicular lines, you get –1. So:
-13 × slope perpendicular line= -1
slope perpendicular line= (-1)÷ (-13)
slope perpendicular line= 1/13
The line passes through the point (2, 8). Replacing the slope and the coordinates of the point in the expression of a line:
8= 1/13× (2) + b
8= 2/13 + b
8 - 2/13= b
102/13= b
Finally, the equation of the perpendicular line is y= 1/13x + 102/13.

esmeralda wants to open an account for her grandchildren that she will have $80,000 in after 20 years. how much must she deposit now into an account that yields 1.75% interest, compounded monthly so that she will have $80,000 for her grandkids at the end of 20 years? round to the nearest cent
Esmeralda must deposit $53,637.38 to have $80,000 in 20 years.
What is compound interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It refers to the interest on a deposit or loan that is calculated not only on the initial principal but also on the accumulated interest from previous periods.
To find out how much Esmeralda must deposit now in order to have $80,000 in 20 years, you can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value (what Esmeralda wants to have in 20 years)
P = the present value (what Esmeralda wants to deposit now)
r = the annual interest rate (1.75% in this case)
n = the number of compounding periods per year (monthly in this case)
t = the number of years (20 in this case)
By substituting the given values into the formula, we get:
80,000 = P(1 + 0.0175/12)^(12*20)
Solving for P:
P = 80,000 / (1 + 0.0175/12)^(12*20)
The present value of Esmeralda's deposit is $53,637.38, rounding to the nearest cent.
Hence, Esmeralda must deposit $53,637.38 to have $80,000 in 20 years.

(Give your answer rounded to one decimal place.)
The ideal congressional district size (Standard Divisor) in 1790 was 34437.33.
What is Standard divisor?The number of persons each House of Representatives seat represents is known as the "Standard Divisor" (SD). By dividing the total population of all the states by the total number of seats available for voting, the SD is determined. SD is calculated as Total U.S. Population / Total Number of Voting Seats.
The ratio of the entire population to the available seats (or other allocations) is known as the standard divisor. • The Hamilton system divides up any extra seats among the states with the largest fractional parts after allocating each state its lower quota initially.
Given,
population in 1790 was 3,615,920,
number of objects = 105
⇒ Standard divisor = total population / number of objects
⇒ Standard divisor = 3,615,920 / 105

What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
The given inequality is 5y≤10.
In a graph of an inequality, the symbols (<,>) are represented using a dotted line and the symbols (≤,≥) are represented using a straight line.
So, the graph of inequality 5y≤10 will have a straight line.
Now, writing the inequality 5y≤10 in slope-intercept form y = mx + b -
5y = 10
5y = 0x + 10
Substituting the values of x and y with origin (0,0) -
5(0) = 0(0) + 10
0 = 10
Putting the inequality symbol back -
0 ≤ 10
Since, 0 ≤ 10 is true hence the shaded region of graph will cover the origin.
On solving 5y = 10 -
y = 2
Hence the points of the inequality will be (0,2).
