The amount Vicente needs to deposit now in order to have a balance of $20,000 in his savings account after 10 years is $15,384.62

What is simple interest?

The simple interest on the savings is determined as the deposit multiplied by the annual interest rate and the number of years that deposit would last in the account

I=PRT

I=simple interest

P=principal=deposit=unknown

R=annual simple interest=3%

T=number of years=10

A(amount in 10 years)=P+PRT

A=P(1+RT)

$20,000=P(1+3%*10)

$20,000=P*1.30

P=$20,000/1.30

P=$15,384.62

The number of adult tickets, that  were sold that day  at the movie theatre was 62

What are simultaneous equations?

Simultaneous equations are two or more equations that must be solved concurrently in order to derive the values of the unknown, the total sales, as well as the total number of tickets sold, can be modeled into equations as below:

let x be the number of adult tickets

let y be the number of children's tickets

9x+5.90y=1000.60....... equation 1

x+y=137.................. equation 2

solve for y in equation 2

y=137-x

substitute for y in equation 1

9x+5.90(137-x)=1000.60

The value of the composite function f(g(x)) is calculated as f(g(x)) = 65.

Composite functions is one in which one function is placed within another.

For, the given values in the question;

f(x) = 9x+2 and g(x) = x-2

We have to find the value of f(g(x)) for x = 9.

First estimate the value of g(x) by substituting  x = 9 in it.

g(x) = x-2

g(9) = 9-2 = 7

Now,

f(x) = 9x+2 and

f(g(x)) = f(7) = 9x+2, (substitute x = 7)

f(g(x)) = 9×7 + 2

f(g(x)) = 65.

Thus, the value of the composite function f(g(x))  = 65.

The times associated with each speed are:

It is always true that the speed is inversely proportional to time.

In this case we find the situation of bicycle moving at constant speed, where the traveled distance (s), in miles, is equal to the following expression:

s = v · t           (1)

Where:

Now we proceed to calculate time needed for each speed:

t = s / v

Case 1

t = 100 mi / 5 mi / h

t = 20 h

Case 2

t = 100 mi / 10 mi / h

t = 10 h

Case 3

t = 100 mi / 15 mi / h

t = 6.667 h

Case 4

t = 100 mi / 20 mi / h

t = 5 h

Case 5

t = 100 mi / 25 mi / h

t = 4 h

Considering the definition of combination,  if a family has 5 children, in 10 ways the parents can have 2 boys and 3 girls as children.

Combinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.

To calculate the number of combinations, the following expression is applied:

[tex]mCn=\frac{m!}{n!(m-n)!}[/tex]

where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.

If a family has 5 children, you can know that:

So, you can observe that 5C3 is equal to 5C2. Then:

5C3 = 5C2 = [tex]\frac{5!}{3!2!}[/tex]= 10

Answer:

angle A=125 angle B= 114 angle C= 121

Step-by-step explanation:

first you have to find x so that you can find each angle

the interior angles of a triangle is equal to 360

add the angles together x+x+7+x+11=360

combine like terms 3x+18=360

subtract 18 on both sides 3x=342

divide by 3 on both sides x=114

to find angles:

plug in X to each side

(114)+7 = angle C

(114)+11= angle A

114= angle B

The number of months so that the investment gets double will be 86 months.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on. The amount is given as,

A = P + (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

The principal amount is $450 and if the amount gets doubled, then the value of the amount will be $900. The simple interest rate is 14%. Then the time is given as,

A = P + (PRT)/100

900 = 450 + [450 x 14 x T] / 100

450 = 450 x 14 x T / 100

T = 100 / 14

T = 7.14 years

T = 7.14 x 12

T = 85.7 ≈ 86 months

The number of months so that the investment gets double will be 86 months.

Answer:

Step-by-step explanation:

4 is the maximum number of days.

Using Inequality, the maximum number of days that Lily can rent the car while staying within her budget is 4 days.

The rental car company charges $71.02 per day to rent a car and $0.12 for every mile driven.

Lily wants to rent a car and she plans to drive 475 miles. She has a budget of $390.

Therefore, the maximum number of days that Lily can rent the car while staying within her budget can be calculated as follows:

Using inequality,

total cost = 71.02(x) + 0.12(y)

where

x = number of days

y = number of miles

Therefore,

71.02x + 0.12(475) ≤ 390

71.02x ≤ 390 - 57

71.02x ≤ 333

x ≤ 333 / 71.02

x ≤ 4.68882005069

Therefore,

she can drive maximum of 4 days.

The minimum divisor such that the dividend is greater than 1000 and a quotient of 52 with a remainder of 18 is 18.86.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variable called division.

Let's consider a division problem.

5/2 → 2 + 1

Here 5 is called the dividend,2 is the divisor,2 is the quotient, and 1 is the remainder.

Now,

2  × 2 + 1 = 5

Therefore,divisor × quotient + remainder = dividend

So,

Let's suppose the divisor in the given case is x

Now,

52x + 18 ≥ 1000

Since he will rent a car that costs $50 per day and $ 0.50per mile, the expression will be:

50 + 0.50m = 500

where m  = number of miles

Collect like terms

0.5m = 500 - 50

0.5m = 450
