Mila invested $1,500 in an account in the year 2010, and the value has been growing exponentially at a constant rate. The value of the account reached $2, 100 in the year 2015. Determine the value of the account, to the nearest dollar in the year 2024.
Answer:
$3867.80
Step-by-step explanation:
f(x)=a(1+r)^{x}
f(x)=exponential growth function
a=initial amount
r=growth rate
{x}=number of time intervals
so let x=years
start amount is 1,500
1,500(1+r)^5=2100
(r+1)^5= 7 /5
((r+1)5) ^1 /5 =( 7 /5 ) ^1 /5
r=0.06961
which is rounded 7 percent growth rate
2024-2010=14 years
1,500(1+0.07)^{14}=

max picks two different cards without replacement from a standard $52$-card deck. what is the probability that the cards are of different suits?
The probability that cards are from different suits is [tex]\frac{39}{51}[/tex]
Probability of an event E represented by P(E) can be defined as (The number of favorable outcomes )/(Total number of outcomes).
There are 4 suits hearts, diamonds, club and spade in a standard deck of 52 cards.
Each of them has 13 cards each .
So when we pick first card from a single suit
we can pick it in 13 ways , now 12 cards are left.
We can pick the 2nd card from the same suit in 12 different ways .
So to pick 2 cards from a single suit we have 13x12 ways.
to pick 2 card from 4 suits = 4x13x12=624 ways
Total ways of choosing 2 cards from the pack of 52 cards is 52 X 51 =2652
probability that the cards are of same suits=[tex]\frac{624}{2652} =\frac{12}{51}[/tex]
probability that the cards are of different suits=[tex]1-\frac{12}{51} =\frac{39}{51}[/tex]

Answer:
6.25 cups of water
Step-by-step explanation:
So I first write out the rates: 4:2.5 and also 10:?
So let's find out how the scoops changed, as in how did you get 4 to become 10 so you can do the same thing to 2.5 and get ?.
To go from 4 to 10 you MULTIPLY/DIVIDE. DON'T ADD OR SUBTRACT. 10 divided by 4 (to see what you multiplied by) is 2.5.
So we multiplied 4 by 2.5 to get 10. So if we multiply 2.5 by 2.5 we get 6.25.
So 4:2.5 = 10:6.25
?=6.25

what is equation of straight line shown below give answer in form y=mx+c where m and c are intervenes or fractions in simplest form
The equation of the straight line is y = 2x + 6.
What is an equation of a line?An equation of a line is a mathematical expression that describes the relationship between the x and y coordinates of the points on the line. There are several different forms of the equation of a line, but the most commonly used is the slope-intercept form:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
We have,
To find the equation of the straight line passing through the points (-3, 0) and (0, 6), we can use the slope-intercept form of a linear equation, which is:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We can first find the slope of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
[tex]where ~(x_1, y_1) = (-3, 0) ~and ~(x_2, y_2) = (0, 6):[/tex]
So,
m = (6 - 0) / (0 - (-3)) = 6/3 = 2
Now we can substitute the slope and one of the points into the slope-intercept form to find the y-intercept:
y = mx + c
0 = 2(-3) + c
0 = -6 + c
c = 6
Therefore,
The equation of the straight line is y = 2x + 6.

Solve 5x+2=20
Answer:
x = 18/5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
5x + 2 = 20
Step 2: Solve for x
Subtract 2 on both sides: 5x = 18Divide 5 on both sides: x = 18/5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(18/5) + 2 = 20Multiply: 18 + 2 = 20Add: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = 18/5 is a solution to the equation.

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Given that
Total amount of solution = 90
total amount of salt = 15 % of 90
= [tex]90 \times \frac{15}{100}[/tex]
= 13.5
Now removed X from the solution
Then, remaining solution is 90 - X
Percentage of salt in the remaining solution [tex]= \frac{salt}{remaining solution}[/tex]
Given that , % of salt in the remaining solution is equal to 25% then, Percentage of salt in the remaining solution
⇒ [tex]\frac{salt}{remaining solution}[/tex] = 25%
⇒ [tex]\frac{13.5}{90 - X} = \frac{25}{100}[/tex]
⇒1350 = 2250 - 25 x
⇒ 25 x = 2250 - 1350
⇒ 25 x = 900
⇒ x = [tex]\frac{900}{25}[/tex]
⇒ x =36

Answer:
The equations are;
4(2x + 5) = 3(2x + 8)
x = 2
Perimeter of each shape is 36
Step-by-step explanation:
Mathematically;
The perimeter of a square is 4L
while the perimeter of an equilateral triangle is 3L
where L represents the lengths of the sides
Mathematically, from what we have in the question, since the perimeter are equal;
4(2x + 5) = 3(2x + 8)
8x + 20 = 6x + 24
8x-6x = 24-20
2x = 4
x = 4/2
x = 2
The side of the square will measure;
2(2) + 5 = 9
Its perimeter is 4(9) = 36
The side of the triangle will measure
2(2) + 8 = 12
Its perimeter will be 3(12) = 36
