Ricardo started a savings account for his daughter Ruth by depositing
$500 into the account for her
1st birthday. For each successive birthday, Ricardo deposits
$200 more than the amount deposited for the previous birthday. This is the only money deposited into the account. What is the total amount of money Ricardo will have deposited into the account for Ruth up to and including her 6th birthday?
Answer big number
Step-by-step explanation: you start with 500 then 700 for 2nd then 900 for 3rd 1100 for 4th 1300 for 5th 1500 for 6th
Answer: 6,000
Step-by-step explanation:
If it starts with 500 on the first birthday, and each year he deposits the same amount as the previous plus 200 then we get 700 for the 2nd year.
3rd year: deposits 900
4th year: deposits 1100
5th year: deposits 1300
6th year: deposits 1500
500+700+900+1100+1300+1500=6000
Answer: $6000
hi. This is an equation on some math homework and im not sure how to do it. Could you help?Write an equation of the line that is parallel to y=16 and passes through point (−7,43)
From the given equation y=16, it implies that the line has no slope.
Hence, the slope is zero (0).
From the given point:
[tex]\begin{gathered} (-7,43) \\ x_1=-7,y_1=43 \end{gathered}[/tex]The equation of the line is given by the equation:
[tex]m=\frac{y-y_1}{x-x_1}[/tex][tex]\begin{gathered} 0=\frac{y-43}{x-(-7)} \\ 0=\frac{y-43}{x+7} \\ \text{cross}-\text{multiply} \\ y-43=0 \\ y=43 \end{gathered}[/tex]Hence, the equation of the line is y=43
suppose you get a cash prize of $100 if you win a game. the probability of winning the game is 0.7. what is the probability of winning $600 or less if you play the game 10 times, assuming that each game is independent?
The probability of winning $600 or less if you play the game 10 times, assuming that each game is independent IS 0.5630.
Define binomial distribution.A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It totals the number of trials when each trial has an equal chance of producing a particular result. The probability of success raised to the power of the number of successes and the probability of failure raised to the power of the difference between the number of successes and the number of trials are multiplied to create the binomial distribution.
Given,
Cash prize = $100
Probability of winning the game = 0.7
Using binomial distribution,
P(4 ≤X≤ 6) = P( X = 4) + P( X = 5) + P( X = 6)
P( 4 ≤ X ≤ 6)
= 1/4(0.6)⁴(0.4)⁴ + 10/5 (0.6)⁵(0.4)⁵ + 10/6 (0.6)⁶(0.4)⁶
= 0.1115 + 0.2007 + 0.2508
= 0.5630
The probability of winning $600 or less if you play the game 10 times, assuming that each game is independent IS 0.5630.

A line passes through the point (−8, – 7) and has a slope of
-5/4
Write an equation in point-slope form for this line.
The equation in the point-slope form of the line is -7 = -5/4x -8.
What do we mean by point-slope form?One of the three forms we can use to express a straight line is the point-slope form, also referred to as the point-gradient form.
This form is helpful since it allows us to find the equation of the line by only knowing the slope and one point along the line.
The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
So, the point-slope form is:
The equation of the point-slope form: y = MX + b
Where y is the y coordinate and b is the x coordinate and m is the slope.
Now, get the point-slope form as follows:
y = MX + b
-7 = -5/4x -8
Therefore, the equation in the point-slope form of the line is -7 = -5/4x -8.

That is;
150 = 15(-2) + b
150 = -30 + b
Add 30 to both-side of he equation
150 + 30 = b
180 = b
Form the equation by substituting m=-2 and b=180 into y=mx + b
y = -2x + 180
Hence, the line function is y = -2x + 180

4. Determine the root of the following equation. x-6/4-4= 3x/2+2x+1/5
The root of the given equation is x = -114/33.
We are given an equation. The equation has one variable. It is linear in nature. The equation is given below.
(x-6)/4 - 4 = (3x/2) + (2x+1)/5
We need to find the root of the equation. First of all, we will move all the terms containing the variable "x" to one side of the equation.
(x-6)/4 - (3x)/2 - (2x+1)/5 = 4
Now we will multiply the terms with the LCM of all the denominators.
20*[(x-6)/4 - (3x)/2 - (2x+1)/5] = 20*4
5(x-6) - 10(3x) - 4(2x+1) = 80
5x - 30 - 30x - 8x - 4 = 80
-33x - 34 = 80
-33x = 114
x = -114/33
Hence, the root of the given equation is x = -114/33.

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Let:
x = original sides.
x + 4 = new width
x - 2 = new feet
So:
(x + 4)(x - 2) = 91
x² - 2x + 4x - 8 - 91 = 0
x² + 2x - 99 = 0
Factoring:
(x + 11)(x - 9) = 0
x = -11 (the lenght can't be negative so this answer is not valid)

What is the height, x, of the equilateral triangle shown?
an equilateral triangle with the angles labeled as 60 degrees and a side length of 10 inches, the height labeled as x
Answer:
x = 5√3
Step-by-step explanation:
We will use the Pythagorean theorem with a and b as the lengths of the legs, and c as the length of the hypotenuse.
a² + b² = c²
We need two of the three lengths of a, b, and c, so we can find the third length.
The height divides the equilateral triangle into two right triangles.
Look at one of the right triangles.
One leg is half the side of the triangle.
a = 10/2 = 5
One leg is the height.
b = x
The hypotenuse is the side of the equilateral triangle.
c = 10
a² + b² = c²
5² + x² = 10²
