At the beginning of the year, Adrian's savings account balance was $28. Each week, he deposits another $15 into that account, and he doesn't spend any of his savings.
Is his savings account balance proportional to the number of weeks since the start of the year?

Answers

Answer 1

No, because 28 and 15 have no common numbers in multiplying. and if you graph those in a line graph it is not a straight line and in order to be proportional the graph line has to pass the origin and be a straight line.

Answer 2

Answer:

The given condition is not proportional.

Step-by-step explanation:

At the beginning of the year, Adrian's savings account balance was $28.

Let Adrian invests for 'x' weeks.

So, total amount will becomes :

[tex]28+15x[/tex]

Since 4 weeks = 1 month, it will represent a linear equation only.

Linear functions have a constant rate of change and describe a straight line on a graph. So, this is not proportional.

The given equation is in the form y = mx + b, so its linear. For the equation to be proportional, it should be in the form of y = kx.

How do I solve this?

Answers

The solution is -8+8 is 0 then The k/10 =-8 bring 10 to -8 it will get multiplied 10*-8=-80 so k=-80

1. Isolate the absolute value.
2. Set the inside of the absolute value equal to positive and negative of the right side and solve both equations. Very often you get two solutions.

-8 + 8|k/10| = -8

Add 8 to both sides.

8|k/10| = 0

Divide both sides by 8.

|k/10| = 0

Now set k/10 equal to 0 and -0.
Since -0 is the same as 0, in this case you will only get one equation from the absolute value part.

k/10 = 0

Multiply both sides by 10.

k = 0

Step-by-step explanation:

A popular chain of superstore makes 30.479×10730.479×107 dollars in profit each year. One of its store makes 210.2×104210.2×104 in profit each year.

How many times greater is the profit made by the chain than by one of its store?

Enter your answer, using scientific notation, in the boxes.

Answers

Final answer:

To find how many times greater the chain's profit is than one store's, divide the chain's profit by the store's profit. After dividing the coefficients (30.479/210.2) and subtracting the exponents (7-4), we find that the chain's profit is 145 times greater than that of one store, which is 1.45 × 10² in scientific notation.

Explanation:

To determine how many times greater the profit made by the chain is than by one of its store, we need to divide the total profit of the chain by the profit of one store. Both profits are given in scientific notation as follows:

Chain's annual profit: 30.479 × 107 dollars

One store's annual profit: 210.2 × 104 dollars

To perform the division, we divide the coefficients and subtract the exponents:

(30.479 × 107) / (210.2 × 104) = (30.479 / 210.2) × 10(7 - 4)

Calculating the division of coefficients and exponents separately:

Coefficients: 30.479 / 210.2 ≈ 0.145

Exponents: 103, since 7 - 4 = 3

The result is:

0.145 × 103, which is the same as 1.45 × 102 in scientific notation after adjusting the decimal point one place to the right. Therefore, the chain's profit is 145 times greater than the profit of one store.

Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?

Answers

Final answer:

To find Seth and Eric's current ages, we can set up two equations using the given information and solve them simultaneously.

Explanation:

To solve this problem, let's start by assigning variables to the ages of Seth and Eric. Let Seth's age be represented by 'S' and Eric's age be represented by 'E'. We are given that currently Seth's age is 4/5 the age of Eric:

S = (4/5)E

We are also given that twenty-one years ago Eric was twice as old as Seth:

E - 21 = 2(S - 21)

Now we can solve these equations simultaneously to find their current ages. Let's substitute the value of S from the first equation into the second equation:

E - 21 = 2((4/5)E - 21)

Simplifying the equation, we get:

E - 21 = (8/5)E - 42

Moving all the terms with 'E' to one side, we get:

(8/5)E - E = 42 - 21

Simplifying further, we get:

(3/5)E = 21

To solve for E, we can multiply both sides of the equation by 5/3:

E = (5/3) * 21 = 35

Now that we know Eric's age, we can substitute this value back into the first equation to find Seth's age:

S = (4/5) * 35 = 28

Therefore, Eric is currently 35 years old and Seth is currently 28 years old.

Which statement and explanation about the product of a 3-digit number and a 2-digit number is correct?

A. The product always has 4 digits. The least 3-digit number is 100, and the least 2-digit number is 10. The product of 100 and 10 has 4 digits, so any product of a 3-digit and a 2-digit number must have 4 digits.
B. The greatest number of digits in the product is 6. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 3 digits and 2 digits equals 6 digits, so no product of a 3-digit and a 2-digit number can have more digits.
C. The product always has 5 digits. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so any product of a 3-digit and a 2-digit number must have 5 digits.
D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.

Answers

Its D- 999*99 is a 5 digit #, but 100*10 is a 4 digit- 1000- so it can be less.

The correct statement is :

D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.

The smallest 2 digits is 10, and the smallest 3 digits is 100

Their product is:

[tex]10 \times 100 = 1000[/tex] i.e. 4 digits

The greatest 2 digits is 99, and the greatest 3 digits is 999

Their product is:

[tex]99 \times 999 = 98901[/tex] i.e. 5 digits

This means that;

No product of the digits can have more than 5 digits

And, no product can have less than 4 digits

Hence, (d) is correct

How to plot a graph?

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

The point of intersection of the line and x-axis = (2,0)

The point of intersection of the line and y-axis = (0,3)

The slope of the graph or line

Slope = differcne in ys coordinate/difference in xs coordinate

Slope(m) = (3-0)/(0-2) = -3/2

Now equation of a line is given by

y = mx + c

Now keep point (2,0) and slope-3/2

0 = (-3/2)2 + c

c = 3

So, the equation would be

y = (-3/2)x + 3

Hence, The equation of the given graph will be y=-3/2x+3

Ten years from now Sam will be twice as old as she was three years ago.How old is she now?

Answers

Answer:

is ther any information about how old he will be in ten years from now

Step-by-step explanation:

Sam's current age is 16 years old based on the provided condition.

Ten years from now, Sam will be twice as old as she was three years ago. Let's represent Sam's current age as x. According to the given condition:
Age after ten years = x + 10
Age three years ago = x - 3
Given that the age after ten years will be twice the age three years ago:
x + 10 = 2(x - 3)
Solving for x:
x + 10 = 2x - 6
x = 16

Therefore, Sam is currently 16 years old.

Answers

I'd say the graph isn't functional

A line can be determined with two points.

The y-intercept is where a graph intersects the y axis.

Let 2 points lie on the y axis. Those are the y-intercepts.

2 lines can only have 0 intersections, 1 intersection, or infinitely many intersections.

Thus, if a line intersects another line more than 2 times, both lines must be the same line.

Using that information to create a line, you would have the line x=0.

x=0 is a vertical line that intersects the y-axis infinitely many times since they are the same line.

However, x=0 is not a function.
