Owen receives $10 and puts it into his savings account. He adds $0.50 to the account each day for a number of days, d, after that. He writes the expression 10 + 0.5(d – 1) to find the amount of money in his account after d days. Which statement about his expression is true?

Answers

Answer 1

Answer:

Answer:

It is the sum of the initial amount and the additional amount after days.

Step-by-step explanation: its on TTM

Answer 2

Answer:

well it depends on the number of days but here's how you do it. you use d as a substitute for the number of days so....

10+0.5(d-1)= 10+0.5(1-1)=10

10+0.5(d-1)=10+0.5(2-1)=10.5

10+0.5(d-1)=10+0.5(3-1)=11

and you just keep on plugging the next number up in replace for d for the number of days that there are.

I hope this helped.....

23.15 – [ 115 + ( 12 - 25)]

Answers

Answer:

-78.85

Step-by-step explanation:

Using Order of Operations (PEDMAS):

23.15 – [ 115 + ( 12 - 25)]

= 23.15 – [ 115 + (-13)]

= 23.15 – [ 115 - 13]

= 23.15 - 102

= -78.85

The combined volume of two identical cubes is 250 cubic centimeters. What is the measure of one cubes edge

Answers

5 cm

Further explanation

Given:

The combined volume of two identical cubes is 250 cubic centimeters.

Question:

What is the measure of the edge of one cube?

The Process:

Firstly, let's make a diagram that suitable for the information above. Notice that we have two identical cubes. Therefore, we divide the volume of two cubes into two equal parts to prepare the volume of one cube.

$\boxed{125 \ cm^3}\boxed{125 \ cm^3} = 250 \ cm^3 \ or \ \boxed{ \ 250 \ cm^3 / 2 = 125 \ cm^3 \ }$

Hence, the volume of a cube is 125 cm³.

Secondly, we will find out the measure of the edge of one cube.

In a cube, all the sides are the same.

Recall the volume of a cube is $\boxed{ \ V = s * s * s \ or \ V = s^3 \ }$ , where s is the length of one side of the cube, or, the measure of one cubes edge.

Let us calculate the side length of each cube.

$\boxed{ \ s * s * s \ = 125 \ }$

$Since \ \boxed{125 / 5 = 25} \ and \ \boxed{25 / 5 = 5}, hence \ \boxed{5 * 5 * 5 = 125}$

Thus, the measure of one cubes edge is 5 cm.

A company offered one half of its employees a bonus if the production of cookies increased by 15%. The other half of the employees was not offered a bonus. As the end of the month, production in the group that did not get the bonus offer increased by a mean of 20 and production in the bonus group increased by a mean of 10. What is the correct order of steps to determine if the results are significant? A. Calculate the probability of a difference of 10. B. Calculate the difference of the means. C. Randomly separate the employees' individual results into two groups. D. Calculate the mean of each group. E. Run the experiment many times.

Answers

Answer:

Company revealed that, One half of employees will get bonus, if the production of cookies increased by 15 %.

And , other half of employees will not get the bonus.

And,

The group who didn't get the bonus, their production increased by mean of 20.

And, the production in the bonus group increased by mean of 10 only.

To check whether results are significant or not,we will follow the following steps

1. C. Randomly separate the employees' individual results into two groups.

2. D.Calculate the mean of each group.

3. B. Calculate the difference of the means

4. E. Run the experiment many times.

5. A .Calculate the probability of a difference of 10

The answer for this question is C, D, B, E, A. I hope that helps!

How are the two functions f(x) = 0.7(6)^x and g(x) = 0.7^-x related to each other?

Answers

to find the relationship between them, lets do some algebra:

f(x) = (7/10)^x

g(x) = (7/10)^-x

if we do:

f(x) * g(x) = 1

due to exponents multiplying addition law, therefore, the relationship, gives:

f(x) = 1 / g(x)

Answer:

We will see that g(x) is a reflection over the y-axis of f(x).

How does a reflection work?

For a given function f(x), we can define:

A reflection over the x-axis as: g(x) = -f(x)

A reflection over the y-axis as: g(x) = f(-x).

In this case we have:

f(x) = 0.7*(6)^x

g(x) = 0.7*(6)^-x = f(-x)

So is ratter easy to notice that g(x) is a reflection over the y-axis of f(x), so the correct option is:

"g(x) is the reflection of f(x) over the y-axis."
