You are debating about whether to buy a new computer for $800.00 or a refurbished computer with the same equipment for $640.00. If a savings account earns 4.5% APR interest, how much do you really save with a refurbished computer if you put the difference into the savings account for a year?

Firstly, we need to find the difference between the two. First, we have to take a grand total of $800 and subtract it by the used/refurbished total of $640. After we subtract the two, we would get $160. Next, we want to multiply the $160 by our interest rate. In this case, the interest rate is 4.5%. To convert this to a decimal, we do 0.045. When we multiply $160 by 0.045 we get $7.20. So the final total would be $167.20.

Therefore, you would get $7.20 out of interest!

QUESTION POSTED AT 17/10/2019 - 09:14 AM

A school principal ordered 1000 pencils he gave an equal number to each of seven teachers until he had given out as many as possible how many pencils were left

If you have 1000 pencils and you divide by 7 teachers, you would have 142 pencils divided evenly. Then you would take the 142 pencils and multiply by 7 which will give you a total of 994 pencils that went to the teachers in total. So the remaining pencils would be 1000 minus 994 and the total left over will be 6 pencils. I hope this helps.

Which calculation should be completed first to solve this story problem? Allister bought some sheet music. He bought 6 songs for $0.99 each and 1 book for $16.99. He paid $1.38 in sales tax. He gave the cashier $50. How much change should Allister get? A. total cost of all the purchases B. total cost of 6 songs C. sum of the cost of 1 song, the book, and the tax D. the change

A. total cost of all the purchases

You can't calculate the sales tax on the sheet music or the change for $50 he would have received (which requires subtracting the total cost from $50) until you know how much the sheet music cost total.

 The B) and C) options aren't  relevant to the problem. You're trying to find the amount of change he gets after paying the total cost for all the sheet music + the tax on that.

Hey there!

If the total amount of times Mark recorded the color of the traffic light is 15, then the number of red lights he recorded would be 15 minus the amount of green and yellow lights. 

15 – 6 – 2 = 7

There was a total of 7 red lights recorded by Mark.

QUESTION POSTED AT 17/10/2019 - 09:09 AM

Identify as a direct variation, inverse variation or neither. Is the total cost to fill a car gas tank a direct or inverse variation with respect to the number of gallons used?

Answer:

It  is a case of a direct variation.

Step-by-step explanation:

Direct variation--

Two variables x and y are said to be in direct variation if there exist a constant k such that:

y=kx

i.e. with the increase/decrease in one variable the other variable also increases/decreases.

Inverse variation--

Two variables x and y are said to be in inverse variation if there exist a constant k such that:

xy=k

i.e. with the increase in one variable the other decreases and vice-versa.

Here the independent variable is: Number of gallons used.

and the dependent variable is: Total cost to fill a car gas tank.

As we know that as the number of gallons used increases the total cost also increases and it increases by some constant k.

Since, the cost of per gallons is some fixed.

QUESTION POSTED AT 17/10/2019 - 09:06 AM

Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 3:35 to 3:55? (Hint: Find the number of degrees per minute first.) Part 2: How far does the tip of the minute hand travel during that time?

Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20

part2

\bf \textit{length of an arc}\\\\&#10;s=\cfrac{r\theta\pi }{180}\qquad &#10;\begin{cases}&#10;r=radius\\&#10;\theta=\textit{angle in degrees}\\&#10;----------\\&#10;r=4\\&#10;\theta=6\cdot 20&#10;\end{cases}\implies s=\cfrac{4\cdot 6\cdot 20\cdot \pi }{180}
