     %error=(calculated value - experiemental value)/calculated * 100%

 

%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error

the sum of 2 numbers is 100. one number is 5 less than twice the other. find the 2 numbers.

Answers

Answer:

35 and 65

Step-by-step explanation:

Let the two numbers be x and y.

Thus

x + y = 100

and

x = 2y - 5

Now substitute for x in the first equation and get

2y - 5 + y = 100

3y - 5 = 100

3y = 105

y = 35 and since they add to 100,

x = 65

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.


*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Answer:

give more detials

Step-by-step explanation:

To write the equation of the line in slope intercept form, you would need to solve to find the slope. The slope in this case is 2. We know that because 3-(-1)/5-3= 4/2.

And then to find the y-int we would need to substitute the known values on the equation y=mx+b . Using the point (5,3) we can calculate the intercept. We do 3=2(5)+b. We get that b=-7.

Now in the end the equation in slope intercept form will be
y=2x-7

A total of $8000 is invested in 2 funds paying 4% and 5% annual interest. The combined annual interest is $350. How much of the $8000 is invested in each fund? Please show work!!

Answers

Answer:

$5000 and $3000

Step-by-step explanation:

x = money invested in the first fund

y = money invested in the second fund

first equation: 0.04x + 0.05y = 350

4x + 5y = 35000

second equation: x + y = 8000

x = 8000 - y

Plug in x into the second equation:

4(8000 - y) + 5y = 35000

Solve:

32000 - 4y + 5y = 35000

y = 3000

x = 8000 - y

x = 8000 - 3000

x = 5000

$5000 and $3000

Hope this helps!

Answer:

$3000.

Step-by-step explanation:

$Po invested at 4%.

$(8000-Po) invested at 5%

Po*0.04*1 + (8000-Po)*0.05*1 = 350.

0.04Po + 400 - 0.05Po = 350,

Po = $5000.

8000-Po = 8000-5000 = $3000.

Hope this helps :)
