The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
Answer:
1) 85.7%
2) 93%
3) 96.5%
4) 94%
Step-by-step explanation:
Sorry if any of these are wrong. I used the formula a/w= p/100. a is the part, w is the whole and p is the percent.

Answer: i am the first one to answer please mark brainliest
65x3 + 450x4=
Step-by-step explanation:
195+1800=1995
Answer:
1,955 miles
Step-by-step explanation:
For this problem all we have to do is, assuming they were constantly going that speed and never stopped, multiply the items and the mph.
SO, to the airport is 65mph*3 hours, which would give 195 miles.
Then, To their destination, 450mph * 4hours = 1,800 miles
Now all that is left to do is add
195 + 1,800 = 1,995
1,995 miles

Can someone help me with my math if you help me i will give you a brainliest
Answer:
Step-by-step explanation:
So its difficult to show
Y= X-6 so what ever x is, y is six less than that so
X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line
Hope this helps

The radius of a circle is 2.6 in. Find the circumference {to the nearest tenth}to the nearest tenth.
Answer:
The answer would be 16 I think. 16
Answer:
16.3 in
Step-by-step explanation:
The equation for circumference of a circle is 2[tex]\pi \\[/tex]r
r is the radius
Plug the given value for radius (in this problem that is 2.6) into the equation and you get the circumference of the circle.
2[tex]\pi \\[/tex](2.6)=16.3

A bake sale committee wants to raise $198 for a donation to a local charity. They set aside $12 of their profit at the end of each day. How many days will it take them to raise enough money for the whole donation?
Answer:
It will take about 17 days in order to obtain the money needed.
Step-by-step explanation:
I took 198 and then -12 each time and counted along until I found my answer.
Answer:
17
Step-by-step explanation:
First you do 198 divided by 12 and then you get the remainder 6. Since the put 12 dollars every day you have to add another day so you get the total amount of days.
