Answer:
8. 10%
9. 50%

Step-by-step explanation:
I am pretty sure I got it right otherwise I think I have a big problem
Answer:
10 kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
9 the percent error is 33.3%
8 20% error

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

Answer: m=2.8
Step-by-step explanation:
You can reverse the equation and instead solve...
4-1.2 which equals 2.8.
m=2.4Answer:
m = 2.8
Step-by-step explanation:
m+1.2=4
move all terms containing m to the left and all other terms to the right.
+1m=+4-1.2
simplify left and right side of the equation.
+1m=+2.8
divide both sides of the equation by 1 to get m.
m=2.8

He makes 800lb of trail mix that is 40% raisins. How many pounds of each trail mix does the manager use?
Answer:
320 pounds of 55% raisins trail mix
480 pounds of 30% raisins trail mix
Step-by-step explanation:
Sorry, I can’t write how I got the answer. We just did it in class and decided to help... (Btw, sorry if I’m too late)
The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.
Given that,
A store manager combines a trail mix that is 30% raisins with a trail mix that is 55% raisins.
He makes 800lb of trail mix that is 40% raisins.
We have to determine,
How many pounds of each trail mix does the manager use?
According to the question,
Let, x = pounds of trail mix 30% raisins
y = pounds of trail mix 55% raisins
The distributor wants to make 800 pounds of trail mix, thus:
x + y = 800
The mix must be 40% raisings as a combination of x and y, thus:
30x + 55y = 40 × 800
30x + 55y = 32,000
Divided by 5 the equation
6x + 11y = 6400
Solving both the equation
[tex]x + y = 800\\\\x = 800 -y\\[/tex]
Substitute the value of x in equation 2,
[tex]6x + 11y = 6400\\\\6 (800-y) + 11y = 6400\\\\4800 - 6y +11y = 6400\\\\5y = 6400-4800\\\\5y = 1600\\\\y = \dfarc{1600}{5}\\\\y = 320[/tex]
Substitute the value of x in equation 1
[tex]x + y = 800\\\\x + - 800 -y\\\\x = 800-320\\\\x = 480[/tex]
Hence, The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.
