First, find her rate for the day. Since she runs 10 laps a day, multiply.
400 times 10= 4000
Next, I'll convert kilometers into meters;
12 times 1000=12,000
Divide to find the days:
12,000/4,000=3
It will take 3 days to run a total of 12 kilometers.
Answer:
Look at the place after the tenths, it is more than 5.
99.999
So add +1 to the tenths place.
Rounded to the nearest tenth would be:
<h2>100.0</h2>
<span>y=3x-12
2x-3y=-13
substitute </span>y=3x-12 into <span>2x-3y=-13
</span><span>2x-3y=-13
</span>2x-3(3x-12)=-13
2x - 9x + 36 = -13
-7x = -49
x = 7
y=3x-12 = y=3(7) -12 = 21 - 12 = 9
answer
solution
x = 7 and y = 9
Answer:
23.3
(or 
(let me know if you wanted this one and is you want it explained) lol)
Step-by-step explanation:
To find the length of the fence, use the Pythagorean theorem because, if you cut a rectangle diagonally, you will create two right triangles, and this formula only works with right triangles:
Insert values:
Solve for c:
Evaluate exponents
Simplify addition
Find the square root of both
The fence needs to be approximately 23.3 m.
Sorry I can’t read that hand writing if I could just write it on brainly
