Answer:
Marci is the faster runner.
Step-by-step explanation:
Sandi can run 348 cm in a second. Let's find out how many cm she can run in a minute: in a minute there are 60 seconds. So lets multiply 348cm times 60, this gives you 20,880. That is how much she travels in a minute, now let's find out how much she runs in an hour: if she runs 20,880 cm in an minute and there are 60 minutes in an hour, then all you have to do is multiply 20,880 times 60, this gives you 1,252,800. That is how many cm she runs in an hour. Now let's change from cm to miles. There are 160,934 cm in a mile. If we divide 1,252,800 by 160,934 this will give you
Answer:
Step-by-step explanation:
Count the number of elements in A
n(A) = 4
Step-by-step explanation:
Solving
3x + -6y = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
3x + -6y + 6y = 42 + 6y
Combine like terms: -6y + 6y = 0
3x + 0 = 42 + 6y
3x = 42 + 6y
Divide each side by '3'.
x = 14 + 2y
Simplifying
x = 14 + 2y
Answer:The fraction with the lowest value is - 7/8
Step-by-step explanation:
The fractions are
-1/8, -5/8, -7/8, or -3/8
We will convert each fraction to decimal.
-1/8 = - 0.125
- 5/8 = - 0.625
- 7/8 = - 0.875
- 3/8 = - 0.375
Arranging the decimals in an increasing order, it becomes
- 0.875, - 0.625, - 0.375, - 0.125
So the lowest fraction is
- 0.875 = - 7/8
Both triangles have 2 side lengths labeled and a common angle ( shown by the curved lines).
You could use the SAS Similarity theorem.
