There is no graph but...
A solution to a system is a ordered pair that is located in the line of the graph.
Answer:
47.3 grams
Step-by-step explanation:
Given: A solution contains 4.3 grams of salt per liter.
To find: Amount of salt in 11 liters of the solution
Solution:
Amount of salt in 1 liter of the solution = 4.3 grams
So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams
Hence, 11 liters of the solution contains 47.3 grams of salt.
Answer:
x = 17
Step-by-step explanation:
Since the triangle is isoceles that means angle UTV is also 43 degrees. The sum of all angles in a triangle is 180 degrees. So construct this equation. 43 + 43 + 43 + 8x - 42 = 180. Now solve for x.
I’m pretty sure it’s 20(4+5)
Answer:
Step-by-step explanation:
Depends upon what you're looking for! If you want the area under the standard normal curve to the left of z = -3.49, here's one way to do it on a TI 83 calculator:
normcdf(-100, -3.49). Because the z-value -3.49 is more than 3 standard deviations below the mean, the area to the left of z = -3.49 resembles 0.002. Try this on your calculator: normcdf(-100, -3.49)
