Solve the inequality
of these equation
pretty please
Answer:
y<6
Step-by-step explanation:
1 /3 y + 1/4 > 3 /8y
1 /3 y + 1/4 − 3/ 8 y > 3/ 8 y − 3/ 8 y
− 1 /24 y + 1 4 > 0
−1 /24 y + 1 /4 − 1/ 4 > 0 − 1 /4
−1 /24 y > −1/ 4
Multiply both sides by 24/(-1).

Answer:
274.75 yd³Step-by-step explanation:
First we can tilt this shape so it sits flat. This is just to make it easier.
Since we know the diameter, the formula will be different.
[tex]V=3.14(\frac{d}{2})^2h[/tex]
Now lets rewrite it replacing variables.
[tex]V=3.14(\frac{10}{2})^23.5[/tex]
Solve. While solving this, order of operations is critical.
10/2 = 5
5² = 5 × 5 = 25
3.14 × 25 = 78.5
78.5 × 3.5 = 274.75
Now we need to add the measurement unit which is yards or yd.
We also need to add ³ since it is volume
274.75 yd³ is our final answer

An online retailer has two warehouses, M and N, where customers' orders are packaged and shipped. The number of orders per day for warehouse M has a mean of 1,417.31 and a standard deviation of 67.54. The mean number of orders per day is 1,505.39 for warehouse N with a standard deviation of 67.70. Explain how the number of orders per day for warehouse M compare to the number of order per day for warehouse
A The number of orders per day for warehouse N is less on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is greater than the standard deviation in warehouse M.
BThe number of orders per day for warehouse N is greater on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.
C The number of orders per day for warehouse M is about the same on average to the number of orders per day for warehouse N. The standard deviation for the number of orders per day in warehouse M is greater than the standard deviation for warehouse N.
D The number of orders per day for warehouse M is greater on average than the number of orders per day for warehouse N. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.
Answer:
B. The number of orders per day for warehouse N is greater on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.
Step-by-step explanation:
Wearhouse M has an average of 1,417.31 orders shipped per day, and Warehouse N has an average of 1,505.39 packages shipped per day. meaning that Wearhouse N has a greater mean (or average) compared to Wearhouse M.
Wearhouse M has a standard deviation (The safety net of how much the average can change) of 67.54 and Wearhouse N has a standard deviation of 67.70 which means that these are practically the same number.

If the sum of the measures of the interior angles of a polygon is 1980 degrees, how many sides does it have? I need an explanation to this!
Answer:
It has 13 sides.
Step-by-step explanation:
The equation for total interior angle is x = 180(n - 2)
fill it out and solve
1980 = 180(n - 2)
1980 = 180n - 360
2340 = 180n
n = 13
