A number is 11 less than 3 times another number. The sum of the numbers
is 25. What are the two numbers?
Can you please send the work too
Answers
Step-by-step explanation:
this is simple use it and enjoy
Step-by-step explanation:
Let x be the first number
Let y be the 2nd number
given,
[tex]x = 3y - 11 \\ x - 3y = - 11[/tex]
as equation 1
and
[tex]x + y = 25[/tex]
as equation 2.
Now we will use elimination method to solve for simultaneous equations.
We will use equation 1 - equation 2 to eliminate x to solve for y.
[tex]x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9[/tex]
Substitute y into equation 2.
[tex]x + 9 = 25 \\ x = 25 - 9 \\ = 16[/tex]
The numbers are 9 and 16.
What is the value of x in a 45-45-90 triangle and the hypotenuse is 4?
Answers
9514 1404 393
Answer:
x = 2√2 ≈ 2.83
Step-by-step explanation:
The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...
x = 4/√2 = 4(√2)/2
x = 2√2 ≈ 2.83

Step-by-step explanation:
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.
Answers
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.

Can someone please help me with this questions The points H,I,J and K all lie on the same line segment, in that order, such that the ratio of HI:IJ:JK is equal to 2:2:3. If HK=49, find IJ.
Answers
Answer:
IJ = 14Step-by-step explanation:
If the point HIJK all lies on the same line, then HI + IJ + JK = HK
2 + 2 + 3 = HK
HK = 7
Since the total length is HK
IJ = ratio of IJ/Total ratio * HK
IJ = 2/7 * 49
IJ = 2 * 7
IJ = 14
Hence the length of IJ is 14

Step-by-step explanation:
supplementary angles are two angles that add up to 180 degrees, so essentially two angles that, combined, are equal to a straight line.
vertical angles are angles that are opposite each other when two lines cross.
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!
Answers
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
