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 = 14

Step-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

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

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.

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.
