Answer: I don’t know if you want the area or just y but anyways, y= 9

Step-by-step explanation:


The question requires a scale factor (since both triangles have similar sides (an equal ratio is a good way to think about it) the 10cm side of the large triangle is proportionate to the same side of the smaller triangle.

In other words to get that scale factor (how much one shape is bigger than the other) we need to divide the 10 by 4 (you need to use the same side you can’t do 10/6 because they are completely different sides) 10/4 = 2.5

Now we know the larger triangle is 2.5 times bigger than the smaller triangle. This means the smaller triangle is 2.5 times smaller than the big triangle. So to find the base of the larger triangle we use a similar method we used to find the scale factor (but not divide multiply because when you want to find the bigger you multiply when you want to find scale factor/ smaller you divide) so 6* 2.5= 15 and since y is not the entire base only a part of it, we can do 15(which is the entire length of the big triangle base) - 6 = 9

Therefore y=9

Complete the function remove_all(L, x) so that, given a list L and a target value x, it returns a copy of the list that excludes
tia_tia [17]

Answer:

Code is given below along with explanation and output.

Step-by-step explanation:

we can use the method of list comprehension to achieve the given task.

In a list comprehension, we create a sub-list of elements which satisfy specific conditions. the condition i !=x makes sure that x would be excluded in the modified list.

def remove_all(L, x):

   return [i for i in L if i != x]

L = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4 ]

print('Before =',L)

L = remove_all(L, 4)

print('After =',L)

Output:

Before = [1, 2, 3, 4, 5, 6, 4, 3, 2, 4]

After = [1, 2, 3, 5, 6, 3, 2]

As you can see we have successfully removed the multiple occurrence of x=4 while preserving the order of the list.

A client has orders to receive 2 liters of IV fluid over a 24-hour period with ½ this amount to be infused in the first 10 hours
Tcecarenko [31]

Answer:100 ml/hr

Step-by-step explanation:

client has orders to receive 2 liters of IV fluid over a 24-hour period

½ this amount to be infused in the first 10 hours of treatment = ½ ×2 lires

= 1 litre =1× 000 ml= 1000ml

If 1000 ml is received in 10hrs

x ml will be received in 1 hrs

x = 1× 1000/10

= 100ml per hr

If u would tell me this answer UR SOOOO NICE
Kryger [21]

Answer:

Yes

Step-by-step explanation:

Because since it tells you that x>7 and also it tells you if 7.1 is a solution. So what you need to do is plug in 7.1 instead of x and see if it's true or not. So is 7.1 greater than 7. Well yes it is and that makes it a solution. Hope this helps. Ask me any question if you need help with anything else. :)
