Answer:

Laura 32

Kelly 17 )

Tia 34  

Step-by-step explanation:

L+ (L-15)  + 2(L-15) = 83

4L - 45 = 83

4 L = 128

L =  32    

Laura 32

Kelly 17 (32-15)

Tia 34  (2*17)

32+17+34 = 83

Answer: Laura sold 32 boxes , Kelly sold 17 boxes and Tia sold 34 boxes.

Step-by-step explanation:

Let the number of boxes bought by Laura be x.

Then, the number of boxes bought by Kelly be x-15

and the number of boxes bought by Tia = 2(x-15)

According to the question , we have

x+x-15+2(x-15)=83\\\\\Rightarrow\ 2x-15+2x-30=83\\\\\Rightarrow\ 4x-45=83\\\\\Rightarrow\ 4x=83+45\\\\\Rightarrow\ 4x=128\\\\\Rightarrow\ x=32

Then, x-15=32-15=17\ ;\ 2(x-15)=2(17)=34\\

Hence, Laura sold 32 boxes , Kelly sold 17 boxes and Tia sold 34 boxes.

Two window washers start at the heights shown. (A: 21 ft high rising 8 in per second. The other is 50 feet high descending 11inc
babunello [35]

For this case, the first thing we are going to do is write the generic equation of motion for the vertical axis.

We have then:

h = \frac {1} {2} gt ^ 2 + vo * t + h0

Where,

  • <em>g: acceleration of gravity </em>
  • <em>vo: initial speed </em>
  • <em>h0: initial height </em>

For the first body:

h1 = \frac {1} {2} gt ^ 2 + \frac {8} {12} * t + 21

For the second body:

h2 = \frac {1} {2} gt ^ 2 - \frac {11} {12} * t + 50

By the time both bodies have the same height we have:

h1 = h2\\

\frac {1} {2} gt ^ 2 + \frac {8} {12} * t + 21 = \frac {1} {2} gt ^ 2 - \frac {11} {12} * t + 50

Rewriting we have:

\frac {8} {12} * t + 21 = - \frac {11} {12} * t + 50

\frac {8} {12} * t + \frac {11} {12} * t = 50 - 21

\frac {19} {12} * t = 29

Clearing time:

t = 29 (\frac {12} {19})\\t = 18.31s

Answer:

 it takes 18.31s for the two window washers to reach the same height

Klio2033 [76]

Answer:

10000

Step-by-step explanation:

to know if this answer is correct you have to know the rounding rules:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

The perimeter of a triangle equals 8 inches. Two of its sides are equal and each of them is 1.3 inches bigger than the third sid
mafiozo [28]
Let's call the lengths of our two types of sides <em />x and y.

The two sides will that our 1.3 inches bigger than the third side will be have length x, and the length of the other side will be known as y. Thus, x = y + 1.3.

Considering this, we can add our sides together and set this value equal to 8, given the information in the problem:
(y + 1.3) + (y + 1.3) + y = 3y + 2.6 = 8

Now, let's solve for y.
3y + 2.6 = 8
3y = 5.4
y = 1.8

Now, we are not done yet. We must determine the true lengths of all of our sides. Using the equation we found earlier, the length of the two bigger sides is y + 1.3 = 1.8 + 1.3 = \boxed{3.1} inches and the length of our smaller side is simply \boxed{1.8} inches.

To verify, we can add these sides together and check that they equal 8:
3.1 + 3.1 + 1.8 = 8 ✔
