St meaans s times t
s=-4
t=9
st=-4 times 9
negative times positive=negative
4 times 9=36
-4 time s9=-36
st=-36
answer is -36
Answer:
If both computers are working together, it will take 24 minutes to do the job
Step-by-step explanation:
It is given that,
There are two computers.The slower computer can send all the company's email in 60 minutes.
The faster computer can complete the same job in 40 minutes
<u>To find the LCM of 40 and 60</u>
LCM (40, 60) = 120
<u>To find efficiency of 2 computers</u>
Let x be the efficiency of faster computer and y be the efficiency of faster computer
x = 120/40 = 3
y = 120/60 = 2
then, x + y = 3 + 2 = 5
Therefore efficiency of both the computer work together = x + y =5
<u>To find the time taken to work both the computer together</u>
time = 120/5 = 24 minutes
Answer:
Step-by-step explanation:
Given
Required
Determine the change received
First, we need to calculate the total amount spent
This implies that Natalie pays a total of $41.18
Next, we calculate the change as thus:
<em>Hence, the change is $8.82</em>
These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)
remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line
the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,
2nd is wrong as well, has only 1 point, the center
3rd is right
4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?
3rd on is answer
