Two teams working together can finish a job in 8 days. if the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains. How many days will it take each team to finish the work alone?
x is the days that the first team finishes the work alone (x>8)
y --------------------------second-----------------------------------------(y>8)
In a day:
The first team finishes 1/x (the work) The second team finishes 1/y (the work) Two teams working together finish 1/8 (the work)⇒ [tex]\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}[/tex] (1)
If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:
⇒ [tex]\frac{2}{x}+\frac{5}{y}=\frac{3}{8}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.[/tex]
It'll take the first team 16 days and the second team 24 days to finish the work alone
ok done. Thank to me :>
You buy 3.18 pounds of apples, 1.25 pounds of pears, and 2.67 pounds of oranges. What is your total bill rounded to the nearest cent?
Answer:
318125267
Step-by-step explanation:
-_-...............that is the answer
3.17 pounds of apples
1.25 pounds of pears2
2.56 pounds of oranges
add = 7.98
rounded = 7.42, (or anything close. I am really bad at rounding decimals)
Write an equation for the constant of proportionality.
Answer:
they r all multiple by 3
Step-by-step explanation:
2×3=6
4×3=12
6×3=18
8×3=24
10×3=30
Answer:
Step-by-step explanation:
as hotdogs (x) increase by 2 the cost (y) increases by 6
6/2 = 3/1 = 3
y = 3x
During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution?
A x + 112 = 9x + 112 = 9
B x − 112 =−9x − 112 =−9
C −112x = −9−112x = −9
D 112x = 9
It takes about 4 days for the temperature to decrease by 9°F.
An equation is an expression that shows the relationship between two or more variables or numbers.
Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):
-1 1/2 * x = -9
-1.5x = - 9
x = 4 days
It takes about 4 days for the temperature to decrease by 9°F.

If the population of an ant hill doubles every 10 days and there are currently 100 ants living in the ant hill, what will the ant hill population be in 20 days?
Answer:
400
Step-by-step explanation:
The current number is 100, it doubles every ten days, and you're asking what the size will be in twenty days.
Beginning:
100 ants (ten days pass)
100 x 2 = 200
Middle:
10 of the 20 days have passed
Your new number is 200 ants
End:
200 ants (ten days pass)
Since every ten days the size doubles: 200 x 2 = 400
400 ants after 20 days

Answer:
$45.13
Step-by-step explanation:
what is 12% of 51.28 change 12% to a decimal by moving two spaces to left =0.12. multiple by 51.28= 6.15 that is the amount of the tip then subtract it from 51.28-6.15= $45.13 original amount before the tip.

What is the measure of the exterior angle? Show all steps.
Answer:
108 degrees
Step-by-step explanation:
The thereom for this is the interior angles (a+10) and 44 degrees add up equaling to 2a. This works for any triangle like this. So, a+10+44=2a, and we solve for a to 54 for a. Then we insert a as 54 for 2a to get 54*2=108 degrees.

Sorry i'm asking for so much help tonight/morning, i just rlly need to get this finished and i still don't completely understand this. Plz help me with this? Thanks in advance
Answer:
Read below
1. 270
2. 277
Step-by-step explanation:
I'm not too sure which answer you're looking for but I'll try to answer all of them :).
First of all, we can consider them in percentage form first.
If the first sale price is marked down by 30%, it is now 70%.
For the second, the price is marked down by 20% first, so 80%.
And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.
As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price
Now we move on to the actual prices.
First one is 70% of the original price, 70% of $385 is $269.5.
Second one is 72% of original price, 72% of $385 is $277.2
Don't forget to round to the nearest dollar!
