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?

Answers

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

Answers

The correct answer is B!

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

Solve the system of equations by the addition method.

Answer:

700,000 >70,000

Step-by-step explanation:

To break it down:

the value of each number is the following:

first 7: 700,000 , second 7: 70,000, 1: 1000, 5: 500, 4: 40, 8:8

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

Answers

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.

Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fish is swimming at −3 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water? The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4. The fish is closer to the surface of the water because |+4| = 4 and − |−3| = −3, and −3 < 4. The sea gull is closer to the surface of the water because |+4| = −4 and |−3| = −3, and −3 > −4. The sea gull is closer to the surface of the water because |+4| = 4 and − |−3| = 3, and 4 > 3.

Find the total cost with tip.
Mr .Smith goes to eat for his son's birthday. The total bill is $56.50. If Mr. Smith leaves a 22% tip. What is the tip amount? What is the total cost of the meal with tip included?

Answers

Finding the tip amount:
(56.5)(22)=1,243
1,243/100=12.43
The tip amount is $12.43.
Finding the total cost:
56.50+12.43=68.93
The total cost of the meal with tip included is $68.93.
56.50 * .22 = 12.43
56.50 + 12.43 = $68.93

What is the measure of the exterior angle? Show all steps.

Answers

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.

The answer is 108 degrees

8.067 ; hundredths Round each decimal to the place indicated.

Answers

Answer:

8.06

Step-by-step explanation:

Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.

for example if the number was 1.2345      5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.

Which equation best represents the relationship?
1. y = 1/2x + 2

2. y = 1/2x + 1

3. y = x + 2

4. y = 2x + 1

Answers

Answer:

It's the 4th one

Step-by-step explanation:

.................................

The answer would be 1. This is because if you do this equation for every row in the table it would always equal y. 1/2x (x divided by 2) would always equal 2 less than y. There is no unit rate in this problem because it is not proportional.
