Answer:

Answer:

Cost of one (chicken) = $ 8

Cost of one (duck) = $ 5

Explanation: heyy there :)

Let c be (chickens) and d be (ducks)

Given :

50 �+ 30 � = $ 550

Dividing both sides by 10,

5 + 3 = 55 Eqn (1)

44 + 36 = $ 532

11 + 9 = 133 Eqn (2)

Multiply Eqn (1) by 3 to eliminate y term when subtraing Eqn (1) from (2).

Then a Eqn (1) becomes, 15 + 9 = 165 Eqn (3)

Subtracting Eqn (2) from (3),

(15 - 11) = (165 - 133)

4 = 32 or = $ 8.

Substituting value of in Eqn (1),

(5 * 8) + 3 = 55

3 = 55 - 40 = 15

= 15 / 3 = $ 5

Lilit [14]

Answer:

The sailboat moves southward at a force of 1000 Newton

Explanation:

The sailboat is moving south at 2500 newtons. The opposite force is only 1500 newtons, which is less than 2500 units. The greater force cancels out the lesser force. In order for the boat to be stopped or pushed back, the water and air resistance would of had to of been greater than or equal to 2500 Newtons. Because of this opposite force, the boat continues to move but with a lesser amount of force. You can use subtraction to find the remaining force the boat has.

2500 Newtons - 1500 Newtons = 1000 Newtons

Which point marks a peak?

Irina18 [472]

Answer with Explanation:

The peak, trough, recession and recovery are stages of the "Business Cycle." They can be represented in a line graph as points that represent individual stages. Each can tell what a country's economy is experiencing in terms of fluctuations happening in economic activities.

The peak is that highest point in the graph. It means that the economy is producing the maximum output that it is allowed to do so.

The trough is the lowest point in the graph. This marks the end of depression. This means that soon, the economy will try to recover.

The recession is that point on the graph that goes down following the peak. This is a period of economic decline or contraction. Here, the production decreases.

The recovery is that point on the graph that goes up following the trough. This stage is marked by increase in demand and production. It is considered to be the end of the business cycle.

kykrilka [37]

Answer:

B. take classes in high school that will give her college credit.

Explanation:

This is one of the ways in which Sheila might be able to attend college. By taking some classes in high school that will give her college credit, Sheila would most likely lessen the load of classes that she has to take in college. This will allow her to take less classes in college each year, reducing the fees she pays. Otherwise, she could also choose to take more classes each year, but stay in school for less time. Either way, her tuition costs are likely to be lower.

erik [133]

Answer:

13.14 litres

Explanation:

The question is incomplete. Here is the complete question.

Dwight was told by his mystic guru that a special medicine would help him gain superhuman strength to fight bears. The instructions say “Take 2 drops per 10 pounds of body weight per day, in 4 doses a day.” Dwight weighs 180 lbs. There are approximately 20 drops in 1 mL. How many liters of the medicine should Dwight buy to have a supply for the next five years.

If Dwight takes 2 drops per 10 pounds of body weight per day and he weighs 180 pounds, the total drop per 180 pounds will be expressed as;

2drops = 10pounds

x drop = 180pounds

Cross multiply

10x = 360

Divide both sides by 10

10x/10 = 360/10

x = 36 drops

Therefore he uses 36drops per day (This is for one dose)

Since he is to take 4doses of it in a day, the total amount of drops he will take in a day will be 4×36 = 144drops/day

Before we can calculate the amount of litres he will need for the next 5years , we will have to know the total drops he will need for that 5 years first. This is shown below;

Converting 5years to days:

1year = 365days (excluding a leap year)

5years = 5×365 = 1,825 days

Since 1day = 144 drops

1,825 days = x drops

Cross multiply

x = 1825 × 144

x = 262,800 drops

This means that he will need 262,800 drops for 5years

If there are approximately 20 drops in a ml

262800 drops will be in (262800/20)ml

262800/20 = 13140mL

Convert 13140mL to litres

13140mL = 131400× 10^-3 Litres

13140mL = 13140/1000 litres

13140mL = 13.14Litres

Hence Dwight will have to buy 13.14litres of the medicine to have a supply for the next five years.
