Michael breeds chickens and ducks. Last month, he sold 505050 chickens and 303030 ducks for \$550$550dollar sign, 550. This month, he sold 444444 chickens and 363636 ducks for \$532$532dollar sign, 532. How much does a chicken cost, and how much does a duck cost?
The price of a single chicken is $8 and the price of a single duck is $5 and this can be determine by forming the linear equation in two variables.
Given :
Michael sold last month, 50 chickens and 30 ducks for $550.This month, he sold 44 chickens and 36 ducks for $532.Let the price of single chicken be 'a' and the price of single duck be 'b'. Then the linear equation will be:
[tex]50a + 30b = 550[/tex] --- (1)
[tex]44a + 36b = 532[/tex] --- (2)
Now, solve the equation (1) for 'b'.
[tex]b = \dfrac{550-50a}{30}[/tex]
[tex]b = \dfrac{55}{3}-\dfrac{5a}{3}[/tex] ---- (3)
Now, put the value of 'b' in equation (2).
[tex]44a+36\left(\dfrac{55}{3}-\dfrac{5a}{3}\right) = 532[/tex]
[tex]44a+660-60a=532[/tex]
128 = 16a
a = 8
Now, put the value of a in equation (3).
[tex]b = \dfrac{55}{3}-\dfrac{5\times 8}{3}[/tex]
b = 5
The price of a single chicken is $8 and the price of a single duck is $5.

In January, you deposit $16 in your checking account. Each month, you deposit $15 more than you did the month before. How much money do you deposit in October?
Answer:
$151Step-by-step explanation:
This problem is about a arithmetic sequence, which is obtained by summing a term which is called "difference". In this case, we need to find the tenth term of the arithmetic sequence, because that's the term assigned for October. The formula of an arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex]
Where:
[tex]n=10\\a_{1}=16\\d=15[/tex]
Replacing values, we have
[tex]a_{10}=16+(10-1)15=151[/tex]
Therefore, on October you will have $151 if you deposit $15 more each month, beginning with $16.
Solve for r: d = rt *

Answer is C
A lighthouse cast a shadow that is 36 meters long at the same time , a person who is 1.5 meter tall casts a shadow that is 4.5 meters long . Write and solve a proportion to find the height of the lighthouse
To find the height of the lighthouse, set up a proportion using the lengths of the shadows and solve for h. The height of the lighthouse is 12 meters.
Explanation:To find the height of the lighthouse, we can set up a proportion based on the lengths of the shadows. Let h be the height of the lighthouse. The proportion is:
(h / 36) = (1.5 / 4.5)
Now, we can cross multiply and solve for h:
h = (1.5 / 4.5) * 36
h = 12 meters

A baby weighed 7.25 lb at birth at the end of 8 months , the baby weighed 2 1/2 times its birth weight. how many pounds did the baby weigh at the end of 8 month ?
Answer:
The weight of baby at the end of 8 month is 18.125 lb.
Step-by-step explanation:
Given information:
The weight of baby at birth = 7.25 lb
At the end of 8 months, the baby weighed [tex]2\frac{1}{2}[/tex] times its birth weight.
We need to find the weight of baby at the end of 8 month.
[tex]2\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}[/tex]
The weight of baby at the end of 8 month is 5/2 times of its initial weight.
[tex]\text{Total weight}=7.25\times \frac{5}{2}[/tex]
[tex]\text{Total weight}=18.125[/tex]
Therefore the weight of baby at the end of 8 month is 18.125 lb.

What is the value of a, if a2 – 64 = 0 and a > 0? A) 0 B) 4 C) 8 D) 16
Answer:
C) 8
Step-by-step explanation:
Let's solve for:
[tex]a^2 -64=0\\\\a>0[/tex]
Add 64 to both sides:
[tex]a^2-64+64=0+64\\\\a^2=64[/tex]
Take the square root of both sides
[tex]\sqrt{a^2} = \sqrt{64} \\\\a=\pm 8[/tex]
Therefore, we got two solutions:
[tex]a=8\\\\or\\\\a=-8[/tex]
However, since:
[tex]a>0[/tex]
The only solution is:
[tex]a=8[/tex]

Answer:
The answer is 3 pairs.
Step-by-step explanation:
The flat surfaces that meet at edges are called faces.
The given figure is a cube.
The cube possess six square faces with three meeting at each vertex. In total it has 6 faces, 12 edges, and 8 vertices. Its six faces are arranged in three sets of two parallel faces.
So, there are 3 pairs of parallel faces in a cube.
The dance instructor asks his class for three volunteers to show some new moves. There are twenty people in class and everyone is silent. One girl, Janie looks around the room to see if anyone is going to volunteer first. Then maybe she won't have to volunteer if someone else does. Which term describes why Janie didn't want to volunteer? bystander effect diffusion of responsibility social facilitation conformity
The term that describes why Janie didn't want to volunteer is probably the diffusion of responsibility. I think this is the answer ( and this is the answer I put on my quiz ) because the responsibility does not have to belong to Janie since there are nineteen other students that can volunteer.
Answer: Diffusion of responsibility

A marathon is 26 miles 385 yards long . That is about what 1.4 x10 feet how many feet long is half a marathon
I believe that the correct measurement in feet is 1.4 x 10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
Final answer:
Half a marathon is 69,168 feet in length. To calculate the runner's time for a full marathon at an average speed of 9.5 mi/h, divide the distance (26.2 miles) by the speed, resulting in approximately 2.76 hours or about 2 hours and 45 minutes.
Explanation:
To find the length of half a marathon in feet, we first need to know the length of a full marathon in feet then divide that by 2. Since one marathon is approximately 26.2 miles, we first need to convert miles to feet. There are 5,280 feet in one mile. So, for a full marathon:
26.2 miles × 5,280 feet/mile = 138,336 feet for a full marathon.
Therefore, half a marathon would be:
138,336 feet ÷ 2 = 69,168 feet for half a marathon.
Next, let's look at the question about the marathon runner's time. If a runner averages 9.5 mi/h over a full marathon of 26.2 miles, we can calculate the time taken to run this distance. Time is distance divided by speed, so:
26.2 miles ÷ 9.5 mi/h = approximately 2.76 hours,
which can be converted to minutes: 2.76 hours × 60 minutes/hour = approximately 165.6 minutes or about 2 hours and 45 minutes.
