grandpa has some cows and ducks in his farm. all in all there are 8 heads and 26 legs, how many cows and ducks are in there? solve this using factoring, finding multiples and divisibility rules
Answer:
5 cows and 3 ducks
okay well there are 8 heads and each animal has a head meaning that there are a total of 8 organisms in total. Cows have 4 legs and ducks have 2. Lets say that c is cows and d is ducks. You would have the equations ...
c+d=8
4c+2d=26
well d techniacally = 8-c, so plug in (8-c) for the value of d
4c+2(8-c)=26. Distribute to get
4c+16-2c
and then add like terms. Soy ou would get
2c+16=26.
then just isolate the variable but subtracting 16 from both sides and dividing 2 on both sides. The answer you would get is that c=5 so there are 5 cows. Plug in 5 for c so you get 5+d=8 and tadaaaa you subtract 5 from both sides to get that there are 3 ducks.
hope this helps :)
Kenya has 2 hours to work a 100 problem math test at what rate must she work in order to finish in 2 hours A. 0.83 B. 1.23 C. 1.41 D. 1.35
Answer:
A 0.83
Step-by-step explanation:
2 Hrs = 120 Minutes
100 : 120 = 0.83 minutes per questions
Kenya must complete 0.83 questions per minute in order to finish the test in two hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Kenya has 2 hours to work on a 100 problem math test.
We know, 2 hours is equal to 120 minutes.
Therefore, The rate per minute at which she must complete one question in order to complete it in two hours is,
= (100/120).
= 0.83.

What is the image of (3, 6) when it is translated along the horizontal vector -2,0?
Answer: (1,6)
The vector <-2,0> means we shift the input point two units to the left.
This is the same as writing the rule [tex](x,y) \to (x-2,y)[/tex]
Subtract 2 from the x coordinate. The y coordinate stays the same.
After the translation the point becomes P'(1, 6).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the rightGiven is a coordinate point (3, 6).
The horizontal vector is given by -
A = - 2i + 0j + 0k
A = - 2j
When the point is translated along the vector, then, we can write -
P(3, 6) → P'(3 - 2, 6) → P'(1, 6)
P'(1, 6)
Therefore, after the translation the point becomes P'(1, 6).

Answer:
B. (-infinity, 1)
Step-by-step explanation:
Remember that domain is left to right, and range is down to up.
Question asks to find where the domain is increasing
Increasing means when the line increases
look left, the line extends infinitely in the negative direction: -infinity
There is a discontinuity at 1, and then the line decreases. So that would be the second point
The interval at which the domain is increasing is

∠A and ∠B are vertical angles with m∠A=x and m∠B=4x−30.
What is m∠A?
Answer:
m<A=10
Step-by-step explanation:
I left the image below to show my work of how i got to that answer. I hope this helps!
We know vertical angles have same measure!
Thus!
A = B
=> X = 4X -30
=> 3X = 30
=> X = 10
Thus measure of angle A is 10°The linear parent function is f(x)=

You purchase a burrito for $8.39 and a juice for $2.25. You pay for both items with a $10 bill and a $5 bill. Complete a verbal model for the problem. Then find how much change you receive.
Answer:
You will get $4.36 back.
Step-by-step explanation:
You have to total the cost of the food and drink.
8.39 + 2.25 = 10.64
You give your total money to the cashier to pay for your goods.
10 + 5 = 15
The cashier will give you the refund or change back.
15 - 10.64 = 4.36
The quotient of a number and 3 minus two is at least -12.
Step-by-step explanation:
The problem would translate to this:
[tex]\frac{x}{3} -2 \geq -12[/tex]
Then add 2 to both sides.
[tex]\frac{x}{3}\geq -10[/tex]
Then multiply both sides by 3.
[tex]x\geq -30[/tex]

How many ways are there to make change for $3? (Utilize all forms of US currency, such as Silver dollars, half dollars, quarters, nickels, & pennies.) Is there a specific formula to calculate this?
Answer:
300 pennies. 12 quarters. 6 half dollars. 3 silver dollars. 60 nickles. 30 dimes.
Step-by-step explanation:
Pennies have a value of .01 so we add that to equal 300. For three dollars we need 12 quarters. 300 divided by the value of the quarter which is .25 cents. We have six half dollars (we divide 300 by the value of the half dollar). We would need 3 silver dollars since each is worth a dollar each. We would need 30 dimes (300 divided by 10). Finally, we would need 60 nickels (300/5 = 60).
