Use the conversion factor 4 quarts / 1 gallon to convert 5.25 gallons to quarts

Answers

There are 21 quarts in 5.25 gallons.

Answer: 21 quarts

Step-by-step explanation: In this problem, we are asked to convert 5.25 gallons into quarts. To convert gallons into quarts, we use the conversion factor for gallons and quarts.

Conversion factor ⇒ 4 quarts = 1 gallon

Next, notice that we are going from a larger unit "gallons" to a smaller unit "quarts" and when we go from a larger unit to a smaller unit we multiply.

We will multiply 5.25 by the conversion factor which is 4 to get 21 quarts.

Therefore, 5.25 gallons is equal to 21 quarts.

find the greatest common factor of 15x^2y^3 and -20x^3yz

Answers

5x^2y is the greatest common factor

The greatest common factor of [tex]$15x^2y^3$[/tex] and [tex]$-20x^3yz$[/tex] is [tex]$5x^2y$[/tex].

To find the greatest common factor (GCF) of [tex]$15x^2y^3$[/tex] and [tex]$-20x^3yz$[/tex], we need to identify the highest power of each common factor that both terms share.

List the prime factors of each term:

[tex]$15x^2y^3 = 3 \times 5 \times x^2 \times y^3$[/tex]

[tex]$-20x^3yz = -1 \times 2 \times 2 \times 5 \times x^3 \times y \times z$[/tex]

Identify the common factors:

Common factors: [tex]$5$, $x^2$, $y$[/tex]

Find the lowest exponent for each common factor:

For (5), it appears in both terms, so we use the smaller exponent, which is [tex]$5^1$[/tex].

For [tex]$x^2$[/tex], it appears in both terms, so we use the smaller exponent, which is [tex]$x^2$[/tex].

For (y), it appears in both terms, so we use the smaller exponent, which is [tex]$y^1$[/tex].

Multiply the common factors:

[tex]$GCF = 5 \times x^2 \times y = 5x^2y$.[/tex]

So, the greatest common factor of [tex]$15x^2y^3$[/tex] and [tex]$-20x^3yz$[/tex] is [tex]$5x^2y$[/tex].

The sides of an equilateral triangle are increasing at a rate of 10 cm/min. at what rate is the area of the triangle increasing when the sides are 30 cm long?

Answers

Area of a triangle is given by

[tex]Area= \frac{1}{2} ab\sin C= \frac{1}{2} s^2\sin C[/tex]

Since the sides of an equilateral triangle are equal.

Differentiating the area of the triangle, we have:

[tex] \frac{dA}{dt} = \frac{dA}{ds} \cdot \frac{ds}{dt} =(s\sin C) \frac{ds}{dt} [/tex]

where

[tex] \frac{ds}{dt} =10\,cm/min \\ s=30 \, cm[/tex]

[tex]\therefore \frac{dA}{dt} =(30\sin60)\times10=300\sin60=259.8\, cm^2/min[/tex]

Therefore, the rate is the area of the triangle increasing when the sides are 30 cm long is 259.8 cm^2 / min

144 + b^2 =400
B^2 =256
B=16

Answer:

Option B : 16

Step-by-step explanation:

Refer the attached file

Given :

In ΔABC , AB = b , BC = 12 , AC= 20

To Find : value of b i.e. Length of AB

Solution:

Since we are given a right angles triangle so we can use Pythagoras theorem i.e.

[tex](Hypotenuse)^{2} =(Perpendicular)^{2} +(Base)^{2} [/tex] ---(a)

Now in a given triangle AB is Perpendicular , BC is Base and AC is Hypotenuse.

So, putting values in (a)

[tex](AC)^{2} =(AB)^{2} +(BC)^{2} [/tex]

[tex](20)^{2} =(b)^{2} +(12)^{2} [/tex]

[tex]400 =(AB)^{2} +144 [/tex]

[tex]400-144 =(b)^{2} [/tex]

[tex]256 =(b)^{2} [/tex]

[tex]\sqrt{256} =b[/tex]

[tex]16=b[/tex]

Thus the value of b is 6

Hence Option B is correct.

A $360,000 building is depreciated by its owner. the value y of the building after x months is: y = 360,000 – 1,500 x. how many months will it take until it is completely depreciated

Answers

Final answer:

To find when the building will be completely depreciated, you solve for x in the equation y = 360,000 - 1,500x by setting y to 0. The solution is x = 240, meaning the building will be totally depreciated after 240 months or 20 years.

Explanation:

In this case, you are looking to find the value of x (the number of months) when the value of the building (y) becomes 0. The equation given is y = 360,000 - 1,500x. Set y = 0 and solve for x

First, replace y with 0 in the given equation: 0 = 360,000 - 1,500x. Next, move the term with x to the other side by adding 1,500x to both sides, which gives: 1,500x = 360,000.Finally, solve for x by dividing both sides of the equation by 1,500. This gives you: x = 360,000 / 1,500 = 240.

So, the building will be completely depreciated after 240 months or 20 years.

Ali,s dod weighs 8 times as many as her cat.Together, the two pets weigh 54 pounds.HOW much does Ali's dog weigh

Answers

Ali dog = 8units
cat = 1 unit
total = 9 units
9u= 54
1u=6
8u= 48 pounds

There are a few steps in order to get the correct answer.

First you have to look at the facts about what we know:
- her dog is 8 times as much as her cat
- her dog and cat together equal 54 pounds

Now you need to create the equations based on what you know:
Let's say x is her dog and y is her cat

x+y=54 (both dog & cat equal 54)
x=8y (dog is 8 times as much as cat)

Step 1 -
Put in what we know x is for our first equation and solve for y (cat):

8y+y=54 (Combine like terms)
9y=54 (Divide by 9 on each side to get y by itself)
y=6
Now we have solved for y, but we still don't know what x is.

Step 2 -
Put in y into our first equation to solve for x (dog):

x+6=54 (Subtract 6 from both sides to get x by itself)
x=48
Now we have solved for x also. So now we have both x and y.

But to check our work we just have to put the numbers into the original equations:

x+y=54 ----> 48+6=54 (Correct)
x=8y ----> 48=8(6) (Correct)

You now have your final answer. Ali's dog weighs 48 pounds and her cat weighs 6 pounds.

Michael is trying to determine which tennis club to join. If Michael chooses option 2, for which month will his total cost for option 2 be less than his total cost for option 1? A) month 8 B) month 9 C) month 10 D) month 11

Answers

Let us say that m is the number of months. So that the equations for option 1 (O1) and option 2 (O2) are:

O1 = 30 m + 100

O2 = 25 m + 150

TO determine this, we equate O1 and O2 so that:

30 m + 100 = 25 m + 150

5 m = 50

m = 10

So at the 10th month, the cost for both options are equal. So we select month 11.

This is a linear programming problem. When I say "programming", I don't mean computers. This can be done without the use of a computer though I don't recommend doing it by hand.

Let
x = number of trays of corn muffins
y = number of trays of bran muffins

Given info: "baking a tray of corn muffins takes 4 cups of milk and 3 cups of wheat flour"
If we focus on the milk only then baking x trays of corn muffins means we use up 4*x (or simply 4x) cups of milk. Focus now on the wheat flour and it takes 3*x or 3x cups of wheat flour

Also given: "Baking a tray of bran muffins takes 2 cups of milk and 3 cups of wheat flour"
So we use up 2y cups of milk and 3y cups of wheat flour

-----------------

So far we have used 4x cups of milk for the corn muffins plus 2y more cups of milk for bran muffins giving a total of 4x+2y cups of milk used. We only have 16 cups of milk which means we can say this

4x + 2y <= 16

where the "<=" symbol without quotes means "less than or equal to". That inequality above is one of the constraints placed.

-----------------

Another constraint is this inequality

3x+3y <= 15

because
* we use 3x cups of wheat flour for the corn muffins
* we use 3y cups of wheat flour for the bran muffins
* we have a max of 15 cups of wheat flour

-----------------

Additional contraints are:
x >= 0
y >= 0
indicating that we cannot have x or y be negative

-----------------

The four constraints are:
4x + 2y <= 16
3x+3y <= 15
x >= 0
y >= 0

If you graph all of these inequalities and do the proper shading, you'll get what you see in the attached image. Specifically I'm talking about the blue shaded region. This region is known as the feasible region.

Now turn your attention to the red corner points aka the vertices. These points will be plugged into the objective function

P(x,y) = 3x+2y

This represents the profit (in dollars) of making x trays of corn muffins and y trays of bran muffins.
3x = 3*x = profit from just the corn muffins only
2y = 2*y = profit from just the bran muffins only
3x+2y = total profit (selling both corn and bran muffins)

The four corner points are:
A = (3,2)
B = (0,5)
C = (0,0)
D = (4,0)

Plug each of these points into P(x,y) = 3x+2y

-----------------------------

Plug in A = (x,y) = (3,2)
P(x,y) = 3x+2y
P(3,2) = 3*3+2*2
P(3,2) = 13

We earn a profit of $13 if we sell 3 trays of corn muffins and 2 trays of bran muffins

-----------------------------

Plug in (x,y) = (0,5) which is point B
P(x,y) = 3x+2y
P(0,5) = 3*0+2*5
P(0,5) = 10

The profit dropped to $10, so we can ignore point B. So far point A leads to the most profit.

-----------------------------

Plug in point C, which is (x,y) = (0,0)
P(x,y) = 3x+2y
P(0,0) = 3*0+2*0
P(0,0) = 0

The profit drops even further. Ignore this point.

-----------------------------

Plug in point D: (x,y) = (4,0)

P(x,y) = 3x+2y
P(4,0) = 3*4+2*0
P(4,0) = 12

The profit has gone back up but not at the same height as $13 back for point A. So we can cross this off the list too

-----------------------------

The max profit happens at point A which again was
(x,y) = (3,2)
x = 3 ----> selling 3 trays of corn muffins
y = 2 ----> selling 2 trays of bran muffins

----------------------------------------------------------
----------------------------------------------------------
