Answer:

y = - 3

Step-by-step explanation:

To find the value of y, substitute x = 3 into the equation, that is

y = - 2(3) + 3 = - 6 + 3 = - 3

Answer:

Jamie: His inequality would look like this:  25x >= 600

Stella: Her inequality would look like this: 15y >= 600

Her limitations would be listed as: y=40

Yep. Stella has plenty of money by baking 40 pies; $600.

We can back that up by breaking this down. So. We know that it cost $600 to pay upfront and Jamie makes $25 per car he washes. Stella would make $15 for every pie she baked. So simply, let x represent the number of cars Jamie washes. Let y represent the number of pies Stella makes. Easy.

Since the cost for washing one car is $25

Now, in order to sign up for the trip, money obtained from car washing must be greater than or equal to $600. We know that. Now, lets see their profit margins.

Since the cost for making one pie is $15

Therefore, the cost of making y pies is 15y.

Now, in order to sign up for the trip, money obtained from pie making must be greater than or equal to $600 so with that being the case... 15y>=600

We all know the maximum number of pies that Stella can make is 40. So, the value of can't exceed 40 and must be less than or equal to 40. So.... y<=40

Bam.

In order to sign up for the trip, Stella's total earning must be at least $600. So, is the minimum condition for signing up for the trip. Now, let us solve the above equation for . So our end project looks like this: 15y = 600 y = 600/15 = 40

The minimum number of pies required for signing up for the trip is 40 and luckily that's the maximum supply Stella has for pies. Therefore, she can sign up for the trip by making all the 40 pies and earning a total of 600 dollars.

Answer: ABC is isosceles

Step-by-step explanation:

The coordinate of points given are:

A(1,-4)

B(-1, -2 )

C ( -2 , -5 )

For ABC to be isosceles , then AB must be equal to BC or AB = AC

The next thing to do  is to find the value of AB , BC and AC using the formula for finding distance between two points which is given by:

D = [tex]\sqrt{(x_{2}-x_{1})  ^{2}+(y_{2}-y_{1})  ^{2}}[/tex]

Calculating AB first , we have

[tex]\sqrt{(-1-1)^{2}+(-2+4)^{2}  }[/tex]

= [tex]\sqrt{4+4}[/tex]

=[tex]\sqrt{8}[/tex]

Therefore:

AB = [tex]\sqrt{8}[/tex]

Calculating BC , we have :

D = [tex]\sqrt{(x_{2}-x_{1})  ^{2}+(y_{2}-y_{1})  ^{2}}[/tex]

D = [tex]\sqrt{(-2+1)^{2}+(-5+2)^{2}  }[/tex]

D = [tex]\sqrt{10}[/tex]

Therefore:

BC = [tex]\sqrt{10}[/tex]

Calculating AC , we have :

D = [tex]\sqrt{(x_{2}-x_{1})  ^{2}+(y_{2}-y_{1})  ^{2}}[/tex]

D = [tex]\sqrt{(-2-1)^{2}+(-5+4)^{2}  }[/tex]

D = [tex]\sqrt{10}[/tex]

Therefore:

AC = [tex]\sqrt{10}[/tex]

Since AC = BC then triangle ABC is isosceles

Answer:

For the given expression [tex]x^3 = 135[/tex] , the value of x = 5.13

Step-by-step explanation:

Here, the given expression is : [tex]x^3 = 135[/tex]

Now, to solve this given equation,we need to find the suitable value for x.

Solving for x , we get:

[tex]x^3 = 135[/tex]

Taking cube roots both sides, we get:

[tex]\sqrt[3]{(x)^3}  = \sqrt[3]{135} \\\implies (x)^{3 \times \frac{1}{3}}   =  (135)^{\frac{1}{3}} \\[/tex]

But, 135 = 5.13 x 5.13 x 5.13

[tex]\implies 135   =  (5.13)^3\\\implies x^{3 \times \frac{1}{3}} =  (5.13)^{3 \times \frac{1}{3}}\\\implies x  = 5.13[/tex]

Hence, for the given expression [tex]x^3 = 135[/tex], the value of  x = 5.13

Answer:

the other answer was a bit confusing so, 135 divided by 3 is 45, so, x=45

135 divided by 45 is 3 lol.

Answer:

[tex]\frac{17}{26}[/tex]

Step-by-step explanation:

In probability

"AND" means to multiply, and

"OR" means to add

Here, we want probability getting a red card OR a 10 OR a queen. So we find each individual probabilities and ADD.

In a standard deck, there is 52 cards.

P(Red):

half the cards are red and half are black, so there are 52/2 = 26 red cards

Hence

P(Red) = 26/52 = 1/2

P(10):

There are 4 suits with each one having 1 "10" card, so there are FOUR 10s in a deck. So,

P(10) = 4/52 = 1/13

P(Queen):

There are 4 suits with each one having 1 Queen. So in 4 suits, there are a total of 4 Queens. So,

P(Queen) = 4/52 = 1/13

P(Red, or, 10, or, Queen) = 1/2 + 1/13 + 1/13 = [tex]\frac{17}{26}[/tex]

The correct answer is x = 3

The value of x in the equilateral triangle is 3 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the perimeter of any planer figure except a circle is the sum of the lengths of all the sides and we also know that an equilateral triangle has equal sides and equal angles.

∴ We can equate any of the two sides of the given equilateral triangle.

Answer:

1 ¹/₉ hours

Step-by-step explanation:

Let's say L is Larry's speed, C is Curly's speed, and M is Moe's speed.

1 = 2 (L + C)

1 = 1 ⅔ (C + M)

1 = 1 (L + C + M)

Solve the system of equations.  First, simplify the equations:

1 = 2L + 2C

3 = 5C + 5M

1 = L + C + M

Double the third equation and subtract the first equation from it:

2 = 2L + 2C + 2M

1 = 2L + 2C

1 = 2M

M = 1/2

Plugging into the second and third equations, we get:

C = 1/10

L = 2/5

Therefore, the time it takes Larry and Moe together is:

1 = t (L + M)

t = 1 / (L + M)

t = 1 / (2/5 + 1/2)

t = 1 / (4/10 + 5/10)

t = 1 / (9/10)

t = 10/9

t = 1 ¹/₉ hours

It takes them 1 ¹/₉ hours, or 1 hour 6 minutes 40 seconds.

Larry and Moe would take 5/3 hours, or 1 hour and 40 minutes, to build a bookcase together, based on the rates of building individually and in different pairs.

Larry and Curly together build a bookcase in 2 hours. This means that together they have a rate of 0.5 bookcases per hour, since 1 divided by 2 is 0.5. Similarly, Curly and Moe together can build one in 1 2/3 hours, which is the same as 5/3 hours. Therefore, their collective rate is 3/5 bookcases per hour. Larry, Curly, and Moe together can build a bookcase in 1 hour, which means their combined rate is 1 bookcase per hour.

Let's denote the rates of work for Larry, Curly, and Moe as L, C, and M respectively. When working together the sum of their rates equates to the rate at which they finish the job together. Hence:

L + C = 0.5 (Larry and Curly's rate)

C + M = 3/5 (Curly and Moe's rate)

L + C + M = 1 (Larry, Curly, and Moe's rate)

Using the first two equations, we can solve for L and M by substituting the values into the third equation:

L + 3/5 = 1

L = 1 - 3/5 = 2/5

C + 0.5 = 1

C = 1 - 0.5 = 0.5

Now we know that Larry's rate is 2/5 bookcase per hour, and Curly's rate is 0.5 bookcase per hour. We can use Curly's rate to find Moe's rate:

C + M = 3/5

0.5 + M = 3/5

M = 3/5 - 0.5 = 1/5

Larry and Moe's combined rate is L + M = 2/5 + 1/5 = 3/5 bookcases per hour.

To find the time it takes for Larry and Moe to build one bookcase together, we take the reciprocal of their combined rate:

Time = 1 / (L + M) = 1 / (3/5) = 5/3 hours, which is equal to 1 hour and 40 minutes.

Answer:

36 hours - 6,300

24 hours - 4,200

In 36 hours, 6300 quarts of ice cream could be made. The rate per day would be 6300 quarts per day.

350 quarts of ice cream are made in 2 hours. To find out how many quarts could be made in 36 hours, we can set up a proportion: 350 quarts / 2 hours = x quarts / 36 hours. Solving for x gives us 6300 quarts in 36 hours. To find the rate per day, we divide the total quarts made in 36 hours by the number of days: 6300 quarts / 1 day = 6300 quarts per day.

Answer:

C) 6 inches

Answer:

The minimal number for the objective function P =20x+16y is: 780

The value of x then is: 15

and the value of y then is : 30

Step-by-step explanation:

We are given a system of inequalities as:

y is less than or equal to 2x

i.e.          y ≤ 2x--------(1)

x + y is greater than or equal to 45

i.e.      x+y ≥ 45  ------------(2)    

and    x is less than or equal to 30.    

i.e.               x ≤ 30 -----------(3)    

On plotting these inequalities we get the boundary points as:

        (15,30) , (30,60) and (30,15)    

( Since, the optimal solution always exist at the boundary point )

The optimal function is given by:

 Minimize  P = 20x+16y

Hence, at (15,30) we get:

P= 780

at (30,60) we get:

 P= 1560

at (30,15) we get:

P= 840

This  means that the minimal value of the function is 780

and the value exist at (15,30)

Answer:

3 friends

Step-by-step explanation:

The mean age is 27 so 3 friends are above that age.

The average age of the friends is 27. Only two of the friends, both aged 31, are older than the average age.

To find out how many of the friends are older than the average age, we need to first find the arithmetic mean of the ages. We do this by adding up all the ages and dividing by the number of ages. So, (20+31+28+31+25)/5 = 27. Once we have the average, we can see that the ages of 31 and 31 are larger than the average of 27. Therefore, there are 2 friends whose ages are older than the average.

Final answer:

To double the area of the rectangular garden, the dimensions should increase by 5 meters.

Explanation:

To double the area of the rectangular garden, we need to find the increase in dimensions that will result in double the original area. The original dimensions are 5m by 7m, so the original area is 5m x 7m = 35 square meters. To double this area, the new area should be 35 square meters x 2 = 70 square meters. Let's assume the increase in dimensions is 'x'. The new dimensions will be (5m + x) by (7m + x). We can set up the equation:

(5m + x)(7m + x) = 70 square meters

Expanding and simplifying the equation, we get:

35m + 5x + 7x + x^2 = 70 square meters

Combining like terms, we have:

x^2 + 12x + 35 = 70 square meters

Next, we rearrange the equation into standard form:

x^2 + 12x + 35 - 70 = 0

Simplifying further, we get:

x^2 + 12x - 35 = 0

Now we can solve this quadratic equation by factoring or using the quadratic formula. Factoring the equation gives us:

(x + 7)(x - 5) = 0

Setting each factor equal to zero, we have:

x + 7 = 0 or x - 5 = 0

Solving for 'x', we get:

x = -7 or x = 5

Since a negative value doesn't make sense in this context, we can conclude that the dimensions should increase by 5 meters.
