Coin a is 33 and coin b is 11

Step-by-step explanation:

Answer:

B = 11

A =33

Step-by-step explanation:

A = 3B

A+B = 44

Substitute the first equation into the second equation

3B + B = 44

Combine like terms

Divide by 4

4B /4 = 44/4

B = 11

A = 3B

A = 3*11

Answer:

[tex]\huge\boxed{No \ solutions}[/tex]

Step-by-step explanation:

Our first goal is to transform these words into numbers for an expression.

Let's break it down.

-7 times a number

We'll assume that the number is [tex]n[/tex]. -7 times a number can be represented as [tex]-7n[/tex].

8 times the sum of the number and 1

We can break this complex statement down.

8 times the sum of the number and 1

The sum of the number and 1 will be [tex]n+1[/tex]. 8 times that will be [tex]8(n+1)[/tex]. Since it says at the beginning the sum of, we add [tex]8(n+1)[/tex] to [tex]-7n[/tex].

[tex]-7n + 8(n+1)[/tex]

Is the same as the number minus 7.

"Is the same" means we use an equal sign. The number minus 7 will be [tex]n-7[/tex]. So we get [tex]-7n + 8(n+1)=n-7[/tex]

Now we can solve for n by reversing the equation until we have n isolated on one side.

[tex]-7n + 8n + 8 = n-7[/tex]

[tex]n + 8 = n-7[/tex]

[tex]8 = -7[/tex]

We end up with 8 = -7. This is not possible. Therefore, there are no real values of x that satisfy this equation.

Hope this helped!

Answer (the system of equations input doesn't work, so there is no brace):

x = 1.5y

x + y =800

Step-by-step explanation:

First, identify the vital information:

- 800 total students

- 1.5 times as many boys as girls

So, if x = number of boys and y = number of girls, we can agree that:

x = 1.5y

And because there are 800 kids in total, we can agree that:

x + y = 800

There are 320 girls and 480 boys. (see below)

Since you have the value of x, 1.5y, you can plug-in the value:

x + y = 800

1.5 + y = 800

2.5y = 800

y = 320 girls

Plug-in the y-value into the equation for the number of boys:

x = 1.5y

x = 1.5(320)

x = 480 boys

To double-check:

320 + 480 = 800 ☺

Step-by-step explanation:

Answer: y = 1/4x + 1.25 ?? OR y = -4x + 23

Step-by-step explanation:

y = mx + c

3 = 1/4 (5) + c

3 = 1.25 + c

-1.25 from both sides  

c = 1.75

y = 1/4x + 1.75

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

perpendicular gradient = -4

y = -4x + c

3 = -4(5) + c

3 = -20 + c

+20 to both sides

c = 23

y = -4x + 23

Answer:

1.5 ft remaining

$30 per ft of sheet

Sheet metal costs $30 per square foot.

Step-by-step explanation:

6.4x - 4.9x = 45

           1.5x = 45

                x = 30

6.4 - 4.9 = 1.5 ft remaining

$45 : 1.5 = $30 per ft of sheet

Answer: x = {1 , 5 , 7}

Step-by-step explanation:

We have x^3 - 13x^2 + 47x - 35 = 0.

Taking -13x^2, we can split it up into -x^2 - 12x^2

Taking 47x, we can split it up into 12x + 35x

Putting these into the original equation, we have:

x^3 - x^2 - 12x^2 + 12x + 35x - 35 = 0

From this you can see that we have 3 pairs of terms that we can easily factor. From the first pair we can factor x^2, from the second we can factor -12x, and from the third one we can factor 35.

1. (x^3 - x^2)  = x^2 (x - 1)

2. (- 12x^2 + 12x) = -12x (x - 1)

3. (35x - 35) = 35 (x - 1)

Putting them back into the equation we have:

x^2 (x - 1) - 12x (x - 1) + 35 (x - 1) = 0

               (x^2 - 12x + 35) (x - 1) = 0

To find the roots, we can set (x - 1) = 0 and  (x^2 - 12x + 35) = 0.

x - 1 = 0

    x = 1 (First root)

x^2 - 12x + 35 = 0

Factoring using the Sum-Product Rule:

Sum of -12, Product of 35 --> -7 and -5

x^2 - 12x + 35 = 0

  (x - 7) (x - 5) = 0

We can see that x = 7 and x = 5.

So the solution set it x = {1 , 5 , 7}

The solution set will be {1,5,7}

Zero of a function is the root of the function for which the function value of that root will be zero.

If a is the zero of function f(x)=0 then f(a)=0.

So according to question,

the equation is

x³-13x²+47x-35=0

spilting -13x² as -x²-12x² and 47x as 12x+35x

⇒x³-x²-12x²+12x+35x-35=0

⇒x²(x-1)-12x(x-1)+35(x-1)=0

taking (x-1) common from each term

⇒(x-1)(x²-12x+35)=0

In another way, as 1 is zero of x³-13x²+47x-35=0

then (x-1) is one factor of x³-13x²+47x-35=0

another factor will be x³-13x²+47x-35/(x-1)=x²-12x+35

for which we can write the equation x³-13x²+47x-35=(x-1)(x²-12x+35).

⇒(x-1)(x²-5x-7x-35)=0

⇒(x-1)(x(x-5)-7(x-5))=0

⇒(x-1)(x-5)(x-7)=0

⇒x-1=0  or  x-5=0  or  x-7=0

⇒x=1   or   x=5   or   x=7

Therefore The solution set will be {1,5,7}

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following annual growth rates:

land/food = - 1%

food/kcal = 0.5%

kcal/person = 0.1%

population = 1.5%

Σ annual growth rates = (-1 + 0.5 + 0.1 + 1.5)% = 1.1% = 0.011

Exponential growth in Land :

L = Lo * e^(rt)

Where Lo = Initial ; L = increase after t years ; r = growth rate

Time for amount of cultivated land to double

L = 2 * initial

L = 2Lo

2Lo = Lo * e^(rt)

2 = e^(0.011t)

Take the In of both sides

In(2) = 0.011t

0.6931471 = 0.011t

t = 0.6931471 / 0.011

t = 63.01 years

Land per unit of food at t = 63.01 years

L = Fo * e^(rt)

r = growth rate of land required to grow a unit of food = 1% = 0.01

L/Fo = e^(-0.01* 63.01)

L/Fo = e^(−0.6301)

= 0.5325385 = 0.53253 * 100% = 53.25%

Land per unit now takes (100% - 53.25%) = 46.75%

Step-by-step explanation:

Get rid of the parenthesis then combine like terms

The probability is 0.771.

The answer rounded to the nearest thousandth.

The probability that the Yankees would score 5 or more runs when they win the game can be calculated by using the formula for conditional probability. It can be determined by dividing the probability that the Yankees win and score 5 or more runs by the probability that the Yankees win.

The formula for conditional probability is:

Conditional Probability = P(A and B) / P(B)Where A and B are two events.

In this case, the two events are the Yankees win and the Yankees score 5 or more runs. So, the probability that the Yankees would score 5 or more runs when they win the game is:
P(Yankees score 5 or more runs | Yankees win) = P(Yankees win and score 5 or more runs) / P(Yankees win)Using the given values:

P(Yankees score 5 or more runs | Yankees win) = 0.44 / 0.57 = 0.771.

This means that when the Yankees win a game, there is a 77.1% chance that they would score 5 or more runs.

The answer is rounded to the nearest thousandth.
