You have a combination lock with 3 secret digits. Find the 3 correct digits using the following clues and enter your answer below.

Answers

The first clue only tells us that there is one digit that is in the right place, so it could be any one of the following.

The second one tells us that one of the digits is right but in the wrong place, we still cannot confirm if 5 is the number we are talking about.

The fourth clue says that all the numbers are incorrect, so the digits are 2, 5, 0 or 1, now we must find out the correct order.

From clues 3 and 5 we can assume that 0 is one of the digits and that it comes first.

We will discard the number 5 because in clue 3 they talk about 2 correct digits, we already know that 0 is one and we choose 2 instead of the number five because of clues 1 and 2, which talk about only one digit in the correct place but in both of them the 5 remains in the same place.

The 3 digists are: 1, 0 and 2

The correct order is 012

Now, 9 and 51 are not compatible because 51 cannot divide 9 without a remaider.

The compatible number with 9 that is close to 51 is 54.

Hence,

Jack is buying groceries. He decides to buy 50 total frozen entrees. He buys nothing but Burritos andHungry-Man Meals. The average price of a Hungry-Man Meal is $3.25 while the average price of a Burritois $2.00. If he spends $150 on all the frozen food, how many Hungry-Man Meals and Burritos did he buy?

Answers

Let x the total of Hungry-Man Meals bought.

let y the total of burritos bought.

He decides to buy 50 total frozen entrees.

x + y = 50

If we solve the equation for x

x = 50 - y

We also know that he spends $150 on all the frozen food.

Therefore:

x Hungry-Man Meals for $3.25

y burritos for $2.00

x(3.25) + y(2.00) = 150

3.25x + 2.00y = 150

Now substituting 50-y from the first equation into the second equation and solve for y:

3.25x + 2.00y = 150

3.25(50-y) + 2.00y = 150

3.25*50 - 3.25*y + 2.00y = 150

162.5 - 3.25y + 2.00y = 150

162.5 - 1.25y = 150

Subtract both sides by 150

162.5 - 150 - 1.25y = 150-150

12.5 -1.25y = 0

Add both sides 1.25y

12.5 -1.25y+1.25y= 0+1.25y

12.5 +0 = 1.25y

Divide both sides by 1.25

12.5/1.25 = 1.25y/1.25

10 = y

Substitute 10 for y in the result of the x equation:

x = 50 - y

x = 50- 10

x = 40

So 40 Hungry-Man meals and 10 burritos Jack bought.

Answers

Answer:

Books in Bookcase = 5/6

Science Books = 1/6

Explanation:

Given:

Total number of books Alissa put in a bookcase;

2/5 history books

1/3 math books

1/10 art books

We can go ahead and determine the fraction of the total number of books that are history, math, or art books in the bookcase by adding the given fractions together as seen below;

[tex]\frac{2}{5}+\frac{1}{3}+\frac{1}{10}=\frac{12+10+3}{30}=\frac{25}{30}=\frac{5}{6}[/tex]

So the fraction of the total number of books that are history, math, or art books in the bookcase is 5/6

Let x represent the fraction of the total number of books that will be science.

We can go ahead and determine the value of x by subtracting the fraction of the total number of books that are history, math, or art books in the bookcase from 1;

[tex]x=1-\frac{5}{6}=\frac{6-5}{6}=\frac{1}{6}[/tex]

So the fraction of the total number of books that will be science is 1/6

Surface area = 2260.8 cm²

Explanation

The surface area of a normal sphere is given as

Surface area = 4πr²

where,

π = pi = 3.14

r = radius of the sphere = 12 cm

But this sphere has the middle of the sphere as part of the surface too

Surface area = 4πr² + πr² = 5πr²

Surface area = 5 (3.14) (12²)

Surface area = 2260.8 cm²

The equations in the red box I need to use substitution. Explaining the steps as I go.

Answers

We are given the following system of equations:

[tex]\begin{gathered} y=-x^2+63x-790,(1) \\ y=3x+10,(2) \end{gathered}[/tex]

We will substitute the value of "y" from the first equation into the second equation:

[tex]-x^2+63x-790=3x+10[/tex]

Now we subtract "3x" from both sides:

[tex]-x^2+63x-3x-790=10[/tex]

Adding like terms:

[tex]-x^2+60x-790=10[/tex]

Now we subtract 10 from both sides:

[tex]-x^2+60x-790-10=0[/tex]

Adding like terms:

[tex]-x^2+60x-800=0[/tex]

Now we multiply by -1 on both sides of the equation:

[tex]x^2-60x+800=0[/tex]

Now we factor in the left side. We need two numbers that when multiplied the product is 800 and their algebraic sum is -60. Those numbers are -40 and -20. Therefore, we get:

[tex](x-40)(x-20)=0[/tex]

Now we set each factor to zero:

[tex]\begin{gathered} x-40=0 \\ x=40 \end{gathered}[/tex]

For the next factor:

[tex]\begin{gathered} x-20=0 \\ x=20 \end{gathered}[/tex]

These are the two values of "x" for the solution. To get the corresponding value of "y" we substitute in the second equation. Substituting the first value we get:

[tex]\begin{gathered} y=3(40)+10 \\ y=120+10 \\ y=130 \end{gathered}[/tex]

Now we substitute the second value:

[tex]\begin{gathered} y=3(20)+10 \\ y=60+10 \\ y=70 \end{gathered}[/tex]

Therefore, the solutions of the system are:

[tex]\begin{gathered} (40,130) \\ (20,70) \end{gathered}[/tex]

Hello there. To solve this question, we need to pay attention to the data given by the question and set up an equation for the amount of rabbits in that colony.

In the year 2000 there were 1200 rabits in a colony, and it was observed that their population was increasing at a rate of 21% each year

For this type of question, we call f(x) the function that shows the population in a certain time x.

This function varies directly to the initial population and grows exponentially according to the rate .

Thus, we have that f(x) = P0 * (1+r)^x

In this case, P0 = 1200 and r = 0.21 (21% converted into decimals)

f(x) = 1200 * (1 + 0.21)^x

f(x) = 1200 * 1.21^x

This is the function that models the population of this colony for a year x.

To find how many rabbits you'll have in the year 2007, plug in x = 7

f(7) = 1200 * 1.21^7

Calculate the value

f(7) = 1200 * 3.797 = 4556

In which year will the population be equal to 5000

Making f(x) = 5000, we solve for x

5000 = 1200 * 1.21^x

Divide both sides of the equation by 1200

25/6 = 1.21^x

Take the natural log on both sides of the equation

ln(25/6) = ln(1.21^x)

Apply the logarithm power rule: log(a^b) = b * log(a)

ln(25/6) = x * ln(1.21)

Rewriting 1.21 as 121/100 = (11/10)², we get:

ln(25/6) = 2x * ln(11/10)

Divide both sides of the equation by a factor of 2ln(11/10)

x = ln(25/6)/(2ln(11/10)) approx. 7.4867 years

Rounding up to the next year, x = 8 years.

A =  ( Area of semicircle including side walk ) - ( Area of semicircle without side walk )

radius of smaller semicircle = 10 ft and radius of larger semicircle = 10 + 3 = 13 ft

A = [ ( 3.14 * [tex]13^{2}[/tex] ) / 2 ] - [ ( 3.14 * [tex]10^{2}[/tex] ) / 2 ]

            = ( 530.66 - 314 ) / 2

              = 108.33 [tex]ft^{2}[/tex]

Since we take walk on both sides , we will multiply it with 2

A = 2 * 108.33

A = 216.66[tex]ft^{2}[/tex]

One side of bigger rectangle = 20 + 3 + 3 = 26 ft

A = area of rectangle - area of square
