the combined area of two squares is 45 cenimeters. Each side of one square is twice as long as a side of the other square. What is the length of each side of the larger square

The expression (2−2n)−(5n−27) is not positive for any natural values of n, because when simplified, the inequality n < −(25/7) suggests n would need to be a negative value, which is not possible for natural numbers.

To determine for which natural values of n the expression (2−2n)−(5n−27) is positive, we must solve for the values of n that make the expression greater than zero. Simplifying, we get:

2 − 2n − 5n − 27 > 0

−7n − 25 > 0

Since we have a negative coefficient for n, as n increases, the value of the left side of the inequality decreases. To find the values of n that satisfy the inequality, we isolate n:

−7n > 25

n < −(25/7)

Considering n must be a natural number (positive integer), there are no natural values of n that satisfy the inequality, as natural numbers are always non-negative, and our inequality requires n to be less than a negative number.

Answer:

Step-by-step explanation:

The definitions of rigid-motion transformations need to be precise as they entail more than physical descriptions of motions. They have unique mathematical definitions and are important for understanding and interpreting real-world movements and physical phenomena.

The definitions of each rigid-motion transformation, namely slides (translations), flips (reflections), and turns (rotations), need to be more precise because they are not solely about the physical manifestation of the motion. These transformations have distinct mathematical underpinnings. For instance, a translation involves moving the figure along a specified direction and distance in a straight line, without changing the orientation of the figure. A reflection involves 'flipping' the figure over a line of reflection, altering its orientation but not its shape or size. A rotation involves turning the figure around a specified point for a given angle.

Moreover, in both rotational and translational motion - two forms of rigid-body motion, there are accurate variables such as displacement, velocity, and acceleration related to translational motion and the corresponding angular variables in rotational motion. These specific definitions are crucial for the mathematics behind movement and interpreting the world around us. Understanding such concepts can also aid in studying physical phenomena as diverse as a spinning ballet dancer or a rotating planet.

The correct answer option is B. (5, 8).

Step-by-step explanation:

We are given the following coordinates of the vertices of a square and we are to find the coordinates of its fourth vertex:

[tex] ( - 1 , 2 ) , ( - 1 , 8 ) , ( 5 , 2 ) [/tex]

We know that all four sides of the square are equal so the vertices are equidistant from each other.

So the fourth vertex will be (5, 8).

The answer is b. (5,8)

Answer:

x=3

y=21

Step-by-step explanation:

To use substitution method, first we need to decide which variable solve first, either x or y.

Here we decide to start by 'y' using equation y=x+18, which is already solved for 'y'

That same equation is then substitute into the first equation:

x+18= 10x-9

From here, we isolate 'x' variable and grouping terms, we have this:

27=9x

Resulting x=3

Now, we can use the above result in the second equation (y=x+18)

Leading to y=3+18=21.

Answer:

6 miles

Step-by-step explanation:

Let the route length be r.  The distance the cyclist has already covered is then (5/7)r + 40.  This plus 0.75r - 118 must = r, the length of the entire route.

Then:

(5/7)r + 40 + (3/4)r - 118 = r

The LCD of the fractions 5/7 and 3/4 is 28.  We thus have:

(20/28)r + 40 + (21/28)r - 118 = r, or

(41/28)r - 78 = (28/28)r

Combining the r terms, we get 13r = 78, and so r = 78/13 = 6.

The cyclist's bike route is 6 miles long.

Answer:

x = 20

∠B = 92

∠C = 40

Step-by-step explanation:

im pretty sure

Answer:

x = 20. ∠B = 92° and ∠C = 40°

Step-by-step explanation:

Angles of a triangle are ∠A = 48°, ∠B = (6x - 28)° and ∠C = (2x)°

Since sum of all the angles of the triangle is 180°

So ∠A + ∠B + ∠C = 180°

48° + (6x - 28)° + (2x)° = 180°

48 + 6x - 28 + 2x = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = [tex]\frac{160}{8}=20[/tex]

Now ∠B = (6x - 28) = 6×20 - 28

∠B = 120 - 28 = 92°

And ∠C = 2x° = 2×20 = 40°

Therefore, x = 20. ∠B = 92° and ∠C = 40° is the answer.

Perpendicular Lines

Answer: the answer is 2

Step-by-step explanation:

12 x 2 is 24

12 x 3 is 36

so it goes into 32, 2 times.

Final answer:

12 goes into 32 a total of 2 full times with a remainder of 8, which can also be expressed as 2 and 2/3 times. The calculation is done using long division.

Explanation:

The question asks how many times does 12 go into 32. This is a division problem where you need to divide 32 by 12. To calculate this, you can use long division. Dividing 32 by 12 gives you 2 with a remainder of 8, since 12 times 2 is 24 and 32 minus 24 leaves 8. Therefore, 12 goes into 32 2 full times with 8 left over, or 2 remainder 8.

Another way to express this is in terms of decimal or fractions. Since 8 is 2/3 of 12, you can also say that 12 goes into 32 2 and 2/3 times. However, if you are strictly looking for how many full times 12 can divide into 32 without considering fractions, the answer is simply 2.

Answer:

Center : (2,-3)

Radius : sqrt(6)

Step-by-step explanation:

Rewrite this is standard form to find the center and radius.

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

From this, we can determine that the center is (2,-3) and the radius is sqrt(6)

Answer:

center is (2,-3)

Radius =[tex]\sqrt{6}[/tex]

Step-by-step explanation:

[tex]2x^2-8x+2y^2+12y+14=0[/tex]

To find out the center and radius we write the given equation in

(x-h)^2 +(y-k)^2 = r^2 form

Apply completing the square method

[tex]2x^2-8x+2y^2+12y+14=0[/tex]

[tex](2x^2-8x)+(2y^2+12y)+14=0[/tex]

factor out 2 from each group

[tex]2(x^2-4x)+2(y^2+6y)+14=0[/tex]

Take half of coefficient of middle term of each group and square it

add and subtract the numbers

4/2= 2, 2^2 = 4

6/2= 3, 3^2 = 9

[tex]2(x^2-4x+4-4)+2(y^2+6y+9-9)+14=0[/tex]

now multiply -4 and -9 with 2 to take out from parenthesis

[tex]2(x^2-4x+4)+2(y^2+6y+9)+14-8-18=0[/tex]

[tex]2(x-2)^2 +2(y+3)^2 -12=0[/tex]

Divide whole equation by 2

[tex](x-2)^2 +(y+3)^2 -6=0[/tex]

Add 6 on both sides

[tex](x-2)^2 +(y+3)^2 -6=0[/tex]

now compare with  equation

(x-h)^2 + (y-k)^2 = r^2

center is (h,k)  and radius is r

center is (2,-3)

r^2 = 6

Radius =[tex]\sqrt{6}[/tex]

Answer:

(3, 2)

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

3x + y = 11 → (2)

Substitute y = 2x - 4 into (2)

3x + 2x - 4 = 11

5x - 4 = 11 ( add 4 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Substitute x = 3 into (1) for corresponding value of y

y = (2 × 3) - 4 = 6 - 4 = 2

Solution is (3, 2)

Answer:

Step-by-step explanation:

this system not equation :

y=2x-4 ....(1)

3x+y=11​....(2)

put the value of y by (1)  in to (2) :

3x+2x-4 = 11

add4 : 3x+2x =15

5x=15

x=15/5 = 3

but: y = 2x-4

so :  y =  2(3) -4

y = 6-4=2

Answer:

He can make 9 Muffins

Step-by-step explanation:

16*2.25=36

51.75 - 36=15.75  Subtract the total number of selling he made by how much he made with the brownies

15.75/1.75=9 Divide the number you got after subtracting by by how many he  is going to sell each of then

Omar made $36 from selling brownies. He made $15.75 from selling muffins, and since each muffin cost $1.75, he therefore sold 9 muffins at the bake sale.

To solve this problem, we must first find the total money Omar made from selling brownies. We do this by multiplying the price of each brownie ($2.25) by the number of brownies sold (16), which gives $36. Then we subtract this total from the total money Omar made ($51.75) to find out how much money he made from selling muffins, which is $51.75 - $36 = $15.75.

Next, we divide this amount by the price of each muffin ($1.75) to find out the number of muffins sold, as follows: $15.75 ÷ $1.75 = 9.

So, Omar sold 9 muffins at the bake sale.

Final answer:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle.

Explanation:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle. In this case, if the period of the sinusoidal function is 18, then the function will complete one full cycle every 18 units of time. This means that after 18 units of time, the function will have returned to its starting point.

For example, if we have a sinusoidal function f(x) = sin(x), then the period of this function is 2π, because it takes 2π units of time for the function to complete one full cycle. In general, the period of a sinusoidal function can be calculated using the formula T = 2π/ω, where T is the period and ω is the angular frequency.

Answer:

Step-by-step explanation:

0.6y + 1.2 = 0.3y + 0.9 + 0.8y

0.3 = 0.5y

1.67 = y

Answer:

0.6y+1.2=0.3y-0.9+0.8y

       +0.9=        +0.9

0.6y+2.1=1.1y

-0.6y=-0.6y

2.1=0.5

y=4.2

Step-by-step explanation:

First you want to isolate the variable to one side which is exactly why I added 0.9 to both sides. Then you want to combine like terms. By combining like terms you can now distribute the variable by the value remaining, which led to me getting y=4.2

The correct answer is c) C(4) = 398, which appropriately links the cost of manufacturing 4 pairs of sunglasses ($398) with the function C(x).

The function C(x) represents the cost to manufacture x pairs of sunglasses.

Given that it costs $398 to manufacture 4 pairs, we can substitute these values into the function to find which statement is accurate.

The logic behind this is simple: C(x) is typically understood to be the cost associated with producing x units.

Therefore, when x is the number of units produced, C(x) is the total cost to produce those units.

Substituting 4 into the function C(x) would give us the total cost for 4 pairs of sunglasses.

Thus, we can say C(4) = 398. This matches response option c), which states that C(4) = 398, and is therefore true.

Response options a), b), and d) all incorrectly mix up the inputs and outputs of the cost function and therefore can be disregarded.
