Start at 39 and create a pattern with the rule subtract 5. What is the third number in the pattern,,?

Answer:

P(1+r) = p(1+0.11)= p+0.11p=1.11p

Step-by-step explanation:

The merchandise is marked up 11%. This means you pay 100% of the price plus 11%. We can represent that as (1+r) where r is the percent marked above. For 11%, this expression would be 1+0.11. We multiply that by the price p. p(1+0.11). This simplifies to p+0.11p. We can further simplify it to 1.11p.

Answer:

p + 0.11p

i did the test

The correct answer is option a.[tex]\(9 \cdot x + 9 \cdot 3 + 15x\)[/tex].

The correct option is (a).

To use the distributive property to simplify the expression (9(x+3) + 15x), we need to distribute the terms outside the parentheses to each term inside the parentheses.

The given expression is [tex]\(9(x+3) + 15x\)[/tex].

1. Distribute 9 to (x) and (3):

[tex]\[ 9(x+3) = 9 \times x + 9 \times 3 \][/tex]

2. Distribute 15 to (x):

[tex]\[ 15x \][/tex]

So, after using the distributive property, the expression becomes:

[tex]\[ 9 \cdot x + 9 \cdot 3 + 15x \][/tex]

Now, let's compare this with the options:

a. [tex]\(9 \cdot x + 9 \cdot 3 + 15x\)[/tex] - This matches our result.

b. [tex]\(9(x+3+15)x\)[/tex] - This option seems incorrect as it doesn't distribute 9 to each term inside the parentheses correctly.

c. [tex]\(9:x+3+15x\)[/tex] - This option doesn't seem to use the distributive property correctly.

d. [tex]\(9x+9 \cdot 3+9 \cdot 15x\)[/tex] - This option distributes 9 correctly but includes an extra term (9x) that doesn't appear in the original expression.

Therefore, the correct answer is option a.[tex]\(9 \cdot x + 9 \cdot 3 + 15x\)[/tex].

Which expression is equivalent to the given expression after using the distributive property? 9(x+3)+15x

a.9· x+9· 3+15x

b.9(x+3+15)x

c.9: x+3+15x

d.9 x+9· 3+9· 15x

Answer:

24x + 15

Step-by-step explanation:

9(x+3)+15x

Use the distributive property.

9*x +9*3 + 15x

9x + 15 + 15x

Combine the like terms.

Answer:

Length of AC = 48 units.

Step-by-step explanation:

Given in parallelogram ABCD , diagonals AC and B intersects at a point E.

Length of AE = [tex]x^2-16[/tex] units and CE = 6x.

We have to find the length of AC.

According to the property of parallelogram:

Diagonals are intersecting each other at their midpoint.

Since, E is the midpoint AC ;

so, AE = CE

[tex]x^2-16[/tex] =6x

or we can write this as;

[tex]x^2-6x-16[/tex]=0

[tex]x^2-8x+2x-16[/tex]=0

[tex]x(x-8)+2(x-8)[/tex]=0

[tex](x-8)(x+2)[/tex] = 0

Zero product property states that if ab = 0 , then either a=0 or b =0.

By zero product property, we have;

(x-8) = 0 and (x+2) = 0

x = 8 and x = -2

Since, length x cannot be negative so we ignore x = -2.

then;

x = 8

AC = [tex]x^2-16[/tex] = [tex]8^2 -16 = 64- 16 =48[/tex] units.

Therefore, the length of AC = 48 units.

Answer:

length of each plan A work out: 1 hour

length of plan B work out: [tex]\frac{1}{2}[/tex] hours

Step-by-step explanation:

Let x represents the time taken to do plan A

y represents the time taken to do plan B

On Monday there were 5 clients who did Plan A and 2 who did Plan B.

Miguel trained his Monday clients for a total of 6 hours

5x + 2y = 6 -----------> equation 1

On Tuesday there were 3 clients who did Plan A and 8 who did Plan B. .He trained his Tuesday clients for a total of 7 hours

3x + 8y = 7  -------------------> equation 2

Now we solve for  x  and y

Let multiply the first equation by -4 to eliminate y

-20x -8y = -24

  3x + 8y = 7

------------------------ (add both equations)

-17x    = -17

Divide both sides by -17

So x= 1

Plug in 1 for x  in first equation and  solve for y

5x + 2y = 6

5(1) + 2y = 6

5 + 2y =6

Subtract 5 on both sides

2y = 1

y = 1/2

length of each plan A work out: 1 hour

length of plan B work out: [tex]\frac{1}{2}[/tex] hours

Answer:

The length is 25 and the width is 13. (25,13)

Step-by-step explanation:

the formula for perimeter is l+l+w+w=76 or 2l+2w=76

and since we know that the length is 12 more than the width, we can create an equation. w+12=l (-l+w=-12)

solve with elimination method:

2l+2w=76

2(-l+w=-12)

2l+2w=76

-2l+2w=-24

4w=52

w=13

Now that we know w=13, add 12 to the width and you get your width (25)

You can check this with the formula 2l+2w=76

2(25)+2(13)=76

50+26=76

and

w+12=l

13+12=25

Hope this helps!

The dimensions of the field will be 13 ft and 25ft.

The perimeter of a rectangle is given as: = 2l + 2w

Therefore, the perimeter will be:

2(w + 12) + 2w = 76

2w + 24 + 2w = 76

4w = 76 - 24.

4w = 52

w = 52/4.

w = 13

Width = 13 ft

Length will be: = w + 12 = 13 + 12 = 25

Therefore, the dimensions of the field will be 13 ft and 25ft.

Answer:

Expenses for purchasing is $245 ,Revenue $479 and Total profit $ 234

Step-by-step explanation:

Cost of two blouses = 2× 25 = $50

Revenue from blouses = 2× 38 = $76

Profit of blouses = 76- 50 = $26

Similarly cost of 3 skirts = 3×15 = $45

Revenue from Skirts = 3×26 =$78

Profit from skirts = 78-45 =$33

Now cost price of pants = 5×30 =$150

Revenue from Pants = 5×65 =$325

Profit from pants = 325-150 = $175

So Jayla's expenses for purchasing = 50+45+150

                                                           = $245

                                           Revenue = 76+78+325

                                                           = $479

                                        Total Profit = 479 -245

                                                            = $234

Jayla's total expenses were $245, she made $479 in revenue through sales, making her resultant profit $234. This is calculated by subtracting the total expenses from the total revenue.

The subject of this problem deals with the concepts of expenses, revenues, and profit in a small business setting. Jayla spent $50 on the blouses (2 x $25), $45 on the skirts (3 x $15), and $150 on the pants (5 x $30), adding up to a total expense of $245. She sold these items for total revenues of $76 for the blouses (2 x $38), $78 for the skirts (3 x $26), and $325 for the pants (5 x $65), giving her a total revenue of $479. The total profit can be calculated by subtracting the total expenses from the total revenue, and therefore, Jayla made a profit of $234 ($479 - $245).

Let us recall the algebraic formulas which include:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex](a+b)(a-b)=a^2-b^2[/tex]

So if we look closely, we can conclude that the given polynomial observes the third formula of the perfect squares.

Answer:

All the fields will be harvested in 6.25 days

Step-by-step explanation:

because 75 ÷ 12 and 62.5 ÷ 12 is 6.25

You are given the height of the building and the length of the shadow the building gives, so you can set that up as a proportion of Height of building over the length of the shadow so 31/28.

Now you can set the same proportion for Julian, using X for her height, so you would have x/6.

To solve for her height, set the two proportions equal and solve for x:

31/28 = x/6

Cross multiply:

31 * 6 = 28 *x

186 = 28x

Divide both sides by 28:

x = 186 / 28

x = 6.64 feet tall

To find Julian's height using the proportion between the building's height and shadow length and Julian's shadow length, we set up a proportion as follows: 31 feet (building height) / 28 feet (building's shadow) = Julian's height / 6 feet (Julian's shadow). Solving for Julian's height, we determine it is approximately 6.64 feet.

The question pertains to similar triangles and proportionality in shadows cast by objects. Using the concept of similar triangles, we can set up a proportion to find Julian's height. The shadows and the objects (Julian and the building) form two sets of similar triangles because the angles of the sunshine are the same for both objects, and thus their corresponding sides are proportional.

To set up the proportion, we use the building's shadow and height relation and compare it to Julian's shadow and unknown height. So, we write:

Building's height / Building's shadow length = Julian's height / Julian's shadow length
31 feet / 28 feet = Julian's height / 6 feet

To generate an accurate answer, we solve for Julian's height as follows:

Julian's height = (31 feet / 28 feet) \ 6 feet = (31 / 28) \ 6
Julian's height = 6.64 feet (approximately)

This proportional relationship can be used to find unknown heights or lengths of shadows when a reference object is used, provided the angle of light is the same.

Multiplying a complex number by -1 flips it across the origin on the complex plane, changing its direction by 180 degrees but not its magnitude, resulting in a point directly opposite to the initial position.

The question asks about the effect of multiplying a complex number by -1 in the complex plane. Multiplying a complex number by -1 essentially flips the point representing the complex number across the origin. If Point A represents a complex number on the complex plane, multiplying that complex number by -1 will result in a point that lies exactly opposite of Point A with respect to the origin. This operation does not change the magnitude of the complex number but changes its direction by 180 degrees. This is because the complex plane is analogous to a two-dimensional Cartesian coordinate system where complex numbers are represented as vectors. The multiplication by -1 is a reflection across the origin in such a plane.

For example, if a complex number z is represented by the point (a, b) where a is the real part and b is the imaginary part, then multiplying z by -1 gives us the point (-a, -b). This operation is similar to rotating the vector z 180 degrees around the origin or mirroring it across both the x and y axes.

Answer: Our function will be

Distance of the entrance = 180 meters

Speed of Nala who is running towards the entrance of the lair = 9.2

As we know the "Distance-Speed formula":

[tex]Time=\frac{Distance}{Speed}\\\\t=\frac{180}{9.2}\\\\t=19.565\\\\t=19.57\ seconds[/tex]

So, our required function will be

[tex]\sqrt{4}+\sqrt{4}  =4[/tex]

So if the radicand is a perfect square then the solution is rational.
