1. 1300/65=20 sales

2.2+2=4

22-4=18

18/2=9

unknown number of inch=x+3

x=9

(9)+3=11

unknown number is 11 inch.

Answer:

  x = 12

Step-by-step explanation:

The sum of the exterior angles of a convex polygon is 360°.

  (5x +4)° +(4x +9)° +(9x -6)° +(4x +1)° +(7x +4)° = 360°

  29x +12 = 360 . . . . . divide by °, collect terms

  29x = 348 . . . . . . . subtract 12

  x = 12 . . . . . . . . . divide by 29

Answer:

x=11.58

Step-by-step explanation:

The sum of an exterior angle of a polygon is 360°,

9x-6+4x+9+5x+4+7x+4+4x+1=360°

29x+24=360

29x=360-24

29x=336

x=336/29

x= 11.586

x=11.58

Hope it helps! :)

Step-by-step explanation:

Sum of the interior angles of a Pentagon = 540

Therefore, 100+x+(3x+30)+(2x-10)+80=540

100+x+3x+30+2x-10+80=540

Group like terms

x+3x+2x=540-100-30+10-80

6x=340

6x=340

x=56.6

Answer:

The answer is y + 5 = 0

Step-by-step explanation:

We know that, the equation of a line passing through point P(a, b) and slope m is given by

(y – b) = m(x – a) ...(1)

Here, The given point is P(3, -5) and slope is m = 0

from (1) we get

[(y – (-5)] = 0(x – 3)

y + 5 = 0 is the required equation of line.

Thus, The answer is y + 5 = 0

Answer:

144 in²

Step-by-step explanation:

Area of square: [tex]s^2[/tex]

Here s is 12 inches.

Using the formula:

area:  [tex]s^2[/tex]

area: 12²

area: 12 * 12

→ 144 in²

The formula to find area of square is:

[tex] \tt \: area = {s}^{2} [/tex]

Answer:

They are not similar

Step-by-step explanation:

To see whether the triangles are similar or not we can compare their side lengths:

AB = 24

AX = 6

AX/AB = 1/4 is the ratio now let's compare this to AY/AC

AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.

Answer:

(x + 9)(x - 9)

Step-by-step explanation:

Apply the Difference of Two Squares formula: x² - y² = (x + y)(x - y)

Rewrite 81 at 9²

⇒ x² - 81 = x² - 9² = (x + 9)(x - 9)

Answer:

[tex]\left(x+9\right)\left(x-9\right)[/tex]

Step-by-step explanation:

[tex]x^2 - 81[/tex]

factor 81 as 9²

[tex]x^2-9^2[/tex]

using formula: a² -b² = (a+b)(a-b)

[tex]\left(x+9\right)\left(x-9\right)[/tex]

Answer:

29

Step-by-step explanation:

We can make an equation from the word problem:
H +T =87
2T+T=87

3T=87

87÷3=29

T=29
This is our answer but we can substitute this into our equation:
H +T = 87

2T+T =87
2(29)+29 = 87

58+29=87

87=87
So 29 is ✅

Countries with the highest populations in the world also have the highest population densities is False.

The number of people living in a country is known as population.

The number of people living in a unit area is called population density. It is the ratio of the population of the country and the area of the country.

Countries with the highest populations in the world also have the highest population densities.

This statement is false because the population density depends on the area.

For example - China is having the first rank in population but its population density is 153 persons per kilometer square is much lesser than India which has a population density is 403 persons per kilometer square.

More about the population link is given below.

Answer:

Step-by-step explanation:

I took the test

I'm going to try the strategy of "narrow it down slowly."

Let's start with how many perfect squares there are less than 1000. We have

0^2 = 0

1^2 = 1

2^2 = 4

3^2 = 9

...

30^2 = 900

31^2 = 961

32^2 = 1024

This means there are 0...31 so 32 perfect squares less than 1000.

Three times an odd integer... this is tricky. If you think about it, if n is divisible by three, then n must have a factor of 9 in it (why?), so [tex]\sqrt n[/tex] must have a factor of three! Boom, now we just have to count how many odd numbers from 0...31 are divisible by three. The first one is 1(3), the second is 3(3), the third is 5(3), the fourth is 7(3), and the fifth is 9(3). This means there are five such numbers.

Applying the altitude theorem and solving algebraically, the length of DC is: 6.

If an altitude of a right triangle divides an opposite side into a and b, based on the altitude theorem, the height (h) of the altitude = √(ab).

Solving algebraically:

Let DC = x

Therefore:

BC = 4x

Applying the altitude theorem, we would have:

12 = √(4x × x)

12 = √(4x²)

12 = 2x

12/2 = x

6 = x

x = 6

Therefore, DC = x = 6.

Step-by-step explanation:

Answer:

5/7 = 25/35

Step-by-step explanation:

First look at the numerators of the fractions. One fraction has both a numerator and denominator. Find the number that this numerator is multiplied by to get to the numerator that is missing its denominator. Multiply the known denominator by this number to find the unknown denominator.

Basically, what number did we multiply to get 25? its 5 (5x5=25)

So, multiply 7 by 5 and you'll get 35

Answer:

B. $3

Step-by-step explanation:

A single 6-pound package is approximately $5 shipping fee.

A 2-pound package is approximately $3.50 shipping fee.

A 4-pound package is approximately $4.50 shipping fee.

The question stated, "What is the approximate difference (this means we are most likely subtracting) in cost of shipping a 2-pound and a 4 pound package(the and means we are adding both 4-pound and 2-pound together) opposed to a single 6-pound package?"

As calculated above, we should add the 2-pound package and the 4-pound package together.

3.5 + 4.5 = 8

One single 6-pound package is $5, so we need to subtract the 8 with the 5.

8 - 5 = 3

Answer:

$0.80

Step-by-step explanation:

Let y be the number of cakes that can be bought then...

xy=4

y(2x+1)=13

Distribute the y to each term in the parentheses...

y(2x)+y(1)=13

2xy+y=13

xy=4

Multiply the second equation by 2...

2xy+y=13

2xy=8

Solve the equation using elimination (subtract the two equations and eliminate 2xy)...

y=13-8=5

Now, plug 5 back in for y to solve for x...

xy=4

5x=4

Divide both sides by 5

x=$0.80

Answer:

vertex = (6, -9)

point = (0, 27)

see attached diagram for graph

Step-by-step explanation:

[tex]f(x)=x^2-12x+27[/tex]

Vertex form:  [tex]y=a(x-h)^2+k[/tex]

where (h, k) is the vertex

Rewrite function in vertex form:

[tex]\implies f(x)=(x-6)^2-36+27[/tex]

[tex]\implies f(x)=(x-6)^2-9[/tex]

Therefore, vertex = (6, -9)

As the coefficient of [tex]x^2[/tex] is positive, the parabola will open upwards (u shaped).

Point to plot:  

f(0) = 27

Therefore, point = (0, 27)
