Answer:

Not factorable

Step-by-step explanation:

We are given a polynomial and are asked to solve or factor it I am assuming.

To solve this, there is a certain rule I like to follow, which is for b (in this case 5), you have to find two numbers that multiply to it, and for c (in this case 13), you have to find two numbers that add to it.

Since no two numbers multiply to 5 and add to 13, therefore this polynomial is not factorable.

Answer:

#1: 146 degrees #2: 111 degrees

Step-by-step explanation:

The angles of a heptagon (a shape with 7 sides) are supposed to add up to 900 degrees, so just add up all the sides that you know and subtract it from 900 and you will have x! Do the same thing with the second one, except is is a hexagon and all the angles should add up to 720 degrees. (Don't forget to add the right angle, which is 90 degrees) So add up all the sides you know and subtract from 720 to get x.

P.S. If correct, please give Brainliest?

Answer:

N = number of sides

The sum of the interior angles of a polygon is equal to (N x 180)-360.

The first problem has 7 sides so the interior angle total = 900 degrees.

Add up all the known interior angles:

96+105+161+123+155+114+x = 900

x = 900-754 = 146 degrees

The second problem has 6 sides so the interior angle total = 720 degrees.

Add up all the known interior angles:

127+40+202+90+150+x = 720

x = 720-609 = 111 degrees

Answer:

x = 32

Step-by-step explanation:

-9 = x - 41

41 + (-9) = x -41 + 41

32 = x

Complete question :

Roger built a model car of a station wagon he actually owns. Based on the ratio on the box, he knows that every inch in the length of his model car represents 25 inches of length in his actual station wagon. The station wagon's car manual shows that the length of the actual car is 193.75 inches.

Complete the following equation so that it can be used to find the length, m, of the model car, then find the length of the model car.

The length of the model car is _ inches

Answer:

7.75 inches

Step-by-step explanation:

Scale factor from the question is :

1 inch : 25 inches

Length of actual car = 193.75

The length of the model car = m

If :

1 = 25

m = 193.75

Using cross multiplication :

25m = 193.75

Divide both sides by 25

25m/25 = 193.75 / 25

m = 7.75 inches

Step-by-step explanation: did it on edge

Answer:

yes

Step-by-step explanation:

For the lengths to form a triangle, the sum of any 2 must be greater than the third, that is

3 + 9 = 12 > 8

3 + 8 = 11 > 9

9 + 8 = 17 > 3

Thus the 3 lengths can form a triangle

Answer:

A

Step-by-step explanation:

Answer:

D. (4,-1)

Step-by-step explanation:

So, we have these two equations:

2x + y = 7

x - 2y = 6

Isolate x in the second equation:

x = 2y + 6

Substitute it into the first equation:

2(2y + 6) + y = 7

4y + 12 + y = 7

5y + 12 = 7

5y = -5

y = -1

Plug y back into the second equation:

x - 2(-1) = 6

x + 2 = 6

x = 4

So, the correct answer is D. (4,-1)

let the height of building be h ft

h/6 = 60/15

h = 6(60/15) = 24

the building is 24 ft high

Step-by-step explanation:

Well first let’s covert the ft to in- 5ft is 60 in and 6ft is 72 in. Then we want to set up 2 fractions based on height and shadow, so we have 60/15=x/72 (we put x because that’s what we’re trying to find). Then we do cross multiplication so now we have 15x=4320. We divide 15, so now we have 4320/15=288. So the building is 288 in tall or 24ft tall! Glad to help! :)

Equality Properties

Step-by-step explanation:

Let's set Huilan's age to h and Thomas's age to t.

Since Huilan is 13 years younger than Thomas, we can write:

The sum of both their ages is 41, so let's combine the variables h and t together.

We said that h = t - 13, so substitute this value into the equation.

Combine like terms.

Add 13 to both sides of the equation.

Divide both sides of the equation by 2.

Thomas's age is 27 years old.

Answer:

divide 15 by 439 you get 25.4

hope you have a wonderful day!

The minimum number of sets of knives Isabella should buy will be 14 sets

Given the least number of knives needed = 439 knives

Amount currently available on ground = 230knives

The remaining amount of knives needed = 439 - 230

The remaining amount of knives needed = 209 knives

If each set on sale contains 15 knives, the number of sets Isabella will need will be:

[tex]Total \ number \ of \ set \ needed = \dfrac{209}{15}\\ Total \ number \ of \ set \ needed = 13.93[/tex]

This shows that the minimum number of sets of knives Isabella should buy will be 14 (approximately)

Sum of all angles of a triangle = 180°

Let the third angle be x.

So, 18.6° + 113.4° + x = 180°

=> 132° + x = 180°

=> x = 180° - 132°

=> x = 48°

So, the third angle is 48°.

Answer: C

Step-by-step explanation:

Option A is true comparisons among the given option as the number are in increasing order A. 4 < √18 < 4.5 .

To determine if this is true, let's calculate the square root of 18:

√18 ≈ 4.2426

Substituting the value into the comparison:

4 < 4.2426 < 4.5

This statement is true because 4 is indeed less than 4.2426, and 4.2426 is less than 4.5. Therefore, Option A is true.

B. 4.5 < √18 < 5

Option B states that 4.5 is less than the square root of 18, and the square root of 18 is less than 5. We have already determined the value of the square root of 18 as approximately 4.2426. Evaluating this comparison:

4.5 < √18 < 5

This statement is also true because 4.5 is not less than 4.2426, and 4.2426 is less than 5. Therefore, Option B is not true.

C. 8.5 < √18 < 9.5

Option C states that 8.5 is less than the square root of 18, and the square root of 18 is less than 9.5. We have already established the value of the square root of 18 as approximately 4.2426. Evaluating this comparison:

8.5 < √18 < 9.5

This statement is false because 8.5 is not less than 4.2426. Therefore, Option C is not true.

D. 17 < √18 < 19

Option D states that 17 is less than the square root of 18, and the square root of 18 is less than 19. Evaluating this comparison:

17 < √18 < 19

This statement is true because 17 is not less than 4.2426, and 4.2426 is less than 19. Therefore, Option D is not true.

In conclusion, among the given options, Option A is true comparisons:

A. 4 < √18 < 4.5

Answer:

96.6feet

Step-by-step explanation:

,

From the attachment, we can see that a triangle is formed.

From trigonometry,

Sin(X)= opposite/hypothesis

Where Opposite sides=25feet

Hypotenuse sides= X feet

Sin(15)= 25/X

Cross multiply

Sin(15)= 0.2588

0.2588=25/X

X= 25/0.2588

X=96.6feet

Hence, the wire is 96.6 feet high

Answer:

115 degrees

Step-by-step explanation:

From what I'm visualizing, D is a point of another isosceles triangle within ABC, so to find the measure of angle BDC, we have to find the other angles first.

First, we have to find angle B and C. since this is an isosceles triangle and AB=AC, these two angles are equal and we find their angle measure by subtracting the known angle A, from the total measure of all angles in a triangle, 180

180 - 50 = 130

then divide that by two to get the two equal angles

130/2 - 65

angle bisector divides the angles in half so the measures of CBD and BCD are 65/2

that leaves the last remaining angle BDC. Again, we take the known angles and subtract them from 180

180 - 65/2 -65/2 = 115

Answer:

8 Pigs.

Step-by-step explanation:

~ P = the number of pig

~ D = the number of ducks

p + d = 10

  4p + 2d = 36

4(10 - d) + 2d = 36

40 - 4d + 2d = 36

40 - 2d = 36

-40       = -40

    -2d = -4

    -2      -2

        d = 2 ducks

p + d = 10

p + 2 = 10

   Therefore, 8 pigs. :)) hope this helped you :))
