Answer:

P = 69!

Step-by-step explanation:

23+17+29 = 69 :)

Answer:

P = 69

Step-by-step explanation:

P = A + B + C

A = 23

B = 17

C = 29

P = 23 + 17 + 29

P = 69

Answer:

The rate of change is 25 and that means the cost per day is $25

Step-by-step explanation:

Since we have a constant rate of change, we can select any two points, apply the slope formula

The slope formula is;

m = (y2-y1)/(x2-x1)

(x1,y1) = (3,75)

(x2,y2) = (6,150)

m = (150-75)/(6-3) = 75/3 = 25

What the rate of change means here is that the cost per day is $25

Answer:

Dialated by a scale factor of two, reflected across the x axis, and transformed three units left

Step-by-step explanation:

The triangle was dilated by a scale factor of 2

What is similarity transformation?

One or more stiff transformations (such as reflection, rotation, and translation) followed by a dilation make up a similarity transformation. An image that resembles the original figure is produced when a figure undergoes a similarity transformation.

The following steps are followed while determining the similarities:

Solution:

Given:

AB=2, AC=1, BC=√5

DC=4, DF=2, EF=2√5

So scale factor is 4/2 = 2/1 = 2√5/√5 = 2

hence we get tha scale factor as 2.

Therefore, In the similarity transformation of abc to def, abc was dilated by a scale of 2.

Answer:

13 and 32

Step-by-step explanation:

let one number be x

Then the other number is x + 19 , then

x + x + 19 = 45

2x + 19 = 45 ( subtract 19 from both sides )

2x = 26 ( divide both sides by 2 )

x = 13

The 2 numbers are 13 and 13 + 19 = 32

Answer:

40

Step-by-step explanation:

Percentage Calculator: 126 is what percent of 315? = 40.

Answer:

40 %

Step-by-step explanation:

To get the percent you do:

126 divided by 315

= .4

Answer:

huh i dont understand

Step-by-step explanation:

Answer:

it answer would be 50% coz we take out percentage from 100.

Step-by-step explanation:

first add 17% and 33% it would be 50%

then subtract 50%from 100%

answer would be 50%

Answer:

No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.

Step-by-step explanation:

Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).

- we can use 7 and 10 interchangeably.

Fill in the equation, [tex]a^2 + b^2 = c^2[/tex]

                 where c = 12, and a or b = 7 or 10.

To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.

Therefore, [tex]7^2 + b^2 = 12^2[/tex] or [tex]10^2 + b^2 = 12^2[/tex]

[tex]7^2 + b^2 = 12^2[/tex] ==> 49 + b^2 = 144 ==> b= [tex]\sqrt{95[/tex] ==> 9.746

b= 9.7, not 10.

[tex]10^2 + b^2 = 12^2[/tex] ==> 100 + b^2 = 144 ==> b = [tex]\sqrt{44[/tex] ==> 6.633

b= 6.6, not 7.

Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.

Answer: well 2/3 of 1650 is 1100 so 1650-1100=550, so the cooper family spend $1100 and the reynolds family spent $550

Step-by-step explanation: i think that’s right

Answer:

No

Step-by-step explanation:

Given :-

And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.

Pythagoras Theorem :-

Here the two smallest sides are 4 & 6 .

Sum of Squares of 4 and 6 :-

[tex]:\implies[/tex] 4² + 6²

[tex]:\implies[/tex] 24 + 36

[tex]:\implies[/tex] 60

Square of 7 :-

[tex]:\implies[/tex] 7²

[tex]:\implies[/tex] 49

And :-

Hence the triangle is not a right angle triangle.

Answer:

No, this triangle is not a right triangle.

Step-by-step explanation:

Step 1: Definition(s)/explanations

Formula:

[tex]pt-a^2+b^2=c^2[/tex]

[tex]legs=a,b[/tex]

[tex]hypotenuse=c[/tex]

Step 2: Solve.

Now, I just plug the numbers into the formula.

[tex]a^2+b^2=c^2[/tex]

[tex]4^2+6^2=7^2[/tex]

[tex]16+36\neq 49[/tex]

If the legs of the triangle do not equal the hypotenuse, then the triangle cannot be a right triangle.

Step 3: Conclude.

Therefore, the triangle cannot be a right triangle.

Answer:

this is your ans.. i hope it is helpfull

Answer:

Your answer is B

Step-by-step explanation:

The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.

Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.

Sorry if this is confusing the book will have better explanations than I can give.

Answer:

So option 4; [tex]\frac{35}{100}[/tex] is the correct option

Step-by-step explanation:

First, we need to convert [tex]\frac{2}{10}[/tex] so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10

[tex]\frac{2}{10} *\frac{10}{10} = \frac{20}{100}[/tex]

Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.

[tex]\frac{45}{100} + \frac{20}{100} = \frac{65}{100}[/tex]

Now that we have the total distance walked, we need to subtract that to 1 mile. [tex]1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}[/tex]

[tex]\frac{100}{100} -\frac{65}{100} = \frac{35}{100}[/tex]

So option 4; [tex]\frac{35}{100}[/tex] is the correct option

the tent can be :

1. perimeter 120 m.

40 sides polygon with 3 metres length each.

so, x = 360/40 = 9°

2. perimeter 135 m.

45 sides polygon with 3 metres length each.

so, x = 360/45= 8°
