The Scale Factor From The Large Triangle To The Small Triangle Is 3:1 What Is The Length Of Side X Of

Answers

Answer 1

Answer:

10 i guess

cause

8*3=24

3*10=30

Answer 2

Step-by-step explanation:

Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)

Therefore 3x = 30 and x = 10.

z = 106

Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.

Answers

Answer: x = 8/4 = 2

12(2) + 4(6) = 24 + 24 = 48 = 6*8

Step-by-step explanation:

$12X + $6(4) = (X+4)*$8

12X + 24 = 8(x+4)

12x + 24 = 8x + 32

12x + 24 - 8x - 32 = 0

4x - 8 = 0

4x = 8

x = 8/4 = 2

Last night, the temperature fell from 0°F to -13 in 4 § hours. What was the average temperature change per hour? Solve the division problem. 2 1 -13= - 4 5 5 The temperature drop per hour can be represented by I °F. QUICKLY​

Answers

Answer:

3.25 degrees/hour

Step-by-step explanation:

Last night, the temperature fell from 0°F to -13°F in 4 hour.

We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.

Change in temperature = -13°F -0°F = -13°F

So,

[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]

So, the change in temperature is 3.25 degrees/hour.

Answer:

-3.25 degrees an hour

Step-by-step explanation:

-13 ÷ 4 = -3.25

Answer:

Step-by-step explanation:

you just need to add both equations

you will get 3y=12+6=18

3y=18

y=6

now replace y=6

3x+12=6

3x=6-12

3x=-6

x=-2

(-2,6)

Answer:

(-2,6)

Step-by-step explanation:

3x + 2y = 6

-3x + y = 12

3x + -3x = 0

2y + y = 3y

6 + 12 = 18

3y = 18

3y/3 = 18/3

y = 6

-3x + y = 12

-3x + 6 = 12

-3x = 12 - 6

-3x = 6

-3x/-3 = 6/-3

x = -2

Pls help Im bad at math no matter how much I try Select the correct answer.Read the following editorial letter.Dear Citizens of Triston,As a concerned citizen of Triston and a member of the North Carolina Conservation of Nature Council, I am asking for the community'shelp with a serious issue. First, I want to congratulate our town's mayor and city council for planning to build a new community theater.However, do they realize that building the theater on Asbury Woodlands will destroy the prime breeding ground for an endangeredspecies?The Bachman's warbler is a small, green-and-yellow bird about four inches in length. Since 1897, the population of the Bachman'swarbler in North Carolina has decreased from more than 500,000 to fewer than 100. The main reason is the destruction of the areas (likeAsbury Woodlands) that the bird uses for its natural breeding grounds. Bachman's warblers prefer thickly wooded swamps and wetthickets in full-grown forests. It's there that they build their nests and feed on insects.This fact does not mean that we cannot build a community theater. We simply must consider building it in a slightly different location.After all, our community has forever prided itself on caring for our natural surroundings. The city council's honorable concern for theendangered Bachman's warbler would smooth the ruffled feathers of many voters. With the council's help and the support of ourtownspeople, future generations will appreciate the beauty of this little bird.Sincerely,Redmond HarrisWhich statement best captures the main argument of the letter?
