Whats The Scale Factor ?

Answers

Answer 1
Answer: Choice C) 2

=======================================================

Explanation:

The vertical side of the blue triangle is PR = 2

The corresponding vertical side of the green triangle is P'R' = 4

The scale factor is the ratio of those two corresponding sides. So we divide the two side lengths.

scale factor = (P'R')/(PR) = (4)/(2) = 2

---------------------

We could also say:

scale factor = (R'Q')/(RQ) = (6)/(3) = 2

Or you could find the lengths of PQ and P'Q' through the distance formula, or Pythagorean theorem, and apply the same idea as shown above.

I hope this helps:

Answer:

16 1/15

Step-by-step explanation:

Add the whole numbers.  7+8=15

Now, combine the fractions 2/3 and 2/5. To do so, you need a common denominator. The LCD between 3 and 5 is 15.

Whatever you do to one side you must do to the other.

(5/5) 2/3+ 2/5 (3/3)

10/15+6/15=16/15

15+16/15

16/15 is an improper fraction, so convert this fraction to a mixed number.

16/15= 1 1/15

Finally, add the two together. 15+ 1 1/15=

Solve for x in the triangle below. Show your work!
2
84

Y
N

Answers

Answer:

x = 48°

Step-by-step explanation:

In the given triangle XYZ,

Sides XY and XZ are congruent.

Therefore, both the sides will be equal in measure.

By the definition of isosceles triangle,

"Opposite angles of the equal sides are equal in measure"

m∠Y = m∠Z = x°

m∠X = 84° [Given]

By the triangle sum theorem,

m∠X + m∠Y + m∠Z = 180°

84° + x° + x° = 180°

2x = 180 - 84

x = 48°

Therefore, measure of x = 48° will be the answer.

Answers

Answer:

Only one triangle is possible.

Step-by-step explanation:

Triangle inequality says that if sum of any two sides of the traingle is greater than the third side, then the triangle is possible.

Here,

,

Therefore, a triangle is possible with the given measurements,

Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,

By SSS congruency criteria both the triangles will be congruent.

Thus, all triangles with same measurement will be congruent to each other.

Hence, only one triangle is possible.

find the highest common factor of 14(3x+1)^ and 7(3x+1)​

Answers

Answer:

The highest common factor is 7(3x+1)

Step-by-step explanation:

Here, we want to find the highest common factor of both expressions

As we can see, the highest common factor of 7 and 14 is 7

Now, we have the second expression which is (3x+1)

No matter what the first expression is raised to, it still stands that the highest common factor we shall have there is 3x+ 1 as concerns the term

inside the bracket

Thus, the highest common factor of both terms is 7(3x + 2)

-1957.2

1957.2

-978.6

978.6

Answers

Answer:

- 978.6 gallons per hour

Step-by-step explanation:

Given that :

Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal

Time during which change occurred : 2:00 pm to 4:00 pm

Average change per hour : [Change in gallon of gasoline / time interval (hour)]

Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons

Time interval = 4:00 pm - 2:00 pm = 2 hours

Hence, Average change per hour :

-1957.2 / 2

= - 978.6 gallons per hour

Solve for x in the following figure.

Answers

Answer:

x = 80

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

First, find the angle J:

60+40 = 100, J = 80 because 100+80= 180 degrees.

Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.

x + 20 = 100

x = 80 degrees.
