Triangle A is the pre-image, and triangle B is the image. Find the scale factor for this dilation if the center of dilation is at (0,0)

Answer:

ab+ac

Step-by-step explanation:

The area of the figure is the length multiplied by the width, which is (a+b)c. By the commutative property, this is equal to c(a+b), and by the distributive property, it is also equal to ac+bc. It is not equal to ab+ac.

Answer:

c(a+b)

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation: golf balls are lighter than bowling balls.

Answer:

first answer is correct answer

Answer:

10

Step-by-step explanation:

the two triangles formed from c are similar which means the sides are proportional

the proportion of one length of a side of a triangle to a similar side of the other triangle is the same as another side to its corresponding side of the other triangle. god im bad explaining stuff

anyway 2 is to 8 what 2.5 is to length BC. 2/8 = 2.5/x

    -crossmultiplyyy

2*x = 2.5*8

2x = 20

2x/2 = 20/2

x = 10

Answer:

10x3=30 6x12x19=1368 1368+30=1398

Answer:

D

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] ab sinC ( a, b are the sides and C the angle between them ) , then

A = [tex]\frac{1}{2}[/tex] × 5 × 3 × sin40° = 7.5 × sin40° ≈ 4.8 units² ( to nearest tenth )

Answer:

8(2x + 5y)

Step-by-step explanation:

You cant fact (take out) 8 from both 16 and 40 since 8 is a factor for both.

Step-by-step explanation:

=16x+40y

=8(2x+5y)

answer is 4

Answer:

3, 5

Step-by-step explanation:

Looking at the graph, the x-intercepts are -5, -3, 1 and 5.

Hence the graph equation is (x+5)(x+3)(x-1)(x-5)

Answer:

  90

Step-by-step explanation:

The number that goes in the blank is x, where ...

  0.30x = 27

Dividing by 0.30, we find ...

  x = 27/0.30 = 90

Then ...

  30% of 90 = 27

Answer:

644

Step-by-step explanation:

SA=[2×(5×20 + 5×6 + 20×6)] +

[2×(4×12 + 4×6 + 12×6)] -

[ 2× 12×6]

= [2×(250)]+[2×(144)] - [144]

= 500+288-144

= 644 cm²

Answer:

-0.8 is the correct answer of this question

Answer:

-16/45

Step-by-step explanation:

When you mulitply these two fractions together it's best to muliteply them by the number across so therefore 8x-2= -16 and 15x3= 45 which you end up with -16/45

Answer:

4 5/6

Step-by-step explanation:

4 5/6 = 29/6

5 1/6 = 31/6

29/6 + 31/6 = 60/6 = 10

Answer:

2167.7 sq yds

Step-by-step explanation:

SA(cone) = πr² + πrs     ('s' = slant height)

= π(15)² + π(15)(31)

= 225π + 465π

= 690π

= 2167.7

Answer:

Yes

Step-by-step explanation:

Given expression: 3x+9

Take 3 outside from the expression, we get,

= 3(x+3), which is called the equivalent expression

Answer:

No

Step-by-step

We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.

Answer:

Y=x+3

Step-by-step explanation:

Just subtract the x value from the y value and you will always get the right answer... But isn't this iready? A test?

Answer:

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

⇒ Measurement of the arc VU= 80°.

Answer:

80 is the correct answer

Awnser :

Ten

Explanation :

In a relaxed practice setting with no pressure, the average player should be able to make at least ten in a row. But free throws typically come in pressure situations, so managing the pressure is as important as practicing form.

Answer:

4.87805%

Step-by-step explanation:

yuh yw

Answer:

= 4.87805% difference

Solution:

Calculate percentage difference

between V1 = 239900 and V2 = 251895

|V1−V2|[(V1+V2)2]×100=?

=|239900−251895|[(239900+251895)2]×100

=|−11995|[4917952]×100

=11995245897.5×100

=0.0487805×100

=4.87805%difference

Answer:

A, E

Step-by-step explanation:

The mean of the pizza truck:

(400 + 800 + 1000 + 1000)/4 = 800

The mean of the burger truck:

(800 + 700 + 900 + 800)/4 = 800

A is correct, which voids answer C

The median of the pizza truck:

400, 800, 1000, 1000

              \     /

               900

The median of the burger truck

700, 800, 800, 900

            800

900>800 so E is correct, voiding all other answers
