Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary

Answer:

The scale factor is 2.5

Step-by-step explanation:

took k-12 test

When a shape is dilated, the size of the shape changes

The true statement is (d) The scale factor is 2.5.

Dilation involves changing the size of a shape or figure

In figure A, we have:

Length = 0.6

In figure B, we have:

Length =1.5

The scale factor is then calculated as:

[tex]k = \frac{1.5}{0.6}[/tex]

Divide

[tex]k = 2.5[/tex]

Hence, the true statement is (d) The scale factor is 2.5.

Answer:

Rearrange: y=-2x+3

if x=6 then y = -9

if y=-1 then x = 2

Step-by-step explanation:

Algebra

to rearrange here are the steps

26x+13y=39

First move x to other side by subtraction

13y= -26x+39

to get y as just y divide everything by 13. Since 13/13=1 or 13y/13= y

y=-2x+3

Answer:

(13+x)cm

Step-by-step explanation:

Given data

Length of sides

1cm, 5cm, 7cm

Since the shape is four-sided and the fourth side is not given, let the fourth side be x

so

The perimeter of the polygon is

P= 1+5+7+x

P= 13+x

Hence the perimeter of the polygon is

P= (13+x)cm

Answer:

1500

Step-by-step explanation:

Total cost would be 60%+40%

Since we have 60% amount already

0.60* total cost=900

total cost=90000/60

=1500

It depends on the context. No number besides 0 is given, so it can't really be the other ones with numbers.

Answer:

x=-4     y=-7

Step-by-step explanation:

-4x+y=9     get y alone

add 4x both sides

y=4x+9

insert into y=2x+1

2x+1=4x+9

subtract 1 both sides

2x=4x+8

subtract 4x both sides

-2x=8

divide by -2

x=-4

y=2x+1

y=2(-4)+1

y=-8+1

y=-7

check

-4(-4)+(-7)=9

-16+(-7)=9

9=9

x=-4

y=-7

Answer:

[tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]

Step-by-step explanation:

Skills required: Ordering a set of numbers

1) [tex]-8,-19,0,\frac{1}{4}, \frac{1}{2}[/tex] are the numbers we are given. There are 2 important things to think about when ordering this set.

2) Based on this, we can split the 5 numbers into 3 groups:

3) Starting with the negative group, we can easily find which number is greater.

-1 is greater than -2.

-23 is greater than -35.

Based on this: -8 is greater than -19. That means when ordering our numbers, -8 is the first number, and -19 is the second number

4) 0 is the 3rd number, since it is less than positive numbers and greater than negative numbers

5) Now onto the positive numbers, which is also easily solvable.

When you have two fractions, there are different ways to find out which fraction is greater than the other. I will show you 2 different ways here.

This means that [tex]\frac{1}{4}[/tex] is the 4th number, and [tex]\frac{1}{2}[/tex] is the 5th term.

Our ordered pair would then be: [tex]-19,-8,0,\frac{1}{4}, \frac{1}{2}[/tex]

Answer:

Option B

Step-by-step explanation:

Option A, C and D have x- values that repeat and you cannot have that.

Y values can repeat but not x-values.

Option B has all x values with different y-values

Answer:

B.

Step-by-step explanation:

an output can have more than one input but an input can only have one output

basically only one arrow can go from the input to the output and b is the only one who's graph thing is like that

Given:

The point is B(2,5) and its image is B'(1,2.5).

To find:

The scale factor.

Solution:

If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as

[tex]k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}[/tex]

x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is

[tex]k=\dfrac{1}{2}[/tex]

Therefore, the scale factor is  [tex]\dfrac{1}{2}[/tex] and the correct option is D.
