4.A trapezoid with a perimeter of 30 units is
graphed on a coordinate grid. The trapezoid is
dilated by a scale factor of 0.3 with the origin as the
center of dilation. If (x,y) represents the location of
any point on the original trapezoid, which ordered
pair represents the coordinates of the corresponding
point on the resulting trapezoid?
A. (30x, 30y)
B. (X - 0.3, y +0.3)
C. (0.3x, 0.3y)
D. (x + 0.3, y +0.3)

Answers

Answer:

It would be (x0.3,y0.3). C is the answer

Step-by-step explanation:

Because if you actually read it, it already gave you the answer which is the scale factor of 0.3

so that would lead to (x0.3,y0.3)

Ava says that 100
12 is equivalent to 2 (52 – 6). Is this true or false?
O True
False

Answers

Answer:

False

Step-by-step explanation:

Assuming that the first equation is 10x - 12, you need to solve both equations in order to see if the equations are equivalent from each other.

[tex]10x-12[/tex]

[tex]10x-12=2(5x-6)[/tex]

[tex]=2(5x-6)[/tex]

Then...

[tex]2\times(52-6)[/tex]

Use Order of Operations...

[tex]52-6=46[/tex]

[tex]2\times46=92[/tex]

[tex]2(5x-6)<96[/tex]

Therefore "false" or the second option is your answer.

Hope this helps.

what is the x intercept of the line represented by the equation below 3x+6y=30​

Answers

Answer:

(10,0)

Step-by-step explanation:

3x+6y=30

3x+6(0)=30

3x=30

x=10

Answer:

hmmm? well I guess I can solve for x in relation to y and vice versa

but to actually solve for x and y you will need another equation of x and y

3x=30+6y

x=10+2y=2y+10

-6y=30-3x

-2y=10-x

2y=-10+x=x-10

y=(1/2)x-5

well, y=(1/2)x-5 is a line with slope 1/2 and y-intercept (0,b) of

A zoo has the ratio to zebras (1 giraffe for every 4 zebras) What percent of this grouping of animals are giraffes? What percent of this grouping are zebras?

Answers

Answer:

20% of the animals are giraffes

80% of the animals are zebras

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

Explanation:

Let's say there are 5 animals. This would mean there's 1 giraffe and 4 zebras, since we have four zebras per giraffe.

The percentage of giraffes is 1/5 = 0.20 = 20%

and the percentage of zebras is 4/5 = 0.80 = 80%

The requried percentage of giraffes is 20% and the percentage of Zebras is 80%.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

What are percentages?

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

A zoo has the ratio to zebras (1 giraffe for every 4 zebras)
The total proportion of the zebras and giraffes = 5,
Percentage of giraffe = 1 / 5 × 100% = 20%
Percentage of zebras = 4 / 5 × 100% = 80%

Thus, the requried percentage of giraffes is 20% and the percentage of Zebras is 80%.
