If triangle DEF is dilated by a scale factor of 1/2 with center of dilation at the origin
(0,0), what is the x-coordinate of E'?
Please help 20 points

Answer:

Here's how to solve the problem

Step-by-step explanation:

50% of participants are in 6th grade.

100% - 50% = 50

0.3, when converted to percentage form is 30%

50% - 30% = 20%

This remaining 20% is how many participants, out of the whole, are in the 7th grade

20% = 0.2 = 2/10 = 20/100

Answer:

50 - 8 - 30 + 28 =

(50 + 28) - (8 + 30) =

78 - 38 =

40

Its much easier to solve 78 - 38 than 50 - 8 - 30 + 28, which is why you simplify the question before calkylating it.

Answer:

64.428

Step-by-step explanation:

well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence

so if we add all of the numbers up it will give us

451

then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with

around 65 or exactly it would be

Answer:

15

Step-by-step explanation:

the square root of 225 is 15 there are steps

Answer:

√225=√15²=±15 is your answer

The set {126, 168, 189} has  21 as a common factor.

The set{154, 231} has  11 as a common factor.

If a number m is completely divisible by number n. Then number n will be the one factor of number m.

(a). Given set of number is, {126, 168, 189}

Now check,  21 is a common factor or not.

 [tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]

It is observed that all numbers are completely divisible by 21.

So that , 21 is common factor.

(b). Given set of number is, {154, 231}

      [tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]

It is observed that all numbers are completely divisible by 11.

Step-by-step explanation:

Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship

Solution:

Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:

y = x + 15

You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.

Rodrigo:     10         20            30

Isabella:      25        35           45

When x = 10:   y = x + 15 = 10 + 15 = 25

When x = 20:   y = x + 15 = 20 + 15 = 35

When x = 30:   y = x + 15 = 30 + 15 = 45

Given:

The ratios are  [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].

To find:

Whether the ratios form a proportion or not.

Solution:

If two ratios represent the same relationship then they form a proportion.

We have,

[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]

Write the given ratios in the simplified forms.

[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]

[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]

And,

[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]

[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]

Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.

Answer:

1.5

Step-by-step explanation:

-1.2(3-×)=-1.8

-3.6+1.2×=-1.8

1.2×=3.6-1.8

1.2×=1.8

1.2/1.2×=1.8/1.2

×=1.5

Length of Simon's tent = 6 feet

Distance from the bottom of the tent to the tent's base = 8 feet

Let the length of rope be R.

The tent and the rope forms a right angle triangle where the rope is the hypotenuse.

We know that :

[tex]\color{hotpink} \tt{hypotenuse}^{2} \color{plum}= {base}^{2} + {height}^{2} [/tex]

Which means :

[tex] = \tt {R}^{2} = {6}^{2} + {8}^{2} [/tex]

[tex] =\tt {R}^{2} = 36 + 64[/tex]

[tex] = \tt {R}^{2} = 100[/tex]

[tex] =\tt R = \sqrt{100} [/tex]

[tex]\hookrightarrow\color{plum}\tt \bold{R = 10 \: feet}[/tex]

Thus, the hypotenuse of this triangle = 10 feet

▪︎Therefore, the length of the rope = 10 feet

Answer:

(B) f(-4)=g(-4) and  f(0)=g(0)

Step-by-step explanation:

From the given graph, the lines f(x) and g(x) intersects at two different points.

When x=-4, f(-4)=4 and g(-4)=4

When x=0, f(0)=4 and g(0)=4

Therefore, the points which represent where f(x)=g(x) are:

f(-4)=g(-4); and

f(0)=g(0)

The correct option is B.
