The triangles below are similar. Triangle A has a side lengths with the measure 3m,5m, and 4m. Triangle b has side lengths with the measure 12m, 20m, and x
Find the value of x

Answer:

true

Step-by-step explanation:

Thinner candle:

y = length of the candle

x = rate it burns at every minute

y = -1/8x + 30

Thicker candle:

y = length of the candle

x = rate it burns at every minute

y = -1/10x + 30

To find the length after 3 hours:

y = -1/8(180) + 30

y = -1/10(180) + 30

Answer: (2,-2) (-1,1) (-3,-1) (-2,-4)

Step-by-step explanation:

The x-axis is the horizontal line and the y-axis is the vertical line on a graph. The ordered pairs are always in (x,y).

To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

Answer:

(5z-6w)(5z+6w)

Step-by-step explanation:

Hi there!

We're given the expression 25z²-36w² and we want to factor it.

The expression written as a difference of squares. The difference of squares is given as a²-b²=(a-b)(a+b)

Let's label the values of what is a² and b², and then try to determine what a and b are from that information

[tex]a^{2}=25z^2\\b^2=36w^2[/tex]

Alright then! Let's square root both sides to find what a and b are

[tex]\sqrt{a^2}=\sqrt{25z^2[/tex]

Which then means:

a=5z

And then for b:

[tex]\sqrt{b^2}=\sqrt{36w^2}[/tex]

b=6w

Now substitute those values into the formula

a²-b² = (a-b)(a+b)

[tex]25z^{2}-36w^2=(5z-6w)(5z+6w)[/tex]

Hope this helps!

Step-by-step explanation:

Answer:

Step-by-step explanation:

Because x^5 has 5 members. When you group them into 2 members each, there is one x left over. This is most easily seen if you try it with numbers.

The clearest way is to pick something that is not a perfect square to start with.

6 * 6 * 6 * 6 * 6

6^2 is a perfect square. It is grouped into 2 groups. Each one is a 6

So 6^2 = 36. 36 is a perfect square.

You should note that 6 ^3  is not a perfect square. One of the 6s is unmatched and you get a fraction when you square root 6^3.

6 * 6 * 6 = 216. The square root of 216 is 14.697... which goes on forever.

6^4 is a perfect square.

6^4 = 1296 The square root of 1296 is 36.

Answer:

C

Step-by-step explanation:

Using the rule of logarithms

ln[tex]x^{n}[/tex] ⇔ nlnx

Given

2([tex]5^{x}[/tex] ) = 14 ( divide both sides by 2 )

[tex]5^{x}[/tex] = 7 ( take ln of both sides )

xln5 = ln7 ( divide both sides by ln5 )

x = [tex]\frac{ln7}{ln5}[/tex] ≈ 1.21 ( to 2 dec. places ) → C

Answer:

Step-by-step explanation:

here is your solution

First you divide the sides by 2

2(5^x)/2=14/2

5x=7

apply exponent rules

log(5x)=log(7)

Answer:

[tex]35+0.50t=51[/tex]

Step-by-step explanation:

Since the $35 is a one-time fee, 0.50 is the rate, t is the variable, and 51 is the total bill, we can form the equation:

[tex]35+0.50t=51[/tex]

Answer:

0.50t+35=51

Step-by-step explanation:

0.50 is the amount for each text message so it becomes 0.50t (0.50 × text message). This is added to the monthly cost which is 35 dollars (+35) the question wants an equation as the answer so (=51).

The movement of a point along the coordinate geometry is referred to as translation. The  coordinates of the vertices for new quadrilateral are:

[tex]D' = (3,2)[/tex]

[tex]E' = (8,3)[/tex]

[tex]F' = (4,5)[/tex]

[tex]G' = (10,6)[/tex]

Given that:

[tex]D = (1,2)[/tex]

[tex]E =(6,3)[/tex]

[tex]F = (2,5)[/tex]

[tex]G = (8,6)[/tex]

The rule of transformation for 2 units right translation is:

[tex](x,y) \to(x + 2, y)[/tex]

So, we have:

[tex]D' = (1+2,2)[/tex]

[tex]D' = (3,2)[/tex]

Using the above formula, the other coordinates are:

[tex]E' = (8,3)[/tex]

[tex]F' = (4,5)[/tex]

[tex]G' = (10,6)[/tex]

Hence, the coordinates of the vertices for new quadrilateral are:

[tex]D' = (3,2)[/tex]

[tex]E' = (8,3)[/tex]

[tex]F' = (4,5)[/tex]

[tex]G' = (10,6)[/tex]

Answer:

3 books on each shelf

5 books on each shelf

Step-by-step explanation:

Answer:

29 stories - 49 stories = number of stories they need to go

28 - 49 = 21

the answer is 21

they have 21 more stories to go

The number of stories they still need to go is 19 stories.

It is given that building is 48 stories high and when the emergency happens they have already gone to 29 stories.

We have to calculate the number of stories they still need to go.

What will be the value, if we subtract 2 from 4 ?

The value after subtracting will be 4 - 2 = 2.

As per the question ,

The total number of stories in building = 48

When emergency happens they have already gone 29 stories.

So ,

The number of stories they still need to go after the emergency happens can be calculated as ;

48-29 = 19

Thus , they still need to go 19 stories.
