Answer:

10.1119 m or √102.25 m

Step-by-step explanation:

Using our lovely Pythagorean theorem, a² + b² = c², we can find the value of x in this triangle.

Let's say that a = 4.8 and b = 8.9, then set c as x.

(4.8)² + (8.9)² = x²

23.04 + 79.21 = x²

x² = 102.25

x = √102.25

  = 10.111874208...

  ≈ 10.1119

Answer:

  (a, b, c) = (0, -4, 4)

Step-by-step explanation:

Any of a variety of calculators, spreadsheets, or web sites can solve these equations for you. A calculator result is attached. It shows the solution to be ...

  (a, b, c) = (0, -4, 4)

__

If you'd like to solve the system by hand, here's one way:

Add the three equations together:

  (2a +b +c) +(2b +c +a) +(2c +a +b) = (0) +(-4) +(4)

  4a +4b +4c = 0 . . . . simplify

  a +b +c = 0 . . . . . divide by 4

Substitute this into each of the other equations:

  a +(a +b +c) = 0   ⇒   a +0 = 0   ⇒   a = 0

  b +(a +b +c) = -4   ⇒   b +0 = -4   ⇒   b = -4

  c +(a +b +c) = 4   ⇒   c +0 = 4   ⇒   c = 4

Let's see

Answer:

[tex]\sf length=\dfrac{4n}{m}[/tex]

Step-by-step explanation:

Area of a rectangle = width × length

Given:

Substituting the given expressions into the equation:

[tex]\sf \implies 12mn^2=3m^2n \times length[/tex]

[tex]\sf \implies length=\dfrac{12mn^2}{3m^2n}[/tex]

Factor 12 to 3 · 4:

[tex]\sf \implies length=\dfrac{3 \cdot 4mn^2}{3m^2n}[/tex]

Cancel the common factor of 3:

[tex]\sf \implies length=\dfrac{4mn^2}{m^2n}[/tex]

Simplify [tex]\sf \dfrac{n^2}{n}=n[/tex] :

[tex]\sf \implies length=\dfrac{4mn}{m^2}[/tex]

Simplify [tex]\sf \dfrac{m}{m^2}=\dfrac{1}{m}[/tex] :

[tex]\sf \implies length=\dfrac{4n}{m}[/tex]

Answer:

x = [tex]\frac{3}{a-b}[/tex]

Step-by-step explanation:

Given

ax - bx = 3 ← factor out x from each term on the left side

x(a - b) = 3 ← divide both sides by (a - b)

x = [tex]\frac{3}{a-b}[/tex]

Answer:

 A) 12 cm

 B) 520 cm² (just sides); 720 cm² (sides and base)

Answer:

[tex]\sf{x=\dfrac{7}{2}=3.5 }[/tex]

Step-by-step explanation:

It is necessary to isolate the term of x from both sides in order to solve this problem.

First, subtract by 5 from both sides.

2x+5=12

[tex]\sf{2x+5-5=12-5}[/tex]

Solve.

[tex]\sf{12-5=7}[/tex]

2x=7

Divide by 2 from both sides.

2x/2=7/2

Solve.

Dividing is another option.

7/2=3.5

So, the final answer is 7/2=3.5.

I hope this helps you! Please let me know if my answer is wrong.

Answer:

B, 10.5

Step-by-step explanation:

It's actually 10.54, but since you want be to round it, it's 10.5

The dilations will give the relations:

C'D = (3/4)CD and A'B' = (1/2)AB

And a sketch of the graph can be seen at the end.

First, we want to dilate point C using D as the center of dilation with a scale factor = 3/4.

This only means that we will have the new point C', such that:

C'D = (3/4)*CD

Where CD is the distance between points C and D

b) Similarly, we will dilate the whole segment AB into the segment A'B', such that:

A'B' = (1/2)AB.

It is hard to give the exact graph when we don't know the coordinates of the points, but the graph should look something like the one you can see below.

Answer: cone Cylinder

Surface area is 402ft2 and 69ft2

Step-by-step explanation:

I got the answer right

The appropriate shape to model trunk is cylinder, rest of the tree is cone and surface area of trunk is 25.12 [tex]feet^{2}[/tex]and surface area of rest of the tree is 415.58 [tex]feet^{2}[/tex].

It is the space occupied by a two dimensional surface. The area occupied by a three dimensional object by its outer surface area.

The upper part of the tree is similar to the cone and the trunk is of cylindrical shape. So the appropriate shape used to model the entire is cone above the cylinder.

We have been given the height of entire tree=30 feet,

Width of upper part=10 feet.

Height of trunk=4 feet

Width of tree means diameter of upper part or cone. Height of cone means height of cylinder, width of trunk means diameter of cone.

So, The radius of cone ie 5 feer,radius of cylinder is 1 feet, height of cone be 30-4=26 feet.

Surface area of cone is πrl where l is slant height of cone which is equal to [tex]\sqrt{r^{2} +h^{2} }[/tex]

l=[tex]\sqrt{5^{2} +26^{2} }[/tex]

=[tex]\sqrt{701}[/tex]

=26.47 feet.

Surface area of cone=π*5*26.47

=3.14*5.26*26.47

=415,28 [tex]feet^{2}[/tex]

Surface area of cylinder=2πrh

=2π*4*1

=2*3.14*4

=25.12 [tex]feet^{2}[/tex]

Hence cone and cylinder of surface area 415.28 [tex]feet^{2}[/tex] and 25.12 [tex]feet^{2}[/tex] can be used to model out tree.

The daily expense for food and lodging will be 337.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day.

Assuming the data are normally distributed if the family had a z-score of 1.5.

Then the daily expense for food and lodging will be

z = (x - μ) / σ

1.5 = (x - 247) / 60

90 = x - 247

x = 247 + 90

x = 337

The daily expense for food and lodging will be 337.

Step-by-step explanation:

Given the following question:

Point A = (4, 2) = (x, y)
Slope = 5

Plz mark brainliest ;)

Answer:

Step-by-step explanation:

you can re-write 3 1/2 hours into minutes.

1 hr = 60 minutes,

Therefore:

3 1/2 hours = 3.5 times 60 = 210 minutes

So now we have the ratio:

3 1/2 hours : 36 minutes

210 minutes : 36 minutes

Both numbers can be divided by 6

210/6 = 35 and 36/6 = 6

So now we can re-write the ratio as :

35 : 6
