Answer:

2rootover5

Step-by-step explanation:

just use pythagoraus theorem

Answer:

x ≈ 4.5

Step-by-step explanation:

First, use the Pythagorean theorem to find the missing variable with side 8 and hypotenuse 10.

a² + b² = c²

a² + 8² = 10²

Square the variables

a² + 64 = 100

Subtract 64 from both sides.

a² = 36

Take the square root of both sides.

a = 6.

Now we can find the other triangle and we now know that one side is 4 and the hypotenuse is 6.

a² + b² = c²

x² + 4² = 6²

Square the variables.

x² + 16 = 36

Subtract 16 from both sides.

x² = 20

Square root. (refresh if you don't see this part.)

[tex]x=\sqrt{20}\\\text{Factor out a 2.}\\x=2\sqrt{5}[/tex]

Converted to decimal to the nearest tenth, the answer is

x = 4.5.

Now let's prove it.

[tex]a^2+b^2=c^2\\\text{Substitute variables.}\\(2\sqrt{5})^2+4^2=6^2\\\text{Factor the 2 in.}\\(\sqrt{20})^2+4^2=6^2\\\text{Square the variables.}\\20+16=36\\\text{Add.}\\36=36[/tex]

Answer:

Solution given:

The length of the garden[l] = 24 3/4 =99/4feet.

breadth or width [b]=b

perimeter of his garden = 70 1/2=141/2 feet.

2[l+b]=141/2ft

99/4+b=141/4

b=141/4-99/4

b=21/2

b=10 ½ft

So the width of the garden is 10 ½ft.

Answer:

x = 10.8

Step-by-step explanation:

Cos∅ = adj/hyp

Cos26 = x/12

Multiply both sides by 12

12 * cos26 = x

Use calculator

10.785528555590004 = x

Round

x = 10.8

Answer: [tex]c+3m[/tex]

Step-by-step explanation:

Given

A telephone call costs c cents for first 3 minutes and m cents for each additional minute.

Any call beyond 3 minutes costs

[tex]\Rightarrow c+mt[/tex]

where t is the minutes spent beyond 3 minutes

For 6 minutes , t is 3

thus, it can be written

[tex]\Rightarrow c+3m[/tex]

Answer:

Answer:

38 metros

Step-by-step explanation:

Número total de metros que Juan quiere pintar su casa = 200 m

Durante los primeros 2 días, pintó = 33 m todos los días

Por lo tanto, el número total de metros que pintó = 33 m × 2 = 66 m

Al tercer día, practica la pintura = 96 m

El número de metros que quedan por pintar se calcula como:

200m - (66m + 96m)

Los 200m - 162m

= 38m

Step-by-step explanation:

Answer:

66 is equal to K

Step-by-step explanation:

if 4 times 6 equal 24

then 11 time 6 equals 66

in this case, the scale factor is 6.

Have a wonderful day!

Answer:

K = 66

Step-by-step explanation:

[tex]\frac{k}{24} = \frac{11}{4}[/tex]

when taking a look at this, first try to see if you can solve the denominator.

24 to 4 equals 6 meaning you divide k by 6 will be equal to 11

Then 11 x 6 = 66!!

Answer:

18

Step-by-step explanation:

So lets go voer what we know:

There are 6 pieces of ribbon.

Each piece of ribbon is 1 yard long.

We need 1/3 of each ribbon(1/3 yard).

To find this, lets take our 6 pieces of ribbbon, and break them into 3 seperate pieces.

This is because we need ribbons that are 1/3 of a yard. 3 ribbons would make up a single yard.

So:

The 6 yards of ribbon x 3 ribbons that make up 1 yard

6*3

=

18

Answer:

D

Step-by-step explanation:

Since the side length of the square is (2x+5), and squares have equal sides, then you have to do (2x+5)(2x+5). You would get 4x^2+20x+25. That means the answer is D.

Hope this helped!! :D

Answer:

David is 30

Jacob is 9

Step-by-step explanation:

The sum of David and Jacobs age is 39

d + j = 39

d = 39 - j

----------------------

Two years ago David was four times Jacobs age

(d - 2) = 4(j - 2)

d - 2 = 4j - 8

d = 4j - 6

---------------------

Set the equations equal

4j - 6 = 39 - j

5j = 45

j = 9

d = 4(9) - 6

d = 30

Answer:

49 degrees

Step-by-step explanation:

The total of the interior angles of a triange is 180 degrees

You can see that we are already given 2 sides: 41 degrees and 90 degrees (the right angle)

To find the remaining angle, we solve=180=41+90+x

x=49 degrees

Answer:

The center of this circle is (5, -4) and the radius is 1.

Step-by-step explanation:

First regroup these terms according to x and y :

x^2 - 10x + y^2 + 8y = -40

Next, complete the square for x^2 - 10x:  x^2 - 10x + 5^2 - 5^2.

and the same for y^2 + 8y:  y^2 + 8y + 16 - 16

Substituting these results into x^2 - 10x + y^2 + 8y = -40, we get:

x^2 - 10x + 5^2 - 5^2 y^2 + 8y + 16 - 16 = -40.

Next, rewrite x^2 - 10x + 25 and y^2 + 8y + 16 as squares of binomials:

Then x^2 - 10x + 5^2 - 5^2 y^2 + 8y + 16 - 16 = -40 becomes:

(x - 5)^2 + (y + 4)^2 - 25 - 16 = -40, or:

(x - 5)^2 + (y + 4)^2 = 1

This equation has the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.  Matching like terms, we get h = 5, k = -4 and r = 1.

The center of this circle is (5, -4) and the radius is 1.

Answer:

Center (5,-4) Radius = 1

Step-by-step explanation:

Put it in the form of the standard circle equation after dividing everything by 2. (-10x/2=-5x) (8y/2=4y) Since the radius wasn't given, it's just going to be a 1.

(x-5)^2+y(-(-4))^2 = 1^2

Hence, center (5, -4) and radius 1.

Answer:

  x = 2

Step-by-step explanation:

The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.

  (x +4)² = (2x -1)(2x -1 +9)

  0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)

  0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)

This has solutions x = -4 and x = 2. Only the latter works in this geometry.

  x = 2

7, 11, 15, 19 ...

common difference (d) = 11-7 = 4

Recursive rule: A(n) = A(n-1) + d = A(n-1) + 4

Explicit rule: A(n) = A(1) + d * (n-1) = A(1) + 4 *(n-1) = 7 + 4 * (n-1) = 4n + 3

15th term: A(15) = 4 * 15 + 3 = 63
