Geometry question building block?

Answer:

14

Step-by-step explanation:

sum of three angles of a triangle is 180

(x-4) + (11x-11) + (x+13) = 180

13x -2 = 180

13x = 182

x=14

Answer:

7/6 or 1.17

Step-by-step explanation:

i made them have a common denominator of 24 and simplified.

hope this is right and helps! :)

Answer:

24

Step-by-step explanation:

8 ÷ 1/3

8/1 ÷ 1/3

8/1 ⋅ 3/1

8 ⋅ 3 = 24

1 ⋅ 1 = 1

24/1 = 24

Answer:

k = 5

Step-by-step explanation:

4 - 5k = -21

Transpose and subtract 4 from both sides:

4 - 4 - 5k = -21 -4

-5k = -25

Divide both sides by -5

-5k/-5 = -25/-5

k = 5

Answer:

[tex]\huge\boxed{7.79 \ \text{feet}}[/tex]

Step-by-step explanation:

We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.

This can be represented as a triangle, where x is the unknown side.

    |\

    |  \

x   |    \      9

    |      \

    |        \                  

    |_____\

    4.5

We can use The Pythagorean Theorem to find the value of x. The theorem states that [tex]a^2+b^2=c^2[/tex], where a and b are the lengths of the legs and c is the length of the hypotenuse.

However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

[tex]a^2 + 4.5^2 = 9^2\\\\a^2 + 20.25 = 81\\\\a^2 = 60.75\\\\a \approx 7.79[/tex]

Answer:

The remainder is -61

Step-by-step explanation:

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

The given polynomial is:

[tex]f(x) = 4x^3 - 6x^2 + 3x + 1[/tex]

We need to find the remainder when f(x) is divided by x+2. According to the above-mentioned theorem, we only need to find f(-2) as follows:

[tex]f(-2) = 4(-2)^3 - 6(-2)^2 + 3(-2) + 1[/tex]

[tex]f(-2) = 4(-8) - 6(4) - 6 + 1[/tex]

[tex]f(-2) = -32 - 24 - 6 + 1=-61[/tex]

The remainder is -61

Answer:

m=13

Step-by-step explanation:

11.50-5.00= 6.50

6.50 divided by .50

= 13 miles

m=13

as long as your numerator is greater than your denominator, it's improper

Given:

The distance s​ (in feet) of the ball from the ground after t seconds is

[tex]s=64t-16t^2[/tex]

To find:

(a) At what time t will the ball strike the​ ground?

(b) For what time t is the ball more than 48 feet above the​ ground?

Solution:

(a)

We have,

[tex]s=64t-16t^2[/tex]

Substitute s=0, to find the time t when the ball strike the​ ground.

[tex]0=64t-16t^2[/tex]

[tex]0=16t(4-t)[/tex]

Using zero product property, we get

[tex]16t=0\Rightarrow t=0[/tex]

[tex]4-t=0\Rightarrow t=4[/tex]

Therefore, the ball strike the​ ground in initial condition (t = 0) and after 4 seconds (t = 4).

(b)

Now, s > 48, to find the time t when the ball will be more than 48 feet above the​ ground.

[tex]64t-16t^2\geq 48[/tex]

[tex]0> 16t^2-64t+48[/tex]

Divide both sides by 16.

[tex]0> t^2-4t+3[/tex]

[tex]0> t^2-t-3t+3[/tex]

[tex]0> t(t-1)-3(t-1)[/tex]

[tex]0>(t-1)(t-3)[/tex]

Related equation is [tex](t-1)(t-3)=0[/tex]. Zeroes are t=1,3. These two number divide the number line is three parts. (-∞,1),(1,3),(3,∞)

[tex]0>(t-1)(t-3)[/tex] inequality is true for only (1,3).

It is only possible when t lies in the interval (1,3).

Therefore, the ball will be more than 48 feet above the​ ground between 1 and 3 seconds.
