Answer: 12.12 m

Step-by-step explanation:

Given

length of ladder L=14 m

the ladder makes an angle of [tex]\theta=30^{\circ}[/tex] with the building

With the help of a diagram, we can write

[tex]\cos \theta=\frac{\text{h}}{\text{L}}[/tex]

[tex]\cos 30^{\circ}=\frac{h}{14}[/tex]

[tex]h=14\cos 30^{\circ}[/tex]

[tex]h=12.12\ m[/tex]

Additional comments

It usually works best if you can identify points on the graph where the line crosses grid intersections. Then the number of squares in each direction can be counted easily. If you work with two grid intersections that are closest together, then the ratio of rise to run will already be in reduced form.

On this graph, there are other grid crossing points that are 4, 6, 8 units to the right or left of the one where we started. You need to remember that "run" is positive in the "right" direction, and "rise" is positive in the "up" direction.

We have shown the "rise" and "run" lines above the graphed line. They can also be shown below the graphed line.

Here, the grid squares are 1 unit in each direction. You need to pay attention to the scale, because some graphs have different numbering vertically than horizontally. The values for "rise" and "run" need to be figured using the appropriate scale.

first do (x + 6)(x+6)

= (x^2 + 6x + 6x + 36)

multiply all by 2

2x^2 + 12x + 12x + 72

simplify and subtract 50

Answer:

1- sqrt/2 = (2-sqrt2)/2

x = arctan((2-sqrt2)/2) = 16.32495 degrees

Answer:

117 units

Step-by-step explanation:

if you use the ratio of the two longest sides then you can find all side lengths

[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{10}[/tex];    x = half of 52, or 26

[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{15}[/tex];    20x = 52 · 15

              20x = 780

               x = 39

add to get perimeter: 52 + 26 + 39 = 117 units

Perimeter of the larger triangle is 117 units

Given

Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units.

When the triangles are similar then the sides are in proportion

the longest side of the smaller triangle is 20 units

The larger triangle's longest side is 52 units.

Lets find out the unknown sides of largest triangle

Let x  and  y be the unknown sides . Make a proportion and solve for x  and y

[tex]\frac{52}{20}=\frac{x}{10} \\x=\frac{52}{20} \codt 10\\x=26\\\\\\\frac{52}{20}=\frac{y}{15}\\y=\frac{52}{20} \codt 15\\y=39[/tex]

The unknown sides of largest triangle is 26 and 39 units

To find out the perimeter add all the sides of largest triangle

Perimeter =[tex]26+39+52=117[/tex]

Perimeter of the larger triangle is 117 units

Answer:

2x+3y+5=0

a = 2  b = 3  c=5

Step-by-step explanation:

We are asked to express 2x+3y=-5 in the form ax+by+c=0

Add 5 to both sides

2x+3y+5=0

We can now find the values of a, b and c now that the equation is in standard form.

Answer:

47 degrees

Step-by-step explanation:

Answer:

B. 47 degrees

Step-by-step explanation:

/_wxy = 56

/_xyw = 68

/_xwy = 180 - (56 + 68) = 56

[interior angles of a triangle =180]

/_wzv = 77

/_vwz = 56

[/_xwy = /_ vwz]

/_zvw = 180 - (77 + 56) = 47

Joan has 32$. And makes 4$ every hour of mowing lawns.

60-32=28.

So what we will do to solve this problem is multiply 7 by 4.

7x4= 28.

32+28=60.

This means that Joan needs to work 7 hours in total to earn $28.

If  If Mike has $6.00 in quarters and nickels, then the number of nickels Make have are 60.

Let's assume that the number of nickels in Mike's cup is "N." Since Mike has 20% as many quarters as nickels, the number of quarters can be expressed as 0.20N.

Now, we know that the total value of the quarters and nickels is $6.00. The value of each nickel is $0.05, and the value of each quarter is $0.25.

So, we can set up the equation:

0.05N + 0.25(0.20N) = 6.00

Now, let's solve for N:

0.05N + 0.05N = 6.00

0.10N = 6.00

N = 6.00 / 0.10

N = 60

So, Mike has 60 nickels in his cup.

Answer:

(- 3, 0 ), (4, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0

[tex]\frac{x^2-x-12}{5x^2+ 4x}[/tex] = 0

The denominator cannot equal zero as this would make f(x) undefined.

Equate the numerator to zero and solve for x

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

x- intercepts are (- 3, 0 ) and (4, 0 )

Answer:

9 weeks

9 = w

let the num be a

/a÷5=20

/a=20×5

/a =100

square root of 100 is 10

so the number is 10

The number that she have to think of should be considered as the 10 when her answer is 20.

Since here we assume the number be a

And, now she have to determine the square root and then divide it by 5

So, it can be like

[tex]a\div 5=20\\\\a=20\times 5[/tex]

a =100

Now the square root of 100 should be 10

hence, a = 10

Therefore, The number that she have to think of should be considered as the 10 when her answer is 20.

Answer:

21

Step-by-step explanation:

Well you basically divide 3 and 1/2 by 1/6 which you would you have to simplify the 3 and 1/2 which is 7/2 and switch the denominator and numerator of the 1/6 which would be 6/1 and after you multiply(7/2 x 6/1=42/2) it would be 42/2 which you would have to simplify by dividing 42 and 2 which is 21. There you go I hope this helps.

Answer:

21.

Step-by-step explanation:

That would be  3 1/2 divided by 1/6.
