Answer:

56.73 ft

Step-by-step explanation:

Given:

51° (angle)

73ft (hypotenuse)

With the given information use sin to determine the height of the kite.

sin51° = x/73

solve for x (height)

x= 73*sin51°

x= 56.73ft

Answer:

David's height is 57 inches.

Step-by-step explanation:

x/11=55

x=605

x/10=54.8

x=548

605-548=57

Answer:

57 inches

Step-by-step explanation:

undo the problem

4 or 2.5

Step-by-step explanation:

x+2x=3x

12/3=4=x

13+1=14

14/2=7=y

13+/-3=16/10

16/4=4

10/4= 2.5

this one depends wether 3 is negative or positive

Answer:

7

Step-by-step explanation:

The square root of 49 is 7

Answer:

x=15°

Step-by-step explanation:

We can see angle 6x-5 has a corresponding angle above it, which is congruent to it. That angle is supplementary with angle 7x-10. We can tell because it forms a straight angle with it. Supplementary angles add to 180°.

(7x-10)+(6x-5)=180

7x-10+6x-5=180

13x-15=180

13x=195

x=15

Answer:

Step-by-step explanation:

Step-by-step explanation:

Okay, the first step is to rewrite this equation in "vertex form." You can search that up but it's basically just (h/k).

y = ( x − 1) 2 + 3

Now, we are going to use the vertex form, "y = a (x - h)2 + k, to get the values of a, h, and k.

By using the form we get 1 for the value a, 1 for the value h, and 3 for the value k.

1 = a

1 = h

3 = k

Becuse the value of a is positive, the parabola opens up!  (A parabola is the U shaped line in a graph, so that opens up.)

Now, we find the vertex (h,k)

which is (1,3)

Now we find the p from the vertex to the focus.  (vertext the top, focus one of the points.)

Follow this formula to find the distance from the vertex to a focus by using this formula

1/4a.

Now we just gonna substitue 1 for a, since we know that 1 equals a above ^

1/4 * 1

Solving that, we got a nice little 1/4.

Next we find the focus

"Find the focus.

The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.

(h,k+p)

Substitute the known values of h, p, and k into the formula and simplify.

(1,134)

Find the axis of symmetry by finding the line that passes through the vertex and the focus.

x=1

Find the directrix.

y=114

Use the properties of the parabola to analyze and graph the parabola.

Direction: Opens Up

Vertex: (1,3)

Focus: (1,134)

Axis of Symmetry: x=1

Directrix: y=114

Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.

xy−1704132437

Graph the parabola using its properties and the selected points.

Direction: Opens Up

Vertex: (1,3)

Focus: (1,134)

Axis of Symmetry: x=1

Directrix: y=114

Step-by-step explanation:

i used this formula in the screenshot

and you can also try using calculator websites

Answer:

A. 5.25

Step-by-step explanation:

4.5 + 6 = 10.5

15.75 - 10.5 = 5.25

4.5 + 6 + 5.25 = 15.75

Answer:

1. a - 5 years

2. a × 3 =3a years

3. a + 4 years

4. 2|3×a = 2a|3 years

5. 2×a+3 = 2a+3 years

==========================================================

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

[tex]\frac{OK}{KY} =\frac{OC}{RY}[/tex]

[tex]\frac{12}{24} =\frac{OC}{96}[/tex]

[tex]24OC=1152[/tex]

[tex]OC=48[/tex]

[tex]\frac{KC}{RK} =\frac{OK}{KY}[/tex]

[tex]\frac{50}{RK} =\frac{12}{24}[/tex]

[tex]12RK=1200[/tex]

[tex]RK=100[/tex]

Answer:

RK = 100

OC = 48

Step-by-step explanation:

Scale factor = 12/24 = 1/2

1/2 RK = 50

RK = 2* 50

RK = 100

1/2 RY = OC

1/2 * 96 = OC

48 = OC

OC = 48

Answer:

$50,000

Step-by-step explanation:

We have an average of 10 livestock units per hectare

The number of units in 250 hectares will be;

250 * 10 = 2,500 units

Amount earned per unit is $20 per year

So, for 2,500 units, we have

2500 * $20 = $50,000

Answer:

Solution given:

x(w – 1) + (W – 1)

distribute it:

xw-x+w-1

xw+w-x-1

take common from each term

w(x+1)-1(x+1)

take common again

(x+1)(w-1)

the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).

Answer:

C) 25.13

Step-by-step explanation:

The formula for circumference is 2(pi)r.

In order to find r, or the radius, we can divide the diameter by 2.

d/2=r

8/2=4

r=4

Plug the radius into the formula

2(pi)4

And finally, plug it into your calculator.

2(pi)4 = ~25.13

Step-by-step explanation:

I think the choose 3 (g , h ,f )

So supplementary angles are ones that add up to 180degrees and complementary ones add up to 90degrees.

So for the left side, you find what angle is supplementary to the given one. For the angle of 35, another angle of 145 will add up to 180.

The right side want you to find the complementary angles, so for the angle of 18, another angle of 72 will add up to 90.

I always forget supplementary vs complementary, but a little bit of practice will help a lot.
