Answer:

x=3y+15

Step-by-step explanation:

Question:

Which coordinate points match the statement below? Select all that apply.

Every y-value is 4 times greater than the x-value

(4,20)      (2,10)        (8,12)       (7,35)

Answer:

(4,20)      (2,10)    (7,35)

Step-by-step explanation:

Given

y-value = 4 times greater than x-value

Required

Determine the right coordinate points

y is 4 times greater x implies that:

[tex]y = x + 4 * x[/tex]

[tex]y = x + 4x[/tex]

[tex]y = 5x[/tex]

Checking the given coordinates one after the other.

[tex](x,y) = (4,20)[/tex]

[tex]20=5 * 4[/tex]

[tex]20= 20[/tex] --- True

[tex](x,y) = (2,10)[/tex]

[tex]10= 5 * 2[/tex]

[tex]10 = 10[/tex]

[tex](x,y) = (8,12)[/tex]

[tex]12 = 5 *8[/tex]

[tex]12 = 40[/tex] --- False

[tex](x,y) = (7,35)[/tex]

[tex]35 = 5*7[/tex]

[tex]35 = 35[/tex] --- True

Hence, the coordinate points that match are:

(4,20)      (2,10)    (7,35)

It will probably only work if its multiple choice cause you said shaded area and mine just says the area so.

Step-by-step explanation:

2x + 7 > 20

2X+7>20

2X>13

X=13÷2

Answer:

268

Step-by-step explanation:

The volume formula for a sphere is: V= [tex]\frac{4}{3}\pi r^{3}[/tex]

We also know that [tex]\pi[/tex] is approximately 3.14.

You have to know these in order to solve the question..

Since we also know the diameter is 8 we can also find the radius (r) ,which is half of the diamater so 4.

Now all we need to do it plug in the numbers.

V= [tex]\frac{4}{3}[/tex](3.14)[tex]4^{3}[/tex]

Now solve for the equation.

V=267.94...

So rounded that is 268.

Answer:

Step-by-step explanation:

since the two angles are the same we can set up a relationship between the two triangles and set them equal to each other and solve for X  :) , as follows

SOH   sin = Opp / Hyp

triangle 1  )   sin(Ф) = x / 12

triangle 2 )    sin(Ф) = x + 5 / 27

since sin(Ф) is the same for each triangle.. set those other sides equal to each other

x/12 = x+5 /27

now solve for x using your mad algebra skilz  :P

27 / 12 = x + 5 / x

2 3/12  = x/x  + 5/x

2 1/4 = 1 + 5/x

1 1/4 = 5/x

x = 5 / 1 1/4

x = 4   nice  :)

So BD is then

4 + 4+5

so BD = 13  

tell your professor / teacher that you figured it out all on your own  :D

( yes.. that was tricky to figure out )

Answer:

12 x 18 CM.

Step-by-step explanation:

Because 3 cm is 1 ft  so if it is 4 you multiply that by 3 which equals 12 , and for 6 feet you multiply that by 3 cm  and get 18. SO it is 12 x 18 cm.

Step-by-step explanation:

In a right triangle the hypotenuse which is 16+9 =25 has to be the largest side.  Since x is not the hyportenuse it has to be lower which only leaves one answer : 15

Answer:

Step-by-step explanation:

these are tough to solve  , don't feel bad.   soo part of the trick is that the two side set  up similar triangles, then  

16 / y  = y /9     ( the two triangles

16* 9 = [tex]y^{2}[/tex]

144 = [tex]y^{2}[/tex]

12 = y

y is the length between the two triangles , so since we now know that part, we can solve the triangles.

lets use tan to solve one of the angles of the smaller triangle

TOA  to remember how tan fits on a triangle

Tan = Opp / Adj

Tan(Ф) = 9/12

Ф = arcTan(9/12)

Ф = 36.869897

knowing that we can solve for x

use CAH   cos = Adj / Hyp

Cos(36.869897) = 12 /  Hyp

Hyp = 12/ Cos(36.869897)

Hyp = 15   :)  that seems reallly good ..  :P

x = 15   there you go  

Answer:

First find out the other side measurements. Then split the shape into seperate squares and find the area then add them all up.

Step-by-step explanation:

volume is length × width × height.

Answer:

240 cm cubed

Step-by-step explanation:

If you separate the shape into 2 figures, the first figures area is 180

and the second is 60.

180 + 60 = 240

I hope this helps!Let me know if it helps

Next to 71 degrees angle is 45 degrees

The one close to 64 degrees is 64 too ( vertical angles)

And the last one next to 56 degrees is 60

The vertical angles are 56° aech.

Angle next to 56° is: 60° (sum of triangle)

Angle next to 71° is: 45° (sum of triangle)

Vertical angles have equal measure.

In the diagram given, 64 and the opposite angle are congruent because they are vertical angles.

The angle next to 56° is: 180 - 64 - 56 = 60° (sum of triangle)

The angle next to 71° is: 180 - 64 - 71 = 45°.

Answer:

12 yards

Step-by-step explanation:

From. The picture attached, we could obtain the angle of elevation, θ from the curb of the street to the top of the building.

Using trigonometric relation :

Tanθ = opposite / Adjacent

Opposite = 30 yards

Adjacent = 40 yards

Tanθ = 30/40

θ = tan^-1(0.75)

θ = 36.869897°

Distance between curb of street and flagpole :

(40 - 24) yards = 16 yards

Let height of flagpole = h

Tanθ = opposite / Adjacent

Opposite = h yards

Adjacent = 16 yards

Tan36.869897 = h/16

0.75 = h / 16

h = 0.75 * 16

h = 12 yards
