30 POINTS AND BRAINLIEST HELP PLZ

Answer:

c.-1

Step-by-step explanation:

log_3 (x+1)-5=-5

log_3 (x+1)=0

(x+1)^3=0

0 to the power of any number is 0 so x=-1

Answer:

Step-by-step explanation:

Correct choice is A

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:8.5

Step-by-step explanation:I just know it’s

Answer:

Step-by-step explanation:

Don't know but I had this same image on my test and I got it right.

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

nothing lol.

Step-by-step explanation:

Answer:

spends more time on swimming

Answer:

7 hr * 12 days = 84 hours

10*84 = 840 man-hrs to build the wall

----

14 men * 8 hr = 112 man-hrs/day

840/112 = 7.5 days

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)

Answer:

         2

Answer:

  not similar

Step-by-step explanation:

For the triangles to be similar, at least two angles must match. Here, there is an 81° angle in both triangles. This means the sum of the remaining two angles must be ...

  180° -81° = 99°

If the missing angle in either triangle matched the other given angle in the opposite triangle, the sum of those would be 60° + 40° = 100°, not 99°. This triangle pair does not have two matching angles, so the triangles are not similar.

ABC angles: 60°, 81°, 39°

FED angles: 59°, 81°, 40°

Answer:

Percent Increase in measure of the side of a square = 30%

Step-by-step explanation:

Let the measure of the side of a square = s

Area of the square = (Side)²

                                = s²

If the area of the square is increased by 69%

Area of the new square = s² + 69% of s²

                                        = s² + 0.69s²

                                        = 1.69s²

Therefore, measure of the side of the new square = √(Area of the square)

                                                                                    = √(1.69s²)

                                                                                    = 1.3s

Measure of side of the old square = s

Therefore, increase in measure of the square = 1.3s - s

                                                                            = 0.3s

Percent increase in the measure of the side of the square

= [tex]\frac{\text{Increase in measure}}{\text{Measure of the side of the original square}}\times 100[/tex]

= [tex]\frac{0.3s}{s}\times 100[/tex]

= 30%
