2 answers:

7 0

725 is 15% of something
'of' means multipliy
percent means parts out of 100 so
15%=15/100=0.15
725=0.15 times something
divide both sides by 0.15
4833.33333333333333333333333333 to infinity
round to the hundreth's place
4833.33

15%=0.15
n=unknown number
725=0.15n
725 divided by 0.15=n
4833.33333(goes on forever)=n
So 725 is 15% of 4833.3333339(goes on forever)

Madelyn hikes 190.5 meters up a mountain. If she is 62% of the way up, how tall is the mountain? Round to the nearest whole met

likoan [24]

190.5 / 62 = x / 100

19050 / 62 = 307 if you round

Solve 3x^2=-12-6x by completing the square

Lelu [443]

Answer:

x = - 1 ± i $\sqrt{3}$

Step-by-step explanation:

Given

3x² = - 12 - 6x ( add 6x to both sides )

3x² + 6x = - 12 ( divide through by 3 )

x² + 2x = - 4

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = - 4 + 1

(x + 1)² = - 3 ( take the square root of both sides )

x + 1 = ± $\sqrt{-3}$ = ± i $\sqrt{3}$ ( subtract 1 from both sides )

x = - 1 ± i $\sqrt{3}$

50 points!! Please help!! Will mark brainliest and random answers will be reported

Triss [41]

Answer:

In the above figure

both the sides are equal then angle between them will also equal

so,

(2x+2) + (2x+2) + (3x+1) = 180

7x + 5 = 180

7x = 175 

x = 175/7

x = 25

hence angle will (25 *2) +2 =52

other angle is( 25*3)+1 = 76

hope it helps and your day will fine
