Make x the subject of formular y=5√x+3-4

Mathematics
1 answer:
pochemuha3 years ago
8 0

Answer:

x={(y+1) / 5}²

Step-by-step explanation:

y = 5√x +3 -4

⇒y = 5√x -1

add 1 on both sides

⇒ y + 1 = 5√x

divide both sides by 5

⇒(y+1) / 5   = (5√x) /5

⇒(y+1) / 5   = √x

now, square both sides

⇒{(y+1) / 5}²  = (√x)²

∴{(y+1) / 5}² = x

You are filling paper cones with popcorn for a party.
Sunny_sXe [5.5K]

Answer:

The amount of popcorn needed to  fill the paper cone is V=1,005\ cm^{3}

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2} h

In this problem we have

r=8\ cm

h=15\ cm

\pi =3.14

substitute

V=\frac{1}{3}(3.14)(8)^{2}(15)

V=1,005\ cm^{3}

Increase 840 in the ratio 2 : 3​
Iteru [2.4K]

Ratios be 2x and 3x

\\ \rm\longmapsto 2x+3x=840

\\ \rm\longmapsto 5x=840

\\ \rm\longmapsto x=\dfrac{840}{5}

\\ \rm\longmapsto x=168

Now

  • 2x=2(168)=336
  • 3x=3(168)=508
