Help Me With This Question Please!
Andrej [43]

Answer:

∠AOB = 120°

∠BOC = 140°

∠BOD = 140°

Step-by-step explanation:

First, find X !

Full circle is 360°

360 = (2x + 80) + (5x + 40) + 4x + x

360 = 12x + 120

240 = 12x

x = 20°

Substitute the X

∠AOB ≡ (2x + 80) =

(2(20) + 80) = 120°

∠BOC ≡ (5x + 40) =

(5(20) + 40) = 140°

∠BOD = ∠AOB + ∠DOA ≡

120 + x = 120 + 20 = 140°

What is 21 1/4% expressed as a fraction?
Neporo4naja [7]

Answer:

\frac{17}{80}

Step-by-step explanation:

we have

21\frac{1}{4}\%

Convert mixed number to an improper fraction

21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}

so

21\frac{1}{4}\%=\frac{85}{4}\%

Convert percent number as a fraction

\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}

Simplify

Divide by 5 both numerator and denominator

\frac{17}{80}

What is the volume of this cuboid?<br>Please help me!!!?!
Snowcat [4.5K]

The formula of a volume of a cuboid:

V=lwh

l - length

w - width

h - height

We have:

l = (x + 4) cm

w = (x + 1) cm

h = 3 cm

Substitute:

V=(x+4)(x+1)(3)      <em>use distributive property</em>

V=(x+4)(3x+3)

V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)

V=3x^2+3x+12x+12      <em>combine like terms</em>

\boxed{V=3x^2+15x+12}
