Mathematics
1 answer:
Alenkasestr [34]3 years ago
8 0

Answer:

either 76 or 19

Step-by-step explanation:

76 if it's 1/5 of the original amount as well as 3/4 the original amount

1/5+3/4=19/20

3.80=1/20x

3.80+19/20x=76

3.8*20=76

19 if it's 1/5 of the original amount and 3/4 of the new amount

3.80=1/4y

3.80+3/4y=15.20

15.20=4/5x

15.20+1/5x=19

State the third congruent part to prove the two triangles congruent by SSS. Write the triangle congruence statement
Alekssandra [29.7K]

Answer:

  • ΔCBA ≅ ΔDEF

Step-by-step explanation:

The question in text and on the picture are different.

Going by picture.

When stating the congruence, it is important to stick to right order of vertices.

The first triangle is ΔCBA

<u>Corresponding angles are:</u>

  • ∠C ≅ ∠D, ∠B ≅ ∠E, ∠A ≅ ∠ F

<u>Therefore the second triangle is:</u>

  • ΔDEF

Find vertex of f(x)=(x+3)(x-5)
astra-53 [7]

The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.

Answer: (1, -16)

Let's do it some other ways.  How about completing the square to turn f in to vertex form?

f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16

and now we can read off (1, -16) as the vertex.

The other method is the vertex is x= - b/2a =  - (-2)/2(1) = 1.

Three methods, same answer. Good.

Find the volume of the rectangle 4 2/3cm,9 1/8cm, 2cm
amm1812

Answer:

\large\boxed{V=85\dfrac{1}{6}\ cm^3}

Step-by-step explanation:

The formula of a volume of a rectangular prism:

V=lwh

l - length

w - width

h - height

We have

l=4\dfrac{2}{3}\ cm=\dfrac{4\cdot3+2}{3}\ cm=\dfrac{14}{3}\ cm\\\\w=9\dfrac{1}{8}\ cm=\dfrac{9\cdot8+1}{8}\ cm=\dfrac{73}{8}\ cm\\\\h=2\ cm

Substitute:

V=\dfrac{14}{3}\cdot\dfrac{73}{8}\cdot2=\dfrac{7}{3}\cdot\dfrac{73}{2}\cdot1=\dfrac{511}{6}=85\dfrac{1}{6}\ cm^3
