3x - 5y = 20

(5; y)  -  put x = 5 to the equation

3 · 5 - 5y = 20
15 - 5y = 20  |-15
-5y = 5  |:(-5)
y = -1

Answer: (5; -1)

(x; 2)  -  put y = 2 to the equation

3x - 5 · 2 = 20
3x - 10 = 20    |+10
3x = 30    |:3
x = 10

Answer: (10; 2)

Someone want to help me with some Geometry?
Aleks04 [339]
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.

Find the volume of a cone with a base diameter of 12 m and a height of 10 m.
dexar [7]

Answer:

=376.8 m^{3}

Step-by-step explanation:

V=nr^{2}  \frac{h}{3}  Where V is the volume , r is the radius and h is the perpendicular height .

r = \frac{12}{2} m=6

h = 10m

n=3.14

v= 3.14 * 6*6 *\frac{10}{3}

=376.8 m^{3}

HELP MEEEEE PLEASEEEEEE
Sindrei [870]

Answer:

x=16\dfrac{28}{37}\\ \\y=5\dfrac{1}{3}\\ \\z=7.5

Step-by-step explanation:

The diagram shows three paralel lines which divide the large triangle into three similar triangles.

By Thales theorem,

\dfrac{5}{z}=\dfrac{y}{8}=\dfrac{2}{3}

Then

\dfrac{5}{z}=\dfrac{2}{3}\Rightarrow 2z=15,\ z=7.5\\ \\\dfrac{y}{8}=\dfrac{2}{3}\Rightarrow 3y=16,\ y=\dfrac{16}{3}=5\dfrac{1}{3}

From the similarity of triangles,

\dfrac{x}{20}=\dfrac{z+8}{z+8+3}\\ \\\dfrac{x}{20}=\dfrac{7.5+8}{7.5+8+3}\\ \\\dfrac{x}{20}=\dfrac{15.5}{18.5}\\ \\x=20\cdot \dfrac{155}{185}=20\cdot \dfrac{31}{37}=\dfrac{620}{37}=16\dfrac{28}{37}
