Answer:

The minimum number of faces a polyhedron can have is 4 faces.

Step-by-step explanation:

We know that a polyhedron is a shape surrounded by polygons. We also know that we need at least 3 sides to make a polygon. So, at the minimum a polyhedron can be made by using only triangular faces but in order to make a closed figure we need at least four triangular faces (which is a tetrahedron).

Line with a slope 6 passes through the points (2,-10) and (5,g)

Irina-Kira [14]

Answer:

8 =g

Step-by-step explanation:

We have two points so we can use the slope formula

m = ( y2 -y1)/(x2-x1)

6 = ( g - -10)/(5-2)

6 = (g+10)/(5-2)

6 = (g+10)/3

Multiply each side by 3

6*3 = g+10

18 = g+10

Subtract 10

18-10 =g

8 =g

How do you solve this URGENT (50pts)

Aliun [14]

Explanation:

x + 3y = 2

Converting it to slope intercept form:

y = mx + b [where m is slope, b is y-intercept]

Make y the subject:

$\sf \rightarrow 3y = 2 - x$

$\sf \rightarrow 3y = -x + 2$

$\sf \rightarrow y = -\dfrac{x}{3} + \dfrac{2}{3}$

$\sf \rightarrow y = -\dfrac{1}{3} x+ \dfrac{2}{3}$

which reveals slope:

$\star \ slope: \sf - \dfrac{1}{3}$

vic and ben's ages are in the ratio of 3:4. if vic is 12 years old and 3 months old how old is ben in years and months??

posledela

Converting their ages to months:
12*12=144months + 3 months
=147 months
Now, 3 is equivalent to 147 months;
4 will be equivalent to;
4*147/3
= 196 months
= 16 years and 4 months
