Find the number a for which x=5 is a solution of the given equation.

Mathematics
1 answer:
vfiekz [6]2 years ago
3 0

Step-by-step explanation:

x + 8a = 25 + ax - 7a

x = 5

5 + 8a = 25 + 5a - 7a

5 + 8a = 25 - 2a

5 + 10a = 25

10a = 20

a = 2

A cylinder and a cone both have radius of 6". The height of the cone is 12". The height of the cylinder is 6". Which has the gre
Shkiper50 [21]

Answer:

cylinder has greatest volume

Step-by-step explanation:

solution

given,

radius of cylinder(r)=6cm

height of cylinder (h)=6cm

we know,

volume of cylinder=πr^2h

=22÷7×6×6×6

=4752÷7

=678.857cm^3

radius of cone(r)=6cm

height of cone(h)=12cm

we know,

volume of cone=1÷3πr^3

= 1÷3×22÷7×6×6×6

= 4752÷21

=226.2857cm^3

as a result,cylinder has greatest volume

How do I solve these for example 3
Natasha2012 [34]
As the three longitudinal lines are parallel:

angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)

and

angle 11 = 180-82= 98 degrees (linear pair)

so:

angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)

D.) A line that has a slope of 3, and goes through the<br> point (2,8); answer in point-slope form.
PIT_PIT [208]

Answer:

y - 8 = 3(x - 2)

Step-by-step explanation:

Start with the basic point-slope form of the equation of a straight line:

y - k = m(x - h).  Here the given point is (2, 8), so assign the value 2 to h and the value 8 to k, also the value 3 to m.  Then:

y - 8 = 3(x - 2)
