Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

<ADB + <BDC = 180°

IT'S seen that BOTH ADB and BDC are 90 degrees

90+90= 180

What equation, in point-slope form, matches the graphed line shown? Question 3 options: y−5=−23(x+9) y−2=−34(x−6) y+6=45(x+3) y−
ziro4ka [17]

Step-by-step explanation:

the line passes through (6, 2) and (10, -1),

the slope =

(-1-2)/(10-6) = -3/4

the equation :

y-2 = -3/4(x -6)

The vertex angle of an isosceles triangle measures ( 6x -9)° and one of the base angles measures (4x)°. What is the value of x?
Gnom [1K]

Answer:

x = 13.5

Step-by-step explanation:

We know that base angles of an isosceles triangle are equal. The base angles of the triangle are (4x)° each. The vertex angle of the traingle is (6x-9)°. So according to angle sum property of triangle,

6x - 9 + 4x + 4x = 180

=  > 6x - 9 + 8x = 180

=  > 14x - 9 = 180

=  > 14x = 180  + 9 = 189

=  > x =  \frac{189}{14}  = 13.5

Given A = {x ∈ ℤ : 4|x} and B = {x ∈ ℤ : 2|x}. Prove A ⊆ B.
Rashid [163]

Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.

We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.

Therefore A ⊆ B.

Answer: 12,8 approximately 13 cones

Step-by-step explanation:

1] volume of a cone

V=1/3πr^2h

V=1/3π(3)^2(5)

V=47,12 cubic inches

2] volume of a cylinder

V=πr^2h

V=π(8)^2(3)

V=603.19

Now devide the volume of a cylinder by the volume of a cone

603,19÷47,12=12,8 cones
