3. A large fruit dish with a 36 in. diameter is placed in the center of a banquet across and is completely filled with apples. T

Serga [27]

Answer:

a) 11%

b) 56%

Step-by-step explanation:

a) A= πr^2 6^2π= 36π A= 18^2π = 324π

36π/324π = .111111111111111111111111 or 11%

remember to cancel out the pi symbols when you are showing your work

(put a line across the pi symbols when dividing)

b) A= πr^2 18^2 π = 324π

A= πr^2 12^2π = 144π

324 – 144 = 180

180π/324π = .5555555555555555555555556 or 56%

Solve with using elimination 3х + 5y = 54 6х +4y = 72

pickupchik [31]

Answer:

y = 6 x=8

Step-by-step explanation:

(3х + 5y = 54)-2 times by -2

6х +4y = 72

-6х + -10y = -108 now combine the equations

6х + 4y = 72

-6y = -36 now divide

y = 6

Plug 6 in 6х +4 * 6 = 72

x=8

Plz i need help walk me through it, thanks

SVETLANKA909090 [29]

Answer:

$p=36^{\circ}$

Step-by-step explanation:

We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is $90^{\circ}$ .

Because all the angles of a triangle sum to $180^{\circ}$ , we have that $p+54+90=180$ .

We combine like terms on the left side to get $p+144=180$ .

We subtract $144$ on both sides to get $p=36$ .

So, $\boxed{p=36^{\circ}}$ and we're done!

The dotted line represents the mid segment of the trapezoid. Find the value of X

Ganezh [65]

Given:

Given that the bases of the trapezoid are 21 and 27.

The midsegment of the trapezoid is 5x - 1.

We need to determine the value of x.

Value of x:

The value of x can be determined using the trapezoid midsegment theorem.

Applying the theorem, we have;

$Midsegment = \frac{b_1+b_2}{2}$

where b₁ and b₂ are the bases of the trapezoid.

Substituting Midsegment = 5x - 1, b₁ = 21 and b₂ = 27, we get;

$5x-1=\frac{21+27}{2}$

Multiplying both sides of the equation by 2, we have;

$2(5x-1)=(21+27)$

Simplifying, we have;

$10x-2=48$

Adding both sides of the equation by 2, we get;

$10x=50$

Dividing both sides of the equation by 10, we have;

$x=5$

Thus, the value of x is 5.
