Answer:

112

Step-by-step explanation:

This is a cyclic quadralterial. A cyclic quadralterial is a quadralterial that is inscribed in a circle where all the point or vertices of the quadralterial touches the circle circumference. Opposite angles in a cyclic quadralterial are supplementary.

Angle R and Angle QPS or P is supplementary since they are opposite angle.

Substitute 68 for R

68 + qps = 180

qps = 112

So the answer is 112

Answer:

33%

Step-by-step explanation:

This question involves working with areas.

The area of a circle is πr².

With this in mind, let's proceed to label our circles.

From order of smallest to largest, we'll label them A, B and C.

Area for circle A = π(4)² = 16π

Area for circle B = π(4+3)² = π7² = 49π

Area for circle C = π(4+3+3)² = π10² = 100π

Now let's label the rings.

The blue shaded area will be ring K and the outer, larger, ring, L.

To find the area of ring L, we must subtract the area of B from C.

L = C - B

L = 100π - 49π

L = 51π

Now to find the area of ring K, we'll subtract the area of our circle A, and our ring L.

K = C - A - L

K = 100π - 16π - 51π

K = 33π

We now know that the blue shaded area has a total area of 33π. We also know that the full area of the logo is the same area of Circle C, 100π. To find the percentage, we simply divide.

Percentage of K = \frac{K}{C}

Percentage of K = \frac{33\pi}{100\pi}

Percentage of K = \frac{33}{100}

Percentage of K = 33%

What is the diameter and radius?​
vesna_86 [32]

Circumference C=2pi*r

But in question C=40pi

This implies that 2pi*r=40pi

This implies that r=20 in.

d=2*r=40 in.

Hope this helps :)

What value of p makes the equation true?<br> -3p + 1/8 = -1/4
makkiz [27]

<em>Answer:</em>

<em>p = 1/8</em>

<em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>⁸⁾-3p + 1/8 = ²⁾- 1/4</em>

<em>- 24p + 1 = - 2</em>

<em>- 24p = - 2 - 1</em>

<em>- 24p = - 3 | (-)</em>

<em>24p = 3</em>

<em>p = 3⁽³/24</em>

<em>p = 1/8</em>

<em>Good luck !</em>

A newspaper and three hot chocolates cost $7. Two newspapers and two hot chocolates cost $6. How much does one hot chocolate cos
pochemuha

Answer:

the cost of one hot chocolate is $2.

Step-by-step explanation:

Let x be the hot chocolate cost and y be the newspaper cost.

Given:

A newspaper and three hot chocolates cost $7

So, the equation is

3x+y=7--------(1)

Two newspapers and two hot chocolates cost $6

So, the second equation is.

2x+2y=6---------(2)

Find one hot chocolate cost?

Solve equation 1 for y.

3x+y=7

y=7-3x

Put y value in equation 2

2x+2(7-3x)=6

2x+14-6x=6

14-4x=6

-4x=6-14

-4x=-8

negative sign is cancelled both side.

x=\frac{8}{4}

x=2

Therefore, the cost of one hot chocolate is $2.
