Answer:

Step-by-step explanation:

Perimeter of Square = 40 cm

4*side = 40

side = 40/4

side = 10 cm

Area of shaded region= Area of square - [Area of triangle 1 + Area of triangle 2]

$=[side*side]-[\frac{1}{2}*b*h+\frac{1}{2}*b*h]\\\\=[10*10]-[\frac{1}2}*3*10+\frac{1}{2}*10*6]\\\\=100-[3*5+5*6]\\\\=100-[15+30]\\\\=100-45\\\\=55cm^{2}\\$

Percentage = (55/100)*100=55%

Solve for x and y. Geometry

Otrada [13]

Answer:

x =106.5

y = 73.5

Step-by-step explanation:

Angle x is 1/2 arc SPQ

x = 1/2(98+115)

x = 1/2(213)

x =106.5

We know that x+y = 180 since this is an inscribed quadrilateral in a circle

x+y=180

106.5 +y =180

Subtract 106.5 from each side

106.5-106.5 +y =180-106.5

y = 73.5

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi

omeli [17]

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is $R=log_{10}(S)$

Where,

R is the measurement in Richter Scale
S is the relative size of the earthquare

It is given that in Richter Scale, an earthquake measured 3.2, so $R=3.2$ .

They want to know relative size, S, so we put given information in equation and solve for S:

$R=log_{10}(S)\\3.2=log_{10}(S)$

Converting to exponential form, we have:

$3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932$

Rounding to nearest hundredth, we have:

$S=1584.89$

What is the quotient of <img src="https://tex.z-dn.net/?f=2%20%5Cfrac%7B2%7D%7B7%7D%20%20%5Cdiv%20%20%5Cfrac%7B4%7D%7B7%7D%2

$2 \frac{2}{7}$ ÷ $\frac{4}{7}$

First, let's turn the first fraction into an improper fraction.

$\frac{16}{7}$ ÷ $\frac{4}{7}$

Since both of these fractions share the same denominator, we can drop the denominator and simply divide the numerators.

16 ÷ 4 = 4

The quotient = 4
