What ordered pair is a solution of the equation y-3=5(x-2)

RideAnS [48]

Answer:

(0,-7)

Step-by-step explanation:

In this question, we need to find an ordered pair of (x,y)

First we need to solve the equation for Y. It will be:

y-3=5(x-2)

y=5x-10 +3

y= 5x -7

Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be

y= 5x-7

y= 5(0) - 7

y=-7

The ordered pair will be: (0,-7)

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees

asambeis [7]

Answer:

The temperature is $50^{\circ}F$

Step-by-step explanation:

Given

$F= (C*1.8) + 32$

Required

Find F when $C = 10$

$F= (C*1.8) + 32$

Substitute 10 for C

$F = 10 * 1.8 + 32$

$F = 18 + 32$

$F = 50$

The diagram shows a square ABCD with sides of length 20cm. it also shows a semi circle and an arc circle AB is the diameter of t

Brut [27]

Answer:

Area of Shaded Region $=50\pi$ cm^2$

Area of Semicircle $=50\pi$ cm^2$

$\dfrac{\text{Area of Shaded region}}{\text{Area of Square}}=\dfrac{ \pi}{8}$

Step-by-step explanation:

Area of Shaded Region = Area of Sector - Area of Semicircle

<u>Area of Sector</u>

Radius of the sector =20cm

$=\frac{90}{360}X\pi *20^2\\ =100\pi cm^2$

<u>Area of Semicircle</u>

Since AB is the diameter of the semicircle

Radius of the Semicircle=20/2=10cm

Area of semicircle

$=\frac{\pi r^2}{2}\\ =\frac{\pi *10^2}{2}\\=50\pi cm^2$

Therefore, area of Shaded Region

$=100\pi -50 \pi\\=50\pi$ cm^2$

Area of Square =20 X 20 $=400 cm^2$

$\dfrac{\text{Area of Shaded region}}{\text{Area of Square}} \\=\dfrac{50 \pi}{400} \\=\dfrac{ \pi}{8}$
