Someone help I don't know what the diameter or radius is

Elenna [48]

<h3>Answer:</h3>

52.38 inch² & 261.90 inch²

<h3>Step-by-step explanation:</h3>

Here we need to find the area of the sector . So according to formula we know the area of sector as ,

$\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }$

Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,

=> Area = ∅/ 360° × π r²

=> Area = 60°/360° × 22/7 × (10in.)²

=> Area = 1/6 * 22/7 * 100 in²

=> Area = 52 .380 in²

<h3>★ Hence the area of the red sector is 52.38 inch².</h3>

_________________________________

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .

=> Area = 300/360 × 22/7 × 100 in²

=> Area = 261. 90 in²

<h3>★ Hence the area of blue sector is 261.90 inch².</h3>

$\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}$

$\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}$

Sloope intercept form is
y=mx+b
m=slope
b=y intercept =where the line passes through the y axis

we are given
line M has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2

line N has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2

compare

line M: y=x-2
line N: y=x-2

they are the same line and lines extend infinitely so therefor there are infinite number of solutions

Find two numbers such that the sum of the first and three times the second is 5 and the sum of the second and two times the firs

Sav [38]

Answer:

first number= 19/5

second number= 2/5

Step-by-step explanation:

first number= a

second number= b

a+3b=5 equation 1

b+2a=8 equation 2

using equation 2 we have

b=8-2a

using equation 1 we have

a+3(8-2a)=5

a+24-6a=5

24-5=6a-a

19=5a

a=19/5 = first number

so using b=8-2a

we have

b=8-2(19/5)

b=8-(38/5)

b=2/5 = second number
