Does anyone know this i am very lost

Step-by-step explanation:

It will pie r squared is equal to area

/ take this sign as pie

/ ×r^2=50/

r^2=50/÷/

r^2=50

r =

[tex] { \sqrt{50} } [/tex]

=

[tex]5 \sqrt{2} [/tex]

The value of the radius of the given circle is 5√2, of which the area is 50π m².

The formula for the area of a circle is A = πr², where A represents the area and r represents the radius.

As per the question, given that the area is 50π m².

So, we can set up the equation as follows:

50π = πr²

To solve for r, we divide both sides of the equation by π:

50 = r²

Taking the square root of both sides, we get:

√50 = √(r²)

Simplifying the square root of 50 gives:

r = √50

r = √(25 x 2)

r = 5√2

Therefore, the value of the radius is 5√2.

Answer:

y intercept is (0,8) and the slope is 2 or 2/1 (its the same thing)

Step-by-step explanation:

i dont know the first answer sorry :( and to find the y-intercept its just where the line crosses the y-axis. slope is just rise over run and you go up 2 and to the right 1, so its 2/1 :) hope this helped!

Answer:

x = 35º

Step-by-step explanation:

(x - 5)°+ (3x)º+ (x + 10)° = 180º

5x + 5 = 180º

5x = (180 - 5 )º

5x = (175 )º

x = 35º

Answer:

Linear equation : y = 2.50h + 5

Step-by-step explanation:

Given that:

Fee for renting roller blades = $5

Per hour charges = $2.50

Let,

h be the number of hours roller blades were rented

y be the total amount

Total amount = Per hour charges * Number of hours + Flat fee

y = 2.50h + 5

Hence,

Linear equation : y = 2.50h + 5

parallel: g(x) = -5/3x + 1

perpendicular: h(x) = 3/5x - 5

neither: j(x) = 2x + 3

Answer: y = -5x + 20

Step-by-step explanation:

Remember that : y=mx+b

y = (-5)x + b

Now you can plug your coordinates (-7,8) into that equation.

8 = (-5)-7 + b

Solve for b

8 = -12 + b

Add +12 to both sides of your equation:

20 = b

Now, your new equation is:

y = -5x + 20

Answer:

44/12

Step-by-step explanation:

When adding fractions, remember that both of the fractions need a common denominator. See below:

11/12 + 11/4 * (3) = 11/12 + 33/12 = 44/12

12 is a common denominator, so you need to multiply 11/4 (both top and bottom) by 3.

Answer:

18

Step-by-step explanation:

Distribute the 7 to get 273=14n+21

Subtract 21 to get 14n=252

Divide by 14 to get 18

Answer:

N=18

Step-by-step explanation:

Distribute~ 273=14n+21

Minus 21 to both sides~ 273-21=14+21-21

Divide your 14 to get rid of your variable~ 14n/14=252/14

Which would equal •18•

Answer:

The Perimeter figure is: 21.42 mm

Step-by-step explanation:

The given figure consists of two parts:

1) Semicircle

2) Square

Determining the Perimeter of the Semicircle:

Given

Diameter d = 6 mm

Radius r = d/2 = 6/2 = 3 mm

In a semi-circle, the perimeter is made up of half the circumference (arc) of the circle and the diameter of the circle.

Perimeter = 1/2 × ( circumference of the circle ) + d

                = 1/2 × (2πr) + d

                = πr + d

                = 3.14(3) + 6

                = 9.42 + 6

                = 15.42 mm

Thus, the Perimeter of the semi-circle is: 15.42 mm

Determining the Perimeter of the Square:

Given

Length of a side = a = 2mm

Perimeter of square = 4a = 4(2) = 8mm

Thus, the Perimeter of the Square is: 8mm

Now, in order to determine the Perimeter of a complete figure, we need to add the Perimeter of the square and the perimeter of the semicircle and subtract 2 mm.

The reason why we need to subtract 2mm because one side of the square (2mm) is overlapped along the diameter of the semicircle.

Now,

Figure Perimeter = Perimeter of square + Perimeter of Semicircle -  2

                             = 8 + 15.42 - 2

                             = 21.42 mm

Therefore, the Perimeter figure is: 21.42 mm

Note: It seems you may have missed adding the correct choice there.

Answer:

Cross Multiply

Step-by-step explanation:

Cross multiplication can help answer these questions.

a. 3x-4/8=x+2/3

step 1- multiply 8 and (x+2), and 3 and (3x-4)

8x+16=9x+12

step 2- Subtract 8x on both sides

16=x+12

step 3- subtract 12 on both sides

4=x, or x=4

b. 3(2-r)/4=3+r/6

step 1- open parentheses

3(2-r)=6-3r

6-3r/4=3+r/6

step 2- cross multiply (put them into a equation without fractions by cross multiplying)

(6-3r) · 6= (3+r) ·4

step 3- multiply

36-18r=12+4r

step 4- solve

add 18r on both sides

36=12+22r

subtract 12 from both sides

24=22r

divide by 22 on both sides

24/22 or 12/11=r

r=12/11

c. 4p+3/8=p+2/4

step 1- cross multiply

(4p+3) · 4= (p+2)·8

step 2- open the parentheses

16p+12=8p+16

step 3- solve

subtract 12 on both sides

16p=8p+4

subtract 8p on both sides

8p=4

divide by  8 on both sides

p=4/8, or p=1/2

d. 2(a-7)/15=a+4/6

step 1- open parentheses

2(a-7) = 2a-14

2a-14/15=a+4/6

step 2- cross multiply

(2a-14) · 6 = (a+4) · 15

step 3- open parentheses

12a-84=15a+60

step 4- solve

subtract 60 on both sides

12a-144=15a

(the answer is -144 because a negative minus a negative such as -80-60=-144.

subtract 12a on both sides

-144=3a

divide by 3 on both sides

-48=a, or a=-48

Answer:

Step-by-step explanation:

First method: for (x+3)^2 if you multiply (x+3)(x+3) you get x^2+6x+9 which doesn't equal x^2+9

Second way:  plug in a variable for example (2+3)^2= 25 and 2^2+9=13 so 13 doesn't equal 25
