Answer:

41.13m

Step-by-step explanation:

To find the area of a circle, use A= πr²

A(of circle) = π * 4²

A(of circle) = π * 16

A(of circle) ≈ 50.2655

Because you only have 2 quarters of a circle, you multiply it by 2/4

A(of 2/4 circle) ≈ 25.13275

A of rectangle = l * w

A(of rectangle) = 4 * 4

A(of rectangle) = 16

16+25.13275 = 41.13275

or 41.13

Answer:

41.13 sq m

Step-by-step explanation:

area of square = 4² = 16

there are two quarter-circles which equals one semicircle

area of semi-circle is πr²/2

A = 4²π/2 = 8π = 25.13

add together: 16 + 25.13 = 41.13

Quinzel and Joseph sell shoes. Last month Quinzel sold 18 less pairs

hichkok12 [17]

Answer:

Quinzel sold 17 pairs of shoes last month.

Step-by-step explanation:

Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.

Set up a system of equations:

$\left \{ {{Q=J-18} \atop {Q+J=52} \right.$

Solve for "J" from the first equation:

$J=Q+18$

Applying the Substitution Method, you get:

$Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17$

Find the equation of the line passing through the points (5,21) and (-5,-29)

Assoli18 [71]

Answer:

Look below

Step-by-step explanation:

lets have -29 be y2 and -5 be x2

21 - (-)29

5 - (-)5

Subtracting a negative is just adding it so

21 + 29 50
5 + 5 10

50/10

this simplified, is 5/1 or 5

y=5x+b

now we need to find b, so we substitute y and y

x = 5

y = 21

21=5*5=b

5*5 is 25

now we need to get to 21

25 -4 is 21

b = -4

y=5x-4

Put the following equation of a line into slope-intercept form, simplifying all fractions. 5x+6y=42

Sever21 [200]

Answer:

$y=-\frac{5}{6} + 7$

Step-by-step explanation:

Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.

1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.

$6y=-5x+42$

2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:

$y=-\frac{5}{6} + 7$

Can someone plz help me ty

Ostrovityanka [42]

Answer:

8/15

Step-by-step explanation:

you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1

then you multiply across

2/15 * 4/1

you first multiply 2 and 4 and your answer will be 8 which is the numerator

then multiply 15 and 1 which is 15, the denominator

then you get

8/15
