Answer:

Its impossible to solve the question

Step-by-step explanation:

If the measurements of all the rectangles was given we could calculate the answer however some of them dont have the measurements making us unable to solve it

Answer:

The answer to A is 6 The answer to B is more complicated

Step-by-step explanation:

B : area = 18

36 =2x18

36= 3x12

36=4x9

The triangle can have dimensions in the form of bxh in 36 =2x18 or 36= 3x12 or 36=4x9

(5,3), (3,2).

Answer:

no solution

Step-by-step explanation:

a solution would mean a point where the two lines cross. theres no such thing for parallel lines.

but if the lines are the same, they are parallel and cross everywhere, that would give infinite solutions.

if they would cross once, it would mean one solution

Answer:

First question would be B

and second on would be C

Step-by-step explanation:

Answer:

(4,5)

Step-by-step explanation:

5x+y=25 equation 1

-3x+2y=-2 equation 2

y=25-5x isolate y from equation 1

-3x+2(25-5x)=-2 substitute y value into equation 2

-3x+50-10x=-2

-13x=-52

x=4

solve for y by inserting x value into either equation.

5x+y=25

5(4)+y=25

20+y=25

y=5

Answer:

[tex]\text{B. }86.7}[/tex]

Step-by-step explanation:

The total surface area of the square pyramid consists of one square and four congruent triangles. By adding the total area of each, we get the total surface area of the square pyramid.

Area of the square: [tex]5.1^2=26.01[/tex]

Area of four triangles: [tex]4\cdot \frac{1}{2}\cdot 5.95\cdot 5.1=60.69[/tex]

Therefore, the total surface area of the pyramid is [tex]26.01+60.69=\boxed{\text{B. }86.7}}[/tex]

4L + πr

Step-by-step explanation:

Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.

The perimeter of a square which is the distance around the square is given by 4L where L is the side length.

The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr

(b) The diameter of the semi-circle is 17 meters.

(c)  To enclose the entire yard and keep Sprinkles from running away, the fencing needs to be 8.5π + 68 meters.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given that Laura’s yard is in the shape of a square and a semi-circle.

The side of the square is 17 meters.

(b). To find the diameter of the semi-circle:

The diameter of the semi-circle = side length of a square.

The diameter of the semi-circle is 17 meters.

(c). To enclose the entire yard and keep Sprinkles from running away,

the total perimeter = the perimeter of the square + the perimeter of the semi-circle

= 4(17) + π(8.5)

= 8.5π + 68 meters

Therefore, the perimeter is 8.5π + 68 meters.

Answer:

$520.96

Step-by-step explanation:

This is a compound shape made of 1 rectangle and two semi circles which makes 1 full circle.

Area of Rectangle = L x W

Area of circle is =pi x radius squared

Area of Rectangle is 5ft x 4ft = 20 ft squared.

Area of circle is = 12.56 ft squared

- Diameter of the circle is 4ft, radius is 1/2 diameter

- Radius is 2ft, 2 x 2 = 4ft

(pi) 3.14 x 4ft = 12.56 ft squared.

As it is a compound shape you need to add

Area of Square + Area of circle =

20 ft squared + 12.56 ft squared =

Total Area of window is 32.56 ft squared

$16 = 1 square foot

$16 × 32.56 = $520.96

Answer:

Hi, there I'll help you since no one helped you which I felt sad lol, but anyway here's your answer

x=2,y=7→ y=11-2x;4x-3y=-13

x=5,y=2→ 2x+y=12;x=9−2y

x=3,y=5→ y=10+x;-3x+3y=30

x=7,y=3→ x+3y=16;2x−y=11

Hope this helps :)
