POINTS! WILL GOVE BRAINLIEST


PLEASE ANSWER AS MUCH AS YOU CAN <33

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 :)

Minimum-8 Max-42 Median-20 lower quartile-13.5 upper quartile-30

Step-by-step explanation:

Answer:

9840

Step-by-step explanation:

Cubic centimeters used in final wood sculpture = volume of rectangular prism minus volume of triangular prism

To find the volume of a rectangular prism simply multiply the width by the length by the height

The rectangular prism has a given width of 20cm, a given height of 30cm and a given length of 20cm

So volume of rectangular prism = 20 * 20 * 30 = 12,000

Now let's find the volume of the triangular prism she cut out.

To find the volume of a triangular prism we can use this formula

V = bh/2 * l

Where b = base length, h = height of base and l = length of prism

The triangular prism has a given base length of 12cm a given height of 12cm and a given length of 30cm ( we can tell by looking at the image the length of the triangular prism is the same as the height of the rectangular prism.)

We then plug in these dimensions into the formula

V = (12*12)/2 * 30

12 x 12 = 144

144/2 = 72

72 * 30 = 2160

Finally we subtract the volumes

12,000 - 2160 = 9840

We can conclude that the volume of the final sculpture is 9840 cubic centimeters

Answer:

Answer is C because (9+6)÷3 = 5 and from option C u get the same answer

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:

[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]

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:

Step 2: 36 + 21 = 57

Step 3: (36 + 21) x 2= 114

Step 4: 36 + 36 + 21 + 21 = 114

Step-by-step explanation:

Answer:

2. 36 + 21 = 57

3. (36 + 21) x 2 = 114

4. 36 + 36 + 21 + 21 = 114 or 36 x 2 + 21 x 2 = 114

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: the system has no solution because 2x -1 does not wok because e1 dose not have an x at the end

Step-by-step explanation:

Answer:

x + 0.5

Step-by-step explanation:

The sum of implies that addition is involved.

Since the number is unknown, you use a variable. For example, x.

You're adding x and 0.5 so you would use a plus sign.

The algebraic expression would be x + 0.5.

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
