I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:

Answers

Answer:

8, 2, 8, 2

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

It’ll always be 8 and 8

surface area of composite figures

Answers

Answer:

408 cm²

Step-by-step explanation:

You can find the total area by dividing the figure into two different parts. You have one large rectangle and two smaller triangles that have the same given dimensions, meaning that the triangles will have the same area. Find the area for the divided figures first.

Rectangle

The length is 24 cm (6 + 8 + 10). The width is 15 cm.

A = lw

A = (24 cm)(15 cm)

A = 360 cm²

Triangle

The height is 6 cm. The base is 8 cm.

A = 1/2bh

A = 1/2(6)(8)

A = 3(8)

A = 24 cm²

Now, add the areas together. Since there are two triangles, make sure to account for that in your calculations.

360 cm² + 24 cm² + 24 cm² = 408 cm²

Answer:

408 cm^2

Step-by-step explanation:

You would just find the surface area of all of the shapes and then add them all together so for the 2 triangles you would just multiply 6 and 8 and divide by 2 so you would get 24 for both of then so then you would find the area of all of the rectangles so for the smallest one you would do 15 times 6 which is 90 then you would multiply 15 and 8 for the middle triangle and that would be 120 and for the last rectangle, you would multiply 15 and 10 which is 150 and then you would add all of them up. The numbers would be 24,24,90,120,150 and when you add them up you would get 408 cm^2

if a $1000 investment earns %20 interest compounded annually, then the investment will double in value in how many years?

Answers

Answer:

In four years.

Step-by-step explanation:

End of first year:

1000 + 20%•1000 = 1000 + 200 = $1200

End of second year:

1200 + 20%•1200 = 1200 + 240 = $1440

End of third year:

1440 + 20%•1440 = 1440 + 288 = $1728

End of fourth year:

1728 + 20%•1728 = 1728 + 345.6 = $2073.6 >2•$1000

Well 100% is 20%x4 so four years So no matter what number it would be 4 years

George is putting trim around his rectangular deck, including the gate. He will need 44 feet of trim to do the entire deck. If the deck is 12 feet long, how wide is the deck?

20 feet
8 feet
22 feet
10 feet

Answers

Answer:

10 feet

Step-by-step explanation:

perimeter of the deck=44 feet

P=2 length+ 2 width

44=2(12)+2w

44=24+2w

2w=44-24

w=20/2 ⇒ w=10 feet

check: P=2l+2w ⇒ 2(12)+2(10) ⇒ 24+20=44 feet

i need step by step explanation for this!

Answers

Answer:

Step-by-step explanation:

13 - 1 = 1212 ÷ 2 = 6Put 6 and 1 together: 61

Therefore, the number is 61

Let's check:

6 × 2 = 1212 + 1 = 13

The sum of the two digits is 13, and we got that, so we are correct. The number is 61.

Answer:

Step-by-step explanation:

let unit digit=x

ten's digit=y

then x+y=13

x=13-y

also x=2y+1

13-y=2y+1

13-1=2y+y

3y=12

y=12/3=4

x=13-4=9

so number =10×4+9=49

What is a point on the line with equation y + 2 = 5 (x - 3) ? (- 3, 2) (- 2, 3) (2, - 3) (3, - 2) are my only choices

Answers

Answer: (3,-2) is a point.

(-2,3) is the point on the line. you can find this by simplifying your equation (subtract 2 from both sides of the equal sign to isolate the y variable). by doing this you get y=3. this means that every point on the line has a 3 in the y spot. therefore, the answer is (-2,3).
