Help me with my maths question and you get good luck 10 years

Mathematics
1 answer:
Deffense [45]3 years ago
7 0

Answer:

Step-by-step explanation:

Let all the measurements be in same unit.

200 cm = 2 m

2000 mm = 2 m

Let distance jumped by Jack = x m

Distance jumped by Jerzy = x + 2

Distance jumped by Abdullah = (x+ 2) + 2 = x + 4

Total = 12.69 m

x + x +2 +x +4 = 12.69

x +x + x + 2 + 4 = 12.69

         3x + 6      = 12.69

                  3x = 12.69 - 6

                 3x  = 6.69

                    x = 6.69/3

                    x = 2.23 m

distance jumped by Jack =2.23m

Distance jumped by Jerzy = 2.23 + 2 = 4.23 m

Distance jumped by Abdullah = 2.23 + 4 = 6.23 m

Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side NK.
Leokris [45]

Answer:
NK = 14.4

Step-by-step explanation:

Given the following question:

We know that the two sides are similar
JI = 3, NM = 7.2

<u>The scale factor is 2.4 since....</u>

3\times2.4=7.2


Knowing the two sides are similar and if we multiply JI by 2.4, we get NM we can easily do the same for JG and NK.

JG = 6
6\times2.4=14.4
=14.4

NK = 14.4

Hope this helps.

adoni [48]
Answer is 6-4x

 <span>1/4 evaluates to 1/4
</span>
<span>Multiply x and 16
</span>
<span>Multiply x and 1

after you have the answer it should come out to  </span>24-16x then multiply 1/4 * 24-16x

1/4 *24=6


<span>1/4*(24-16*x) evaluates to 6-4x</span>

Find surface area of rectangular prism
DIA [1.3K]

Answer:

806 yd sq.

Step-by-step explanation:

Area=(length)(width), so to find the surface area you can just find the area of each side and then add then all together.

They already gave you the length of some of the sides, so you should use that to help you find the length of all the sides.

You can see the entire prism's length is 17 yd, width is 4 yd, and height is 14 yd.

The large visible side's area would be (14)(17)= 283 yd. There's another one of these side's on the other side that we can't see. So we would do (283)(2) = 566 yd sq.

Next, we'll find the area of the side on the side by doing (14)(4)=56. Once again, there's two of these sides so we do (56)(2) to get 112 yd sq for this side.

Finally, we'll find the area of the top side. We can do (4)(17) =68, and then (68)(2) to get 138 yd sq.

Now, we have the area of each side of the prism! To find the total surface area, just add them all together. 556+112+138=806.

The surface area would be 806 yd sq.
