Answer:

Height = 14.4

Step-by-step explanation:

The diagonals meet at right angles. Interesting property.

The hypotenuse is the side of the rhombus = 15 cm

One of the sides of the small triangles created by the intersection of the diagonals = 24/2 = 12

You can find the other side of the the triangle by using the Pythagorean Theorem

a^2 + b^2 = c^2

c = 15

a = 12

b = ?

12^2 + b^2 = 15^2

144 + b^2 = 225

b^2 = 225 - 144

b^2 = 81

b = 9

The area of this right angle = 9 * 12/2 = 54

There are 4 of them so 4 * 54 = 216

That's the area of the rhombus.

The h= Area / b

b = 15

h = 216/15

h = 14.4

What is 2 2/15 - 1 2/3=<br> I ended up with 2 3/21 <br> Really need help with this!
QveST [7]

Answer:

2 \frac{2}{15}  - 1 \frac{2}{3}

=  \frac{32}{15}  -  \frac{5}{3}

=  \frac{32 \times 1 - 5 \times 5}{15}

= \frac{32 - 25}{15}

=  \frac{7}{15}

Complete the table:<br> 6,000<br> meters<br> kilometers<br> 8,000<br> 9,000<br> 5<br> 7
Alex17521 [72]

Answer:

Remember while answering, 1 kilometer = 1,000 meters

5,000 ⇒ 5

6,000 ⇒ 6

7,000 ⇒ 7

8,000 ⇒ 8

9,000 ⇒ 9

Step-by-step explanation:

1 kilometer is 1,000 meters because "kilo" means 1,000

Knowing this we can make an equation to figure this out

When we know x, or meters, we can do y = x/1,000

When we know y, or kilometers, we can do x = 1,000y
