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

20 points !!! -3/8x-20+2x>6
Semenov [28]

Answer:

x > 16

Step-by-step explanation:

- \frac{3}{8} x -20+2x>6

Add 20 to both sides:

-  \frac{3}{8} x + 2x > 26

Multiply 8 on both sides:

- 3x + 16x > 208

13x > 208

Divide by 13 on both sides:

x > 16

John uses 8/6 ounces of milk for his recipe . Mya uses 4/3 ounces of milk for her recipe. who uses more milk? explain your answe

To compare the fractions we need to find a common denomanator.
This means we need to find a common number (to the denomanator) in each number set of times tables.
In this case we can use 6 as a common denomator.

One of out fractions is already out of 6 so we just need to convert the other one. 
We can just double 4/3 to give us 8/6.
 
We can now compare the data, we have 8/6 and 8/6.
These fractions show that both John and Mya use the same amount of milk for their recipies, this being 8/6 or 1 1/3 as a mixed number.
