Sofia cuts a piece of felt in the shape of a kite for an art project. The top two sides measure 20 cm each and the bottom two si
Phantasy [73]

x + y  = 24       where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24. 
x^2 + z^2 = 13^2
y^2 + z^2  = 20^2            where z  = 0.5 * length of smaller diagonal)

form last 2 equations

y^2 - x^2  = 20^2 - 13^2  =  231
 now y = 24-x so we have

(24 - x)^2    - x^2 = 231

576 - 48x = 231

48x = 345

x =  7.1875

z^2  =  13^2 - 7.1875^2 =  117.34
z =  1.83

so smaller diagonal = 21.66 cm


looks like its the third choice.

Emil used 3/4 of a red bottle of paint and 1/5 of a blue bottle of paint in art class. how much paint did he use in all?
Dmitry [639]
First change the fraction to decimals or common denominators.
3/4 = 0.75 and 1/5 = 0.2
0.75 + 0.2 = 0.95 = 95/100 = 19/20

(3/4) = (15/20)
(1/5) = (4/20)
(15/20) + (4/20) = 19/20

Which is a simplified form of the expression -2b – 3(2b + 1)?
lakkis [162]

Answer:

C

Step-by-step explanation:

We need to use the distributive property to expand this.

The property is:

a(b+c) = ab + ac

So, the part " -3(2b+1) " will becomes:

-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3

So, the problem becomes:

-2b -3(2b+1) = -2b -6b -3

Now, we add like terms:

-2b - 6b - 3

(-2-6)b - 3

-8b - 3

This is the correct answer, answer choice C
