Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AC}{XZ}$ = $\frac{AB}{XY}$ , substitute values

$\frac{9}{XZ}$ = $\frac{4}{16}$ ( cross- multiply )

4XZ = 144 ( divide both sides by 4 )

XZ = 36 cm

-------------------------------------------------------

Also

$\frac{BC}{ZY}$ = $\frac{AB}{XY}$ , substitute values

$\frac{BC}{48}$ = $\frac{4}{16}$ ( cross- multiply )

16BC = 192 ( divide both sides by 16 )

BC = 12 cm

which property is illustrated by the following statement? 8+3.4=3.4+8? Associative Property of Addition, Inverse property of add

kykrilka [37]

Consider the given statement:

8+3.4=3.4+8

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Inverse property of addition: A number 'a' is said to have an inverse '-a' if $a+(-a)=0$ . This property is not used in the given statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ .

In the given statement, 8+3.4=3.4+8

which is expressed as 8+12 = 12+8, this statement holds commutative property of addition as whether 8 is added to 12 or 12 is added to 8, the result is same.

So, Commutative property of addition is illustrated in this statement.

A computer and printer cost a total of 1136

timofeeve [1]

Let's assign each a variable:

Computer: 3x
Printer: x

We know that the total is 1136, so:

x+3x=1136
4x=1136

Now, we divide 1136 by 4 to get the cost of the printer.

1136/4=284

So, now let's apply this to what we wrote previously.

Answer:

Printer: 284
Computer: 284*3= 852

The price of a house increases in value from £149,950 to £182,500

Rufina [12.5K]

Answer is 21.7%

Find difference in price:

182,500 - 149,950 = $32,550

Divide difference by original price:

32,550/149,950 x 100 = 21.71%
