<h2>Answer:</h2>

The statement is a : False statement.

<h2>Step-by-step explanation:</h2>

Isometry--

An isometry is a transformation which preserve the length of a original figure.

The isometry consist of the transformations such as:

Reflection, Rotation, translation, glide etc.

Orientations means the ordering of letter around a figure.

We know that in transformation such as dilation, rotation the orientation is preserved whereas in reflection the orientation is reversed i.e. it is not preserved in reflection.

Hence, the correct answer is:

False.

Natasha_Volkova [10]

Answer: the credit union loaned out $40000 at 6% and $10000 at 12%

Step-by-step explanation:

Let x represent the amount that the

credit union loaned out at the annual rate of 6%.

Let y represent the amount that the

credit union loaned out at the annual rate of 12%.

credit union loaned out $50,000, part at an annual rate of 6% and the rest at an annual rate of 12%. It means that

x + y = 50000

The interest on $x after 1 year would be

6/100 × x = 0.06x

The interest on $y after 1 year would be

12/100 × y = 0.12y

The collected combined interest was $3,600 that year. It means that

0.06x + 0.12y = 3600- - - - - - - - - 1

Substituting x = 50000 - y into equation 1, it becomes

0.06(50000 - y) + 0.12y = 3600

3000 - 0.06y + 0.12y = 3600

- 0.06y + 0.12y = 3600 - 3000

0.06y = 600

y = 600/0.06

y = $10000

x = 50000 - y = 50000 - 10000

x = $40000

Explain how the Quotient of Powers was used to simplify this expression. 2 to the fifth power, over 8 = 22 By finding the quotie

astraxan [27]

Answer:

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.

Step-by-step explanation:

We have been given the expression $\frac{2^5}{8}=2^2$

8 can be rewritten as $2^3$

Hence, the given expression becomes

$\frac{2^5}{2^3}=2^2$

After subtracting the exponents on left hand side of the equation we get:

$2^2=2^2$

we can do it by simplifying 8 to $2^3$ to make both powers base two, and subtracting the exponents.
