The price of a ring was decreased by 25% to £390. What was the price before the decrease

1 answer:

7 0

You will pay $292.5 for a item with original price of $390 when discounted 25%. In this example, if you buy an item at $390 with 25% discount, you will pay 390 - 97.5 = 292.5 dollars

Reflect the triangle across the y-axis, and then translate the image 5 units down.

Ksju [112]

Step-by-step answer:

It is a glide reflection.

The order of sliding and reflection is not important if the gliding is parallel to the line of reflection, which is the case here.

So the equivalent is translate five units down, and then reflect over the y-axis.

Note in general that rotations will not be equivalent to an odd number of reflections. So looking for an equivalent, look for reflection.

Proportions, assist me please!

Anit [1.1K]

Step-by-step explanation:

$w = \frac{1}{2} {x}^{2} y \\ (2)w = \frac{1}{2} {x}^{2} y(2) \\ 2w = {x}^{2} y \\ \frac{2w}{ {x}^{2} } = \frac{{x}^{2} y}{ {x}^{2} } \\ \frac{2w}{ {x}^{2} } = y$

<h3>Answer:</h3>

$y = \frac{2x}{ {x}^{2} } \\$

3. Identify the subsets of real numbers that apply to /100/5

Alina [70]

Using number sets, it is found that the correct classification of the number is:

C. rational number, integer, whole number, natural number , real number.

Numbers are classified as:

Whole, which is all positive numbers and zero, also called natural.
Integers, which is the set of whole numbers plus negatives.
Rational, which is the set of integer numbers plus terminating or repeating decimals.
Irrational, which are non terminating decimals.
Real, which are the sum of rational and irrational.

In this problem, the number given is:

$\frac{100}{5} = 20$

Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.
