Step-by-step explanation:
The new price of the flash drive is not $10 because 20% of $10 is 2 and if 2 is marked down by 10% it would not be $10.
Answer: "Count 2 and then count 31 more."
Step-by-step explanation:
We have the equation:
231 - 198
Now, the negative number is kinda ugly, so i will write it as:
200 - 2 = 198
Is a lot easier work with 200 and 2, than with 198.
Then the equation is now:
231 - (200 - 2)
And the left number we also have a "200", so it can be written as:
200 + 31 = 231
As this is a sum, we can ignore the parentheses.
200 + 31 - 200 + 2
31 + 2
Then the correct option is:
"Count 2 and then count 31 more."
The two triangles are similar by SSA similarity. Option B is correct.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.
From the triangle ABC and DEC
The ratio of the sides is;

One angle c is common in the two triangles.
The two triangles are similar by SSA similarity.
Hence, option B is correct.

Answer:
300 cubic meters
Step-by-step explanation:
Volume of a Rectangular pyramid:
V = (lwh)/3
Given:
l = 10
w = 10
h = 9
Work:
V = (lwh)/3
V = (10 * 10 * 9)/3
V = 900/3
V = 300
If a field is 900 meters squared and one side is twice as big as the other how big is each side
