The dilation scale factor is applied to all lengths.
... A'B' = (10 in)×25 = 250 in.
Answer:
5
Step-by-step explanation:
44.75 - 28.50 = 16.25 so 16.25 divided by 3.25 equals 5 and 5 times 3.25 equals 16.25 and 16.25 plus 28.50 equals 44.75 so she bought 5 cards.
The correct answer is Option A , D , E.
<h3>
What is meant by ratio?</h3>
A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other.
<h3>
What is meant by ratio in simplest form?</h3>
Ratio in it's simplest form means when the ratio can't be simplified anymore by cancelling out the common factors.
The ratio in Option(A) can't be simplified anymore because 29 is a prime number.
The ratio in Option(B) can be simplified to 1 / 7.
The ratio in Option(C) can be simplified to 5 / 2.
The ratio in Option(D) can't be simplified.
The ratio in Option(E) can't be simplified because 19 is prime number.
Hence, the correct answer is Option A , D , E.

Answer: 16
Step-by-step explanation: When you have a set of parentheses in an order of operations problem, you must simplify what's inside that set of parentheses first before you do anything else.
So our first step here is to subtract 6 - 8 which gives us -2.
So in our next step we have 3 (-2)² + 8 ÷ 2.
Now remember to do exponents before you multiply.
So (-2)² is just -2 × -2 or 4.
So in our next step we have 3 x 4 + 8 ÷ 2.
Now, we multiply so we have 3 x 4 which is 12.
So we have 12 + 8 ÷ 2.
Now we can divide.
8 ÷ 2 is 4 so we have 12 + 4 or 16.
So the answer to this problem is 16.
X intercept: when y = 0
y intercept: when x = 0
Plug info inside the equation
3x + 7(0) = 42
3x = 42, x = 14
Therefore, x intercept: (14,0)
3(0) + 7y = 42
7y = 42, y = 6
Therefore, y intercept: (0,6)
