Paloma draws triangle ABC on a grid. She applies a rule to make the
triangle on the right. What rule did Paloma apply to make the new triangle?
===========================================
Explanation:
The image is not the same size as the preimage. This means a dilation has occurred. Specifically, the image has been shrunk. The scale factor k must be in the interval 0 < k < 1.
-----------
Point B is at (2,2)
It then moves to (1,1)
The scale factor is 1/2 = 0.5
To find the scale factor, you divide the image x coordinate over the preimage x coordinate.
So the triangle is now half as tall and wide compared to from before.
Point A is the center of dilation. The origin is often the default center. The center of dilation is the only point that doesn't move (fixed point).
Answer:
Dilation with scale factor 1/2 = 0.5
Step-by-step explanation:
The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?
5.2 ⋅ 107 kilometers
4.7 ⋅ 108 kilometers
5.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.

The number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.
What is the exponent power with base 10?To write the big number in short form, we write them in the positive power of 10.
To write the very small number, we write them in the negative power of 10.
Tyler’s math class found that it would take 2.5×10^8 dollar bills to cover a square mile area.
The surface area of the United States is about 3.8×10^6 square miles.
To find the number of dollar bills are needed to cover the United States, we have to multiply 3.8×10^6 square miles with 2.5×10^8 dollar bills.
Let suppose it needed n dollar bills. Thus,
[tex]n=3.8\times10^6\times2.5\times10^8\\n=3.8\times2.5\times10^6\times10^8[/tex]
When the base is same in multiplication operation, add the power. Thus,
[tex]n=3.8\times2.5\times10^6\times10^8\\n=3.8\times2.5\times10^{6+8}\\n=9.5\times10^{14}[/tex]
Thus, the number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

$ ___________
Answer: Simon paid $13.55 for the snack.
Plz mark brainliest ;)
Answer:
$13.55
Step-by-step explanation:
ok, so we know that Amber earned $15.50 on saturday and then he spet $6.95 on a movie ticket. so now we need to subtract $6.95 from his orgininal amount which was $15.50.
so $15.50 - $6.95 = $8.55
and then it says that he borrowed money from his friend to purchase a snack and that he now owes $5.00 to his friend so we add the amount of money he had plus the money he now owes his friend.
so $8.55 + $5.00 = $13.55
so in conclution, simon lent amber $5.00 and in total, they paid $13.55 for the snacks.
Hope that helps :)

Rewrite 2 4/7 as an improper fraction.
Answer:
[tex]\frac{18}{7}[/tex]
Step-by-step explanation:
[tex]2\frac{4}{7}[/tex]
→ Multiply 7 by 2 then add 4
7 × 2 = 14 + 4 = 18 ⇔ Numerator
7 ⇔ Denominator
Answer: 18/7
Explanation: To write a mixed number as an improper fraction, first multiply
the denominator times the whole number, then add the numerator.
So here, we multiply the denominator, 7, times the
whole number, 2, then we add the numerator, 4.
So we have (7 × 2) + 4 or 14 + 4 which is 18.
Finally, we put our new number over our
old denominator and we have our answer, 18/7.
So 2 and 4/7 can be rewritten as the improper fraction 18/7.
