Savannah uses models to compare two decimal numbers. She says 0.35 is greater than 0.4 because 35 > 4.Which of these explains
Savannah's mistake?
Question 8 options:
Savannah incorrectly compared hundredths to tenths. She should compare 35 hundredths to 40 hundredths.
Savannah incorrectly compared tenths. She should compare 3 hundredths to 5 hundredths.
Savannah incorrectly shaded the models. She should shade one more tenth.
Savannah incorrectly counted the number of shaded parts in the models. She should compare 3 shaded parts to 4 shaded parts.

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:
Final speed of the skateboard(v) = 4 m/s
Answer:
The first set: 8, 15, and 17.
Step-by-step explanation:
<h3>Pair: 8, 15, 17</h3>By the pythagorean theorem, a triangle is a right triangle if and only if
.
In this case,
.
.
In other words, indeed . Hence, 8, 15, 17 does form a right triangle.
Similarly, check the other pairs. Keep in mind that the square of the longest side should be equal to the sum of the square of the two
<h3>Pair: 10, 15, 20</h3>Factor out the common factor to simplify the calculations.
.
.
Hence, by the pythagorean theorem, these three sides don't form a right triangle.
<h3>Pair: 12, 18, 22</h3>.
.
.
Hence, by the pythagorean theorem, these three sides don't form a right triangle.
<h3>Pair: 7, 9, 11</h3>.
.
Hence, by the pythagorean theorem, these three sides don't form a right triangle.
