Answer:

No, it is not correct.

Step-by-step explanation:

Here, the given problem,

17 × 24

∵ 17 = 10 + 7

And, 24 = 20 + 4

Thus, 17 × 24 = (10 + 7)(20 + 4)

= 10 × 20 + 10 × 4 + 7 × 20 + 7 × 4

= 200 + 40 + 140 + 28

= 408

By comparing the above steps and Sebastian's model,

It is clear that he did incorrectly multiply 7 by 20,

i.e. he must write 140 instead of 40 while adding.

Sebastian's model is not correct because 20x7 does not equal 14.

Toni rides the Ferris wheel shown for 15 revolutions. A photo of a Ferris wheel has the diameter labeled fifty-six feet. Questio
NARA [144]

Answer:

a. 176 feet b. 2640 feet

Step-by-step explanation:

a. Since the diameter of the Ferris wheel is D = 56 feet, the distance Toni travels in one revolution is the circumference of the Ferris wheel, C = πD.

So C = 22/7 × 56 ft = 22 × 8 ft = 176 feet

b. The distance traveled in 15 revolutions is thus D' = 15 × distance of one revolution = 15 × 176 = 2640 feet

Start by converting 6% to a decimal by dividing by 100, = 0.06

Multiply that by the cost of the PlayStation five, and that is how much tax you pay.

499.99 x 0.06 = 29.9994

Miguel plots points A, B, and C in the coordinate plane.
serg [7]

Answer:

part a: 5

part b: no, ABC is not an equilateral triangle

Step-by-step explanation:

part a: if you do the distance formula for points A and B, you get 5

part b: using the distance formula again, points A to B and points A to C are both 5, but points B to C is 6, therefore it's not equilateral because all the sides have to be the same length
