Tung rotates a square around its horizontal axis of symmetry to make a solid figure. What is the shape of the vertical cross sec

Iteru [2.4K]

The shape of the vertical cross section of the solid figure is Circle , Option A is the right answer.

What is a Circle ?

A circle is a round figure with all the points lying in the same plane .

It is given that

Tung rotates a square around its horizontal axis of symmetry to make a solid figure.

the shape of the vertical cross section of the solid figure will be a circle that can be seen in the image attached

The rotation image is also attached and the horizontal axis is taken as straight to show the formation of a circle.

Therefore Option A is the right answer.

I REALLY need help with these 3 questions plz!!!!

Answer:

6. No. See explanation below.

7. 18 months

8. 16

Step-by-step explanation:

6. To rewrite a sum of two numbers using the distributive property, the two numbers must have a common factor greater than 1.

Let's find the GCF of 85 and 99:

85 = 5 * 17

99 = 3^2 + 11

5, 3, 11, and 17 are prime numbers. 85 and 99 have no prime factors in common. The GCF of 85 and 99 is 1, so the distributive property cannot be used on the sum 85 + 99.

Answer: No because the GCF of 85 and 99 is 1.

We can solve this problem with the lest common multiple. We need to find a number of a month that is a multiple of both 6 and 9.

6 = 2 * 3

9 = 3^2

LCM = 2 * 3^2 = 2 * 9 = 18

Answer: 18 months

We can also answer this problem with a chart. We write the month number and whether they are home or on a trip. Then we look for the first month in which both are on a trip.

Month Charlie Dasha

1 home home

2 home home

3 home home

4 home home

5 home home

6 trip home

7 home home

8 home home

9 home trip

10 home home

11 home home

12 trip home

13 home home

14 home home

15 home home

16 home home

17 home home

18 trip trip

Answer: 18 months

First, we find the prime factorizations of 96 an 80.

96 = 2^5 * 3

80 = 2^4 *5

GCF = 2^4 = 16

Answer: 16
