Answers

Answer: B: 3/8 x 1/5

Step-by-step explanation:

It is B because when you are dividing fractions you do keep, change, flip.

1. 3/8 divided by 5

2. 3/8 divided by 5/1

3. Do KCF, 3/8 (keep) x (change) 1/5 (flip)

4. Equals 3/8 x 1/5

The division of the fraction number to the whole number will be (3 / 8) x (1 / 5). Then the correct option is B.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The fraction number is 3/8 and the whole number is 5. Then the division of the fraction number and the whole number is calculated as,

⇒ (3 / 8) ÷ (5 / 1)

⇒ (3 / 8) / (5 / 1)

⇒ (3 / 8) x (1 / 5)

The division of the fraction number to the whole number will be (3 / 8) x (1 / 5). Then the correct option is B.

Pentagon ABCDE is similar to pentagon RSTUV. The perimeter of pentagon ABCDE is 36.8 centimeters.

What is the length of ST ?
18 cm
25.8 cm
15 cm
19.8 cm

Answers

Answer:

15cm

Step-by-step explanation:

Since BC is like ST but smaller, we have to find the length of BC then find the proportion for ST.

Length of BC = 36.8 - 4.4 - 13.2 - 2.2 - 11

= 6

Scale = [tex]\frac{33}{13.2}[/tex]

Length of ST = [tex]\frac{33}{13.2}[/tex] × 6

= 15

The length ST of the pentagon RSTUV is 7.36 centimeters.

What is pentagon?

A polygon with 5 sides is a pentagon. The total sum of the internal angles of a pentagon is 540°.

Given is that Pentagon ABCDE is similar to pentagon RSTUV.

Since the pentagon ABCDE is similar to the pentagon RSTUV, we can conclude that the perimeter of the pentagon ABCDE is similar to that of pentagon RSTUV. Now, the sides of the pentagon are equal in length. So, we can write that -

ST = Perimeter/5

ST = 36.8/5

ST = 7.36

Therefore, the length ST of the pentagon RSTUV is 7.36 centimeters.
