Answers

Answer 1
Answer:

Answer: In decimal , it will be expressed as 0.6 .

Step-by-step explanation:

Since we have given that

Total number of students = 15

Number of students names as their favourite class = 9

First we write as a fraction, which is given by

(9)/(15)\n\n=(3)/(5)

Now , we will change it into decimal form using division, so it will be given by

0.6

Hence, our answer is 0.6.
Answer 2
Answer: 9/15  reduced to 3/5  which is 0.6

LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN = 5x + 19 and MP = 8x - 8
x=0

Answers

Question:

LMNP is a rectangle. Find the value of x and the length of each diagonal.

LN = 3x + 1 and MP = 8x – 4

Answer:

Value of x = 9, Length of LN = 64, Length of MP = 64

Solution:

Given LMNP is a rectangle. LN and MP are diagonals.

LN = 5x + 19 and MP = 8x – 8

Diagonals of a rectangle are equal in length.

⇒ LN = MP

⇒ 5x + 19 = 8x – 8

Combine like terms together.

⇒ 19 + 8 = 8x – 5x

⇒ 27 = 3x

Divide by 3 on both sides of the expression, we get

⇒ x = 9

The value of x is 9.

To find the length of the diagonals.

LN = 5(9) + 19

     = 45 + 19

LN = 64

MP = 8(9) – 8

     = 72 – 8

MP = 64

Length of LN = 64 and the length of MP = 64.

A stick is x meter long. A string is 4 times as long as the stick. Express the length of the stick in terms of x.

if Amanda walks an average speed of 2.72 miles per hour, how long will it take for her to walk 6.8 miles?

Answers

take 6.8 and divide by 2.72 and you get 2.5 hours

2.29 plus 4.75 plus 1.29

Answers

2.29 + 4.75 + 1.29 = 8.33
2.29 + 4.75 + 1.29 = 8.33

Eddie has saved up $45 to purchase a new camera from the local store. The sales tax in his county is 7% of the sticker price. Write an equation and solve it to determine the value of the highest priced camera Eddie can purchase with his $45, including the sales tax. Round your answer to the nearest penny.x − 0.07x = 45; $48.39
0.7x = 45; x = $64.29
7x = 45; x = $6.43
x + 0.07x = 45; x = $42.06

Answers

Let the price (before tax) be x. The tax is 7% of x, so it is 0.07x. The price plus the tax add up to $45. x + 0.07x = 45
