A bottle of water contains 450ml. How many litres of water are there in 8 of these bottles

Answers

Answer:

3.6 litres

Step-by-step explanation:

1 bottle = 450ml

8 bottles = 450 × 8

               = 3600ml

1000ml = 1 litre

3600ml = 3.6 litres (3600÷1000)

Answer:

3.6 litres

Step-by-step explanation:

1 bottle = 450ml

8 bottles = 450 × 8

              = 3600ml

1000ml = 1 litre

3600ml = 3.6 litres (3600÷1000)

Vanessa has scored 45, 32, and 37 on her three math quizzes. She will take one more quiz and she wants a quiz average of at least 40. What is the minimum score Vanessa needs to earn on her fourth quiz? Enter your answer in the box.

Answers

Vanessa needs at least a 46 on the 4th quiz.

What is an average?

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that Vanessa has scored 45, 32, and 37 on her three math quizzes. She will take one more quiz and she wants a quiz average of at least 40. The minimum score will be calculated as below:-

First, find the average of the three.

45 + 32 + 37 = 114

114÷3 = 38

4 total quizzes,  for a 40 average on 4 quizzes, she needs

40 x 4 = 160 total points

For 3 quizzes she has,

45 +32 +37 = 114 points

For the fourth quiz,

160-114 = 46

Therefore, Vanessa needs at least a 46 on the 4th quiz.

45 + 32 + 37 = 114

114÷3 = 38

4 total quizzes,


 for a 40 average on 4 quizzes she needs 40*4 = 160 total points




for 3 quizzes she has 45 +32 +37 = 114 points


160-114 = 46, she needs at least a 46 on the 4th quiz

Solve for all possible values of x. square root of the quantity x minus 9 end quantity plus 4 equals 8

a) x = −5
b) x = 7
c) x = 13
d)x = 25

Answers

Answer:

Option d)  x = 25

Step-by-step explanation:

we have

√(x-9)+4=8

Solve for x

Subtract 4 both sides

√(x-9)+4-4=8-4

√(x-9)=4

squared both sides

(x-9)=(+/-)4^2

(x-9)=(+/-)16

Adds 9 both sides

x=9(+/-)16

x1=9(+)16=25

x2=9(-)16=-7

Verify

1) For x=25

√(25-9)=4

√(16)=4

4=4 ----> is true

therefore

x=25 is a solution

2) For x=-7

√(-7-9)=4

√(-16)=4

The radicand cannot be a negative number

therefore

x=-7 is not a solution

Answers

(x + 3)/5 - (2x - 1)/3 = 4 / * 15

3(x + 3) - 5(2x - 1) = 15 * 4

3x + 9 - 10x + 5 = 60

7x = 60 - 9 - 5

7x = 46 / : 7

x = 6 4/7

Answer:

X= -46/7

Step-by-step explanation:

step1:  left part times 15 is   3(X+3)-5(2X-1)

step2: right part times 15 is 60

step3:   3(X+3)-5(2X-1)=60

step4:   3X+9-10X+5=60

step5:   -7X+14=60

step6:   -7X=46

step7:      X= -46/7
