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 needs at least a 46 on the 4th quiz.
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.
To know more about an average follow
#SPJ2
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
a) x = −5
b) x = 7
c) x = 13
d)x = 25
Answer:
Option d) x = 25
Step-by-step explanation:
we have
Solve for x
Subtract 4 both sides
squared both sides
Adds 9 both sides
Verify
1) For x=25
----> is true
therefore
x=25 is a solution
2) For x=-7
The radicand cannot be a negative number
therefore
x=-7 is not a solution
what is: x + 3 - 2x -1 = 4 5 3
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
