The marks that have to be scored in 6th test to make the average 85 is 105 .
What is Average ?
Average of a data set is the ratio of sum of all the data to the number of data in the set.
It is given that the average score = 81
Total tests up till now = 5
Total tests overall = 6
New Average = 85
Let the sum of the score for 5 tests is x
Then by the formula of average
x / 5 = 81
x = 405
Now let the marks scored in the 6th test is y
then ( 405 +y) / 6 = 85
405 + y = 510
y = 105
Therefore , the marks that have to be scored in 6th test to make the average 85 is 105 .

Final answer:
A sailfish can swim a distance of 204 miles in 3 hours if it maintains its top speed of 68 miles per hour throughout.
Explanation:
In order to determine how far a sailfish can swim in 3 hours, we can use the speed given which is 68 miles per hour. This speed implies that the sailfish can swim 68 miles every one hour.
- First step is to recognize the information. We know that the speed of the sailfish is 68 miles per hour and we are asked to find the distance it can cover in 3 hours.
- Second step is to apply the formula for distance which is Speed times Time, in our case, 68 miles per hour times 3 hours.
- Last step is to multiply 68 by 3, giving us a product of 204.
Therefore, it's reasonable to estimate that a sailfish can cover 204 miles in a span of 3 hours, assuming it maintains its top speed the entire time.

Answer:
Step-by-step explanation:
number of likely voters = 2022
candidate A = 49%
candidate B = 46%
margin of error = 5%
using the concept of a confidence interval to explain
from the result of the poll conducted candidate A scored 49% of the votes while Candidate B scored 46% therefore the difference between the two voters is 3%.
also the margin of error is 5% which is higher than the 3% difference between the candidates. this margin error means that the 5% can vote for either candidate A or candidate B .which makes the results TOO CLOSE TO CALL

The volume of toy A will be equal to 13.7 cubic centimetres.
What are ratios and proportions?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio surface area of toy A: to the surface area of toy B is 7:9. The volume of toy B is 20 cm
The computation of the volume of toy A is shown below:
7 × k²=9
k²= 9 ÷ 7
k=√(9 ÷ 7)
k = 1.133893419
Now
The volume of toy A = 20 ÷ 1.133893419³
The volume of toy A = 13.7 cubic centimetres
Therefore, the volume of toy A will be equal to 13.7 cubic centimetres.
The missing figure is attached with the answer below.
