It sounds like you are asked to estimate it. That's a very valuable skill.
9.634 is about 10
445.76 is about 446
So an approximate answer is 446 * 10 = 4460
How close is that to the actual answer? Let's find out.4294.45
On a test, if you get an answer like 4460 in your head, and your calculator says 4294.45, you are pretty certain that you have done the question correctly.
A consumer testing service is commissioned to rank the top 3 brands of laundry detergent. A total of 10 brands are to be included in the study. In how many ways can the consumer testing service arrive at the final ranking
Answer:
120ways
Step-by-step explanation:
This question bothers combination. Combination has to do with selection.
Given
Total number of brands = 10
If we the service is to rank the top 3, this can be done in 10C3 number of ways.
10C3 = 10!/(10-3)!3!
10C 3 = 10!/7!3!
10C3 = 10*9*8*7!/7!3!
10C3 = 10*9*8/6
10C3 = 720/6
10C3 = 120
Hence it will take 120ways for the consumer testing service to arrive at the final ranking

You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates that each crew will pour around 1200 yards per hour. How many consecutive days should you plan to work on this project?
Answer:
I believe it is 6 days.
The total number of days all crew needs to pour concrete is 6 days consecutive.
Work-day based problem:What information do we have?
Total number of crew = 3
Total yards = 175,000
Each crew pour concrete per hour = 1200
Total concrete pour per day = 1200 × 3 × 8
Total concrete pour per day = 28,800 yard
Total number of days crew pours concrete = Total yards / Total concrete pour per day
Total number of days crew pours concrete = 175,000 / 28,800
Total number of days crew pours concrete = 6.076
Total number of days crew pours concrete = 6 days

The price of a shirt is usually £45. During a sale the prices in the shop are reduced by 2 5 . How much is the shirt in the sale?
Answer:
£27
Step-by-step explanation:
From the above question, we know that:
The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .
Hence, the amount that the cost of tht shirt is reduced by is :
£45 × 2/5
= £18
The cost of this shirt in the sale is calculated as:
£45 - £18
= £27
What is the solution to the linear equation?
2/5+p=4/5+3/5p
Answer:
p=1
Step-by-step explanation:
Rearrange terms
Combine multiplied terms into a single fraction
Subtract 2/5 from both sides of the equation
Simplify
Multiply all terms by the same value to eliminate fraction denominators

44
-34
Answer:
44
Step-by-step explanation:
44÷5 is 8.8 which is greater than 7
Answer:
x=44
Step-by-step explanation:
Divide each number by 5
-44/5 = -8.8
34/5 = 6.8
44/5=8.8
-34/5=-6.8
8.8 is the only one greater than 7 so 44 is the only one that satisfies the inequality

Step-by-step explanation:
0.029 is 100 times smaller than 2.29 but 1979 is 100 times bigger than 19.79. The 100’s cancel each other out so the answer remains the same.

Find the measure of the exterior angle.
Answer:
108 degrees
Step-by-step explanation:
From the diagram we are given
Interior angles are 2x + 1 and 63 degrees
Exterior angle = 5x -2
The sum of interior angles is equal to the exterior angle
2x + 1 + 63 = 5x - 2
2x + 64 = 5x - 2
2x - 5x = -2-64
-3x = -66
x = -66/-3
x = 22
Get the exterior angle:
Exterior angle = 5x-2
Exterior angle = 5(22) - 2
Exterior angle = 110-2
Exterior angle = 108 degrees
Hence the measure of the exterior angle is 108 degrees

sin²x = 2-2cosX
Step-by-step explanation:
sin²x = 2 - 2cosx
1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)
cos²x - 2cosx + 1 = 0
(cosx - 1)² = 0
cosx - 1 = 0
cosx = 1
Hence x = 0.
