Asta needs a spanner for a 5-8 inch nut on her camping stove.
The shop sells 12mm spanners, 14mm spanners and 16mm spanners.
Asta knows that 1 inch = 2.54cm
What is the best size spanner for asta to buy?
Answers
After conversion, a 5-8 inch nut would require a spanner size between 127mm to 203.2mm. Unfortunately, the available spanner sizes (12mm, 14mm, 16mm) are all too small.
Explanation:To find out which spanner Asta needs, we first need to convert the inch measurements to millimeters (mm), as the spanners are sold in mm. Asta's nut size is 5-8 inches. She knows one inch equals 2.54cm. To convert these to mm, we multiply the values by 10 as 1cm is equal to 10mm. So, 5 inches equals 127mm and 8 inches equals 203.2mm. Given the available sizes of spanners (12mm, 14mm, and 16mm), none of these would fit her nut, as they are all far too small.

Using distributive law find the square of 101 and 72
Answers
To find the square of 101, we can use the distributive law as follows: 101^2 = (100 + 1)^2 = 10000 + 200 + 1 = 10201. Similarly, to find the square of 72: 72^2 = (70 + 2)^2 = 4900 + 280 + 4 = 5184.
Explanation:The use of the distributive law allows us to expand expressions by multiplying each term inside the parentheses by the term outside the parentheses. To find the square of 101, we can use the distributive law as follows:
101^2 = (100 + 1)^2 = 100^2 + 2(100)(1) + 1^2 = 10000 + 200 + 1 = 10201
Similarly, to find the square of 72:
72^2 = (70 + 2)^2 = 70^2 + 2(70)(2) + 2^2 = 4900 + 280 + 4 = 5184

All front and backyards in Alan's neighborhood are equal in size. Alan can mow his front and back lawns combined in about 45 minutes. If he is to mow both his front and backyard, along with the neighbor's front yard, how long will it take Alan?
Answers
Answer: 67.5 minutes
Step-by-step explanation:
Since the front and backyard are the same size, then Alan will take the same time mowing them. So, if he takes 45 minutes mowing both of them, that means that he took half the time mowing the front and the other half mowing the backyard.
[tex]\frac{45}{2} =22.5[/tex]
The neighbor's front yard is the same size as well, so it will take him the same time.
[tex]45+22.5=67.5[/tex]
Then, the total time that Alan takes mowing the three yards is 67.5 minutes.

A warden meets with 23 prisoners. He tells them the following:
Each prisoner will be placed into a room numbered 1-23. Each will be alone in the room, which will be soundproof, lightproof, etc. In other words, they will NOT be able to communicate with each other.
They will be allowed one planning session before they are taken to their rooms.
There is a special room, room 0. In this room are 2 switches, which can each be either UP or DOWN. They cannot be left in between, they are not linked in any way (so there are 4 possible states), and they are numbered 1 and 2. Their current positions are unknown.
One at a time, a prisoner will be brought into room 0. The prisoner MUST change one and only one switch. The prisoner is then returned to his cell.
At any time t, given some N>0, there exists a finite t_0 by which time every prisoner will have visited room 0 at least N times. (In other words, there is no fixed pattern to the order or frequency with which
prisoners visit room 0, but at any given time, every prisoner is guaranteed to visit room 0 again. If you’re still confused by this statement, ignore it, and you should be ok).
At any time, any prisoner may declare that all 23 of them have been in room 0. If right, the prisoners go free. If wrong, they are all executed.

Answers
To find the sum of the absolute deviations, calculate the average of the data set and then subtract it from each value, taking the absolute value. Finally, sum up all the absolute deviations.
Explanation:To find the sum of the absolute deviations, we first need to find the average of the data set. The average is calculated by adding up all the numbers and then dividing by the total number of values. So, the average of the data set 8, 5, 15, 12, 10 is (8 + 5 + 15 + 12 + 10) / 5 = 50 / 5 = 10.
Next, we calculate the absolute deviation for each number by subtracting the average from each value and taking the absolute value. The absolute deviations for the given data set are: |8 - 10| = 2, |5 - 10| = 5, |15 - 10| = 5, |12 - 10| = 2, |10 - 10| = 0.
Finally, we sum up all the absolute deviations: 2 + 5 + 5 + 2 + 0 = 14. Therefore, the sum of the absolute deviations is 14. So the correct choice is 14.

Two ships leave port at 10 A.M. One travels at a bearing of 50° at 25 mph, and the other travels at a bearing of 120° at 20 mph. How far apart are the ships at noon? Round your answer to the nearest tenth.
Answers
The second ship travels (20 mi/n)*(2 h) = 40 mi.
The angle between their directions of travel is 120° -50° = 70°.
The law of cosines can be used to find the distance (d) between the ships.
d² = 50² + 40² - 2*50*40*cos(70°)
d² = 2500 +1600 -4000*cos(70°)
d² ≈ 2731.919
d ≈ √2731.919 ≈ 52.3 . . . . miles
At noon, the ships are about 52.3 miles apart.

Brian makes 8% commission on sales. Weekly says total 4580, what is his Commission
Answers
To find Brian's commission, multiply his weekly sales of $4,580 by his commission rate of 8%. His commission for the week would be $366.40.
Explanation:To calculate Brian's commission, we need to apply the commission rate to his total weekly sales. Since his commission rate is 8%, we can calculate the commission by multiplying his total sales (
$4,580) by 0.08.
The calculation would be as follows:

Claire’s mother is 4 years more than twice Claire’s age. The sum of their ages is 58 years.
Answers
Claire’s mother is 4 years more than twice Claire’s age = 2x + 4
The sum of their ages is 58 years:
x + 2x + 4 = 58
3x + 4 = 58
3x = 54
x = 18
Claire's age = 18
Claire’s mother = 2(18)+4 = 36 + 4 = 40
claire's mothers age = 2x+4 ( 4 more than twice claire's age)
sum is addition
x + 2x+4 = 58
add like terms ( x +2x = 3x)
3x +4 = 58
subtract 4 from each side:
3x = 54
divide both sides by 3
x = 54 /3
x = 18
Claire is 18 years old
Claire's mother is 2*18 = 36 +4 = 40 years old

The length of each side of the equilateral triangle is approximately 52 cm.
Explanation:An equilateral triangle has all sides equal in length. To find the length of each side, we can use the property that an equilateral triangle's height is equal to half the length of one of its sides.
Since the height is given as 26 cm, we can set up the equation:
26 cm = (side length)/2
Multiplying both sides by 2, we get:
52 cm = side length
Therefore, the length of each side of the equilateral triangle is approximately 52 cm.

A 155 pound person burns about 500 calories per hour playing racquetball. one pound id equal to 3500.
Q- If the person were to rest 5 minutes for every 30 minutes of playing, how long would it take to burn 1 pound?
Answers
p= c/t

1 lb =3500 cal
500/1=c/5/12
c=208 cal
3500/t=208/(5/12)
3500/t=500
t= 7 min to burn 1 pound calorie
Answer:
[tex]8\frac{1}{6}[/tex] hours or 8 hours and 10 minutes.
Step-by-step explanation:
We have been given that a 155 pound person burns about 500 calories per hour playing racquetball. One pound is equal to 3500 calories.
Since the person burns 500 calories per hour, so time taken to burn 3500 calories would be:
[tex]\frac{3500\text{ cal}}{\frac{\text{500 cal}}{\text{Hour}}}[/tex]
[tex]\frac{3500\text{ cal}}{500}\times\frac{\text{Hour}}{\text{Cal}}=7\text{ Hour}[/tex]
Now, we will convert 7 hours to minutes.
1 hour equals 60 minutes.
7 hours = 7*60 minutes =420 minutes.
Since the person take a rest of 5 minutes for every 30 minutes of playing, so we will divide 420 by 30 to find the number of times the person rested to burn 3500 calories.
[tex]\frac{420}{30}=14[/tex]
Now, we will multiply 14 by 5 minutes to find minutes the person rested.
[tex]14\times 5\text{ minutes}=70\text{ minutes}[/tex]
Total number of minutes to burn 3500 calories: [tex]420\text{ minutes}+70\text{ minutes}=490\text{ minutes}[/tex]
[tex]\frac{490}{60}=\frac{49}{6}=8\frac{1}{6}[/tex]
Therefore, it will take 8 hours and 10 minutes to burn 1 pound.

Simplify the rational expression . x^2+9x+20/x+7The quotient is , and the remainder is .
Answers
We can conclude that the quotient of the division is (x+2) and the remainder is 6.
Final answer:
The rational expression x^2+9x+20/x+7 simplifies to (x+5) with a remainder of (x+4)/(x+7) after factoring the numerator.
Explanation:
To simplify the rational expression x^2+9x+20/x+7, you would factor the numerator and then divide the factors by the denominator if possible.
The factoring of x^2+9x+20 would yield (x+5)(x+4), as these are the factors of 20 that add to 9. Now the expression becomes:
((x+5)(x+4))/(x+7)
Since x+7 doesn't factor with either x+5 or x+4, the expression is already in its simplest form. So the quotient is x+5 with a remainder of (x+4)/(x+7).
Remember to check your answer to ensure it is reasonable.
