Jack and his three siblings made a spinner to decide who has to do each chore. If there are three chores to do, what is the probability that Jack will have to do at least one of them? A. 37/64 B. 175/256 C. 7/8 D. 7/16
Answer:
7/8
Step-by-step explanation:
Because he has three brothers, and it also depends on how many times the spinner turns on each turn
The probability that Jack will have to do at least one chore is closest to B. 175/256 (approximately 0.683594). We calculated this by determining the probability of the opposite event (Jack doing none of the chores) and subtracting it from 1.
Explanation:The question is essentially asking: what is the probability that Jack will have to do at least one chore? When dealing with probabilities, it's often easier to calculate the chance of the opposite event and then subtract from 1.
In this scenario, the opposite event is Jack doing none of the chores. If there are 4 kids (including Jack), the probability of Jack not doing a specific task is 3 out of 4, or 0.75. Because there are three tasks, we multiply this probability three times (0.75*0.75*0.75), which equals 0.421875.
However, we want the probability that Jack will do at least one task, which is the opposite of him doing none. Therefore, we subtract this probability from 1: 1 - 0.421875 = 0.578125.
So, the closest answer to our result would be B. 175/256, which is approximately 0.683594, a little more than our calculated probability, but the closest among the given choices.

By which process are clouds dew and fog formed
Condensation. The water that evaporates into the sky gets condensed into clouds. For the dew,
"Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets."
Clouds, fog, and dew result from condensation, where cooling water vapor transforms into water droplets. Fog is a type of cloud at ground level, and dew forms on surfaces when the air cools down to the dew point. Clouds form aloft when droplets condense around microscopic particles in the air.
Explanation:Formation of Fog, Dew, and Clouds
The formation of fog, dew, and clouds is a result of the condensation process. When water vapor in the atmosphere cools, it changes into tiny droplets of liquid water. Clouds form when these droplets, which combine around condensation nuclei such as dust or pollen, group together aloft in the atmosphere.
Fog is essentially a type of cloud that forms near the ground level when the air temperature drops to the dew point where the air reaches saturation. Dew forms at the surface, typically during the night under cloudless skies and high humidity, when the surface cools enough to reduce the near surface air temperature to the dew point.
Frontal fogs occur due to a humidification process where warm, moist air over cooler, drier air at a weather front reach saturation and fog forms.

Pecan trees yield 45 pounds per acre and hazelnut trees yield 25 pounds per acre. Suppose Jenna’s farm has p acres of pecan trees, h acres of hazelnut trees, and yields 900 pounds of nuts. What is the equation that represents this scenario?
Answer:
Equation, 45 p + 25 q = 900
Explanation:
Pecan trees yield 45 pounds per acre and hazelnut trees yield 25 pounds per acre.
Pecan tree yield per acre = 45 pounds
Hazelnut tree yield per acre = 25 pounds
Acres of pecan trees in Jenna's farm = p
Acres of hazelnut trees in Jenna's farm = q
Total pounds of nut yielded = 900
So we have the equation,
45 p + 25 q = 900
Rachael has a rope 5 m 32 cm long that she cut into two pieces. One piece is 249 cm long. How many centimeters long is the other piece of rope?
1 m = 100 cm, so 5 m = 500 cm plus the 32 cm, so she has a rope that is 532 cm long.
532 - 249 = 283 cm
So the other piece of rope is 283 cm long.
The length of the other piece of rope is 283 cm after subtracting 249 cm (the length of the one cut piece) from 532 cm (the total length of the rope).
Explanation:The problem involves subtraction to find the length of the other piece of rope. Firstly, convert all measurements to the same unit for accuracy. Rachael's original rope length is 5 m 32 cm, which is the same as 532 cm (since 1 meter = 100 cm). The length of the one piece she cut off is 249 cm. To find the length of the other piece, subtract the length of the cut piece from the total length.
So, 532 cm - 249 cm = 283 cm.
Therefore, the other piece of rope is 283 cm long.

A triangular frame has sides that measure 15'-7",20'-4" and 26'-2". What is the total length of three sides?
we know that
[tex]1\ foot=12\ inches[/tex]
[tex]1'=12"[/tex]
Part 1)
we know that
side 1=15'-7"
side 2=20'-4"
side 3=26'-2"
To find the total length of three sides sum the three sides
so
total length=side 1+side 2 +side 3
substitute
total length=15'-7"+20'-4"+26'-2"
total length=(15'+20'+26')+(7"+4"+2")
total length=(61')+(13")
remember that
12"=1'
13"=12"+1"=1'+1"
substitute
total length=(61')+(1'+1")
total length=(62')+(1")---------> 62'-1"
therefore
the answer is
the total length of three sides is 62'-1"
To calculate the total length of the three sides of the triangular frame, add the lengths together. Convert inches to feet where necessary. The total length is 62'-1".
Explanation:The subject of this question is Mathematics, specifically basic addition within the context of geometry, specifically a triangular frame. To find the total length of the three sides of a triangular frame, we simply need to add the lengths of each side together. So, we add 15'-7", 20'-4", and 26'-2" together.
First, we tally the inches separate from the feet. Doing so, 7" + 4" + 2" gives us a total of 13". However, because there are 12" in a foot, we are left with 1", and 1' extra to add to our total feet.
The feet calculation then becomes 15' + 20' + 26' + 1' (from extra inches) which gives us a total of 62'. Therefore, the total length of the three sides of the triangular frame is 62'-1".

Final answer:
To convert 17 pounds to kilograms, multiply 17 by the conversion factor 0.45359237 to get 7.71107 kilograms. Considering significant figures and rounding to the tenths place, the final answer is 7.7 kilograms.
Explanation:
To convert 17 pounds to kilograms, we have to use the conversion factor between these units. A common conversion factor is that 1 pound is approximately equal to 0.45359237 kilograms. Therefore, to convert 17 pounds to kilograms:
Multiply 17 pounds by the conversion factor 0.45359237 kilograms per pound.
The result of the multiplication gives us the weight in kilograms.
17 pounds * 0.45359237 kilograms/pound = 7.71107 kilograms. However, we need to consider significant figures and round our answer appropriately.
Next, we identify the least precise measurement: 13.7 kg. This measurement is expressed to the 0.1 decimal place, so our final answer must also be expressed to the 0.1 decimal place. Thus, the answer should be rounded to the tenths place, giving 7.7 kg as the converted mass.

Cherries cost 4 dollars per pound. Mother bought r lbs and father bought 2 lbs. How much more money did mother spend on cherries than father?
Answer:
4r-8
Step-by-step explanation:
First mother buys r lbs and that means it's 4*r and you simplify that to 4r. So you have that much money right now. You have to subtract 2*4 which can be simplified to 8. That's how you get 4r-8
(4r - 8) dollars more money mother spend on cherries than father.
What is a numerical expression ?A numerical expression is written in form of numbers and their operations.
According to the given question Cherries cost 4 dollars per pound.
Mother bought r lbs.
∴ Cost of the cherries are weight times dollars per pound which is = 4r.
Father bought 2 lbs so the cost of the cherries are = 4(2) = 8 dollars.

Step-by-step explanation:
square root of 5 = 2.2360679775
This number is between 2 and 3
(I hope this was the correct answer to the question asked )
The square root of 5, while not a whole number, lies between the integers 2 and 3 as it represents a value between 2 squared (4) and 3 squared (9).
Explanation:The square root of 5 is indeed between two integers. To understand this concept, it's important to grasp what square roots represent. If a number is squared, like 2², it becomes 4. So, the 'square root' of 4 would be 2, the number that was initially squared. In the case of the number 5, there's no integer that can be squared to result in exactly 5. However, it is known that 2²=4 and 3²=9. Therefore, the square root of 5, being between 4 and 9, must lie between the integers 2 and 3. This is why we can confidently say that the square root of 5 is between the integers 2 and 3.

carol has only 20p and 10p coins in her purse
she has three times as many 20p coins and 10p coins
if Carol has £4.20 altogether, how many 20p coins does she have
Carol has 18 20p coins in her purse, determined by creating and solving an equation based on the coin values and the total amount of £4.20.
The question requires us to figure out how many 20p coins Carol has if she has three times as many 20p coins as 10p coins and the total amount is £4.20. To solve this, let's let the number of 10p coins be x and the number of 20p coins be 3x since she has three times as many 20p coins.
Now, we can create an equation based on the value of the coins. Each 10p coin is worth 0.10 pounds and each 20p coin is worth 0.20 pounds. The total value can be represented by this equation: (0.10x) + (0.20 * 3x) = 4.20.
Simplifying this, we get 0.10x + 0.60x = 4.20, which adds up to 0.70x = 4.20. Dividing both sides by 0.70 to solve for x, we have x = 6. Since x represents the number of 10p coins, and there are three times as many 20p coins, we multiply 6 by 3 to find the number of 20p coins, which is 18.
Therefore, Carol has 18 20p coins.

Pizza Palace cuts a medium pizza into 8 slices. The same size pizza at Pizza Pioneers is cut into 16 slices. Jasmine ate 4 slices of a medium pizza from Pizza Pioneers. What fraction of the pizza from Pizza Palace is equal to 4/16? Explain.
Jasmine ate an equivalent of 1/4 of a Pizza Palace pizza when she had 4 out of 16 slices from a Pizza Pioneers pizza, which is the same as 2 out of 8 slices.
Explanation:Jasmine ate 4 slices of a medium pizza from Pizza Pioneers, which was cut into 16 slices. To find out what fraction of a Pizza Palace pizza (which is divided into 8 slices) she ate, we compare the fractions. The fraction 4/16 can be simplified to 1/4 by dividing both the numerator and the denominator by 4. Therefore, Jasmine ate the equivalent to 2 slices of a Pizza Palace pizza since 1/4 of the Pizza Palace pizza is 2 out of 8 slices (2/8 which also simplifies to 1/4).
Final answer:
Jasmine's 4 out of 16 slices from Pizza Pioneers is equal to 1/4 of a pizza. When converting this to Pizza Palace's 8-slice pizza, it is equivalent to 4 out of 8 slices, or 1/2 of their pizza.
Explanation:
When dealing with fractions of pizzas, we're exploring the concept of equivalence. In the scenario where Pizza Palace cuts their medium pizza into 8 slices, and Pizza Pioneers cuts the same size pizza into 16 slices, we're comparing two different fraction denominators for the same whole.
Jasmine ate 4 slices out of 16 at Pizza Pioneers. This is 4/16 of a pizza, which simplifies to 1/4 when divided by 4 (both numerator and denominator). Now, since Pizza Palace cuts their pizza into 8 slices, to find the equivalent fraction, we need to determine what fraction 1/4 is when the pizza is instead cut into 8 pieces.
To do so, we realize that half of Pizza Palace's pizza (which is cut into 4 slices) is the same as 1/4 of the pizza from Pizza Pioneers. Therefore, 4 out of 8 slices at Pizza Palace would equal the 4 out of 16 slices Jasmine ate at Pizza Pioneers.
