Hope this helps... Just comment me and say if im wrong or right
BTW I did the question on the calculator and got that answer
To add 7.14 x 10^10 and 3.15 x 10^10, sum the coefficients (7.14 + 3.15 equals 10.29) and keep the common exponent, resulting in the answer 10.29 x 10^10.
Explanation:The student's question involves the addition of two numbers that are written in scientific notation. This is a common operation in mathematics, specifically when dealing with very large or very small numbers. To add these numbers, we can simply add the coefficients (7.14 and 3.15) since the powers of 10 are the same (10^10 in both cases).
Here is the calculation step-by-step:
Add the coefficients: 7.14 + 3.15 = 10.29.Since the exponent part (10^10) is the same for both numbers, we keep it the same in the result.Combine the sum of the coefficients with the exponent part to get the final answer: 10.29 x 10^10.Therefore, the sum of 7.14 x 10^10 and 3.15 x 10^10 is 10.29 x 10^10.
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.

the graph shows the cost of traveling by car on a turnpike (graph shown in picture)
The slope of the line for the cost of traveling by car on a turnpike simplest form is -1.
How to calculate or determine the slope of a line?In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
By substituting the given data points (8, 0.60) and (32, 2.40) into the formula for the slope of a line, we have the following;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (2.40 - 0.60)/(32 - 8)
Slope (m) = 1.8/24

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.
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 diver is swimming at -10m. he then descends 3 m and rises 6 m. at what new level is the diver swimming?
Hey there!
The correct answer would be~
The diver is now swimming at -7 meters.
Here's how:
If the diver is already swimming at negative 10, going deeper would add to that.
(-10) + (-3) = -13
So at this point, he is at -13 meters. However, it says he rises 6 meters.
So if he rises, we need to subtract.
13 - 6 = 7
Therefore he is now at -7 meters.

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.

Justine wants to factor the expression 16a+40b by finding the GCF. How can you tell if she factors out the correct GCF
Final answer:
To factor the expression 16a+40b by finding the GCF, you determine that the GCF is 8 and then express the original terms as 8(2a + 5b). By distributing the GCF back into the factored terms and obtaining the original expression, you confirm the factorization is correct.
Explanation:
To factor the expression 16a+40b by finding the Greatest Common Factor (GCF), you first list the factors of each coefficient:
Factors of 16 are 1, 2, 4, 8, 16.
Factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40.
The GCF for these two numbers is 8 because it is the highest number that divides both 16 and 40 evenly. Now, you factor out the GCF from both terms in the expression:
8(2a + 5b)
To verify if the GCF is factored out correctly, you can distribute 8 back into the terms within the parentheses. If the original expression is obtained, the GCF was factored out correctly:
8*2a = 16a
8*5b = 40b
Therefore, the factored expression is correct, and Justine has successfully found and factored out the GCF.
