PLS HELP
Answer: X = 17
Step-by-step explanation:
8.75 + 1.95x = 41.9
1.95x = 41.9 - 8.75

ara sells apples at a farmers market she begins the day with 35 1/2 pounds of apples she sells half of the apples in the mornning 4/19 of the apples in the afternoon and 1/4 of the apples in the evening how many pounds of apples dose she have left
Using mathematical operations, Ara's remaining pounds of apples are 1.405 pounds.
What are mathematical operations?The four basic mathematical operations are addition, subtraction, division, and multiplication.
In this situation, we applied the mathematical operations of multiplication, addition, and subtraction to determine the difference (or the quantity of apples left) between the quantity brought to the market and the quantity sold.
The total quantity of apples = 35¹/₂ pounds
The quantity sold in the morning = ¹/₂ of 35¹/₂ pounds = 17.75 pounds
The quantity sold in the afternoon = ⁴/₁₉ of 35¹/₂ pounds = 7.47 pounds
The quantity sold in the evening = ¹/₄ of 35¹/₂ pounds = 8.875 pounds
The total quantity sold = (¹/₂ + ⁴/₁₉ + ¹/₄) = ³⁶/₃₈ of 35¹/₂ pounds = 34.095 pounds
The remaining pounds of apples = 1.405 pounds (35.5 - 34.095)

There are 4 apples, 3 peaches and 2 plums in a grocery bag. If the the checkout person picks 2 plumbs and 1 peach out of the bag, what is the probability that the next piece of fruit out of the bag will be an apple?
According to the information, the probability that the next pice of fruit out of the bag will be an apple is 0.66.
How to calculate the probability that the next piece of fruit out of the bag will be an apple?To calculate the probability that the next piece of fruit out of the bag will be an apple we have to perform the following mathematical operation:
We have to calculate how many fruits there are in the bag.
4 apples, 3 peaches, and 2 plums less 2 plums and 1 peach = 4 apples, 2 peaches.So, we have 4 apples and 2 peaches, so we have 6 fruits in total. Now, we have to divide the number each fruit in the bag by the total number of fruits as shown.
4 / 6 = 0.66
2 / 6 = 0.33
According to the above, the probability that the next pice of fruit out of the bag will be an apple is 0.66.

When given a circle with a radius of 4, how do you find the following? explain why.
a. Diameter
b. Circumference
Answer:
Diameter is 8
Circumference is 8pi ~= 25.13
Step-by-step explanation:
The diameter is double the radius. So the given radius is 4 and double is 8.
The Circumference is given by C = pi•d or C = 2pi•r
Both of these equations will give the circumference.
C = pi•d
= pi•8
= 8pi ~= 25.13
OR
C = 2pi•r
= 2pi•4
= 8pi ~= 25.13
For finding the diameter, I multiply the radius by 2:
Diameter = 2 × radius
= 2 × 4
= 8
So the diameter is 8. As for the circumference, we can use two ways : either multiply pi times the diameter, or multiply 2 times pi times the radius.
The formulas are
C = πd and C = 2πr
To find the circumference, stick in 8 for d:
C = π × 8
C = 25.13 units

The range is not likely to vary, which is one of the claims regarding the new salary distribution that is supported.
What is standard deviation?Standard deviation is significant because it facilitates comprehension of measurements when data is scattered. The data's standard deviation will increase in proportion to how widely spread the data is. How dispersed the data is is indicated by the standard deviation. Any distribution will have roughly 95% of its values within two standard deviations of the mean. A large standard deviation doesn't necessarily mean something is wrong; rather, it only indicates that the group under study has a lot of variety, according to Rumsey in Statistics for Dummies.Therefore,
Given that a small company's salary distribution of 27 employees has a mean of $35,000 and a standard deviation of $2,000,
When a highly unusual value, such as 120000, is taken into account for the 28th employee, we discover that the mean increases.
The new median would be the average of items 14 and 15, as the prior median was the 14th item. Thus, the median may alter.
Because the maximum has been raised up to 120000, the range will undoubtedly vary.
so that we can say
Range changes, median changes, and mean increases.
Thus, we determine that Option B is correct.

The given triangle is obtuse triangle according to the corollary to the converse of the Pythagorean Theorem.
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The triangle's longest side measures 15 units in length.
Compare the sum of the squares on the other two sides to the square that is the length of the longest side.
The square of the longest side is 15², which equals 225.
9² + 10² = 181 square units make up the sum of the squares on the other two sides.
Thus, 181 < 15².

days. Then use the formula to find the amount of Iodine-125 that would remain in the tumor after 60
days.
Enter the exact answer.
Enclose arguments of functions in parentheses and include a multiplication sign between terms. For example, c*exp(h)
or c*ln(h)
.
Answer:
The exponential model representing the amount of Iodine-125 remaining in the tumor after t days would be:
Iodine-125(t) = 0.6 * e^(-0.0115t)
To find the amount of Iodine-125 that would remain in the tumor after 60 days, we would plug in t = 60 into the model:
Iodine-125(60) = 0.6 * e^(-0.0115(60))
= 0.6 * e^(-0.69)
= 0.6 * 0.5032
= 0.3019
So after 60 days, there would be approximately 0.3019 grams of Iodine-125 remaining in the tumor.

Kevin hiked up Lamb's Canyon in 3 hr and then ran back down in 2 hr. His speed running downhill was 1.8 mph greater than his speed hiking uphill. How far up the canyon did he hike?
Kevin hiked (blank) mi up the canyon.
Kevin hiked up Lamb's Canyon with the goal of making it to the top.
How far up the canyon did he hike?To solve it, you need to set up two equations - one for hiking and one for running.Let x be the distance Kevin hiked up the canyon.
For hiking: 3 hr = x / h
For running: 2 hr = (x + 1.8) / r
Where h is the speed at which Kevin hiked uphill and r is the speed at which he ran downhill.Solving the two equations for x yields:
x = (3h * r) / (h + r)
To find the distance Kevin hiked up the canyon, you need to plug in the values for h and r.Therefore, Kevin hiked (3h * r) / (h + r) mi up the canyon.
For the distance that Kevin hiked uphill, the equation would look like this:Distance = (x mph) * (3 hr)
For the distance that Kevin ran downhill, the equation would look like this:Distance = (x + 1.8 mph) * (2 hr)
We can combine these two equations by setting them equal to each other and solving for x. We get:(x mph) * (3 hr) = (x + 1.8 mph) * (2 hr)
Solving for x, we get x = 2.4 mph.
Now that we know x, we can plug it back into our original equation for the distance that Kevin hiked uphill. We get:Distance = (2.4 mph) * (3 hr) = 7.2 mi. Therefore, Kevin hiked 7.2 mi up the canyon.To learn more about to find the distance refer to:
