Step-by-step explanation:
1 pound is equivalent to 3500 calories.
if you burn 450 more calories per day, it will take as many days as the times 450 fits into 3500 :
3500 / 450 = 7.77777777... days
for 10 pounds we need to burn 10×3500 = 35000 calories.
35000 / 450 = 77.77777777... days (10 times more logically than for 1 pound).
3 x 1, 250 expanded form
The Expanded form of 3×1=3 is 3
The Expanded form of 250 is 200+50+0
Expanded form is nothing more than a method for rewriting a number such that the digit values are included. A place value exists for each number. It calculates that digit's value based on where it is in the number. As we move from left to right in a number, a digit's value rises. In comparison to the digits on the right, the ones on the left have a lower place value. The position of the number is used to calculate each number's value. We can comprehend the place value notations if we read them from right to left.
250=200(hundreds place)+50(tens place)+0(ones place)
Therefore, the Expanded form of 250 is 200+50+0.

Find the Least Common Denominator of 5/6 and 3/8, show all of your work:
To find the LCD of (5/6, 3/8) we need to find the Least Common Multiple (LCM), which in this case is (6, 8). So we want to find the values of the numerical part of each term. We need to select the largest one, which in this case is 8
Then multiply them together to get the current total. In this case, the current total is 48
Current Total = 48
Multiply the numeric part of the denominators together.
Current Total = 8 + 8 = 16
Again, multiply the numeric part of the denominators together.
Current Total = 16 + 8 = 24
Check each value in the numerical part of each term against the current total. Since the current total is evenly divisible, return it. That is the least common denominator of the numerical part of the fraction.
So the Lowest Common Denominator (LCD) is 24
In a genetics experiment on peas, one sample of offspring contained 383 green peas and 13 yellow peas. Based on
those results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the
value of 3/4 that was expected?
The probability of getting an offspring pea that is green is 0.967 and the value is not close to 3/4.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
In a genetics experiment on peas, one sample of offspring contained 383 green peas and 13 yellow peas.
The probability of getting an offspring pea that is green = 383/(383+13)
= 383/396
= 0.967
= 0.75
Thus, the probability of getting an offspring pea that is green is 0.967 and the value is not close to 3/4.

Write the statement "the sum of a number and 12.6 is more than −3.5" as an inequality.
−3.5 + b ≥ 12.6
−3.5 + b < 12.6
b + 12.6 > −3.5
b + 12.6 ≤ −3.5
Answer:
c
Step-by-step explanation:
For the given statement "the sum of a number and 12.6 is more than −3.5" the inequality is b + 12.6 > −3.5. Option C is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.For the inequality, we have to apply the arithmetic operation.
It is given that the sum of the number 12.6 is more than −3.5.
If the two numbers are b and 12.6 their sum is represented as b + 12.6 and the sum of the number is more than −3.5.
The obtained relation in form of inequality is,
b + 12.6 > −3.5
When we are unsure if the value of a variable is greater than a specific value, we use the "Greater than " symbol in linear inequalities. It is represented by the character ">"
Thus, for the given statement "the sum of a number and 12.6 is more than −3.5" the inequality is b + 12.6 > −3.5. Option C is correct.

In mathematics and statistics, the arithmetic mean or arithmetic average, or just the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection
An arithmetic average is the sum of a series of numbers divided by the count of that series of numbers. If you were asked to find the class (arithmetic) average of test scores, you would simply add up all the test scores of the students and then divide that sum by the number of students.
The arithmetic mean or mean is the simplest way to calculate the average for the given set of numbers. It is classified into two different types, namely simple arithmetic mean and weighted arithmetic mean.

what is 1150in hectares and in m2
Answer:
The answer is 11500000 Square Meters
Answer:
11,500,000
Step-by-step explanation:
To convert 1150 hectares to square meters, we need to multiply it by 10,000. Therefore, 1150 hectares is equal to 11,500,000 square meters. It is important to note that one hectare is equal to 10,000 square meters. So, 1150 hectares is equivalent to 11,500,000 square meters or 11,500,000 square meters. This conversion is useful when measuring large areas of land, such as agricultural fields, forests, and parks.

The manufacturing cost of a cell phone was $136. Sellers first marked up the cost by 25 percent. Sales were poor, so sellers decreased the markup to 17 percent. Calculate the old and new selling prices.
Answer:
old price was $170; new price is $159.12
Step-by-step explanation:
1) Formula given:
Selling price = original cost + mark up value
2) Old price = original cost + 25% (original cost)
Old price = $136 + 35% ($136) = $136 + 0.25×$136 = $136 + 34 = $170
3) New price = original cost + 17% (original cost)
= $136 + 17% ($136) = $136 + 0.17×$136 = $136 + $23.12 = $159.12
Answer:
old price was $170; new price is $159.12

She put 50 g of Substance A in the beaker labeled A and 50 g of Substance B in the beaker labeled B. The solution in both beakers was stirred for 1 minute. The amount of substance left undissolved in the beakers was weighed. The experiment was repeated for different temperatures of water and the observations were recorded as shown.

Part 2: Explain your answer for Part 1.
In the experiment, the solubility of B is high than the solubility of A.
This is because the mass of undissolved substance of substance A is more than Substance B at every temperature.
What is solubility?The amount of a substance that dissolves in a specific amount of solvent is known as its solubility. Higher solubility results from more solute dissolution, while lower solubility results from less solute dissolution.
Regarding the observations made, at any temperature, the mass of the undissolved material of substance A is greater than that of substance B. This suggests that less solute dissolves in the amount of solvent provided.
Therefore, because of this, substance B is more soluble than substance A.

8 times the sum of a number and 26 is less than 304.
Answer:
x < 12
Step-by-step explanation:
So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:
8(x+26) < 304
Lets start to solve for x by dividing by 8, giving us:
x+26 < 38
Now lets isolate x by subtracting 26 from both sides, which gives us our answer:
x < 12
So x is less than 12.
Hope this helps!
