How many zeroes are in the product of 40 × 10 7 ?
Answer:
Either, it's 2,800 and that would be 2 zeroes or it is 400,000,000 and that would be 8 zeroes
Step-by-step explanation:
40 x 10 x 7 = 2,800
40 x 10^6 = 400,000,000
Total 8 zeroes are in the product of 40 × 10⁷.
Let's step-by-step dissect the calculation and the total amount of zeros.
We are given the phrase 40 × 10⁷, where 10⁷ is defined as 10 multiplied by 7.
Step 1: Calculate 10⁷
10^7 means 10 raised to the power of 7, which is equal to 10,000,000 (10 million). This is because 10⁷ = 10 × 10 × 10 × 10 × 10 × 10 × 10 = 10,000,000.
Step 2: Calculate the product 40 × 10⁷
Now, we multiply 40 by 10,000,000:
40 × 10,000,000 = 400,000,000
The product 400,000,000 has a total of 9 digits.
Instead of just looking at the overall number of digits, we are more concerned with the amount of zeros in the product.
Counting the zeros:
In the number 400,000,000, there are 8 zeros. These zeros come from the seven factors of 10 in the product 10⁷.
So, the product of 40 × 10⁷ has 8 zeros.
In conclusion, the result of 40 times 10 raised to the power of 7 is 400,000,000, which has eight zeros. This is so because every factor of 10 adds a zero to the final total.

Simplification is to make something easier to do or understand and to make something less complicated.
Shantira is thinking of a number n.
Her first clue is that six less than six times her number is between twenty-four and forty-eight.
Let n be the integer number.
Then according to the condition,
Her first clue is that six less than six times her number is between twenty-four and forty-eight.
24 < 6n - 6 < 48
Add 6, then

Triangle A'B'C' is the result of dilation about the origin with a scale factor of 2 / 3 on triangle ABC. (Translation: Pippa was right)
How to determine the scale factor to modify a right triangle
Herein we find a picture a graph with two proportional right triangles, which means that the small triangle is the consequence of a rigid transformation. The kind of rigid transformation used is a dilation around the origin, whose formula is shown below:
P'(x, y) = k · P(x, y)
Where k is the scale factor.
There is a dilation if and only if each point is scaled by the same factor. If we know that A(x, y) = (3, 9), A'(x, y) = (2, 6), B(x, y) = (9, 9), B'(x, y) = (6, 6), C(x, y) = (3, 3) and C'(x, y) = (2, 2), then the scale factor for each point is:
Point A
(2, 2) = k · (3, 3)
k = 2 / 3
Point B
(6, 6) = k · (9, 9)
k = 2 / 3
Point C
(2, 2) = k · (3, 3)
k = 2 / 3
Then, triangle A'B'C' is the result of dilation about the origin with a scale factor of 2 / 3 on triangle ABC.

She pays for the fruit.
Work out how much money Sarah has left.
You must show all your working.
After spending the money on oranges and apple, Sarah is left with 20p.
What is defined as the cost of the product?In mathematics, a product is described as the result of multiplying two or several numbers together.Product cost makes reference to the expenses incurred in the production of a product.As per the given question;
Sarah spend the amount to buy the 3 oranges is 30p each.
Total spending on oranges = 3 x 30p = 90p.
For buying 1/2 kg of apple; Sarah spend the amount of £1.20 per kg.
Cost for half kg of apples = 60p.
Total cost = apple + oranges
Total cost = 60p + 30p = 90p.
Total cost = £1.50
Now, the only money Sarah has is one 50p coin and six 20p coins.
Sarah' money = 50p + (6 x 20)p
Sarah' money = 50p + £1.20
Sarah' money = £1.70
Money left = £1.70 - £1.50
Money left = £0.20 = 20p

What is Descriptive Statistics?Descriptive statistics, also known as brief informative coefficients, are used to summarize a specific data collection, which may be a sample of a population or a representation of the entire population. Descriptive statistics include measures of variability and central tendency (spread). Measures of central tendency include the mean, median, and mode, whereas measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
For instance, the sum of the following data set is 20: (2, 3, 4, 5, 6). A 4 (20/5) is the mean. A data set's mode is the number that appears most frequently, while its median is the value that is in the middle of the range of values. It is the value that separates a data set's higher values from lower values. There are many less common ways to use descriptive statistics, but they are nevertheless essential.

A Average speed distance of 60 km in 1 hr, 56km in 2hr ,70km in 3hr, 50km in 4hr,65km in 5 hr, 60 km in 6 hr = 14.61 km/hr

The average speed of a body is the mean value of its speed across time. The formula for average speed is required since the speed of a moving body is not constant and fluctuates over time. Even with changing speed, the values of total time and total distance traversed may be employed, and we can get a single number to describe the complete motion using the average speed calculation.
A body's average speed is equal to the overall distance traveled divided by the entire time spent. The average speed formula is as follows:
