Answer:
40
Step-by-step explanation:
The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.
The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt
What is scale factor?Scale factor is used to compare the size of two objects. Mathematically, we can write -
{K} = S{O1}/S{O2}
13 mg
Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt.
The mass of an average grain of rock sand is : 13 mg
The mass of an average grain of table salt is : 0.3 mg
So, we can write that -
{K} = M{rock sand}/M{table salt}
{K} = 13/0.3
{K} = 130/3
{K} = 43.4
So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.
Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Step-by-step explanation:
In a given year, the population of Metro City is 7420, and the population is decreasing by 152 people per year. The population of Smallville is consistently 1200 less than half of Metro City. Determine how long it will take for Smallville's population to reach 2282.
Which answer provides the correct equation and solution for the situation, where x represents the number of years?
A. The equation is 2282=2(7420−152x)+1200. It will take 45.26 years for the population of Smallville to be 2282 people.
B. The equation is 2282=2(7420−152x)+1200. It will take 45.26 months for the population of Smallville to be 2282 people.
C.The equation is 2282=12(7420−152x)−1200. It will take 3 months for the population of Smallville to be 2282 people.
D. The equation is 2282=12(7420−152x)−1200. It will take 3 years for the population of Smallville to be 2282 people.
Answer:
The correct option is D.
Step-by-step explanation:
Let x denote the years.
The information provided is:
The population of Metro City is 7420.The population is decreasing by 152 people per year.The population of Smallville is consistently 1200 less than half of Metro City.From the provided data derive the equation for the population of Smallville x years after as follows:
[tex]Y = [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
The population of Smallville is 2282 after x years.
Compute the value of x as follows:
[tex]2282= [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]
[tex]\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3[/tex]
Thus, the time it will take for Smallville's population to reach 2282 is 3 years.
The correct option is D.

Find the area of the shaded region
Answer:
35
Step-by-step explanation:
Here, the shaded region is equal to the non-shaded triangle. To know why this is, look at the formula for a triangle: A = b*h/2. But if we look further, we also know that the area of a rectangle is A = b*h. So the area of a rectangle is twice that of a triangle. And this is always true as long as the dimensions are the same. So here, the shaded region is just (14*5)/2 which is 35. We can also find this out by calculated the area of a rectangle and minus the area of the rectangle.

How long is 75% of a 24-hour day?
Answer:
18 hrs
Step-by-step explanation:
6hrs is 25%, so 6 times 3 is 18, Hope This Helps!
75% of a 24-hour day is 18 hour.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
75% of a 24-hour day
let 75% of 24 hour day be x.
So, 75% of 24 = x
x= 75/100 x 24
x= 3/ 4 x 24
x= 18 hours
Hence, 75% of a 24-hour day is 18 hour.

10•f(7)+9•g(-1)=
Answer:
-1
Step-by-step explanation:
By the rule of the functions, 10.[f(7)] + 9[g(-1)] = -1
From the graph attached,
Blue curve represents the function 'f' and the purple curve represents function 'g'.
We have to find the value of the expression with the help of the graph attached,
For a function y = f(x), (x, y) is a point on the curve representing the values on x-axis and y-axis respectively.
Given expression → 10[f(7)] + 9[g(-1)]
Since, y = f(x)
Therefore, for x = 7 y-value will be,
y = f(7) = -1
Similarly, y-value of the function 'g' at x = (-1) will be,
y = g(-1) = 1
By substituting these values in the expression,
10.[f(7)] + 9.[g(-1)] = 10(-1) + 9(1)
= 10(-1) + 9
= -10 + 9
= -1
Therefore, 10.[f(7)] + 9[g(-1)] = -1 will be the answer.

Answer:
6
Step-by-step explanation:
11 - -5 = 6
The temperature at noon is 6 degrees Celsius.
GivenSuppose it was -5 degrees Celsius at 6:00 a.m.
By noon, the temperature had increased by 11 degrees.
What is temperature?Temperature declines as altitude increases.
The temperature at noon is calculated by adding the morning temperature and temperature in the afternoon.
The temperature in noon = temperature at 6;00 a.m. + increase in temperature in afternoon.
The temperature in noon = -5 + 11
The temperature in noon = 6 degrees.
Hence, the temperature at noon is 6 degrees Celsius.
