Which statement and explanation about the product of a 3-digit number and a 2-digit number is correct?
A. The product always has 4 digits. The least 3-digit number is 100, and the least 2-digit number is 10. The product of 100 and 10 has 4 digits, so any product of a 3-digit and a 2-digit number must have 4 digits.
B. The greatest number of digits in the product is 6. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 3 digits and 2 digits equals 6 digits, so no product of a 3-digit and a 2-digit number can have more digits.
C. The product always has 5 digits. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so any product of a 3-digit and a 2-digit number must have 5 digits.
D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.
The correct statement is :
D. The greatest number of digits in the product is 5. The greatest 3-digit number is 999, and the greatest 2-digit number is 99. The product of 999 and 99 has 5 digits, so no product of a 3-digit and a 2-digit number can have more digits.
The smallest 2 digits is 10, and the smallest 3 digits is 100
Their product is:
[tex]10 \times 100 = 1000[/tex] i.e. 4 digits
The greatest 2 digits is 99, and the greatest 3 digits is 999
Their product is:
[tex]99 \times 999 = 98901[/tex] i.e. 5 digits
This means that;
No product of the digits can have more than 5 digits
And, no product can have less than 4 digits
Hence, (d) is correct

Ten years from now Sam will be twice as old as she was three years ago.How old is she now?
Answer:
is ther any information about how old he will be in ten years from now
Step-by-step explanation:
g\
Sam's current age is 16 years old based on the provided condition.
Ten years from now, Sam will be twice as old as she was three years ago. Let's represent Sam's current age as x. According to the given condition:
Age after ten years = x + 10
Age three years ago = x - 3
Given that the age after ten years will be twice the age three years ago:
x + 10 = 2(x - 3)
Solving for x:
x + 10 = 2x - 6
x = 16
Therefore, Sam is currently 16 years old.

How to plot a graph?
A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
The point of intersection of the line and x-axis = (2,0)
The point of intersection of the line and y-axis = (0,3)
The slope of the graph or line
Slope = differcne in ys coordinate/difference in xs coordinate
Slope(m) = (3-0)/(0-2) = -3/2
Now equation of a line is given by
y = mx + c
Now keep point (2,0) and slope-3/2
0 = (-3/2)2 + c
c = 3
So, the equation would be
y = (-3/2)x + 3
Hence, The equation of the given graph will be y=-3/2x+3

Write the standard form of the line that contains a slope of -3/8 and passes through the point (5, -4). Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
Answer: [tex]3x+8y+17=0[/tex]
Step-by-step explanation:
We know that the equation of a line passing through a point (a,b) ans has slope 'm' is given by :-
[tex](y-b)=m(x-b)[/tex]
Given : Slope : [tex]m=\dfrac{-3}{8}[/tex]
Point = (5, -4)
Then, the equation of a line passing through a point (5, -4) ans has slope [tex]\dfrac{-3}{8}[/tex] is given by :-
[tex](y-(-4))=\dfrac{-3}{8}(x-5)\\\\\Rightarrow\ 8(y+4)=-3(x-5)\\\\\Rightarrow\ 8y+32=-3x+15\\\\\Rightarrow\ 3x+8y+32-15\\\\\Rightarrow\ 3x+8y+17=0\ \ [\text{In standard form}][/tex]
Therefore, the standard form of the line that contains a slope of [tex]\dfrac{-3}{8}[/tex] and passes through the point (5, -4):

A popular chain of superstore makes 30.479×10730.479×107 dollars in profit each year. One of its store makes 210.2×104210.2×104 in profit each year.
How many times greater is the profit made by the chain than by one of its store?
Enter your answer, using scientific notation, in the boxes.
Final answer:
To find how many times greater the chain's profit is than one store's, divide the chain's profit by the store's profit. After dividing the coefficients (30.479/210.2) and subtracting the exponents (7-4), we find that the chain's profit is 145 times greater than that of one store, which is 1.45 × 10² in scientific notation.
Explanation:
To determine how many times greater the profit made by the chain is than by one of its store, we need to divide the total profit of the chain by the profit of one store. Both profits are given in scientific notation as follows:
Chain's annual profit: 30.479 × 107 dollars
One store's annual profit: 210.2 × 104 dollars
To perform the division, we divide the coefficients and subtract the exponents:
(30.479 × 107) / (210.2 × 104) = (30.479 / 210.2) × 10(7 - 4)
Calculating the division of coefficients and exponents separately:
Coefficients: 30.479 / 210.2 ≈ 0.145
Exponents: 103, since 7 - 4 = 3
The result is:
0.145 × 103, which is the same as 1.45 × 102 in scientific notation after adjusting the decimal point one place to the right. Therefore, the chain's profit is 145 times greater than the profit of one store.
Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Final answer:
To find Seth and Eric's current ages, we can set up two equations using the given information and solve them simultaneously.
Explanation:
To solve this problem, let's start by assigning variables to the ages of Seth and Eric. Let Seth's age be represented by 'S' and Eric's age be represented by 'E'. We are given that currently Seth's age is 4/5 the age of Eric:
S = (4/5)E
We are also given that twenty-one years ago Eric was twice as old as Seth:
E - 21 = 2(S - 21)
Now we can solve these equations simultaneously to find their current ages. Let's substitute the value of S from the first equation into the second equation:
E - 21 = 2((4/5)E - 21)
Simplifying the equation, we get:
E - 21 = (8/5)E - 42
Moving all the terms with 'E' to one side, we get:
(8/5)E - E = 42 - 21
Simplifying further, we get:
(3/5)E = 21
To solve for E, we can multiply both sides of the equation by 5/3:
E = (5/3) * 21 = 35
Now that we know Eric's age, we can substitute this value back into the first equation to find Seth's age:
S = (4/5) * 35 = 28
Therefore, Eric is currently 35 years old and Seth is currently 28 years old.
