product of the digits is 1/3 of the original number. Find this number
Answer:
15
Step-by-step explanation:
"There is a two-digit number such that the sum of its digits is 6"
The digits can be
0, 6 possible numbers: 06, 60
1, 5 possible numbers: 15, 51
2, 3 possible numbers: 23, 32
3, 3 possible numbers: 33
"the product of the digits is 1/3 of the original number"
That means we need a number that is 3 times the product of the digits.
0, 6 product of the digits: 0 3 times product: 0
1, 5 product of the digits: 5 3 times product: 15
2, 3 product of the digits: 6 3 times product: 18
3, 3 product of the digits: 9 3 times product: 27

If 2 lines intersect the system is called...
1. independent and inconsistent
2. dependent and consistent
3. independent and consistent
4. dependent and inconsistent
Answer:
3. independent and consistent
Step-by-step explanation:
Intersecting Lines have a single point at which the lines intersect. Therefore the solution to this type of system is called a consistent system. (A type of system of linear equation in two variables.) Therefore, there will be no point that is common to both lines. If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent. When you graph the equations, both equations represent the same line.
The maximum height reached by the barnacle is _______ m.
Answer:
1 answer is 1
2 answer is -1
3rd answer is 2pi
From the diagram, we can tell that the maximum height that is reached by the barnacle is 1m.
Why is this the maximum height?The Barnacle is going around the water level in the shape of a circle which the water level being the diameter.
This means that the maximum height the barnacle can reach is constricted by the radius such that it is the same as the radius of the circle. This means that the maximum height is 1m.

If we let x denote the length of the morning walk, Ahmed walks x + 2.5x or 3.5x miles each day. At the end of the week he has walked 7 times as far and he said that this was 30 miles.
Solve the equation to find out the distance of Ahmed’s morning walk x. Explain your reasoning and verify your answer.
Answer:
x = 1.2245
Step-by-step explanation:
Ahmed walks 3.5x miles each day.
Thus, at the end of a week (7 days), he would walk;
3.5x * 7 = 24.5x miles
But he said that his walk in a week = 30 miles. So that,
24.5x miles = 30 miles
24.5x = 30
x = [tex]\frac{30}{24.5}[/tex]
= 1 [tex]\frac{11}{49}[/tex]
x = 1.2245
To verify the answer,
24.5x = 24.5(1.2245)
= 30.00

Answer:
The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same
The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line
Step-by-step explanation:
The given linear equations are;
3·x - 6·y = 9...(1)
x - 2·y = 3...(2)
The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs
Making 'y' the subject of both equations gives;
For equation (1);
3·x - 6·y = 9
3·x - 9 = 6·y
y = x/2 - 3/2
For equation (2);
x - 2·y = 3
x - 3 = 2·y
y = x/2 - 3/2
We observe that the two equations are the same and will have an infinite number of solutions

a card board box has a mass of 1,800 g. When 4 books of equal mass are put into the box, the filled box has a mass of 9 kg. what is the mass of each book in grams
Answer:
You have an empty box which is 1,800 grams. After you put the books in, it's 9 kilograms. There are 9,000 grams in 9 kilograms, and 1,800 grams were already there before you put the books.. so just do 9,000 - 1,800 which equals 7,200. Then divide 7,200 by 4, because there are 4 books with equal mass.
Step-by-step explanation:
I divide 7200by 4 and I got 1800

Y=2write the equation of the line in slope intercept form
Answer:
y = 0x + 2
Step-by-step explanation:
y = 2 is the same as y = 0x + 2. The slope of this line is zero (0) (the line is horizontal).
In slope-intercept form, the equation of this line is y = 0x + 2, which may be left as is or changed to y = 2.

Find the approximate area of the lake whose shape is overlaid on the grid below. Each
square of the grid represents one square mile. (3 points)
Answer:
7.5 square miles
Step-by-step explanation:
Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.
Irregular Object
1 square = 1 sq. mile
Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.
(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5
The area of the lake is about 7.5 square miles.

Write an equation that represents the distance d and Miles traveled by the monarch butterfly and t days
Complete question :
When the monarch butterfly is migrating to the south, it has an average speed of 80 miles per day. Write an equation that shows the realtionship between the number of days (t) and the distance (in miles) it has traveled (d)
Answer:
d = 80t
Step-by-step explanation:
Given :
Average speed = 80 miles per hour
Distance traveled (in miles) = d
Number of days = t
Equation which shows the Relationship between Number of days and distance traveled :
Recall :
Speed = distance / time
Speed = 80 ; distance = d ; time = t
80 = d/t
80 * t = d
d = 80t
The random variable X~(30,2^2)
Find p(X<33)
Find p(X>26)
Answer:
i) P(X<33) = 0.9232
ii) P(X>26) = 0.001
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 30
Given that the standard deviation of the Population = 4
Let 'X' be the Normal distribution
Step(ii):-
i)
Given that the random variable X = 33
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-30}{2} = 1.5[/tex] >0
P(X<33) = P( Z<1.5)
= 1- P(Z>1.5)
= 1 - ( 0.5 - A(1.5))
= 0.5 + 0.4232
P(X<33) = 0.9232
Step(iii) :-
Given that the random variable X = 26
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-26}{2} = 3.5[/tex] >0
P(X>26) = P( Z>3.5)
= 0.5 - A(3.5)
= 0.5 - 0.4990
= 0.001
P(X>26) = 0.001

If a letter is randomly chosen, what is the probability of choosing the letter A?
Answer:
it depends on how many letters there are to choose from.
Answer:
if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%
Step-by-step explanation:
There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!
Or if you want to be really specific, 1/26 as a percent is 3.8462%.

Answer:
y = -5x + 65 or f(x) = -5x + 65
Step-by-step explanation:
The graph represents a linear function which means the function can be represented using y = xm + a, where y is the target, x is the domain, m is the slope, and a is the y-intercept.
According to the graph, the y-intercept is $65 which means a = 65
y = xm + 65
Since the x intercept is 13 that means when x = 13, then y = 0, plug those values in and solve for m to get the slope.
0 = 13m + 65
-65 = 13m
-65/13 = m
Which can be simplified to
-5 = m
Therefore the function for the graph is y = -5x + 65
