"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

The only number that appears with both conditions is 15.

From the diagram, we can tell that the maximum height that is reached by the barnacle is 1m.

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.

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

The piece was 6 CM long because if its a 6 by 6 area it will make to a 36 square CM

Step-by-step explanation:

The length of piece of fabric is 6 cm.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, Karen was cutting out some fabric for a friend. She cut a piece that was 6 centimeters wide and had an area of 36 square cm.

Here, area of rectangular shaped fabric is Area =Length × Width

36=Length × 6

Length =6 cm

Therefore, the length of piece of fabric is 6 cm.

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.

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

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:

69 degrees

Step-by-step explanation:

1) Find x

The angles measured x degrees and (x-28) degrees have a sum of 180 degrees because straight lines always have a measure of 180 degrees. Knowing this, construct the equation:

[tex]x+x-28=180\\2x-28=180[/tex]

Add 28 to both sides

[tex]2x-28+28=180+28\\2x=208[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}= \frac{208}{2} \\x= 104[/tex]

Therefore, x is equal to 104 degrees.

2) Find the measure of the (x-28) degree angle

Plug x into x-28

[tex]x-28\\= 104-28\\= 76[/tex]

Therefore, the measure of this angle is 76 degrees.

3) Find y

All the interior angles in any triangle will add up to 180 degrees. Knowing this, we can construct another equation:

[tex](2y-1)+76+y= 180[/tex]

Open up the parentheses

[tex]2y-1+76+y= 180\\3y+75= 180[/tex]

Subtract both sides by 75

[tex]3y+75-75=180-75\\3y=105[/tex]

Divide both sides by 3

[tex]\frac{3y}{3}= \frac{105}{3} \\y=35[/tex]

Therefore, y is equal to 35 degrees.

4) Find the measure of the (2y-1) degree angle

Plug y into 2y-1

[tex]2y-1\\= 2(35)=1\\= 70-1\\= 69[/tex]

Therefore, y is equal to 69 degrees.

I hope this helps!

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

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

An airline food service finds that a recent flight of 120 passengers ordered dinner as depicted in the table to the right.

Here, Number of Lasagna for 120 passengers = 25

Hence, For 360 passengers number of lasagna is,

⇒ 120 / 35 = 360 / x

Where, x is umber of lasagna for 360 passengers

⇒ x = 360 × 25 / 120

⇒ x = 75

Thus, There are 75 lasagna dinners are likely to be needed for a flight with 360 passengers.
