Urvi solved a fraction division problem using the rule “multiply by the reciprocal.” Her work is shown below.

5×4 is 20. So I figure 9×4 is 36. 36 minutea

Answer: 20 minutes

Step-by-step explanation:

Imagine that each person is assigned one wall, and all 5 people begin painting at the same time.

Since everyone will finish painting their assigned wall after 20 minutes, it takes one person 20 minutes to paint one wall.

If we have 9 people and 9 walls, we can again assign one wall to each person.

Everyone will take 20 minutes to paint their assigned wall.

In other words, it takes 20 minutes for 9 people to paint 9 walls.

Answer:

m = 1/3

Step-by-step explanation:

The equation of a straight line is given by the equation of the form;

y = mx+c

The slope of the line is simply the coefficient of x in the equation, m in this case. The given equation can be re-written as;

y = 1/3 x + 4

The coefficient of x is 1/3 which is also the slope.

Answer:

Period, but I have to add more characters so it'll let me post this answer.

Period gives the horizontal length of one cycle of a periodic function as 2π.

Given that,
To determine which term gives the horizontal length of one cycle of a periodic function.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
In the periodic function 1 period is consist of 2π on the horizontal axis, so, the period represents the horizontal length of the periodic function.

Thus, Period gives the horizontal length of one cycle of a periodic function as 2π.

Answer:

Look for where both functions have the same y value. For example, when x = 3 in #7, both are 5. So the solution is (3,5).

Step-by-step explanation:

Each table has two functions. This forms a system of equations. A system of equations is essentially two conditions that must both be met to produce a solution. A solution can be found as where the two equations are equal. In the table, look for where both functions have the same y value for some x. This will be where the values are the same in the same row. This is the solution and is written as an (x,y) point.

7. When x = 3 both functions are 5. The solution is (3,5).

The correct option is B.

The exact circumference of a circle with radius X/2 miles is Xπ miles.

To find the circumference of a circle, we use the formula: Circumference (C) = 2πr, where r is the radius of the circle. Given that the radius is X/2 miles, we substitute this value into the formula:

C = 2π × (X/2)

  = Xπ miles

Therefore, the exact circumference of the circle with radius X/2 miles is Xπ miles.

The correct answer is B) xπ miles.

In summary, to find the circumference, we simply multiply the radius (X/2) by 2π, which gives us Xπ miles. This answer aligns with option B) xπ miles.

Tim is 9 years old, and Amy is 18 years old. We found this by dividing 54 by 6 and 3 respectively, based on the given equations 6T = 54 and 3A = 54.

To solve the problem involving Tim and his sister Amy's ages, we need to set up equations based on the information given. The problem states that six times Tim's age is 54 and that three times Amy's age is also 54.

Let's let T represent Tim's age and A represent Amy's age. We can set up the following two equations based on the problem:

To find Tim's age, we divide both sides of the first equation by 6:

T = 54 / 6

T = 9

So, Tim is 9 years old.

To find Amy's age, we divide both sides of the second equation by 3:

A = 54 / 3

A = 18

So, Amy is 18 years old.

Answer:

y = 5x

Step-by-step explanation:

20 = 5(4)

20 = 20

Since they directly vary, this is a linear equation, and the slope is 5.

y = mx + b

y = 5x + b

20 = 20 + b

b = 0

So the equation is

y = 5x

Answer:

for 5 hours: b is 6

for 5 minutes: b is 4

60 times more skin in 5 hours than 5 minutes

Step-by-step explanation:

I think it should be written as a x 10^b, so I'm going to answer it that way.  

3 x 10^6 = 5 times 10^6

   10^6 = 1,000,000, so we have 3 x 1,000,000 = 3,000, 000

5 x 10^4 = 5 times 10^4

   10^4 = 10,000, so we have 5 x 10,000 = 50, 000

For part 3, divide 3 million by 50 thousand to find the scalar multiple

   3,000,000/50,000 = 300/5 = 60

Answer:

The approximate number of particles of skin a human can shed in five hours can be written in the form a × 10b, where a is 3 and b is 6.

The approximate number of particles of skin a human can shed in five minutes can be written in the form a × 10b, where a is 5 and b is 4.

Humans shed approximately 60 times more particles of skin in five hours than in five minutes.

Step-by-step explanation:

In scientific notation, a number can be written in the form, a × 10b, where a is a number that must be greater than or equal to 1, but less than 10, and b is any integer.

First, write the approximate number of particles of skin a human can shed in five hours in scientific notation. This number is three million which can be written in the form a × 10b, where a is 3 and b is 6.

Next, write the approximate number of particles of skin a human can shed in five minutes in scientific notation. This number is fifty thousand which can be written in the form a × 10b, where a is 5 and b is 4.

Then, divide the approximate number of particles a human can shed in five hours by the approximate number of particles a human can shed in five minutes to find out how many times more skin is shed in five hours than in 5 minutes.

Therefore, humans shed approximately 60 times more particles of skin in five hours than in five minutes.

The scale factor is 1/3

The correct answer is 1/3

:))

The scale factor of the given dilation is 1/3

To change the size of a figure without changing the figure's shape, we use a exact number or factor which is called scale factor.

Dilated figure = Original figure × Scale factor

In the diagram,

Co-ordinate of the point V in original triangle is (3, - 6)

Co-ordinate of the point V' in dilated triangle is (1, -2)

We know that, if we multiply scale factor to the original co-ordinate then we get dilated co-ordinate.

Here, if we multiply 1/3 to the original co-ordinate V(3, - 6) then we get the dilated co-ordinate V' (3/3, -6/3) , i.e. V'(1, -2)

So, the scale factor is 1/3.

Answer:

(1, 5)

Step-by-step explanation:

You need a point in the shaded region that is not on the line of the graph.

The points can't be on the line because the line is a dotted line, which means there is either a < or > sign in the inequality, so the solutions are strictly less than or greater than the values on the line.

 Points A and B are on line so they aren't solutions.

Point (5, -5) is below the line, so that isn't a solution for this equation either

Point (1, 5) is in the shaded region, so it's a solution

Answer: 15 Inches

Step-by-step explanation:Remember that the Perimeter of a rectangle is the distance around it.

So,

    Perimeter = Length + Width + Length + Width

or

     P = 2L + 2W

If P=42 inches and W = 6 inches,

    42 = 2L + 2(6)

    42 = 2L + 12

    30 = 2L              [subtract 12 from both sides]

    15 = L               [divide both sides by 2]

The length (L) is 15 inches.

The length (L) is 15 inches. so the correct option is B.

Its the sum of length of the sides used to made the given figure.

It is given that the Perimeter of a rectangle is the distance around it.

Given that the perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches then we need to find the length.

So,

The Perimeter = Length + Width + Length + Width

Let the length of the rectangle = l

the width of the rectangle = w

or P = 2L + 2W

If P=42 inches and W = 6 inches,

42 = 2L + 2(6)

42 = 2L + 12

30 = 2L            

L = 15

Hence, The length (L) is 15 inches.

Step-by-step explanation:

Coterminal means it is in the same place on the Unit Circle but with one or more rotations clockwise or counterclockwise.

Note: one rotation is 360°

-760 + 360 = -400

                     -400 + 360 = -40
