What is the Ratio of dimes to pennies

Answer:

Median is 17.5. Mean is 15.5

Step-by-step explanation:

Median is the middle number when ordered from smallest to largest. In this case 17 and 18 are the middle numbers so you split them. Median is the same as the average. Add all the numbers up ( They add to 124) and divide by the total number of responses (8 responses)

Answer:

A

Step-by-step explanation:

because 1 and 2 are the same

Answer:

Varied answer. Either 4.0225 km or 4.025 km

Step-by-step explanation:

Process 1: round 1.609 to 1.61, then multiply 1.61 by 2.5. This will give you 4.025 km. You might even go a step further and round it to 4.03 to put it in simplest form

Process 2: Leave 1.609 as is, multiply it by 2.5, giving you 4.0225 as an answer.

It all depends on how your teacher wants you to round to solve the equation.

Answer:

yes the answer is C ! none of the other answers are logical

Options :

A. 7x -(7x+20)=700

B.7x + 7(x+20) =700

C. 7x + (7x-20)=700

D.7x - 7(x-20) =700

Answer:

B.) 7x + 7(x+20) =700

Step-by-step explanation:

Given that :

Dave and Steven are 700m apart

They start walking towards each other and meet after 7 minutes

Distance covered by Dave per minute = x

Distance covered by Steven per minute = x + 20

rate = distance per minute

Dave's rate = x / minute

Steven's rate = (x + 20) / minute

Distance = rate * time

Distance covered by DAVE :

X /min * 7 = 7x

Distance covered by STEVEN :

(x + 20) * 7

= 7(x + 20)

Hence, the sum of distances covered by both Dave and Steven should add up to the total distance :

7x + 7(x + 20) = 700

  u = -45/7 = -6 3/7

Step-by-step explanation:

It can work well to eliminate fractions first. Here, we can do that by multiplying by the product of their denominators: 12.

Step-by-step explanation:

the cost of the t-shirts was $107.4  

Answer: $107.4

Answer: $107.40

Step-by-step explanation:

If you have 12 members that want to buy 1 shirt each then the they would be buying 12 shirts, that mean 12 of the $8.95 shirts.

$8.95 times 12 is $107.40

An easy way you can do that is by putting $8.95 times 10 which if something is times’d by 10 you just as a 0 to the end, ( if it’s a decimal you move the decimal back one) so then it’s $89.5, so now you’ve added 10, but you need to add 12, so you add 2 more $8.95 so $17.90 then add that to $89.5 which equals $107.40

Answer:

Susan has:

40 nickels & 10 dimes

Step-by-step explanation:

Since she has a total of 50 nickles and dimes I knew that it could be separated into 5 sets of 10. Knowing that 4(10) is equal to 40+10 is equal to 50, I used the 10 for the amount of dimes and used 40 for the amount of nickles. So the nickles (40) are 4 times the dimes (10). We can prove this by multiplying the dimes by 4 (4(10)) and you get 40 and add on the 10 you get the total amount of 50.

I hope this helps:)

There are 40 nickels and 10 Dimes.

Two or more expressions with an Equal sign is called as Equation.

Let N be the number of nickels

Let D be the number of dimes

Susan has a collection of 50 nickels and dimes.

N + D =50...(1)

Number of nickels is four times the number of dimes

N = 4D    

Substitute N in equation 1

4D+D=50

5D=50

Divide both sides by 5

D=10

Now put D value in equation 1

N+10=50

Subtract 10 from both sides

N=40  

Hence, there are 40 nickels and 10 Dimes.

Answer:

i. The description is sufficient to describe all cases of a circle.

ii. The description includes only necessary information to describe a circle.

iii. The description is a mathematically precise definition of a circle.

Step-by-step explanation:

A circle can be described as a plane shape bounded by circumference. It's circumference can be determined by: 2[tex]\pi[/tex]r, where r is its radius.

Thus, it can be said that it contains equidistant (equal distant) points from a common central point called the center of the circle. This definition can be used to describe any circle.

Some of its parts are: diameter, radius, sector, semicircle etc.

FV= $146,002.59

Step-by-step explanation:

Giving the following information:

Monthly deposit= $35

Number of periods= (65 - 23)*12= 504 months

Interest rate= 0.08/12= 0.0067

To calculate the future value, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

FV= {35*[(1.0067^504) - 1]} / 0.0067

FV= $146,002.59

Answer: Stratified Random Sample

Step-by-step explanation: The type of sampling exemplified by the manager's selection is Stratified Random Sampling whereby the entire population (guests in the hotel) are divided into subpopulation(independent subgroups) called strata; those with rooms facing the golf course and those facing the water view. The sample this have two strata based on the view in which the rooms are facing. Taking a simple random samples from each sub group of the entire population may lead to less bias since the customers may experience different level of satisfaction based on this condition.

The type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.

Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population.

Now here, the manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property.

So, here cluster sampling would be preferred because there are 30 floors and they can be classified as clusters and surveyed per floor.

Thus, the type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.

Answer:

3.41 m² of metal would be needed to cover the ramp

Step-by-step explanation:

The ramp has the shape of a triangular prism.

A triangular prism is a prism that has two equal triangles as base connected by three lateral faces.

The surface area of a triangular prism is the sum of the area of its base and lateral faces.

The surface area = 2B + PH

Where B is the area of the base , H is the height of the prism and P is the perimeter of the triangular base

Hence:

B = 0.5 * 1 m * 0.8 m = 0.4 m²

h = 1 m

P = 1 m + 0.8 m + 0.81 m = 2.61 m

Surface area = 2 * 0.4 m² + 2.61 m × 1 m = 3.41 m²

3.41 m² of metal would be needed to cover the ramp

4/7x - y = -17/7

Step-by-step explanation:

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

m = 4/7

Random point (1, 3)

Step 2: Find slope-intercept form

y = 4/7x + b

3 = 4/7(1) + b

3 = 4/7 + b

b = 17/7

y = 4/7x + 17/7

Step 3: Find Standard Form

-4/7x + y = 17/7

-(4/7x - y) = 17/7

4/7x - y = -17/7

Answer:

5.313mg

Step-by-step explanation:

The half-life of cesium-137 is 30 years. Suppose we have a 170-mg sample. What is the rate of decay after 150 years? (Round your answer to three decimal places.)

Half life formula

= N(t) = No(1/2)^t/t½

N(t) = Amount after t years

No = Initial amount

t = time

t½ = half life

N(t) = 170 (1/2) ^150/30

N(t) = 170 × (1/2)^5

N(t) = 5.3125mg

Approximately the quantity left after t years = 5.313mg

Answer:

11 feet

Step-by-step explanation:

It is found if originally the length was 7 ft, then it has to be 11 ft longer.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

We have given the initial dimensions are:

length: 7 feet

width: 6 feet

Therefore the area of the garden is given by:

Area = L x W

Area =  7 feet x 6 feet  = 42 square feet.

Since we need the area to be 108 square feet , then we can only change the length the width will still be 6ft.

We substitute the value of the new area and the width to the equation for the area as;

Area = L x W

108 = L x 6

L = 108/6

L = 18 feet

The length of the garden for the area to be 108 square feet, must be 18 ft.

This means that if originally the length was 7 ft, now it has to be 11 ft longer.

Answer:

x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

f(x) = 4x² - 12x + 9

To obtain the zero let f(x) = 0 , that is

4x² - 12x + 9 = 0 ← in standard form

(2x - 3)² = 0 ← in factored form , then

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

The zero of the function f (x) = 4x² - 12x + 9 will be 3/2.

What is Quadratic polynomial?

A polynomial which has highest power 2 is called a quadratic polynomial.

Given that;

The function is;

f (x) = 4x² - 12x + 9

Now, To find zero of the function we equate the function to zero.

We get;

f (x) = 4x² - 12x + 9

4x² - 12x + 9 = 0

Solve the function by quadratic formula we get;

x = - (-12) ± √12² - 4 × 4 × 9 / 2 × 4

x = 12 ± √144 - 144 / 8

x = 12 ± 0 / 8

x = 12/8

x = 3/2

Thus, The zero of the function f (x) = 4x² - 12x + 9 will be 3/2.
