Answer 1

Answer:

Step-by-step explanation:

Each game costs 2 dollars, so that total spent on games will be 2 * x. We have to add the one time payment of $3, so this will be (2 * x) + 3. Finally, she spends a total of $17, so the final equation will be (2 * x) + 3 = 17.

"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?

Answers

Answer:

10x

Step-by-step explanation:

Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF

First let us find the factors of each terms

60x³ = 6 * (10 * x) * x²

10x² = 1 * (10 * x) * x

30x = 3 * (10 * x)

From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

Find the simple interest. Round to the nearest
cent if necessary.
$1450, 32%, 3 months

Answers

Answer: $116

Step-by-step explanation:

Simple interest is calculated using the formula = PRT

where,

P = principal = $1450

R = rate = 32%

T = time = 3 months = 3/12 = 1/4 = 0.25

Interest = PRT

= 1450 × 32% × 0.25

= 1450 × 0.32 × 0.25

= $116

The simple interest is $116

Twice the sum of a number and -6 equals -6 times the sum of the number and 4. Let n stand for the number. Solve for n.

Answers

Answer:

n = -18/7

Step-by-step explanation:

Represent the number with n.

Then:

n - 6 = -6(n + 4)

Performing the indicated multiplication, we get:

n - 6 = -6n - 24

Combining like terms results in 7n = -18, so n = -18/7

the difference of two number is 28 if the larger number is three time of the smaller find the number​

Answers

Set up an equation:

3x - x = 28

Simplify:

2x = 28

Divide both sides by 2

X = 14

3(14) = 42

The numbers are 42 and 14

Step-by-step explanation:

like terms have the same variables  but don't need to have the same coefficients.

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

Someone plz help me >_<​

Answers

Answer: (x - 2) ^2 + (y - 6) ^2 = 25

Answer:

(x - 48)² + (y - 24)² = 64

Step-by-step explanation:

From the graph we see that

The diameter of the circle is: d = 16 mmThen its radius is: r = 16 mm/ 2 = 8 mmThe center has x-coordinate: h = 40 + 8 = 48Y-coordinate: k = 32 - 8 = 24

Use circle formula:

(x - h)² + (y - k)² = r²

Substitute values to get required equation:

(x - 48)² + (y - 24)² = 8²(x - 48)² + (y - 24)² = 64

The number of households without a computer at home in 2009 was closest to A)801000 B)1153000 C)1737000 D)3433000 E)4017000

Answers

Answer:

B) 1153000

Step-by-step explanation:

Given

See attachment

Required

Number of households without computer in 2009

From the attachment, we have:

[tex]n=5170000[/tex] --- survey

[tex]p = 22.3\%[/tex] --- proportion without computer

So, the actual number is:

[tex]Number = p * n[/tex]

[tex]Number = 22.3\% * 5170000[/tex]

[tex]Number = 1152910[/tex]

[tex]Number \approx 1153000[/tex]

Hence: (B) is correct

find the median and mean 42,15,14,48,39​

Answers

Answer:

Hello! the answer is 39 and 32

Step-by-step explanation:

To find the median we need to reorder the numbers from lowest to highest:

14,15,39,42,48

The one in the middle is the median! If there happens to be an even number, take the two middle numbers add them, together and divide them by 2.

To find the mean (also know as the avergae) we need to add all the numbers together and divide by the number of values that are present:

42+15+14+48+39 = 158

158/ 5 = 31.6 or 32

a) according to the map on the left, Central Park is about 50 blocks long by 9 blocks wide. what is the approximate area of the park? show your work.




b)lets say the area of the map is 21 square inches. you want to make q enlarged map of central park to take with you on your journey. describe how you can determine the area of the the enlarged map.




c)supposed the scale factor you will ise to enlarge the map is 5:1. what is the approximate area of the park of the park in your enlarged drawing.




d) how did you apply proportional reasoning as you worked through these problems?

Answers

it is either the second one or the last one

Answer:

For (a) the answer is 450, 50(9)=450 total blocks.

Step-by-step explanation:

For (c), you will have to use a scale of 1 to 5, so, 450(5)=2,250.

For (b), if the map is 21 square inches and you want to enlarge it to the size you want, you would have to take the total value of the original map and multiply it by whatever factor it has to be multiplied by.

Now finally for (d), I applied proportional reasoning by looking at the dimensions and adding them all together to get the area value, then comparing the area value to the enlarged figure or decreased figure.

(I did this quite a long while ago, I'm going based on my memory and math skills, sorry if I failed horrendously.)

My explanation of my work:

Keep change flip is the operation used here

So you keep 1/5 ,change the division sign to multiplication and flip the 2/1 into 1/2 so the new equation is (1/5x1/2) the answer to that is 1/10

One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month. A second smartphone plan costs $82 per month for talk and messaging and $3 per gigabyte of data used each month. Let c represent the total cost in dollars and d represent the amount of data used in gigabytes.

The system of equations {c=52+8dc=82+3d can be used to represent this situation.
How many gigabytes would have to be used for the plans to cost the same? What would that cost be?

Both plans would cost $
if
gigabytes of data are used.

Answers

Answer:

a) 6 gigabytes

b) $100

Step-by-step explanation:

Let c represent the total cost in dollars and d represent the amount of data used in gigabytes.

For the first smartphone

One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month.

Equation =

c = 52 + 8d

For the Second smartphone

A second smartphone plan costs $82 per month for talk and messaging and $3 per gigabyte of data used each month.

Equation =>

c = 82 + 3d

How many gigabytes would have to be used for the plans to cost the same?

We would equate both cost to each other

52 + 8d = 82 + 3d

Collect like terms

8d - 3d = 82 - 52

5d = 30

d = 30/5

d = 6

Therefore,

a) The number of gigabytes for the cost of both Smartphone data plans to be the same = 6 gigabytes.

b) The cost of both plans if 6 gigabytes is used =>

c = 52 + 8d

c = 52 + 8 × 6

c = $100

Step-by-step explanation:

A six sided number cube :

Sample space = (1, 2, 3, 4, 5, 6)

Non composite numbers on a six sided number cube = (1, 2, 3, 5)

Probability of an event = required outcome / Total possible outcomes
