HELP ASAP PLEASE.
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?
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.)

Answer: (x - 2) ^2 + (y - 6) ^2 = 25
Answer:
(x - 48)² + (y - 24)² = 64Step-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 = 24Use circle formula:
(x - h)² + (y - k)² = r²Substitute values to get required equation:
(x - 48)² + (y - 24)² = 8²(x - 48)² + (y - 24)² = 64Solve ? I need your helpppppp
Answer:
square = 8
triangle = 3
circle = 2
Step-by-step explanation:

there u go :)
the difference of two number is 28 if the larger number is three time of the smaller find the number
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
True or False:
x2 and -2x2 are like terms
Answer:
true i think....
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.

"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?
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
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.
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
You start at (8,0). You move left 6 units. Where do you end?
Answer:
(2, 0)
Step-by-step explanation:
Moving left just subtracts from the x coordinate (example: left 8 subtracts 8 from the x coordinate)

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

Kendall went to the candy store and bought 2 pounds of candy. If 1/5 of Kendall's candy was chocolate, how many pounds of chocolate candy did Kendall buy?
The answer is 1/10
This is simple division
The equation is (1/5÷2)
I did my work on a sheet of paper so i know i did this correctly
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

find the median and mean 42,15,14,48,39
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
Hope this helps!
someone help me right now please!! “15% of what number is 14?”
i need step by steps i dont know how to solve these problems
Answer:
We have, 14% × x = 15
or, 14100 × x = 15
Multiplying both sides by 100 and dividing both sides by 14,
we have x = 15 × 10014
x = 107.14
If you are using a calculator, simply enter 15×100÷14, which will give you the answer.

What is this students GPA? Class Grade English B Math A Science B Social Studies C Physical Education Spanish Art A. 2.71 B. 3.3 C. 2.0 D. 4.0
Answer:
3
Step-by-step explanation:
Finding a GPA is just like finding an average, you add up all of the different outcomes and divide it by the total amount of outcomes and you will get the average. You also need to know how many points each letter grade is worth. It is normally A=4.0 B=3.0 C=2.0 D=1.0 and F=0. In this case here is what you will add,
3+4+3+2=12
Now that you have the total number of points you need to divide the total by the total outcomes which would be,
12/4=3
3 is the final answer
