A standard city block in Manhattan is a rectangle measuring 80 m by 270 m. A resident wants to get from one corner of a block to

the opposite corner of a block that contains a park. She wonders about the difference between cutting across the diagonal through the park compared to going around the park, along the streets.
How much shorter would her walk be going through the park? Round your answer to the nearest meter.

Answer:

68.4 meters shorter

Step-by-step explanation:

ok so you want to compare the distance  80 m + 270 m with the diagonal length.

the diagonal length =  root ( 80^2   +  270^2 )

diagonal length = root(6400 +  72900)

diagonal = root(79300) =281.602 m

so.

350 - 281.602 = 68.397 meters  about  68.4 meters  shorter than walking around

The number line below represents which combined inequality? number line with a closed circle on -4, shading to the left and a cl
Elena-2011 [213]
It is stated that their are closed circles on -4 and 3. This means, both -4 and 3 are also included in the interval.

The following regions are included in the range:

a) -4 
b) Numbers between -4 and 3
c) 3
d) Numbers greater than 3

So, the number line represents:
x greater than or equal to -4 and x less than or greater to 3.

Therefore, the first option gives the correct combined inequality.

Just the 3rd and 4th plz help me
svlad2 [7]

Answer:


Step-by-step explanation:

Now the key here is manipulating the scale:

For 3 every 2cm = 15mi

Divide by 2 so every 1cm = 7.5mi

So if we had 16.27cm then that would equal 16.27 x 7.5 = 122.025mi on the actual scale

Same for 4: if 1/2cm = 20mi

Then multiply times 2 and every 1cm = 40mi

So 11.73cm x 40 = 469.2mi on the actual scale

Hopefully this is right and it helps!

1. Algebra Find the values for x and y in ABCD.
Marta_Voda [28]

ANSWER

x=12, y=10

EXPLANATION

The diagonals of a parallelogram bisect each other.

This implies that;

AE=EC

4x = 5y - 2

4x - 5y =  - 2...(1)

Also, DE=EB;

2x = y + 14

y =2x - 14...(2)

Put equation (2) in (1).

4x - 5(2x - 14) =  - 2

Expand;

4x - 10x + 70 =  - 2

- 6x =  - 72

x = 12

Put x=2, into equation (2).

y = 2(12) - 14

y = 10

Ernesto has $20 in an account. The interest rate is 10% compounded annually.
chubhunter [2.5K]

The interest Ernesto will earn in 1 year to the nearest cent is 2200 cents.

<u>Given the following data:</u>

  • Principal = $20.
  • Interest rate = 10%
  • Time = 1 year.

To calculate how much interest Ernesto will earn in 1 year to the nearest cent:

<h3>How to calculate compound interest.</h3>

Mathematically, compound interest is given by this formula:

B=P(1+r)^t

<u>Where:</u>

  • B is the balance.
  • P is the principal or starting amount.
  • R is the interest rate.
  • T is the time measured in years.

Substituting the given parameters into the formula, we have;

B=20(1+0.1)^1\\\\B=20(1.1)

B = $22.

<u>To cents:</u>

B = 22 \times 100

B = 2200 cents.
