Answer:

(8, 3)

Step-by-step explanation:

The first number (8) is our x, and we can see that this point is 8 units to the right. Then the second number (3) is our y, and we can see this is 3 as the point is 3 units up.

x = right or left

      - right = positve

      - left = negative

y = up or down

      - up = positve

      - down = negative

Answer:

B = (8, 3)

Step-by-step explanation:

In the ordered pair (x, y) of point B, (8, 3):

x = 8

y = 3

Answer:

6.1, 6.107, 6.17, 6.1722

Step-by-step explanation:

Hope this helps! :)

Step-by-step explanation:

you mixed an 8% and a 12% solution together.

so, you get (8%×mass1 + 12%×mass2)/((mass1 + mass2)/2) as resulting % of the combined solution.

since the result is 10%, which is precisely the arithmetic middle

(8 + 12)/2

we see that mass1 = mass2.

in other words : the same quantity (mass) of the 8% solution and the 12% solution was mixed together.

so, 760g = 2×mass

=>

mass = 380g

380g of the 8% solution and 380g of the 12% solution were mixed together.

Answer:

After 3 days, Noah is still farther along reading.

Step-by-step explanation:

Here are the two equations:

NN = 12tt + 41

AA = 16tt + 13

Now we plug in 3 to both equations to see what page they're on after 3 days:

[tex]NN = 12(3) + 41\\NN = 36 + 41\\NN = 77 \\\\AA = 16(3) + 13\\AA = 48 + 13\\AA = 61[/tex]

After 3 days, Noah is 77 pages along and Amelia is 61 pages along.

77 pages > 61 pages so therefore Noah is still farther along.

Answer:

  8532

Step-by-step explanation:

See the attachment for the partial products and their sum.

The estimated value is about 10% less than 20·475 ≈ 9500 -950 = 8550. This indicates our answer of 8532 is probably correct.

Answer:

20 inches

Step-by-step explanation:

When the instructions say a triangle is similar, it basically means they are exactly the same unless otherwise specified.

With this, we just need to find the ratio.

We can see that DE is 6 inches while AB is 18 inches.

This means that the ratio between DEC and ABC is 1:3, respectively.

So if AC is 30, that means DC should be 10.

All we have to do now is subtract DC from AC to find AD

30 - 10 = 20

So AD is 20 inches

I'm pretty sure there is a more mathematical approach to this but this is good enough to solve any problem like this.

Answer:

20 inches

Step-by-step explanation:

Set up a proportion

BA/AC = ED/DC

You are given that BA = 18, AC = 30, ED = 6

18/30=6/

18/6 = 3

30/3 = 10 = DC

Sense DC = 10

AC-DC

30-10=20

Answer:

Lafayette Square is about 5688.89 square yards  

Step-by-step explanation:

The scale factor( ratio between the two sides) is 8 inches long to 4 inches wide or 2 to 1;  2 inches to one 1

Given the actual park is 160 feet wide ( need this measurement in inches).

so the actual part is 160 · 12 = 1920 inches wide.

Using the ratio long/ wide = long/ wide 2/1 = ?/1920.  The part is 3840 inches long.

Answer need to be in yards:  divide by 36 because 36 inches = 1 yard.

Long = 3840/36 = 320/3 yards

wide = 1920/36 = 160/3 yards

Actual area = L · W

                   = (320/3)·(160/3)

                   = 51200/9

                    = 5688.89 square yards

Step-by-step explanation:

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Distance covered = 3.7 miles

Time taken = 30 minutes = 0.5 hour

Time taken to cover 1 mile :

average time for each mile is equal to 0.135 hr or 8.1 minutes.

Answer:

58.3km

Step-by-step explanation:

58300 ÷ 1000 = 58.3km

Given:-

58,300 metres

Converting to kilometers, let's do by:-

[tex] \frac{58300 \: m}{1} \times \frac{1}{1000} km[/tex]

[tex] \frac{58300}{1000} [/tex]

[tex] => 58.3 \: km[/tex]

Therefore, in kilometers, 58300 m = 58.3 km.
