Someone help me PLEASE it’s DUE
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:
(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

58,300 meters to kilometers. Round to the appropriate number of significant digits.
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.

Answer:

Step-by-step explanation:
Noah and Amelia are reading the same book. At the beginning of the month, Noah was on page 41 and Amelia was on page 13. Noah will read 12 pages per day and Amelia will read 16 pages per day. Let NN represent the page of the book that Noah is on at the end of tt days into the month, and let AA represent the page of the book that Amelia is on at the end of tt days into the month. Write an equation for each situation, in terms of t,t, and determine whether Noah or Amelia is farther along in the book after 3 days.
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.

a scale drawing of Lafayette square is 8 inches long and 4 inches wide. The actual park is 160 feet wide. What is the actual area of the park, in square yards?
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

You've poured some 8% (by mass) alcohol solution and some 12% alcohol solution into a large glass mixing container. Now you have 760
grams of 10% alcohol solution. How many grams of 8% solution and how many grams of 12% solution did you pour into the mixing container?
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.
