Answer:
a=35° b=90° c=55°
Step-by-step explanation:
7:18:11
total ratio=7+18+11
=36
The smallest angle(a)
7/36 x s=35
7s/36=35
7s=35x36
7s=1260
7s/7=1260/7
s=180°
second angle (b)
18/36x180
=90°
third angle (c)
11/36x180
=55°
Answer:
$760
Step-by-step explanation:
First off we need to define the amount of feet per square yard.
(3feet= 1yard)
(9 squarefeet = 1 square yard)
Now we find the total area of Amanda's living room.
12 x 15 = 180 sq feet
Now that we have the total area of Amanda's living room, we then divide the total to the number of square feet in a square yard.
180 / 9 = 20 square yards.
Amanda will need a total of 20 square yards to carpet her living room. Now we simply multiply the amount of each square yard to the total amount of square yards that Amanda needs.
38 x 20 = $760
A scale of 1:125000 means that for any length that is on the map, the real life length is 125000 times as long. This also means that for any length in real life, the length on the map is 1/125000 times as long.
So, a real life length of 10km will be represented by a map length of 10km/125000 = 0.00008km = 8cm
Answer:
1.5
Step-by-step explanation:
Using the given information the equation of the line is y = -3/2x + 2
Now replace x with any number and solve for y. Do this twice to get to points to plot on the graph:
Using X = 0:
y = -3/2(0) + 2, y = 2
First point is (0,2)
Now X = 4:
y = -3/2(4) + 2 = -6 + 2 = -4
Second point = (4,-4)
