There are total 80 dimes in the jar. B/c...
n+d=200 = n=200-d
0.05n+0.1d=$14.00
0.05(200-d)+0.1d=$14.00
10-0.05d+0.1d=$14.00
10+0.05d=$14.00
-10 -10
0.05d=$4.00
0.05d/0.05=$4.00/0.05
d=80

Step-by-step explanation:
1. THEY ALL HAVE 4 RIGHT ANGLES
Yes, there is a triangle with angle measures of 30°, 70°, and 80°.
No matter what the angle measures in a triangle are, they must add up to 180° for it to be a triangle. Even if it was 178°, 1°, and 1°, it would add up to 180° and make it a triangle.
Answer:
approximately 300,000,000 meters per second
Answer:
60 ft, 120 ft, 182 ft
Step-by-step explanation:
Hi there,
To find the perimiter of a polygon, you need to add of all of the sides.
So, let's do that:
x + 2x + 3x+2
Since we are given the perimeter, we make what we just did above, equal to the perimeter
x + 2x + 3x +2 = 362
Combine lke terms...
6x + 2 = 362
Subtract 2 from both sides to start to isolate the variable...
6x = 360
Divide both sides by 6 to isolate x...
x = 60
But we're not done yet...
The length of the first side is 60 ft, the length of the second side is 2*60 which is 120 ft, and the length of the third side is 3*60 + 2 which is 182 ft.
Let's check...
Does 60 + 120 + 182 = 362?
362 = 362
Our answers are right
Hope this helps! Stay safe!
