We have a polygon whose the sum of interior angles is 20 right angles (the measurement of each right angle is 90°), that means
the sum = 20 × 90°
the sum = 1800°
The sum of interior angles on any polygon could be determined using formula
sum = (n - 2) × 180°
n stands for the number of sides the polygon has
sum = (n - 2) × 180°
1800° = (n - 2) × 180°
1800°/180° = n - 2
10 = n - 2
n = 12
The polygon has 12 sides
Answer:
two tires for $35 -------------------------$70 total
three rims for $75--------------------------- $225
five headlights for $ 4.00 ----------------$20
Emma spends ($225+$70+$20) =$315
Now Emma sells them for 2 tires for $65 =130
3 rims for $136 = $408
5 headlights for $15 = $75
total money Emma makes = $613.
the profit is $613- $315= $298
the profit is $298
Answer:
2/3
Step-by-step explanation:
2(y+1) =4(5)y + 1-15
2y+2=20y+1-15-2
18y=12
divide both sides by 18
y=2/3
when you divide 2 fractions, you reverse the second fraction then use multiplication
3/5 divided by 3/15 becomes
3/5 x 15/3 = 45/15 = 3
