We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
1. alternate interior angles, x= -10
2. corresponding angles, x= 30
Answer:
i have made it in above picture
Answer:
78.6m of fencing
That would cost $982.50
Step-by-step explanation:
Perimeter: 2(22.7)+2(16.6)=P
P = 78.6
Cost: 78.6*12.50
C = 982.50
Answer:
y is equal to or greater to one
y > 1 (BUT THE > HAS A DASH UNDER IT)
Step-by-step explanation:
it's a colored in circle and i was taught that that's when the point is included (that's why a dashed should be under the >)
