Answer:
the width is 470 ft and the length is 730 ft.
Step-by-step explanation:
Perimeter of a flag is 2l+2w
Let w = width
Let l = w+260
2(w+260)+2w=2,400
2w+520+2w=2400
4w+520=2400
4w=1880
w=470
So, the length would be 470+260, or 730
Therefore, the width is 470 ft and the length is 730 ft.
I hope this helped and have a good rest of your day!
1 whole and 1/4 substracted to 1/3 can be written as:
1 1/4 - 1/3 =
= 5/4 - 1/3
We have to find a common denominator which is 12:
5/4 = 15/12
1/3 = 4/12
So now we just substract numerators:
15/12 - 4/12 = <u>11/12</u>
Answer:
-2•5 (last one)
Step-by-step explanation:
Jumps of '-2' five times, from 0
So 0 + (-2)×5
Which is the same as -2•5

D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
Answer:
38.5 cm^2
Step-by-step explanation:
Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)
= Area (large semicircle) - area (small circle)
= π(7)² x 1/2 - π(7/2)²
22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2
= 77 - 38.5
= 38.5 cm^2
