The answer is <span>he lengths of the bases of the trapezoids are
trapezoid A
b=19cm, and B=35cm, b the short base and B the long base
trapezoid B
</span><span>b=19cm, and B=35cm, b the short base and B the long base
</span>
the height is h=15cm
the surface of A is A= hx(b+B) /2
so the surface is A= 15(19+35)/2=405cm²
we know that suface A =surfaceB, so Surface B= 405cm²
finally the total surface painted is 2 x 405cm²= 810cm²
the perimeter of the trapezoid A is PA=17+19+35+17=88cm
<span>the perimeter of the trapezoid B is PB=17+19+35+17=88cm
</span><span> one piece of sandpaper will not be enough to sand the edges of one trapezoid</span>
Answer:
i- alrighty then
Step-by-step explanation:
1/8 + 1/9 = 9/72 + 8/72 = 17/72
#1 Find P(all five cards are different types)
#2 Find P(Straight | five different types)
#3 Find P(Flush | five different types)
#4 Find P(#2 and #3 both occur)
#5 Subtract (#2 + #3 - #4) from 1 (not #1)
#6 Multiply #1 times #5
I'm not going to solve the whole thing but these steps aren't too difficult individually.
Answer:
Step-by-step explanation:
first piece= 1u
second piece= 3u
third piece=18 feet
maximum length for first+second piece= 100-18= 82
4u= 82
1u= 20.5
3u= 20.5x3= 61.5
<u><em>ANSWER: 61.5 feet</em></u>
