Answer:
will you have to put the options down in the ch.at since you didn't put them in the question
Step-by-step explanation:
Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
Answer: im not sure if there was supposed to be more to this problem, like how much dough was needed before 35% of the pie was eaten???? (if there is more pls comment and ill help)
Answer:
-sin(2A)
Step-by-step explanation:
1-(sin(A)+cons(A))^2
1-(sin(A)^2+2sin(A)cos(A)+cos(A)^2) :use FOIL to get it
1-(1+sin(2A))
1-1-sin(2A)
-sin(2A)
Answer:
1/5
Step-by-step explanation:
To avoid ambiguity, your negative exponent -3/2 should be enclosed in brackets or parentheses, as should your exponent 1/3:
( 25^[-3/2] )^ (1/3)
This is equivalent to:
(√25)^(-3)· (1/3), or
5^(-1), or 1/5.
