Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.

Step-by-step explanation:
Formula
L_n = a*r^(n-1)
Givens
a = 2
4
Solution
L_24 = 2*4^(24 -1)
L_24 = 2 * 70368744177664
Note the only way I know that you can get this answer is to use the calculator that came with windows. I don't think even my programing language would get it.
L_24 = 140737488355328
Answer:
B.adaptation
Step-by-step explanation:
The chocolate chip cookies of the cookie's club are not perfect according to Wendy, as the ratio of the chocolate chips to the cookies is more than that of a perfect cookie.
To solve this problem we have to learn about ratio. A ratio is an ordered pair written as or a:b where . It can also be defined as the number of times one number is contained in another number.
In the given problem Wendy thinks that a 353535 chocolate chips are essential for 555 cookies so that each cookie is perfect. Now let us find the ratio of the chocolate chips for each cookie.
Ratio=
or, Ratio=637:1
Therefore according to Wendy, a perfect chocolate chip cookie must have 637 chocolate chips.
Now let us find the ratio of the chips to cookie of the Cookie's Club.
Total chocolate chips=100100100
Total cookie=151515
Ratio of chips to cookies= which can be simplified to .
Therefore required ratio=
or, approximately ratio=
Now
Therefore the chocolate chip cookies of the cookie's club are not perfect according to Wendy.
