Answer:
C. (31)(-10) = -310
Step-by-step explanation:
A. (-9)(-9) = -81
negative times a negative is a positive incorrect sign
B. (-12)(4) = 48
negative times a positive is a negative incorrect sign
C. (31)(-10) = -310
positive times a negative is a negative correct sign
D. (26)(3) = -78
positive times a positive is a positive incorrect sign
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.
The other answer choices have the wrong signs.
Multiplying 2 negatives together gives a positive, so A is wrong.
Multiplying a negative by a positive gives a negative, so B is wrong as well.
D is wrong because multiplying 2 positive numbers gives a positive number.
So, C is correct.

Simplify: (-1/3+1/9) 4^2+5/18
A)-2/9
B)32/9
C)-59/18
D)73/18
Answer:
A -59/18
or
-3/5/18-3.27...
Step-by-step explanation:
First you wanna calculate the sum
(1/3+1/9)×4²+5/18=
-2/9×4²+5/18
Then you wanna evaluate the power
(1/3+1/9)×4²+5/18=
-2/9×16+5/18
Now you are gonna calculate the product
-2/9×16+5/18=
-32/9+5/18
Last you want to calculate the sum
-32/9+5/18=
-59/18

Dina has several small clay pots. She wants to display them in order of height, from shortest to tallest. What will be the order of the pots?
Answer:
1. (2.5 2. ( 8 3. (2 1/3 4.(5
Step-by-step explanation:
The correct order from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.
It is given that Dina has several small clay pots arranged in a order.
We have to rearrange them in correct order from shortest to tallest.
What will be the correct order from greatest to least for fractions ; 1/2 , 2/2 , 3/2 , 4/2 , 5/2 , 6/2 ?
The correct order will be ; 6/2 , 5/2 , 4/2 , 3/2 , 2/2 , 1/2.
Expressing the given numbers/fractions in decimal form.
√ 8 = 2.82 which is the tallest,
2.5 = 2.5 is second tallest,
[tex]2\frac{1}{3}[/tex] = 2.33 which is third tallest,
√5= 2.23 which is the shortest.
Thus , the correct order from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.

Suppose U = {1, 2 , 3, 4, 5} is the universal set and A = {1, 5}. What is A' ?
A. A' = {1, 2 , 3, 4, 5}
B. A' = {2 , 3, 4}
C. A' = {1, 2 , 3, 4}
D. A' = {2 , 3, 4, 5}
A will be equall to {2 3 4}
The value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.
What is a set theory?The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.
Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,
U = {1, 2, 3, 4, 5
A = {1,5}
A' = {2,3,4}
Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Create an explicit formula of the sequence. Use the explicit formula to find of the
sequence. Give your answer in the answer space.

Answer:
a= n+6 n
Step-by-step explanation:
n=an−1−5
Step 1: Flip the equation.
an−6=n
Step 2: Add 6 to both sides.
an−6+6=n+6
an=n+6
Step 3: Divide both sides by n.
an n = n+6 n a= n+6 n
