Answer:
n = -36
Step-by-step explanation:
The answer is -36 because:
1) We first have to subtract -24 and 12 to find n
-24 - 12 = -36
This is because whenever there are two negative signs, multiply it.
Negative x Negative = Positive
We have to do, 24 + 12 which is 36. Finally, we just put the greater number's sign to the answer. 24 is greater than 12, therefore, we put a negative sign before 36.
Hope this helps!
Answer:
Altogether, they had ?28
Step-by-step explanation:
Had Obi spent only ?12, they would have been even. Thus ?12 is the same as 5-2 = 3 "ratio units". So, each "ratio unit" is worth ?12/3 = ?4.
Then Obi started the day with 5·4 = 20, and Obi started the day with 2·4 = 8. Obi ended with 0, which is 8 less than Rudy.
Altogether, they started with 20 + 8 = 28 of whatever a ? is.
Answer:
²⁵C₅ = 53130
Step-by-step explanation:
number of people in the club = 25
number of people to be selected in the group to attend conference = 5
number of ways of selecting this group from 25 people is same as selecting 5 objects from 25 distinct objects = ²⁵C₅ (Selection)
= 
= 
= 21×22×23×5
= 53130
∴ <u>Number of ways of selecting this group from 25 people = 53130</u>
Answer:
Box A is greater than Box B by 34.
Step-by-step explanation:
First, you need to start with finding the surface area of every individual side on Box A we have side A, B, and C. After finding the individual area for each side, double each area because there is two of each side. This is the the same method you apply to Box B.
Then subtract the surface area of Box B from Box A.
Answer:
FGH ~ KLJ
Step-by-step explanation:
You have to write the similarities in order. Meaning, each letter of the triangle must correspond with each letter of the other triangle, in order. So if ABC is similar to LMN, then A must be similar to L, B must be similar to M, and C must be similar to N.
So,F = 91 and K = 91. They are the first part of the similarity. Then, G and L both equal 65, so they are the second part. Finally, H and J both equal 24, so they must be the third part.
Therefore, FGH ~ KLJ.
(If you are wondering about the second part: " ≅ " means congruent to and " ~ " means similarity so the ~ symbol is the right one.)
I hope this helps! Good Luck!
