Answer:
240
Step-by-step explanation:
To evaluate 19^2 - 11^2, we have to use a special product pattern. Since this expression is in the form a^2 - b^2, we use the pattern (a + b)(a - b).
Therefore, the answer is 240.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
13 levels
Step-by-step explanation:
Direct variation can be expressed using the formula:
y = kx, where 'k' is the constant of variation
Since Michael can move up 5 levels in 55 minutes:
n = km, where 'n' is the number of levels and 'm' is the number of minutes:
5 = 55k
k = 1/11
To find the number of levels after 143 minutes:
n = (1/11)(143)
n = 13 levels
Answer:
The correct answer would be true. Reversing the statement clause and inserting a "not" in a if- then statement will also make the new statement true. For example, "If I eat this, then give me five dollars". The reverse would be " If I do not eat this, then do not give me five dollars". Both sentences mean the same.
Step-by-step explanation:
Answer:
l x - 9 l ≤ 0.3y
Step-by-step explanation:
Let x is the length of the pipe
Let y is the length of the diameter
Given that:
- A pipe is to be cut to a length of 9 accurate, we have : x - 9
- Within three tenths of its diameter : 0.3 y
So we have the inequality that model this situation is:
l x - 9 l ≤ 0.3y
Hope it will find you well.
