Answer:
Krutika
Step-by-step explanation:
Lets convert each person's typing rate to words/min.
Krutika:
80 minutes = 6000 words
1 minute = (6000/80) words
= 75 words
Typing Rate: 75 words / min
Mark:
60 minutes = 4200 words
1 minute = (4200/60) words
= 70 words
Typing Rate: 70 words / min
David:
90 minutes = 5850 words
1 minute = (5850/90) words
= 65 words
Typing Rate: 65 words / min
From the above, we can see Krutika has the fastest rate of words per minute.
Answer: 36 cm
Explanation: Use Pythagorean Theorem to solve the question: a^2+b^2=c^2
A. The drop-out rate can be estimated using the equation,
d = my + b
where d is the drop-out rate, m is the slope of the line, y is the number of years from 1998 and b be the initial value. For 2008,
18.3 = m(2008 - 1998) + 38.46
The value of m from the equation is -1.12. The equation becomes,
d = -1.12y + 38.46
b. The vertical intercept of the model is when d is equal to zero.
0 = -1.12y + 38.46
The value of y from the equation is 34.34.
(34.34, 0)
c. n = 1990 + 34.34 = 2024.34.
The vertical intercept of this problem tells me that by the year 2024, the drop-out rate would be 0%.
Hello, and welcome to Brainly!
To answer this question, you must first isolate the given variable, a. Treat the < sign as an equal sign, in that what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 8a and add 6 to both side inequality.
a (-8a) - 6 (+6) < 15 (+6) + 8a (-8a)
a - 8a < 15 + 6
-7a < 21
Next, isolate the variable, a, by dividing -7 from both sides of the equation. Note that, when dividing or multiplying by a negative number, you must flip the sign:
(-7a)/-7 < (21)/-7
a < 21/-7
a > -3
a > -3 is your answer.

The correct answer should be squaring.
This is because of the order of operations. It says that all grouping should be done first (parentheses, absolute value, brackets, etc.). This expression doesn't have any of those.
Next is exponents. This expression has a square so it should be done first.
After that, we do multiplication and division in order from left to right.
Lastly, we do addition and subtraction, also in order from left to right.
