Answer:
Step-by-step explanation:
If the tip varies directly with the number of guests, it means that an increase in the amount of tip would be as a result of an increase in the number of guests and a decrease in the amount of tip would be as a result of an decrease in the number of guests.
If we introduce a constant of proportionality, k , the relationship would be
t = kg
Given that
When t = 18, g = 10, then
18 = k × 10
k = 18/10 = 1.8
Therefore, the equation representing the relationship is
t = 1.8g
The answer is B :DD
that one doesnt make sense
[When you are dividing or multiplying, the number of significant digits in the answer depends on the part of the question with the least significant digits. For example, There are 2.3 miles left for me to walk. but I can only do 1.54 miles. In the answer I will put two significant digits because the least was 2.3 which has 2 significant digits.]
#1 The answer is 4.821. but since the least # of significant digit is 1.5 which has 2. SO the Ans would be 4.8 mm^2.
#2 Ans is 2.7404 but the correct answer would be 3. because 5 has least value of significant digit. But why is 3? Because the number after 2 is greater than 7.
I hope that helps!
Solve for x:10 - (7 x^2)/3 + X^4/3 = 0
Subtract X^4/3 + 10 from both sides:-(7 x^2)/3 = -X^4/3 - 10
Multiply both sides by -3/7:x^2 = X^4/7 + 30/7
Take the square root of both sides:Answer: x = sqrt(X^4/7 + 30/7) or x = -sqrt(X^4/7 + 30/7)
