Answer:
-6s-c+1
Step-by-step explanation:
(-3s-4c+1)+(-3s+3c)
We have been given the above expression. To find the sum, we simply collect the like terms and combine them;
(-3s-4c+1)+(-3s+3c) = -3s + -3s -4c + 3c + 1
-3s + -3s -4c + 3c + 1 = -3s - 3s + 3c - 4c + 1
-3s - 3s + 3c - 4c + 1 = -6s - c + 1
Therefore;
(-3s-4c+1)+(-3s+3c) = -6s-c+1
Correct Question:
Otero translated the phrase "three less than a number" into the expression 3 minus x. Which best describes the accuracy of Otero's expression?.
a. It is accurate. The phrase can be translated as "three" = 3, "less than" = subtraction, and "a number" = X, SO 3- X is
the correct expression.
b. It is inaccurate. Three is being subtracted from a number, so X-3 is what he should have written.
c. It is inaccurate. Three is being compared to a number, so 3 It is inaccurate. Three is being added to a number, so 3+ x is what he should have written.
Answer:
The answer is B because three less than a number means that a 3 is less than some number X meaning three is being subtracted from X. So equation should be X-3 rather than 3-X.
Step-by-step explanation:
For a:
(2400*2*PI)/60(seconds) = 80 PI RAD/Sec
For b:
arc length s= radius r * central angle(in radians)
= ((80*pi*7.5)/(2*pi)
=25
4 times
60/4=15
60 turtles and 15 manta rays
60+15=75
ratio= 60:75

After finding out the value of ln (52) and rounding value it to the nearest ten thousandth, we have the value as 3.9512.
Given logarithm function is ln (52).
We have to find out the value of the logarithm by rounding it to the nearest ten thousandth.
The easiest way to do this is to make use of a calculator where we can put the value of natural log.
After putting ln (52) in the calculator, we have
ln (52) = 3.951243719
In order to round the answer of ln (52) to the nearest ten thousandth, we have to first check if the number after the ten thousandth one is greater than 5 or if it is not.
Here, the ten thousandth number is 2. The number after the ten thousandth one is 4 which is less than 5. So, there will be no increase in the ten thousandth number.
Therefore, rounding the value of ln (52) to the nearest ten thousandth, we have the value as 3.9512.
