Use 3.14 for . Round your answer to the nearest tenth.
The truck will clean about
square feet of ice
Answers
Answer:
12897 square feet
Step-by-step explanation:
So first find the area of the square:
85 * 85 = 7225
Then, the two semi circles together is a full circle. Use the circle area formula,
A = πr^2
The radius (r) would be half the diameter of the circle. The diameter of the circle would be 85. So half of that is 42.5. The radius is 42.5
Now:
A = π(42.5)^2
A = 3.14(42.5)^2
A = 3.14(1806.25)
A = 5671.625
Lastly, add the two areas up for the square and circle:
7225 + 5671.625 = 12896.625
Round to nearest tenth: 12897

At a local college, 101 of the male students are smokers and 909 are non-smokers. Of the female students, 270 are
smokers and 630 are non-smokers. A male student and a female student from the college are randomly selected for a
survey. What is the probability that both are non-smokers?
Do not round your answer. (If necessary, consult a list of formulas.)
Answers
Answer:
63% Chance
Step-by-step explanation:
Remember, to find the probability of non smokers, we must find the percentage of both male and female non-smokers, and multiply them together.
So lets take all our data from this word problem first. 101 males are smokers, 909 males are not. 270 females are smokers, 630 are not.
Now, to find the percentage of non-smokers, lets add up the total amout of males, and then divide the amount of non-smokers by that number:
909+10=
1010
Ok now we know the total amount of males. Lets divide the amount of non-smokers my 1010:
909/1010
=
0.9
So this shows you that 90% of males are non-smokers.
Now lets do the same with the females:
630+270
=
900
Ok, now we know the total amount of females. Lets divide the amount of non-smoking females by this number:
630/900
=
0.7
Ok, so now we know that 70% of females are non-smokers.
Here is the final step, multipling the numbers together to find the chances of both genders being non-smokers.(I put the percentages back into decimal form when i multiplied)
0.7x0.9
=
0.63
So now we have our answer. We know that there is a 63% chance that the survey will be about 2 nonsmoking male and females.
Hope this helps!

x° + 126° = 180° and value of x is 54°
Step-by-step explanation:
Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.
We know that, in a triangle the sum of all angles Is 180°.
If two sides are equal then also two angles are also equal of that sides.
Now,
63° + 63° + x° = 180°
x° + 126° = 180°
Now, To find the value of x
x° + 126° = 180°
x° = 180° - 126°
x = 54°
Thus, The value of x is 54°
FOR VERIFICATION ONLY:-x° + 126° = 180°
54° + 126° = 180°
180° = 180°
Hence, L.H.S = R.H.S

please help me i really need help please please please
Answers
Explanation: Because this a right triangle, you can apply the pythagorean theorem which is a^2 + b^2 = c^2. a and b can be any side except the hypotenuse (the one across from the 90° angle). You take 90^2 + 75^2 = c^2. This equals 13,725 after that you can take the square root of it and you're left with ≈ 117.15375m

In the scenario above, the ranking follows a defined order with the highest level of satisfaction which a customer can report being Highly Satisfied" followed by "Satisfied" then "Neither" (meaning that customer is neither satisfied nor unsatisfied) the least level of satisfaction which a customer could report is being "Highly Unsatisfied." which is worse than being "Unsatisfied".
