Answer:
the answer is 0.3
Step-by-step explanation:
this is because 7 2/5 is equal to 2.8 then if you add all of the number together you will get 24.7 meaning that if you add 0.3 to that you will have your answer of 25
Write an inequality to describe the region. The solid upper hemisphere of the sphere of radius 5 centered at the origin
Answer:
[tex]x^2 + y^2 + z^2 \le 25[/tex] for [tex]z \ge 0[/tex]
Step-by-step explanation:
Given
[tex]r = 5[/tex] --- radius
Required
Determine the inequality of the region
The inequality of a region of a sphere is determined using:
[tex]x^2 + y^2 + z^2 \le r^2[/tex]
Substitute 5 for r
[tex]x^2 + y^2 + z^2 \le 5^2[/tex]
[tex]x^2 + y^2 + z^2 \le 25[/tex]
Solving further: The question says only the upper hemisphere is considered.
This implies that:
[tex]z \ge 0[/tex]
So, the equation is:
[tex]x^2 + y^2 + z^2 \le 25[/tex]
[tex]z \ge 0[/tex]

find (56)+(-17)+(-43)+(+15)
Answer:
56-17-43+15
11. ........
Answer: 11
Step-by-step explanation:
We need to start by evaluating the problem, we can simplify this equation so its easier to solve.
So the new equation will be [tex]56-17-43+15[/tex].
56 - 17 = 39
39 - 43 = -4
-4 + 15 = 11.
So [tex]56-17-43+15 = 11[/tex].
11 is the answer.
Two buildings are facing each other on a road of width 12 metre . From the top of the first building, which is 10 metre high , the angle of elevation of the top of the second is found to be 60°. What is the height of the second building ?
So easy question
Can u people solve ?
I dont think so
Answer:
[tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres
Step-by-step explanation:
You are finding the height of the building with an angle of elevation, therefore we need to solve for EC to add it to BA [10 metres] and use TRIGONOMETRIC RATIOS to arrive at our conclusion. Just in case you have forgotten what they were, here they are:
[tex]\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ[/tex]
We can now solve for EC:
[tex]\displaystyle cot\:60 = \frac{12}{EC} → ECcot\:60 = 12 \\ \\ \frac{ECcot\:60}{cot\:60} = \frac{12}{cot\:60} → 12\sqrt{3} = EC[/tex]
OR
[tex]\displaystyle tan\:60 = \frac{EC}{12} → 12tan\:60 = EC → 12\sqrt{3} = EC[/tex]
Now that you have solved for EC, you can now add it to your original 10 metres to get [tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres. As a decimal, you would get [tex]\displaystyle 30,78460969...[/tex] metres. You can go ahead and round this off if necessary.
** The reason why the cotangent [or tangent] ratio was used was because EA is equivalent to DB by the definition of a rectangle. It has two pairs of parallel and congruent sides with four right angles. Plus, that is the adjacent side of the triangle, while EC is the opposite side of the triangle, so we knew our ratios were correct.

Answer:
She is not breaking even. The discounted price is .84t, which is less than t.
Step-by-step explanation:
Retail price= 1.4
1.4×.4= .56
40% of 1.4 is .56
Subtract 40% of 1.4 from the retail price because she is marking down.
(1.4)-(.56)=.84
So the discounted price is .84t
This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.

A circular "No Parking" road sign has a diameter of 26 inches. Which measurement is closest to the area of the sign in square inches? 81.64 in.² 163.28 in.² 530.66 in.² 2,122.64 in.²
Answer: 81.64
Step-by-step explanation:i took the test
The area of the circle is 530.66 square inches.
What are the properties of the circle?The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.
Given, A circular "No Parking" road sign has a diameter of 26 inches.
From the general formula of the area of the circle:
Area = π r²
Where r = radius
in our case,
r = diameter/2
r = 26/2
r = 13 inches
Thus,
the area of the circle = pi * 13 * 13
the area of the circle = 530.93 inches²
Therefore, The area of the circle is 530.66 square inches.
