Answer:
x = 7/2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions

an ice fisherman wishes to cut a hole in the ice which has a diameter of 30 cm. How far around must he cut to create this hole?
Given:
Diameter of the hole = 30 cm
To find:
The area of the hole.
Solution:
The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:
[tex]r=\dfrac{30}{2}[/tex]
[tex]r=15[/tex]
Area of a circle is:
[tex]A=\pi r^2[/tex]
Putting [tex]\pi = 3.14[/tex] and [tex]r=15[/tex] in the above formula, we get
[tex]A=(3.14)(15)^2[/tex]
[tex]A=(3.14)(225)[/tex]
[tex]A=706.5[/tex]
Therefore, the area of the hold is 706.5 square cm.

Which of the following represents the graph of the equation y = 1/2x?
Answer:
(B)
Step-by-step explanation:
Here's what we know about the equation:
- it's a positive equation
- the y-intercept is (0,0)
- the slope is 1/2
Because the equation is positive, this means the graph will increase up from left to right, so you can cross out answer choice A & D.
To find out if B or C has the right slope, you can either plug in points or use the rise/run method.
I'm going to use both methods to figure out which answer choice is correct:
Plug in points method:
Let's plug in the value 2 in to the equation y = 1/2x.
1/2 * 2 = 1
So at (1,2) the function should include that point.
Only B has (1,2), so that's your answer.
Rise/run method:
Rise/run is a method used to figure out the slope of a function or draw a function on a graph.
Rise corresponds to the numerator. In this case, 1.
Run corresponds to the denominator. In this case, 2.
We are going to start at (0,0) and go up 1 (rising 1 unit) and go 2 to the right (running 2 units). After this, we should arrive at a point on the graph.
Only answer choice B does this.
**Reminder: be careful, the each blue line on the graph ISN'T a whole number interval; it uses 1/2 intervals.

c) A building owner fixed the cost of his building as Rs 15,84,000 and the price
above the fixed cost goes to an agent as his commission. If the agent sold it for
Rs 16,71,120, find his commission percent.
Plz solve it .
Answer:
5.5%
Step-by-step explanation:
Firstly, we find the difference between the fixed cost and the price above the fixed cost
We have this as;
1, 671,120 - 1,584,000 = 87,120
now, we have to divide this value by the fixed cost and express as a percentage
we have this as;
87,120/1,584,000 * 100% = 5.5%

Answer:
The correct answer, pertaining to the proposed interrogate, is acknowledged as x = 3.
Step-by-step explanation:
To evaluate for such, a comprehension of linear data must be obtained:
Slope = rise/run, defined as the agglomerate distance between two differentiated points.
X-intercept: The peculiar point in which linear data is observed to intersect the x-axis.
Y-intercept: The peculiar point in which linear data is observed to intersect the y-axis.
If there is a vertical line intersecting the x-axis, the particular point (x, y) is identified as what x is equated to.
Likewise, if there is a horizontal line intersecting the y-axis, the particular point (x, y) is identified as what y is equated to.
Thus, the following must be applied to the interrogate:
- Vertical line, thus determine the point in which the data intersects the x-axis.
- Such is identified as (3,0).
Thus, since that is the only linear figure intersecting at such peculiar axis, 3 is the equated value of x.
Hence, x = 3.

Answer:
3[tex]\sqrt{11}[/tex] + 2[tex]\sqrt{11}[/tex] = 5[tex]\sqrt{11}[/tex]
Step-by-step explanation:

[tex]\sqrt{44}[/tex] = [tex]\sqrt{(4)(11)}[/tex] = 2 [tex]\sqrt{11}[/tex]
3 [tex]\sqrt{11}[/tex] + 2 [tex]\sqrt{11}[/tex] = 5 [tex]\sqrt{11}[/tex] (add like terms. Think of the [tex]\sqrt{11}[/tex] like x's.)

Simplifying the radicals

How to answer this? A farmer had 455 ducks and chickens. He sold 2/5 of the ducks and bought another 104 chickens. As a result, the number of ducks is 2/3 the total number of animals in the end. (a)Find the number of chickens the farmer had at first. (b)Each duck is sold at a price of $28. How much did the farmer collect from the sale?
Answer:
(a) 25
(b) $4816
Step-by-step explanation:
Let's say the starting amount of ducks is d, and the starting amount of chickens is c. Since there are only ducks and chickens, we can say that d + c= 455.
Next, the farmer sells 2/5 of the ducks, so we subtract 2/5 of the ducks so that the ending duck amount is d - (2/5)d = (3/5) d
After that, the farmer buys another 104 chickens, so we add 104 chickens to the current amount of chickens to get the ending chicken number as 104+c
Given the ending duck and chicken count, we can say that the ending farm animal count (we can represent this as a) is (3/5)d + 104 + c = a
The number of ducks is 2/3 the total number of animals at the end, so (3/5)d = (2/3)a
Let's list our equations out so it is easier to solve:
d+c = 455
(3/5)d + 104 + c = a
(3/5)d = (2/3)a
We have three equations and need to solve for three variables. One common variable in all three equations is d, so it might help if we put everything in terms of d.
Starting with d+c=455, if we subtract d from both sides, we get c=455-d. We can substitute this in the second equation to get
(3/5)d + 104 + 455 - d = a
-(2/5)d + 559 = a
(3/5)d = (2/3)a
Next, we can substitute for a. If we multiply both sides by 3 and then divide by 2 in (3/5)d = (2/3)a , we get
(9/10)d = a
Substitute that in to the second equation to get
-(2/5)d + 559 = (9/10) d
-(4/10)d + 559 = (9/10) d
add (4/10)d to both sides to isolate the variable and its coefficient
(13/10)d = 559
multiply both sides by (10/13) to isolate the coefficient
d = 430
Therefore, the starting number of ducks is 430 and the starting amount of chickens is 455-430 = 25
For (b), 2/5ths of the ducks are sold, so this is (430) * (2/5) = 172. Each duck is sold for 28 dollars, so this is 172*28=$4816 as the total price
