the area of the semicircle?
The area of the semicircle is, 6.28 unit².
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
BC is the diameter of the semicircle.
And, The area of rectangle ABCD is 20 and the length of line AB is 5.
Now, We have;
The area of rectangle ABCD is 20 and the length of line AB is 5.
Let the width of rectangle = x
So, We can formulate;
⇒ 20 = x × 5
⇒ x = 4
Here, the width of rectangle is the diameter of the semicircle.
So, The radius of semicircle = 4 / 2
= 2 units
We know that;
Area of semicircle = π r
Where, 'r' is radius of semicircle.
Hence, We get;
⇒ Area of semicircle = π r
⇒ Area of semicircle = 3.14 × 2
= 6.28 unit²

Answer:
90
Step-by-step explanation:
each dot = 45 bc 540 / how many dots there are which is 12 = 45 then there are 2 dots worth of 45 making it 90
math
540/12=45
45 x 2 = 90
Answer: 135 students
Step-by-step explanation:
1. Divide 540 (total number of students) by the number of dots (12)
2. So then 540/12= 45
3. Then see how many dots are more then 5 miles away so that is 3 dots (2dots on 6 miles, and 1 dot on 7 miles)

How to find coordinates of the center of dilation?
We label points A=(x1,y1)=(1,1) A = (x1, y1) = (1,1) and A′=(x2,y2)=(3,3) A ′ = (x 2, y 2) = (3,3) to identify the centre of dilation. The centre of dilation's coordinates are then determined using the formula. (xo,yo) ( xo,yo) ( xo,yo )
What is the location of a dilation's centre?When the scale factor exceeds 1, the dilation becomes an enlargement. If it falls within the range of 0 and 1, the dilation is a contraction. The point from which the image is dilated is known as the centre of dilation (or point of dilation).

Which best describes the relationship between the two triangles below?
Triangle M N L. Angle M is 51 degrees and angle L is 36 degrees. Triangle F H G. Angle F is 51 degrees and angle G is 36 degrees.
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the third angle is unknown.
Triangle M L N is similar to Triangle F G H because of the angle-angle criterion, Angle M is similar to angle F, Angle L is similar to angle G, and Angle N is similar to angle H.
Triangle M L N may or may not be similar to Triangle F G H because the side lengths are unknown.
Answer:
Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.
Step-by-step explanation:
Triangles are similar if all of the angles are congruent and corresponding to the other triangle and the sides are proportionate. It is important to note that if the angles are congruent then the sides must be proportionate; so, the side lengths are not necessary. Additionally, the third angle theorem states that if two known angles are congruent then the third angles must also be congruent. So, the two triangles must be similar because all of the angles are congruent to their corresponding angles.
Does 9 12 15 make a right triangle?
The side lengths measuring 9 units , 12 units and 15 units make a Right Triangle because the sides satisfy the condition of the Pythagoras Theorem .
According to the Pythagoras Theorem , which states that square of the lonest side (hypotnuse) is equal to the sum of the square of the other two sides ( perpendicular and Base) ,

The decimal form of the -1 1/12 is obtained by finding the sum of -1 and -1/12 (-1/12 = -0.08[tex]\overline{3}[/tex] a recurring decimal), which is the option A
A. -1.08[tex]\overline{3}[/tex]
What is a recurring decimal?A recurring decimal is a decimal that has a digit or a group of digits that is continuously repeated in the decimal.
The specified expression, -1 1/12, can be presented as follows;
[tex]-1\dfrac{1}{12}[/tex]
The value of the specified expression in decimal form is therefore;
[tex]-1\dfrac{1}{12}= -1+\left( - \dfrac{1}{12}\right)[/tex]
[tex]- \dfrac{1}{12} = -0.08\overline{3}[/tex]
The fraction -1/12, therefore consist of a recurring decimal, with the 3 in the thousandth place after the 8 being the part that repeats.
Therefore, the value of the expression, [tex]-1+\left( - \dfrac{1}{12}\right)[/tex] is -1 + (-0.08[tex]\overline{3}[/tex])
-1 + (-0.08[tex]\overline{3}[/tex]) = -1.08[tex]\overline{3}[/tex]

The range of solutions for the given inequality is -5<y<5.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -6<1/3(6y + 12)<14.
Here, -6<(2y + 4)<14
-6<(2y + 4)
Subtract 4 on both the sides of an inequality, we get
-10<2y
Divide 2 on both the sides of an inequality, we get
-5<y
(2y + 4)<14
Subtract 4 on both the sides of an inequality, we get
2y<10
Divide 2 on both the sides of an inequality, we get
y<5
So, -5<y<5
Therefore, the range of solutions for the given inequality is -5<y<5.

If sin A = 28 53 sinA= 53 28 and cos B = 3 5 cosB= 5 3 and angles A and B are in Quadrant I, find the value of tan ( A + B ) tan(A+B).
Answer:
[tex]Tan(A+B)=\frac{264}{23}[/tex]
Step-by-step explanation:
From the question we are told that:
[tex]SinA=\frac{28}{53}[/tex]
[tex]CosB=\frac{3}{5}[/tex]
Let X be the adjective side to A
Let Y be the opposite side to B
Generally the equation for X is mathematically given by
[tex]X^2=\sqrt{53^2-28^2}[/tex]
[tex]X=45[/tex]
Therefore [tex]TanA[/tex]
[tex]TanA=\frac{28}{45}[/tex]
Generally the equation for Y is mathematically given by
[tex]Y^2=\sqrt{5^2-3^2}[/tex]
[tex]Y=4[/tex]
Therefore [tex]TanB[/tex]
[tex]TanB=\frac{4}{3}[/tex]
Generally the equation for [tex]Tan(A+B)[/tex] is mathematically given by

A cleaning company charges a fixed amount for a house call and a second amount for each room it cleans the total cost to clean six rooms is $250 and the total cost to clean eight rooms is $320 how much would this company charge to clean two rooms
The cleaning company would charge $150 for cleaning two rooms according to the fixed charges.
What is fixed amount?A fixed amount is a fixed amount or amount established by agreement or contract. This amount is usually a specified amount, does not change over time, and is usually paid on demand or by a certain date. Fixed amounts are commonly used in loans, insurance, and other financial contracts.
This cost is calculated by dividing the difference between the total cost of 6 and 8 rooms by the number of rooms cleaned (6 - 2 or 4).
= ($250 - $320)/4
= $40
This will give you a price of for each additional room.
To calculate the cost of two rooms, simply add the fixed amount of the home visit and double the cost ($40) for each additional room. That's a total of $150 for two rooms.
