Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43

Answer:
A. 15 sq in
Step-by-step explanation:
So it wants to know the area of the yellow face: we have to subtract that chunk cut out of the bottom right from the larger rectangle.
Area = length x width = 4*4 = 16 sq in. This is the area of the larger rectangle.
Area = length x width = 1*1 = 1 sq in. This is the area of the rectangle that's cut out of the yellow area.
16 - 1 = 15 sq in

What is coordinate system?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements.
Parallel lines are lines in a plane that are always the same distance apart.
The perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees
When the distance between the lines is constant then the lines are called parallel lines.
The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
In the graph, the line k is parallel to the line n and the line n is perpendicular to line n.
k || n and n ⊥ m.
Hence, the correct option is B, k || n and n ⊥ m statement is true regarding the parallel and perpendicular lines in the diagram.

Old McDonald had a farm. In one pen the old farmer had chickens and bulls together. In that pen there were 40 animals in total, but there were 130 legs. Can you figure out how many chickens and bulls are in that pen?
Answer:
There are 15 numbers of chicken and 25 numbers of bulls.
Step-by-step explanation:
The pen had chickens and bulls. The pen contains 40 animals in total. The number of legs in the pen is 130 .
Let
a = number of chicken
b = number of bull
a + b = 40................(i)
A chicken has 2 legs and a bull has 4 legs.
The total legs can be represented as
2a + 4b = 130...........(ii)
combine the equation
a + b = 40................(i)
2a + 4b = 130...........(ii)
a = 40 - b
insert the value of a in equation(ii)
2(40 - b) + 4b = 130
80 - 2b + 4b = 130
80 + 2b = 130
2b = 130 - 80
2b = 50
divide both sides by 2
b = 50/2
b = 25
Insert the value of b in equation (i)
a + b = 40
a + 25 = 40
a = 40 - 25
a = 15
There are 15 numbers of chicken and 25 numbers of bulls.

Add to eliminate x.
Subtract to eliminate x.
Answer:
add to eliminate y
Step-by-step explanation:
Because the one y is negative, you would add it to the positive y to eliminate both. A positive plus a negative is the same as subtracting from the positive number.
ex: [tex]10+-5=5[/tex] because [tex]10-5=5[/tex]
hope this makes sense :)
Answer:
Add to eliminate y
Step-by-step explanation:
This is because you'll want to add
-4x -9y = 26
8x +9y = -34
to get rid/eliminate the y
The reason why it's not subtract it because the it'll become
-4x-9y=26
-8x-9y=34
which makes the y-values not the reciprocal of each other and you wouldn't be able to eliminate the y.
And it's neither of the add or subtract to eliminate x because the numbers need to be the same numbers and reciprocal of each other
ex:
4 and -4
or
8 and -8
or
-10 and 10

A) How many 4-digit numbers are multiples of BOTH 2 and 5?
B) How many 4-digit numbers are multiples of at least one of these two numbers: 2, 5?
C) How many 4-digit numbers are neither multiples of 2 nor multiples of 5?
Answer:
A) 900
B) 5400
C) 3600
Step-by-step explanation:
A) Number of 4 digit multiples of 5:
(9999-1000+1)/5= 1800
[I added one to the 9999-1000 because it includes 9999]
Now, out of those 1800 numbers that are divisible by 5, 900 of them are even. (so they are divisible by 10 [or 5 and 2])
Therefore, the answer to A is 900
B) Number of 4 digit multiples of 2:
(9999-1000+1)/2= 4500
This means that there are 4500 even 4 digit numbers.
We have already figured out that there are 900 numbers that are divisible by both 5 and 2. 1800-900=900 4-digit numbers that are not divisible by 2, but are divisible by 5.
So if we add the 4500 (numbers that are divisible by 2) and the 900 (numbers that are only divisible by 5, but not 10), we get 5400.
C) There are 9999-1000+1= 9000 4-digit numbers. We know that there are 5400 numbers that are divisible by either 5 or 2, so 9000-5400=3600

Answer:
± 14.
Step-by-step explanation:
If we plug √196 into the calculator, we get 14.
However, every square contains a negative square root as well since multiplying two negative numbers together results in a positive number.
Therefore:
Both 14 × 14 and -14 × -14 are equal to 196.
A circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 3 m wide. Find
the area of the sidewalk in square meters. Use 3.14 for 1.
The area of the sidewalk is m?.
(Round to the nearest whole number as needed.)
Answer:
424
Step-by-step explanation:
pie r squared is area of a circle
21(squared)x3.14=1385
minus this from 24squaredx3.14 =1809
1385-1809=424
The area of the sidewalk is 226.08 m²
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The space enclosed by the boundary of a plane figure is called its area.
The area of a figure is the number of unit squares that cover the surface of a closed figure.
Area is measured in square units like cm² and m².
Given that, a circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 3 m wide. We need to find the area of the sidewalk.
To find the same, we will subtract the area of the inner circular region from the outer circular region,
The radius of the outer circular region = 21/2+3 = 10.5+3 = 13.5 m
The area of the sidewalk = πR²-πr², where R = radius of outer region and r = radius of inner region
= 3.14(13.5²-10.5²)
= 3.14 x 72
= 226.08 m²
Hence, the area of the sidewalk is 226.08 m²

Ian needs to replace two concrete sections in his sidewalk, as modeled below. Each section is 36 inches by
36 inches and 4 inches deep. He can mix his own concrete for $3.25 per cubic foot. How much money will it cost Ian to replace the two concrete sections?
Answer: $19.5
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism = width x length x height
Replacing with the values given:
Since 1= 1/12 foot
36 in /12 = 3 foot (length and wifth)
4 in /12 = 1/3 foot (height)
V = 3 x 3 x 1/3 = 3ft3
Next, we multiply it by 2 (since there are 2 sections):
3 x 2 = 6 ft3
Finally we multiply it by the cost of each cubic foot:
6 x 3.25 = $19.5

what is the sum of 9/16 and 5/16?
Answer:
7/8
Step-by-step explanation:
sum = answer to an addition problem
This means we need to add.
To add fractions with like denominators, simply add the numerators, or the numbers above the fraction sign.
9/15 + 5/16
9 + 5 = 14
numerator = 14
Keep the denominator:
denominator = 16
14/16
Simplify:
(divide the numerator and denominator by 2)
14/2 = 7
16/2 = 8
7/8
Therefore, the sum is 7/8.
The sum of the two fractions shown of 9/16 and 5/16 is 7/8.
When adding fractions, if they have the same denominator, you can simply add up the numerators and keep the denominator.
This means that the sum of 9/16 and 5/16 is:
= (9 + 5) / 16
= 14 / 16
You then need to take this to its simplest form by dividing both the numerator and denominator by their highest common factor which is 2.
= (14 ÷ 2 ) / (16 ÷ 2)
= 7 / 8
In conclusion, the sum of these fractions is 7/8.

work out an estimate for the mean time the students spent on their home work.
Answer: Mean = 52.8 mins
Step-by-step explanation:
We have lapses of 30 minutes, so we can write the average for each, this means that:
0 < t < 30 can be averaged to the middle of the range: 15 min.
Doing this, we have that:
7 students 15 min
27 students 45 min
12 students 75 min
4 students 105 min.
Now we can calculate the mean:
mean = (x1*n1 + x2*n2 + ...)/N
where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students
Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)
Mean = 52.8 mins

what is the volume of this figure ??
Answer:
210 cm³
Step-by-step explanation:
The formula for the volume of a rectangular prism is:
V = lwh
where l is the length, w is the width, and h is the height
Let's substitute the given values into this equation:
V = lwh
V = (5)(6)(7)
Multiply:
V = (5)(6)(7)
V = (30)(7)
V = 210
Therefore, the volume of the prism is 210 cubic centimeters.
