A farmer owns a rectangular-shaped farm. She knows that the length is 2 km longer than the width and the perimeter is 16 km. Find 'x', the width of her
farm.
Answer:
x = 3
Step-by-step explanation:
x + x + x + 2 + x + 2 = 16 (combine like terms)
4x + 4 = 16 (subtract 4 from each side)
4x = 12 (divide each side by 4)
x = 3
Let's check:
(3 + 2) × 2 = 10
3 × 2 = 6
10 + 6 = 16
It works.
Answer:
length= 5 km
Width=3 km
Step-by-step explanation:
Length=Width+2
L=W+2
Perimeter = 16 km
Perimeter of the rectangular field = 2(Length+Width)
[tex]16 = 2*(Width+2+Width)\\\16=2(W+2+W)\\\\16=2(2W+2)\\\\16/2=2W+2\\\\8=2W+2\\\\2W=8-2\\\\2W=6\\\\W=6/2\\\\W=3 km[/tex]
Length(L)=Width+2= 3+2=5 km
length= 5 km
Width=3 km

If f(x) = 4x^0 + (4x)^-1, what is the value of f(4)
Answer:
[tex]\frac{65}{16}[/tex] or 4.0625
Step-by-step explanation:
To solve this problem, all we have to do is input the value x = 4 into the equation and solve.
f(4) = 4(4)^0 + (4x)^-1
f(4) = 4(1) + 1/4(4)
f(4) = 4 + 1/16
f(4) = [tex]\frac{64}{16}[/tex] + [tex]\frac{1}{16}[/tex]
f(4) = [tex]\frac{65}{16}[/tex]
f(4) = 4.0625
A wire is first bent into the shape of a square. Each side of the square is 6cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 9cm, what is its width?
Hi there!
Assuming a perfect square: we know there are 4 sides in a square, and all of them have equal length. This means that every side of the square is 6 cm, and with 4 sides, that would make an overall length / perimeter of 6 + 6 + 6 + 6, or 6*4, which would equal 24 cm. This means that our wire must be 24 cm long.
Now, for the rectangle. We know with rectangles that they also have 4 sides, and in pairs of 2 in terms of length (2 of the sides have the same length, and the other two have the same length). This means we know there are 2 sides that are 9 cm, which would mean 18 cm in total. This is the total amount of wire taken up by the length, but we are looking for the width. Thus, we can see how much wire is leftover not taken up by the length by subtracting 18 from 24:
24-18=6
Now, we see that the two sides that make up the width are 6 cm long. As those two sides are equal length, we can divide 6 cm into two equal parts to see the width.
6/2 = 3 cm.
Thus, the width of the rectangle is 3 cm.
Hope this helps!
The wire, when bent into a square, has a total length of 24cm. When reshaped into a rectangle with a length of 9cm, the width must be 3cm to maintain the same total length.
Explanation:The subject of this problem is geometry and algebra. We know that a wire is bent into the shape of a square with each side being 6cm. The total length of the wire is the perimeter of the square, which can be calculated as 4 * side length, so the total length of the wire is 4*6 = 24cm.
Then the wire is reshaped into a rectangle where the length is given as 9cm. Since the total length of the wire has not changed, the perimeter of the rectangle is also 24cm. The perimeter of a rectangle can be calculated as 2*(length + width). If we set this equal to 24, we get 2 * (9 + width) = 24. Solving for width, we find that the width is 3cm.

There are 40 students playing dodge ball in a high school gym that is 100 feet long by 60 feet wide. There are 12,000 balls available in the gym to throw. What is the population density of the balls in the gym (balls per square foot)?
Answer:
2 balls/ft²
Step-by-step explanation:
The area of the gym is:
A = (100 ft) (60 ft)
A = 6,000 ft²
The population density is:
D = 12,000 balls / 6,000 ft²
D = 2 balls/ft²
Final answer:
To calculate the population density of balls in a gym, divide the total number of balls by the gym's area in square feet. In this case, with 12,000 balls and a gym of 6,000 square feet, the population density is 2 balls per square foot.
Explanation:
The question involves calculating the population density of balls in a gym. First, we need to find the area of the gym to understand the space these balls will occupy. The gym is 100 feet long and 60 feet wide, thus its area is 100 * 60 = 6,000 square feet.
Next, we're told there are 12,000 balls available in the gym. To find the population density of the balls, the number of balls is divided by the area of the gym. So, the population density is 12,000 balls divided by 6,000 square feet, which equals 2 balls per square foot.

In circle D, angle ADC measures (7x + 2)°. Arc AC measures (8x - 8)°. Circle D is shown. Points A, B, and C are on the circle. Point C is on the opposite side of points A and C. LInes are drawn from point A to point B, from point B to point C, from point C to point D, and from point D to point A. Angle A D C measures (7 x + 2) degrees. Arc A C measures (8 x minus 8) degrees. What is the measure of Angle A B C ? 36° 43° 72° 144°
Answer:
The measure of angle ABC is 36° ⇒ 1st answer
Step-by-step explanation:
Let us revise some important facts in the circle
The measure of the center angle is equal to the measure of its subtended arcThe measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arcThe vertex of a central angle is the center of the circle and its sides are radii in the circleThe vertex of an inscribed angle is a point on the circle, and its sides are chords in the circleIn circle D
∵ D is the center of the circle
∵ A and C lie on the circle
- DA and DC are radii
∴ ∠ADC is a central angle subtended by arc AC
∴ m∠ADC = m of arc AC
∵ m∠ADC = (7x + 2)°
∵ m of arc AC = (8x - 8)°
- Equate them to find x
∴ 8x - 8 = 7x + 2
- subtract 7x from both sides
∴ x - 8 = 2
- Add 8 to both sides
∴ x = 10
Substitute the value of x in the measure of ∠ADC
∵ m∠ADC = 7(10) + 2 = 70 + 2
∴ m∠ADC = 72°
∵ AB and BC are two chords in circle D
∴ ∠ABC is an inscribed angle subtended by arc AC
∵ ∠ADC is a central angle subtended by arc AC
- By using the 2nd fact above
∴ m∠ABC = [tex]\frac{1}{2}[/tex] m∠ADC
∴ m∠ABC = [tex]\frac{1}{2}[/tex] × 72
∴ m∠ABC = 36°

Does 2.1,7.2,7.5 make a right triangle
Answer: yes it does
Step-by-step explanation:
When you graph it on a graph piece of paper it is a right triangle
Answer:
2.1 , 7.2 , 7.5 does NOT make a right triangle
Step-by-step explanation:
Finding if the values make a right angled trianglethe formula for finding if its an acute , obtuse , right-angled triangle
acute [tex]c^{2} < a^{2} + b^{2}[/tex]
obtuse [tex]c^{2} > a^{2} + b^{2} \\[/tex]
right angled [tex]c^{2} = a^{2} + b^{2}[/tex]
c is the hypotenuse
a and b are the adjacent and the opposite
the values given are 2.1 , 7.2 , 7.5
hence :
c would be 2.1
a would be 7.2
b would be 7.5
now we can put this into the right angled triangle formula to see if its correct.
[tex]c^{2} = a^{2} + b^{2}[/tex]
lets first see the value of [tex]a^{2} + b^{2}[/tex]
= 7.2^2 + 7.5^2
[tex]a^{2} + b^{2}[/tex] = 108.09
to check if its a right angled triangle we check if the value of c^2 gives 108.09.
find the value of [tex]c^{2}[/tex]
= 2.1 ^2
[tex]c^{2}[/tex] =4.41
hence 4.41 is NOT equal to 108.09
hence its not a right angled triangle but rather an acute angle.
2.1 , 7.2 , 7.5 does NOT make a right triangle
You start at (-5, 5). You move down 6 units and up 5 units. Where do you end?
Answer:
(-5, 4)
Step-by-step explanation:
if you are moving up and down only the y part of the coordinate will change so 5 going 6 down would put you at -1 then going 5 up would put you at 4
Final answer:
Starting at (-5, 5), moving down 6 units and then up 5 units results in a final position of (-5, 4).
Explanation:
If you start at the point (-5, 5) and then move down 6 units, your vertical position decreases by 6. That means you subtract 6 from 5, the y-coordinate, resulting in -1. However, if you then move up 5 units, you're adding 5 back to your y-coordinate. So, you take -1 and add 5, which results in 4. Your final position then is still at the same x-coordinate, -5, but with a new y-coordinate of 4. Therefore, the point you end up at is (-5, 4).
Is -x + 4y=5 in Standard form of a Linear Function or not?
Answer:
Yes, it is in Standard Form.
Step-by-step explanation:
A linear function in Standard Form would look like:
Ax + By = C
where A, B, and C are real numbers.
A good way to check if a linear function is in Standard Form is by checking if the only the variables and coefficients found on one side of the equation and a real number is found by itself on the other side.
The linear function, -x + 4y = 5, has only the variables and coefficients on the left side of the function, and a real number (5) by itself on the right side.
The linear function, -x + 4y = 5, is in Standard Form.

To answer the student's question, the identification of a polygon and its perimeter and area calculation depend on analyzing the given vertices, using the distance formula to calculate the perimeter, and appropriate area formulas related to the specific polygon identified.
Explanation:The student is asking about the identification of a polygon with four given vertices and the calculation of its perimeter and area. To identify the polygon, we need to analyze the given points P(−6,2), A(−3,3), T(0,2), and H(−3,1). By plotting these points and connecting them, we could determine the shape and properties of the polygon.
Once the polygon is identified, we can calculate the perimeter by finding the distance between each pair of consecutive vertices (sides of the polygon) and summing them up. The area can be found using the appropriate formula, which is dependent on the type of polygon we identify.
Without the explicit calculations included in the student's question, it is difficult to verify the exact answer among the choices presented. However, we can guide them to use the distance formula for the perimeter and, depending on the shape, utilize formulas such as for a rhombus or parallelogram to find the area. For example, the area of a parallelogram is the base times height, and for a rhombus, it can also be calculated as half the product of its diagonals.
