The area if a dog kennel is 20 square feet. If the kennel is 4 feet.what is the width of the kennel?

Answers

Final answer:

The width of the dog kennel is 5 feet, obtained by dividing the area (20 square feet) by one of the dimensions provided (4 feet).

Explanation:

The student is asking for the width of a dog kennel, given that the area is 20 square feet, and one dimension (possibly the length) is given as 4 feet. To find the width, we can use the formula for the area of a rectangle, which is Area = Length × Width. Since the area is given as 20 square feet and the length is given as 4 feet, we can rearrange the formula to solve for the width:



Width = Area ÷ Length



Width = 20 square feet ÷ 4 feet = 5 feet



Therefore, the width of the dog kennel is 5 feet.

Final answer:

The width of a dog kennel with an area of 20 square feet and a length of 4 feet is found to be 5 feet using the area formula for rectangles, which is Area = Length × Width. The width of the kennel is 5 feet.

Explanation:

To determine the width of a dog kennel with an area of 20 square feet and a length of 4 feet, we can use the formula for the area of a rectangle, which is:

Area = Length × Width

We have the area (20 square feet) and the length (4 feet), so we can solve for the width:

20 square feet = 4 feet × Width

To find the width, we divide both sides of the equation by the length (4 feet):

Width = 20 square feet / 4 feet

Width = 5 feet

Therefore, the width of the kennel is 5 feet.

when the value of a dependant variable decreases at the independent variable increases the function is said to be.....

Answers

When the value of a dependent variable decreases as the value of an independent variable increases, the function is said to be a decreasing function.

If we graph such a function, as x goes from 0 to the right (getting larger), the y value will decrease; we would be able to physically see the graph decrease.

If the value of a dependant variable decreases as the independent variable increases the function is said to be an inverse function.

Answer: 
The area of triangle QUV is 24 square feet

-----------------------------------------------

Explanation:

Segment TV is the base of the green parallelogram PRTV
The height is segment RS which is 8 ft. This is marked as the perpendicular dashed segment line (note the right angle marker). RS is perpendicular to SV, which in turn means RS is perpendicular to TV as well.

Area of Parallelogram = Base*Height
96 = TV*RS
96 = TV*8
96/8 = TV
12 = TV
TV = 12

Segment TV is composed of TU and UV, both of which are congruent segments. The single tickmarks show this. The instructions also state "the lengths of segment TU an segment UV are equal"
So TU = UV
TU + UV = TV
UV + UV = TV
2*UV = TV
2*UV = 12
UV = 12/2
UV = 6

The height of triangle QUV is also RS = 8 because triangle QUV is completely enclosed inside the parallelogram, and because RS is perpendicular to UV. The base of triangle QUV is the segment UV = 6

Area of triangle QUV = (base)*(height)/2
Area of triangle QUV = UV*RS/2
Area of triangle QUV = 6*8/2
Area of triangle QUV = 48/2
Area of triangle QUV = 24 square feet

Quadrilateral KLMN is a rectangle. The coordinates of L are L(1,-4), and the coordinates of Mare M(3,-2). Find the slopes of sides KL, LM, MN, and NK.

Answers

L(1, -4)=(xL, yL)→xL=1, yL=-4
M(3, -2)=(xM, yM)→xM=3, yM=-2

Slope of side LM: m LM = (yM-yL) / (xM-xL)
m LM = ( -2 - (-4) ) / (3-1)
m LM = ( -2+4) / (2)
m LM = (2) / (2)
m LM = 1

The quadrilateral is the rectangle KLMN
The oposite sides are: LM with NK, and KL with NK
In a rectangle the opposite sides are parallel, and parallel lines have the same slope, then:
Slope of side LM = m LM = 1 = m NK = Slope of side NK
Slope of side NK = m NK = 1

Slope of side KL = m KL = m MN = Slope of side MN

The sides KL and LM (consecutive sides) are perpendicular (form an angle of 90°), then the product of their slopes is equal to -1:
(m KL) (m LM) = -1
Replacing m LM = 1
(m KL) (1) = -1
m KL = -1 = m MN

Answer:
Slope of side LM =1
Slope of side NK =1
Slope of side KL = -1
Slope of side MN = -1

The area of the mural is 1056 in² and the base is 32 inches. We have to determine the height of the mural.

Area of parallelogram = [tex] b \times h [/tex]

where 'b' is the base and 'h' is the height.

For what value of c is the relation a function? [(2,8) (12,3) (c,4) (-1,8) (0,3)]
a -1
b 1
c 2
d 12

Answers

1 is the only number that won't duplicate a value.

Answer:  The correct option is

(b) 1.

Step-by-step explanation:  We are given to find the value of c for which the following relation is a function :

R =  {(2,8) (12,3) (c,4) (-1,8) (0,3)}.

We know that

a relation is a function if each first element is associated with only one second element.

Since the first elements in R are 2, 12, -1 and 0, so, the value of c cannot be equal to these four values.

Therefore, the only option for c is 1.

Thus,  c = 1.

Option (b) is CORRECT.

We know that angles on a straight line sum to 180°, and we can see that 90° has already been defined on the left top left hand, leaving us with 90° on the top right hand. We are given 47°, so that must mean that the angle between the right angle and the 47° angle is:
90-47= 43°
Opposite angles around a 360° point are equal, and we see that angle x is opposite the 43° that we just found out. Therefore, x= 43°

find the values of x and y

Answers

The first step to solve this problem is to formulate equations. Since the triangle has two equal sides, you can conclude that the angles adjacent to the sides are equal which means:

3x – 11 = 2x + 11

We can now solve for the value of x:

3x – 2x = 11 + 11

x = 22

The sum of the angles of a triangle is 180 so we can formulate another equation:

3x – 11 + 2x + 11 + 2y = 180

5x + 2y = 180

Remember that the value of x is 22 so you should substitute the value of x:

5(22) + 2y = 180

110 + 2y = 180

2y = 180 – 110

2y =70

y = 35

during a festive season a shop offered a discount of 20 percent on the marked price of all items find the SP of 3 trousers mardep at rs 1800 each and two t shirts marked at rs 550 each

Answers

Think of the retail price as the whole price or 100%. Since the items are discounted 20% you end up paying 80% of the retail price for each item. 80% of the retail price is the sale price.

TROUSERS
We need to find 80% of 1800. Percent means out of 100 so we can represent it using [tex] \frac{80}{100} [/tex] or .80 whichever is easier for you to work with. Multiply this by 1800 and you have your sales price for 1 trouser. That is, the sales price for a trouser is (1800)(.8) = 1440.

SHIRTS
Same as we did for trousers we multiply the price of a shirt (550) by (.8) to get the sale price. It is 440.

3 TROUSERS AND 2 SHIRTS
The sales price for 3 trousers and 2 shirts is (3)(1440) + (440)(2) = 5200

NOTE
I noticed that you didn't include currency (dollars, pounds, euros, for example). If these are dollars then the price of a trouser might be $18.00 as opposed to 1800 which seems really high. Similarly I would expect 18,00 Euros as opposed to 1800 Euros for a pair of pants. If this is the case take the answers given above and merely insert a decimal point to spaces from the left (or in Europe and other parts of the world a comma).

What is x+2=-x+-2? Can you plz do it step by step!

Answers

To solve this equation, we are going to isolate the variable x.  To do this, we are going to begin by adding x to both sides because this will cancel out the negative x on the right side of the equation.

x + 2 + x = -x + x - 2
When we combine like terms, we get:
2x + 2 = -2
Next, we will try to continue to isolate the variable by subtracting 2 from each side to get the 2x term on the left by itself.
2x + 2 -2 = -2 -2 
When we combine like terms, we get:
2x = -4
Finally, to get x by itself we must divide by 2 to undo the multiplication of the coefficient of the term 2x.
2x/2 = -4/2
When we perform the division, we get:
x = -2
Therefore, x = -2.
We can check this answer by plugging it back into the original equation.  Our answer is verified because 0=0.
Your answer is that x = -2.

Kyle and his brother have a marble set. Of the marbles, 12 are blue. This represents 50/100 of all the marbles. What decimal is equivalent to 50/100

Answers

The decimal equivalent to 50/100 is 0.50, which is found by dividing 50 by 100.

The decimal equivalent to 50/100 is 0.50. This is because 50/100 is the same as dividing 50 by 100, which gives you 0.50.

This conversion is a standard way of expressing fractions where the denominator is 100, and it's commonly used to convert fractions into percentages or decimals.

For example, to convert 1/4 to a percent, you multiply by 25 (since 4 times 25 equals 100) to get 25 percent, which is equivalent to the decimal 0.25.

So, 50/100 is equivalent to 0.5 as a decimal.

What is the GCF of 95,42 and 97?

Answers

the greatest common factor  is 1
Final answer:

The GCF of 95, 42, and 97 is 1 because the prime factorizations of these numbers do not share any common factors other than 1.

Explanation:

To find the Greatest Common Factor (GCF) of the numbers 95, 42, and 97, we need to look for the highest number that can divide all three numbers without leaving any remainder. When considering 95, 42, and 97, we notice that:

95 is a product of the prime numbers 5 and 19,42 is a product of the prime numbers 2, 3, and 7,97 is a prime number itself, hence it only has 1 and 97 as its factors.

Since the prime factorization of these numbers does not share any common factors other than 1, the GCF of 95, 42, and 97 is 1.

An artist is deciding between two different triangular shapes to use for a sculpture. The first triangle has a base of 20 feet and a height of 5 feet. The second triangle has a base of 25 feet. If the two triangles have the same area, what is the height of the second triangle?

Answers

4 i belive altho  i could be way wrong

The height of the second triangle is 4 feet, which is found by using the formula for the area of a triangle (A = bh/2) and equating the area of the first triangle to that of the second.

To find the height of the second triangle with the same area as the first, we use the formula for the area of a triangle, A = bh/2, where b is the base and h is the height. The area of the first triangle with a base of 20 feet and height of 5 feet is:

A1 = (20 feet * 5 feet) / 2 = 50 [tex]feet^2[/tex]

Since the second triangle must have the same area, we can set up the equation:

50 feet2 = (25 feet * h2) / 2

Solving for the height (h2) of the second triangle:

100 feet2 = 25 feet * h2h2 = 100 [tex]feet^2[/tex] / 25 feeth2 = 4 feet

Therefore, the height of the second triangle is 4 feet.

The two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

What is Expression?

An expression is combination of variables, numbers and operators.

Robbie's number = 4J + 9, where J is Jennie's number.

Now we can use this expression to find Willie's number:

Willie's number = 3(4J + 9) - 2 = 12J + 25

So one equation that describes Willie's number is:

W = 12J + 25

Kylie found another expression that equals Willie's number, so we can find it by solving for J in Robbie's expression and substituting it into Willie's expression:

Robbie's number = 4J + 9

4J = Robbie's number - 9

J = (Robbie's number - 9)/4

Substitute this expression for J into Willie's expression:

W = 12J + 25

W = 12[(Robbie's number - 9)/4] + 25

W = 3(Robbie's number - 9) + 25

W = 3(4J + 9 - 9) + 25 (substituting 4J + 9 for Robbie's number)

W = 12J + 34

So another equation that describes Willie's number is:

W = 12J + 34

Therefore, the two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

Quadrilateral ABCD ​ is inscribed in this circle.



What is the measure of angle C

Answers

Hello,

When we have a quadrilateral inscribed in a circle, the opposite angles add up to 180 degrees (supplementary).

Therefore, we can write and solve the following equation first with angles B and D.
3x + 9 + 2x - 4 = 180
5x + 5 = 180
5x =175
x = 35

Then, sub 35 in the expression for angle A and you will get:
2(35) + 3
70 + 3
73

Angle A is 73, that would make angle C equal to 107 degrees, because 180 - 73 = 107.

Josie has /60 cubic centimeter of candle wax. She wants to make a hexagonal prism candle with a vase area of 21 square centimeters and height of 8 centimeters. She also wants to make a triangular prism candle with a height of 14 centimeters. Can the bass area of the triangular prism candle be 7 square centimeters

Answers

If Josie only has 60 cm^3 of wax, she doesn't have enough for either model candle.

The candle volume (V) is the product of base area (B) and height (h).

V = Bh
For the hex candle,
.. V = (21 cm^2)*(8 cm) = 168 cm^3

For the triangular candle,
.. V = (7 cm^2)*(14 cm) = 98 cm^3

Both candles are more than 60 cm^3.

The triangular candle is less than 160 cm^3. If that is the volume of wax Josie has, then she could make one of those.
