pillows. If each pillow costs the same amount, what is the cost per pillow, in dollars?

Answers

Answer:

96 / 6 = 32 / 2 = 16 / 1 = 16 per pillow

Step-by-step explanation:

Answer:

$16

Step-by-step explanation:

To find the cost of a single pillow, you have to divide the total cost of the pillows ($96) by the number of pillows purchased (6).

96 / 6 = 16

Therefore, the cost per pillow, in dollars, is $16. I hope this helps! Have a lovely day!! :)

Step-by-step explanation:

Skip to the bottom for image examples, read on for definitions.

Acute angles are angles less than 90 degrees.Right angles are exactly 90 degrees.Obtuse angles are 91 degrees or more.

For example, I sliced a pie, and it was an acute angle. Or I could have bought a taco and that taco has an obtuse angle, while if I just picked up a mini-square-cake, it is made of many right angles. And yes, I did draw those images myself as examples.

Answers

The function range of {y|y ≤ 5} is f(x)=-(x-4)^4+5.

Since the range has less than a sign, this means that the parabola is

facing downwards and it means that a is negative.

The range is given by

What is the vertex form of a quadratic equation?

[tex]f(x)=a(x-h)^2+K[/tex]

A 10 ft extension ladder is positioned to reach 7.4 ft up a wall. How far from the wall is the foot of the ladder.

Answers

Answer:First, draw a picture.

Distance on ground = 10 feet

Length of ladder (hypotenuse) = x          [unknown for now]

Height on wall =  x-2

The Pythagorean theorem says, for a right triangle:    a2+b2=c2

    [note: the hypotenuse, c, is always the longest side]

   102  + (x-2)2  =   x2

  100 + x2 -4x + 4 =  x2       [expand using F-O-I-L]

   100 -4x + 4 = 0                [subtract x2 from both sides]

  104 - 4x = 0                    [collect terms]

    -4x = -104               [subtract 104 from both sides]

Which transformation or sequence of transformations would produce an image that is not congruent to its pre‐image?

A translation of (x − 2, y + 9)
A translation followed by a rotation
A rotation of 270 degrees about the origin
A dilation followed by a translation

Answers

Answer:

A dilation followed by a translation

Step-by-step explanation:

A dilation would change the size of the figureHence, on changing it, the transformation will form an image that is not congruent to its pre-image

The transformation or sequence of transformations that would produce an image that is not congruent to its pre-image is:

A dilation followed by a translation.

If we follow a dilation with a translation, the image will be both resized and shifted. The combination of these transformations will result in an image that is not congruent to its pre-image.

On the other hand:

A translation of (x − 2, y + 9) will shift the object without changing its size or shape. The resulting image will be congruent to the pre-image.

A translation followed by a rotation can result in a congruent image if the rotation angle and translation distance are appropriately chosen. It depends on the specific values used in the transformation.

A rotation of 270 degrees about the origin will preserve the shape and size of the object. The resulting image will be congruent to the pre-image.

Answer:

174; 132; 203; 118; 73; 20°.

Step-by-step explanation:

1) the sum of the internal angles of the given figure is:

S=180*(n-2), where 'n' is number of the angles.

2) according to the rule above the sum of all the internal angles is 720°;

3) according to the item 2, m∠A+m∠B+m∠C+m∠D+m∠E+m∠F=720°. If all the angles are known, then it is possible to re-write this equation as:

6x+(3x+45)+7x+(4x+2)+(2x+15)+(x-9)=720;

23x=667; ⇔ x=29.

4) if x=29, then m∠A=174; m∠B=132; m∠C=203; m∠D=118; m∠E=73; m∠F=20°.

It depends if the data-set contains outliers or not.

If it does, the median should be used.Otherwise, the mean should be used.

In this problem, the weights of 4 and 5 ounces are outliers, hence the median should be used. There are 19 values, hence the median will be given by the 10th value, which is 10. Hence the median is of 10 ounces.

Answer:

Length of slope = 15.8 yd

Step-by-step explanation:

using Pythagoras theorem,

?² = 13² + 9²

?² = 169 + 81

? = √250

? = 15.8 yd

Step-by-step explanation:

According to Pythagoras theorem ,

Hypotenuse ² = Perpendicular ² + base ²

Here , we have to find the hypotenuse

perpendicular = 13ydbase = 9yd

putting the known values ,

Hypotenuse² = (13yd)²+ (9yd)²

Hypotenuse² = 169+81

Hypotenuse² = 250 yd

Hypotenuse = √250 yd

Hypotenuse = 15.8 yd
