Answer:

The height of the lamp is  18.33 ft

Step-by-step explanation:

We can think in two triangle rectangles, one with cathetus of:

5.5ft and 6ft (the one formed by the woman ad her shadow)

And another triangle with cathetus equal to:

6ft + 14ft (the distance between the end of the shadow and the lamp)

And the other cathetus is the height of the lamp, H.

As bot triangles will share an angle (the one formed by the end of the shadow and the hypotenuse) then the triangles are equivalent, so the quotient between their cathetus will be equal, this is:

H/(6ft + 14ft) = 5.5ft/6ft

H/(20ft) = 5.5ft/6ft.

H = (5.5ft/6ft)*20ft = 18.33 ft

Answer:1. distributive property

2. commutative property (the order of 8x and -24 is swapped)

3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)

4. commutative property (the order of 8x and -16 is swapped)

5. distributive property

      Coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.

            Rule for the transformation will be,

            P(x, y) → P'(-x, -y)

            Rule for the transformation will be,

            P(x, y) → P'(x - a, y + b)

            Rule for the transformation will be,

            P(x, y) → P'(-x, y)

By using these rules,

"If a point A(-4, 3) is rotated 180° about the center (0, 0)"

Rule for the transformation,

P(x, y) → P'(-x, -y)

A(-4, 3) → B(4, -3)

"If a point A(-4, 3) is translated 2 units right and then reflected across x-axis."

Rule for the transformation,

P(x, y) → P'[(x + a), -y]

A(-4, 3) → C[(-4+2), -3]

            → C(-2, -3)

"If a point A(x, y) is reflected across y-axis, then translated by 2 units to the right"

Rule for the transformation,

P(x, y) → P'[(-x + a), y]

A(-4, 3) → D[(4 + 2, 3]

            → D(6, 3)

    Therefore, coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.

Answer:

C. Natasha has been charged by $1.85 for her purchase.

Step-by-step explanation:

Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase

From the question, we are to determine if Natasha has been billed correctly for her purchase

From the given information,

She purchased  

3 hard cover books for $19.95 each

3 × $19.95 = $59.85

and

1 book on tape for $17.43

1 × $17.43 = $17.43

Total purchase = $59.85 + $ 17.43

= $77.28

But, the site says that taxes paid by the customer are 7.25% of the total purchase price

∴ The tax Natasha would pay = 7.25% × $77.28

= 0.0725 × $77.28

= $5.60

Add to the total purchase,

Present bill = $77.28 + $5.60

Present bill = $82.88

Then, she selects standard shipping.

According to the shipping charges,

For amount of purchase between $50 - $100, Standard shipping costs $6.35

∴ Total bill = $82.88 + $6.35

Total bill = $89.23

But, the company bills her credit card $91.08

Since, $91.08 is more than her total bill, $89.23, then, Natasha has been over charged.

$91.08 - $89.23 = $1.85

Hence, Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase.

Answer:

The coordinates of Z is (-8,12)

Step-by-step explanation:[tex]\frac{2+x^{2} }{2}= -3 \\\frac{8+y^{2} }{2} = 10[/tex]

You multiply -3 by 2 to get -6 then multiply 10 by 2 to get 20

then you create the equations [tex]2+x^{2} =-6\\8+y^{2} =20[/tex] you subtract 2 by -6 and you get -8 (x coordinate) and you subtract 8 by 20 to get 12 (y coordinate)

To check your answer you use the Midpoint formula [tex](\frac{x^{1}+ x^{2} }{2} )(\frac{y^{1}+y^{2}}{2}) =M[/tex]

[tex]\frac{2+-8}{2} =\frac{-6}{2} = -3\\\frac{8+12}{2} =\frac{20}{2} =10[/tex] and you get your midpoint.

Hey there! I'm happy to help!

To find the area of a triangle you multiply the base by the height.

We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.

To find the area of a triangle, you just multiply the base by the height then divide by 2.

5(8)=40

40/2=20

The area is 20 square units.

Answer:

B) $3.56

Step-by-step explanation:

The price of one egg: $1.69

The price of a slice of bacon: $1.49

The price of a glass of orange juice: $1.09

Sara buys 2 eggs, 1 slice of bacon, and 1 glass of orange juice.

(2 eggs x $1.69) + (1 bacon x $1.49) + (1 glass of oj x $1.09) =

($3.38) + ($1.49) + ($1.09) = $5.96

Next, add the total gotten with the sales tax.

Sales tax: $0.48

$5.96 + 0.48 = $6.44

Then, subtract the total from the $10 that she used to pay:

$10 - 6.44 = $3.56

B) $3.56 is your answer.

Answer:

3.56

Step-by-step explanation:

because first, you 1.69$ dollars 2 times since your ordering it 2 times which gets you 3.38 $ next you add 1.49$ dollars because that's what a slice of bacon cost, then add1.09 since that's what a cup of orange juice cost. Then add  0.48 cents because that's the sale tax, at the end when you add everything up you get 6.44$ then subtract that from 10.00, then you get your answer!
