Wha t is the surface area of the square pyramid represented by the net below

Question
112
48
64
96

Answer:

The original price is 337.50

Step-by-step explanation:

If we get 20% off, we still have to pay 100-20 =80%

Let x be the original price

x *80% = 270

.80x = 270

Divide each side by .80

.80x/.80 = 270/.80

x =337.50

The original price is 337.50

Answer:

the original price was $324.

Step-by-step explanation:

since 20% of $270 is $54, you add the $54 and get $324.

hope this helps! best of luck <3 (also i didn't include tax; it didn't specify and also i don't know the tax for your region)

Answer:

[tex]a = 80[/tex]

[tex]p = 32 \sqrt{5} [/tex]

Step-by-step explanation:

p= 4 × sides

[tex]p = 4(4 \sqrt{5)} [/tex]

[tex]p = 16 \sqrt{20} [/tex]

[tex]p = 16 \times \sqrt{5 \times 4} [/tex]

[tex]p = 16 \times 2 \sqrt{5} [/tex]

[tex]p = 32 \sqrt{5} [/tex]

for question two

[tex]a = {sides}^{2} [/tex]

[tex]a = {(4 \sqrt{5} )}^{2} [/tex]

[tex]a = 16 \times 5[/tex]

[tex]a = 80[/tex]

hope it helps ❤️‍❤️‍

Answer:

Ava = 1.12 m tall

Olivia =  0.89 m tall

Step-by-step explanation:

given;

Ava is 23cm taller then Olivia,

Olivia is half the height of Lucas.

If Lucas is 1.78m tall

find:

how tall are Ava and Olivia

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

Ava = Olivia + 0.23

Olivia = Lucas / 2

Lucas = 1.78

plugin values into the equation above

Olivia = 1.78 / 2

Olivia =  0.89 m tall

Ava = 0.89 + 0.23

Ava = 1.12 m tall

Answer:

120

Step-by-step explanation:

120 * 1.15 = 138

Answer:

120

Step-by-step explanation:

115% of the number 120 is 138

Answer:

16

Step-by-step explanation:

Take the total amount and divide by the amount per candy bar

28 /1.75

16

He can buy 16 candy bars

1 pound = 16 ounces

you should make both with the same unit measurement. Let's convert them to ounces.

4 pounds= 4x16 ounces=64 ounces

ratio 10 ounces to 4 pounds= 10 ounces : 64 ounces

= 5 ounces : 32 ounces= 5 : 32

Answer:

Step-by-step explanation:

===========================================================

Explanation:

Check out the diagram below. I've added in the label (4x+13) degrees to the angle adjacent to the (9x-2) degree angle. This is valid due to corresponding angles being congruent when we have parallel lines like this.

The two angles form a 180 degree straight angle

(4x+13) + (9x-2) = 180

4x+13 + 9x-2 = 180

(4x+9x) + (13-2) = 180

13x + 11 = 180

13x+11-11 = 180-11 .... subtracting 11 from both sides

13x = 169

13x/13 = 169/13 .... dividing both sides by 13

x = 13

We can verify this by noticing that

4x+13 = 4*13+13 = 65

9x-2 = 9*13-2 = 115

So, (4x+13)+(9x-2) = (65)+(115) = 180, showing the two angles are supplementary.

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

The angles (9x-2) and (6y-1) are also a linear pair. They are adjacent and supplementary

Let's use x = 13 to find the value of y

(9x-2) + (6y-1) = 180

9x-2+6y-1 = 180

9x+6y-3 = 180

9*13+6y-3 = 180 .... plug in x = 13

117+6y-3 = 180

6y+114 = 180

6y+114-114 = 180-114 .... subtract 114 from both sides

6y = 66

6y/6 = 66/6 ...... divide both sides by 6

y = 11

To help confirm,

6y-1 = 6*11-1 = 65

which adds onto the (9x-2) = 115 degree angle to get 180.

-----------

Side note: as an alternative, you can solve 4x+13 = 6y-1 to get the same y value. This is because alternate exterior angles are congruent when we have parallel lines like this.

Answer:

sale price is $104

Step-by-step explanation:

Answer:

$104.00

Step-by-step explanation:

So we know that in the equation:

S = P - 0.20P

P is the original price and S is the sale price, which is also the original price reduced by 20%.

We are also given that the original price of a digital media player is $130.00.

We are asked to find the sales price of that digital media player. To do this, we can plug in $130.00 for P in the given equation, since it is the original price of the digital media player, and solve for S, the sales price:

S = 130 - (0.20)(130)

S = 130 - 26

S = 104

So now we found the sales price of the digital media player, which is $104.00.

I hope you find my answer helpful.

Answer: Polygon Q's area is 1/4 of Polygon P's area

======================================================

Explanation:

Imagine we had a square with side length 8. The area of this square is 8*8 = 64.

Now let's reduce each side of the square by the scale factor 1/2. So each new side is 8*(1/2) = 4. The area of this smaller square is 4*4 = 16.

Comparing the new area (16) to the old one (64), we see that the new area is 16/64 = 1/4 of the old area.

In other words,

new smaller area = (1/4)*(old larger area)

So this is one example to see why (1/2)*(1/2) = 1/4 is the area scale factor based on the linear scale factor of 1/2. In short, (1/2)^2 = 1/4. Whatever the original scale factor is, square it and you'll get the area scale factor.
