the rectangle needs to be 12 feet long, how long will the other sides be?
300 sq ft
22 ft
I need help

Answers

Answer:

Rectangle area:

A = lw

Given:

l = 12 ft, A = 300 ft²

Find w:

12w = 300w = 300/12w = 25 ft#2

Planet x is 23 of a light-year away from Earth. Planet Y is 13 of a light-year away from Earth. How much farther away is Planet X?

Answers

Answer:

Planet X is 1.77 times further from Earth than Planet Y.

Step-by-step explanation:

Given that Planet X is 23 of a light-year away from Earth, while Planet Y is 13 of a light-year away from Earth, to determine how much farther away is Planet X the following calculation must be performed:

13 = 1

23 = X

23/13 = X

1.769 = X

Therefore, Planet X is 1.77 times further from Earth than Planet Y.

Answer:

Step-by-step explanation:

[tex] In\: \odot Y, [/tex] WZ is tangent to the circle at point Z and YZ is radius.

[tex] \therefore YZ \perp WZ[/tex]

(tangent radius theorem)

[tex] \therefore m\angle WZY = 90\degree [/tex]

Since, side opposite to 90° angle is called hypotenuse.

So, x represents the length of hypotenuse of [tex] \triangle WYZ[/tex]

Thus, by Pythagoras Theorem

[tex]x = \sqrt{ {24}^{2} + {10}^{2} } \\ \\ = \sqrt{576 + 100} \\ \\ = \sqrt{676} \\ \\ = 26[/tex]

Answer:

this answer is not right because the Y is not 90 degrees the Z angle is 90 degrees so the answer should be 26

if the trangle is right trangle use Phythagoras

Gina can trade empty bottles for money at the grocery store. She returned a few bottles worth $0.10 each and 6 bottles worth $0.05 each . The clerk paid Gina $0.80 for all of the bottles . How many bottles worth $0.10 did Gina return?

Answers

Answer:

5 bottles

Step-by-step explanation:

a total of $0.80 was paid

6 $0.05 bottles were returned= $0.05×6= $0.30

remainder= $0.80-$0.30= $0.50

amount of $0.10 bottles returned= $0.50÷$0.10= 5

Mary buys a laptop that originally cost $1,340.00. It is on sale for 15% off. What is the final price?

Answers

Answer: [tex]\$1139[/tex]

Step-by-step explanation:

Given

The original cost of the laptop is [tex]\$1340[/tex]

A sale of 15% is applicable on it

The buyer has to pay 15% less

So, the effective price of the laptop is

[tex]\Rightarrow 1340-15\%\times 1340\\\Rightarrow 1340(1-0.15)\\\Rightarrow 1340\times 0.85\\\Rightarrow \$1139[/tex]

So, the final price of the laptop is [tex]\$1139[/tex].

) () = 2 − 6 + 13 Translate f(x) 7 units to the left and down 5 units. Write your new function in vertex form

Answers

Answer:

[tex]y= (x -4)^2 - 1[/tex]

[tex]Vertex = (4,-1)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2 + 6x+13[/tex]

Required

7 units left and 5 units down

First, we have: [7 units left]

The rule is:

[tex](x,y) \to (x-7,y)[/tex]

So, we have:

[tex]f(x) = (x - 7)^2 + 6(x -7)+13[/tex]

Next, we have: [5 units down]

The rule is:

[tex](x,y) \to (x,y-5)[/tex]

So, we have:

[tex]f'(x) = (x - 7)^2 + 6(x -7)+13 - 5[/tex]

[tex]f'(x) = (x - 7)^2 + 6(x -7)+8[/tex]

Rewrite as:

[tex]y = (x - 7)^2 + 6(x -7)+8[/tex]

Expand

[tex]y = x^2 - 14x + 49 + 6x -42+8[/tex]

Collect like terms

[tex]y = x^2 - 14x + 6x -42+8+ 49[/tex]

[tex]y = x^2 -8x +15[/tex]

To write in vertex form, we have

Subtract 15 from both sides

[tex]y -15= x^2 -8x[/tex]

Divide (-8) by 2; Add the square to both sides

[tex]y -15+ (-8/2)^2= x^2 -8x + (-8/2)^2[/tex]

[tex]y -15+ 16= x^2 -8x + 16[/tex]

[tex]y +1= x^2 -8x + 16[/tex]

Expand

[tex]y +1= x^2 -4x - 4x + 16[/tex]

Factorize

[tex]y +1= x(x -4) -4(x - 4)[/tex]

Factor out x - 4

[tex]y +1= (x -4)(x - 4)[/tex]

Rewrite as:

[tex]y +1= (x -4)^2[/tex]

Make y the subject

[tex]y= (x -4)^2 - 1[/tex]

The vertex is:

Cylinder X

O A. 45 cm
OB.
712 cm3
O C.
178 cm3

Answers

Answer:

Volume of Cylinder X = 712 cm³

Step-by-step explanation:

Given:

Volume of Cylinder Y = 89 cm³

Radius of cylinder Y = 2 cm

Radius of cylinder X = 4 cm

Find:

Volume of Cylinder X

Computation:

We know that, Cylinder X and Cylinder Y are similar

So,

Volume of Cylinder X / Volume of Cylinder Y = [Radius of cylinder X / Radius of cylinder Y]³

Volume of Cylinder X / 89 = [4/2]³

Volume of Cylinder X / 89 = [2]³

Volume of Cylinder X / 89 = 8

Volume of Cylinder X = 8 x 89

Volume of Cylinder X = 712 cm³
