Answer: Galaxy c is the farthest

Step-by-step explanation:

Given:

The figure of an equilateral triangle with side length 14 in.

To find:

The height x of the equilateral triangle.

Solution:

We know that the height of an equilateral triangle is:

[tex]h=\dfrac{\sqrt{3}}{2}a[/tex]

Where, a is the length of side of the equilateral triangle.

It is given that the height of the triangle is [tex]x[/tex].

Putting [tex]a=14,h=x[/tex] in the above formula, we get

[tex]x=\dfrac{\sqrt{3}}{2}(14)[/tex]

[tex]x=\sqrt{3}(7)[/tex]

[tex]x=7\sqrt{3}[/tex]

Therefore, the height of the triangle is [tex]x=7\sqrt{3}[/tex].

Answer:

The length of the missing side is 7x-5

Step-by-step explanation:

Here, we want to get the value of the missing length

Mathematically, the perimeter of a triangle can be obtained by adding the lengths of its sides

So by subtracting the sum of the lengths of the two given sides from that of the perimeter, we get the length of the third side of the triangle

mathematically, we have this as;

13x-7 -(4x + 2 + 2x-4)

13x-7 - (4x + 2x + 2-4)

= 13x-7 - (6x -2)

= 13x -7 -6x + 2

= 13x-6x -7 + 2

= 7x -5

Answer:

82 notes

Step-by-step explanation:

The computation is shown below:

Given that

£1= 18.53 rand

and since Linz has £850 so he would get the equivalent of

= $890 ×  18.53

= 16,491.7 rands

Now he wants the 200 rand notes so we considered it as the  highest note

So, the greatest no of 200 notes would be

= 16,491.7 ÷ 200

= 82.45

= 82 notes

Answer:

This is an Exponential Decay

Step-by-step explanation:

A = 1200(0.85)⁶

The above expression is an Exponential Decay because 0.85 is less than 1

The formula for Exponential Decay

= y = a (1 - r)^t

We equate both equation together

Where

a = 1200

1 - r = 0.85

t = 6

Solving for r

1 - r = 0.85

r = 1 - 0.85

r = 0.15

Converting to Percentage

r = 15% decay rate

Answer:

Total cost= $100

Step-by-step explanation:

Giving the following information:

Each box has 10 brooms. Each broom is sold for $ 15

The charity earns $ 50 profit for each box of brooms.

First, we need to calculate the total revenue per box:

Total revenue per box= 10*15= $150

Now, the total cost:

Total cost= total revenue - total income

Total cost= 150 - 50

Total cost= $100

Answer:

Slope= -5

Step-by-step explanation:

Use the formula, (y2-y1)/(x2-x2)

4-(-6)/1-3 = 10/-2

10/-2 = -5

Therefore -5 is the slope

Answer:

She can buy 3 bracelets.

Step-by-step explanation:

$50 (Total price) - $12 (Airpod case) = $38

$38 - $9.50 (Bracelets) = $28.5

$28.5 - $9.50 = $19

$19 - $9.50 = $9.5

Answer:

1/2

Step-by-step explanation:

If you do this:

20:2=10

14:2=7

12:2=6

You get dimensions of smaller triangle which is a half from bigger one.

Answer:

scale factor is 1/2

Step-by-step explanation:

notice that the sides of ΔABC are one-half of the length of the sides 0f ΔDEF

Answer: 9 inch

Step-by-step explanation:

Given

Distance between city A and city B is 540 miles

Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation

suppose the distance between city A and B on the map is x

[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]

Therefore, the distance between city A and B is 9 in.

Answer:

X=11

Step-by-step explanation:

4 x 2 - X + 3 = 0

multiply 4 x 2

=8

subtract the 3 and 8 to the other side which will made it

-X = -11

and this can be divided by a negative so the answer will be

X = 11

Answer:  C. 3w + 8 – w = 4w – 2(w – 4)

(3w - w) + 8 = 4w - 2w -2(-4)

2w + 8 = 2w + 8

Answer:

4 gallons of gasoline per 1 mile

Step-by-step explanation:

Answer:12 miles per gallon.

| c - 7 | 《 17

- 17 《 c - 7 《 17

add sides 7

- 17 + 7 《 c - 7 + 7《 17 + 7

simplification

- 10 《 c《 24

Answer:

c - 7 ≤ 17

c ≤ 24

Step-by-step explanation:

The difference of c and 7 can be written as c - 7 or 7 - c.

Now, since c - 7 is less than or equal to 17, you need to add ≤ to imply that it's less than or equal to 17.

As always, write the 17 on the other side. Now you have an inequality.

If you just need the equation, it's c - 7 ≤ 17.

But if you want to solve for c, it would be c ≤ 24.

(bring the like terms together and isolate c.)

Answer:

Your answer would be

X^2-7

Hope it helps .

Good luck .
